Redispersible ufa VAE
Zogulitsa za ufa wa polima zofalitsanso ndizatsopano kwambiri pantchito yomanga ndi mafakitale, zomwe zimapereka mayankho osiyanasiyana chifukwa cha zomwe ali nazo komanso kuthekera kwawo. Mafutawa amasungunuka m'madzi ndipo amatha kugawidwa m'magulu osiyanasiyana malinga ndi momwe amapangira mankhwala, kuphatikizapo ethylene/vinyl acetate copolymers, vinyl acetate/ethylene terephthalate copolymers, ndi acrylic acid copolymers. Mtundu uliwonse wa copolymer umapereka mawonekedwe apadera omwe amagwiritsidwa ntchito mosiyanasiyana m'mafakitale osiyanasiyana, kuyambira zomatira mpaka zokutira, potero amakulitsa kuthekera kogwiritsa ntchito pazinthu zosiyanasiyana zomangira. Kusinthasintha kumeneku ndikofunikira pakukwaniritsa zomwe zikuchulukirachulukira zazinthu zapamwamba zomwe zimathandizira kuti magwiridwe antchito azigwira bwino ntchito komanso kulimba kwazinthu zatsiku ndi tsiku.
Njira yopangira ma polima opangidwanso ndi dispersible powders imaphatikizapo njira zowumitsa zopopera, zomwe zimapangitsa kuti pakhale tinthu tating'onoting'ono ta ufa tomwe titha kuwongolera ndi kukonza. Chofunika kwambiri, ma ufawa amatetezedwa ndi mowa wa polyvinyl panthawi yopanga, kuonetsetsa kuti amasunga umphumphu wawo mpaka atakonzeka kubalalitsidwanso. Ufa womwazikanso uwu ukakumana ndi madzi, ukuwonetsa kuthekera kwapadera kobwereranso kumadzi, zomwe zimapangitsa kuti zigwiritsidwe ntchito mosiyanasiyana. Khalidweli ndi lofunika makamaka m'malo omwe kuchita bwino kwa nthawi ndikofunikira, chifukwa kumalola makontrakitala ndi akatswiri amakampani kuti azigwira ntchito mosasunthika ndi zida popanda kudikirira nthawi yayitali kuti azisakaniza kapena kuziyambitsa.
Kugwiritsa ntchito mosiyanasiyana kwa ufa wa polima wotayikanso kumalimbikitsidwanso ndi mawonekedwe awo apamwamba. Kuthekera kwawo komatira kwakukulu kumawapangitsa kukhala abwino kugwiritsidwa ntchito pomanga zomata, zomatira matailosi, ndi zinthu zosiyanasiyana zomangira, zomwe zimapereka kulumikizana kolimba, kodalirika muzomangira. Kuphatikiza apo, kukana kwamadzi komwe kumapangidwa ndi ma polima a ufa kumapereka chitetezo ku kulowetsedwa kwa chinyezi, chomwe ndi chofunikira kuti zisungidwe zizikhala ndi moyo wautali komanso zolimba. Matenthedwe otenthetsera mafuta amathandizanso kuti nyumba ziziyenda bwino, zomwe zimapangitsa kukhala chisankho chodziwika bwino pakati pa omanga ndi mainjiniya omwe amayang'ana kwambiri pamayankho okhazikika. Pamene mafakitale akupitirizabe kufunafuna zipangizo zamakono kuti apititse patsogolo khalidwe lazogulitsa ndi ntchito, ntchito ya ufa wa polima wotayikanso idzakula kwambiri, ndikuwonetsetsa kufunikira kwake pakugwiritsa ntchito panopa komanso mtsogolo.
