Isingeniso Somkhiqizo
Amagilavu engalo amade ezilwane alahlwayo aklanyelwe ngokukhethekile ukusetshenziswa kwamadlelo, enziwe nge-60% ye-polyethylene vinyl acetate copolymer (EVA) kanye no-40% we-polyethylene (PE). Okulandelayo kuzochaza umkhiqizo ngokuningiliziwe mayelana nezici ezibonakalayo, ukuqina kwamagilavu, ukuguquguquka nokuvikeleka kwemvelo. Okokuqala, impahla ye-60% EVA + 40% PE yenza le glavu ibe nokuthambile okuhle nokunwebeka. Impahla ye-EVA iyimpahla yokwenziwa enokuthamba okuhle kakhulu nokunwebeka, okungenza igilavu ilingane kangcono nesandla, ikhulise ukunethezeka futhi inikeze ukuguquguquka okungcono kokusebenza. Izinto ze-PE ziyi-polymer ene-elasticity enhle kanye ne-ductility, okwenza amagilavu aqine futhi aqine. Lokhu kuhlanganiswa kwezinto kwenza igilavu libe lithambile futhi liqinile.
Okwesibili, amagilavu enziwe ngale nto anokuqina okuhle. Njengoba imisebenzi yokufuya idinga ukuthintana nezilwane, amagilavu kudingeka amelane nokuhuzuka nokuklebhuka. Inhlanganisela ye-EVA ne-PE yenza amagilavu amelane namandla angaphandle njengokuklwebheka, ukudonsa nokushwibilika, futhi andise impilo yesevisi. Ngale ndlela, abasebenzi basemapulazini abasebenzisa leli glavu bangasebenza ngokuphepha isikhathi eside, futhi ngesikhathi esifanayo banciphise imvamisa yokushintshwa kwamagilavu futhi bathuthukise ukusebenza kahle komsebenzi. Ngaphezu kwalokho, izinto zaleli glavu nazo zinezinga elithile lokuvikelwa kwemvelo. I-EVA iyinto evumelana nemvelo engenazo izinto eziyingozi emzimbeni womuntu futhi enganciphisa ngempumelelo ingozi yokungcoliswa kwemvelo. I-PE iwukusetshenziswa kabusha okungase kusetshenziswe kabusha ngemva kokusetshenziswa, ukunciphisa ukusetshenziswa kwemithombo yemvelo kanye nokucindezela kwemvelo. Ngakho-ke, ukusetshenziswa kwe-60% EVA + 40% PE alahlwayo amagilavu engalo amade ezilwane akukwazi nje ukuvikela izandla zodokotela bezilwane noma abasebenzi basemapulazini, kodwa futhi kubangele umthelela omncane emvelweni, ohambisana nomqondo wentuthuko esimeme. Ukufingqa, le glove yengalo ende yezilwane elahlwayo yenziwe ngempahla engu-60% EVA+40% ye-PE. Inokuthamba okuhle nokunwebeka, yandisa impilo yesevisi, futhi inezinga elithile lokuvikelwa kwemvelo. Lezi zici zenza le gilavu ibe yinketho ekahle ekusebenzeni kwepulazi, ihlinzeka ngolwazi olungcono lokusebenza kubasebenzi bamapulazi.
