Indima yei-polymer powder enokuchithwa kwakhonakwiukwakhiwaishishini alinakujongelwa phantsi.Njengezinto ezongezelelweyo ezisetyenziswa ngokubanzi, kunokuthiwa ukubonakala kwepolymer powder edispersible iphucule umgangatho wokwakha ngaphezu kwebanga elinye.Elona candelo liphambili lepolymer powder lidispersible yi-organic macromolecular polymer eneempawu ezizinzileyo.Ngexesha elifanayo, i-PVA yongezwa njenge-colloid ekhuselayo.Ngokuqhelekileyo ngumgubo kwiqondo lokushisa.Isakhono sokuncamathela sinamandla kakhulu kwaye umsebenzi wokwakha nawo ulunge kakhulu.Ukongeza, olu hlobo lwepolymer powder lunokuphucula ngokucacileyo ukunyanzeliswa kokunxiba kunye nokusebenza kwamanzi odongeni ngokuphucula ukudibanisa kodaka.Kwangaxeshanye, ukomelela komanyano kunye nokukhubazeka kukwaqinisekile.iqondo lokuphucula.
I-latex powder enokuchithwa kwakhonailuhlaza, inobubele kokusingqongileyo, ukwakha ukonga amandla, umgubo okumgangatho ophezulu oneenjongo ezininziizinto zokwakha, kwaye luyimfuneko kwaye lubalulekile ukongeza olusebenzayoudaka oluxutywe owomileyo.Inokuphucula ukusebenza kodaka, ukunyusa amandla odaka, ukunyusa amandla okudibanisa phakathi kodaka kunye ne-substrates eyahlukeneyo, ukuphucula ukuguquguquka kunye nokusebenza, amandla oxinzelelo, amandla okuguquguquka, ukuxhathisa ukunxiba, ukuqina, kunye ne-viscosity yodaka.I-Relay kunye nokugcinwa kwamanzi umthamo, ukwakhiwa.Ukusebenza kwe-latex powder enokuphinda ihlakazwe ngaphakathii-tile yokuncamathelisayomelele ngokwentelekiso, kwaye i-latex powder ekwazi ukuphinda ihlakazwe inamandla okudibanisa okuphezulu kunye neempawu ezizodwa.
I-latex powderkuphucula ukuhambelana kunye nokugudiswa kwenkqubo kwimeko yokuxuba okumanzi.Ngenxa yeempawu zepolymer, ukudibanisa kwezinto ezixutywayo ezimanzi kuphuculwe kakhulu, kwaye kunegalelo elikhulu ekusebenzeni;emva kokumisa, inikaukuncamathela Kumaleko agudileyo kunye ashinyeneyo, Phucula ujongano lwesanti, igrabile kunye ne pores.Ngaphantsi kwesiseko sokuqinisekisa inani lokongezwa, kunokutyetyiswa kwifilimu kwi-interface, ukwenzela ukuba i-adhesive tile ine-flexibility ethile, iyanciphisa i-elastic.odulus, kwaye ifunxa uxinzelelo lwe-thermal deformation kubungakanani obukhulu.Kwimeko yokuntywiliselwa kwamanzi kwinqanaba lamva, kuya kubakho uxinzelelo olunjengokumelana namanzi, ubushushu be-buffer, kunye nokuguqulwa kwezinto ezingahambelaniyo (i-tile deformation coefficient 6 × 10-6 / ℃, i-coefficient ye-cement deformation 10 × 10-6 / ℃) , kunye nokuphucula ukuxhathisa imozulu.
Ukongezwa kwepowder ye-latex e-dispersible kwi-adhesives ye-tile kunempembelelo ecacileyo kakhulu ekuphuculeni ukusebenza kwe-samente-based adhesives adhesives, kwaye inefuthe elibalulekileyo kumandla okudibanisa, ukuchasana kwamanzi, kunye nokuguga kokuguga kwe-adhesive.Kukho iintlobo ezininzi zomgubo welatex odispersible kwakhona wokuncamatheliswa kwethayile kwimarike, njenge-acrylic redispersible latex powder, styrene-acrylic powder, vinyl acetate-ethylene copolymer, njl. .Uninzi lwe-latex powder oluchithwayo luyii-vinyl acetate-ethylene copolymer.
(1) Njengoko isixa sesamente sisanda, amandla okuqala omgubo we-latex odispersible wokuncamathelisa ithayile ayanda, kwaye kwangaxeshanye, ukomelela okuncamathelayo okuqinileyo emva kokuntywiliselwa emanzini kunye nokomelela okuncamathelayo emva kokuguga kobushushu nako kuyanda.
2 , ukuqina kokuqina kwebhondi kwanda kakhulu.
Indlela yendabuko yokuncamathisela yeethayile yindlela yokwakha engqingqwa, oko kukuthi, okokuqala sebenzisa udaka oluqhelekileyo ngasemva kweethayile, kwaye emva koko ucinezele iithayile kwinqanaba lesiseko.Ubunzima bomgangatho wodaka malunga ne-10 ukuya kwi-30mm.Nangona le ndlela ifaneleke kakhulu ukwakhiwa kwiziseko ezingalinganiyo, izinto ezingeloncedo zisebenza kakuhleukubeka iithayile, iimfuneko eziphezulu zobuchule bobugcisa babasebenzi, ingozi eyongezelelekileyo yokuwa ngenxa yokungabi bhetyebhetye kodaka, nobunzima bokulungisa udaka kwindawo yokwakha.Umgangatho ulawulwa ngokungqongqo.Le ndlela ifanelekile kuphela kwiithayile ezinezinga eliphezulu lokufunxa amanzi.Ngaphambi kokuncamathisela iithayile, iithayile kufuneka zifakwe emanzini ukuze zifumane amandla okwaneleyo.
