Intshayelelo yeMveliso
Iiglavu zengalo ezinde zezilwanyana ezilahlwayo zenzelwe ngokukodwa ukusetyenziswa kwedlelo, zenziwe nge-60% ye-polyethylene vinyl acetate copolymer (EVA) kunye ne-40% ye-polyethylene (PE). Oku kulandelayo kuya kuchaza imveliso ngokweenkcukacha malunga neempawu eziphathekayo, ukuqina kweglavu, ukuguquguquka kunye nokukhuselwa kwendalo. Okokuqala, izinto ze-60% EVA + 40% PE yenza le glavu ibe nokuthamba okuhle kunye nokuqina. Impahla ye-EVA yimathiriyeli eyenziweyo enokuthamba okugqwesileyo kunye nokunwebeka, okunokwenza iglavu ilingane kakuhle nesandla, yandise intuthuzelo kunye nokubonelela ngokuguquguquka okungcono kokusebenza. Impahla ye-PE i-polymer ene-elasticity enhle kunye ne-ductility, eyenza iiglavu zihlale kwaye ziqinile. Oku kudityaniswa kwezixhobo kwenza iglavu ibe yithambile kwaye yomelele.
Okwesibini, iiglavu ezenziwe ngolu hlobo zinokuqina okulungileyo. Kuba imisebenzi yokufuya ifuna ukudibana nezilwanyana, iiglavu kufuneka zixhathise ukukrazuka nokukrazuka. Ukudityaniswa kwe-EVA kunye ne-PE kwenza iiglavu zixhathise amandla angaphandle afana nokukrazula, ukutsala kunye nokukhuhlana, kunye nokwandisa ubomi benkonzo. Ngale ndlela, abasebenzi basefama abasebenzisa le glavu banokusebenza ngokukhuselekileyo ixesha elide, kwaye kwangaxeshanye banciphise ukuphindaphindwa kokutshintshwa kweeglavu kunye nokuphucula ukusebenza kakuhle. Ukongeza, izinto zale glavu nazo zinenqanaba elithile lokukhuselwa kwendalo. I-EVA yinto ehambelana nokusingqongileyo engenazo izinto ezinobungozi kumzimba womntu kwaye inokunciphisa ngokufanelekileyo ingozi yongcoliseko lwendalo. I-PE yinto enokuphinda isetyenziswe kwakhona emva kokusetyenziswa, ukunciphisa ukusetyenziswa kwemithombo yendalo kunye noxinzelelo kwindalo. Ngoko ke, ukusetyenziswa kwe-60% ye-EVA + 40% ye-PE ezilahlayo iiglavu zengalo ezinde zezilwanyana azikwazi ukukhusela kuphela izandla zoogqirha bezilwanyana okanye abasebenzi beefama, kodwa zibangele impembelelo encinci kwindalo, ehambelana nombono wophuhliso oluzinzileyo. Ukushwankathela, le glove yengalo ende yonyango lwezilwanyana yenziwe nge60% EVA+40% imathiriyeli yePE. Inobuhle obuhle kunye no-elasticity, yandisa ubomi benkonzo, kwaye inomlinganiselo othile wokukhuselwa kwendalo. Ezi mpawu zenza le glavu ibe lolona khetho lufanelekileyo kwimisebenzi yeefama, ibonelela ngamava okusebenza angcono kubasebenzi basefama.
