Ibibazo bisanzwe byamazi adashobora gushira kurukuta rwimbere

1. Ibibazo bikunze kugaragara mu ifu yuzuye:

1.1 Kuma vuba. Ibi bifitanye isano ahanini no kongeramo calcium yivu nigipimo cyo gufata amazi ya fibre, kandi kijyanye no gukama kwurukuta.

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

1.3 Gukuramo ifu. Ibi bifitanye isano nubunini bwa calcium yivu yongeyeho, kandi bifitanye isano nubunini nubwiza bwa selile yongeyeho. Bigaragarira mu kigero cyo gufata amazi y'ibicuruzwa. Igipimo cyo gufata amazi ni gito kandi igihe cyo gutanga calcium ya ivu ntigihagije.

1.4. Ibi bifitanye isano nubushyuhe bwumye nuburinganire bwurukuta, kandi bifitanye isano nubwubatsi.

1.5 Ingingo ya pin iragaragara. 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 ntigira imbaraga zifatika icyarimwe. Mubyongeyeho, ibi bintu bibaho hamwe nibicuruzwa nka carboxyl matsinda yongewe kuri selile.

1.6 Ibirunga na pinhole biragaragara. Ibi biragaragara ko bifitanye isano nubushyuhe bwamazi ya hydroxypropyl methylcellulose yumuti wamazi. Imeza yamazi ya hydroxyethyl yamazi yumuti ntabwo bigaragara. Byaba byiza gukora imiti irangiye.

1.7 Iyo putty imaze gukama, biroroshye kumeneka no guhinduka umuhondo. Ibi bifitanye isano no kongeramo ubwinshi bwa calcium ya calcium. Niba ingano ya calcium yijimye yongewemo cyane, ubukana bwifu ya putty iziyongera nyuma yo gukama. Gusa gukomera kandi nta guhinduka bizoroha byoroshye, cyane cyane iyo bikorewe imbaraga ziva hanze. Bifitanye isano kandi nibirimo byinshi bya calcium oxyde ya calcium ya calcium, yatangijwe mbere.

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 mugukangura, kandi ibishishwa bikira iyo bihagaze.

3. Kuki putty iremereye mugusiba?

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

4. Kuki putty na minisiteri bikozwe muri selile hamwe nubwiza bumwe bumva bitandukanye mugihe cyizuba nimpeshyi?

Bitewe nubushyuhe bwumuriro wibicuruzwa, ubwiza bwibicuruzwa bizagabanuka 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 mu cyi, cyangwa kongera selile, hanyuma ugahitamo ibicuruzwa bifite ubushyuhe bwinshi bwa gel. Gerageza guhitamo ibicuruzwa bifite ubushyuhe bwa gel hejuru ya dogere 70. Gerageza kudakoresha methyl selulose mu cyi, ubushyuhe bwa gel buri hafi dogere 55, niba ubushyuhe buri hejuru gato, ubukonje bwabwo buzagira ingaruka cyane.
