Detergent Thickener Hydroxypropyl Methyl Cellulose Ether HPMC
Nnukwu viscosity HPMC hydroxypropyl methyl cellulose Ọkpụrụkpụ Maka ntụ ntụ putty:
1) Ọdịdị: HPMC bụ nonionic cellulose ether, ọcha grayish-acha ọcha ntụ ntụ ma ọ bụ granule, odorless na flavorless, soluble na mmiri oyi, glacial acetic acid, ethanol, methanol na propylene glycol, ubé soluble na acetone dabere n'ókè nke nnọchi, ọ fọrọ nke nta ka ọ ghara ịsacha ya na mmiri ọkụ, ethylene glycol na toluene. A na-agbaze HPMC na ngwakọta nke methanol 10% na 90% methylene chloride iji mepụta ngwọta colloidal.
2) Ngwọta nke HPMC nwere ọrụ elu, nghọta dị elu, na arụmọrụ kwụsiri ike. Mgbe ikpo ọkụ na ụfọdụ okpomọkụ, ngwọta na-aghọ urukpuru ma ọ bụ mepụta flocculent gel.
