Udindo waredispersible polima ufamukumangamakampani sanganyalanyazidwe.Monga chowonjezera chogwiritsidwa ntchito kwambiri, tinganene kuti mawonekedwe a ufa wa polima wopangidwanso wasintha bwino ntchito yomanga ndi kalasi yopitilira imodzi.Chigawo chachikulu cha redispersible polima ufa ndi organic macromolecular polima ndi katundu wokhazikika.Nthawi yomweyo, PVA imawonjezedwa ngati colloid yoteteza.Nthawi zambiri imakhala yaufa kutentha kwapakati.Kukhoza kumamatira ndi kolimba kwambiri ndipo ntchito yomanga ndi yabwino kwambiri.Kuphatikiza apo, mtundu uwu wa ufa wa polima ukhoza mwachiwonekere kupititsa patsogolo kukana komanso kuyamwa madzi pakhoma popititsa patsogolo mgwirizano wamatope.Panthawi imodzimodziyo, mphamvu ya mgwirizano ndi kupunduka ndizotsimikizika.digiri ya kuwongolera.
Redispersible latex ufandi wobiriwira, chilengedwe wochezeka, kumanga mphamvu yopulumutsa, apamwamba Mipikisano zolinga ufazomangira, ndipo ndi chofunikira komanso chofunikira kwambiri chogwirira ntchitomatope osakaniza owuma.Ikhoza kupititsa patsogolo ntchito ya matope, kuonjezera mphamvu ya matope, kuonjezera mphamvu zomangirira pakati pa matope ndi magawo osiyanasiyana, kupititsa patsogolo kusinthasintha ndi kugwira ntchito, mphamvu zopondereza, mphamvu zosinthika, kukana kuvala, kulimba, ndi kukhuthala kwamatope.Relay ndi mphamvu posungira madzi, constructability.Kuchita kwa redispersible latex powder muzomatira matailosindi wamphamvu, ndipo redispersible latex ufa ali mkulu kugwirizana luso ndi wapadera katundu.
Latex ufakumapangitsa kusinthasintha ndi kusalala kwa dongosolo mu chikhalidwe chonyowa chosakanikirana.Chifukwa cha makhalidwe a polima, kugwirizanitsa kwa zinthu zosakaniza zonyowa kumakula bwino, ndipo kumathandizira kwambiri kuti zitheke;pambuyo kuyanika, amaperekakumamatira kwa wosanjikiza wosalala ndi wandiweyani pamwamba, Sinthani mawonekedwe mawonekedwe a mchenga, miyala ndi pores.Pansi pa malo owonetsetsa kuchuluka kwa kuonjezera, akhoza kulemeretsedwa mu filimu pa mawonekedwe, kotero kuti zomatira matailosi kukhala ndi kusinthasintha kwina, amachepetsa zotanuka.odulus, ndipo imayamwa kupsinjika kwa kutentha kwambiri.Pankhani yomizidwa m'madzi pambuyo pake, padzakhala zovuta monga kukana madzi, kutentha kwa bafa, ndi kusinthika kwa zinthu zosagwirizana (matayilo opindika 6 × 10-6/℃, kokwanira konkire ya simenti 10 × 10-6 / ℃) , ndikuwongolera kupirira kwanyengo.
Kuphatikizika kwa ufa wa latex wopangidwanso mu zomatira za matailosi kumakhala ndi zotsatira zoonekeratu pakuwongolera magwiridwe antchito a zomatira za simenti, ndipo zimakhudza kwambiri mphamvu yomangirira, kukana madzi, komanso kukana kukalamba kwa zomatira.Pali mitundu yambiri ya ufa wonyezimira wa latex wopangira zomatira pamatailosi pamsika, monga acrylic redispersible latex powder, styrene-acrylic powder, vinilu acetate-ethylene copolymer, ndi zina zambiri. .Ambiri mwa ufa wa latex wotayika ndivinyl acetate-ethylene copolymer.
(1) Pamene kuchuluka kwa simenti kumawonjezeka, mphamvu yapachiyambi ya ufa wa latex wopangidwanso wowonjezera matailosi imawonjezeka, ndipo nthawi yomweyo, mphamvu zomatira zomata pambuyo pa kumizidwa m'madzi ndi mphamvu zomatira pambuyo pa ukalamba wa kutentha zimawonjezeka.
(2) Ndi kuwonjezeka kwa kuchuluka kwa ufa wa latex wopangidwanso wa zomatira za matailosi, mphamvu yomangira yolumikizira matailosi ya ufa wothira matailosi pambuyo pa kumizidwa m'madzi ndi mphamvu yomangika pambuyo pokalamba kutentha idakula molingana, koma kukalamba kotentha Pambuyo pake. , mphamvu ya mgwirizano wokhazikika inakula kwambiri.
Njira yophatikizira matailosi ndi njira yomangira yokhuthala, ndiye kuti, choyamba ikani matope wamba kumbuyo kwa matailosi, kenako ndikusindikiza matailosi kumunsi.Makulidwe a matope wosanjikiza ndi pafupifupi 10 mpaka 30mm.Ngakhale njira imeneyi ndi yabwino kwambiri yomanga pa maziko osagwirizana, kuipa ndi otsika dzuwa lakuyika matayala, zofunika kwambiri za luso la ogwira ntchito, chiopsezo chowonjezereka cha kugwa chifukwa cha kusasinthasintha kwamatope, ndi kuvutika kukonza matope pamalo omanga.Ubwino umayendetsedwa mosamalitsa.Njirayi ndi yoyenera kwa matailosi okhala ndi kuchuluka kwa mayamwidwe amadzi.Musanaphatikize matailosi, matailosi ayenera kuviikidwa m'madzi kuti apeze mphamvu zokwanira zomangira.
