Iingcebiso zokuSebenzisa i-Adhesives eziqhelekileyo

Umbindi odibanisa izinto ezimbini ubukhulu becala ubonakala njengesisombululo esinamanzi kwaye ungowodidi lweekhemikhali ezintle. Kukho iintlobo ezininzi ze-intermediates, ezihlelwa ngokukodwa ngokunamathela, ifom yomzimba, indlela yokuqina kunye nezinto zokubambelela.

Izinto zokuqaphela xa ukhetha i-adhesives

Ixesha lokugcina

1. 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. 2. Kwiimveliso ze-acrylic, iqondo lokushisa eliphezulu, lifutshane ixesha lokugcina.
3. 3. Kwimveliso ezisekelwe emanzini, ukuba iqondo lobushushu lingaphantsi -1°C, liya kuchaphazela ngqo umgangatho wemveliso.

Amandla

1. 1. Akukho glu emhlabeni jikelele. Kungcono ukusebenzisa i-adhesives ekhethekileyo kwii-adherends ezahlukeneyo.
2. 2.Ukuba amandla okubambelela ngokwawo aphantsi, akukho mfuneko yokukhetha iimveliso eziphezulu - zamandla, ngaphandle koko, kuya kuba yinkcitho yezibonelelo kunye nokunyusa iindleko.
3. 3. Musa ukugxila kuphela kumandla aphezulu okuqala, kodwa qwalasela ukuqina okulungileyo.
4. 4. Ukusebenza okuphezulu-iqondo lokuncamathelisa ukunyanga liphezulu kakhulu kunelo gumbi-lobushushu lokunyanga izinto zokuncamathelisa. Ukuba kufuneka amandla aphezulu kunye nokuqina okuhle, kufuneka kukhethwe izinto ezincamathelayo zokunyanga ubushushu obuphezulu.
5. 5. Iglue ye-Cyanoacrylate (i-502 super glue) ayifanele isetyenziswe kwizinto ezifuna amandla aphezulu okubambisana ngaphandle kwengxakeko okanye ukulungiswa kwendawo encinci kunye nemveliso eqhubekayo.

Abanye

1. 1. I-latex emhlophe kunye ne-urea-formaldehyde glue ayinakusetyenziselwa ukubopha isinyithi.
2. 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. 3. I-adhesive ayifanele ibe yi-corrosive kwi-adherend. Umzekelo, i-solvent-esekelwe kwi-chloroprene adhesive ayinakusetyenziswa kwiibhodi ze-polystyrene foam.
4. 4. I-Adhesives ene-brittleness ephezulu ayifanelekanga ukunamathela izinto ezithambileyo.

Izilumkiso xa usebenzisa iglue ye-AB

1. 1. Ukunamathela kwecandelo le-AB, nceda udibanise ngokweemfuno zemiyalelo.
2. 2. Kwi-adhesive yecandelo le-AB, kufuneka lixutywe ngokupheleleyo ngaphambi kokusetyenziswa. Akukho zimbombo ezifileyo ezinokushiywa, ngaphandle koko aziyi kuqina.
3. 3. I-adherend kufuneka icoceke kwaye ingabi namanzi (ngaphandle kwe-adhesive yokunyanga ngaphantsi kwamanzi).
4. 4. Ukufezekisa amandla aphezulu okudibanisa, gcoba ukunamathela kangangoko kunokwenzeka.
5. 5. Umgangatho woyilo oludityanisiweyo oludityanisiweyo lumisela amandla ebhondi.
6. 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. 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. 8. Xa udibanisa izinto, kungcono ukufaka uxinzelelo okanye uzilungise ngee-clamps.
9. 9. Ukufezekisa amandla aphezulu, kungcono ukushiya iiyure ezingama-24 emva kokudibanisa.
10. 10. Kwi-single-component solvent-esekelwe okanye emanzini-emixube esekwe, qiniseka ukuba uyixuba ngokulinganayo xa usebenzisa.
11. 11. I-solvent-esekelwe kwimveliso, emva kokufaka iglue, qiniseka ukuba uyivumele ipholile ide ingabi yinto encamathelayo ngaphambi kokuba i-gluing.
