Ibintu bigira ingaruka ku ikorwa ry'ubushyuhe bwa Hydroxypropyl Methylcellulose

Igipimo cy'ubukana bwahydroxypropyl methylcelluloseni igipimo cy'ingenzi cyane. Ubwinshi bw'ibice ntabwo bugaragaza ubuziranenge. Ubwinshi bw'ibice bya selulose HPMC biterwa n'uburyo bikorwamo. Ahantu hatandukanye ho gukoreshwa hagomba guhitamo selulose HPMC ifite ubunini butandukanye, ntabwo ari uko selulose HPMC ifite ubunini bwinshi, ahubwo ni byiza kurushaho! Igikwiye ni cyo gikwiye √

Kugenzura ubucucike

1. Hydroxypropyl methylcellulose ifite umuvuduko mwinshi ntishobora gukora cellulose nyinshi cyane gusa binyuze mu gusukura no gusimbuza azote. Muri rusange, umusaruro wa cellulose ifite umuvuduko mwinshi mu Bushinwa ntushobora kugenzurwa. Ariko, niba igikoresho gipima ogisijeni gishobora gushyirwa mu gikoresho, umusaruro wa viscosity ushobora kugenzurwa mu buryo bw'ubukorano.

Gukoresha abakozi bashinzwe associative

2. Byongeye kandi, ukurikije umuvuduko wo gusimbuza azote, kandi icyarimwe, biroroshye cyane gukora ibintu bifite ubukana bwinshi uko ikoranabuhanga ryaba rimeze kose. Birumvikana ko urwego rwa polymerization y'ipamba ryatunganyijwe narwo ari ingenzi. Niba ibyo bidakora, bikore ukoresheje hydrophobic association. Hariho associative agents zo mu rugo muri uru rwego. Ubwoko bwa associative agent yatoranijwe bugira ingaruka zikomeye ku mikorere y'umusaruro wa nyuma.

Ibikubiye muri Hydroxypropyl

3. Ogisijeni isigaye muri reactor ituma cellulose igabanuka ndetse n'uburemere bwa molekile bugabanuka, ariko ogisijeni isigaye ni nke. Ntabwo bigoye gukora viscosity nyinshi igihe cyose molekile zacitse zihujwe. Ariko, igipimo cy'amazi ahagije nacyo gifitanye isano rya bugufi n'ingano ya hydroxypropyl. Inganda zimwe na zimwe zishaka kugabanya ikiguzi n'igiciro gusa, kandi ntizifuza kongera ingano ya hydroxypropyl, bityo ubwiza ntibushobora kugera ku rwego rw'ibicuruzwa bisa n'ibyo mu mahanga.

4. Igipimo cyo kubika amazi k'umusaruro gifitanye isano rikomeye na hydroxypropyl, ariko mu buryo bwose bwo gukora, kinagena igipimo cyo kubika amazi, ingaruka za alkali, igipimo cya methyl chloride na propylene oxide, hamwe n'ingano ya alkali. Kandi igipimo cy'amazi ku ipamba itunganyijwe ni cyo kigena imikorere y'umusaruro.
