Doorka hydroxypropyl methylcellulose ee Putty

Doorka hydroxypropyl methylcellulose ee Putty

Laga bilaabo dhumucda, haynta biyaha iyo dhismaha saddex shaqo.

Dhumuc: Cellulose waa la dhumuc karaa si loo hakiyo, loo ilaaliyo xalka midaysan oo joogto ah, loona diido inuu dhaco. Haynta biyaha: Ka dhig budada putty-ga mid si tartiib ah u qallajisa, oo ka caawisa falcelinta calcium-ka dambaska iyadoo la adeegsanayo biyaha. Dhismaha: Cellulose waxay leedahay saameyn saliidayn ah, taasoo ka dhigi karta budada putty-ga inay si fiican u shaqeyso. Hydroxypropyl methylcellulose kama qayb qaadato falgal kiimiko ah waxayna ka ciyaartaa door kaabayaal ah oo keliya. Budada putty-ga waxaa lagu daraa biyo si loogu dubo derbiga, kaas oo ah falgal kiimiko ah, sababtoo ah waxaa jira sameynta walax cusub oo calcium carbonate ah. Qaybaha ugu muhiimsan ee budada calcium-ka dambaska waa: isku darka calcium hydroxide Ca(OH)2, calcium oxide CaO iyo xaddi yar oo calcium carbonate CaCO3 ah. Calcium-ka dambaska wuxuu sameeyaa calcium carbonate isagoo ku jira ficilka CO2 ee biyaha iyo hawada, halka hydroxypropyl methyl Cellulose uu hayo biyaha oo uu caawiyo falcelinta wanaagsan ee calcium-ka dambaska, kaas oo laftiisu aan ka qayb qaadan wax falgal ah.

Marka hore waxaan falanqeyneynaa sababaha hoos u dhaca budada putty ee ka yimaada walxaha ceeriin ee putty: budada calcium ee dambaska, hydroxypropyl methylcellulose, budada calcium ee culus, budada calcium ee dambaska biyaha

1. Wax soo saarka dhabta ah, si loo dedejiyo kala-baxa, heerkulka kalsiyumka waxaa badanaa la kordhiyaa ilaa 1000-1100 °C. Sababtoo ah cabbirka weyn ee walxaha ceeriin ee nuuradda ama qaybinta heerkulka aan sinnayn ee foornada inta lagu jiro kalsiyumka, nuuraddu waxay inta badan ka kooban tahay liin aan la shidin iyo liin aan la shidin. Kaalshiyamka kaarboonat ee ku jira liinta dabka ah gebi ahaanba ma burburo, mana laha awood isku xiran inta la isticmaalayo, taas oo aan siin karin xoog isku xiran oo ku filan putty-ga, taasoo keenta in budo laga saaro taasoo ay keento adkaanta iyo xoogga aan ku filnayn ee putty-ga.

2. Inta badan ee kaalshiyamka hydroxide ku jiro budada kaalshiyamka dambaska, ayaa ka sii adkaanta putty-ga ee la soo saaro. Taas beddelkeeda, hoos u dhaca ku jira kaalshiyamka hydroxide ee ku jira budada kaalshiyamka dambaska, ayaa ka sii daraya adkaanta putty-ga ee goobta wax soo saarka, taasoo keenta dhibaatada ka saarista budada iyo ka saarista budada.

3. Budada kaalshiyamka dambaska waxaa lagu qasaa tiro badan oo ah budada kaalshiyamka culus, taasoo keenta in maadada kaalshiyamka dambaska ay aad u hooseyso si ay u siiso adkeysi iyo xoog ku filan putty-ga, taasoo keenta in putty-gu uu daadiyo budada. Shaqada ugu weyn ee budada putty waa inay ilaaliso biyaha, bixiso biyo ku filan si loo adkeeyo budada kaalshiyamka dambaska, iyo hubinta saameyn ku filan oo adkeysi leh. Haddii ay jirto dhibaato ku saabsan tayada hydroxypropyl methylcellulose ama maaddada waxtarka leh ay yar tahay, qoyaan ku filan lama bixin karo, taasoo sababi doonta in adkeysigu uusan ku filnayn oo sababi doonta in putty-gu uu daadiyo budada.

Waxaa laga heli karaa kor ku xusan in tayada hydroxypropyl methylcellulose ay aad u liidato oo aysan gaari karin saameyn gaar ah, budada putty-na ay hoos u dhici doonto. Sababta ugu weyn waa calcium culus oo cawlan.
