Ngenkqubela phambili eqhubekayo yenzululwazi yemathiriyeli, ifilimu enqamlezayo, njengesixhobo esiphezulu{0}}esihlanganisiweyo sokusebenza, ngokuthe ngcembe ibonisa iingenelo ezizodwa kwiinkalo zoshishino ezininzi. Uyilo olukhethekileyo lwesakhiwo kunye neempawu ezibalaseleyo zomzimba kunye neekhemikhali zenza ukuba kube yinto ebalulekileyo ekukhetheni izinto zokupakisha, ukwakhiwa, i-electronics kunye namanye amashishini. Eli nqaku liza kuzisa iimpawu eziphambili zefilimu enqamlezileyo kunye nexabiso layo lesicelo ngokweenkcukacha.
Amandla aphezulu kunye nokumelana nokukrazula
Enye yeempawu eziphambili zefilimu yomnqamlezo ngamandla ayo omatshini abalaseleyo. Ngokusebenzisa inkqubo ekhethekileyo yokwelula i-biaxial, ifilimu enqamlezileyo inamandla aphezulu okuzibamba kuzo zombini i-longitudinal kunye nezalathiso ezinqamlezayo, iyenza ukuba kube lula ukuphuka okanye ukonakala xa iphantsi kwamandla angaphandle. Olu phawu lwenza ukuba lufaneleke ngakumbi kwizinto zokupakisha ezifuna amandla aphezulu, njengokutya, iyeza kunye nokupakishwa kwemveliso yemveliso, kwaye inokukhusela ngokufanelekileyo iziqulatho kwimpembelelo yangaphandle.
Iipropati ezigqwesileyo zomqobo
Enye inzuzo enkulu yefilimu enqamlezileyo yimpawu zayo ezintle zokuthintela. Ingaba ivalela ioksijini, umphunga wamanzi okanye ezinye iigesi, ifilimu enqamlezileyo inokubonelela ngokhuseleko oluthembekileyo. Olu phawu lwenza ukuba lusetyenziswe ngokubanzi ekugcinweni kokutya, ukukhuselwa kokunyakama kweziyobisi, kunye nokhuseleko lwe-oxidation yemveliso ye-elektroniki. Ngokomzekelo, kwipakethe yokutya, ifilimu enqamlezileyo inokwandisa ngokufanelekileyo ixesha leshelufu kunye nokunciphisa umngcipheko wokutshatyalaliswa kokutya.
Ukumelana neekhemikhali ezilungileyo kunye nokuzinza
Iinwebu ezinqamlezileyo zenziwa ngezinto eziphezulu- zepolymer esebenzayo, ezifana nepolypropylene (PP) okanye ipolyethylene (PE), ezinokumelana nokugqwesa kweekhemikhali. Ingaba i-asidi, i-alkali okanye i-solvent ye-organic, i-membrane ye-cross inokugcina iipropati ezizinzileyo zomzimba kwaye akulula ukuthothisa okanye ukuguqula. Olu phawu luyenza ibe yinto efanelekileyo yokupakisha kunye nezinto ezikhuselayo kwimichiza, amayeza kunye namanye amashishini.
Ukukhuselwa kokusingqongileyo kunye nokusebenziseka kwakhona
Ngokunyuka kolwazi lokusingqongileyo, ukusebenza kokusingqongileyo kweembrane ezinqamlezileyo nako kutsale ingqwalasela enkulu. Iimbumba ezininzi ezinqamlezileyo zenziwe ngezinto ezinokuphinda zisetyenziswe, ezihlangabezana neemfuno zoshishino lwanamhlanje zophuhliso oluzinzileyo. Ukongeza, uyilo lwayo olukhaphukhaphu lukwanceda ekunciphiseni ukusetyenziswa kwamandla ngexesha lokuthuthwa kunye nokunciphisa ngakumbi ukukhutshwa kwekhabhoni.
Ukuqukumbela
Ngamandla ayo aphezulu, iipropathi ezigqwesileyo zomqobo, ukuchasana kweekhemikhali kunye neempawu zokukhusela okusingqongileyo, iimbrane ezinqamlezayo ziye zaba yenye yezinto eziyimfuneko kwishishini lanamhlanje. Ngokuqhubela phambili okuqhubekayo kwetekhnoloji, intsimi yokusetyenziswa kweembrane ezinqamlezayo iya kwandiswa ngakumbi ukuze ibonelele ngezisombululo ezisebenzayo nezithembekileyo kumashishini ahlukeneyo.
