Izinamathiselo zezentengiselwano, njengezinto ezibalulekile embonini yesimanje kanye nokukhiqizwa kwansuku zonke, zinokusebenza okuxhumene kakhulu nemvelo yohlelo lokusebenza. Izimo zohlelo lokusebenza ezihlukene zibeka izimfuno ezihlukene emazingeni okushisa okunamathelayo, ukumelana nomswakama, ukumelana namakhemikhali, namandla emishini. Ngakho-ke, ukuqonda indawo esebenzayo kubalulekile ukuze kuqinisekiswe ukuhlangana okuphumelelayo.
1. Ukushisa Kwegumbi, Imvelo Eyomile
Iningi elivamile-Izinto ezinamathelayo eziyinjongo (ezifana nama-acrylates nama-epoxies) zisebenza kahle ezindaweni ezinezinga lokushisa legumbi (20-25℃) kanye nomswakama ophakathi. Lezi zindawo zivamile emahhovisi, ezindlini, kanye nomhlangano wezimboni omncane, futhi zifanele izinto zokubopha njengephepha, ipulasitiki, nokhuni. Lezi zinamatheliso zelapha ngokushesha futhi kulula ukuzisebenzisa, kodwa ukuchayeka isikhathi eside kumswakama kungase kuholele ekulahlekelweni kwamandla ebhondi.
2. I-High Temperature Environment
-Izinto ezinamathelayo ezikwazi ukumelana nezinga lokushisa{1}}eziphezulu ngokuvamile zidingeka emikhakheni efana nokuhlanganisa impahla yezimboni kanye nokukhiqizwa kwezimoto. Isibonelo, izinto zokunamathelisa i-silicone zihlala zizinzile emazingeni okushisa asuka -ku-50℃kuya ku-300℃, okuwenza afanelekele izingxenye zenjini zokuvala noma{8}}amapayipi okushisa aphezulu. I-Phenolic resin adhesives, ngakolunye uhlangothi, ingakwazi ukumelana namazinga okushisa aphezulu (kufika ku-500 degree) futhi ivame ukusetshenziselwa ukuhlanganisa izinga lokushisa eliphezulu kwezingxenye zensimbi. Lezi zindawo zidinga izinto ezinamathelayo ezinokuzinza okuhle kakhulu kwe-thermal kanye ne-oxidative.
3. Izindawo Ezinomswakama noma Ezingaphansi Kwamanzi
Izicelo ezifana nokwakhiwa kodonga lwamakhethini nokulungiswa komkhumbi zidinga ama-adhesives anokumelana namanzi kanye nokumelana nokungena. Izinamathiselo ze-polyurethane, ngenxa yamaqembu azo aqinile e-polar, zakha izibopho eziqinile kuma-substrates amanzi futhi zingasetshenziswa ngisho nasekwakheni ngaphansi kwamanzi. I-Epoxy-izinto zokunamathisela ezilungisiwe, ngokwengeza izigcwalisi ze-hydrophobic, zithuthukisa ukumelana kwazo nokugqwala kwesifutho sikasawoti futhi ngenxa yalokho zilungele ukusetshenziswa olwandle.
4. Izindawo Ezonakalisa Ngamakhemikhali
Kulabhorethri noma ezitshalweni zamakhemikhali, izinto ezinamathelayo kufanele zimelane nokugqwala okuvela emithonjeni yamakhemikhali njengama-acids, ama-alkali, nezinyibilikisi. Izinamatheliso ze-fluororubber noma ze-polyimide, ngenxa yokungangeni kwamakhemikhali, zingamelana{1}}nokuxhumana isikhathi eside nezinto ezigqwala kakhulu futhi zisetshenziswa kakhulu ekuvaleni amapayipi noma ekuhlanganiseni okuyisivikelo.
Kafushane, ama-adhesives okuhweba afaneleka ezindaweni ezihlukahlukene, futhi uhlobo olufanele kufanele lukhethwe ngokusekelwe ezimweni ezithile zokusebenza. Ukuhlolwa okufanele kwezinto ezifana nezinga lokushisa, umswakama, nokuchayeka kwamakhemikhali kubalulekile ukuze kusetshenziswe ngokugcwele ukusebenza kwe-adhesive nokuqinisekisa ukusetshenziswa okuphephile nokuhlala isikhathi eside.
