I-Emulsion kanye ne-latex evuselelayo ye-latex ingakha amandla aphezulu ashubile namandla okubopha ngezinto ezihlukile ngemuva kokwakheka kwefilimu, asetshenziswa njenge-tinder yesibili ngodaka ukuze ahlanganiswe nosimende wokuhlanganisa i-inorganic, asetshenziswe usimende ngokulandelana anikeza ukudlala okugcwele kumandla ahambisanayo ukuthuthukisa i ukusebenza kodaka.
Ngokubona impahla ye-microsmmer-cement composite impahla, kukholelwa ukuthi ukwengeza i-latex evuselelayo ye-latex kungenza i-polymer yakha ifilimu futhi ibe yingxenye yodonga lomgodi, okuthuthukisa amandla angaphakathi lodaka. Amandla we-polymer, ngaleyo ndlela athuthukise ukucindezela ukwehluleka kodaka nokwandisa ubunzima bokugcina.
I-microssmctor ye-polymer ku-mende kasimende ayikashintshi isikhathi eside, futhi igcina ubuhlobo obuzinzile, amandla aguqukayo nangokucindezela, kanye ne-hydrophophobicity enhle. Indlela yokwakheka ye-latex evuselelayo ye-latex powder ngamandla anama-adhesives athola ukuthi ngemuva kokuthi i-polymer yomile kwifilimu, i-polymer film yakha ukuxhumana okuguqukayo phakathi kodaka kanye nethayili ngakolunye uhlangothi, ngakolunye uhlangothi, i-polymer in Udaka olusha lukhulisa okuqukethwe komoya kodaka futhi kuthinta ukwakheka nokugqekeza kobuso, bese ngesikhathi senqubo yokusetha, i-polymer nayo inethonya elingcono kwinqubo ye-hydration, okuzonikela Kumandla webhondi yokuthuthukisa unosizo olungcono.
Ukungeza i-latex ye-latex evuselelayo ku-dolor kungathuthukisa kakhulu amandla okubopha nezinye izinto, ngoba i-hydrophilic latex puleza ingena kuma-matrix kanye ne-capillaries ye-matrix, futhi i-latex powder ingena kuma-pores kanye nama-capillaries . Ifilimu langaphakathi yakhiwa futhi ihlanganiswe ngokuqinile ebusweni be-substrate, ngaleyo ndlela iqinisekise amandla amakhulu obuhlobo phakathi kwezinto eziqinisekisiwe kanye ne-substrate.
Ukusebenziseka kwe-latex powder ekusebenzeni ngodaka kungenxa yokuthi i-latex powder iyi-polymer ephezulu yama-moleculate enamaqembu ama-polar. Lapho i-latex powder ihlanganiswa ne-EPS izinhlayiya, ingxenye engeyona i-polar ku-main chain ye-latex powmer polymer izokwenzeka ngobuso be-eps. Amaqembu ama-polar e-polymer athambekele ngaphandle ebusweni bezinhlayiya ze-EPS, ukuze izinhlayiya ze-EPS ziguqukele kusuka ku-hydrophobicity ku-hydropholity. Ngenxa yokuguqulwa kobubanzi bezinhlayiya ze-EPS nge-latex powder, ixazulula inkinga ukuthi izinhlayiya ze-EPS zivezwa kalula emanzini. Intanta, inkinga yokugcwala okukhulu kodaka. Ngalesi sikhathi, lapho kufakwa usimende futhi kuxutshwe, amaqembu ama-polar adderbed ebusweni bezinhlayiya ze-EPS axhumana nezinhlayiya ze-EPS futhi ahlanganise eduze, ukuze ukusebenziseka kodumo kudunyiswa kwe-EPS kwenziwa ngcono. Lokhu kuboniswa eqinisweni lokuthi izinhlayiya ze-EPS zimanzi kalula ngokonasi kasimende, futhi amabutho aphakathi kwalezi ezimbili athuthukiswa kakhulu.
