Ibibazo bikunze kubazwa bijyanye no gukoresha hydroxyproppopyl methylcellse

Ni ubuhe buryo bwo gukoresha hydroxypropyl methylcellse?
Byakoreshejwe cyane mu bikoresho byo kubaka, Gukora Amavuta, Ibisohokaga Singetike, Ububiko, Ubuvuzi, ibiryo, Amavuta, Ubuhinzi, Itabi n'izindi ngamba n'izita itabi n'izindi ngamba. HPMC irashobora kugabanywamo muri: Icyiciro cyo kubaka, amanota yibiribwa hamwe nicyiciro cya farumasi ukurikije intego. Kugeza ubu, ibyinshi mu bicuruzwa byo mu rugo ni urwego rwo kubaka. Mu rwego rwo kubaka, umubare w'ifu ya prowy ni munini, 90% ukoreshwa mu ifu ya prowder, kandi ahasigaye hakoreshwa kuri sima na kole.

Nubuhe buryo bwo gushonga hydroxypropyl methyl fibre?
1. Uburyo bushyushye butarimo amazi: Kubera ko HPMC idashonga mumazi ashyushye, HPMC irashobora gutatana rimwe mumazi ashyushye mugihe cyambere, hanyuma ashonga vuba iyo akonje.

2. Uburyo bwo kuvanga powder: Kuvanga ifu ya HPMC hamwe nibindi byinshi bya chimical pome, bivanaho neza, hanyuma ukabishozwa mumazi, kuko buri gitokiro gito cya HPMC, kandi kizashonga ako kanya, kandi bizashonga ako kanya iyo byujuje amazi.

Nigute wahitamo visosity ya hydroxyproppopyl methylcellse?
Hitamo virusi zitandukanye ukurikije porogaramu zitandukanye, gusaba ifu ya Putty: Urashobora guhitamo victoity ya 100.000, icy'ingenzi ni ugukomeza amazi neza. Gusaba minisiteri: Ibisabwa byinshi, viscosity yo hejuru, hitamo vicosity 150.000. Gushyira mu bikorwa kole: Ikeneye ibicuruzwa byihuse, viscosity yo hejuru, hitamo vicosity 200.000.

Nigute ushobora kumenya ubwiza bwa hydroxyproppopyl methylcellse?
Uwera: Nubwo cyera kitagaragaza niba HPMC yoroshye gukoresha, kandi niba umukozi wambaye urubyatsi yongewemo mubikorwa, bizagira ingaruka kumico yayo. Ariko, ibicuruzwa byinshi byiza bifite channene nziza.

Ibyiza: Guheza kwa HPMC muri rusange Mesh na Mesh 100, na Mesh 120 ni bike. HPMC nyinshi zakozwe muri Hebei ni mesh 80. Ibyiza byiza, nibyiza.

Gushyirwaho: Shyira hydroxyPropyl methylcellse (HPMC) mumazi kugirango ikore injyana ya Colloid, hanyuma urebe ko yakoherezwa. Ibijyanye na reactique ya reaction ni byiza, kandi reacttor itambitse cyane, ariko ntishobora kuvugwa ko ireme rya reactique riruta iy'umuyoboro utambitse, kandi haribintu byinshi byerekana ibicuruzwa.

Imbaraga zihariye: nini nini nini, nziza cyane. Uburemere bwihariye ni bunini, muri rusange kubera ko hydroxyPropylepyle iri hejuru, kandi hydroxyPropyl ibirimo ni hejuru, ihohoterwa ry'amazi ni ryiza.

Umubano hagati ya viscosiya nubushyuhe bwa hydroxypropyl methylcellse
Guhuza visosity ya HPMC ni kugereranya ubushyuhe butandukanye, ni ukuvuga, kubera ko ubushyuhe bugabanuka, ubwitonzi bwa vino yiyongera, kandi igisubizo cyacyo cyageragejwe ku bushyuhe bwa dogere 20. Mubikorwa bifatika, mubice bifite ubushyuhe bunini hagati yizuba nimbeho, byakagombye kumenya ko ubushyuhe bwo hasi bukoreshwa mu gihe cy'itumba, bikaba byiza kubaka.

Ni uruhe ruhare rwa HPMC mu ifu ya Putty?
Muri ifu ya PATDER, HPMC igira imirimo itatu: kubyimba, kugumana amazi no kubaka.

Kwinginga: Ubugari bushobora kwiyongera guhagarika, komeza umwerureko kandi uhamye, kandi urwanye ubwoba.

Kugumana amazi: kora ifu ya putty yumye buhoro, kandi ifashe reaction ya calcium ya Ash munsi yigikorwa cyamazi.

Kubaka: Ubugari bufite ingaruka zo gusiga, ishobora gutuma ifu ya LIPTY igira ibikorwa byiza. HPMC ntabwo yitabira imiti iyo ari yo yose kandi igira uruhare rufasha. Ongeraho amazi kuri powder ifu hanyuma uyishyire kurukuta ni reaction yimiti. Kubera gushinga ibintu bishya, fata ifu ya Putty kurukuta ku rukuta, uyasya mu ifu, hanyuma ukoreshe. Ntabwo izakora, kuko ibintu bishya (karubone ya calcium) byashizweho. ) hejuru.

Ibice byingenzi bya Ifu ya Ash Calcium ni: imvange ya ca (Oh) 2, Caociate ya Calcium yakozwe, mugihe cya HPMC gusa Calcium, kandi ntabwo yitabira reaction yose ubwayo.
