Zotsatira za Cellulose Ether pa Adhesive Force of Mortar

Ma cellulose ethers ndi zowonjezera zowonjezera pazinthu zomangira, kuphatikizapo matope, ndipo akhala akugwiritsidwa ntchito pamakampani omanga amakono kwa zaka zambiri. Imapezeka m'mitundu yambiri ndi magiredi, ndipo kusankha kwa cellulose ether kumatengera zomwe akufuna komanso zomwe zidapangidwa pomaliza.

Kawirikawiri, ether ya cellulose imapangitsa kuti matope azigwira ntchito bwino, amapangitsa kuti madzi azikhala ndi madzi komanso amamatira ku gawo lapansi. M'nkhaniyi, tidzakambirana za momwe ma cellulose ethers amakhudzira matope, chinthu chofunika kwambiri cha matope.

Kumatira ndiko kuthekera kwa chinthu chimodzi kumamatira ku china monga gawo lapansi pomwe matope amayikidwa. Kumatira kwamatope ndikofunikira pakukhalitsa komanso kugwira ntchito kwanthawi yayitali kwa zomanga. Zomwe zimakhudza kumamatira kwa matope ndi monga gawo lapansi, katundu wamatope, ndi chilengedwe.

Selulosi ether bwino adhesion wa matope ndi bwino rheological ndi makina zimatha matope. Choyamba, ma cellulose ethers amawongolera rheology ya matope powonjezera kugwirira ntchito kwawo ndikuchepetsa kulekanitsa. Kugwira ntchito kumatanthawuza kumasuka komwe matope amasakanikirana, kuikidwa ndi kutsirizidwa, pamene kulekanitsa kumatanthauza kulekanitsa zigawo zamatope panthawi yosakaniza kapena yogwira. Rheology ya matope imapangidwa bwino, kulola kuti iziyenda ndikudzaza mipata pakati pa gawo lapansi ndi matope kuti amamatire bwino.

Chachiwiri, ma cellulose ethers amawongolera magwiridwe antchito a matope, monga kulimba kwake komanso kuphatikizika kwake, zomwe ndizofunikira kwambiri kuti matopewo amamatire ku gawo lapansi. Ma cellulose ether amawongolera magwiridwe antchito a matope ndikuwongolera ma hydration ake, njira yomwe simenti mumatope imakhudzidwa ndi madzi kuti ikhale yolimba.

Kukhalapo kwa cellulose ether mu matope kumachepetsa kuthamanga kwa madzi mumatope, zomwe zimapangitsa kuti madzi azikhala ndi nthawi yayitali. Njira yotalikirapo ya hydration imapanga mgwirizano wokulirapo, wamphamvu pakati pa matope ndi gawo lapansi kuti limamatire bwino.

Ma cellulose ether omwe amagwiritsidwa ntchito mumatope amabwera m'makalasi ndi mitundu yosiyanasiyana, kuphatikiza methylcellulose, hydroxyethylcellulose, ndi hydroxypropylcellulose. Methylcellulose ndi mtundu wofala kwambiri ndipo ndi woyenera kugwiritsa ntchito zosiyanasiyana chifukwa cha kuchuluka kwake kosungira madzi, kutheka, komanso kumamatira bwino. Komano, cellulose ya hydroxyethyl ndi hydrophilic ndipo imatha kuyamwa ndikusunga madzi, potero imakulitsa kugwira ntchito kwa matope ndi kumamatira kwake ku gawo lapansi. Ma cellulose a Hydroxypropyl ndioyenera kukulitsa komanso kukulitsa mawonekedwe a matope a matope, motero amawongolera kumamatira.

Mwachidule, cellulose ether ndi chowonjezera chofunikira pantchito yomanga ndipo imagwira ntchito yofunika kwambiri pakuwongolera kumamatira kwamatope. Kukhalapo kwa mapadi etero mu matope timapitiriza ake rheological ndi makina katundu, chifukwa mu workability bwino, hydration ndi adhesion kwa gawo lapansi. Kusankhidwa kwa cellulose ether kumadalira ntchito yomwe ikufunidwa ndi zomwe zimafunidwa pazomaliza. Mukamagwiritsa ntchito cellulose ether mumatope, malangizo a wopanga ayenera kutsatiridwa kuti akwaniritse zotsatira zabwino ndikuwonetsetsa kukhazikika komanso kugwira ntchito kwa nthawi yayitali kwa nyumbayo.
