HPMC. Hydroxypropyl methylcellulose, a high-purity environmentally friendly content, and refined cotton as uncooked substance. The white powEPTobtained by means of a series of chemical processes is usually utilised as an additive in a lot of EPT.
HPMC cellulose hydroxypropyl methyl ether is made of highly pure cotton cellulose as uncooked material, treated with lye at 35-40 ordmC for 50 % an hour, pressed, crushed the cellulose, and appropriately aged at 35 ordmC to make the attained The regular diploma of polymerization of the alkali fibers is within the preferred range.
Put the alkali fiber into the etherification kettle, and etherify at 50-80 ordmC for 5h, the maXiHu (West Lake) Dis.mum stress is about one.8MPa. Then clean the components in very hot water at 90 degC to boost the quantity, and then dewater them in a centrifuge, and ultimately wash them repeatedly to neutrality.

About Asphalt Adhesive:
Asphalt is divided into two groups: normal asphalt and petroleum asphalt, and petroleum asphalt is largely used as an adhesive.
There are a few types of adhesives formulated with asphalt: hot-melt kind, solvent type and emulsion sort.
Asphalt is inexpensive, has superb drinking water resistance and alkali resistance, and has very good toughness. It is broadly used in civil building, eEPTly in the construction of roadways, bridges and properties.
But the oil resistance and solvent kind are poor, and heating has the drawback of softening inclination.
