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 elilandelayo, kuya kubakho uxinzelelo olufana nokumelana 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. 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, usetyenziso lwabo lubanzi kakhulu. Indima ye-hydroxypropyl methylcellulose idlala indima yokugcinwa kwamanzi, ukuqina kunye nokusebenza kokwakhiwa kwinqanaba lokuqala, kwaye i-latex powder edibeneyo ye-adhesive ye-tile idlala indima yamandla kwinqanaba elilandelayo, elidlala indima enhle kakhulu ekuqineni, i-asidi. kunye nokumelana ne-alkali yeprojekthi. Impembelelo ye-tile enamathelayo edibeneyo yomgubo we-latex kudaka olutsha: ukwandisa ixesha lokusebenza kwaye ulungelelanise ixesha lokuphucula ukusebenza kokugcinwa kwamanzi, ukwenzela ukuba kuqinisekiswe ukuhanjiswa kwesamente kunye nokuphucula ukuxhathisa kwe-sag (i-powder yerabha elungisiweyo ekhethekileyo) kunye nokuphucula ukusebenza (kulula ukusebenzisa i-Substrate kulwakhiwo oluphezulu, kulula ukucinezela iithayile kwi-adhesive) indima yodaka oluqinileyo inokunamathela okuhle kwii-substrates ezahlukeneyo, kubandakanya ikhonkrithi, 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 wokuncamathisela ithayile kwimarike, ezifana acrylic redispersible latex powders, styrene-acrylic powders, vinyl acetate-ethylene copolymers, njl. Uninzi lwamathambo e-latex anokuphinda ahlakazwe zi-vinyl acetate-ethylene copolymers.
(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.
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, umngcipheko owongezelelekileyo wokuwa ngenxa yokungaguquguquki kakuhle kodaka, kunye 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 yokufaka ithayile esetyenziswa kakhulu eYurophu yinto ebizwa ngokuba yindlela yokuncamathela ebhityileyo, oko kukuthi, ibhetshi yokuncamathelisa yethayile eyenziwe ngepolymer-modified ikhutshiwe kumphezulu womaleko wesiseko ukuze ifakwe iithayile kwangaphambili nge-spatula enamazinyo. yenza 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 se-tile sinentsebenzo efanelekileyo yokudibanisa kwiintlobo ezahlukeneyo zeeleyile zesiseko kunye neengqimba zomphezulu ezibandakanya iithayile ze-vitrified kunye nokufunxwa kwamanzi aphantsi kakhulu, kwaye inokuguquguquka okuhle, ukuze ifunxe. Uxinzelelo olubangelwa zizinto ezinjengomahluko weqondo lobushushu, kunye nokuxhathisa okugqwesileyo kwe-sag, ixesha elide elaneleyo lokuvula ulwakhiwo olucekethekileyo, olunokukhawulezisa kakhulu isantya sokwakha, kulula ukusebenza kwaye akukho mfuneko yokumanzisa iithayile kwangaphambili emanzini. Le ndlela yokwakha ilula ukusebenza kwaye kulula ukuyiqhuba ulawulo lomgangatho wolwakhiwo kwisiza.
