Introduction to Hydroxypropyl Methyl Cellulose HPMC Hydroxy Propyl Methyl Cellulose Ether WH200

Hydroxypropylmethylcellulose (HPMC), hvis kinesiske navn er hydroxypropylmethylcellulose, er en semisyntetisk, ikke-ionisk celluloseether opnået ved kemisk modificering af naturlig cellulose. Dette hvide pulver kan danne en gennemsigtig viskøs opløsning efter opløsning i vand. Den har fremragende fortykkelse, vandophobning, stabilitet og filmdannende egenskaber. Det er et uundværligt multifunktionelt additiv inden for mange områder, såsom byggeri.

Characteristics and advantages of Hydroxypropyl Methyl Cellulose HPMC Hydroxy Propyl Methyl Cellulose Ether WH200

Fremragende vandopløselighed: Det kan hurtigt opløses i koldt vand for at danne en klar og stabil opløsning.

Effektiv fortykkelse og vandretentionsevne: Forøg materialets viskositet, reducerer effektivt vandfordampningen, og forbedre arbejdseffektiviteten.

God stabilitet: Det har god stabilitet over for syrer, alkalier, og salte, og er velegnet til en lang række pH-værdier.

Filmdannende og beskyttende effekter: Efter tørring, det danner en sej og gennemsigtig film for at beskytte underlaget og forhindre vandindtrængning og fordampning.

Ikke-giftig og ikke-irriterende: Det har god biokompatibilitet og er velegnet til medicin og fødevarer.

Justerbarhed: Ved at ændre graden af ​​substitution og molekylvægt, dens ydeevne kan justeres for at opfylde forskellige applikationskrav.
