Kubyerekeranye na hydroxypropyl methylcellulose mugukoresha ifu ya putty

1. Ibibazo bisanzwe mubifu

byumye vuba

Ibi bifitanye isano ahanini nubunini bwifu ya calcium yivu yongeweho (nini cyane, ingano yifu ya calcium yivu ikoreshwa mumata ya putty irashobora kugabanuka muburyo bukwiye) hamwe nigipimo cyo gufata amazi ya hydroxypropyl methylcellulose (HPMC), kandi nayo ifitanye isano gukama k'urukuta bijyanye.

Gukuramo no kuzunguruka

Ibi bifitanye isano nigipimo cyo gufata amazi, byoroshye kugaragara mugihe ubwiza bwa hydroxypropyl methylcellulose (HPMC) buri hasi cyangwa umubare wongeyeho ni muto.

Gukuramo ifu yinkuta yimbere imbere

Ibi bifitanye isano nubunini bwifu ya calcium yivu (ingano yifu ya calcium yivu yivu mumata ya putty ni nto cyane cyangwa ubuziranenge bwifu ya calcium yivu ni bike cyane, kandi ingano yifu ya calcium yivu mumata yifu yifu igomba kuba byiyongereye bikwiye), kandi bifitanye isano nubunini bwa hydroxypropyl methyl Ingano ya selile fatizo (HPMC) ifitanye isano nubwiza, bugaragarira mubipimo byo gufata amazi kubicuruzwa.Igipimo cyo gufata amazi ni gito, kandi igihe cyifu ya calcium yivu (okiside ya calcium mu ifu ya calcium yivu ntabwo ihindurwa neza na hydroxide ya calcium) ntabwo ihagije., byatewe.

bubbling

Ibi bifitanye isano nubushyuhe bwumye nuburinganire bwurukuta, kandi bifitanye isano nubwubatsi.

pin point

Ibi bifitanye isano na selile, ifite imiterere mibi yo gukora film.Muri icyo gihe, umwanda uri muri hydroxypropyl methylcellulose (HPMC) ukora bike hamwe na calcium ya ivu.Niba reaction ikabije, ifu ya putty izaba imeze ibisigazwa byibishyimbo.Ntishobora gushyirwa kurukuta, kandi nta mbaraga zifatika icyarimwe.Byongeye kandi, ibicuruzwa nka hydroxypropyl methylcellulose (HPMC) bivanze nitsinda rya carboxymethyl nabyo bigaragara muri ibi bihe.

Ibirunga na pinhole biragaragara

Ibi biragaragara ko bifitanye isano nubushyuhe bwamazi ya hydroxypropyl methylcellulose (HPMC) igisubizo cyamazi.Amazi yamazi ya hydroxyethyl yumuti wamazi ntabwo agaragara.Byaba byiza gukora imiti irangiye.

Nyuma yo gushira, biroroshye kumeneka no guhinduka umuhondo

Ibi bifitanye isano no kongeramo ifu nyinshi ya ivu-calcium.Niba ingano yifu ya calcium-calcium yongeweho cyane, ubukana bwifu ya putty iziyongera nyuma yo gukama.Niba ifu ya putty idafite ihinduka, izacika byoroshye, cyane cyane iyo ikorewe imbaraga ziva hanze.Bifitanye isano kandi nibirimo byinshi bya okiside ya calcium mu ifu ya calcium ya calcium.

2. Kuki ifu ya putty iba yoroheje nyuma yo kongeramo amazi?

Hydroxypropyl methylcellulose (HPMC) ikoreshwa nkumubyimba kandi ugumana amazi mumavuta.Bitewe na thixotropy ya hydroxypropyl methylcellulose (HPMC), hydroxypropyl methylcellulose mu ifu ya putty Kwiyongera kwa HPMC byanateje thixotropy nyuma yo kongeramo amazi muri putty.Iyi thixotropy iterwa no gusenya imiterere ihuza ibice bigize ifu ya putty.Iyi miterere ivuka kuruhuka kandi igacika intege mukibazo.Nukuvuga ko ububobere bugabanuka mukubyutsa, kandi ibishishwa bikira iyo bihagaze.

3. Niyihe mpamvu ituma putty iremereye mugihe cyo gusiba?

Muri iki gihe, ubukonje bwa hydroxypropyl methylcellulose (HPMC) busanzwe bukoreshwa ni hejuru cyane, kandi nababikora bamwe bakoresha amafaranga 200.000 yo gukora putty.Ibishishwa byakozwe muri ubu buryo bifite ubukonje bwinshi, bityo bizarohama mugihe cyo gusiba.ibyiyumvo bya.Ingano isabwa gushira kurukuta rwimbere ni kg 3-5, naho viscosity ni 80.000-100.000.

4. Kuki wumva ko ubwiza bwa hydroxypropyl methylcellulose (HPMC) hamwe nubwiza bumwe butandukanye mugihe cyizuba nimpeshyi?

Bitewe nubushyuhe bwumuriro wibicuruzwa, ubwiza bwa putty na minisiteri bizagenda bigabanuka buhoro buhoro hamwe no kwiyongera kwubushyuhe.Iyo ubushyuhe burenze ubushyuhe bwa gel bwibicuruzwa, ibicuruzwa bizagwa mumazi bikabura ubukonje.Ubushyuhe bwicyumba mugihe cyizuba muri rusange buri hejuru ya dogere 30, bitandukanye cyane nubushyuhe bwimbeho, bityo ubukonje buri hasi.Birasabwa guhitamo ibicuruzwa bifite ubukonje bwinshi mugihe ukoresheje ibicuruzwa mugihe cyizuba, cyangwa kongera umubare wa hydroxypropyl methylcellulose (HPMC), no guhitamo ibicuruzwa bifite ubushyuhe bwinshi bwa gel.
