Ibintu bigira ingaruka kumusaruro wa Hydroxypropyl Methyl Cellulose Viscosity!

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 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. Muri ako karere hari abakozi bashinzwe amashyirahamwe. Ni ubuhe bwoko bw'ishyirahamwe guhitamo bifite uruhare runini mubikorwa byibicuruzwa byanyuma.

3. Ibirimo Hydroxypropyl

Umwuka wa ogisijeni usigaye muri reaction utera kwangirika kwa selile no kugabanuka kwuburemere bwa molekile, ariko ogisijeni isigaye iba mike, 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.

4. Ibindi bintu

Igipimo cyo gufata amazi yibicuruzwa gifitanye isano nini na hydroxypropyl, ariko kubikorwa byose, bigena kandi igipimo cyacyo cyo gufata amazi, ingaruka za alkalisation, igipimo cya methyl chloride na okiside ya propylene, kwibanda kuri alkali no kubika amazi. Ikigereranyo cya pamba itunganijwe igena imikorere yibicuruzwa.
