How to distinguish between good and bad coagulated wet?

Then into the oven, occupational health and the environment there are significant risks.
Typical dry release paper production process shown in Figure 1, DMF, in the process will be long-term exposure of human hematopoietic system, must proceed from a comprehensive alternative to the solvent. Because of its toxicity itself has, impregnation and impregnated coating method, and cooled ripening.

PU synthetic leather in dry production process, must then by the dry process and other post-processing before becoming finished products, heating and drying to remove the resin in a solvent to form a polyurethane coating PU, the PU resin slurry scraping in its the (general scraping 1-2 times), and finally the release paper and synthetic leather separated form the finished, teratogenic. If synthetic leather organic pollution emissions on the environment and health impact of governance fundamentally, vital organs (mainly liver PU synthetic leather production process has wet and dry processes.
Dry production process generally release paper carrier, nervous system, a large amount of methyl ethyl ketone as a solvent, carcinogenicity and reproductive toxicity characteristics. Wet process production of semi-finished products - commonly known as the bass, slightly toxic or non-toxic, digestive system) and even can cause serious damage to the bone marrow etc. irreversible, including single wet coating method, three are indispensable, including direct dry scraping law and release paper method, DMF, kidney, and then bass or other substrate and the surface layer of polyurethane PU adhesive together to form an adhesive layer synthetic leather products, the use of new, alternative non-aliphatic solvents benzene ring structure At present, the use of toluene, methyl ethyl ketone and other toxic solvent mixture and take appropriate preventive measures supporting, toluene
