Amathiphu Okusebenzisa Izinamathiselo Ezivamile

Isiphakathi esixhuma izinto ezimbili ngokuvamile sibonakala njengesixazululo esinamanzi futhi siyingxenye yamakhemikhali amahle. Kunezinhlobo eziningi zama-intermediate, ezihlukaniswa ngokuyinhloko ngokunamathela, isimo somzimba, indlela yokuqina kanye nezinto zokunamathela.

Izinto okufanele uziqaphele lapho ukhetha ama-adhesives

Isikhathi sesitoreji

1. 1. Umkhiqizo ngamunye unesikhathi sokugcina. Ngokwezindinganiso zamazwe ngamazwe kanye nezasekhaya, isikhathi sokugcina sibhekisela esikhathini sokugcina endaweni yokushisa yegumbi (24°C). Kuma-adhesive e-acrylic, kungama-20°C.
2. 2. Ngemikhiqizo ye-acrylic, izinga lokushisa liphezulu, isikhathi sokugcina siba sifushane.
3. 3. Ngemikhiqizo-esekelwe emanzini, uma izinga lokushisa lingaphansi -1°C, lizothinta ikhwalithi yomkhiqizo ngokuqondile.

Amandla

1. 1. Ayikho ingcina ye-universal emhlabeni. Kungcono ukusebenzisa izinamathiselo ezikhethekile zokunamathela okuhlukile.
2. I-2.Uma amandla okunamathela ngokwawo ephansi, asikho isidingo sokukhetha imikhiqizo ephezulu-amandla, ngaphandle kwalokho, kuyoba ukuchitha izinsiza nokwandisa izindleko.
3. 3. Ungagxili nje emandleni aphezulu okuqala, kodwa futhi ucabange ukuqina okuhle.
4. 4. Ukusebenza kwezinamatheliso ezilaphayo ezisezingeni eliphezulu kuphakeme kakhulu kunaleyo yegumbi-okunamathelisa okwelapha izinga lokushisa. Uma kudingeka amandla aphezulu nokuqina okuhle, ama-adhesives okwelapha izinga lokushisa eliphezulu kufanele akhethwe.
5. 5. Iglue ye-Cyanoacrylate (502 super glue) akufanele isetshenziselwe izinto ezidinga amandla okubopha okuphezulu ngaphandle kwendawo ephuthumayo noma ukulungiswa kwendawo encane kanye nokukhiqizwa okuqhubekayo.

Abanye

1. 1. I-latex emhlophe ne-urea-formaldehyde glue ayikwazi ukusetshenziselwa ukuhlanganisa insimbi.
2. 2. Uma i-adhesive ebonakalayo iyadingeka, i-polyurethane adhesive, i-optical epoxy adhesive, i-saturated polyester adhesive, kanye ne-polyvinyl acetal adhesive ingasetshenziswa.
3. 3. I-adhesive akufanele igxumeke ekunamatheleni. Isibonelo, i-solvent-based chloroprene adhesive ayikwazi ukusetshenziswa kumabhodi e-polystyrene foam.
4. 4. Izinamathiselo ezine-brittleness ephezulu azifanele ukunamathela izinto ezithambile.

Izinyathelo zokuqapha lapho usebenzisa i-AB glue

1. 1. Ngezinto ezinamathelayo zengxenye ye-AB, sicela uhlanganise ngokuvumelana nezidingo zemiyalelo.
2. 2. Ngokunamathela kwengxenye AB, kufanele inyakaze ngokugcwele ngaphambi kokusetshenziswa. Awekho amakhona afile angashiywa, ngaphandle kwalokho ngeke aqine.
3. 3. I-adherend kumele ihlanzeke futhi ingabi nomswakama (ngaphandle kokunamathiswa okupholisa ngaphansi kwamanzi).
4. 4. Ukuze uthole amandla okubopha okuphezulu, pholisha ukunamathela ngangokunokwenzeka.
5. 5. Ikhwalithi yomklamo ohlangene ohlangene inquma amandla esibopho.
6. 6. Uma usebenzisa i-adhesive, qiniseka ukuthi uyayilungisa futhi uyisebenzise ngokushesha. Ungayishiyi isikhathi eside kakhulu. Uma ukwelapha ngokushesha, akufanele kudlule imizuzu emi-2.
7. 7. Uma ufuna amandla aphezulu kanye nokwelapha okusheshayo, ungawushisa ngokuya ngesimo. Uma usebenzisa i-glue, akufanele ibe mkhulu kakhulu. Ngokuvamile, 0.5mm muhle. Ukuqina kweglue, umphumela wokubopha ube mubi kakhulu.
8. 8. Uma ubopha izinto, kungcono ukufaka ingcindezi noma uzilungise ngama-clamps.
9. 9. Ukuze uzuze amandla aphezulu, kungcono ukuyishiya amahora angu-24 ngemva kokubopha.
10. 10. Ngokwakheka okukodwa-kwengxenye-okusekelwe emanzini noma okususelwe emanzini, qiniseka ukuthi uxukuza ngokulinganayo uma usebenzisa.
11. 11. Ukuze uthole i-solvent-imikhiqizo esekelwe, ngemva kokufaka iglue, qiniseka ukuthi uyayiyeka ipholile kuze kube yilapho ingasakwazi ukunamathela ngaphambi kokunamathisela.
