Small-Scale Chinese Coating / Paint Production: Workshop Formula, Ratios & Method
In short: Small-Scale Chinese Coating / Paint Production: Workshop Formula, Ratios & Method. This entry documents a formula & ratios taken from Chinese practical-technology literature, written for small-scale makers and home producers. The text below is the full English translation of the original Chinese workshop notes, covering materials and quantities, the step-by-step sequence, and the practical cautions recorded in the source. Roughly 2690 words of English technical text, translated and preserved without editing. It is intended for experimental and reference use, not for regulated or commercial certification.
Metal cans lined with new paintThe corrosion prevention of metal cans and other containers is a problem that people have long paid attention to. In particular, the leakage and corrosion prevention requirements for the joints, seams and inner surfaces of thin metal iron cans used to hold food are particularly strict. It is a deliberate goal of the canned food processing industry to maintain sufficient sealing, protect food from contamination, and ensure sterility and freshness. Tin plating and chrome plating of tanks are old methods that have been used in the past. Switching to the vinyl spraying method can be said to be a big improvement. However, due to the poor viscosity and spread of this coating, the coating thickness is increased, which increases the cost of coating processing: the coating often flows on the vertical coating surface; during heating and hardening treatment, the thick coating prolongs the processing time and increases energy consumption; moreover, it is often difficult to remove the solvent in the coating agent, causing the food in the can to be contaminated and have an unpleasant smell, which affects the eating quality. Therefore, people have been working hard to find new methods of leakage prevention, corrosion prevention and preservation.American Katniss Richard Lintmeister recently proposed a new lining application method, which has improved the situation in this regard. The specific method is also very simple. As long as a certain ratio of a thixotropy substance - a thixotropic agent is added to the organic coating, the stability and strainability of the organic coating can be enhanced, thereby greatly improving its performance. The thixotropic agent he used was Cabot Corporation's Cab-0-Si1 (trademark) silica preparation. This preparation was …
