Product using

PVC is actually a polymerization substance of ethylenel group, and its material is a non -crystalline material. PVC materials often add stabilizers, lubricants, auxiliary processors, color materials, anti -impactants and other additives in actual use. It has not flammable, high -strength, immersive, and excellent geometric stability. PVC has strong resistance to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated sulfuric acid, concentrated nitric acid, and is not suitable for contact with aromatic hydrocarbons and chlorine chloride. In addition, the term Person VS Computer in the game, abbreviated as PVC, and PVC humanoids are often referred to as PVC, etc.

Polyvinyl chloride, referred to as PVC (Polyvinyl Chloride) in English, is a VINYL Chloride Monomer (VCM) caused by peroxides, nitride compounds, etc.; Polymerized polymer. The average polymer and polymer of the chlorine chlorine is collectively referred to as chlorolythery resin.

PVC is a white powder with a non -fixed structure. It has a small degree of support, a relative density of about 1.4, a glassized temperature of 77 ~ 90 ° C, and a decomposition of about 170 ° C. The stability of light and heat is poor. The sun exposure will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, cause discoloration, and the physical mechanical properties also decrease quickly. In practical applications, stabilizers must be added to improve the stability of heat and light.

The PVC molecular weight of the industrial production is generally within 50,000 to 110,000, and it has large and diversified properties. The molecular weight increases with the decrease in the aggregation temperature; no fixed melting point, 80 ~ 85 ° C began to soften, 130 ° C becomes a viscous elastic state , 160 ~ 180 ° C began to transform into adhesive; there is good mechanical performance, about 60MPa resistance, impact strength 5 ~ 10kJ/m2; excellent dielectric performance.

PVC used to be the largest universal plastic in the world, and its applications were very wide. Building materials, industrial products, daily necessities, floor leather, floor bricks, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fiber, etc. are widely used.

Color

Poetry of polyvinyl chloride and poor light resistance. At 150 ° C, the hydrogen chloride began to decompose, and the number of adverse reactions occurred with the amount of plasticizer content. In addition, the impact of pigments on PVC is reflected in whether the pigment is reacted with other components of PVC and other components that forms PVC products and the resistance and heat resistance of the pigment itself. Some ingredients in the color agent may promote the degradation of resin. For example, iron and zinc ions are catalysts for PVC resin degradation reactions. Therefore, the use of iron oxide (red, yellow, brown, and black) pigments or zinc oxide, zinc sulfide, and Lide powder white pigments will reduce the thermal stability of PVC resin. Some colorants may occur with the degradation products of PVC resin. For example, if the green pigment is poor, the acid is resistant to acid, so during the PVC color processing process, it will interact with the hydrogen chloride generated by the PVC to lose the due color. Therefore, as far as PVC is concerned, considering the characteristics of the resin and related additives used, the characteristics of the pigment are combined with pigment. Pay attention to the following issues when choosing a color.

1. Some metal ions in the pigment will promote the decomposition of polyvinyl chloride resin as shown in Figure 1.

The measurement method is the hue change when the pigment polyethylene is heated to 180 ° C. Because the pigment contains metal ions to accelerate the decomposition of PVC, hue changes are caused. At the same time, it should be noted that adding color croissance red can make the color difference between the PVC. If it contains calcium, the color difference is small; the color of the manganese contains a large difference, which is caused by metal such as manganese promoting PVC hydrogen chloride.

Sulfide color agents (such as cadmium red, yellow, etc.) are used for polyvinyl chloride coloring, and may be liberated by color sulfide. This type of coloring agent should not be mixed with lead stabilizers, so as not to generate black lead.

2. The effect of pigment on polyvinyl chloride electrical insulation

Like the cable material and polyethylene, the electrical properties after coloring should be considered. In particular, because polyvinyl chloride is more insulating than polyethylene, the impact of the pigment is greater. It shows that choosing inorganic pigments PVC is better for its electrical insulation (except for furnace black, sharp titanium titanium dioxide).

Migration

Migration only occurs in plastic increase PVC products, and when using dyes or organic pigments. The so -called migration is a soluble dye or organic pigment that exists in the surrounding solvents. Through the surface of PVC products through plasticizers, those dissolved dye (Yan) particles are also brought to the surface of the product. Slice, solvents, color seepage or frost.

Another problem is "scaling". During the coloring agent, when the coloring processing is machined, it is left out of the system because the color of the color is poor or incompatible at all. Essence

Tolerance

Refers to the ability to resist various climate. These include visible light and ultraviolet light, moisture, temperature, atmospheric chloride, and chemicals encountered during the use of product. The most important weather resistance includes the durability of non -fading, powder resistance and physical properties. The organic pigments are bad due to their different structures. In addition, in the formula containing white pigments, the weather resistance of pigments will be seriously affected.

The fading, darkening or color change of the pigment is generally caused by the reaction gene of the pigment. These reactive genes can occur with water or chemicals in the atmosphere -acid and alkali. For example, cadmium yellow will fade under the action of moisture and sunlight. Losalhong has a good optical resistance, suitable for most household applications, and severely fades in outdoor use of acid and alkali ingredients.

The measurement method of dehydrogen chloride is based on JIS-K-6723, and the determination temperature is 180 ° C. Based on the time of non -coloring polyvinyl chloride complex, the extension or retracting time is divided by 5%and 10%, and negative values indicate accelerated decomposition.

stability

The softening point of polyvinyl chloride resin is low, about 75-80 ° C, and the crisp temperature is lower than -50 ~ -60 ° C. Most products should not exceed 55 ° C for a long time, and the special formula can reach 90 ° C. If the polyvinyl chloride resin is pure head-sexual phase connection is afraid of the line structure, there is no branches and unsaturated keys inside, although the C-CL key can be relatively small, the stability of polyvinyl chloride resin should be relatively high. Essence However, even with high purity polyvinyl chloride resin, it starts to renew with hydrogen chloride gas above 100 ° C or by ultraviolet radiation. Explain that there are pointed groups or unstable structures in their molecular structure. The longer the time, the more degradation, the higher the temperature, the faster the degradation speed, and faster the decrease in oxygen or air.

Electrical performance

Polyethylene is a polar high polymer. It has a greater affinity for conductive substances such as water. Therefore, the resistance is smaller than the non -polyetry of polyolefins, but there is still a high volume yin and breakdown voltage. The polar group of polyvinyl chloride is directly attached to the main chain. Below the glass -based temperature, the occasional chain segment is limited by the main chain atom of the frozen structure. High -frequency insulation material. When the electrical wire insulation is used, the electrical insulation of the suspended resin is 10-100 times higher than the floating resin. The presence of degradable chloride ions will reduce the insulation.
