I-Latex powder—Thuthukisa ukuvumelana nokushelela kwesistimu esimweni sokuhlangana esimanzi. Ngenxa yezici ze-polymer, ukuhlangana kwezinto ezixubene ezimanzi kuthuthukiswa kakhulu, okufaka isandla kakhulu ekusebenzeni; ngemva kokumisa, inikeza ukunamathela kungqimba olubushelelezi noluminyene. Edlulisa, uthuthukise umphumela wesihlabathi, amatshe, nezimbotshana. Ngaphansi kwesisekelo sokuqinisekisa inani lokwengeza, lingathuthukiswa libe yifilimu esibonakalayo, ukuze i-adhesive tile ibe nokuguquguquka okuthile, inciphise i-elastic modulus, futhi ibambe ukucindezeleka kokushisa okushisayo ngezinga elikhulu. Esimeni sokucwiliswa kwamanzi esigabeni sakamuva, kuzoba nezingcindezi ezinjengokumelana namanzi, izinga lokushisa le-buffer, kanye nokuguqulwa kwezinto ezingahambisani (i-tile deformation coefficient 6×10-6/℃, i-coefficient yokuguga kukasimende 10×10-6/℃) , futhi uthuthukise ukumelana nesimo sezulu. IHydroxypropyl Methyl Cellulose HPMC—Nikeza ukugcinwa kwamanzi okuhle nokusebenza kahle kodaka olusha, ikakhulukazi endaweni emanzi. Ukuze kuqinisekiswe ukuqhubeka kahle kokusabela kwe-hydration, kungavimbela i-substrate ekumunceni amanzi ngokweqile kanye nongqimba lwangaphezulu ekuhwamukeni. Ngenxa yendawo yayo yokungenisa umoya (1900g/L—-1400g/LPO400 sand 600HPMC2), ukuminyana kwenqwaba ye-adhesive tile kuyancishiswa, okonga izinto futhi kunciphisa imodulus enwebekayo yodaka oluqinile.
Impushana ye-latex enamathelayo enamathelayo iwuhlaza, ivumelana nemvelo, igcina amandla, isezingeni eliphezulu, iyisithako esibalulekile nesibalulekile esisebenzayo sodaka oluxutshwe okomile. Ingathuthukisa ukusebenza kodaka, yandise amandla odaka, yandise amandla okubopha phakathi kodaka nama-substrates ahlukahlukene, ithuthukise ukuguquguquka nokusebenza, amandla acindezelayo, amandla okuguquguquka, ukumelana nokugqoka, ukuqina, kanye ne-viscosity yodaka. Umthamo wokudlulisa kanye nokugcinwa kwamanzi, ukwakheka. Ukusebenza kwe-adhesive ye-latex powder enamathelayo ephindwe kabili kunamandla kakhulu, futhi i-latex enamathelayo enamathelayo ephinde ihlakazeke i-latex powder inekhono eliphezulu lokubopha kanye nezakhiwo ezihlukile. Ngakho-ke, ububanzi bokusetshenziswa kwabo bukhulu kakhulu. Indima ye-hydroxypropyl methylcellulose idlala indima yokugcina amanzi, ukuqina nokusebenza kokwakhiwa ekuqaleni, futhi i-latex powder enamathelayo ye-tile idlala indima yamandla esigabeni sakamuva, esidlala indima enhle kakhulu ekuqineni, i-asidi. kanye nokumelana ne-alkali kwephrojekthi. Umphumela we-adhesive adhesive redispersible latex powder odakeni olusha: ukwandisa isikhathi sokusebenza futhi ulungise isikhathi sokuthuthukisa ukusebenza kokugcinwa kwamanzi, ukuze kuqinisekiswe ukugeleza kukasimende futhi kuthuthukise ukumelana ne-sag (impushana yerabha eguquliwe ekhethekile) futhi kuthuthukiswe ukusebenza (okulula ukusebenzisa i-Substrate ukwakhiwa okuphezulu, kulula ukucindezela amathayili ku-adhesive) indima yodaka oluqinile inokunamathela okuhle kuma-substrates ahlukahlukene, kufaka phakathi ukhonkolo, i-plaster, izinkuni, amathayili amadala, i-PVC ngisho nangaphansi kwezimo ezihlukahlukene zezulu , inekhono elihle lokuguquguquka.
Ukwengezwa kwempushana ye-latex ehlakazeka kabusha yezinamatheliso zamathayili kunomphumela osobala kakhulu ekuthuthukisweni kokusebenza kwezinamathelisi ezisekelwe kusimende, futhi kunomthelela omkhulu emandleni okubopha, ukumelana namanzi, nokumelana nokuguga kwe-adhesive. Njengamanje, kunezinhlobo eziningi zezimpushana ze-latex ezihlakazeka kabusha zokunamathisela amathayela emakethe, njengezimpushana ze-acrylic redispersible latex, izimpushana ze-styrene-acrylic, ama-vinyl acetate-ethylene copolymers, njll. Ngokuvamile, izinto zokunamathisela zamathayela ezisetshenziswa emakethe yokunamathela Izimpushana eziningi ze-latex ezihlakazeka kabusha ziyi-vinyl acetate-ethylene copolymers.
(1) Njengoba inani likasimende likhula, amandla okuqala empushana ye-latex ehlakazeka kabusha yokunamathisela ithayela ayanda, futhi ngesikhathi esifanayo, amandla okunamathela aqinile ngemva kokucwiliswa emanzini kanye namandla okunamathela aqinile ngemva kokuguga kokushisa nawo ayanda.
(2) Ngokukhula kwenani lempushana ye-latex ehlakazeka kabusha yokunamathela kuthayela, amandla ebhondi eqinile yempushana ye-latex ehlakazeka kabusha yokunamathela kuthayela ngemva kokucwiliswa emanzini kanye namandla esibopho esiqinile ngemva kokuguga kokushisa anda ngokufanele, kodwa ukuguga okushisayo Ngemva kwalokho. , amandla esibopho esiqinile anda kakhulu.
Ngenxa yezici zayo ezinhle zokuhlobisa nokusebenza njengokuqina, ukumelana kwamanzi nokuhlanza kalula, amathayili e-ceramic asetshenziswa kabanzi: kufaka phakathi izindonga, phansi, uphahla kanye namachibi okubhukuda, njll, futhi angasetshenziswa kokubili ngaphakathi nangaphandle. Indlela yendabuko yokunamathisela yama-tile iyindlela yokwakha ungqimba olujiyile, okungukuthi, qala ngokufaka udaka olujwayelekile ngemuva kwama-tile, bese ucindezela amathayili kungqimba oluyisisekelo. Ubukhulu bengqimba yodaka cishe buyi-10 kuya ku-30mm. Nakuba le ndlela ifaneleka kakhulu ukwakhiwa ezisekelweni ezingalingani, ububi ukusebenza kahle okuphansi kothayela, izidingo eziphakeme zobuchwepheshe babasebenzi, ingozi eyengeziwe yokuwa ngenxa yokungaguquguquki kahle kodaka, nobunzima bokulungisa udaka endaweni yokwakha. . Ikhwalithi ilawulwa ngokuqinile. Le ndlela ifaneleka kuphela kumathayili anezinga eliphezulu lokumuncwa kwamanzi. Ngaphambi kokunamathisela amathayili, amathayili adinga ukucwiliswa emanzini ukuze athole amandla ebhondi anele.
Njengamanje, indlela yokufakwa kwamathayela esetshenziswa kabanzi e-Europe yindlela ebizwa ngokuthi indlela yokunamathelisa ungqimba oluncane, okungukuthi, i-polymer-modified tile adhesive batch iklwetshwa phezu kongqimba oluyisisekelo ukuze lufakwe amathayela kusenesikhathi nge-spatula enamazinyo. yakha imivimbo ephakanyisiwe. Futhi ungqimba lodaka lobukhulu obufanayo, bese ucindezela amathayili kuso bese usonta kancane, ubukhulu bongqimba lodaka cishe 2 kuya ku-4mm. Ngenxa yokuguqulwa kwe-cellulose ether kanye nempushana ye-latex ehlakazeka kabusha, ukusetshenziswa kwalesi sinamathiselo sethayela sinokusebenza okuhle kokubopha ezinhlotsheni ezihlukene zezendlalelo zesisekelo nesendlalelo esingaphezulu okuhlanganisa amathayela ane-vitrified ngokugcwele nokumuncwa kwamanzi aphansi kakhulu, futhi kunokuguquguquka Okuhle, ukuze amunce. ukucindezeleka okubangelwa izici ezifana nomehluko wokushisa, nokumelana okuhle kakhulu kwe-sag, isikhathi eside esanele sokuvula ukwakhiwa kongqimba oluncane, okungasheshisa kakhulu isivinini sokwakha, kulula ukusebenza futhi asikho isidingo sokumanzisa amathayili emanzini. Le ndlela yokwakha kulula ukuyisebenzisa futhi kulula ukwenza ukulawula izinga lokwakhiwa kwendawo.
