1. Incamake
Hydroxypropyl Methyl Cellulose (HPMC) ni ether idafite selile ionose ikozwe mubintu bisanzwe bya polymer - selile ikoresheje urukurikirane rw'imiti. Hydroxypropyl methylcellulose (HPMC) ni ifu itagira impumuro nziza, itaryoshye, idafite uburozi bwo kwisiga, ishobora gushonga mumazi akonje kugirango ibe igisubizo kibonerana kibonerana, gifite imirimo yo kubyimba, guhuza, gutatanya, kwigana, gukora firime, no guhagarika, adsorption, gelation, ibikorwa byubuso, kugumana ubushuhe nibintu birinda colloid.
Hydroxypropyl methylcellulose (HPMC) irashobora gukoreshwa mubikoresho byubaka, gutwikira, ibisigazwa byubukorikori, ububumbyi, ubuvuzi, ibiryo, imyenda, ubuhinzi, amavuta yo kwisiga n’itabi
2 、 Ibicuruzwa byihariye nibisobanuro Ibicuruzwa bigabanijwemo amazi akonje yo mu bwoko bwa S nubwoko busanzwe

3、imiterere y'ibicuruzwa
Ibyiza: Iki gicuruzwa nifu yera cyangwa yera-ifu, impumuro nziza, uburyohe kandiidafite uburozi.
Amazi yogukoresha hamwe nubushobozi bwo kubyimba: Iki gicuruzwa gishobora gushonga mumazi akonje kugirango kibe igisubizo kiboneye.
Isenyuka mumashanyarazi kama: Kuberako irimo umubare munini wamatsinda ya hydrophobique metoxyl, iki gicuruzwa gishobora gushonga mumashanyarazi amwe, kandi gishobora no gushonga mumashanyarazi avanze namazi nibintu kama.
Kurwanya umunyu: Kubera ko iki gicuruzwa ari polymer itari ionic, irahagaze neza mubisubizo byamazi yumunyu wicyuma cyangwa electrolytike kama.
Igikorwa cyo hejuru: Igisubizo cyamazi yiki gicuruzwa gifite ibikorwa byubuso, kandi gifite imikorere numutungo nka emulisation, kurinda colloid hamwe no gutuza ugereranije.
Ubushyuhe bwa Thermal: Iyo igisubizo cyamazi yiki gicuruzwa gishyushye ku bushyuhe runaka, gihinduka neza kugeza igihe kimeze (poly) ihindagurika, kuburyo igisubizo kibura ubukonje. Ariko nyuma yo gukonja, izahinduka igisubizo cyumwimerere. Ubushyuhe bwa gelation buterwa nubwoko bwibicuruzwa, ubwinshi bwumuti nigipimo cyubushyuhe.
PH itajegajega: Ubukonje bwumuti wamazi wibicuruzwa birahagaze murwego rwa PH3.0-11.0.
Ingaruka yo kugumana amazi: Kubera ko iki gicuruzwa ari hydrophilique, gishobora kongerwaho minisiteri, gypsumu, irangi, nibindi kugirango bigumane amazi menshi mubicuruzwa.
Kugumana imiterere: Ugereranije nizindi polymers zishonga amazi, igisubizo cyamazi yiki gicuruzwa gifite imiterere yihariye ya viscoelastic. Kwiyongera kwayo bifite ubushobozi bwo kugumana imiterere yibicuruzwa byakuwe mubutaka bidahindutse.
Amavuta: Kongera iki gicuruzwa birashobora kugabanya coeffisiyoneri yo guterana no kunoza amavuta yibicuruzwa byubutaka bwakuwe mubicuruzwa bya sima.
Ibikoresho byo gukora firime: Iki gicuruzwa gishobora gukora firime yoroheje, ikorera mu mucyo ifite ibikoresho byiza bya mashini, kandi ifite amavuta meza hamwe no kurwanya amavuta
4. Imiterere yumubiri nubumara
Ingano ya Particle: Igipimo cya mesh 100 kirenze 98.5%, igipimo cya mesh 80 ni 100%
Ubushyuhe bwa Carbone: 280 ~ 300 ℃
Ubucucike bugaragara: 0,25 ~ 0,70 / cm uburemere bwihariye 1.26 ~ 1.31
Ubushyuhe bwo guhindura ibara: 190 ~ 200 ℃
Ubushyuhe bwo hejuru: 2% igisubizo cyamazi ni 42 ~ 56dyn / cm
Gukemura: Kubora mumazi hamwe na solve zimwe, igisubizo cyamazi gifite ibikorwa byubutaka. Gukorera mu mucyo. Imikorere ihamye, kwikemurira guhinduka hamwe nubwiza, munsi yubukonje, niko gukomera.
HPMC ifite kandi ibiranga ubushobozi bwo kubyimba, kurwanya umunyu, gutuza kwa PH, gufata amazi, guhagarara neza, umutungo mwiza wo gukora firime, hamwe nubwinshi bwimisemburo ya enzyme, gutandukana no guhuriza hamwe.
5, intego nyamukuru
Urwego rwo mu nganda HPMC rukoreshwa cyane cyane mu gukwirakwiza umusaruro wa chloride polyvinyl, kandi niwo mufasha w’ingenzi mu gutegura PVC hakoreshejwe polymerisation ihagarikwa. Byongeye kandi, irashobora gukoreshwa nkibyimbye, stabilisateur, emulisiferi, idasanzwe, hamwe nogukomeza amazi mugukora ibindi bicuruzwa bya peteroli, gutwika, ibikoresho byubaka, kuvana amarangi, imiti yubuhinzi, wino, gucapa imyenda no gusiga amarangi, ububumbyi, impapuro , kwisiga, nibindi, umukozi ukora firime, nibindi. Gukoresha mubisigarira byubukorikori birashobora gutuma ibicuruzwa byabonetse bifite ibiranga uduce duto dusanzwe kandi tworoshye, uburemere bwihariye bukwiye hamwe nuburyo bwiza bwo gutunganya, bityo ahanini bigasimbuza inzoga za gelatine na polyvinyl nkizitatanya.
Uburyo butandatu bwo gusesa:
（1）. Fata amazi asabwa asabwa, uyashyire muri kontineri hanyuma uyashyuhe hejuru ya 80 ° C, hanyuma wongereho ibicuruzwa buhoro buhoro. Cellulose ireremba hejuru y’amazi ubanza, ariko igenda ikwirakwira buhoro buhoro kugirango ibe imwe. Igisubizo cyakonje mugihe gikurura.
（2）. Ubundi, shyushya 1/3 cyangwa 2/3 byamazi ashyushye hejuru ya 85 ° C, ongeramo selile kugirango ubone amazi ashyushye, hanyuma ushyiremo amazi asigaye asigaye, komeza ubyuke, hanyuma ukonje imvange yavuyemo.
（3）. Urushundura rwa selile rumeze neza, kandi rubaho nkutuntu duto duto muri porojeri iringaniye, kandi irashonga vuba iyo ihuye namazi kugirango ikore neza.
（4）. Buhoro buhoro kandi biringaniza selile mu bushyuhe bwicyumba, bikomeza kugeza igihe igisubizo kiboneye kiboneye.
