Hydroxypropyl Methylcellulose (HPMC) ni ifu yera itagira impumuro nziza, idafite uburozi. Nyuma yo gushonga neza mumazi, bizakora igisubizo kibonerana. Nibintu bitari ionic selulose ether bikozwe mubikoresho bisanzwe bya polymer binyuze murukurikirane rwo gutunganya imiti. Ifite ibiranga kubyimba, gufatira, gutatanya, emulisation, gukora firime, guhagarikwa, adsorption, gelation, ibikorwa byubutaka, kugumana ubushuhe no kurinda colloide.
Gusaba:
Amazi yogukoresha hamwe nubushobozi bwo kubyimba: irashobora gushonga mumazi akonje, kandi igakora igisubizo kibonerana.
Isenyuka mumashanyarazi kama: Kuberako irimo umubare munini wamatsinda ya hydrophobique methoxy, iki gicuruzwa gishobora gushonga mumashanyarazi amwe.
PH agaciro gahamye: Ubukonje bwibisubizo byamazi ya HPMC burahagaze neza murwego rwa PH agaciro 3.0-11.0.
Igikorwa cyo hejuru: HPMC igisubizo cyamazi gifite ibikorwa byubuso. Ifite emulisifike, irinda ubushobozi bwa colloid hamwe no gutuza ugereranije.
Ubushyuhe bwa Thermal: Iyo bushyutswe hejuru yubushyuhe runaka, igisubizo cyamazi ya HPMC kirashobora guhinduka, kubyara imvura, no gutakaza ubukonje. Ariko, yagiye ihinduka buhoro buhoro igisubizo cyambere nyuma yo gukonja.
Ibirimo ivu rike: HPMC ntabwo ari ionic, irashobora kwozwa namazi ashyushye mugihe cyo kwitegura kandi ikanozwa neza, bityo ivu ryayo rikaba rito cyane.
Kurwanya umunyu: Kubera ko iki gicuruzwa ari electrolyte itari ionic na polymeric, irahagaze neza mubisubizo byamazi byumunyu wicyuma cyangwa electrolytike kama.
Ingaruka yo gufata amazi: Kuberako HPMC ari hydrophilique kandi igisubizo cyayo cyamazi kiragaragara cyane. Irashobora kongerwamo minisiteri, gypsumu, irangi, nibindi kugirango igumane amazi menshi mubicuruzwa.
Kurwanya indwara ya mildew: Ifite imbaraga zo kurwanya indwara ya mildew, kandi ifite ubwiza bwimitsi mugihe cyo kubika igihe kirekire.
Amavuta: Kongera HPMC birashobora kugabanya coeffisiyoneri yo guterana no kunoza amavuta yibicuruzwa bya ceramic biva hanze nibicuruzwa bya sima.
Umutungo ukora firime: Irashobora kubyara flake ikomeye, yoroheje, ibonerana hamwe namavuta meza hamwe na ester irwanya.
Mubikoresho byubwubatsi, selile ya HPMC irashobora gukoreshwa nkigikoresho cyo kubika amazi nogusubiza inyuma sima kugirango sima ikorwe.
Nkibifatika, gukoresha HPMC muri plasta, gypsumu, ifu yuzuye cyangwa ibindi bikoresho byubwubatsi birashobora kunoza ikwirakwizwa ryabyo kandi bikongerera igihe cyo gukora.
Kugumana amazi kwayo birashobora kubuza paste guturika vuba nyuma yo gutwikira, kandi birashobora no kongera imbaraga zo gutwikira nyuma yo gukomera.
Uretse ibyo, imiti ya HPMC irashobora kandi gukoreshwa nk'iyongerera imbaraga za tile, marble, na plastike mu nganda zubaka.
Byongeye kandi, ifu ya HPMC ikoreshwa nkibyimbye, stabilisateur, emulifisiyeri, idasanzwe, hamwe nogutwara amazi mugukora izindi nganda, nka peteroli, imiti, ibikoresho, ibikoresho byo kubaka, kuvanaho amarangi, imiti yubuhinzi, wino, gucapa imyenda no gusiga irangi, ububumbyi, gukora impapuro, kwisiga, nibindi
Ipaki: 25 kgs / igikapu cyangwa nkuko ubisabye.
Ububiko: Bika ahantu hafite umwuka, humye.
Ibipimo byakozwe: Ibipimo mpuzamahanga.
