Indangantego ya viscosity ya hydroxypropyl methylcellulose ni indangagaciro ikomeye.Ubukonje ntibusobanura ubuziranenge.Ubukonje bwa selile HPMC biterwa nuburyo bwo gukora.Ibidukikije bitandukanye bigomba guhitamo selile ya HPMC hamwe na viscosities zitandukanye, ntabwo biri hejuru cyane ya viscosity ya selile HPMC, nibyiza!Ibikwiye nibyo!
1. Kugenzura ibicucu
Hydroxypropyl methylcellulose ifite ubukana bwinshi ntishobora gutanga selile nyinshi cyane nukumara no gusimbuza azote mu musaruro.Muri rusange, umusaruro wa selile-viscosity selile mu Bushinwa ntushobora kugenzurwa.Ariko, niba metero ya ogisijeni ishobora gushyirwaho mu isafuriya, umusaruro wijimye wacyo urashobora kugenzurwa muburyo bwa artile.
2. Gukoresha umukozi wishyirahamwe
Byongeye kandi, urebye umuvuduko wo gusimbuza azote, biroroshye kubyara ibicuruzwa byijimye cyane nubwo sisitemu yaba ifite umuyaga mwinshi.Nibyo, urugero rwa polymerisation yipamba inoze nayo ni ngombwa.Niba ibyo bidakora, kora hamwe na hydrophobic association.Hano mu Bushinwa hari abakozi b'amashyirahamwe.Ni ubuhe bwoko bw'ishyirahamwe guhitamo bifite ingaruka zikomeye kumikorere yibicuruzwa byanyuma.
3. Ibirimo Hydroxypropyl
Umwuka wa ogisijeni usigaye muri reaktor utera kwangirika kwa selile no kugabanuka kwuburemere bwa molekile, ariko ogisijeni isigaye iba mike, mugihe cyose molekile zacitse zongeye guhura, ntabwo bigoye gukora ubukonje bwinshi.Nyamara, igipimo cyo kwiyuzuzamo gifite byinshi byo gukora nibiri muri hydroxypropyl.Inganda zimwe zishaka kugabanya gusa igiciro nigiciro, ariko ntizifuza kongera ibikubiye muri hydroxypropyl, bityo ubwiza ntibushobora kugera kurwego rwibicuruzwa bisa n’amahanga.
4. Ibindi bintu
Igipimo cyo gufata amazi yibicuruzwa gifitanye isano ikomeye na hydroxypropyl, ariko kubikorwa byose, bigena kandi igipimo cyayo cyo gufata amazi, ingaruka za alkalisation, igipimo cya methyl chloride na okiside ya propylene, kwibanda kuri alkali no kubika amazi.Ikigereranyo cya pamba inoze igena imikorere yibicuruzwa.
