Nigute ushobora kuvanga hydroxyproppopyl methylcellse?

HydroxyPropyl Methylcellsellse (HPMC) ni ukwiyongera cyane cyane mubwubatsi, imiti, ibiryo nibindi bice. Ifite uburimbane, gukora firime, guhungabana no guhindagura ibintu. Uburyo buvanze nukuri ni ngombwa kugirango imikorere myiza nibicuruzwa.

1. Imyiteguro
Imyiteguro yibintu: Witondere gukoresha ifu nziza ya HPMC. Hitamo viscosity ikwiye nibisobanuro ukurikije porogaramu yihariye.
Gutegura ibikoresho: Kwihuta-kwihuta, gutatana cyangwa kuvanga bisanzwe mubisanzwe bikoreshwa. Ibikoresho bigomba kuba bifite isuku kandi bidafite umwanda.
Guhitamo Solvent: HPMC isanzwe ikundwa mumazi akonje, ariko ibishushanyo mbonera cyangwa ibindi bitangazamakuru birashobora kandi gukoreshwa mubihe bimwe. Guhitamo neza ni ngombwa kugirango uvange n'imikorere y'ibicuruzwa byanyuma.

2. Kuvanga intambwe
Pretreatment: Ifu ya HPMC igomba kubanzizwa kugirango ukureho ibibyimba n'umwanda kugirango utandukanye.

Yongeyeho Solvent:
Uburyo bukonje butarimo amazi: Suka umubare ukenewe wamazi akonje muri mixer, tangira ukanatera, hanyuma usubiremo buhoro ongeraho ifu ya HPMC. Irinde kongeramo cyane icyarimwe kugirango wirinde agglomeration. Komeza ushikame kugeza ifu ikwirakwijwe rwose.
Uburyo buto bwo Gutandukanya Amazi: Kuvanga ifu ya HPMC hamwe namazi akonje amwe kugirango ahagarike, hanyuma ayisuke mumazi ashyushye agera kuri 70-90 ° C. Kangura umuvuduko mwinshi kugirango ushonge, hanyuma wongere amazi akonje kugirango ukonje kubushyuhe bwicyumba kugirango ubone igisubizo cyanyuma.

Gusenya no kubyimba:
Igihe HPMC yashonga mumazi, guhagarikwa birakorwa mbere. Mugihe igihe gishimishije cyiyongera kandi ubushyuhe bugabanuka, ubushyuhe bwiyongera buhoro buhoro kugeza igihe bishwe rwose. Igihe cyo kuvugurura gikunze gufata iminota 30 kugeza kumasaha menshi, bitewe na viscosity no kwibanda kuri HPMC.
Kugirango usenye bwuzuye, igisubizo kirashobora kwemererwa guhagarara mugihe runaka (nkiyi ijoro ryose) kugirango ugere kuri vino nziza.

Guhindura no Guhindura:

Nibiba ngombwa, imitungo yigisubizo irashobora guhinduka wongeyeho ibindi bintu (nko kubungabunga, ibibanyi, nibindi). Kwiyongera bigomba gukorwa buhoro no kwemeza isaranganya rimwe.
Kuzungura no gufata nabi:

Gukuraho ibice bidatinze hamwe nudusimba, akayunguruzo cyangwa kwambuka birashobora gukoreshwa. Kuzuyemo birashobora gukuraho umwanda, mugihe impaka zifasha kubona igisubizo gihamye.

3. INTEGO
Ubwiza bw'amazi n'ubushyuhe: Ubwiza bwamazi bufite uruhare runini mugusenya HPMC. Birasabwa gukoresha amazi yoroshye cyangwa amazi adapfunyitse kugirango wirinde ifaranga ryatewe na calcium na magnesium ions mumazi akomeye. Ubushyuhe bwinshi cyangwa buke cyane buzagira ingaruka kubibazo byonyine no kwinuba bya HPMC kandi bigomba kugenzurwa murwego rukwiye.

Umuvuduko wihuta nigihe: hejuru cyane umuvuduko ukabije urashobora kumenyekanisha umwuka munini na bubbles; Hafi cyane umuvuduko ukabije urashobora gutera kuvanga. Ibipimo byungutse bigomba guhinduka ukurikije ibikoresho byihariye na formulaire.

Irinde agglomeration: Iyo wongeyeho ifu ya HPMC, igomba kongeraho buhoro kandi kurigandukira, kandi ikagumaho gukangurira kugirango yirinde gutera imbere. Ifu irashobora kugenwa hamwe namazi akonje cyangwa umukozi wo kurwanya akantu ashobora gukoreshwa.

Kubika no gukoresha: Igisubizo cya HPMC cyateguwe kigomba kubikwa mubikoresho bifunze kugirango birinde urumuri nubushyuhe bwo hejuru. Iyo ibitswe kuva kera, leta yumutingito igomba gusuzumwa buri gihe kugirango wirinde imvura cyangwa kwangirika.

Kuvanga hydroxyproppopyl methylcellse isaba kugenzura neza nuburyo bwo gukora kugirango bikemure imikorere n'ingaruka mubikorwa byanyuma. Binyuze mu guhitamo ibikoresho neza, gukoresha neza, guhuza uburyo ningamba, ibisubizo byinshi bya HPMC birashobora kwitegura kuzuza ibikenewe mubice bitandukanye bya porogaramu. Mubyukuri mubikorwa, guhinduka no guhitamo bigomba gukorwa ukurikije ibihe byihariye kugirango ubone ingaruka nziza.
