Icyerekezo cya viscosity ya hydroxypropyl methylcellulose ni indangagaciro ikomeye. Ubukonje ntibusobanura ubuziranenge. Ubukonje bwa selile HPMC biterwa nuburyo bwo gukora. Ibidukikije bitandukanye bigomba guhitamo selile HPMC hamwe na viscosities zitandukanye, ntabwo biri hejuru cyane ya viscosity ya selile HPMC, nibyiza! Ibikwiye nibyo.
Kugenzura Viscosity
1.Mu musaruro wa hydroxypropyl methylcellulose-yuzuye cyane, gusa vacuuming na nitrogen ntishobora kubyara selile nyinshi cyane. 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.
Gukoresha abakozi
2. 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.
Hydroxypropyl ibirimo
3. Umwuka wa ogisijeni usigaye muri reaktor utera kwangirika kwa selile hamwe nuburemere buke bwa molekile. Ariko, niba umwuka wa ogisijeni usigaye ari muto, mugihe cyose molekile zacitse zongeye guhuzwa, 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.
ibindi bintu
4. Igipimo cyo gufata amazi yibicuruzwa gifite umubano ukomeye na hydroxypropyl, ariko kandi kigena igipimo cyacyo cyo gufata amazi, ingaruka za alkalisation, igipimo cya methyl chloride na okiside ya propylene, hamwe na alkali yibanda kubikorwa byose. Ikigereranyo cyamazi nipamba inoze bigena imikorere yibicuruzwa.
