Ixesha lokugcina
1. Imveliso nganye inexesha lokugcina. Ngokwemigangatho yamazwe ngamazwe kunye nekhaya, ixesha lokugcina libhekisela kwixesha lokugcinwa kwiqondo lokushisa (24 ° C). Kwizinto zokuncamathelisa ze-acrylic, yi-20°C.
2. Kwiimveliso ze-acrylic, iqondo lokushisa eliphezulu, lifutshane ixesha lokugcina.
3. Kwimveliso ezisekelwe emanzini, ukuba iqondo lobushushu lingaphantsi -1°C, liya kuchaphazela ngqo umgangatho wemveliso.
Amandla
- 1. Kungcono ukhethe ii-adhesives ezikhethekileyo kwii-adherends ezahlukeneyo.
- 2. Ukuqina kufuneka kuthathelwe ingqalelo ngaphezu kokuqina kokubambisana kokuqala.
- 3. Ukusebenza kokuncamatheliswa kokunyanga ubushushu kuphezulu kakhulu kunoko kwegumbi-iingcina zokunyanga ubushushu. Ukuba kufuneka amandla aphezulu kunye nokuqina okuhle, kufuneka kukhethwe izinto ezincamathelayo zokunyanga ubushushu obuphezulu.
- 4. Iglue ye-Cyanoacrylate (i-502 super glue) ayifanele isetyenziswe kwizinto ezifuna amandla aphezulu okubambisana ngaphandle kokulungiswa kwendawo engxamisekileyo okanye encinci kunye nemveliso eqhubekayo.
Abanye
- 1. I-latex emhlophe kunye ne-urea-formaldehyde glue ayinakusetyenziselwa ukubopha isinyithi.
- 2. Ukuba i-adhesive ebonakalayo iyadingeka, i-polyurethane adhesive, i-optical epoxy adhesive, i-adhesive polyester egcweleyo, kunye ne-adhesive acetal ye-polyvinyl ingasetyenziswa.
- 3. I-adhesive ayifanele ibe yi-corrosive kwi-adherend. Umzekelo, i-solvent-esekelwe kwi-chloroprene adhesive ayinakusetyenziswa kwiibhodi ze-polystyrene foam.
- 4. I-Adhesives ene-brittleness ephezulu ayifanelekanga ukunamathela izinto ezithambileyo.
Izilumkiso xa usebenzisa iglue ye-AB
- 1. Ukunamathela kwecandelo le-AB, nceda udibanise ngokweemfuno zemiyalelo.
- 2. Kwi-adhesive yecandelo le-AB, kufuneka lixutywe ngokupheleleyo ngaphambi kokusetyenziswa. Akukho zimbombo ezifileyo ezinokushiywa, ngaphandle koko aziyi kuqina.
- 3. I-adherend kufuneka icoceke kwaye ingabi namanzi (ngaphandle kwe-adhesive yokunyanga ngaphantsi kwamanzi).
- 4. Ukufezekisa amandla aphezulu okudibanisa, gcoba ukunamathela kangangoko kunokwenzeka.
- 5. Umgangatho woyilo oludityanisiweyo oludityanisiweyo lumisela amandla ebhondi.
- 6. Xa usebenzisa i-adhesive, qiniseka ukuba uyilungiselele kwaye uyisebenzise ngokukhawuleza. Musa ukuyishiya ixesha elide. Ukuba iphiliswa ngokukhawuleza, akufanelekanga ukuba ibe ngaphezu kwemizuzu emi-2.
- 7. Ukuba ufuna amandla aphezulu kunye nokuphilisa ngokukhawuleza, unokutshisa ngokuxhomekeke kwimeko. Xa usebenzisa i-glue, akufanele ibe nzima kakhulu. Ngokuqhelekileyo, i-0.5mm ilungile. Ukuqina kweglue, ngakumbi umphumo wokudibanisa.
- 8. Xa udibanisa izinto, kungcono ukufaka uxinzelelo okanye uzilungise ngee-clamps.
- 9. Ukufezekisa amandla aphezulu, kungcono ukushiya iiyure ezingama-24 emva kokudibanisa.
- 10. Kwi-single-component solvent-esekelwe okanye emanzini-emixube esekwe, qiniseka ukuba uyixuba ngokulinganayo xa usebenzisa.
- 11. I-solvent-esekelwe kwiimveliso, emva kokufaka iglue, qiniseka ukuba uyivumele ipholile ide ingabikho incangathi ngaphambi kokudibanisa.
