Iputty eludongeni lwangaphakathi nangaphandle, i-adhesive yethayile, i-agent ekhomba i-tile, i-agent eyomileyo yokudibanisa i-ejenti, i-thermal insulation mortar yangaphandle yeendonga zangaphandle, i-self-leveling mortar, udaka lokulungisa, udaka lokuhombisa, udaka olungangeni manzi lwangaphandle lwe-thermal edibeneyo eyomileyo exutywe nodaka.
Kumda, kukuphucula i-brittleness, imodyuli ephezulu e-elastiki kunye nobunye ubuthathaka bodaka lwesamente lwemveli, kunye nokunika udaka lwesamente ngokuguquguquka okungcono kunye namandla okuqina kwebhondi, ukwenzela ukuxhathisa kunye nokulibazisa ukuveliswa kweentanda zodaka lwesamente.Ekubeni i-polymer kunye nodaka lwenza i-interpenetrating network structure, ifilimu ye-polymer eqhubekayo yenziwa kwiipores, eyomeleza ukudibanisa phakathi kwee-aggregates kunye neebhloko ezinye ii-pores kumdaka, ngoko udaka olulungisiweyo emva kokuqina lungcono kunodaka lwesamente.Kukho uphuculo olukhulu.
Indima ye-latex powder enokuphinda isetyenziswe kwi-putty ikakhulu kule miba ilandelayo:
1. Ukuphucula i-adhesion kunye ne-mechanical properties of putty.I-redispersible latex powder yi-adhesive powder eyenziwe kwi-emulsion ekhethekileyo (i-polymer ephezulu ye-molecular) emva kokumisa isitshizi.Lo mgubo unokukhawuleza ukusabalalisa kwi-emulsion emva kokuqhagamshelana namanzi, kwaye uneempawu ezifanayo njenge-emulsion yokuqala, oko kukuthi, inokwenza ifilimu emva kokuba amanzi aphuke.Le filimu inokuguquguquka okuphezulu, ukuchasana kwemozulu ephezulu kunye nokuchasana neentlobo ezahlukeneyo zokubambelela kwi-substrates.Ukongeza, i-hydrophobic latex powder inokwenza udaka lungangeni manzi kakhulu.
2. Ukuphucula ukudityaniswa kwe-putty, ukuchasana okugqwesileyo, ukuxhathisa kwe-alkali, ukuxhathisa ukunxiba, kunye nokuphucula amandla e-flexural.
3. Ukuphucula ukungangeni kwamanzi kunye nokungena kwe-putty.
4. Ukuphucula ukugcinwa kwamanzi kwi-putty, ukwandisa ixesha elivulekileyo, kunye nokuphucula ukusebenza.
5. Ukuphucula ukuxhathisa kwempembelelo ye-putty kunye nokwandisa ukuqina kwe-putty.
2. Indima ye-latex powder edispersible kwi-adhesive tile ikakhulu kule miba ilandelayo:
1. Njengoko inani le-samente landa, amandla okuqala okunamathela kwi-tile ayanda.Kwangaxeshanye, ukomelela okuncamathelayo okuqinileyo emva kokuntywiliselwa emanzini kunye nokomelela okuncamathelayo okuqinileyo emva kokuguga kobushushu nako kuyanda.Isixa sesamente kufuneka sibe ngaphezu kwama-35%.
2. Ngokunyuka komthamo we-latex powder ohlaziywayo, amandla e-tensile bond emva kokucwina emanzini kunye nokuqina kokuqina kwebhondi emva kokuguga kwe-thermal ye-adhesive ye-tile yonyuka ngokufanelekileyo, kodwa amandla e-tensile bond emva kokuguga kwe-thermal kwandisa ngokucacileyo.
3. Ngokunyuka komthamo we-cellulose ether, amandla okubambelela kwi-tile yokunamathela emva kokuguga kwe-thermal, kunye namandla okubambelela emva kokungena emanzini kuqala kwaye ayancipha.Isiphumo singcono xa umxholo we-cellulose ether ujikeleze i-0.3%.
Xa usebenzisa i-latex powder edibeneyo, kufuneka sinikele ingqalelo kubungakanani bokusetyenziswa, ukwenzela ukuba ikwazi ukudlala indima yayo ngokwenene.
