Hydroxypylthylthylcelllose, 28-30% methoxyl, 7-12% hydroxyl

Nkọwapụta "28-30% methoxyl" na "7-12% hydroxyyl" na-ezo aka na ogo nke dochie anya yaHydroxypylthththththylcelllose(Hpmc). Valueskpụrụ ndị a na-egosi oke nke polmer mbụ cellulose gbanwee site na methoxylyl dị iche iche.

1. 28-30% methoxyl:
   • Nke a na-egosi nke a, na nkezi, 28-30% nke otu hydroxy dị iche iche na cellulose molulu ndị otu methoxy. A na-ewebata otu methoxy (-Ch3) ka emelitere hydrophobity nke polymer.
2. 7-12% Hydroxyl:
   • Nke a na-egosi na, na nkezi, 7-12% nke otu hydroxy na celdrose molulu molulu na-ejikọ òtù. A na-ewebata ìgwè Hydroxyy (-Och2chohch3)

Ogo nke dochie Njirimara nke HPMC na arụmọrụ ya na ngwa dị iche iche. Ọmụmaatụ:

• Ọdịnaya Methoxy dị elu na-abawanye hydrophodicity polymer's na-emetụta mmiri solibility na akụrụngwa ndị ọzọ.
• Ọdịnaya Hydroxyl dị elu nwere ike ịkwalite mmiri sogbality na ihe nkiri na-akpụ akpụ nke HPMC.

Nkọwa ndị a dị mkpa na ịkwa akwa HPMC iji zute ihe ndị akọwapụtara na ụlọ ọrụ dị iche iche. Dịka ọmụmaatụ, na ụlọ ọrụ ọgwụ, nke ọkwa HPMC na ogo nke nnọchianya nwere ike ime ka profaịlụ ọgwụ na usoro mbadamba. N'ime ụlọ ọrụ owuwu, ọ nwere ike imetụta njigide mmiri na akụrụngwa adhesion nke ngwaahịa ciment.

Ndị na-emepụta ihe na-enwe ọtụtụ akara akara dị iche iche nke hpmc na ogo dị iche iche nke dochie mkpa nke ngwa dị iche iche. Mgbe ọ na-eji HPMC na usoro, ọ dị mkpa maka ndị na-eme ka ọkwa dị iche iche nke HPMC nke na njirimara akụrụngwa chọrọ maka ngwa ọrụ achọrọ.
