Kubaluleke kangakanani ubusu be-cellulose ether kuya odabula udaka

Yimiphi imiphumela ehlukile ye-cellulose ehlukile ku-plaster of paris

Kokubili i-carboxymethyl cellulose ne-methyl celtule paris. Inethonya lokubuyisa futhi linciphise amandla odaka lweParis. I-Methyl celtuleose iyinhlangano yokuhlanganiswa ekahle yezinto zokwakha ze-gypsum cementios ezihlanganisa ukugcinwa kwamanzi, ukuqina, ukuqiniswa, nokubona, ngaphandle kokuthi ezinye izinhlobo ziba nomphumela wokubuyisa lapho kukhulu. ephakeme kune-carboxymethyl cellulose. Ngalesi sizathu, izinto eziningi ze-gypsum composite gelling gelling zamukela indlela yokuhlanganisacarboxymethyl cellulosena-methyl cellulose, okungagcini nje kuphela ngezimpawu zazo ezifanele (njengomphumela wokugcina kabusha we-carboxymethyl cellulose, umphumela wokuqinisa i-methyl celtule Ngale ndlela, ukusebenza kokugcinwa kwamanzi kwama-gypsum cementional impahla ye-gypsum kanye nokusebenza okuphelele kwe-gypsum cementional impahla ehleliwe, ngenkathi ukukhuphuka kwezindleko kugcinwa endaweni ephansi kakhulu.

Kubaluleke kangakanani ukubonakala kwe-methyl cellulose ether ngodaka lwe-gypsum?

I-Viscosity iyipharamitha ebalulekile ye-methyl cellulose ukusebenza.

Ngokuvamile, okuphezulu kwe-viscosity, kungcono umphumela wokugcina amanzi we-gypsum udaka. Kodwa-ke, ukukhuphuka kwesisindo esiphakeme, isisindo samangqamuzana se-methyl cellulose ether, kanye nokuncipha okuhambisanayo kwe-solubelity yakhe kuzoba nomthelela ongemuhle emandleni nasekusebenzeni kokwakha kodaka. Lapho kuphakama i-viscosity, kusobala kakhulu umphumela wokuqina kudaka, kepha akayona ngokuqondile. Lapho esekhuphuka khona ukubonwa, okuzoba khona ngodaka olumanzi. Ngesikhathi sokwakha, kubonakaliswa njengokunamathela ku-scraper kanye nokunamathela okuphezulu kuya engxenyeni engezansi. Kepha akusizi ukwandisa amandla wesakhiwo sodaka olumanzi uqobo. Ngaphezu kwalokho, ngesikhathi sokwakha, ukusebenza kwe-anti-sag ngodaka olumanzi akubonakali. Ngokuphambene nalokho, ukubonakala okuphakathi nendawo okuphansi kepha okulungiselelwe i-methyl cellulose kanye nokusebenza okuhle kakhulu ekuthuthukiseni amandla wesakhiwo sodaka lwamanzi.

Kubaluleke kangakanani ukubukeka kwe-cellulose ether kuya odabula udaka?

I-Fechness nayo iyinkomba yokusebenza ebalulekile ye-methyl celtulose ether. I-MC esetshenziselwa udaka lwe-powder eyomile iyadingeka ukuba ibe yimpuphu ngokuqukethwe kwamanzi okuphansi, futhi ubuciko futhi budinga ama-20% kuye kwangama-60% kasayizi wezinhlayiyana kube ngaphansi kwama-63m. Ubuhle buthinta i-solubility ye-methyl cellulose ether. I-Coarse MC imvamisa i-granular, okulula ukuyihlakaza futhi ichithe emanzini ngaphandle kwe-agglomeration, kepha izinga lokuchithwa lihamba kancane, ngakho-ke alilungele ukusetshenziswa ngodaka lwempuphu owomile. Eminye imikhiqizo yasekhaya i-Flocculent, hhayi okulula ukuhlakazeka futhi ichithe emanzini, futhi kulula kakhulu ukuba ne-agglomerate. Ku-powder eyomile, i-MC ihlakazeka phakathi kwezinto zokubhala ezifana ne-aggregate, i-filler enhle kanye nosimende, futhi i-powder enhle kuphela engavikela ama-methyl cellulose agglomeration lapho uxubana namanzi. Lapho i-MC ingezwa ngamanzi ukuncibilikisa ama-agglomerates, kunzima kakhulu ukusakazeka futhi uncibilike. -MaqhafuqhafuMCAkugcini nje ngokuchitheka, kepha futhi kunciphisa amandla endawo odaka. Lapho kufakwa i-powder enjalo esomile endaweni enkulu, ijubane lokuphulukisa kodaka lwendawo luzoncishiswa kakhulu, futhi imifantu izovela ngenxa yezikhathi ezihlukile zokwelapha. Owesifazane ofafazwe onokwakhiwa kwemishini, imfuneko yobunzima iphakeme ngenxa yesikhathi esifushane sokuxuba.

Ubumsulwa be-MC bubuye bube nomthelela othile ekugcinweni kwalo kwamanzi. Ngokuvamile, ngokujwayelekile, i-methyl cellulose izithatheketha ngokubonakala okufanayo kodwa kube nobunzima obuhlukile, ngaphansi kwenani elifanayo lezengezo.
