Isikhwama Sefriji Sesitoreji Sokudla se-PEVA

I-PEVA iyi-polymer ye-PE ne-EVA, eyingxenye yokuvikela imvelo, ayinaphunga, ithambile futhi ibushelelezi, futhi inomuzwa omuhle. Inani lokuqukethwe kwe-EVA linquma umuzwa wayo kanye nomuzwa wokudonsa. Ukuphakama kokuqukethwe kwe-Eva, kuba ngcono futhi kube nzima umuzwa we-drape. Kunalokho, iqina futhi ilula futhi inokunwebeka okuthile.
I-PEVA ibonakala ngokuthi:
1. ingasetshenziselwa ukuwohloka kwemvelo; Uma ingadingeki, kungakhathaliseki ukuthi ilahliwe noma ishisiwe, ihambisana ngokuphelele nemvelo futhi ngeke ilethe noma yimuphi umonakalo emvelweni.
2. Ngenani, sonke siyazi ukuthi izindleko zezinto ezinobuthi ze-PVC zizoba ishibhile kunezinto ze-PEVA, kodwa intengo yezinto ze-PVC ezingenayo ama-phthalates izobiza kakhulu kunezinto ze-PEVA.
3. Ukuminyana kwezinto ze-PEVA kuphakathi kuka-0.91 no-0.93, kuyilapho ukuminyana kwezinto ze-PVC kungu-1.32, okuphinde kube inzuzo yezinto ze-PEVA, isisindo esilula.
4. Izinto ze-PEVA azinaphunga, ngokungafani ne-Amonian noma amanye amaphunga aphilayo.
5. Izinto ze-PEVA aziqukethe izinsimbi ezisindayo, ngakho zingasetshenziswa ngokuphepha. Kube khona izindinganiso zamazwe ngamazwe zalolu hlobo: EN-71 Ingxenye 3 ne-ASTM-F963, futhi i-PEVA ihambisana ngokugcwele.
I-6, uma ukusetshenziswa kwezinto ze-PEVA ezenziwe ngamathoyizi, kungaqinisekiswa ukuthenga, ngeke kulimaze impilo yezingane, ama-phthalates angaphakathi awaqukethe i-solvent, ungakhathazeki nge-plasticizer, ukuze kulimaze impilo.
7. Izinto ze-PEVA zisetshenziswa kakhulu empilweni. Ayigcini nje ngokuba nokucaca okuphezulu, kodwa futhi nokuthambile nokuqina.
8. Impahla ye-PEVA ingamelana nezinga lokushisa eliphansi kakhulu, ngisho naku--70 degrees, futhi ifanele ukugcinwa endaweni eyiqhwa.
9.Izinto ze-PEVA zingasetshenziswa ezikhathini eziningi, hhayi amanzi kuphela, usawoti, kanye nezinhlobonhlobo zezinto.
I-10.PEVA impahla inokunamathela okuphezulu okushisayo, ingaxhunywa ngokuqinile inayiloni, i-polyester, indwangu kanye nezinye izindwangu.
11. Izinga lokushisa eliphansi elilingana lingasetshenziselwa ukusheshisa ukukhiqiza nokwenza kuzinze.
12. I-PEVA ingasetshenziswa emikhiqizweni ewubukhazikhazi kakhulu, njengokuphrinta isikrini, noma ukuphrinta kwe-offset, kodwa kucatshangwa ukuthi kufanele kusetshenziswe uyinki we-EVA.
