I-Latex powder-Phucula ukuhambelana kunye nokutyibilika kwenkqubo kwimeko yokuxuba okumanzi. Ngenxa yeempawu zepolymer, ukudibanisa kwezinto ezixutywayo ezimanzi ziphuculwe kakhulu, ezincedisa kakhulu ekusebenzeni; emva kokumisa, inika ukunamathela kwinqanaba eligudileyo nelixineneyo. Relay, phucula isiphumo sojongano lwesanti, igrabile, kunye neepores. Ngaphantsi kwesiseko sokuqinisekisa inani lokongezwa, kunokutyetyiswa kwifilimu kwi-interface, ukwenzela ukuba i-adhesive tile ine-flexibility ethile, iyanciphisa i-modulus elastic, kwaye ithathe uxinzelelo lwe-thermal deformation kumlinganiselo omkhulu. 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-samente yokuguqula i-concrete 10 × 10-6 / ℃), kunye nokuphucula ukumelana nemozulu. IHydroxypropyl Methyl Cellulose HPMC-Nikeza ugcino lwamanzi olulungileyo kunye nokusebenza kakuhle kodaka olutsha, ngakumbi kwindawo emanzi. Ukuze kuqinisekiswe inkqubela phambili egudileyo ye-hydration reaction, inokuthintela i-substrate kwi-absorption eninzi yamanzi kunye nomgangatho womhlaba ukuba uphume. Ngenxa yepropati yayo yokungenisa umoya (1900g/L—-1400g/LPO400 isanti 600HPMC2), ubuninzi be-adhesive tile adhesive iyancitshiswa, izinto ezigcinayo kunye nokunciphisa imodyuli elastiki yodaka oluqinileyo.
I-Tile adhesive redispersible latex powder iluhlaza, ihambelana nokusingqongileyo, ukwakha ukonga umbane, umgangatho ophezulu wezinto ezininzi zokwakha umgubo wezinto ezininzi, kwaye uyimfuneko ebalulekileyo kunye neyongezelelweyo esebenzayo yodaka oluxubeneyo. 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-tile ye-adhesive redispersible latex powder yomelele, kwaye i-tile yokunamathela i-latex powder inamandla okudibanisa kunye neempawu ezizodwa. Ke ngoko, uluhlu lwabo lokusetyenziswa lubanzi kakhulu. Indima ye-hydroxypropyl methylcellulose idlala indima yokugcinwa kwamanzi, ukuqina kunye nokusebenza kokwakhiwa kwinqanaba lokuqala, kwaye i-latex powder edibeneyo edibeneyo ye-tile idlala indima yamandla kwinqanaba elilandelayo, elidlala indima enhle kakhulu ekuqineni, i-asidi kunye nokumelana ne-alkali yeprojekthi. Impembelelo ye-tile encamathelayo iphinda iphinde iphinde iphinde ibe ngumgubo welatex kudaka olutsha: ukwandisa ixesha lokusebenza kwaye ulungelelanise ixesha lokuphucula ukusebenza kokugcinwa kwamanzi, ukuze kuqinisekiswe i-hydration yesamente kunye nokuphucula ukuxhathisa kwe-sag (umgubo okhethekileyo werabha eguquliweyo) kunye nokuphucula ukusebenza (kulula ukusebenzisa i-Substrate kulwakhiwo oluphezulu, kulula ukucinezela iithayile kwi-adhestration, indima encamathelayo, i-concrete encamathelayo, indima encamathelayo kwi-adhestration) i-plaster, umthi, iithayile ezindala, i-PVC naphantsi kweemeko zemozulu ezahlukeneyo, inamandla okuguqula kakuhle.
Ukongezwa kwepowder ye-latex edibeneyo ye-adhesives ye-tile inempembelelo ecacileyo kakhulu ekuphuculeni ukusebenza kwe-samente-based adhesives tile, kwaye inefuthe elibalulekileyo kumandla okudibanisa, ukuxhathisa kwamanzi, kunye nokuguga kokuguga kwe-adhesive. Okwangoku, kukho iintlobo ezininzi zomgubo welatex odispersible wokuncamatheliswa kwethayile kwimarike, njenge-acrylic redispersible latex powders, styrene-acrylic powders, vinyl acetate-ethylene copolymers, njl. Ngokuqhelekileyo, izinto zokuncamathelisa iithayile ezisetyenziswa kwizincamathelisi zethayile kwimarike Uninzi lwe-adhesivesible aceaceace.
(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.

Ngenxa yeempawu zayo ezintle zokuhombisa kunye nokusebenza njengokuqina, ukumelana kwamanzi kunye nokucocwa lula, iithayile ze-ceramic zisetyenziswa ngokubanzi: kubandakanywa iindonga, imigangatho, iisilingi kunye namachibi okubhukuda, njl., kwaye ingasetyenziselwa ngaphakathi nangaphandle. 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 kulwakhiwo kwiziseko ezingalinganiyo, izinto ezingeloncedo kukusebenza okuphantsi kweethayile zokufaka iithayile, iimfuno eziphakamileyo zobuchule bobugcisa babasebenzi, ukwanda komngcipheko wokuwa ngenxa yokungaguquguquki kakuhle 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.
Okwangoku, indlela yokufakwa kwethayili esetyenziswa kakhulu eYurophu yinto ebizwa ngokuba yi-thin-layer sticking method, oko kukuthi, i-batch ye-adhesive ye-polymer-modified tile ikhutshiwe kumphezulu womgangatho wesiseko ukuze ufakwe iithayile kwangaphambili nge-spatula enamazinyo ukwenza imivimbo ephakanyisiweyo. Kwaye umaleko wodaka wobunzima obufanayo, uze ucinezele iileyile kuyo kwaye ujike kancinci, ubukhulu bomgangatho wodaka malunga ne-2 ukuya kwi-4mm. Ngenxa yokuguqulwa kwe-cellulose ether kunye ne-latex powder edispersible, ukusetyenziswa kwesi sincamathelisi sethayile sinentsebenzo efanelekileyo yokudibanisa kwiintlobo ezahlukeneyo zemigangatho yesiseko kunye neengqimba zomphezulu ezibandakanya iithayile ze-vitrified kunye nokufunxwa kwamanzi aphantsi kakhulu, kwaye inobubhetyebhetye obuhle, ukuze ifunxe uxinzelelo olubangelwa yimiba enjengomahluko wobushushu, kunye nokugqwesa okugqwesileyo kwe-sag ukumelana, ukwakhiwa kwesantya esincinci, ixesha elide elaneleyo lokuvula kunye nesantya esincinci sokuvula, ukwakhiwa kwesantya esincinci, ixesha elide elaneleyo lokuvula kunye nesantya esincinci. akukho mfuneko yokumanzisa iithayile kwangaphambili emanzini. Le ndlela yokwakha ilula ukusebenza kwaye kulula ukuyiqhuba ulawulo lomgangatho wolwakhiwo kwisiza.
