I-Redispersible latex powder yi-polymer powder enokuphinda ichitheke emanzini. Isetyenziswa njengesongezelelo kwizixhobo zokwakha ezifana neemortar, ii-tile adhesives kunye nee-grouts. I-Redispersible latex powder isebenza njenge-binder, inika ukunamathela okuhle kakhulu kwaye iphucula iipropati zemveliso yokugqibela. Eli nqaku liza kugxila kwindlela ukusetyenziswa kwe-redispersible polymer powder enokuphucula ngayo impembelelo kunye nokumelana nokukrala kwe-mortar.
Ukumelana neempembelelo
Ukumelana neempembelelo yindlela yokulinganisa amandla ezinto zokumelana neempembelelo ngequbuliso ngaphandle kokuqhekeka okanye ukuqhekeka. Kwi-mortar, ukumelana neempembelelo luphawu olubalulekileyo, kuba iya kuba neempembelelo ezahlukeneyo ngexesha lokwakhiwa nokusetyenziswa. I-mortar kufuneka ibe namandla ngokwaneleyo ukumelana neempembelelo ngaphandle kokuqhekeka kwaye ibeke emngciphekweni ulwakhiwo lwesakhiwo okanye umphezulu.
Iipowder zepolymer eziphinda zichithwe ziphucula ukumelana nefuthe lemortar ngeendlela ezahlukeneyo. Okokuqala, ziphucula ukuhlangana kwemortar. Xa zongezwa kwimortar, ii-particles zepolymer powder eziphinda zichithwe zisasazwa ngokulinganayo kulo lonke umxube, zenze ikhonkco eliqinileyo kodwa eliguquguqukayo phakathi kwee-particles zesanti kunye nesamente. Oku kuqinisa ukuhlangana kwemortar, okwenza ukuba imelane nokuqhekeka nokuqhekeka xa ichaphazeleka.
I-matrix ye-mortar eqinisiweyo ye-latex powder ephinda idispozwe. Amasuntswana e-polymer kwi-powder asebenza njengeebhulorho phakathi kwee-aggregates, egcwalisa izikhewu kwaye edala unxibelelwano oluqinileyo phakathi kwamasuntswana esanti kunye nesamente. Olu qiniso lubonelela ngokumelana okongezelelweyo nokuchaphazeleka, okuthintela ukuphuhliswa kwemingxunya kunye nokuqhekeka.
Umgubo welatex ophinda uqhekeke wongeza ukuguquguquka kunye nokuthamba kwemotha. Amasuntswana epolymer akumgubo aphucula amandla emotha okolula nokugoba, efunxa amandla okubetha ngaphandle kokuqhekeka. Oku kuvumela imotha ukuba ijike kancinci phantsi koxinzelelo, kunciphisa amathuba okuba kubekho imifantu.
ukumelana nokuguguleka
Ukumelana nokukrala yenye into ebalulekileyo yesamente. I-mortar isetyenziswa kakhulu njengezinto eziphezulu, nokuba kukugqitywa okubonakalayo okanye njenge-underlayment kwezinye izinto ezifana nethayile okanye ilitye. Kwezi meko, isamente kufuneka ihlale ixesha elide kwaye imelane nokuguguleka, ukukrala kunye nokukhukuliseka.
Umgubo wepolymer ophinda uqhekeke unokuphucula ukumelana nokurhawuzelelwa kodaka ngeendlela ezahlukeneyo. Okokuqala, kunceda ekunciphiseni ukurhawuzelelwa kodaka. Ukurhawuzelelwa yingxaki eqhelekileyo kwizinto ezisekwe kwisamente, okubangela ukuqhekeka kunye nokukhukuliseka kancinci komphezulu. Ukongezwa komgubo wepolymer ophinda uqhekeke kunciphisa ubungakanani bokurhawuzelelwa, kuqinisekisa ukuba udaka lugcina ulungelelwano lwalo lwesakhiwo kwaye luhlala luxhathisa ukuguguleka.
Umgubo welatex ophinda udibane uphucula ukunamathela komongo kwi-substrate. Amasuntswana epolymer akumongo enza umanyano oluqinileyo ne-substrate, nto leyo ethintela umongo ukuba ungaphakami okanye ungawi kumphezulu xa ungcoliswa. Oku kwandisa ukuqina komongo, kuqinisekisa ukuba unamathela ngokuqinileyo kwi-substrate kwaye uyamelana nokukhukuliseka.
Umgubo welatex ophinda uqhekeke wonyusa ukuguquguquka kunye nokuthamba kwemortar. Njengokumelana nokuchaphazeleka, ukuguquguquka kunye nokuthamba kwemortar kudlala indima ebalulekileyo ekumelaneni nokurhawuzelelwa. Amasuntswana epolymer kwipowder andisa amandla emortar okuguquka phantsi koxinzelelo kwaye afunxe amandla okuguguleka ngaphandle kokuqhekeka okanye ukuqhekeka.
Umgubo wepolymer ophinda uqhekeke sisongezelelo esisebenza ngeendlela ezininzi esinokuphucula ukusebenza kwe-mortar. Siphucula ukuhambelana, ukuqina, ukuguquguquka kunye nokuqina kwe-mortar, nto leyo eyenza ukuba ibe sisixhobo esibalulekileyo sokuphucula ukumelana nempembelelo kunye nokukrweleka.
Ngokusebenzisa umgubo wepolymer osasazekayo kwi-mortar yabo, abakhi kunye nabakhi banokuqinisekisa ukuba izakhiwo zabo ziqinile, zihlala ixesha elide kwaye azigugi. Oku kwandisa ixesha elide lesakhiwo, kunciphisa iindleko zokugcinwa kunye nokuphucula ukhuseleko ngokubanzi.
Lilonke, ukusetyenziswa kweepowder zepolymer ezisasazekayo luphuhliso oluhle kwishishini lokwakha, olubonelela ngendlela esebenzayo nefikelelekayo yokuphucula ukusebenza kweemortar kunye nokuqinisekisa izakhiwo ezihlala ixesha elide.
