Ike ike na elongation na nkwụsịtụ: A na-atụle ike nkwụsịtụ na elongation na nkwụsị nke ihe site na ule nyocha iji gosipụta ihe eji arụ ọrụ na nkwụsi ike nke akpa EVA.

Nnwale nrụrụ na-adịgide adịgide na-adịgide adịgide: Kpebie mkpakọ na-adịgide adịgide nke ihe n'okpuru nrụgide ụfọdụ iji nyochaa ịdịte aka nke akpa EVA

2. Thermal arụmọrụ ule
Nnwale arụmọrụ thermal na-elekwasị anya na arụmọrụ nke akpa EVA n'okpuru ọnọdụ okpomọkụ dị elu:

Ebe mgbaze na nkwụsi ike ọkụ: A na-enyocha ebe mgbaze na nkwụsi ike nke ihe EVA site na nyocha calorimetry dị iche (DSC) na nyocha thermogravimetric (TGA)

Nguzogide ịka nká: Nwalee nguzogide ịka nká nke akpa EVA na gburugburu okpomọkụ dị elu iji hụ na ngwaahịa ahụ ka nwere ike ịnọgide na-arụ ọrụ nke ọma mgbe ejiri ya ogologo oge.

3. Nyocha arụmọrụ kemịkalụ
Nnwale arụmọrụ kemịkalụ na-enyocha nguzogide nke akpa EVA na ihe kemịkal:

Nguzogide corrosion kemịkalụ: na-enyocha nguzogide nke akpa EVA na acid, alkali, nnu na ihe ndị ọzọ kemịkalụ.

Mgbochi mmanụ: na-anwale nkwụsi ike na nguzogide corrosion nke akpa EVA na mmanụ mmanụ

4. Nnwale mgbanwe gburugburu ebe obibi
Nnwale mgbanwe gburugburu ebe obibi na-enyocha ngbanwe nke akpa EVA na ihe gburugburu ebe obibi:

Nnwale nguzogide ihu igwe: na-achọpụta nguzogide nke akpa EVA na ụzarị ultraviolet, iru mmiri na mgbanwe okpomọkụ

Nnwale nguzogide okpomọkụ dị ala: na-enyocha arụmọrụ nke akpa Eva na gburugburu okpomọkụ dị ala

5. Environmental standard test
Nnwale ọkọlọtọ gburugburu ebe obibi na-achọpụta na akpa EVA na-emezu ihe ndị chọrọ gburugburu ebe obibi na enweghị ihe ndị na-emerụ ahụ:

Ntuziaka RoHS: Ntuziaka na-amachibido iji ụfọdụ ihe dị ize ndụ na ngwa eletriki na eletrọnịkị. Ngwa nke ihe EVA na ngwa eletrọnịkị kwesịrị irube isi na ntuziaka a

Iwu REACH: Iwu EU na ndebanye aha, nyocha, ikike na mmachi kemịkalụ. Mmepụta na ojiji nke ihe EVA kwesịrị ịgbaso ihe achọrọ nke Regulation REACH

6. Nnyefe na bee ike ule
Nnwale pụrụ iche maka ihe nkiri Eva:

Nnwale nnyefe: na-enyocha nnyefe ọkụ nke ihe nkiri EVA, nke dị mkpa karịsịa maka ngwa dị ka oghere anyanwụ.

Nnwale ike peel: na-anwale ike bee n'etiti ihe nkiri EVA na iko na ihe azụ azụ iji hụ na ntụkwasị obi nke nkwakọ ngwaahịa.

Site na ihe nnwale ndị a dị n'elu, enwere ike nyochaa ogo ngwugwu EVA nke ọma iji hụ na ha na-egbo mkpa nke ọnọdụ ngwa dị iche iche. Mgbe ị na-emepụta ma na-eji ihe EVA, ụlọ ọrụ kwesịrị irube isi na ụkpụrụ mba ụwa, mba na ụlọ ọrụ dị mkpa iji hụ na ịdịmma na nchekwa ngwaahịa.
