Gịnị bụ HPMC maka gypsum plasta?

Hydroxypyl Methylcelllose (HPMC) na-arụ ọrụ dị mkpa na ịkwalite arụmọrụ na akụrụngwa nke gypsum plasta. Ihe mgbakwunye a dị iche iche na-arụ ọrụ dị iche iche, na-enye aka n'ọrụ ọrụ, adhesion, njigide mmiri, na ogo nke plasta ahụ.

Ọmụma kemịkal na akụrụngwa:
HPMC bụ ezinụlọ nke eyers nke eyers, nke a na-enweta site na cellose, onye na-eme polmer na-achọta na mgbidi cells.

Mgbanwe a na-enye ihe pụrụ iche na HPMC, gụnyere mmiri solbilition, gelition ike, na njiri maramara.

Usoro imeputa:
Mmepụta HPMC gụnyere ọtụtụ usoro. Na mbu, a na-amịpụta sellose site na ebe osisi dị ka osisi pulp ma ọ bụ owu. Nke a bụ, cellulose a na-enwe ogo, ebe hydroxypropyyl nathy na methy na Methym na Hydroxy na-arụ ọrụ na-arụ ọrụ molecuse. Enwere ike ịchịkwa ogo nke otu ndị a n'oge njikọta, na-emetụta akụrụngwa nke ngwaahịa HPMC ikpeazụ.
