Mphamvu ya Cellulose Ether pa Zomatira za Tile

Zomatira zomatira za simenti pakali pano ndizomwe zimagwiritsidwa ntchito kwambiri pamatope osakanikirana owuma, omwe amapangidwa ndi simenti monga chinthu chachikulu cha simenti ndikuphatikizidwa ndi magulu ophatikizika, osungira madzi, othandizira mphamvu zoyambira, ufa wa latex ndi zina zowonjezera organic kapena organic. kusakaniza.Nthawi zambiri, zimangofunika kusakanikirana ndi madzi zikagwiritsidwa ntchito.Poyerekeza ndi matope wamba wa simenti, imatha kusintha kwambiri mphamvu yomangirira pakati pa zinthu zomwe zikuyang'anizana ndi gawo lapansi, ndipo imakhala ndi kukana kwabwino komanso kukana madzi komanso kukana kutentha.Ndipo ubwino wa amaundana-thaw mkombero kukana, makamaka ntchito muiike nyumba mkati ndi kunja khoma matailosi, matailosi pansi ndi zipangizo zina zokongoletsera, chimagwiritsidwa ntchito mkati ndi kunja makoma, pansi, mabafa, khitchini ndi zina zomangamanga malo zokongoletsera, panopa ndi Zomwe zimagwiritsidwa ntchito kwambiri ndi zida za ceramic matailosi.

Kawirikawiri tikamaweruza ntchito ya zomatira matailosi, sitimangoganizira za ntchito yake komanso mphamvu zotsutsana ndi kutsetsereka, komanso kumvetsera mphamvu zake zamakina ndi nthawi yotsegula.Cellulose ether mu zomatira matailosi osati zimakhudza rheological katundu za porcelain zomatira, monga ntchito yosalala, kumamatira mpeni, etc., komanso ali ndi chikoka champhamvu pa makina zimatha zomatira matailosi.

1. Maola otsegulira

Pamene ufa mphira ndi mapadi etero kukhalapo mu chonyowa matope, zitsanzo zina deta zimasonyeza kuti ufa mphira ali wamphamvu kinetic mphamvu angagwirizanitse simenti hydration mankhwala, ndi mapadi etero alipo kwambiri mu interstitial madzimadzi, zomwe zimakhudza kwambiri Mortar mamasukidwe akayendedwe ndi kuika nthawi.Kuthamanga kwapamtunda kwa cellulose ether ndikokulirapo kuposa ufa wa rabara, ndipo kuchuluka kwa cellulose ether komwe kumapangidwira pamawonekedwe amatope kudzakhala kopindulitsa pakupanga zomangira za haidrojeni pakati pa maziko oyambira ndi mapadi a cellulose.

Mumtondo wonyowa, madzi mumtondo amasanduka nthunzi, ndipo cellulose ether imapindula pamwamba, ndipo filimu idzapangidwa pamwamba pa matope mkati mwa mphindi 5, zomwe zidzachepetsa kuchepa kwa evaporation, monga madzi ochulukirapo. kuchotsedwa matope wandiweyani Mbali ya izo amasamukira ku woonda matope wosanjikiza, ndi filimu anapanga pachiyambi ndi pang'ono kusungunuka, ndi kusamuka kwa madzi adzabweretsa kwambiri mapadi etere kulemeretsa pa matope pamwamba.

Mapangidwe a filimu ya cellulose ether pamwamba pa matope amakhudza kwambiri ntchito ya matope:

1. Filimu yopangidwa ndi yowonda kwambiri ndipo idzasungunuka kawiri, osakhoza kuchepetsa kutuluka kwa madzi ndikuchepetsa mphamvu.

2. Filimu yopangidwa ndi yokhuthala kwambiri.Kuchuluka kwa cellulose ether mu matope amadzimadzi am'madzi ndipamwamba komanso kukhuthala kwake ndikwambiri.Sikophweka kuthyola filimu pamwamba pamene matailosi amaikidwa.

Zitha kuwoneka kuti mawonekedwe opanga mafilimu a cellulose ether amakhudza kwambiri nthawi yotseguka.Mtundu wa cellulose ether (HPMC, HEMC, MC, etc.) ndi digiri ya etherification (digiri yolowa m'malo) imakhudza mwachindunji mapangidwe a filimu a cellulose ether, ndi kuuma ndi kulimba kwa filimuyo.
