Ibyerekeye hydroxypropyl methylcellulose mugihe cyo gukoresha ifu ya putty

1. Ibibazo bisanzwe mubifu

[Kuma vuba] Ibi bifitanye isano ahanini nubunini bwifu ya calcium yivu yongeweho (nini cyane, irashobora kugabanya neza ingano yifu ya calcium yivu ikoreshwa mumata ya putty) hamwe nigipimo cyo gufata amazi ya hydroxypropyl methylcellulose (HPMC), kandi ifitanye isano nayo Ifitanye isano no gukama kurukuta.

[Uruhu no gutonda] Ibi bifitanye isano nigipimo cyo gufata amazi.Hydroxypropyl methylcellulose (HPMC) ifite ubukonje buke kandi ikunda guhura niki kibazo cyangwa umubare wongeyeho ni muto.

[Gukuramo ifu yo gukuramo ifu yimbere yimbere] Ibi bifitanye isano nubunini bwa pisiyumu ya calcium yivu yongeweho (ingano yifu ya calcium ya ivu muri formula ya putty ni nto cyane cyangwa ubwiza bwifu ya calcium yivu ni mike cyane, kandi ingano yivu ifu ya calcium muri formula yifu ya putty igomba kongerwa muburyo bukwiye) Muri icyo gihe, ijyanye kandi nubunini nubwiza bwa hydroxypropyl methylcellulose (HPMC), bigaragarira mu kigero cyo gufata amazi ku bicuruzwa.Igipimo cyo gufata amazi ni gito, kandi oxyde ya calcium iri mu ifu ya calcium yivu ya calcium ntabwo yinjizwa neza na calcium ya hydroxide ihindura hydration) igihe ntigihagije, cyatewe.

[Blistering] Ibi bifitanye isano nubushyuhe bwumye nuburinganire bwurukuta, kandi bifitanye isano nubwubatsi.

[Pin point zigaragara] Ibi bifitanye isano na selile, ifite imiterere mibi yo gukora firime, kandi n’umwanda uri muri hydroxypropyl methylcellulose (HPMC) wifata gake hamwe na calcium yivu.Niba reaction ikabije, ifu ya putty izagaragara tofu Slag leta.Ntishobora gushyirwa kurukuta, kandi nta mbaraga zifatika icyarimwe.Byongeye kandi, ibicuruzwa nka hydroxypropyl methylcellulose (HPMC) bivanze nitsinda rya carboxymethyl nabyo bigaragara muri ibi bihe.

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

.Niba ingano yifu ya calcium yivu yongewemo cyane, ubukana bwifu ya putty iziyongera nyuma yo gukama.Gusa gukomera nta guhinduka bizoroha byoroshye, cyane cyane birashoboka gucika iyo bikorewe 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 mugukangura, 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 murubu buryo bifite ubukonje bwinshi, bityo bizarohama mugihe cyo gusiba.ibyiyumvo bya.Ingano isabwa yo 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.
