Ku bijyanye na hydroxypropyl methylcellulose mu ikoreshwa ry'ifu ya putty

1. Ibibazo bikunze kugaragara mu ifu ya putty

humuka vuba

Ibi ahanini bifitanye isano n'ingano y'ifu ya kalisiyumu y'ivu yongewemo (ni nini cyane, ingano y'ifu ya kalisiyumu y'ivu ikoreshwa muri formula ya putty ishobora kugabanuka uko bikwiye) hamwe n'umuvuduko wo kubika amazi wa hydroxypropyl methylcellulose (HPMC), kandi bifitanye isano n'ubwumye bw'urukuta.

Gukura no kuzingira

Ibi bifitanye isano n'igipimo cyo kubika amazi, ibyo bikaba byoroshye kubaho iyo ubushyuhe bwa hydroxypropyl methylcellulose (HPMC) buri hasi cyangwa ingano yiyongereyeho ari nto.

Gukuraho ifu y'ifu y'imbere mu rukuta

Ibi bifitanye isano n'ingano y'ifu ya kalisiyumu y'ivu (ingano y'ifu ya kalisiyumu y'ivu muri formula ya putty ni nto cyane cyangwa ubuziranenge bw'ifu ya kalisiyumu y'ivu ni buke cyane, kandi ingano y'ifu ya kalisiyumu y'ivu muri formula ya putty igomba kongerwa uko bikwiye), kandi bifitanye isano n'ingano ya hydroxypropyl methyl. Ingano ya cellulose y'ibanze (HPMC) ifitanye isano n'ubwiza, bugaragarira mu gipimo cyo kubika amazi k'umusaruro. Igipimo cyo kubika amazi ni gito, kandi igihe cyo kubika kalisiyumu y'ivu (calcium oxide mu ifu ya kalisiyumu y'ivu ntigihinduka burundu muri calcium hydroxide) ntabwo gihagije. ,biterwa.

gupfuka

Ibi bifitanye isano n'ubushuhe bwumye n'ubugari bw'urukuta, kandi bifitanye isano n'inyubako.

agace k'agapira

Ibi bifitanye isano na selulose, ifite ubushobozi buke bwo gukora filime. Muri icyo gihe, imyanda iri muri hydroxypropyl methylcellulose (HPMC) ihura gato na calcium y'ivu. Iyo ingaruka ari nyinshi, ifu ya putty izaba iri mu buryo bwa "bean curd residues". Ntishobora gushyirwa ku rukuta, kandi nta mbaraga ifite icyarimwe. Byongeye kandi, ibintu nka hydroxypropyl methylcellulose (HPMC) bivanze na carboxymethyl group nabyo bigaragara muri iki gihe.

Ibirunga n'imyobo y'ingobyi biragaragara

Ibi birumvikana ko bifitanye isano n'umuvuduko w'amazi wa hydroxypropyl methylcellulose (HPMC) mu gisubizo cy'amazi. Umuvuduko w'amazi wa hydroxyethyl mu gisubizo cy'amazi ntugaragara. Byaba byiza gukora ubuvuzi bwa nyuma.

Iyo putty yumye, biroroshye kuyimena no kuyihindura umuhondo

Ibi bifitanye isano no kongeramo ifu nyinshi y'umukungugu w'ivu-kalisiyumu. Iyo ifu y'umukungugu w'ivu-kalisiyumu yongewemo cyane, ubukana bw'ifu y'umukungugu bwiyongera nyuma yo kuma. Iyo ifu y'umukungugu idafite ubworoherane, izacika byoroshye, cyane cyane iyo ikoreshejwe imbaraga zo hanze. Bifitanye isano kandi n'ingano nini ya oksidi ya kalisiyumu mu ifu ya kalisiyumu y'ivu.

2. Kuki ifu ya putty irushaho kuba nto nyuma yo kongeramo amazi?

Hydroxypropyl methylcellulose (HPMC) ikoreshwa nk'ikintu gikomeza ubushyuhe no kubika amazi mu binure. Bitewe n'uko thixotropy ya hydroxypropyl methylcellulose (HPMC) ikora, hydroxypropyl methylcellulose mu ifu ya putty. Kongeramo HPMC byanateye thixotropy nyuma yo kongeramo amazi muri putty. Iyi thixotropy iterwa no kwangirika kw'imiterere y'ibice biri mu ifu ya putty. Iyi miterere ivuka iyo iruhutse kandi igasenyuka iyo hari stress. Ni ukuvuga ko viscosity igabanuka iyo ivanzwe, kandi viscosity ikagaruka iyo ihagaze.

3. Ni iyihe mpamvu ituma puti iba iremereye mu gihe cyo kuyisya?

Muri iki gihe, ubukana bwa hydroxypropyl methylcellulose (HPMC) ikoreshwa muri rusange buba buri hejuru cyane, kandi bamwe mu bakora putty bakoresha yuan 200.000. Putty ikorwa muri ubu buryo ifite ubukana bwinshi, bityo iramanuka iyo ikoreshejwe mu gukata. Ingano ya putty isabwa ku nkuta z'imbere ni 3-5 kg, naho ubukana ni 80.000-100.000.

4. Kuki wumva ko ubukana bwa hydroxypropyl methylcellulose (HPMC) bufite ubukana bumwe butandukanye mu gihe cy'itumba no mu mpeshyi?

Bitewe n'ubushyuhe bw'ibicuruzwa, ubushyuhe bwa putty na mortier bugenda bugabanuka buhoro buhoro uko ubushyuhe bwiyongera. Iyo ubushyuhe burenze ubushyuhe bwa gel bw'ibicuruzwa, ibicuruzwa bizava mu mazi bigatakaza ubushyuhe bwabyo. Ubushyuhe bw'icyumba muri rusange burenze dogere 30, bitandukanye cyane n'ubushyuhe bwo mu gihe cy'itumba, bityo ubushyuhe buba buri hasi. Ni byiza guhitamo ibicuruzwa bifite ubushyuhe bwinshi iyo ukoresha ibicuruzwa mu mpeshyi, cyangwa kongera ingano ya hydroxypropyl methylcellulose (HPMC), no guhitamo ibicuruzwa bifite ubushyuhe bwinshi bwa gel.
