Q:What is plastic film material?

Plastic film material is plastic micelle, which is made by petrochemical enterprises from petroleum refining.

Q:What is the plastic basin made of?

Machines generally use injection molding machines, raw materials using PP and PE, the raw material price of more than 10000 a meal, and some can be used to feed prices at around 5000. Equipment price depends on your size, small injection molding machine plus two or three sets of film, about one hundred thousand on it.

Q:Characteristics and uses of CA plastics

Commercially available products can be divided into general cellulose acetate (acetyl - 37% - 40%). Plasticizers are often added as injection molded parts, such as toothbrushes, brushes, etc.. Cellulose acetate with a high acetyl content (40% to 42% acetyl), white, granular, powdery or cotton solid. The light stability, not easy to burn, in dilute acid, gasoline, mineral oil and vegetable oil in stability, swelling in chloroform, insoluble in acetone, methyl acetate, can dilute alkali erosion, has advantages of toughness, transparency, good gloss, good melt fluidity, easy molding. Dichloromethane homogeneous method using refined cotton linter and acetic acid with acetyl sulfate as catalyst, esterification, hydrolysis in the presence of dichloromethane solvent, can be combined with cellulose acetate acetic acid content in 60% + 0.5% range. The traditional method is to use dry cotton, acetic acid in the presence of catalyst activation, sulfuric acid, acetic acid and acetic anhydride with mixture of acetylation, then adding dilute acetic acid hydrolysis to belong to the degree of substitution, and catalyst, precipitation, acid washing, rice drying. After partial hydrolysis, cellulose acetate is called two, and the degree of esterification is 220~270. Without hydrolysis, that is, the degree of esterification, the gamma value of 300, said three cellulose acetate. Two cellulose acetate plastic handle, can do all kinds of tools of computer and typewriter alphanumeric keys, phone chassis, car steering wheel, textile equipment parts, radio switch and insulation, pen, spectacle frame and lens, toys, daily necessities, but also do desalination membranes. Three cellulose acetate, high melting point, can only match into solution processing, used as a movie film, X film, light film, electromagnetic diaphragm insulating tape, transparent container, the silver zinc battery.

Q:What is the plastic bag made of?

Method for identification of toxic plastic bags. The water detection method: put a plastic bag into the water, non-toxic can be surfaced, and poisonous won't rise; hand touch detection method: white or colorless transparent is non-toxic, the hand has a sense of lubrication, the surface like wax; color detection method: toxic haze or color yellow, red, black, feel sticky; jitter method: take a plastic bag shaking, crisp sound non-toxic; sound stuffy astringent toxic.

Q:Dissolve in 0.3 of the LDPE plastic raw materials what?

Linear low density polyethylene (English: Linear Low Density Polyethylene, referred to as: LLDPE), linear low density polyethylene (LLDPE), is a senior of ethylene and alpha olefins (such as -1, -1, butylene hexene octenes methylpentene -1, four -1) in the presence of catalyst, a copolymer with high or low pressure polymerization of density is between 0.915 ~ 0.9 low density polyethylene using 40 g / cm3.

Q:How do plastic materials come from?

Plastic materials: is made of macromolecule resin (polymer) as the main ingredients penetrate various auxiliary materials or additives, in particular temperature, has the plasticity and fluidity under pressure, can be molded into shape and maintain the same shape of material under certain conditions.

Q:What are the criteria for the classification of plastic materials at injection molding and extrusion?

The new plastic materials, manufacturers have set by type of good applicability, according to the model can be used, but not to say that the plastic extrusion grade no injection molding, injection molding grade plastic extrusion processing can not, some engineers to use the material properties, will use the technological method for solving extrusion or injection molding grade between the influence.

Q:What are the main raw materials of plastic products?

ABS plastic (acrylonitrile butadiene styrene) English Name: AcrylonitrileButadiene StyreneSpecific gravity: 1.05 g / cubic centimeter molding shrinkage: 0.4-0.7% molding temperature: 200-240 DEG C, drying conditions: 80-90 hours, 2 hoursThe material performance is 1, the comprehensive performance is better, the impact strength is higher, the chemical stability and the electrical performance are good. It is suitable for making general mechanical parts, reducing wear and wear parts, transmission parts and telecommunications parts

Q:What is the raw material for producing corn starch plastic film?

According to the current technical level, the production of 1 tons of starch requires 1.5 tons of corn, power consumption of 200KWh, coal consumption of 0.3 tons. If the 1 tons of starch into biomass plastics, can be processed into 1.01.2 tons of products, instead of common plastics, saving petrochemical resources, the country. Because there is no effective stimulating mechanism in the downstream market, the application of corn starch is still limited to the research area of modified starch. The industrialization of biomass plastics with corn starch as the main raw material will effectively stimulate the cultivation of corn and the production of cornstarch. Biomass plastics are gradually evolved from the further research and development of biodegradable plastics. It is gradually recognized that only by fully utilizing the natural and recyclable plant resources to develop and develop biomass plastics is a reliable way to achieve sustainable economic development. In the past 30 years, and in half a century, all countries in the world pay attention to and invest a lot of manpower and material resources of biomass plastics, mainly starch and biodegradable plastics mixing, carbon dioxide copolymer, biosynthesis of biodegradable plastics, and then generate a biosynthetic precursor chemical polymerization of biodegradable plastics in 4 categories. The latter three prices are higher, but the cost is higher, mainly used in medical materials, biomedical engineering and tissue engineering and other high-value products.
