Kusankhidwa kwa HPMC mamasukidwe akayendedwe popanga putty ufa youma matope?

Dry mortar, yomwe imadziwikanso kuti wall putty, ndi chosakaniza chomwe chimagwiritsidwa ntchito kusalaza ndi kusanja makoma amkati ndi akunja asanapente. Chimodzi mwazinthu zazikulu za matope owuma ndi hydroxypropyl methylcellulose (HPMC), yomwe imakhala ngati thickener ndi binder. Popanga putty powder dry mortar, kusankha koyenera kwa HPMC mamasukidwe akayendedwe ndikofunikira kwambiri kuti zitsimikizire mtundu wa chinthu chomaliza.

HPMC ndi efa ya cellulose, yomwe imakonzedwa pochiza mapadi ndi alkali kenako ndikuchita ndi methyl chloride ndi propylene oxide. HPMC ndi zinthu zosunthika zomwe zimagwiritsidwa ntchito mosiyanasiyana, kuphatikiza pamakampani omanga popanga matope owuma a putty. HPMC imathandizira magwiridwe antchito a putty powder dry mortar popititsa patsogolo kusungidwa kwa madzi, kugwirira ntchito kwake komanso magwiridwe antchito.

Kukhuthala kwa HPMC ndichinthu chofunikira kwambiri chodziwira ntchito ya putty powder dry mortar. Viscosity ndi muyeso wa kukana kwa madzimadzi kuti asayende, nthawi zambiri amawonetsedwa mu centipoise (cP). HPMC imapezeka mu viscosities kuyambira 100 cP mpaka 150,000 cP ndipo, kutengera kagwiritsidwe ntchito, magiredi osiyanasiyana a HPMC amapezeka ndi ma viscosities osiyanasiyana.

Popanga putty powder dry mortar, kusankha kwa HPMC viscosity kuyenera kudalira zinthu zingapo, monga chikhalidwe cha zosakaniza zina, matope osasunthika, komanso chilengedwe. Nthawi zambiri, ma viscosity apamwamba a HPMC amagwiritsidwa ntchito ngati matope okhuthala komanso olemera, pomwe ma viscosity otsika a HPMC amagwiritsidwa ntchito ngati matope ocheperako komanso opepuka.

Ubwino waukulu wogwiritsa ntchito HPMC mu matope owuma a putty ndi kuthekera kwake kowonjezera kusunga madzi. HPMC imayamwa ndikusunga chinyezi, zomwe zimathandiza kuti matope asaume msanga. Izi ndizofunikira makamaka m'madera otentha, owuma, chifukwa matope amatha kuuma mofulumira, zomwe zimapangitsa kuti zisawonongeke komanso kusamamatira bwino. Apamwamba mamasukidwe akayendedwe HPMCs amatha kusunga madzi ochulukirapo, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito pakauma.

Chinthu china chofunikira cha HPMC ndi kuthekera kwake kopititsa patsogolo ntchito. HPMC imagwira ntchito ngati mafuta, kupangitsa kuti matope afalikire mosavuta ndikuchepetsa kuyesetsa komwe kumafunikira kuti pakhale malo osalala. M'munsi mamasukidwe akayendedwe HPMCs zambiri ntchito kuti processability mosavuta, pamene mkulu mamasukidwe akayendedwe HPMCs ntchito zovuta ntchito.

Kuphatikiza pa kusungirako madzi komanso kugwira ntchito kwake, HPMC imathanso kupititsa patsogolo mgwirizano wa putty powder dry mortar. HPMC imapereka mgwirizano wamphamvu pakati pa matope ndi pamwamba omwe akupakidwapo, kuonetsetsa kuti matopewo amakhalabe m'malo mwake ndipo sakusweka kapena kuphulika. Kusankhidwa kwa HPMC mamasukidwe akayendedwe adzakhala ndi chikoka pa mlingo adhesion woperekedwa ndi matope, ndi apamwamba mamasukidwe akayendedwe HPMCs zambiri kupereka bwino adhesion.

Nthawi zambiri, kusankha kwa HPMC mamasukidwe akayendedwe ndizofunikira kwambiri popanga putty ufa wouma matope, ndipo kuyenera kuchitidwa molingana ndi ntchito zenizeni komanso chilengedwe. Posankha kalasi yoyenera ya HPMC, kusunga madzi, kugwira ntchito ndi kugwirizanitsa katundu wa matope akhoza kukonzedwa bwino, kuonetsetsa kuti kutsirizika kwapamwamba kwambiri. Ndi kusankha kolondola kwa HPMC mamasukidwe akayendedwe, ndizotheka kupanga matope owuma a putty omwe amatha kugwiritsidwa ntchito mosavuta komanso moyenera pamapangidwe osiyanasiyana.
