Icyiciro cyo Kubaka Icyiciro （HPMC） Hydroxypropyl methyl selulose
Amabuye ya sima avanze yahindutse igice cyingenzi cyinganda za minisiteri ku isi kandi zigira uruhare rukomeye kubera kuzamura isoko no gushyigikira politiki yigihugu.Mugutezimbere minisiteri, selile ether numurwanashyaka wa animportant.
Ubusanzwe minisiteri isanzwe isaba ubukungu murwego rwa sima ruto, ariko ibisabwa mubikorwa byayo no gutera imashini biracyari hejuru, bityo gutondekanya umucanga ninyongera ni ngombwa.Mubyongeyeho, gukoresha imashini bizahinduka imyumvire yiterambere yiterambere-ivanze na minisiteri, selile ether izakora imashini ishoboka.
Ibiranga ibicuruzwa
Kongera amazi.
Kugumana amazi menshi, kongera igihe cyo gukora cyibikoresho, kunoza imikorere yakazi, kwirinda ibintu byo guhonda, no gufasha kunoza imbaraga za mashini yibikoresho.
Kunoza imikorere yimikorere, gutanga amavuta nuburyo bumwe, kugirango ubuso bwibikoresho byoroshye guhanagura, bityo kunoza imikorere yubwubatsi, no kunoza uburyo bwo kurwanya ibishishwa.
Kunoza ubutinganyi, no kunoza imitekerereze ihagaze.
HPMC kumatafari
Amabati yububiko afite imikorere ihanitse kandi ikora neza iyo ikozwe kuri substrate zitandukanye.Kurwanya skid hamwe nigihe cyo gufungura neza nurufunguzo rwibisabwa byiza.
HPMC yo gushiraho urukuta
HPMC ntabwo ari ionic selulose ether ikozwe muri fibre naturel ya fibre isanzwe yo gutunganya imiti.Nimpumuro nziza, idafite uburyohe kandi idafite uburozi ifu yera, irashobora gushonga mumazi asanzwe kugirango ibe igisubizo kibonerana kibonerana hamwe nuburyo bwo kubyimba, guhambira, gutatanya, emulisitiya, gutwikira firime, guhagarika, gukuramo, gukuramo, kubika amazi no kurinda colloid.
selulose ethers itanga ibintu byiza bikurikira kuri minisiteri:
Ubushobozi bwiza bwo guhanagura ubushobozi kuri substrate
Ubushobozi bwo gufata neza amazi
Imikorere myiza yo gutera no kuvoma
Gutezimbere sima muguhuza imbaraga
Ibisobanuro ku bicuruzwa
) muburyo budashonga mumazi ashyushye, Ethylene glycol na toluene.HPMC ishonga mu ruvange rwa 10% methanol na 90% methylene chloride kugirango bibe ibisubizo bya colloidal.
2) Igisubizo cya HPMC gifite ibikorwa byubuso, gukorera mu mucyo, no gukora neza.Iyo ashyutswe mubushyuhe runaka, igisubizo gihinduka ibicu cyangwa gukora gel flocculent.Nyamara, igisubizo cyongeye kugaragara nyuma yo gukonja.Ubwoko butandukanye bwa HPMC bufite ubushyuhe butandukanye.Gukemura biratandukanye nubwiza.Hasi ya viscosity, nubushobozi bwo hejuru ifite.Ubwoko butandukanye bwa HPMC buratandukanye mubintu bimwe na bimwe kandi gukomera kwamazi ntabwo bigira ingaruka kuri pH.
3) Ingano y'ibice: igipimo cya 100% muri 80 mesh.
4) Ubucucike bugaragara: 0.25-0.70 g / mL (mubisanzwe hafi 0.5 g / mL), ubucucike bwihariye 1.26-1.31mL.
5) Guhindura amabara ubushyuhe: 190-200 ° C;Ubushyuhe bwa Carbone: 280-300 ° C.
6) Ubushyuhe bwo hejuru: 42-56 dyn / cm (igisubizo cyamazi 2%).
7) Ibikoresho byinshi biri muri HPMC, ubushyuhe bwo hasi bwa gelation, hamwe no gukomera kwinshi mumazi no mubikorwa byo hejuru.
8) HPMC ifite ibindi bintu biranga, urugero, kubyimba umutungo, pH ihagaze neza, kubika amazi, umutungo mwiza wo gukora firime, gutatanya neza hamwe nubushobozi bwo gufatira hamwe.
