Kuyambira m'ma 1980, matope osakanikirana omwe amaimiridwa ndi matailosi a ceramic binder, caulk, self-flow and waterproof matope alowa mumsika wa China, ndiyeno mabizinesi ena apadziko lonse a mabizinesi opangira ufa alowa mumsika waku China, akutsogolera kukula kwa matope owuma osakanikirana ku China.
Monga zopangira zofunika kwambiri mumtondo wapadera wosakaniza wowuma monga matailosi omangira, matope odziyimira pawokha komanso makina otchinjiriza pakhoma othandizira matope, ufa wopangidwanso wa polima umakhala ndi gawo lofunikira popanga matope apadera owuma. Msika wapadziko lonse lapansi, kuchuluka kwa ufa wa polima wa redispersible kwakhala kukuwonetsa kukula kokhazikika, nthawi yomweyo, kulimbikitsa chitetezo chanyumba zoweta komanso mfundo zochepetsera mpweya, kulimbikitsa zida zomangira zobiriwira komanso kuvomereza kwakukulu kwamatope apadera owuma komanso ntchito zambiri, kulimbikitsa msika wapakhomo wa redispersible polima polima polima polima, kuyambira makampani ena akunja. mizere yopangira ufa wa polima m'dziko lonselo.
Patatha zaka pafupifupi 20 chitukuko, zoweta ankafuna redispersible polima ufa wasonyeza khola kukula mchitidwe lolingana ndi mayiko, ife Integrated deta zaka zisanu zapitazi, 2013-2017 redispersible polima ufa kupanga anasonyeza ndi khola kukula azimuth, mu 2017, zoweta redispersible polima, 613 ufa, kuwonjezeka 6000% 1. Chaka cha 2010 chisanafike, chifukwa cha kukula kwachangu kwa msika wanyumba zoweta nyumba, zidapangitsa kuti msika wotchinjiriza uwonjezeke, komanso kudapangitsa kuti pakhale kufunikira kwamphamvu kwa ufa wa latex, makampani ambiri adayikapo gawo la ufa wa latex, kuti apindule kwakanthawi, kukula mwachangu kwamphamvu yopanga, kukula kwa msika wamakono kumatsika, msika wapakhomo usanayambike zaka 20 zaposachedwa. nyumba malonda, yomanga ndi chivomerezo latsopano ntchito mu madigiri osiyanasiyana a slowdown, mwachindunji anachititsa kuchepa kwa kufunika kwa mitundu yonse ya zipangizo zomangira, koma m'zaka ziwiri zapitazi, nyumba kukonzanso msika pang'onopang'ono anapanga sikelo, kuchokera mbali ina kulimbikitsa chitukuko cha wapadera youma Kusakaniza matope khalidwe, komanso zinachititsa kuti redispersible polima ufa kufunika kukula.
The redispersible polima ufa makampani walowa nthawi kusintha pambuyo 2012, latsopano makampani mpikisano chitsanzo pang'onopang'ono aumbike, msika walowa siteji khola chitukuko, ndi mphamvu yopanga redispersible polima ufa wakhalanso okhazikika. Chifukwa cha kusiyana kwakukulu pakati pa mphamvu zopangira ndi zofuna, kuphatikizapo mtengo wamtengo wapatali ndi ndondomeko ya phindu, mtengo wa redispersible latex ufa wakhala ukutsika, ndipo mtengo wa redispersible latex ufa pamsika wapakhomo wakhala ukutsika chaka ndi chaka kuyambira 2013 mpaka 2017. yachilendo mtundu latex ufa ndi 16 RMB/kg, ndipo kusiyana kwa mtengo wa malonda a m'banja ndi akunja akucheperachepera chaka ndi chaka, makamaka chifukwa cha luso kupanga mabizinesi apakhomo, kulimbikitsa mankhwala odziimira luso luso, ndi kusintha mlingo wa khalidwe la redispersable polima ufa.
Pakali pano, zoweta redispersible emulsion ufa mafakitale wayamba kuoneka, ndipo pali kusiyana pakati pa mabizinezi zoweta kupanga ndi mayiko otukuka mu luso kupanga ndi zipangizo, ndalama kafukufuku ndi chitukuko, mankhwala khalidwe, ndi chitukuko ntchito, amenenso ndi chinthu chachikulu zimakhudza ndi kuletsa chitukuko cha thanzi la redispersible emulsion ufa makampani. The zoweta mtundu redispersible emulsion ufa sanakhale mtsogoleri msika, chifukwa chachikulu ndi kusowa luso luso mabizinezi zoweta, sanali muyezo kasamalidwe, osauka mankhwala bata, limodzi mitundu.
Poyerekeza ndi mapulojekiti ena amankhwala, nthawi yomanga mapulojekiti a ufa wa polima wopangidwanso ndi yaifupi ndipo mankhwalawa amagwiritsidwa ntchito kwambiri, chifukwa chake pali chodabwitsa champikisano wosasamala pamsika. Kuphatikiza apo, chifukwa cha kusowa kwa miyezo yamakampani ndi mayendedwe amsika omwe amatsatiridwa ndi opanga matope, pali mabizinesi ang'onoang'ono omwe ali ndi luso lochepa laukadaulo komanso ndalama zocheperako pamsika, mabizinesiwa ali ndi zovuta zowononga chilengedwe popanga, komanso kutsika mtengo komanso kutsika kwamitengo yotsika komanso kutsika kwachitetezo cha chilengedwe kumatha kubalalitsidwanso msika wa latex ufa. Zotsatira zake, msika umadzazidwa ndi zinthu zambiri zosayenera komanso zosavomerezeka, ndipo khalidweli ndi losiyana. Nthawi yomweyo, mabizinesi ena kuti akwaniritse zosowa zamakasitomala, amafunafuna kukulitsa zopindulitsa nthawi yomweyo, amatenga nthawi yayitali motengera mtundu wazinthu, makamaka m'zaka ziwiri zapitazi, zinthu zambiri zapawiri zopezeka m'misika yamsika yopangidwanso ndi polima polima, ndi zinthu wamba m'mawonekedwe sangasiyanitsidwe momveka bwino, kuyezetsa kosavuta pamalowo kumathanso kutha, mtengo wamankhwala ndi wotsika kwambiri. Komabe, kulimba kwake kumakhala kocheperako, ndipo mutatha kuwonjezera zida zakunja zopangira khoma ndikuziyika pakhoma, padzakhala zovuta pamiyezi iwiri kapena itatu.
Nthawi yomweyo, tikuwonanso kuti chifukwa cha zochitika pafupipafupi za ngozi zachitetezo monga matailosi apakhoma akugwa ndi formaldehyde mopitilira muyeso chifukwa cha zovuta zamtundu wazinthu m'zaka zaposachedwa, nkhawa ya anthu pachitetezo cha chilengedwe komanso kuwongolera malamulo oyenerera ndi boma, kuyang'anira mankhwala kudzawonjezeka, ndipo makampani opanga ufa wopangidwa ndi polima adzapita pang'onopang'ono kupita ku gawo lachitukuko lathanzi komanso lokhazikika.
