Iimpawu kunye nokuhlelwa kweengxowa ze-EVA kunye neebhokisi ze-EVA

I-EVA yinto yeplastiki eyenziwe nge-ethylene (E) kunye ne-vinyl acetate (VA). Umlinganiselo wezi khemikhali zimbini unokuhlengahlengiswa ukuhlangabezana neemfuno ezahlukeneyo zokusetyenziswa. Ukuphakama komxholo we-vinyl acetate (umxholo we-VA), ukuphakama kwayo kungafihli, ukuthamba kunye nokuqina kuya kuba.

Iimpawu ze-EVA kunye ne-PEVA zezi:

1. I-Biodegradable: Ayinakwenzakalisa imo engqongileyo xa ilahlwa okanye itshisiwe.

2. Ngokufana nexabiso lePVC: I-EVA ibiza kakhulu kune-PVC enetyhefu, kodwa inexabiso eliphantsi kunePVC ngaphandle kwe-phthalates.

3. I-Lightweight: Ubuninzi be-EVA buvela kwi-0.91 ukuya kwi-0.93, ngelixa i-PVC yi-1.32.

4. Ivumba: I-EVA ayinayo i-ammonia okanye ezinye izivumba eziphilayo.

5. I-Heavy metal-free: Ihambelana nemimiselo efanelekileyo yokudlala yamazwe ngamazwe (EN-71 Icandelo 3 kunye ne-ASTM-F963).

6. I-Phthalates-free: Ifanelekile kwizinto zokudlala zabantwana kwaye ayiyi kubangela umngcipheko wokukhutshwa kweplastiki.

7. Ukukhanya okuphezulu, ukuthamba kunye nokuqina: uluhlu lwesicelo lubanzi kakhulu.

8. Ukumelana nobushushu obuphantsi kakhulu (-70C): ilungele indawo ye-icing.

9. Ukumelana kwamanzi, ityuwa kunye nezinye izinto: zinokuhlala zizinzile kwinani elikhulu lezicelo.

10. Ukubambelela kobushushu obuphezulu: kunokudityaniswa ngokuqinileyo kwi-nylon, i-polyester, i-canvas kunye nezinye iingubo.

11. Ukushisa okuphantsi kwe-lamination: kunokukhawulezisa imveliso.

12. Inokushicilela isikrini kwaye iprinte i-offset: ingasetyenziselwa iimveliso ezithandekayo (kodwa kufuneka isebenzise i-inki ye-EVA).

I-EVA lining, njengoko igama libonisa, yimveliso ethile efakwe kule bhokisi ye-EVA, kwaye ke iphakheji iyafuneka ngaphandle, kwaye i-EVA lining ifakwe kule phakheji. Le phakheji ingaba yibhokisi yentsimbi yentsimbi, okanye ibhokisi yekhadibhodi emhlophe okanye ibhokisi.

Ukuhlelwa kwezinto eziphathekayo ze-EVA yokupakisha i-lining

I-EVA yokupakisha ilayini yohlulwe ikakhulu kwezi ngongoma zilandelayo:

1. Ubuninzi obuphantsi, ubuninzi obuphantsi obunobuhlobo be-EVA, abamnyama, abamhlophe kunye nombala.

2. Uxinaniso oluphezulu, uxinano oluphezulu lwe-EVA, olumnyama, olumhlophe kunye nombala.

3. I-EVA ivaliwe iseli i-28 degrees, i-33 degrees, i-38 degrees, i-42 degrees.

4. EVA iseli evulekileyo i-25 degrees, i-38 degrees
