Deliver, Shipping And Serving

Before the sale, we confirm the demand for the product with the customer, and quote the customer according to the product drawings or product samples provided by the customer. After waiting for the customer to confirm the quotation, the company will open the mold order through the customer.The production of the test mode will be carried out, and the test mode can be completed in 20-30 days from the receipt of the order. After the customer confirms that the sample is OK, we will carry out mass production according to the order quantity, and the general delivery time is 3-7 days. After the sale, we will deal with the products with abnormal quality. If the products produced have quality problems, we will reply to the improvement report if the customer complains. If the products cannot be used, our company will arrange replenishment and finally meet the requirements of the customers.

Factors that are more easily affected in the production of plastics

Fillers, also known as fillers, fillers, is to reduce the cost and/or improve some properties of products and added to the polymer material matrix of solid substances, the choice of fillers to consider the main factors:

1. Low price

The price of filler has a great influence on the cost of plastics. The specific gravity of polyvinyl chloride plastic that adds filler is 2~3 times of that that does not add filler, accordingly the specific gravity of polyvinyl chloride plastic that adds filler increases rapidly with the increase that adds amount, so calculate cost according to weight to compare according to volume to calculate cost accurate, it is necessary to consider volume cost in application respect. The small proportion of filler is beneficial to the volume cost.

2. Oil absorption

That is, the ability of filler to absorb plasticizer. It depends on the fineness of filler and the variety of filler and plasticizer, the cost of plastic increases as oil absorption increases.

3. Electrical properties

Adding calcined clay can improve the electrical insulation of plastics. Calcined clay is to remove crystal water and other impurities in the calcination process of kaolin. The forging temperature affects the electrical insulation of plastics, usually 600~700°C. Filler can also improve the thermal deformation of cable material, adding a small amount of carbon black, can improve the weather resistance of plastics. A large amount of carbon black can reduce the electrical insulation, and can prepare semiconductor polyvinyl chloride plastics. Small water absorption filler is beneficial to electrical insulation.

4. Influence on physical properties

In soft polyvinyl chloride plastics, tensile strength, tear strength and elongation are decreased and hardness is increased when the amount of filler is increased. When larger particles are used, the loss of tensile strength and tear strength is greater, while when smaller particles are used, the elongation decreases greatly.

Clay makes polyvinyl chloride plastic harden action is bigger than calcium carbonate, namely hardness increases bigger, elongation decreases bigger. Due to the difference of the absorption, specific gravity, hardness, dispersion, particle size and particle size distribution of the plasticizer, the influence of various fillers on the physical properties of plastics is also different.

5. And purity

Because the plastics may react with the impurities in the filler, the purity of the filler is required. Metal impurities have been shown to react to barium/cadmium-type stabilizers, and trace amounts of iron, manganese, copper, and a smaller amount of aluminum have a greater effect on the efficiency of the plasticizer. The existence of sulfur due to vulcanization produced sulfide, lead stabilizer pollution. When calcium carbonate is used in white or other easily infected light-colored PVC products, the content of trace elements is recommended to be limited to the following:

A large number of fillers used in PVC processing are calcium carbonate, clay, barium sulfate, titanium dioxide and so on. Barium sulfate, titanium dioxide and calcium carbonate are mainly used in rigid plastics. Calcium carbonate clay is mainly used in soft plastics. It is advantageous to add calcined clay in the insulated cable section. Calcium carbonate is mainly added in the cable material of the protective layer, and aluminum hydroxide, calcium carbonate and talcum powder are also added in the film to reduce the cost.

The development direction of fillers is to coat the surface of fillers by various methods in the preparation process. The main benefits of surface treatment of calcium carbonate are: reduce the tendency of calcium carbonate agglomeration, improve the processing performance, which is beneficial to the development of continuous high-speed extrusion process for plastic processing. With stearate surface coating treatment of calcium carbonate other benefits are: oil absorption is small, can reduce the amount of plasticizer; Perfect and effective hydrophobicity and appropriate low plasticizer content, thus improving the electrical properties; The thermal stability is improved by the addition of calcium stearate in the coating layer. It is not necessary to add lubricant in plastic processing, which can simplify the batching process.
