Kusukela ngeminyaka yawo-1980s, udaka olomile oluxubile olumelelwe i-ceramic tile binder, i-caulk, i-self-flow kanye nodaka olungangeni manzi luye lwangena emakethe yaseShayina, bese kuthi ezinye izinhlobo zamazwe ngamazwe zokukhiqiza kabusha impushana zingene emakethe yaseShayina, okuholela ekuthuthukisweni kokuxutshwa okomile. udaka eChina.
Njengempahla eluhlaza engabalulekile kudaka olukhethekile lwengxube eyomile olufana ne-tile binder, udaka oluzilinganisa kanye nohlelo lokufakwa kodonga olusekela udaka, impushana ye-polymer ehlakazeka kabusha idlala indima ebalulekile ekusebenzeni kodaka olukhethekile lwengxube eyomile.Ngokombono wemakethe yomhlaba wonke, inani lempushana ye-polymer ehlakazeka kabusha belilokhu likhombisa ukukhula okuqhubekayo, ngesikhathi esifanayo, ukukhuthazwa kwezinqubomgomo zokongiwa kwamandla okwakhiwa kwasekhaya kanye nokunciphisa ukungcola, ukukhuthazwa kwezinto zokwakha eziluhlaza kanye nokwamukelwa kabanzi udaka olukhethekile oluxubene nenani elikhulu lezicelo, lukhuthaza isidingo semakethe yasekhaya sokukhula ngokushesha kwempushana ye-polymer ehlakazekayo, kusukela ngo-2007, Ezinye izinkampani zakwamanye amazwe kanye namabhizinisi asekhaya amise imigqa yokukhiqiza impushana ehlakazeka kabusha ezweni lonke.
Ngemuva kweminyaka ecishe ibe ngu-20 yentuthuko, isidingo sasekhaya se-polymer powder ehlakazeka kabusha sibonise ukukhula okuzinzile okuhambisana nokwamazwe ngamazwe, sihlanganise idatha yeminyaka emihlanu edlule, ukukhiqizwa kwe-polymer e-2013-2017 redispersible redispersible kubonise umkhuba wokukhula ozinzile, ngo-2017, ukukhiqizwa kwempushana ye-polymer yasekhaya ehlakazeka kabusha kumathani ayi-113,000, ukwanda kwe-6.6%.Ngaphambi kuka-2010, ngenxa yokukhula ngokushesha kwemakethe yezindlu ezithengiswayo, kwaholela ekwenyukeni okukhulu kwamandla emakethe ye-insulation, kodwa futhi kwaholela esidingweni esinamandla sempushana ye-latex ehlakazeka kabusha, izinkampani eziningi zatshala imali emkhakheni we-latex powder. , ukuze kuzuze izinzuzo zesikhathi esifushane, ukukhula ngokushesha kwamandla okukhiqiza, umthamo wamanje wokukhiqiza uyakhiwa ngaphambi kuka-2010. Eminyakeni yamuva, ukwehla kwemakethe yezindlu zasekhaya, ukwehla kwezindlu ezintsha zezohwebo, ukwakhiwa kanye nokugunyazwa kwephrojekthi entsha ngokuhlukahluka. ama-degrees of slowdown, abangela ngokuqondile ukwehla kwesidingo sazo zonke izinhlobo zezinto zokwakha, kodwa eminyakeni emibili edlule, imakethe yokulungiswa kwesakhiwo kancane kancane yakha isikali, kusukela kwesinye isici ukukhuthaza ukuthuthukiswa kokuziphatha okukhethekile kwengxube eyomile, kodwa futhi. kuholele ekukhuleni kwesidingo se-polymer powder esihlakazeka kabusha.
Imboni ye-polymer powder ehlakazeka kabusha ingene esikhathini sokulungisa ngemva kuka-2012, iphethini entsha yokuncintisana yezimboni iye yakha kancane kancane, imakethe ingene esigabeni sokuthuthuka esizinzile, futhi amandla okukhiqiza we-polymer powder aphinde ahlala ezinzile.Ngenxa yegebe elikhulu phakathi kwamandla okukhiqiza kanye nesidingo, kuhambisana nezindleko ezinengqondo kanye nokulawulwa kwenzuzo, intengo ye-latex powder ehlakazeka kabusha ibilokhu yehla, futhi intengo yempushana ye-latex ehlakazeka kabusha emakethe yasekhaya ibilokhu yehla ngonyaka unyaka kusuka ku-2013 kuya ku-2017. Ngo-2017, inani lentengo ye-latex powder emabhizinisini asekhaya yi-14 RMB/kg, inani lentengo ye-latex powder yangaphandle yi-16 RMB / kg, futhi igebe lentengo yomkhiqizo wamabhizinisi asekhaya nakwamanye amazwe liyancipha. unyaka nonyaka, ikakhulukazi ngenxa yokuthuthukiswa kobuchwepheshe bokukhiqiza bamabhizinisi asekhaya, ukuqiniswa kwekhono lokusungula elizimele lomkhiqizo, kanye nokuthuthukiswa kwezinga lekhwalithi yempushana ye-polymer ehlakazeka kabusha.
Njengamanje, imboni yasekhaya ye-emulsion powder isiqalile ukubonakala, futhi kusekhona igebe elithile phakathi kwamabhizinisi okukhiqiza asekhaya kanye namazwe athuthukile kwezobuchwepheshe bokukhiqiza kanye nemishini, ukutshalwa kwezimali kocwaningo nokuthuthukiswa, ikhwalithi yomkhiqizo, kanye nokuthuthukiswa kwesicelo, okubuye kube nokuthuthukiswa komkhiqizo. isici esiyinhloko esithinta futhi sikhawulela ukuthuthukiswa okunempilo komkhakha we-emulsion powder ohlakazeka kabusha.I-emulsion powder yomkhiqizo wasekhaya i-redispersible emulsion powder ayizange ibe umholi wemakethe, isizathu esiyinhloko ukuntuleka kwamandla ezobuchwepheshe amabhizinisi asekhaya, ukuphathwa okungezona okujwayelekile, ukuqina komkhiqizo ompofu, izinhlobo ezingashadile.
Uma kuqhathaniswa namanye amaphrojekthi amakhemikhali, isikhathi sokwakhiwa kwamaphrojekthi wempuphu ye-polymer ehlakazeka kabusha sifushane futhi umkhiqizo usetshenziswa kabanzi, ngakho-ke kukhona isenzakalo sokuncintisana okungahlelekile embonini.Ngaphezu kwalokho, ngenxa yokuntuleka kwamazinga emboni kanye nezinkambiso zemakethe ezilandelwa abakhiqizi bakadaka, kunamabhizinisi amancane kakhulu anezinga eliphansi lobuchwepheshe kanye nokutshalwa kwezimali okulinganiselwe embonini, lawa mabhizinisi anezinkinga zokungcoliswa kwemvelo ohlelweni lokukhiqiza, futhi aphansi. izindleko kanye nomthelela wamanani aphansi wekhwalithi ephansi kanye nokutshalwa kwezimali okuphansi kokuvikelwa kwemvelo kungahlakazwa kabusha imakethe yempuphu ye-latex.Ngenxa yalokho, imakethe igcwele imikhiqizo eminingi engafanelekile nengajwayelekile, futhi ikhwalithi ayilingani.Ngesikhathi esifanayo, amanye amabhizinisi ukuze ahlangabezane nezidingo zamakhasimende, afune ukukhulisa izinzuzo ezisheshayo, athathe ukuziphatha kwesikhashana ngezindleko zekhwalithi yomkhiqizo, ikakhulukazi eminyakeni emibili edlule, imikhiqizo eminingi ehlanganisiwe endaweni yemakethe ye-polymer powder , ngemikhiqizo evamile ngokubukeka ayikwazi ukuhlukaniswa ngokucacile, ukuhlolwa okulula endaweni nakho kungadlula, intengo yomkhiqizo iphansi kakhulu.Kodwa-ke, ukuqina kwayo akulungile, futhi ngemva kokwengeza uhlelo lomkhiqizo wokufakwa odongeni lwangaphandle nokulusebenzisa odongeni, kuzoba nezinkinga zekhwalithi phakathi nezinyanga ezimbili noma ezintathu.
Ngasikhathi sinye, siyabona futhi ukuthi ngenxa yokwenzeka njalo kwezingozi zokuphepha ezifana nokuwa kwamathayela odonga kanye ne-formaldehyde ngokweqile okubangelwa izinkinga zekhwalithi yomkhiqizo eminyakeni yamuva nje, ukukhathazeka komphakathi ngokuphepha kwendawo okuhlala kuyo kanye nokuthuthukiswa kwezinkinga ezifanele. imithetho kahulumeni, ukugadwa komkhiqizo kuzokhula, futhi imboni ye-polymer powder ehlakazeka kancane kancane izodlulela esigabeni sokuthuthuka esinempilo nesimeme.
