Manyan dalilai da yawa da ke shafar riƙewar ruwa na hydroxypropyl methylcellulose

Hydroxypropyl methylcellulose (HPMC) wani ether ne wanda ba na ionic cellulose ba wanda aka yi daga cellulose polymer abu na halitta ta hanyar tsarin sinadarai. Farin foda ne mara wari, mara ɗanɗano kuma mara guba wanda ke kumbura zuwa cikin bayani koloidal bayyananne ko dan kadan a cikin ruwan sanyi. Yana da thickening, dauri, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface aiki, danshi-retaining da m colloid Properties. Ana iya amfani da hydroxypropyl methyl cellulose da methyl cellulose a cikin kayan gini, masana'antar fenti, resin roba, masana'antar yumbu, magani, abinci, yadi, aikin gona, sinadarai na yau da kullun da sauran masana'antu.

Riƙewar ruwa na hydroxypropyl methylcellulose samfurin HPMC da kansa yana shafar abubuwa masu zuwa:

1. Adadin hydroxypropyl methylcellulose HPMC ya kara da cewa mafi girma yawan adadin cellulose ether HPMC da aka kara, mafi girma yawan adadin ruwa kuma mafi kyawun tasirin ruwa. A cikin kewayon 0.25-0.6% ƙari, yawan riƙewar ruwa yana ƙaruwa da sauri tare da karuwar adadin adadin; lokacin da adadin adadin ya ƙara ƙaruwa, haɓakar haɓakar yanayin riƙe ruwa yana raguwa.

2. HPMC danko na hydroxypropyl methylcellulose Lokacin da danko na HPMC ya karu, yawan riƙewar ruwa kuma yana ƙaruwa; lokacin da danko ya kai wani matakin, haɓakar yawan riƙe ruwa yakan zama mai laushi.

3. Hydroxypropyl methylcellulose HPMC thermal gel zafin jiki High thermal gel zafin jiki, babban adadin riƙe ruwa; in ba haka ba, ƙarancin riƙe ruwa.

4. Hydroxypropyl methylcellulose HPMC homogeneity HPMC tare da uniform dauki, methoxyl da hydroxypropoxyl suna ko'ina rarraba, da kuma ruwa riƙe kudi ne high.
