1 Ibibazo bikunze kugaragara mu ifu ya putty:
(1) Kuma vuba.
Ibi biterwa ahanini 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.
(2) Kuramo no kuzunguruka.
Ibi bifitanye isano nigipimo cyo gufata amazi, byoroshye kugaragara mugihe ubwiza bwa selile ari buke cyangwa umubare winyongera ukaba muto.
(3) De-powder yinkuta yimbere imbere ifu yifu.
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 yivu (okiside ya calcium iri mu ifu ya calcium y ivu ntabwo ihindurwa rwose na calcium hydroxide ya hydration) igihe ntigihagije, ibyo bikaba biterwa.
(4) Ibibyimba.
Ibi bifitanye isano nubushyuhe bwumye nuburinganire bwurukuta, kandi bifitanye isano nubwubatsi.
(5) 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 ntigira imbaraga zifatika icyarimwe.Mubyongeyeho, ibi bintu bibaho hamwe nibicuruzwa nka carboxyl matsinda yongewe kuri selile.
(6) Ibyobo byibirunga na pinhole 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.
(7) 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 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 Ni ukubera iki putty iremereye muburyo bwo gusiba?
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 gushira kurukuta rwimbere ni kg 3-5, naho viscosity ni 80.000-100.000.
4 Ni ukubera iki ibishishwa na minisiteri bikozwe muri selile bifite ubukonje bumwe bumva bitandukanye mu gihe cy'itumba n'izuba?
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 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 hafi dogere 55, niba ubushyuhe buri hejuru gato, ububobere bwabwo buzagira ingaruka cyane.
