1 Ni ubuhe buryo bukoreshwa bwa selile ether HPMC?
HPMC ikoreshwa cyane mubikorwa bya minisiteri yubwubatsi, irangi rishingiye kumazi, resinike yubukorikori, ububumbyi, ubuvuzi, ibiryo, imyenda, amavuta yo kwisiga, itabi, nizindi nganda. Igabanijwemo ibyiciro byubwubatsi, urwego rwibiryo, urwego rwa farumasi, urwego rwinganda rwa PVC nicyiciro cyimiti ya buri munsi.
2 Ni ubuhe bwoko bwa selile?
Cellulose isanzwe ni MC, HPMC, MHEC, CMC, HEC, EC
Muri byo, HEC na CMC bikoreshwa cyane mu gutwikira amazi;
CMC irashobora kandi gukoreshwa mubutaka, mumirima ya peteroli, ibiryo nibindi bice;
EC ikoreshwa cyane mubuvuzi, ifeza ya elegitoroniki nizindi nzego;
HPMC igabanijwemo ibintu bitandukanye kandi ikoreshwa mubutaka, ubuvuzi, ibiryo, inganda za PVC, ibikomoka ku miti ya buri munsi nizindi nganda.
3Ni irihe tandukaniro riri hagati ya HPMC na MHEC mubisabwa?
Imiterere yubwoko bubiri bwa selile irasa cyane, ariko ubushyuhe bwo hejuru bwa MHEC nibyiza, cyane cyane mugihe cyizuba iyo ubushyuhe bwurukuta buri hejuru, kandi imikorere yo gufata amazi ya MHEC iruta iya HPMC mubihe byubushyuhe bwinshi .
4 Nigute dushobora gusuzuma gusa ubuziranenge bwa HPMC?
1) Nubwo umweru udashobora kumenya niba HPMC yoroshye kuyikoresha, kandi niba ibikoresho byera byongewe mubikorwa byo kubyara umusaruro, ubwiza buzagira ingaruka, ariko ibicuruzwa byinshi byiza bifite umweru mwiza, ushobora gucirwa urubanza ukurikije uko bigaragara.
2) Itumanaho ryoroheje: Nyuma yo gushonga HPMC mumazi kugirango ikore colloid ibonerana, reba itumanaho ryayo. Nibyiza kohereza urumuri, ibintu bitangirika bihari, kandi ubuziranenge nibyiza.
Niba ushaka kumenya neza ubwiza bwa selile, uburyo bwizewe ni ugukoresha ibikoresho byumwuga muri laboratoire yabigize umwuga yo kwipimisha. Ibipimo nyamukuru byipimisha birimo ubukonje, igipimo cyo gufata amazi, nibirimo ivu.
5 Uburyo bwo kumenya ububobere bwa selile?
Viscometer isanzwe kumasoko yimbere ya selile ni NDJ, ariko kumasoko mpuzamahanga, abayikora batandukanye bakoresha uburyo butandukanye bwo gupima ibibyimba. Ibisanzwe ni Brookfeild RV, Hoppler, kandi hariho nuburyo butandukanye bwo gutahura, bugabanijwemo 1% nigisubizo cya 2%. Viscometero zitandukanye hamwe nuburyo butandukanye bwo gutahura akenshi bivamo itandukaniro inshuro nyinshi cyangwa inshuro nyinshi mubisubizo byubusa.
6Ni irihe tandukaniro riri hagati yubwoko bwa HPMC nubwoko bushushe?
Ibicuruzwa bya HPMC ako kanya bivuga ibicuruzwa bikwirakwira vuba mumazi akonje, ariko tugomba kumenya ko gutatanya bidasobanura guseswa. Ibicuruzwa ako kanya bivurwa na glyoxal hejuru hanyuma bikwirakwizwa mumazi akonje, ariko ntibitangira guhita bishonga. , ubwo rero viscosity ntabwo itangwa ako kanya nyuma yo gutatana. Umubare munini wokuvura hejuru ya glyoxal, niko gutatanya byihuse, ariko buhoro buhoro bwijimye, niko glyoxal iba ntoya, naho ubundi.
7 selile hamwe na selile yahinduwe
Noneho hari byinshi byahinduwe na selile hamwe na selile selile ku isoko, none guhindura no guhuza ni iki?
Ubu bwoko bwa selile bukunze kugira ibintu selile yumwimerere idafite cyangwa ikazamura bimwe mubintu byayo, nka: anti-kunyerera, kongera igihe cyo gufungura, kongera ahantu hasakara kugirango bitezimbere ubwubatsi, nibindi, ariko, twakagombye kumenya ko ibigo byinshi koresha kandi selulose ihendutse isambana kugirango igabanye ibiciro yitwa selile selile cyangwa selile yahinduwe. Nkumuguzi, gerageza gutandukanya kandi ntugashukwe. Nibyiza guhitamo ibicuruzwa byizewe mubirango binini ninganda nini.
