HPMC ikoreshwa mu ifu yuzuye ifu

1. Ibibazo bisanzwe mubifu

Kuma vuba:

Impamvu nyamukuru nuko ingano yifu ya calcium yivu yongeweho (nini cyane, ingano yifu ya calcium yivu ikoreshwa mumata ya putty irashobora kugabanuka muburyo bukwiye) ifitanye isano nigipimo cyo gufata amazi ya fibre, kandi nayo ifitanye isano no gukama y'urukuta.

Gukuramo no kuzunguruka:

Bifitanye isano nigipimo cyo gufata amazi, kandi ubukonje buke bwa selile bukunze guhura niki kibazo cyangwa umubare wongeyeho ni muto.

Gukuraho ifu yurukuta rwimbere rwifu:

Ingano yifu ya calcium yivu yongeweho (ingano yifu ya calcium yivu mumata ya putty ni nto cyane cyangwa ubuziranenge bwifu ya calcium yivu ni bike cyane, kandi ingano yifu ya calcium yivu mumata yifu ya pome igomba kwiyongera muburyo bukwiye) , kandi bifitanye isano nubunini bwa selile kandi Ubwiza burafitanye isano, bugaragarira mubipimo byo gufata amazi kubicuruzwa. Igipimo cyo gufata amazi ni gito, kandi ifu ya calcium yivu (okiside ya calcium iri mu ifu ya calcium yivu ntabwo ihindurwa neza na hydroxide ya calcium kugirango ihindurwe) ntabwo ihagije, ibyo bikaba biterwa.

Ifuro:

Ubushyuhe bwumye bwurukuta bujyanye nuburinganire, kandi bujyanye nubwubatsi.

Ingingo igaragara:

Ifitanye isano na selile, imitungo yayo ikora firime irakennye, kandi mugihe kimwe, umwanda uri muri selile ukora bike hamwe na calcium yivu. Niba reaction ikabije, ifu ya putty izagaragara muburyo bwibisigazwa byibishyimbo. Ntishobora gushyirwa kurukuta, kandi nta mbaraga zifatika icyarimwe. Mubyongeyeho, ibi bintu bibaho no kubicuruzwa nka carboxymethyl ivanze na selile.

Nyuma yo gukama, biroroshye kumeneka no guhinduka umuhondo:

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

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

Cellulose ikoreshwa nkibintu binini kandi bigumana amazi kuri putty. Bitewe na thixotropy ya selile ubwayo, kongeramo selile mu ifu ya putty nabyo biganisha kuri thixotropy nyuma yo kongeramo amazi muri putty. Iyi thixotropy iterwa no gusenya imiterere ihujwe neza yifu yifu. Iyi miterere ivuka kuruhuka kandi igacika intege mukibazo. Nukuvuga ko ububobere bugabanuka mukubyutsa, kandi ibishishwa bikira iyo bihagaze.

3. Niyihe mpamvu ituma putty iremereye mugikorwa cyo gusiba?

Muri iki kibazo, ubwiza bwa selile ikoreshwa muri rusange ni hejuru cyane. Bamwe mubakora bakoresha selile 200.000 kugirango bakore putty. Ibishishwa byakozwe muri ubu buryo bifite ubukonje bwinshi, bityo bikumva biremereye iyo bishaje. Ingano isabwa gushira kurukuta rwimbere ni kg 3-5, naho viscosity ni 80.000-100.000.

4. Kuki selile imwe ya viscosity selile yumva itandukanye mugihe cyizuba nizuba?

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 ko mugihe cyizuba, gerageza guhitamo ibicuruzwa bifite ubukonje bwinshi mugihe ukoresheje ibicuruzwa, cyangwa kongera selile.
