Q:Can I marinate salted eggs with a plastic bucket?
May notA plastic PVC is often used, it is made of PVC resin, plastic resin increasing agent and anti-aging agent, and non-toxic. But the addition of plasticizer, antioxidant and other accessories are toxic, daily in PVC plasticizer, mainly using terephthalic acid two butyl phthalate two formic acid two ester etc., these chemicals are toxic, lead salt antioxidant stearic acid polyvinyl chloride is toxic.
Q:What are the processing methods of black masterbatch and what is more prominent than other plastic raw materials?
In addition, carbon black has a special contribution to the strength of products and the enhancement of conductivity. There are three types of information plates available in the Fu plastics website: single screw, double screw, and dense. Single screw method, using mixing machine materials after mixing by single screw extruder brace granulation, the carbon concentration in the general 18-20%, production process backward, poor environmental conditions, is eliminated by process, do not rule out some fledgling small factories still use the method of processing.
Q:How do plastics weld?
Plastic welding is limited to thermoplastic welding because only thermoplastics can be melted or softened while they are heated, while thermosetting plastics cannot be softened and remelted while they are heated.Hot air welding oxyacetylene similar to metal, but the latter with the former fire hot air heating. Hot gas welding process, the welding torch from the hot gas stream (typically 200 to 300 degrees Celsius temperature, flow rate of 15 ~ 60L/min) and the filler rod and welding pieces of the heating surface, when the material softening reached sticky state, filling rod continuous pressure into the weld. The filling bar material is the same as that of the base metal, usually round (about 3mm in diameter), and is welded by multiple bead welding. One drawback of the round filling rod is that the hollow bubbles are easily entrapped in the weld during the multi pass process, resulting in lower strength. This problem can be solved by using a triangular section welded rod. Typical materials for hot air welding include polyvinyl chloride, polyethylene, polypropylene, plexiglass, polycarbonate, POM, polystyrene, nylon, ABS and so on. The main advantage of hot gas welding is adaptive (flexibility), portable equipment and processing of large, complex parts can be simple. Hot air welding is suitable for irregular structures, but it is slow and the quality of welding depends largely on the skill of the operator. Therefore, it is seldom used in mass production, but it is suitable for repair operation.
Q:Is ABS plastic poisonous?
Of course, due to the application of different plastics will add different additives, but the difference is very big. Different plastic plastic additives are generally inorganic filler, glass fiber, pigment, antioxidant, anti UV agent, plasticizer and inorganic filler and glass fiber. The body is stable and has no toxicity to the mineral glass. The human body. The antioxidant and anti UV agent general dosage is small, but 1-2% of the components, of course the nature itself is non-toxic or low toxic to the human body. The most likely risk of plastic is PVC, the plastic additive content could even reach 60-70%, it is difficult to ensure there is no harm to human body.
Q:What plastic sunscreen?
PVC also has titanium dioxide and UV absorbers
Q:What is plastic made of?
Plastic refers to the resin (or in the process of using monomer polymerization) as the main ingredient, such as plasticizers, fillers, lubricants, additives such as colorants as auxiliary components, can flow in the process of forming materials.
Q:The lid of the vacuum cup is plastic. Will drinking water affect it?
Prepared according to the above requirements, there is a plastic cup or can be used as PP (5), HDPE (2) and anti porcelain plastic, for PP that are very familiar with, this is the microwave special plastic, in the formal process, harmful substances are not excessive.
Q:What kind of plastic grade does polyether sulfone resin (PES) belong to?
[heat resistance]The heat variant temperature is 200~220 DEG C, the continuous use temperature is 180~200 DEG C, and the UL temperature index is 180 DEG C.[water resistance]Up to 150 to 160 DEG C hot water or steam erosion at high temperatures from acid and alkali.[modulus of temperature, consul sex]The base modulus is almost unchanged at -100 to 200 degrees, especially above 100 DEG C, which is better than any of the thermoplastic resins.
Q:Does high strength polyurethane belong to plastics?
But now there are some materials that are both plastic and rubber, and it's difficult to identify which category, such as TPO, TPV, elastomer nylon (material for car tires)
Q:Plastic products in the injection process should pay attention to what?
When the material is formed, the molten material contacts the cavity surface and the outer layer is cooled immediately to form a low density solid shell. Because of the poor thermal conductivity of plastic, the inner part of the plastic part is cooled slowly to form a large solid layer with high density. Therefore, the wall thickness, cooling slow, high-density layer thickness is large contraction. In addition, the layout and number of inserts have direct influence on the direction of material flow, the density distribution and the shrinkage resistance. Therefore, the characteristics of plastic parts have great influence on the shrinkage size and direction.
