General abroad do print is used as the PANTONE color standard, thus ensuring the print colour of identity. In China are also increasingly popular and use.

On Several key issues Black Masterbatches

September 23, 2009 on 9:55 am | In Tech | No Comments

Black masterbatch quality of the decision on the following factors: the dispersion degree, covering power, rheology, compatibility, stability, color intensity.

A higher degree of dispersion

Black Masterbatch for the use of carbon black production. Health and carbon black is a very tricky and dirty mixture, which is filled with dust, light weight, was fluffy-like. Unless the use of large-scale treatment measures, otherwise it will smear machines and workers, so that the working environment has become dirty. Because of this, casting resin, generally choose a carrier, which is a black masterbatch to complete the pre-dispersion of carbon black. The resin carrier is clean, free-flowing and easy to use. In addition, the carbon black apart from the dirty, there is a feature that is difficult to dispersion. If the injection molding directly to the health of carbon black, when melted, rendering the outcome will be very poor. There is no dispersion of carbon black stripes and spots, if leaning against the colored regions where less will be marked next to appear. The standard injection molding machine is not an effective carbon black dispersion of Health.

Carbon black dispersion of the performance of this difficult plagued masterbatch manufacturer. Use single or double screw extruder production of high-load black masterbatch dispersion of very poor. When the end-users of these black master batch mixing or die casting, its performance is only marginally better than the carbon black, but the effect was equally unsatisfactory. In order to achieve a stable and high dispersion, it is essential to use a high level of shear Ta River sealing machine to mixed carbon black, such as the FCM or BANBURY mixture. With sufficient strength, these mixers can make carbon black and basic resin completely mixed together. The use of carbon black type also affects the dispersion of. The smaller the particles of carbon black dispersion on the more difficult.

The application of a thin wax is the most emphasis on dispersion of requirements. Poor masterbatch dispersion from the corner of the end product can be easily seen by the naked eye. In addition to the lack of beauty, the film where the poor dispersion of carbon black significantly reduces the wind of the performance of black films. A good dispersion of small particles are the main features of industrial fibers, these fibers used for rope, yarn, carpets, and other industries. Large machines with more than 5,000 meters per minute rate of 30,000 shares at the same time to produce fine fibers. If the masterbatch dispersion bad, we would be cutting the fiber, resulting in production downtime.

Covering force stronger

Decide the quality of black masterbatch The second factor is the covering force, for the use of waste or recycled polymer masterbatch, this factor is particularly important, in these circumstances, the black, is meant to cover the waste in the other color. The shading power of large particle carbon black poor and difficult to cover all the other colors in the lower result, received only a departure from the final product color. In the melting process, the correct first choice with high shading ability of carbon black to cover the capacity of the existing color coverage of the so-called power.

Better mobility

Decide the quality of black masterbatch A third factor is the rheology and mobility. If a masterbatch itself has a good dispersion, but it will not flow into the material to be molded, it is not produced satisfactory results. In general, the grounding for the production of masterbatch resin has a high flow variability. In order to save costs, a number of masterbatch production of commercial re-use of materials, waste or recycled materials as the resin carrier. The flow of such a masterbatch production of the performance will be significantly reduced, if the rheology is not good, mold cycle time and the appearance of trade unions in handling trouble. It is noteworthy that, if the dispersion and rheological behavior is not high, and some end-users will be by increasing the dilution ratio to compensate, but this will only increase the cost of the use of masterbatch. With minimum dilution ratio of the masterbatch can be produced uniform, a good black dispersion.

Compatibility bigger

Compatibility black masterbatch quality of the decision of the fourth factor. If the masterbatch is to use the chips or recycled materials produced, then it may contain contaminants or other non-melting polymer. This will cause some unpredictable and difficult to bound the trouble of wasting time to the final consumer and raw materials. At this time, you can use to produce high-quality rendering resin masterbatch, masterbatch in the melting process have good compatibility. High-quality masterbatch can be used LLDPE, LDPE, HDPE, PP, PS, SAN, PA, and other materials to produce. If you have indicated engineering-level and rigorous physical properties, then a special polymer masterbatch could be obtained. Several large international masterbatch producers, are conducting research in an attempt to produce a so-called “global access” masterbatch. The masterbatch can be broad-based and other raw materials capacity, good rheology, can be applied flexibly.

Stability to be consistent with

In today’s globalized economy, international customers of the masterbatch quality, raw materials that require high performance and stability is absolutely necessary, and this is also the decision of the quality of black master batch fifth factor. The stability of a major manifestation is the proportion of stable carbon black. If the percentage of carbon black fluctuations, then the required amount of molten masterbatch is not the same, to produce products that can not be the same color. Ultimately reflected in a number of producers: the dilution of their requirements are usually more than 5-8% difference, depending on the time of manufacture masterbatch manufacturers put the amount of material. Clearly this is unacceptable. Of course, other factors such as liquidity into the melt and the dispersion of the investment should Charging Capacity of each batch is consistent.

Intensity should be clear

Decide the quality of black master batch A final factor is the color intensity. Market, there are various types of carbon black masterbatch can be used for coloring, but the various types of colors and prices are also very different. Large particles than small particles of carbon black carbon black has a lower degree and a different background color. Large granular masterbatch for film production, such as garbage bags, but not for the production of those who pay attention to aesthetic products, such as TV signboards or in need of anti-ultraviolet film or topical areas such as agricultural pipe. For these products, only the use of higher-priced small particles of carbon black. In addition, the low transparency is also a characteristic of small particles of carbon black.

General Classification and application of carbon black

SRF carbon black is generally used that do not require strong coloring power, high coverage or to UV protection, garbage bags production. Colors tend to gray blue, cheap and relatively easy to dispersion, so those who had only equipped with single or double screw extruder of the masterbatch small firms would choose such a carbon black. HAF carbon black particles in the size of half of SRF carbon black particles, but the coloring strength is its two-fold. Brownish-red, its UV protection was stronger than carbon black SRF, and cost less than the P carbon black. It has good coverage ability, can be applied in many ways. P carbon black for UV applications as well as the food industry, was red and blue. JET carbon black has the most satisfactory color shadows, dark, and shiny black. It is the smallest particles, but it is not easy in the dispersion. Only those with a high shear mixer using the JET carbon black manufacturers to obtain the same degree of dispersion. It is also the most expensive ordinary carbon black. Cost comparison shows that more expensive than the cheapest masterbatch masterbatch can be produced economically get better results.

What is the Color Masterbatches?

August 21, 2009 on 4:52 pm | In Tech | 2 Comments

Color Masterbatches (Color Master Batch) is a new type of polymer materials dedicated colorants, pigments, also known as preparation of materials (Pigment Preparation).

It consists of pigments or dyes, and additives vector composed of three basic elements, is the extraordinary amount of pigment or dye evenly attached to the resin contained in the aggregate have been, can be said to concentrate pigment (Pigment Concentration), so shading power than his own pigments.

Color Masterbatches is a kind of simple, said the extraordinary amount of pigment or dye evenly attached to the resin contained in the aggregates obtained.

Second, the masterbatches What are the basic ingredients?

Color Masterbatches for the basic ingredients:

1. Pigment or dye

Pigments are divided into organic pigments and inorganic pigments.

Commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, light red, red macromolecules, macromolecular yellow, yellow Everlasting, Everlasting, purple, red and other azo.

Inorganic pigments commonly used are: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc.

2. Vector

Is the matrix of the Masterbatches. Color Masterbatches with exclusive products generally the same resin as a carrier resin, the compatibility of the two best, but we must consider the mobility of carriers.

3. Dispersant

To paint and are no longer distributed evenly cohesion, the melting point of dispersing agent should be lower than the resin, and resin has good compatibility, and paint a better affinity. The most commonly used dispersing agent as follows: low-molecular-weight polyethylene wax, stearic acid salt.

4. Additives

Such as flame-retardant, Zengliang, antibacterial, anti-static, anti-oxidation, such as species, unless the customer requests, generally do not contain the above-mentioned masterbatches additives.

Third, Color Masterbatches what species and grade points?

Color Masterbatches commonly used classifications are as follows:

Classification by Vector: If PE Masterbatches, PP Color Masterbatches, ABS Color Masterbatches, PVC Color Masterbatches, EVA Masterbatches, etc.

By end-use categories: Color Masterbatches, such as injection, blow molding Color Masterbatches, Color Masterbatches, such as spinning

All varieties can be divided into different grades, such as:

1. High injection Color Masterbatches:

Packaging for cosmetics, toys, electrical appliances and other senior products shell.

2. Ordinary injection Color Masterbatches:

For general daily use plastic products, such as industrial containers.

3. High Blown Color Masterbatches:

Blow for the ultra-thin coloring products.

4. General Film Color Masterbatches:

For general packaging bags, woven bags of blow molding coloring.

5. Spinning Color Masterbatches:

Coloring fiber for the textile spinning, Color Masterbatches fine pigment particles, at high concentrations, coloring power, heat, good light-fastness.

6. Low-level Color Masterbatches:

Used in the manufacture of color do not ask for much of the lower quality products, such as trash, such as low-grade container.

7. a dedicated Color Masterbatches:

Is based on user-specified products for the plastic variety, choose the same plastic as the carrier of the masterbatch produced. Such as PP Color Masterbatches, ABS, respectively, choose Color Masterbatch PP, ABS as a carrier.

Universal Masterbatches: also used some kind of resin (often low-melting-point of the PE) as a vector, but it can be used in addition to its carrier resin other than the coloring resin.

8. Universal masterbatch

Universal masterbatch is relatively simple and convenient, but many shortcomings, the proposed user selection of exclusive Color Masterbatches.

Color Masterbatches special heat-resistant grades are generally used for products suited to the plastic, under normal temperature, can be assured that use. Only in the following circumstances will cause varying degrees of change, first, the temperature exceeded the normal range, one stands too long.

9. Color Masterbatches coloring coloring compared with the granulation has the following advantages:

1). Coloring and a completed product to avoid the coloring of plastics granulation heating process, the protection of good quality plastic products.

2). To make plastic products to simplify the production process the most.

3). Can save a lot of power

PVC heat stabilizers mechanism

October 30, 2008 on 7:08 pm | In Tech | No Comments

Where the polymer to improve the heat stability for the purpose of adding additives can be referred to as heat stabilizers. In addition to the small amount of heat stabilizer used in rubber processing and other resin, mainly used for thermal stability of a very prominent problem of PVC processing. As a result, often has said the heat stabilizer refers specifically to the use of PVC and PVC copolymer of heat stabilizers.

The thermal degradation of PVC in the process, almost no single, but generated a lot of HCl. PVC thermal degradation mechanism is very complicated, and similarly, heat stabilizer mechanism is very complex. At present, comprehensive research, the role of heat stabilizer can be summarized in the prevention of type (and HCl, to replace the instability of the Cl atom and the prevention of auto-oxidation) and type remedies (PVC and non-saturated parts of the response, the destruction of carbon ions are) two Species.

As follows:

1. Absorption and HCl, inhibiting its catalytic effect automatically. Stabilizer, including such categories lead salt, soap-type metal organic acids, organic compounds, epoxy compounds, amines, alcohols metal salt and salt-and metal salts, such as mercaptan. They can react with HCl, the suppression of HCl from PVC response.

2. PVC replacement elements of instability in the allyl chloride or t-carbon atom of chlorine atoms, the suppression from PVC. Organotin stabilizers such as PVC and chlorine elements of instability occurred in the original coordination, in the ligand, organic tin and instability in the replacement of chlorine atoms.

3. Polyene structure and the addition reaction, the destruction of large conjugate system formation, to reduce the shading. Unsaturated fatty acid contains a double bond salt or ester, with the PVC molecules conjugated diene double bond addition reaction took place in order to break the yoke of its structure, color suppression.

4. Capturing free radicals to prevent oxidation. If the accession to the phenolic heat stabilizers to block off HCl, is due to give the H-atom to free radicals and free radical molecules degradation of the PVC coupling, can not be formed with the O2 respond to the material, and has a stabilizing effect on the heat. This heat stabilizer may have one or both of several roles.

The ideal of PVC heat stabilizers should be a multi-function material, or some mixture of materials, they can achieve the following:

1. Lively exchange, the instability of the substituents, such as t-Cl connected to the Cl atom or allyl chloride, to form a stable structure;

2. Absorption and processing of PVC and in the process of release of HCl, the elimination of HCl automatic catalytic degradation;

3. Or passive and act as a catalyst for the degradation of the metal ions and other harmful impurities;

4. Through various forms of the chemical reaction can be blocked unsaturated key to the growth inhibiting degradation of coloring;

5. There is the best protection against ultraviolet shielding effects.

Fault injection molding machine classification

October 22, 2008 on 9:04 pm | In Tech | 1 Comment

Injection molding machine is a wide range of fault could be from a different point of view of its classification.

1. Fault by the occurrence, can be divided into:

(1) gradual onset fault. As a result of the initial injection molding machine performance arising from the gradual deterioration, most of the injection molding machine’s fault belongs to this failure. And the failure of such electronic control, hydraulic machinery parts of the yuan wear, corrosion, fatigue and creep, and so the process is closely related.

(2) sudden failure. Is a variety of factors, as well as the occasional outside influence and the role of co-produced, which went beyond the role of the injection molding machine can bear limit. For example: as a result of entering the bowl-iron overload occur and cause a broken screw; as a result of the breakdown and into the string of high-pressure injection molding machine electronic board. Such failures often occur suddenly, without any prior symptoms.

Unexpected failures occur in the injection molding machine using the stage, often due to the design, manufacture, assembly, as well as material defects, and so on, or operation errors, and regulations.

2. Demarcation according to the nature of the fault can be divided into:

(1) intermittent fault. Injection molding machine in the short term loss of some of its features, debugging will be able to resume a little repair, replacement parts and components do not need to.

(2) permanent failure. Injection molding machine has been damaged in some parts needed to replace or repair can be re-used.

3. Attainment affected by the fault can be divided into:

(1) complete failure. Injection molding machine led to the complete loss of function.

(2) partial failure. Lead to the loss of some of the features of injection molding machine.

4. Fault cause division, can be divided into:

(1) failure of wear and tear. As the injection molding machine failures caused by normal wear and tear.

(2) the wrong use of fault. Because of errors, failures caused by improper maintenance.

(3) the inherent weakness of failure. As the design, injection molding machine so that the emergence of weak links in the use of normal when the Trouble.

5. Failure by the danger of division, can be divided into:

(1) the risk of failure. For example, security systems need to move in failure due to the loss of the protective effect, resulting in personal injury and injection molding machine breakdown; electronically controlled hydraulic system failure caused by the fault, and so on.

(2) of the security failure. For example, security systems without the need for action when action; injection molding machine could not be activated when the start of the fault.

6. Injection molding machine fault by the occurrence and development of the law of division, can be divided into;

(1) random failures. Failure occurred at a time is random.

(2) there are rules of fault. The fault occurred in a certain regularity.

Each has its own failure of the main features of the so-called failure mode, or state failure. A variety of injection molding machine’s fault, it is quite complicated, but we can narrow it down several of the following: abnormal vibration, mechanical wear, the input signal so that computers can not be accepted, no output signal solenoid valve, hydraulic mechanical components break down, the ratio of linear disorders , The hydraulic pressure drop, leakage of hydraulic pump failure, hydraulic noise, circuit aging, abnormal sound, oil degradation, power supply Drop, enlarged board of exporting no SARS, temperature and other out of control. Different types of injection molding machine failure mode of a variety of different proportion.
