Hydroxypropyl Methyl Cellulose Ether (HPMC)

Ibiranga:
① Hamwe no gufata neza amazi, kubyimba, rheologiya no gufatira hamwe, nicyo kintu cya mbere cyahisemo ibikoresho fatizo byo kuzamura ireme ryibikoresho byubaka nibikoresho byo gushushanya.
RangeImikoreshereze yagutse: kubera amanota yuzuye, irashobora gukoreshwa mubikoresho byose byubaka ifu. 
DosIbipimo bito: kg 2-3 kuri toni y'ibikoresho byo kubaka ifu kubera ubuziranenge.
Resistance Kurwanya ubushyuhe bwiza cyane: igipimo cyo gufata amazi yibicuruzwa rusange bya HPMC bizagabanuka hamwe no kwiyongera kwubushyuhe. Ibinyuranye, ibicuruzwa byacu birashobora gutuma minisiteri igira amazi menshi mugihe ubushyuhe bugeze kuri 30-40 ° C. Kubika amazi meza no mubushyuhe bwo hejuru mumasaha 48.
Ububasha bwiza: mubushyuhe bwicyumba, ongeramo amazi hanyuma ubireke muminota igera kuri 5, ureke bicare muminota mike, hanyuma ukangure gushonga. Iseswa ryihuta kuri PH8-10. Igisubizo gishyirwa mugihe kirekire kandi gifite ituze ryiza. Mubikoresho bivanze byumye, umuvuduko wo gutatanya no gushonga mumazi nibyiza cyane.

Uruhare rwa HPMC mumashanyarazi yumye

Ifu yumye yumye, methyl selulose ether igira uruhare mukubungabunga amazi, kubyimba no kunoza imikorere yubwubatsi. Imikorere myiza yo gufata neza amazi iremeza ko minisiteri itazatera umucanga, ifu no kugabanuka kwingufu kubera kubura amazi hamwe n’amazi meza ya sima atuzuye; Ingaruka yibyibushye yongerera cyane imbaraga zububiko bwa minisiteri itose, hamwe no kongeramo methyl selulose ether birashobora kugaragara neza Kunoza ububobere butose bwa minisiteri itose, kandi bikagira aho bihurira neza nubutaka butandukanye, bityo bikazamura imikorere ya minisiteri itose kurukuta no kugabanya imyanda.

Muri rusange, uko ubukonje buri hejuru, ningaruka nziza yo gufata amazi. Nyamara, uko ubukonje buri hejuru, niko uburemere bwa molekuline ya MC, hamwe no gukomera kwayo bizagabanuka ugereranije, ibyo bikaba bishobora kugira ingaruka mbi kumbaraga no mubikorwa bya minisiteri. Iyo hejuru yubukonje, niko bigaragara ingaruka zo kubyimba kuri minisiteri, ariko ntabwo ihwanye neza. Iyo hejuru yubukonje, niko amabuye atose azaba menshi. Mugihe cyo kubaka, bigaragarira nko kwizirika kuri scraper no gufatira hejuru kuri substrate. Ariko ntabwo ari byiza kongera imbaraga zimiterere ya minisiteri yonyine.

Imiterere yumubiri nubumashini:

1. Kugaragara: ifu yera cyangwa itari yera.
2. Ingano ya Particle: igipimo cya mesh 80-100 kirenze 98.5%; 80 mesh yatsinze igipimo ni 100%.
3. Ubushyuhe bwa Carbone: 280-300 ° C.
4. Ubucucike bugaragara: 0.25-0.70 / cm3 (mubisanzwe hafi 0.5 / cm3), uburemere bwihariye 1.26-1.31.
5. Ubushyuhe bwo guhindura ibara: 190-200 ° C.
6. Impagarara zubuso: 2% igisubizo cyamazi ni 42-56dyn / cm3.
7. Gushonga mumazi hamwe numuti umwe, nka Ethanol / amazi, propanol / amazi, trichloroethane, nibindi muburyo bukwiye. Ibisubizo byamazi biragaragara hejuru. Gukorera mu mucyo no gukora neza. Ibisobanuro bitandukanye byibicuruzwa bifite ubushyuhe butandukanye bwa gel, kandi guhinduka guhinduka hamwe nubwiza. Hasi ya viscosity, niko gukomera. Ibisobanuro bitandukanye bya HPMC bifite itandukaniro mubikorwa, kandi iseswa rya HPMC mumazi ntabwo rihindurwa nagaciro ka pH.
8. Hamwe no kugabanya ibirimo vitamine, ingingo ya gel iriyongera, amazi ya HPMC aragabanuka, kandi ibikorwa byo hejuru nabyo biragabanuka.
9.

Intego nyamukuru:

1. Ikoreshwa nka binder muri plaster, plaster, ifu yuzuye cyangwa ibindi bikoresho byubwubatsi kugirango utezimbere kandi wongere igihe cyakazi. Irashobora gukoreshwa nka paste tile, marble, imitako ya plastike, gushimangira paste, kandi irashobora no kugabanya urugero rwa sima. Imikorere igumana amazi ya HPMC irinda guhubuka guturika kubera gukama vuba nyuma yo kuyisaba, kandi ikongerera imbaraga nyuma yo gukomera.
2. Inganda zikora ubukorikori: Zikoreshwa cyane nkumuhuza mugukora ibicuruzwa byubutaka.
3. Irashobora gukoreshwa mugukuraho amarangi.
4. Icapiro rya wino: Ikoreshwa nkibyimbye, ikwirakwiza na stabilisateur mu nganda ya wino, kandi ifite ubwuzuzanye bwiza mumazi cyangwa kumashanyarazi kama.
5. Plastike: ikoreshwa nkigikorwa cyo kurekura, koroshya, amavuta, nibindi.
6. Polyvinyl chloride: Ikoreshwa nk'isaranganya mu gukora chloride polyvinyl, kandi ni yo mfashanyo nyamukuru yo gutegura PVC hakoreshejwe polymerisation ihagarikwa.
7. Abandi: Iki gicuruzwa nacyo gikoreshwa cyane mubikorwa byimpu, ibicuruzwa byimpapuro, kubungabunga imbuto nimboga ninganda zimyenda.

Uburyo bwo gushonga no gukoresha:

1. bivanze.
.
3. Gukoresha kuvanga byumye: Bitewe nubwiza buhebuje bwa HPMC, birashobora kuvangwa byoroshye na sima, ifu ya gypsumu, pigment nuwuzuza, nibindi, kandi bigera kubikorwa byifuzwa.

Gupakira, kubika no gutwara ibintu:

Gupakirwa mubipapuro bya pulasitiki cyangwa ikarito yuzuyeho imifuka ya pulasitike ya polyethylene, uburemere bwumufuka: 25kg. Ikidodo cyo kubika. Kurinda izuba, imvura nubushuhe mugihe cyo kubika no gutwara.
