Gukemura ibibazo bisanzwe biterwa na selile mugukoresha ifu ya putty

1. Ibibazo bisanzwe mubifu

Kuma vuba biterwa ahanini nubunini bwifu 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 umwuma w'urukuta.

Gukuramo no gutembera bifitanye isano nigipimo cyo gufata amazi, byoroshye kugaragara mugihe ubwiza bwa selile ari buke cyangwa ubwinshi bwinyongera ni buto.

Gukuraho ifu yo gukuramo urukuta rwimbere ifu ifitanye isano nubunini bwifu ya calcium yivu yongewemo (ingano yifu ya calcium yivu yivu mumata ya putty ni nto cyane cyangwa ubuziranenge bwifu ya calcium yivu iri hasi cyane, kandi ingano yivu ifu ya calcium mumata yifu ya putty igomba kongerwa muburyo bukwiye). Muri icyo gihe, bifitanye isano kandi nubunini nubwiza bwa selile, bigaragarira mu kigero cyo gufata amazi ku bicuruzwa. 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.

Kubira ifuro bifitanye isano nubushyuhe bwumye nuburinganire bwurukuta, kandi bifitanye isano nubwubatsi.

Kugaragara kwa pinpoints bifitanye isano na selile, ifite imiterere mibi yo gukora film. Muri icyo gihe, umwanda uri muri selile ukora bike hamwe na calcium ya ivu. 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.

Crater na pinholes biragaragara. Ibi biragaragara ko bifitanye isano nubushyuhe bwamazi ya hydroxypropyl methylcellulose yumuti wamazi. 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 ivu.

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

Cellulose ikoreshwa nkibintu binini kandi bigumana amazi muri 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 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 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 guhitamo ibicuruzwa bifite ubukonje bwinshi mugihe ukoresheje ibicuruzwa mugihe cyizuba, cyangwa kongera umubare wa selile, no guhitamo ibicuruzwa bifite ubushyuhe bwinshi bwa gel. Gerageza kudakoresha methyl selulose mugihe cyizuba. Ubushyuhe bwa gel buri hagati ya dogere 55, niba ubushyuhe buri hejuru gato, ubwiza bwabwo buzagira ingaruka cyane.
