Emkhakheni wokuhlobisa izakhiwo, itshe lemvelo lithandwa ngenxa yobuhle balo obuyingqayizivele nokuqina. Amaphutha emvelo e-Stone, okuhlanganisa izimbotshana nemifantu, nokho anciphisa ukusetshenziswa kwawo okubanzi nokuphepha. Ngakho-ke, ubuchwepheshe bokuhlanganiswa kwesakhiwo buye baba yindlela eyinhloko yokwandisa ukuphepha nokusebenza kahle kokusetshenziswa kwamatshe. Isidingo sokuhlangana kwesakhiwo setshe lemvelo sizoxoxwa ngalo kulesi sihloko kanye nokusetshenziswa kanye nezinzuzo i-epoxy resin ama-adhesive emhlobiso wamatshe. Sizohlola izakhiwo, ukusetshenziswa kanye nokuguqulwa kwe-epoxy resin etsheni elomile elilengayo futhi sibheke phambili ekuthuthukisweni kwayo kwesikhathi esizayo ekuhlobiseni kwezakhiwo. Ukwazi ngokujulile lokhu okuqukethwe kuzosisiza ukuthi sisebenzise kangcono izinto ezinamathelayo ze-epoxy resin ukuze sinikeze umkhakha wokwakha izixazululo zokuhlobisa amatshe ezinhle kakhulu, eziphephile, ezinobungani bemvelo.
Isidingo sokuhlangana kwesakhiwo kwetshe lemvelo
Umphumela wobuhle wetshe lemvelo utuswa kakhulu, ngenxa yokuthungwa kwawo okulula futhi okungokwemvelo nombala, unikeza umhlobiso wezakhiwo isimo sengqondo esihle nesiyingqayizivele. Amandla anciphile etshe lemvelo aphumela emaphutheni alo avamile, noma kunjalo, okuhlanganisa izimbotshana, imifantu, imigodi, njll. Ukuhlangana kwesakhiwo sekubaluleke kakhulu ukuze kuqinisekiswe ukusetshenziswa okugcwele kwetshe. Ubuchwepheshe bokuhlanganiswa kwesakhiwo abenzi nje kuphela ukukhubazeka kwetshe, kodwa futhi kuxazulula izinkinga ezifana nokunamathela okwanele okungase kubangelwa ukusetshenziswa kodaka lukasimende, ukuze lelo tshe linamathele ngokuqinile kuma-substrates afana namafreyimu ensimbi. Ngaphezu kwalokho okuzuzisayo ekusetshenzisweni komhlobiso wodonga lwamatshe kuwukuhlangana kwesakhiwo, ikakhulukazi ekwakhiweni kwe-facade nezindonga zamakhethini. Ithuthukisa ubuqotho nokubukeka kwesakhiwo futhi isiza nobuchwepheshe bokwakha ukuthi buthuthuke.
Ukusetshenziswa kwe-epoxy resin adhesive ekuhlanganisweni kwesakhiwo kwetshe
I-epoxy resin adhesive isetshenziswa kakhulu ekuhlobiseni amatshe nasekulungiseni ngenxa yokusebenza kwayo okuhle kakhulu kokubopha. Isakhiwo samangqamuzana e-epoxy resin sihlanganisa amaqembu amaningi, kuhlanganise namaqembu e-epoxy nama-hydroxyl, asinika amandla amakhulu okunamathela kanye nekhono lokuzivumelanisa nezinto ezibonakalayo. Izinga le-epoxy resin's colloid shrinkage liphansi ngemuva kokwengeza i-ejenti yokwelapha, ngaleyo ndlela ingakwazi ukugcina ukuqina, ukumelana nesimo sezulu, nokuzinza. Ngaphezu kwalokho, i-epoxy resin ayikhiqizi imikhiqizo ethile ngesikhathi sokwelashwa, ngakho-ke ivimbela ukungcoliswa kwamatshe okwesibili. Ngakho-ke, kufanelekile ukwakha ezindaweni eziningana, okuhlanganisa ngaphandle, ngaphakathi, nokunye ukusetshenziswa okuhlukile.
Izinzuzo ze-epoxy resin adhesive
1. Amandla okubopha okuhle kakhulu: amaqembu e-epoxy, amaqembu e-hydroxyl namanye amaqembu angakha amandla aqinile e-intermolecular ngezinto ezifana namatshe nensimbi;
2. Ukuncipha okuncane: I-shrinkage ye-colloid ngesikhathi senqubo yokuphulukisa i-2% ~ 3% kuphela, futhi isigcwalisi singancishiswa ngokuqhubekayo;
3.Ukuzinza kwe-Dimensional: Isakhiwo sizinzile ngemva kokubopha, ukubukeka kuhlanzekile, futhi akulula ukukhubazeka;
4.Ukumelana nesimo sezulu: Ingakwazi ukumelana namandla emvelo anjengomoya, ukuzamazama komhlaba, nokushintsha kwezinga lokushisa;
5.Ukuzivumelanisa nezimo okuqinile: Ifanele ukwakhiwa ezindaweni ezahlukene ngaphandle kwezimo eziqinile zokushisa;
6.Ngaphandle kokungcola: Azikho izincibilikisi eziyingozi ezihwamukayo phakathi nenqubo yokwelapha noma noma yikuphi ukungcola okukhiqizwa etsheni;
7.Isetshenziswa kakhulu: Imikhiqizo ngamafomu amaningana ingadalwa ngokusekelwe ezidingweni zamatshe.
Ukungalungi kwe-epoxy resin adhesive
1.Ukuqina okuphezulu: I-epoxy resin engashintshiwe ixetshulwa kalula ngemva kokuqina;
2.Isikhathi sokwakha esifushane: I-epoxy resin adhesives idinga ukugcwaliswa phakathi nesikhathi esithile, esingahambisani namaphrojekthi ayinkimbinkimbi;
3. Ukukhathazeka ngokuphepha: Eminye imikhiqizo ye-epoxy resin ingase ikhiqize ukuguquguquka; ngakho-ke, umuntu kufanele anake ngokukhethekile ukuvikelwa kokuphepha.
Indima ye-epoxy resin adhesive etsheni elomile elilengayo
Kusukela i i-epoxy resin adhesive yalungiswa ngempumelelo okokuqala eJalimane Chemical Industry Company ngo-1934, kancane kancane iye yasetshenziswa kabanzi emkhakheni wokwakha. Ekuqaleni igxile ekwakhiweni kodaka lukasimende olumanzi, indlela yokumanzisa iphumela kalula “ekushintsheni kwe-pathological” etsheni, ngaleyo ndlela yaguqukela endleleni eyomile yokulenga. Okuqinile futhi okuhlala isikhathi eside, i-epoxy resin adhesive esetshenziswa endleleni eyomile yokulenga ingenza itshe lizimele odakeni lukasimende, lehlise kakhulu izinkinga zokuba mhlophe nokuwa okubangelwa udaka lukasimende. Okulandelayo kuhlukanisa inqubo yokulenga okomile:
1.Ikhwalithi ephezulu yokufaka: Indlela yokulenga eyomile isebenzisa izingxenye zensimbi ukusekela nokwenza isakhiwo esiqinile;
2.Isivinini sokwakha esisheshayo: Indlela yokulenga eyomile ayidingi udaka lukasimende futhi ingaqedela ngokushesha ukubeka nokuhlanganisa;
3.Umfutho womoya onamandla nokumelana nokuzamazama komhlaba: Ezakhiweni eziphakeme kakhulu, isakhiwo sendlela yokulenga esomile ngeke siwe ngenxa yokudlidliza kwesakhiwo noma ukucindezela komoya;
4.Ukulungisa okulula: Indlela yokulenga eyomile i-modularized, elungele ukugcinwa nokushintshwa kamuva.
Ukwakhiwa nokuguqulwa kwe-epoxy resin adhesives
Ama-adhesive e-epoxy resin ngokuvamile akhiwa i-epoxy resin kanye ne-ejenti yokwelapha. Ama-Diluent, ama-filler, ama-ejenti aqinisayo, njll. nawo afakiwe ukuze kuthuthukiswe ukusebenza futhi kwakhiwe okunamathelayo okuguquliwe kwe-epoxy resin ukuze kwandiswe ukusebenza kwazo. Phakathi kwezilungisi ezisetshenziswa kaningi kukhona ama-ejenti ahlanganisayo e-silane, ama-toughening agents, njll. Ngalawa masu okulungisa, ukuguquguquka nokuqina kwe-colloid kungathuthukiswa ngokwanele ukuze kwanelise izidingo ezengeziwe zokuhlobisa amatshe. Ikakhulukazi ezinhlelweni ezifana nezindonga zangaphandle nezindonga zamakhethini, okunamathiselwe kwe-epoxy resin eguquliwe kunikeza ukusebenza okuhle ekuhlobiseni kwamatshe futhi kunganikeza ukwesekwa okuthembekile kwesikhathi eside.
Ukuthuthukiswa okuzayo kwe-epoxy resin adhesives emhlobiso wezakhiwo
Ama-adhesive e-epoxy resin azonaka kakhulu intuthuko elandelayo yesikhathi esizayo embonini yokuhlobisa izakhiwo ngokusebenza kahle kokwakhiwa, ikhwalithi yokuhlobisa nokusebenza kokuvikela imvelo:
1.Ukuvikelwa kwemvelo: ukusika ukusetshenziswa kwamakhemikhali ayingozi futhi kukhuphule ukusebenza kokunamathela kwe-epoxy ekuvikeleni indawo ezungezile;
2.Ukuvumelana nezimo: ngcono nakakhulu ukuguquguquka kanye nokunciphisa ukuqina ngokulungiswa nokuguqulwa kwesakhiwo samangqamuzana;
3.Ukwakha kube lula: thuthukisa imikhiqizo ye-epoxy resin okulula ukuyisebenzisa nokwenza lula inqubo yokwakha;
4.Ukumelana nesimo sezulu okuthuthukisiwe: sabela ezinhlobonhlobo zokuguquguquka kwesimo sezulu futhi uthuthukise ukumelana nesimo sezulu sesikhathi eside sezinto ezinamathelayo ze-epoxy.
Ukuhlangana kwesakhiwo kwetshe kuncike kakhulu ekunamatheleni kwe-epoxy resin. Ukusebenza kwayo okuhle kakhulu kokubopha kanye nokuvumelana nezimo kuye kwakhuthaza ukuthuthukiswa kobuchwepheshe bokulenga amatshe okomile, kuyilapho kuthuthukisa ubuhle nokusebenza kahle kokwakhiwa kwezakhiwo. Isayensi yezinto ezibonakalayo izovula amathuba amaningi okufaka isicelo sokunamathisela i-epoxy resin emhlobiso wamatshe, ngakho-ke ukuhlinzeka ngezixazululo eziningi ze-premium bonding zomkhakha wokwakha.
