No drug


the production process failed drug generally rubber-degree shape the process of softening, while the plastic mold factory is or metals, petroleum products despite the smell, but sound

new tire plants in general do not have the old toxic cleaning: the

dry ice cleaning method effectively ensure the machine's materials and processing quality. Dry ice cleaning method has been rapid worldwide development. Wantong cleaning systems, through high-pressure air in the future of granular dry ice particles sprayed into the work surface need to be cleaned, using temperature difference reflects the physics of different substances at different speeds resulting from the contraction. -78 Degrees Celsius when the dry ice particles come into contact with the dirt surface, will produce an explosion phenomenon of embrittlement, so that contraction and loose dirt, followed dry ice particles would be an instant vaporization and expansion of 800 times, product divestiture of a powerful force, will be dirt fast, completely detached from the metal surface: Wantong use of food-grade recycled carbon dioxide is a reflection of the many chemical products, by-products, so that they use and did not increase the amount of carbon dioxide in the atmosphere. Deeper, the dry ice cleaning replaces the use of toxic chemicals, thereby reducing harm from the source and waste. Made by liquid carbon dioxide dry ice particles without any trace of the final evaporation into the atmosphere, so the dry ice cleaning has also been dubbed green cleaning. "
