Coating technology: application method of casting coating

Core tip: 100g coating powder + 100g neutral water glass + 300g water ratio, pour it into the soymilk machine for full mixing, then pour it into the spray gun to spray on the hot (200-300 ℃) metal mold surface, the thickness is 0.2mm, the local thin part can be sprayed 0.3-0.4mm thick according to the product requirements, drying is OK About 20-30 pairs of molds can be sprayed In case of any discrepancy, the manufacturer's requirements shall prevail! Casting mold coating Color: black, white, red, yellow, etc 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 Paint Home News: 100g paint powder + 100g neutral water glass + 300g water ratio, pour into the soymilk machine to mix fully, then pour into the spray gun to spray on the hot (200-300 ℃) metal mold surface, the thickness is 0.2mm, local thin parts can spray 0.3-0.4mm thick according to the product requirements, drying can be done About 20-30 pairs of molds can be sprayed In case of any discrepancy, the manufacturer's requirements shall prevail! [casting mold coating] Color: black, white, red, yellow and other [main raw materials] special diatomite, removing 5-8% of the binding water, organic matter and impurities in the diatomite; Al2O3, SiO2; casting coating suspension agent (lithium-based concave soil, organic soil, etc.) [scope of use] metal mold surface, iron mold / aluminum mold / copper mold; [function] 1 ZD coating is used for heat insulation, temperature equalization, avoiding the impact and corrosion of metal liquid, so as to protect the mold and extend the service life of the mold to more than 1 / 3; 2 Prevent the cracking and white iron formation of casting products caused by local cooling too fast; 3 The adsorption time is up to 7 days, and the permeability is good Each demoulding can be treated with acetylene fumigation instead of demoulding agent, and only one casting can be poured for fumigation; [advantages] 1 Compared with phosphate coating, its unique physical properties determine its advantages; 2 Good ventilation; 3 Obvious heat preservation and insulation effect, melting point above 1650 ℃; 4 After spraying, the adhesive force is strong and it is not suitable to peel off Generally, repair is needed one week later ZD coating does not need to be sprayed every time as other coatings do, saving the tedious work of disassembling and assembling the molds due to spraying and repairing coating every day 5 The price is relatively cheap, greatly reducing the expensive production and casting costs due to the use of alcohol based coating or imported coating 6 Greatly improving the production efficiency 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,
