Isano iri hagati yubushuhe nubushyuhe bwa Hydroxypropyl Methylcellulose (HPMC)

(1) KwemezaHPMCviscosity: Igicuruzwa cyumye gitegurwa mumuti wamazi ufite uburemere bwa 2 ° C, kandi bipimwa nubwoko bwa NDJ-1 buzunguruka;

(2) Kugaragara kwibicuruzwa ni ifu, kandi ibicuruzwa ako kanya byongeweho na "s" mwizina ryikirango.

Nigute ushobora gukoresha hydroxypropyl methylcellulose?

Yongeweho muburyo butaziguye. Ubu buryo nuburyo bworoshye kandi butwara igihe gito. Intambwe zihariye ni:

.

2. Komeza kubyutsa umuvuduko muke, hanyuma uhindure buhoro buhoro ibicuruzwa mubikoresho bikurura;

3. Komeza kubyutsa kugeza ibice byose byashizwemo;

4. Ongeramo amazi akonje ahagije kandi ukomeze kubyutsa kugeza ibicuruzwa byose bishonge burundu (gukorera mu mucyo biragaragara ko byiyongereye);

5. Noneho ongeramo ibindi bikoresho muri formula.

Tegura inzoga za nyina kugirango ukoreshwe: Ubu buryo nugutegura ibicuruzwa mubinyobwa byababyeyi bifite umurego mwinshi, hanyuma ukabyongera kubicuruzwa. Akarusho nuko ifite ihinduka ryinshi kandi irashobora kongerwaho muburyo butaziguye kubicuruzwa byarangiye. Intambwe nimwe (1-3) muburyo bwo kongeramo. Ibicuruzwa bimaze gutose, reka bihagarare kugirango ubukonje busanzwe bushonga, hanyuma ubyuke neza mbere yo kubikoresha. Twabibutsa ko imiti igabanya ubukana igomba kongerwamo inzoga za nyina vuba bishoboka.

Gukoresha kuvanga byumye: Nyuma yo gukama neza kuvanga ibicuruzwa byifu nibikoresho bya poro (nka sima, ifu ya gypsumu, ibumba ryibumba, nibindi), ongeramo amazi akwiye, hanyuma ubikate neza hanyuma ubyereke kugeza ibicuruzwa bishonge burundu.

Iseswa ryibicuruzwa bikonjesha amazi akonje: ibicuruzwa bikonjesha amazi akonje birashobora kwongerwaho mumazi akonje kugirango bisenywe. Nyuma yo kongeramo amazi akonje, ibicuruzwa bizarohama vuba. Nyuma yo gutose mugihe runaka, tangira kubyutsa kugeza bishonge burundu.

Kwirinda mugihe utegura ibisubizo

(1) Ibicuruzwa bitavuwe hejuru (usibye hydroxyethyl selulose) ntibishobora gushonga mu mazi akonje;

.

(3) Agaciro pH k'ubushyuhe bw'amazi n'amazi bifitanye isano ikomeye no gusesa ibicuruzwa, kandi hagomba kwitabwaho byumwihariko;

.

(5) Mugihe gishoboka, ongeramo imiti igabanya ubukana mbere;

.

(7) Ibicuruzwa byavuwe ako kanya ntibishobora gukoreshwa mubiribwa cyangwa imiti yimiti.
