Uruhare rwa hydroxypropyl methylcellulose muri putty

Uruhare rwa hydroxypropyl methylcellulose muri putty

Kuva kubyimbye, kubika amazi no kubaka imirimo itatu.

Kubyimba: Cellulose irashobora kubyimba kugirango ihagarike, igumane igisubizo kimwe kandi gihamye, kandi irinde kugabanuka. Kubika amazi: Kora ifu ya putty yumye buhoro, kandi ufashe reaction ya calcium yivu munsi yamazi. Ubwubatsi: Cellulose igira amavuta yo kwisiga, ishobora gutuma ifu ya putty igira imikorere myiza. Hydroxypropyl methylcellulose ntabwo yitabira imiti iyo ari yo yose kandi igira uruhare gusa. Ifu yuzuye yongewemo namazi kugirango batere urukuta, aribwo buryo bwa chimique, kuko hariho kwibumbira mubintu bishya bya calcium karubone. Ibice byingenzi bigize ifu ya calcium yivu ni: imvange ya calcium hydroxide Ca (OH) 2, calcium oxyde CaO hamwe na calcium ya karubone ya CaCO3. Kalisiyumu yivu ikora calcium karubone ikorwa na CO2 mumazi no mwuka, mugihe hydroxypropyl methyl Cellulose igumana amazi gusa ikanafasha kwitwara neza kwa calcium yivu, nayo ubwayo ntigire uruhare mubitekerezo.

Twabanje gusesengura impamvu zitera ifu yigitonyanga cyibikoresho biva mubikoresho fatizo: ifu ya calcium yivu, hydroxypropyl methylcellulose, ifu ya calcium iremereye, ifu ya calcium yamazi

1. Mu musaruro nyirizina, kugirango wihutishe kubora, ubushyuhe bwo kubara akenshi bwiyongera kuri 1000-1100 ° C. Bitewe nubunini bunini bwibikoresho fatizo bya hekeste cyangwa ikwirakwizwa ryubushyuhe butaringaniye mu itanura mugihe cyo kubara, lime akenshi iba irimo lime idacanwa kandi ikarenza urugero. Kalisiyumu ya karubone mu ndimu yumuriro ntishobora kubora rwose, kandi ikabura imbaraga zifatika mugihe cyo kuyikoresha, idashobora gutanga imbaraga zihagije kuri putty, bikavamo kuvanaho ifu biterwa nuburemere budahagije nimbaraga za putty.

2. Iyo hejuru ya calcium hydroxide ya calcium mu ifu ya calcium yivu, niko gukomera kwa putty byakozwe. Ibinyuranye na byo, uko hasi ya hydroxide ya calcium iri mu ifu ya calcium ya ivu, niko ubukana bwa putty ahakorerwa, bikavamo ikibazo cyo kuvanaho ifu no kuvanaho ifu.

3. Igikorwa nyamukuru cyifu ya putty nukugumana amazi, gutanga amazi ahagije yo gukomera kwifu ya calcium yivu, kandi bikagira ingaruka zikomeye zo gukomera. Niba hari ikibazo cyubwiza bwa hydroxypropyl methylcellulose cyangwa ibirimo neza ni bike, ubushuhe buhagije ntibushobora gutangwa, ibyo bigatuma gukomera bidahagije kandi bigatera gushira ifu.

Birashobora kuboneka kuva hejuru ko ubwiza bwa hydroxypropyl methylcellulose ari bubi cyane kandi ntibushobora kugera ku ngaruka runaka, kandi ifu ya putty izagwa. Impamvu nyamukuru ni imvi zisabiriza calcium iremereye.
