Plastic bags with identification of toxic hazards?

October 7, 2008 on 6:19 pm | In Tech | No Comments

banque iena anglais Many farmers markets, supermarkets are in a plastic bag loaded with food, in fact, there are a lot of toxic plastic bags, especially the colorful plastic color, which is in itself contains a lot of toxins. Because the color of renewable plastic bags belonging to the use of coloring agents usually contain benzo topiramate, is a highly carcinogenic substance, and access to food, could be transferred to the food, people with chronic poisoning. In addition, the latest research shows that plastic products is also a plasticizer carcinogen, and the regeneration process as simple and plastics and other reasons, its plasticizer with food, especially oily food more easily contact effusion.

folies travel mouscron petite rue click “People used to use ‘drug bags’, is both a victim of a carcinogen, unwittingly acting as a disseminator of the carcinogen.” Tongji University School of Medicine professor of environmental medicine Shu-Guang Li cautioned that a number of shops as soon as possible with thin The thin, with a sharp smell of renewable plastic bags loaded food like deep-fried dough sticks, carcinogenic substances leaking faster and more dangerous.

centrale leroy merlin lezennes Color masterbatch with the requirements

http://keynew.space rosamund pike gone girl Masterbatch pigment used, it should be noted pigment and plastic raw materials, with the relationship between the agent, the main points of their choice, as described below.

retarder i betong (1) of the pigment and resin and can not react to a variety of additives, strong solvent, the migration of small, good heat tolerance and so on. In other words, the masterbatch can not participate in a variety of chemical reactions. Such as carbon black can be controlled by the curing reaction of polyester plastics, polyester so you can not add carbon black pigment.

treinen netwerk noorwegen there As the plastic forming a high temperature, the pigment forming in the heating temperature does not break down color. Inorganic pigments generally good heat resistance, organic pigments and dyes less heat resistance, which should be in the selection of varieties of pigment caused enough attention.

cool art snake (2) of the pigment dispersed, force should be good coloring. Uneven pigment dispersion, the products will affect the appearance of performance; coloring pigment force poor, would increase the amount of pigment, raising the cost of materials. At the same pigment dispersed in various resin and coloring power is not the same, so they should pay attention to the selection of pigment.

etterforskningen i politiet 2013 The pigment particle size and dispersion relations have, the smaller the particle size pigment, dispersion, the better, the coloring is also strong.

refaire terrasse extérieure (3) should be aware of the other properties of pigment, such as for use in food, children’s toys on the side of the plastic products, the requirements should be non-toxic pigment; for the electrical side of the plastic products, electrical insulation should choose a good color; Respect for outdoor plastic products, to choose an aging weather-resistant properties of pigment, and so good.

http://allthree.site/2018 fiets zonder zadel Masterbatch production process is very strict requirements, generally wet process. Masterbatch by the water with abrasive material, phase change, washing, drying, granulation formed, is the only way the quality of products can be guaranteed.

dessus mur en pierre (1) ink method: As the name suggests, is in the ink adoption of masterbatch production Colorants production methods, that is, through the three-roll grinding, in the paint coating on the surface layer of low-molecular-weight protective coating. After the fine grinding paste and another carrier resin mixture, then roll plastic Xiaolian II aircraft (also known as twin-roll machine open chain), plastics, the last single screw or twin-screw extruder for granulation.

Stir ingredients coarse paste three-roll grinding paste two small plastic roller chain out of grain
(2) Irrigation: paint, water and dispersant through sanding, so that the pigment particles of less than 1μm, and through the phase-transfer law, so that the pigments into the oil phase, and then drying system was masterbatch. When compared to the need to use organic solvents, as well as the appropriate solvent recovery unit. Its flow chart is as follows:

At the same time, the carrier will be oily paint coating on the surface, so that the pigment dispersion stability and cohesion to prevent the paint.

hundepensjonater i bergensområdet visit (4) metal soap method: After paint is the size after grinding to reach around 1μm, and to a certain temperature by adding liquid soap, paint particles on the surface of each layer evenly by the wetting liquid soap dispensers to form a layer of liquid saponification, After adding salt solution and in the paint layer on the surface of the saponification reaction and generate a layer of protective coating of metal soap (magnesium stearate), so that so that the ground after the pigment particles will not give rise to the phenomenon of flocculation, and a certain degree of protection Fineness.
