Uburyo urumuri rwa hydroxypropyl methylcellulose ruterwa ahanini n'ingingo zikurikira:
1. Ubwiza bw'ibikoresho fatizo.
Icya kabiri, ingaruka zo kongera alkali.
3. Igipimo cy'imikorere
4. Igipimo cy'umusemburo
5. Ingaruka zo kugabanya ingaruka
Hari ibicuruzwa biba bifite ibicu nk'amata nyuma yo gushonga, bimwe biba bifite umweru usa n'amata, ibindi biba bifite umuhondo, ibindi bikaba bisobanutse neza… Kugira ngo ukemure ikibazo, hindura ukurikije ingingo zikurikira. Hari igihe aside asetiki ishobora kugira ingaruka zikomeye ku buryo urumuri rutangwa. Ni byiza gukoresha aside asetiki nyuma yo gushonga. Ingaruka nini ni ukumenya niba uburyo bwo gukora ibintu buvanze neza kandi niba igipimo cy'uburyo ibintu bihinduka (hari ibikoresho bifite ubushuhe n'ibikubiye muri byo ntibihindagurika, nk'umusemburo ukoreshwa mu kongera gukoresha). Mu by'ukuri, hari ibintu byinshi bigira ingaruka. Niba ibikoresho bihagaze neza kandi ababikora bakaba baratojwe neza, umusaruro ugomba kuba uhamye cyane. Uburyo urumuri rutangwa ntibuzarenga ± 2%, kandi uburyo bwo gusimbuza amatsinda agomba gukurikizwa bugomba kugenzurwa neza. Aho kugira ngo bibe bimwe, uburyo urumuri rutangwa neza nta kabuza.
Ibintu bigira ingaruka ku bucucike bwa Hydroxypropyl Methyl Cellulose
Hydroxypropyl methylcellulose ifite umuvuduko mwinshi ntishobora gukora cellulose nyinshi cyane binyuze mu gusukura umwuka no gusimbuza azote mu ikorwa. Muri rusange, ikorwa rya cellulose ifite umuvuduko mwinshi mu Bushinwa ntirishobora kugenzurwa. Ariko, niba igikoresho gipima ogisijeni gishobora gushyirwa mu gikoresho, ikorwa rya viscosity yacyo rishobora kugenzurwa mu buryo bw'ubukorano.
byakozwe. Byongeye kandi, ukurikije umuvuduko wo gusimbuza azote, biroroshye gukora ibintu bifite ubukana bwinshi uko imiterere y’ibintu imeze kose. Birumvikana ko urwego rwa polymerization y’ipamba itunganyijwe narwo ari ingenzi. Niba ibyo bidakora, bikora ukoresheje hydrophobic association. Hari ibintu bihuza muri aka gace mu Bushinwa. Ubwoko bw’ibintu bihuza ugomba guhitamo bigira ingaruka zikomeye ku mikorere y’umusaruro wa nyuma. Ogisijeni isigaye muri reactor itera kwangirika kwa cellulose no kugabanuka k’uburemere bwa molekile, ariko ogisijeni isigaye ni nke, igihe cyose molekile zangiritse zongeye guhuzwa, ntabwo bigoye gukora viscosity nyinshi. Ariko, igipimo cyo kuzura gifite byinshi byo gukora n’ingano ya hydroxypropyl. Inganda zimwe na zimwe zishaka kugabanya ikiguzi n’igiciro gusa, ariko ntizifuza kongera igipimo cya hydroxypropyl, bityo ubwiza ntibushobora kugera ku rwego rw’ibicuruzwa bisa byo mu mahanga. Igipimo cyo kubika amazi cy’umusaruro gifite isano ikomeye na hydroxypropyl, ariko mu buryo bwose bwo gukora reaction, inagena igipimo cyo kubika amazi, ingaruka za alkali, igipimo cya methyl chloride na propylene oxide, igipimo cya alkali no kubika amazi. Igipimo cy'ipamba itunganyijwe ni cyo kigena imikorere y'umusaruro.
