Ngaba kukho nayiphi na imigangatho yesizwe okanye yamazwe ngamazwe yovavanyo lomgangatho wengxowa ye-EVA?

Ngaba kukho nayiphi na imigangatho yelizwe okanye yehlabathi ye-EVA baguvavanyo lomgangatho?
Iingxowa ze-EVA, oko kukuthi, iingxowa ezenziwe nge-ethylene-vinyl acetate copolymer (EVA), zisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ngenxa yokukhanya kwazo, ukuqina kunye nokusebenza kakuhle kwe-cushioning. Ukuvavanywa komgangatho weengxowa ze-EVA, kukho ngokwenene uthotho lwemigangatho yelizwe kunye neyamazwe ngamazwe ukuqinisekisa ukhuseleko kunye nokuthembeka kweemveliso. Nantsi eminye imigangatho ephambili yovavanyo lomgangatho wengxowa ye-EVA:

Imigangatho yamazwe ngamazwe

Ziziphi izinto zovavanyo ezibandakanyiweyo kumgangatho we-ASTM D1043?

Umgangatho we-ASTM D1043 ikakhulu ubandakanya ukuvavanywa kwezixhobo zeplastiki phantsi kotshintsho lweqondo lobushushu ukumisela iimpawu zabo zokuqina. Ezi zilandelayo zezinye zezinto zovavanyo ezibandakanyiweyo kumgangatho we-ASTM D1043:

Ukuqina kweTorsional: Ukuvavanya ukuqina kobunzima bezinto zeplastiki kumaqondo obushushu ahlukeneyo, eyona parameter ibalulekileyo yokulinganisa amandla ezinto zokuxhathisa ukuguquguquka kwe-torsional.

Ukuxhomekeka kobushushu: Ukuvavanya indlela ukuqina kobunzima bezinto zeplastiki eziguqukayo kunye nobushushu, obubalulekileyo ekuqondeni ukusebenza kwezinto phantsi kweemeko ezahlukeneyo zokusingqongileyo.

I-Torsional creep: Ukulinganisa i-torsion deformation yezinto zeplastiki ngokuhamba kwexesha phantsi kwe-torque rhoqo ukuvavanya ukuzinza kwexesha elide lezinto.

Ukuphumla kweTorsional: Ukuvavanya i-torque yezinto zeplastiki phantsi kwe-torsional deformation rhoqo ekuhambeni kwexesha ukuqonda iimpawu zokuphumla koxinzelelo lwento.

Umgangatho we-ASTM D1043 ubonelela ngendlela yokuvavanya ezi zikhombisi zokusebenza kwezixhobo zeplastiki ngovavanyo lwe-torsion, olubaluleke kakhulu malunga nokukhethwa kwezinto, ukuyila kwemveliso kunye nokulawula umgangatho. Ngokusebenzisa ezi zinto zovavanyo, ukuthembeka kunye nokuqina kwezixhobo zeplastiki kwizicelo ezahlukeneyo kunokuqinisekiswa.
