Ibibazo bisanzwe nibisubizo biterwa na selile mugukoresha ifu ya putty

1. Ibibazo bisanzwe mubifu

Kuma vuba. Ibi biterwa ahanini nuko ingano yifu ya calcium yivu yongewemo (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.

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 yinkuta yimbere imbere. Ibi bifitanye 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 ni bike cyane, kandi ingano yifu ya calcium yivu mumata yifu ya putty igomba kwiyongera neza), kandi bifitanye isano no kongeramo selile. Hariho isano hagati yubwinshi nubwiza, bigaragarira mubipimo byo gufata amazi kubicuruzwa. Igipimo cyo gufata amazi ni gito, kandi ifu ya calcium ya ivu (oxyde ya calcium mu ifu ya calcium yivu ntabwo ihindurwa rwose na hydroxide ya calcium ya hydration) igihe ntigihagije, ibyo bikaba biterwa.

bubbly. 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 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 yuko amazi yongewemo 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.
