Luhlobo luni lwefilimu yokuncamathelisa eshushu enyibilikayo enamandla okubopha aqinileyo?
Iiglu ezinyibilikayo ezishushu zithathwa njengezincamathelisi ezinobuhlobo nokusingqongileyo. Kakade ke, iimveliso zefilimu ezinamathelayo ezishushu ezenziwe ngeeglu ezinyibilikayo ezishushu nazo zinobuhlobo nokusingqongileyo. Yingakho iifilimu ezinamathelayo ezishushu zifumana ingqalelo engakumbi namhlanje.
Ifilimu yokuncamathelisa eshushu inokwahlulwa ibe ziintlobo ezininzi ngokwezinto ezisetyenzisiweyo. Ezona zixhaphakileyo yifilimu yokuncamathelisa eshushu ye-EVA, ifilimu yokuncamathelisa eshushu ye-TPU, ifilimu yokuncamathelisa eshushu ye-PA, ifilimu yokuncamathelisa eshushu ye-PES, kunye nefilimu yokuncamathelisa eshushu ye-PO. Iintlobo, amagama eekhemikhali ahambelanayo yi-ethylene-vinyl acetate polymer, i-thermoplastic polyurethane, i-polyamide, i-polyester, i-polyolefin. Ezi ntlobo zeepolymers ezineemolekyuli eziphezulu zineempawu zazo, ngoko ke ukusebenza kweemveliso zefilimu yokuncamathelisa eshushu eyenziweyo nako kwahlukile, kodwa njengemveliso yokuncamathelisa, eyona mpawu yokusebenza ibaluleke kakhulu inokuba ngamandla okubopha. Loluphi uhlobo lwemveliso yefilimu yokuncamathelisa eshushu enamandla okunamathela angcono?
Enyanisweni, akukho ndlela yokunika impendulo echanekileyo kumbuzo wokuba loluphi uqina lwebhondi olungcono. Ngenxa yokuba iintlobo ezahlukeneyo zeglue zineempawu ezahlukeneyo zebhondi kwizinto ezahlukeneyo, amandla eglue abonakalayo nawo ahlukile. Umzekelo, isiphumo seglue sePES hot melt adhesive film kwisinyithi ngokubanzi singcono kuneseTPU hot melt adhesive film, kodwa uhlobo oluthile lweglue yeTPU hot melt adhesive film lunokuba ngcono kakhulu kunePES hot melt adhesive film yokuncamathelisa kwiiplastiki zePVC. Ke ngoko, umbuzo wokuba loluphi uqina lwebhondi olungcono awucaci kakhulu kwaye kunzima ukuwuphendula. Ngokubanzi, uhlobo oluthile lwezinto lunokunikwa ngaphambi kokuba lugqitywe ngokusekelwe kumava.
Kakade ke, kudla ngokuba nzima ukugweba ngokuchanekileyo ukuba loluphi uhlobo lwefilimu yokuncamathelisa eshushu elungele ukubopha emva kokuba uhlobo oluthile lwezinto lunikiwe. Singagweba kuphela isiphumo esiqhelekileyo ngokusekelwe kwimeko eqhelekileyo namava. Uqinisekiso lokugqibela lusafuna uvavanyo lovavanyo ukuze kuqinisekiswe ukuba luchaneke kakhulu. Kuba nokuba izinto ziyafana, umahluko kuburhabaxa bomphezulu, uxinzelelo lomphezulu kunye nezinye izinto ekugqibeleni ziya kuchaphazela ukubopha kwezinto ngenxa yomahluko kwinkqubo.
