Le mveliso i-adhesive-soluble adhesive, eyi-adhesive thermoplastic adhesive elungiselelwe yi-polymerization ye-vinyl acetate monomer phantsi kwesenzo somqalisi.Ngokuqhelekileyo ibizwa ngokuba yi-latex emhlophe okanye i-emulsion ye-PVAC ngokufutshane.Igama layo lekhemikhali yi-polyvinyl acetate adhesive.Yenziwe nge-acetic acid kunye ne-ethylene ukudibanisa i-vinyl acetate kunye ne-titanium dioxide eyongeziweyo (amabanga aphantsi ongezwa nge-calcium ekhanyayo, i-talc, kunye nezinye iipowders).Emva koko zifakwe i-polymerized nge-emulsion.Njengolwelo olutyebileyo olunobisi olumhlophe.
Ukomisa ngokukhawuleza, ukunyathela okulungileyo kokuqala, ukusebenza kakuhle;ukunamathela olomeleleyo, ukomelela okuphezulu koxinzelelo;ukumelana nobushushu obunamandla.
ukusebenza
1Ingasetyenziselwa ngokubanzi ukudibanisa iimveliso zephepha (i-wallpaper), kwaye ingasetyenziselwa njengento yokubambelela kwiingubo ezingenamanzi kunye neenkuni.
(2) Isebenzisa amanzi njengesixhobo sokuchitha amanzi, ikhuselekile ukusebenzisa, ayinatyhefu, ayinakutsha, kulula ukuyicoca, iyaqina kwiqondo lobushushu begumbi, incamathele kakuhle emthini, ephepheni nakwilaphu, inamandla okubopha okuphezulu, kwaye iyanyangeka. umaleko oncamathelayo awunambala ocacileyo, ukuqina okulungileyo, awungcolisi into ebotshiweyo.
(3) Inokusetyenziswa kwakhona njenge-modifier ye-phenolic resin, i-urea-formaldehyde resin kunye nezinye izinto zokunamathela, kwaye isetyenziselwa ukwenza ipeyinti ye-latex ye-polyvinyl acetate.
(4) I-emulsion inozinzo oluhle, kwaye ixesha lokugcina linokufikelela ngaphezu kwesiqingatha sonyaka.Ke ngoko, inokusetyenziswa ngokubanzi ekushicileleni nasekubopheni, ukwenziwa kwefenitshala, kunye nokudityaniswa kwephepha, umthi, ilaphu, ufele, iiseramikhi, njl.
Iimbonakalo
1. Inokubambelela ngokuqinileyo kwizinto ezinqabileyo ezifana nemithi, iphepha, ikotoni, isikhumba, iiseramics, njl., kunye ne-viscosity yokuqala iphezulu kakhulu.
2. Inokunyangwa kwiqondo lokushisa, kwaye isantya sokunyanga sikhawuleza.
3. Ifilimu icacile, ayingcolisi ukunamathela, kwaye kulula ukuyiqhuba.
4. Ukusebenzisa amanzi njengomthombo wokusasazwa, akatshi, akanagesi eyityhefu, akangcolisi indalo, kwaye akhuselekile kwaye alungcolisi.
5. Yinto enye ye-viscous liquid, ekulungele ngakumbi ukuyisebenzisa.
6. Ifilimu ephilisiweyo inomlinganiselo othile wokuqina, ukuxhathisa ukuxutywa kwe-alkali, i-asidi ye-dilute, kunye nokumelana neoli.
Isetyenziswa kakhulu ekusetyenzweni komthi, ukudibanisa ifanitshala, imilomo yecuba, ukuhombisa ulwakhiwo, ukudityaniswa kwelaphu, ukusetyenzwa kwemveliso, ukuprinta kunye nokubophelela, ukwenziwa kwezandla, ukwenziwa kwesikhumba, ukulungisa iilebhile, ukuncamathelisa iithayile, njl.
amandla
I-latex emhlophe ehambelana nokusingqongileyo kufuneka kuqala ibe namandla okwaneleyo okudibanisa, ukwenzela ukuba kuqinisekiswe ukuba umgangatho weemveliso zephepha awuyi kuchaphazeleka emva kokudibanisa.
Ukugweba ukuba amandla okudityaniswa kwe-latex emhlophe ehambelana nokusingqongileyo afanelekile, iziqwenga ezibini zemathiriyeli encamatheleyo zinokukrazulwa ecaleni kojongano oludityanisiweyo.Ukuba izinto ezidibeneyo zifunyenwe zonakaliswe emva kokukrazula, amandla okubambisana anele;ukuba kuphela ujongano oludityanisiweyo lwahluliwe, Ibonisa ukuba amandla e-latex emhlophe ehambelana nokusingqongileyo ayonelanga.Ngamanye amaxesha i-latex emhlophe ehambelana nokusingqongileyo kunye nokusebenza kakubi kuya kuchithwa kwaye ifilimu iya kuba brittle emva kokugcinwa ixesha elithile kwiqondo lokushisa eliphezulu okanye kwindawo yokushisa ephantsi.Ngoko ke, kuyimfuneko ukwenza utshintsho oluphezulu lwe-thermal kunye neembrittlement zokuvavanya ubushushu obuphantsi ukufumanisa ukuba umgangatho walo uthembekile.
