Indlela yokuvavanya umgangatho weengxowa ze-EVA?

Uvavanyo lomgangatho weIingxowa ze-EVAyinkqubo yovavanyo olubanzi olubandakanya imiba emininzi, kubandakanywa iimpawu ezibonakalayo, iimpawu zekhemikhali, imigangatho yokukhuselwa kokusingqongileyo kunye neminye imilinganiselo. Ezi zilandelayo zezinye izinto eziphambili zovavanyo kunye neendlela:

1. Uvavanyo lwentsebenzo yomzimba
Uvavanyo lokusebenza komzimba ikakhulu luvavanya iipropathi ezisisiseko zengxowa ye-EVA, kubandakanya:

Uvavanyo lobunzima: Ubunzima beengxowa ze-EVA ngokuqhelekileyo zivavanywa ngu-Shore A uvavanyo lobunzima, kwaye uluhlu oluqhelekileyo lobunzima luphakathi kwe-30-70

Amandla okuqina kunye nobude ngexesha lekhefu: Amandla okuqina kunye nobude ekuqhekekeni kwezinto zilinganiswa ngovavanyo lokuqina ukubonisa iimpawu zoomatshini kunye nokuzinza kwengxowa ye-EVA.

Uvavanyo olusisigxina lokunyanzeliswa kwe-deformation: Misela ukunyanzeliswa kwe-deformation yesigxina phantsi koxinzelelo oluthile lokuvavanya ukuqina kwesikhwama se-EVA.

2. Uvavanyo lokusebenza kwe-thermal
Uvavanyo lokusebenza kwe-thermal lugxile ekusebenzeni kweengxowa ze-EVA phantsi kweemeko eziphezulu zokushisa:

Indawo yokunyibilika kunye nokuzinza kwe-thermal: Indawo yokunyibilika kunye nokuzinza kwe-thermal yezinto ze-EVA zivavanywa nge-calorimetry ye-scanning ehlukeneyo (DSC) kunye nohlalutyo lwe-thermogravimetric (TGA)

Ukumelana nokuguga kobushushu: Vavanya ukuguga kweengxowa ze-EVA kwindawo yobushushu obuphezulu ukuqinisekisa ukuba imveliso isenokugcina ukusebenza kakuhle emva kokusetyenziswa kwexesha elide.

3. Uvavanyo lokusebenza kweekhemikhali
Uvavanyo lokusebenza kwemichiza luvavanya ukuxhathisa kwengxowa ye-Eva kwizinto zekhemikhali:

Ukunganyangeki kwe-Chemical corrosion: ivavanya ukuxhathisa kwengxowa ye-Eva kwi-asidi, ialkali, ityuwa kunye nezinye izinto zekhemikhali.

Ukuchasana kwe-oyile: kuvavanya ukuzinza kunye nokumelana nokubola kwengxowa ye-EVA kwindawo yeoli

4. Uvavanyo lokuziqhelanisa nokusingqongileyo
Uvavanyo lokuziqhelanisa nokusingqongileyo luvavanya ukuziqhelanisa nengxowa ye-EVA kwizinto zokusingqongileyo:

Uvavanyo lokuxhathisa imozulu: ibona ukuxhathisa kwengxowa ye-EVA kwimitha ye-ultraviolet, ukufuma kunye notshintsho lobushushu

Uvavanyo lokumelana nobushushu obuphantsi: uvavanya ukusebenza kwengxowa ye-Eva kwindawo yobushushu obuphantsi

5. Uvavanyo lomgangatho wokusingqongileyo
Uvavanyo lomgangatho wokusingqongileyo luqinisekisa ukuba ingxowa ye-EVA iyahlangabezana neemfuno zokusingqongileyo kwaye ayiqulathanga izinto eziyingozi:

I-RoHS Directive: Umyalelo othintela ukusetyenziswa kwezinto ezithile ezinobungozi kwizixhobo zombane neze-elektroniki. Ukusetyenziswa kwezixhobo ze-EVA kwizixhobo zombane kufuneka kuthotyelwe lo myalelo

I-REACH Regulation: Imimiselo ye-EU malunga nokubhaliswa, ukuvavanya, ukugunyaziswa kunye nokunciphisa imichiza. Ukuveliswa kunye nokusetyenziswa kwezinto ze-EVA kufuneka zihambelane neemfuno zoMmiselo we-REACH

6. Ukuhanjiswa kunye novavanyo lwamandla e-peel
Uvavanyo olukhethekileyo lwefilimu ye-Eva:

Uvavanyo lokudluliselwa: kuvavanya ukuhanjiswa kokukhanya kwefilimu ye-EVA, ebaluleke kakhulu kwizicelo ezinje ngeepaneli zelanga.

Uvavanyo lwamandla e-Peel: uvavanyo lwamandla e-peel phakathi kwefilimu ye-EVA kunye neglasi kunye nezixhobo ze-backplane ukuqinisekisa ukuthembeka kokupakishwa

Ngokusebenzisa ezi zinto zovavanyo zingentla, umgangatho weepakethe ze-EVA unokuvavanywa ngokupheleleyo ukuqinisekisa ukuba ziyahlangabezana neemfuno zeemeko ezahlukeneyo zesicelo. Xa uvelisa kwaye usebenzisa izinto ze-EVA, iinkampani kufuneka zithobele ngokungqongqo imigangatho yamazwe ngamazwe, yelizwe kunye neyeshishini ukuqinisekisa umgangatho wemveliso kunye nokhuseleko.
