Ukusukela ngeminyaka yoo-1980, udaka olomileyo oluxubeneyo olumelwe yithayile yethayile yokubopha, i-caulk, ukuqukuqela kunye nodaka olungenamanzi luye lwangena kwimarike yaseTshayina, emva koko ezinye iibrendi zamanye amazwe amashishini okuvelisa umgubo aphinde adispersible aphinde angena kwimarike yaseTshayina, ekhokelela kuphuhliso lomxube owomileyo. udaka eTshayina.
Njengemathiriyeli ekrwada eyimfuneko kudaka olukhethekileyo lomxube owomileyo olufana ne-tile binder, i-self-leveling mortar kunye nenkqubo yokugquma eludongeni exhasa udaka, umgubo wepolymer odispersible udlala indima ebalulekileyo ekusebenzeni kodaka olukhethekileyo lomxube owomileyo.Ngokombono wemarike yehlabathi, inani le-polymer powder elidispersible libonisa ukukhula okuzinzileyo, ngexesha elifanayo, ukukhuthazwa kokugcinwa kwamandla okwakhiwa kwekhaya kunye nemigaqo-nkqubo yokunciphisa ukukhutshwa, ukukhuthazwa kwezinto zokwakha eziluhlaza kunye nokwamkelwa ngokubanzi udaka olukhethekileyo lomxube owomileyo kunye nenani elikhulu lezicelo, ukukhuthaza imfuno yemarike yasekhaya yokukhula ngokukhawuleza komgubo wepolymer, ukusukela ngo-2007, Ezinye iinkampani zamazwe angaphandle kunye namashishini asekhaya aseke imigca yokuvelisa umgubo wepolymer enokuphinda ihlakazwe kulo lonke ilizwe.
Emva kweminyaka ephantse ibe yi-20 yophuhliso, imfuno yasekhaya ye-polymer powder edispersible ibonise ukukhula okuzinzileyo okuhambelana nezizwe ngezizwe, siye sadibanisa idatha yeminyaka emihlanu edlulileyo, i-2013-2017 i-redispersible powder powder production ibonise ukukhula okuzinzileyo, in 2017, imveliso yasekhaya redispersible ipolymer umgubo 113.000 tons, ukwanda 6.6%.Phambi kuka-2010, ngenxa yokukhula ngokukhawuleza kwemarike yezindlu zasekhaya, kukhokelele ekwenyukeni okukhulu komthamo wentengiso yokugquma, kodwa kwakhona kukhokelele kwimfuno eyomeleleyo yomgubo we-latex odispersible, iinkampani ezininzi zityale imali kwintsimi yomgubo welatex ophinda-phindayo. , ukuze kuzuze inzuzo yexesha elifutshane, ukukhula ngokukhawuleza kwamandla okuvelisa, amandla okuvelisa angoku akhiwe ngaphambi kowama-2010. Kwiminyaka yakutshanje, ukuhla kwemarike yezindlu zasekhaya, ukuhla kwezindlu ezintsha zorhwebo, ukwakhiwa kunye nokuvunywa kweprojekthi entsha ngokungafaniyo. iqondo lokucotha, ngokuthe ngqo kubangele ukucotha kwemfuno yazo zonke iintlobo zezinto zokwakha, kodwa kule minyaka mibini idlulileyo, imarike yokulungiswa kwesakhiwo ngokuthe ngcembe yenza isikali, ukusuka komnye umba wokukhuthaza uphuhliso lokuziphatha okukhethekileyo kodaka lomxube owomileyo, kodwa kwakhona. ikhokelele ekukhuleni kwemfuno yomgubo wepolymer enokuphinda ihlakazwe.
Ishishini le-polymer enokuchithwa kwakhona lingene kwixesha lohlengahlengiso emva kwe-2012, ipateni entsha yokhuphiswano loshishino iye yaqulunqwa ngokuthe ngcembe, imarike ingene kwinqanaba lophuhliso oluzinzile, kwaye amandla okuvelisa i-polymer powder ahlala ehleli.Ngenxa yomsantsa omkhulu phakathi komthamo wemveliso kunye nemfuno, idityaniswe nexabiso eliqiqileyo kunye nolawulo lwenzuzo, ixabiso le-latex powder elihlanjululwayo liye lehla, kwaye ixabiso le-latex powder ehlanjululwayo kwimarike yasekhaya liye lehla ngonyaka. unyaka ukusuka kwi-2013 ukuya ku-2017. Kwi-2017, ixabiso eliqhelekileyo le-latex powder kumashishini asekhaya li-14 RMB / kg, ixabiso eliqhelekileyo le-brand brand latex powder liyi-16 RMB / kg, kwaye i-gap yexabiso lemveliso yamashishini asekhaya nakwamanye amazwe ayancipha. unyaka nonyaka, ikakhulu ngenxa yokuphuculwa kobuchwephesha bemveliso yamashishini asekhaya, ukomelezwa kwesakhono sokwenza izinto ezizimeleyo kwimveliso, kunye nokuphuculwa komgangatho wepolymer powder.
Okwangoku, ishishini lasekhaya redispersible emulsion powder sele iqalile ukuthatha imilo, kwaye kusekho umsantsa othile phakathi kwamashishini imveliso yasekhaya kunye namazwe aphuhlileyo kubugcisa imveliso kunye nezixhobo, uphando kunye nophuhliso utyalo-mali, umgangatho imveliso, kunye nophuhliso isicelo, nto leyo nayo. eyona nto iphambili echaphazelayo kwaye ithintele uphuhliso olusempilweni lweshishini le-emulsion powder eliphinda liphindwe kabini.I-brand brand redispersible emulsion powder ayizange ibe yinkokeli yemarike, esona sizathu sisisiseko kukunqongophala kwamandla obugcisa kumashishini asekhaya, ulawulo olungenamgangatho, ukuzinza kwemveliso embi, iintlobo ezizodwa.
Xa kuthelekiswa nezinye iiprojekthi zeekhemikhali, ixesha lokwakhiwa kweeprojekthi ze-polymer powder ezihlaziywayo lifutshane kwaye imveliso isetyenziswa ngokubanzi, ngoko kukho into yokhuphiswano olungahambi kakuhle kwishishini.Ukongeza, ngenxa yokunqongophala kwemigangatho yoshishino kunye nemilinganiselo yentengiso ethotyelwe ngabavelisi bodaka, kukho uninzi lwamashishini amancinci anenqanaba eliphantsi lobuchwephesha kunye notyalo-mali olulinganiselweyo kwishishini, la mashishini aneengxaki zongcoliseko lokusingqongileyo kwinkqubo yokuvelisa, kunye nenqanaba eliphantsi ixabiso kunye nempembelelo yexabiso eliphantsi lomgangatho ophantsi kunye notyalo-mali oluphantsi lokukhuselwa kwendalo lunokusasazwa kwakhona imarike ye-latex powder.Ngenxa yoko, imarike izaliswe ziimveliso ezininzi ezingafanelekanga nezingekho semgangathweni, kwaye umgangatho awulingani.Kwangaxeshanye, amanye amashishini ukuze ahlangabezane neemfuno zabathengi, afune ukwandisa inzuzo ekhawulezileyo, athathe isimilo sexesha elifutshane ngeendleko zomgangatho wemveliso, ngakumbi kule minyaka mibini idlulileyo, iimveliso ezininzi ezidityanisiweyo kwimarike yomgubo wepolymer yasekhaya. , ngeemveliso eziqhelekileyo ngenkangeleko azikwazi ukwahlula ngokucacileyo, uvavanyo olulula kwi-site nalo lungadlula, ixabiso lemveliso liphantsi.Nangona kunjalo, ukuqina kwayo kubi, kwaye emva kokongeza inkqubo yemveliso yodonga lwangaphandle kunye nokuyisebenzisa eludongeni, kuya kubakho iingxaki ezisemgangathweni kwiinyanga ezimbini okanye ezintathu.
Kwangaxeshanye, sibona kwakhona ukuba ngenxa yokwenzeka rhoqo kweengozi zokhuseleko ezifana neethayile zodonga eziwayo kunye ne-formaldehyde egqithisileyo ebangelwa yingxaki yomgangatho wemveliso kwiminyaka yakutshanje, inkxalabo yoluntu malunga nokhuseleko lwendawo yokuhlala kunye nokuphuculwa kwezinto ezifanelekileyo. Imimiselo ngurhulumente, ukulawulwa kwemveliso kuya kwanda, kwaye ishishini lomgubo wepolymer linokuphinda liqhubele phambili ngokuthe ngcembe liye kwinqanaba lophuhliso olunempilo noluzinzileyo.
