Izindlu ze-EVA (ethylene vinyl acetate) ziya ngokuya ziduma ngenxa yezindawo zazo ezingangeni manzi nezimangelengele. Lawa makesi asetshenziswa kakhulu ukuvikela izinto zikagesi, amakhamera, nezinye izinto ezithambile emanzini, othulini, nomthelela. Inqubo yokukhiqiza amacala e-EVA angangeni manzi futhi aqinile ihlanganisa izinyathelo ezimbalwa ezibalulekile zokuqinisekisa ukuthi umkhiqizo wokugcina uhlangabezana nezindinganiso zekhwalithi ephezulu kakhulu. Kulesi sihloko, sizohlola inqubo yokukhiqiza aikesi le-Eva elingangeni manzi futhi eliqinile, kusukela ekukhethweni kwezinto ezibonakalayo kuya ekuhlolweni kokugcina komkhiqizo.
Ukukhetha okubalulekile
Ukukhiqizwa kwamacala angangeni manzi futhi aqinile e-EVA okuvikela kuqala ngokukhethwa ngokucophelela kwezinto zekhwalithi ephezulu ze-EVA. I-EVA iyi-copolymer ye-ethylene ne-vinyl acetate, eyenza into ehlala isikhathi eside, eguquguqukayo, nengenamanzi. Inqubo yokukhetha impahla ihlanganisa ukukhetha ibanga elifanele le-EVA ukuze kuhlangatshezwane nezidingo ezithile zendawo ebiyelwe engangeni manzi kanye nemangelengele. Okubalulekile kwe-EVA kufanele kube nebhalansi efanelekile yobulukhuni nokuvumelana nezimo ukuze kunikeze ukuvikeleka okuphezulu kokuqukethwe.
Ukubumba
Uma impahla ye-EVA isikhethiwe, isinyathelo esilandelayo senqubo yokukhiqiza inqubo yokubumba. Okubalulekile kwe-EVA kuyashiswa futhi kujovelwe esikhunjeni ukuze kwakheke ikesi lewashi ngomumo nosayizi oyifunayo. Isikhunta siklanywe ngokucophelela ukuze kuqinisekiswe ukufanelana okunembayo nesisetshenziswa kagesi noma ezinye izinto eziqukethwe ebhokisini. Inqubo yokubumba ibalulekile ekuzuzeni izakhiwo ezingangeni manzi nezimangelengele zegobolondo le-EVA, njengoba inquma ukwakheka okuphelele nobuqotho bomkhiqizo wokugcina.
Ukubeka uphawu nokuhlanganisa
Ngemuva kokubumba impahla ye-EVA ibe yisimo oyifunayo, isinyathelo esilandelayo ukuvala nokunamathisela. Izindlu ze-EVA ezingangeni manzi zidinga isivalo esingangeni moya ukuze kuvinjelwe amanzi nothuli ekungeneni endlini. Sebenzisa amasu okuvala akhethekile afana ne-high frequency welding noma ukuvala ukushisa ukuze udale ama-seam namajoyinti angangeni amanzi. Ukwengeza, izindlela zokubopha zisetshenziselwa ukuthuthukisa ubuqotho besakhiwo secala, ukuqinisekisa ukuthi lingakwazi ukumelana nemithelela kanye nokuphathwa kabi.
Ukuqinisa kanye ne-padding
Ukuthuthukisa ukuqina kwegobolondo le-EVA, izinto zokuqinisa kanye nezigcwalisi ziyengezwa ngesikhathi senqubo yokukhiqiza. Izinto zokuqinisa ezifana neyiloni noma i-fiberglass zihlanganiswe esakhiweni se-EVA ukuze zinikeze amandla engeziwe nokuqina. Izinto zokupakisha ezifana negwebu noma ulwelwesi lwevelvet nazo zisetshenziselwa ukugoqa nokuvikela izinto ezivalekile ekungqongqozeni nasekuklwebheni. Inhlanganisela yokuqinisa kanye ne-padding iqinisekisa ukuthi ikesi le-EVA linikeza ukuvikeleka okuphezulu ngenkathi igcina idizayini yayo engasindi futhi ephathekayo.
Ukuhlola Nokulawula Ikhwalithi
Uma inqubo yokukhiqiza isiqediwe, igobolondo le-EVA elingangeni manzi futhi eliqinile lizohlolwa ngokuqinile kanye nezinyathelo zokulawula ikhwalithi. Ukuhlolwa okuhlukahlukene, okuhlanganisa ukuhlolwa kokucwiliswa emanzini, ukuhlolwa komthelela, nokuhlolwa kokuqina, kwenziwa ukuze kuqinisekiswe ukuthi icala liyahlangabezana nezindinganiso ezinqunyiwe zokuvimbela amanzi kanye nokumangelengele. Ukuhlolwa kokulawulwa kwekhwalithi kwenziwa ukuze kubhekwe ukuthi akhona yini amaphutha noma amaphutha emabhokisini, ukuqinisekisa ukuthi imikhiqizo yekhwalithi ephezulu kuphela ekhishelwa emakethe.
ukuhlolwa komkhiqizo wokugcina
Isinyathelo sokugcina senqubo yokukhiqiza ukuhlola ibhokisi le-EVA eliqediwe. Ibhokisi ngalinye lihlolwa ngokucophelela ukuthi alikho yini iphutha lokukhiqiza, njengama-seams angalingani, amalunga abuthakathaka, noma ukuvimbela amanzi okwanele. Inqubo yokuhlola ihlanganisa nokuhlola ubuhle kanye nokusebenza kwamabhokisi ukuze kuqinisekiswe ukuthi ahlangabezana nezindinganiso ezidingekayo zokuvimbela amanzi kanye nokuqina. Noma yimaphi amacala azokhonjwa futhi alungiswe ngaphambi kokuthi apakishwe futhi athunyelwe ekhasimendeni.
Kafushane, ukukhiqizwa kwamacala e-EVA angangeni manzi futhi aqinile kuhilela inqubo ecophelelayo ehlanganisa ukukhethwa kwezinto ezibonakalayo, ukubumba, ukufakwa uphawu nokunamathisela, ukuqinisa nokugcwalisa, ukuhlola nokulawulwa kwekhwalithi, nokuhlolwa komkhiqizo wokugcina. Ngokunamathela ezindinganisweni eziqinile zekhwalithi nokusebenzisa ubuchwepheshe bokukhiqiza obuphambili, abakhiqizi bangaqinisekisa ukuthi amakesi e-EVA anokuvimbela amanzi okuhle kakhulu kanye nokuqina, anikeze ukuvikeleka okuthembekile kwezinto ezibalulekile ezindaweni ezahlukahlukene. Njengoba isidingo sabathengi sokuhlala isikhathi eside, izixazululo zokugcina amanzi ziqhubeka nokukhula, ukukhiqizwa kwamabhokisi e-EVA ekhwalithi ephezulu kusabalulekile ukuze kuhlangatshezwane nalezi zidingo.
