    Core tip: in recent years, the price of PVC raw materials in China has increased substantially, which has led to the price increase of some building materials However, due to the oversupply of plastic doors and windows in the market, the price of plastic profiles and doors and windows has declined all the way, and some production enterprises are in a state of loss The only effective way for the plastic door and window enterprises is to replace the original inefficient and toxic formula additives by the development and application of new efficient, low lead, non-toxic and anti bacteria formula additives, improve the product performance and document times, and form different characteristic products, so as to widen the distance in price and meet the needs of different climate fields, different grades of buildings and consumer groups Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings news: in recent years, the price of PVC raw materials in China has increased substantially, which has led to the price increase of some building materials However, due to the oversupply of plastic doors and windows in the market, the price of plastic profiles and doors and windows has declined all the way, and some production enterprises are in a state of loss The only effective way for the plastic door and window enterprises is to replace the original inefficient and toxic formula additives by the development and application of new efficient, low lead, non-toxic and anti bacteria formula additives, improve the product performance and document times, and form different characteristic products, so as to widen the distance in price and meet the needs of different climate fields, different grades of buildings and consumer groups In order to improve the impact resistance of plastic profile, the impact modifier should be added or the new impact modifier ACR should be used instead of CPE In areas with high heat and ultraviolet radiation, appropriate dosage of titanium dioxide and UV absorber should be added to improve the anti-aging properties of plastic profiles In high-rise buildings in coastal areas, special-shaped materials with a and B wall thickness (2.8mm or 2.5mm) and large cavity shall be used to improve the wind pressure resistance of plastic doors and windows The lead-free or low lead formula such as calcium zinc rare earth or organotin stabilizer is used to replace the lead salt formula, so as to meet and enhance the environmental protection awareness of some consumers At present, it has become a basic national policy of many developed countries to strictly limit the lead content in products China still has a considerable gap in this regard, and efforts should be made to improve it The development and production of activated micro light calcium carbonate and nano calcium carbonate provide a certain space for reducing the cost of raw materials on the premise of ensuring the physical and chemical properties of plastic profile In recent years, two breakthroughs have been made in the application of calcium carbonate: one is to use fatty acids and various coupling agents to treat the surface of calcium carbonate to improve its surface activity and affinity with PVC molecules; the other is to refine the calcium carbonate particles to increase its compatibility and dispersion with PVC molecules Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
