Henan cellulose ether hydroxyethyl methyl cellulose, hydroxypropyl methyl cellulose Which is good price

Resin powder, he studied in depth screening of various solvents, adsorption powder screening, resin powder of the storage period, the production of mortar resin powder storage period, and supporting test other boards. Hazard A: Odor larger production, construction workers more harmful; hazards II: resin powder shorter shelf life, usually valid up to four months (or choose slower volatile solvents), this is the experiment chamber storage conditions. So zoom to individual small factories, management is poor, it is difficult according to the requirements of the storage period when you are finished using the batch, resulting in great risk. Hazard three: the production of mortar resin powder storage period is shorter, usually valid up to four months (or choose slower volatile solvents), this is laboratory storage conditions. So how to ensure the site's product shelf life is very important, and this failure is very dangerous, and mortar adhesion becomes poor, and polystyrene board not binding and can not be broken boards. Hazard Four: This resin powder produced mortar, if the quality control is good, within the warranty period, sticky EPS board tentatively also will; but many people regard him as a lower cost of a magic wand, stick extruded sheet , polyurethane panels, rock wool, ceramic tile, and even in the surface mortar, that harm is even greater! !
