Uruhare rwa hydroxypropyl methylcellulose muri putty

Uruhare rwa hydroxypropyl methylcellulose muri putty

Kuva ku gukomera, kubika amazi no kubaka imirimo itatu.

Gukomera: Selilulose ishobora gukongerwa kugira ngo ihagarare, ikomeze kugira umuti umwe kandi uhamye, kandi irinde kugwa. Amazi agumana: Ifu ya putty yumuke buhoro buhoro, kandi ifashe imikorere ya calcium y'ivu munsi y'amazi. Imiterere: Selilulose ifite ubushobozi bwo gusiga amavuta, bishobora gutuma ifu ya putty ikora neza. Hydroxypropyl methylcellulose ntabwo igira uruhare mu mikorere iyo ari yo yose ya shimi kandi igira uruhare rw'inyongera gusa. Ifu ya putty yongerwaho n'amazi kugira ngo ifatanye n'urukuta, ari na yo mikorere ya shimi, kuko haba hari ikintu gishya cya calcium carbonate. Ibice by'ingenzi bya calcium calcium ivu ni: uruvange rwa calcium hydroxide Ca(OH)2, calcium oxide CaO n'ingano nto ya calcium carbonate CaCO3. Ivu rya calcium carbonate rikora calcium carbonate munsi y'imikorere ya CO2 mu mazi no mu mwuka, mu gihe hydroxypropyl methyl Cellulose igumana amazi gusa kandi igafasha imikorere myiza ya calcium ivu, nayo ubwayo itagira uruhare mu mikorere iyo ari yo yose.

Tubanza gusesengura impamvu zituma ifu ya putty igabanuka mu bikoresho fatizo bya putty: ifu ya kalisiyumu y'ivu, hydroxypropyl methylcellulose, ifu ya kalisiyumu iremereye, ifu ya kalisiyumu y'ivu ry'amazi

1. Mu musaruro nyawo, kugira ngo ivunguke, ubushyuhe bwa calcination bukunze kwiyongera bukagera kuri 1000-1100 °C. Bitewe n'ingano nini y'ibikoresho by'ibanze bya lime cyangwa ubushyuhe budakwirakwira mu itanura mu gihe cyo gukaraba, lime ikunze kuba irimo lime idashyushye cyane n'indimu ishyushye cyane. Karubone karubone iri mu lyumu idashyushye ntabwo ibora burundu, kandi ibura imbaraga zifatanye mu gihe cyo kuyikoresha, ibyo bikaba bidashobora gutanga imbaraga zihagije ku plati, bigatuma ifu ikurwaho bitewe n'ubukana budahagije n'imbaraga za puti.

2. Uko kalisiyumu hidroksidi nyinshi mu ifu ya kalisiyumu y'ivu ingana, niko ubukana bwa putty burushaho kwiyongera. Ahubwo, uko kalisiyumu hidroksidi iba nke mu ifu ya kalisiyumu y'ivu ingana, ni ko ubukana bwa putty burushaho kwiyongera aho ikorwa, bigatera ikibazo cyo gukuraho ifu no gukuraho ifu.

3. Ifu ya kalisiyumu y'ivu ivangwa n'ifu nyinshi ya kalisiyumu ikomeye, bigatuma ingano y'ifu ya kalisiyumu y'ivu iba nke cyane ku buryo itabasha gukomera no gukomera bihagije kuri putty, bigatuma putty igwa. Akamaro k'ifu ya putty ni ukubika amazi, gutanga amazi ahagije yo gukomeza ifu ya kalisiyumu y'ivu, no kwemeza ko ikomera rihagije. Iyo hari ikibazo ku bwiza bwa hydroxypropyl methylcellulose cyangwa ingano yayo ikaba nke, ubushuhe buhagije ntibushobora gutangwa, bigatuma gukomera kudahagije bigatuma putty igwa.

Bigaragara ko ubuziranenge bwa hydroxypropyl methylcellulose ari bubi cyane kandi budashobora kugera ku ngaruka runaka, kandi ifu ya putty izagwa. Impamvu nyamukuru ni calcium nyinshi ya gray beggar.
