Izindlu ze-EVA (i-ethylene vinyl acetate) ziya zithandwa ngakumbi ngenxa yokungangeni kwamanzi kunye neempawu ezinqabileyo. Ezi meko zisetyenziswa ngokubanzi ukukhusela izixhobo zombane, iikhamera, kunye nezinye izinto ezibuthathaka kumanzi, uthuli, kunye neempembelelo. Inkqubo yokuveliswa kwamanzi kunye neemeko ze-EVA ezinamandla zibandakanya amanyathelo amaninzi abalulekileyo okuqinisekisa ukuba imveliso yokugqibela ihlangabezana nemigangatho ephezulu yomgangatho. Kweli nqaku, siza kuphonononga inkqubo yokuvelisa aItyala le-Eva elingangenwa ngamanzi kwaye linamandla, ukusuka ekukhethweni kwezinto ezibonakalayo ukuya ekuhlolweni kwemveliso yokugqibela.
Ukukhetha izinto eziphathekayo
Ukuveliswa kweemeko zokukhusela ze-EVA ezingenamanzi kunye neziqinileyo ziqala ngokukhethwa ngokucophelela kwezinto eziphezulu ze-EVA. I-EVA yicopolymer ye-ethylene kunye ne-vinyl acetate, idala into ehlala ixesha elide, eguquguqukayo, kunye nesixhobo sokungena kwamanzi. Inkqubo yokukhetha izinto eziphathekayo ibandakanya ukukhetha ibakala elifanelekileyo le-EVA ukuhlangabezana neemfuno ezithile zokuvalwa kwamanzi kunye ne-rugged. Izinto ze-EVA kufuneka zibe nebhalansi efanelekileyo yobunzima kunye nokuguquguquka ukubonelela ngokhuseleko oluphezulu lweziqulatho.
Ukubumba
Nje ukuba kukhethwe izinto ze-EVA, inyathelo elilandelayo kwinkqubo yokuvelisa yinkqubo yokubumba. Izinto ze-EVA ziyafudunyezwa kwaye zifakwe kwi-mold ukuze zenze i-watch case kwi-shape efunwayo kunye nobukhulu. Umngundo ucetywe ngononophelo ukuqinisekisa ukufaneleka okuchanekileyo kunye nesixhobo sombane okanye ezinye izinto eziqulethwe kwibhokisi. Inkqubo yokubumba ibalulekile ekufezekiseni ukungenwa kwamanzi kunye neepropathi ezirhabaxa zeqokobhe le-EVA, njengoko imisela ulwakhiwo jikelele kunye nokuthembeka kwemveliso yokugqibela.
Ukutywinwa kunye nokudibanisa
Emva kokubumba izinto ze-Eva kwisimo esifunwayo, inyathelo elilandelayo kukutywina kunye ne-gluing. Izindlu ze-EVA ezingenamanzi zifuna isitywina esingenamoya ukukhusela amanzi kunye nothuli ekungeneni kwindlu. Sebenzisa ubuchule obuchwephesha bokutywina obufana ne-high frequency welding okanye ukutywinwa kobushushu ukwenza imithungo engangeni manzi kunye namalungu. Ukongezelela, iindlela zokudibanisa zisetyenziselwa ukunyusa ukunyaniseka kwesakhiwo setyala, ukuqinisekisa ukuba inokumelana neempembelelo kunye nokuphathwa kakubi.
Ukuqiniswa kunye ne-padding
Ukomeleza ukuqina kweqokobhe le-EVA, izixhobo zokuqinisa kunye nezihluzi zongezwa ngexesha lenkqubo yokuvelisa. Izinto zokuqinisa ezifana ne-nylon okanye i-fiberglass idibaniswe kwisakhiwo se-EVA ukubonelela ngamandla ongezelelweyo kunye nokuqina. Izixhobo zokugquma ezifana negwebu okanye i-velvet lining zikwasetyenziselwa ukunyusa nokukhusela izinto ezivaliweyo ekunkqonkqozeni nasekukrwelweni. Ukudibanisa ukuqiniswa kunye ne-padding kuqinisekisa ukuba i-EVA case ibonelela ngokhuseleko oluphezulu ngelixa igcina uyilo olulula kunye noluphathwayo.
Uvavanyo kunye noLawulo loMgangatho
Nje ukuba inkqubo yokuvelisa igqitywe, iqokobhe le-EVA elingangeni manzi kunye nelomeleleyo liya kuvavanywa ngokuqatha kunye namanyathelo olawulo lomgangatho. Iimvavanyo ezahlukeneyo, kubandakanywa iimvavanyo zokuntywiliselwa emanzini, iimvavanyo zempembelelo, kunye neemvavanyo zokuqina, zenziwa ukuqinisekisa ukuba ityala liyahlangabezana nemigangatho emiselweyo yokungangeni kwamanzi kunye nemigangatho. Ukuhlolwa kokulawulwa komgangatho kuqhutyelwa ukujonga ukuba kukho naziphi na iziphene okanye iziphene kwiibhokisi, ukuqinisekisa ukuba kuphela iimveliso ezikumgangatho ophezulu ezikhutshwa kwimarike.
ukuhlolwa kwemveliso yokugqibela
Isinyathelo sokugqibela kwinkqubo yokuvelisa kukuhlolwa kwebhokisi ye-EVA egqityiweyo. Ibhokisi nganye ihlolwe ngononophelo naziphi na iziphene zokuvelisa, ezifana ne-seams engalinganiyo, amajoyina abuthathaka, okanye ukungonelanga kwamanzi. Inkqubo yokuhlola ibandakanya ukujonga i-aesthetics jikelele kunye nokusebenza kweebhokisi ukuqinisekisa ukuba zihlangabezana nemigangatho efunekayo yokungangeni kwamanzi kunye nokuqina. Naziphi na iimeko ezineziphene ziya kuchongwa kwaye zilungiswe phambi kokuba zipakishwe kwaye zithunyelwe kumthengi.
Isishwankathelo, ukuveliswa kwamatyala e-EVA angangeni manzi kunye namandla anamandla abandakanya inkqubo ecokisekileyo ebandakanya ukukhethwa kwezinto, ukubumba, ukutywinwa kunye ne-gluing, ukuqiniswa kunye nokuzaliswa, ukuvavanywa kunye nokulawula umgangatho, kunye nokuhlolwa kokugqibela kwemveliso. Ngokuthobela imigangatho yomgangatho ongqongqo kunye nokusebenzisa iteknoloji yokuvelisa ephucukileyo, abavelisi banokuqinisekisa ukuba iimeko ze-EVA zinokungangeni kwamanzi okugqwesileyo kunye nokuqina, ukubonelela ngokhuseleko oluthembekileyo lwezinto ezixabisekileyo kwiindawo ezahlukeneyo. Njengoko imfuno yabathengi yokuqina, izisombululo zokugcina amanzi ziqhubeka zikhula, ukuveliswa kweebhokisi ze-EVA ezikumgangatho ophezulu kuhlala kubalulekile ukuhlangabezana nezi mfuno.
