Choyamba. Choyamba mumvetsetseKubwezeretsedwa Polimer Polyder.
Kumwatsetsa ufa wa polima ndi ma policers opangidwa kuchokera ku polymer emulsions kudzera pakuwuma kolondola (ndikusankha kowonjezera koyenera). Ufa wowuma ufa umasandulika madzi, ndipo amatha kuchepetsedwa panthawi yophatikiza ndi matope owumitsa thupi Emulsion polymeon, omwe amatha kukonza matope a simenti. Kugonana. Emulsion Wouma ufa wosinthika umatchedwa matope a ufa (amatchedwanso matope osakanikirana osakanizidwa, matope owuma). Popeza ufa wouma suyenera kuganizira za emulsion ndikukhazikika ngati emulsions emulsions, kuphatikiza pang'ono kumatha kupanga matope omwe akufuna, ndipo ali ndi magwiridwe antchito osavuta, antifutisi ndipo ayi Kukula kwa nkhuni, ndi mwayi womwe ukhoza kupanga chinthu chimodzi chophatikizira ndi simenti yosakaniza monga simenti ndi mchenga, ndipo zitha kugwiritsidwa ntchito powonjezera madzi.
Mukamagwiritsa ntchito, sakanizani ndi mchenga, simenti, emulsion owuma ufa pasadakhale, ndikungofunika kuwonjezera madzi opangidwa ndi tsamba kuti apange matope owuma. Pakati pa kupanga kwa ufa wouma ufa ndikuti polymer tinthu tofana ndi ufa wa matex muoneke tinthu tating'onoting'ono kapena tinthu tating'onoting'ono tinthu tating'onoting'ono kapena tinthu tating'onoting'ono tofanana ndi tinthu tating'onoting'ono tofanana ndi tinthu tating'onoting'ono. Colloid yoteteza monga mowa wa polyvinyl iyenera kuwonjezeredwa ku emulsion, kuti ufa wa latex ukhoza kutumizidwanso mu emulsion akamalumikizana ndi madzi. Ndi akapolo abwino omwe ufa wa latx ungathe kuchita bwino kwambiri. . Ufa wofatsa polima nthawi zambiri umakhala ufa. Zosakaniza zake ndi monga:
Polymer Resin: ili mkati mwa gawo la mphira wa mphira, ndipo ndi gawo lalikulu la ufa wobwezeretsera.
Zowonjezera (zamkati): Pamodzi ndi utomoni, imagwira ntchito yosintha maten. Zowonjezera (zakunja): Zipangizo zowonjezera zimawonjezeredwa kuti ziwonjezere magwiridwe antchito omwazika ndi ufa.
Colloid colloid: wosanjikiza wa zinthu zokutira utakulungidwa pamwamba pa tinthu tating'onoting'ono tofanana ndi tinthu tating'onoting'ono tofana, zotetezera za ufa wambiri ndi mowa wa polyvinyl.
Anti-Cating Active: Migodi Yabwino Kwambiri, makamaka kuteteza ufa wa mphira kuti usayendetse ufa wa mphira (wotayika m'matumba.)
Kodi mungadziwe bwanji mtundu wa ufa wobwezeretsedwa?
Njira 1, Ndondomeko Ya Ash
Tengani kuchuluka kwa ufa wokwezedwa, ikani chidebe chachitsulo mutalemera, kumatenthe mpaka madigiri 500, mutachiritsa kutentha kwambiri kwa madigiri 500, ndikuziziritsa kutentha kwa chipinda, ndikulemeranso. Kulemera komanso bwino.
Njira ziwiri, zotsutsana
Tengani kuchuluka kwa ufa wokwezedwa ndikusungunuka nthawi 5 madzi, sakani bwino ndikuloleza kuti ayime kwa mphindi 5 musanawone. M'malo mwake, zokonda zochepa zomwe zimakhala pansi, zabwino za mtundu wobwezeretsedwa polima. Njirayi ndiyosavuta komanso yosavuta.
Njira zitatu, njira yopanga filimu
Tengani mtundu wina wa ufa wokwezeka wa latex wosinthidwa, madziwo m'ma 2 madzi, zisunthire kwa mphindi ziwiri, kuyika kachiwiri, ndikuyikagalasi pamalo opumira . Chotsani mukamauma. Onani kanema wochotsa polymer. Kuwonekera kwakukulu ndi zabwino. Kenako kokerani pang'ono, ndikukula bwino komanso zabwino. Kanemayo anabereka mu mizere, kumizidwa m'madzi, ndipo patatha tsiku limodzi, kanemayo sanali kusungunuka m'madzi. Njirayi ndiyofunika kwambiri
