Ibibazo biterwa na selile mugukoresha ifu ya putty nibisubizo byabyo

1. Ibibazo bisanzwe mubifu

Kuma vuba: Ibi biterwa ahanini nubunini bwifu ya calcium ya lime yongeweho (nini cyane, ingano yifu ya calcium ya lime ikoreshwa mumata ya putty irashobora kugabanuka muburyo bukwiye) ifitanye isano nigipimo cyo gufata amazi ya fibre, kandi nayo bijyanye no gukama k'urukuta.

Kuramo no kuzunguruka.Ibi bifitanye isano nigipimo cyo gufata amazi, byoroshye kugaragara mugihe ubwiza bwa selile ari buke cyangwa umubare winyongera ukaba muto.

Gukuramo ifu yifu yimbere yimbere: Ibi bifitanye isano nubunini bwifu ya calcium yivu yongeweho (ingano yifu ya calcium ya ivu mumata ya putty ni nto cyane cyangwa ubwiza bwifu ya calcium yivu iri hasi cyane, nubunini bwivu ifu ya calcium muri formula yifu yifu igomba kongerwa muburyo bukwiye) Muri icyo gihe, ifitanye isano nubunini nubwiza bwa selile, ibyo bikaba bigaragarira mubipimo byo gufata amazi yibicuruzwa.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.

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

Ibimenyetso bigaragara.Ibi bifitanye isano na selile, ifite imiterere mibi yo gukora film.Muri icyo gihe, umwanda uri muri selile ukora reaction nkeya 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 kandi nibicuruzwa nka carboxymethyl ivanze na selile.

Kugaragara kwa crater na pinholes: Biragaragara ko ibyo bifitanye isano nubushyuhe bwamazi 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 ya calcium ya ivu.Niba ingano yifu ya calcium yivu ari myinshi, ubukana bwifu ya putty iziyongera nyuma yo kumisha.Gusa gukomera kutagira guhinduka bizacika byoroshye, cyane Biroroshye gucika mugihe ukorewe 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?

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 mugihe 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, ubushyuhe buri hejuru gato, kandi ubwiza bwabwo buzagira ingaruka cyane
