I-latex powder enokuchithwa kwakhona
Iputty eludongeni lwangaphakathi nangaphandle, i-tile yokunamathelisa, 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 oluxutywe nodaka oluxubeneyo.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.
Enye: Indima ye-latex powder ehlaziywayo kwi-putty ikakhulu le 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, ifilimu inokuqulunqwa 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.
Ezimbini: Indima ye-latex powder ehlaziywayo kwi-mortar ikakhulu le miba ilandelayo
1. Ukuphucula amandla oxinzelelo kunye namandla okuguquguquka kodaka.
2. Ukongezwa kwe-latex powder kwandisa izinga lokunyusa umdaka, ngaloo ndlela kuphuculwe ukunyanzeliswa kwempembelelo yomdaka, kwaye kuphinde kunikeze umdaka kunye nomphumo omhle wokusabalalisa uxinzelelo.
3. Ukuphucula ukusebenza kwebhondi yodaka.Indlela yokudibanisa isekelwe kwi-adsorption kunye nokusasazwa kwee-macromolecules kwindawo encangathi.Ngelo xesha, i-powder ye-rubber ine-permeability ethile kwaye ingena ngokupheleleyo kwisiseko sezinto ezisisiseko kunye ne-cellulose ether, ukwenzela ukuba iipropati zesiseko kunye ne-plaster entsha zisondele, ngaloo ndlela ukuphucula i-Adsorption kwandisa kakhulu ukusebenza kwayo.
4. Ukunciphisa i-modulus elastic of mortar, ukuphucula amandla okuguqula kunye nokunciphisa i-cracking phenomenon.
5. Ukuphucula ukunyanzeliswa kodaka.Ukuphuculwa kokumelana nokunxiba kubangelwa ikakhulu kubukho beglue ethile ebusweni bodaka.I-powder yeglue isebenza njengebhondi, kwaye isakhiwo se-omentum esakhiwe ngumgubo weglue sinokudlula emigodini kunye nokuqhekeka kwi-samente yodaka.Ukuphucula ukudibanisa phakathi kwezinto ezisisiseko kunye neemveliso ze-samente ze-hydration, ngaloo ndlela kwandisa ukumelana nokunxiba.
6. Nika udaka olubalaseleyo ukuxhathisa kwealkali.
Ezintathu: Indima ye-latex powder ehlaziywayo kwi-adhesives ye-tile ikakhulu le miba ilandelayo
1. Njengoko isixa se-samente sanda, amandla okuqala okunamathela kwi-tile ayanda, kwaye ngelo xesha, amandla okubambelela emva kokucwiliswa emanzini kunye namandla okubambelela emva kokuguga kwe-thermal nawo ayanda.Isixa sesamente kufuneka sibe ngaphezu kwama-35%.
2. Ngokunyuka komthamo womgubo we-latex odityanisiweyo, ukomelela kwebhondi yokuncamathelisa ithayile emva kokuntywiliselwa emanzini kunye nokuqina kokuqina kwebhondi emva kokuguga kobushushu kunyuka ngokufanelekileyo, kodwa ukonyuka kokuqina kokuqina kwebhondi emva kokuguga kobushushu kuphantsi.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%.
Ngoko ke, xa usebenzisa i-latex powder edibeneyo, kufuneka sinikele ingqalelo kwisixa esisetyenzisiweyo, ukuze sikwazi ukudlala indima yayo ngokwenene.
