What should I do if a PC product cracks appear after being sprayed?

1. This crack is mainly due to the fact that the material PC did not completely release the internal stress at the buckle position, which led to cracking of the spray during the curing and heating process. Solution: Before spraying the material PC, put it into a baking oven and bake it at 80 degrees for 30-120 minutes--you need to try it yourself for the specific time.

2. Reason: The internal force in the product has not been eliminated. There is a problem with the diluent used for injection. The processing temperature is too high and the cheap PC material is carbonized. Treatment method: During the injection molding process, the pressure should be appropriate, especially the back pressure should not be too large, which may easily cause excessive internal stress in the product, deformation and cracking. The adjustable range of injection molding is relatively small, and the stress in the product can also be relieved through post-treatment.

3. Causes the product to crack after oil injection. This is because alcohol may chemically or physically react with PMMA materials, destroying its original stability and integrity. To avoid this situation, it is recommended to avoid using alcohol-containing solvents or additives during injection. At the same time, it is also possible to consider pre-treating PMMA products, such as improving their surface hardness or increasing their cracking resistance, to enhance their adaptability to the oil injection process.

4. Will it be brittle without oil spray? Due to the differences in heat resistance and physical characteristics of various brands of PC materials, the melt glue temperature, even the baking temperature and baking time, will have a significant impact on the impact resistance of injection molded parts. As long as the fluidity of the melt glue is sufficient to fill the mold, it is best to use a lower temperature to produce it to prevent the injection molded parts from becoming brittle and causing unstable strength.

Will PC material become brittle when encountering gasoline?

1. No;PC is the abbreviation of polycarbonate resin; this type of resin has solvent resistance. Besides, gasoline is a non-polar solvent, an alkane.

2. PC will not interact with general lubricating greases, oils and acids, and PC is also stable in pure gasoline. It cracks in carbon tetrachloride and dissolves in solvents such as trichloromethane, dichloroethane, and cresol.

3. If you say this, under normal circumstances, he will become brittle after encountering oil, so you must pay attention and try to stay as far away from the oil as possible.

4. Why does PC add color masterbatch crack when touching gasoline? On the one hand, anonymous users may have poor strength and toughness, rice, electricity, rice, rice, and how much less a meter, rice, and how much less a meter, rice, and rice, a small amount, rice, and a small amount, e, and a small amount, they may be because the stress has not been completely released. Annealing treatment of plastic products refers to the existence of internal stress in the product product due to uneven plasticization of the plastic in the barrel or uneven cooling rate of the product product in the mold cavity, which leads to subsequent deformation of the product product. Cracking. Aging and other reasons.

5. Gasoline properties: Gasoline is a non-polar solvent, mainly composed of alkanes. This chemical property may not be fully compatible with the material of the PC bottle, and long-term contact may cause the material to age, deform or crack. Safety risks: Due to the volatility and flammability of gasoline, storing gasoline in inappropriate containers increases the risk of fire and explosion. PC bottles may not effectively prevent the evaporation and leakage of gasoline, causing safety hazards.

Why does PC polycarbonate pipe crack when encountering engine oil?

1. The main performance defects of PC are that its hydrolysis resistance is not high enough, it is sensitive to notches, it is resistant to organic chemicals, and it has poor scratch resistance. It will turn yellow after long-term exposure to ultraviolet light. Like other resins, PC is susceptible to impregnation with certain organic solvents.

2. Polycarbonate performs well in chemical corrosion resistance, especially in oil resistance. However, due to its amorphous nature, the packing between molecules is not very dense, which makes it susceptible to the influence of certain organic solvents. For example, aromatic hydrocarbons and chlorinated hydrocarbon solvents can cause it to swell or dissolve, which may cause solvent cracking. In addition, polycarbonate is also slightly deficient in alkali resistance.

3. Polycarbonate has excellent oil resistance. After being soaked in natural gasoline and lubricating oil, the size and quality of the product remain basically unchanged. Aromatic hydrocarbons and chlorinated hydrocarbons can cause them to swell or dissolve, causing solvent cracking. Polycarbonate has low water absorption, but it will cause hydrolysis and molecular chain breakage when exposed to high temperature and high humidity for a long time, leading to cracking of the product.

4. The influence of sulfur-containing elements in lubricating grease on polycarbonate (PC) materials is mainly manifested in chemical erosion leading to molecular chain breakage, synergistic effect of internal stress accelerating crack propagation, and oxidative degradation caused by high temperature decomposition products, which ultimately leads to embrittlement and cracking of the material.

This is the end of the introduction of whether PC materials will crack when exposed to oil and how to solve the problem. slot machine ph casino,slot ph casino,slot machine casino,slot casino,slot ph,BAY888.com The world's leading slot game platform, providing exciting gaming experience and generic rewards.
