Isantya esiphezulu Cast Cast Breathable Film Line

Umgca wefilimu ophefumulayo unenkqubo efanayo yokukhupha njengeminye imigca yefilimu ephosiweyo, kodwa ixhotyiswe ngeyunithi ye-MDO (i-machine direction orientation).Izaliswe nge appr.Ipesenti ye-50 yepesenti yeCaCo3, ifilimu yoluliwe yiyunithi ye-MDO ukwenza iipores ezincinci ngaphakathi.Ezo pores ezinoxinano oluphezulu kwifilimu zivumela igesi okanye umphunga wamanzi ukuba usasaze kodwa umise ukuhamba kolwelo.Ke ifumana igama njenge "ifilimu ephefumlayo".Iimpawu zayo ezibalaseleyo azinakufumaneka kuphela "kwi-breathable", kodwa nakwi-textile-like feeling yesandla, iyenza ibe yi-backsheet efanelekileyo ye-diaper kunye ne-napkin yangasese.
Ezona ndawo zisetyenziswayo kwiifilimu zeplastiki eziphefumlayo zibandakanya iimveliso zococeko lobuqu, iimveliso zokhuseleko lwezonyango (ezinje ngoomatrasi zonyango, iimpahla ezikhuselayo, iigawuni zotyando, amashiti otyando, iicompresses ezishushu, iipillowcases zonyango, njl. .
Umgca wokuvelisa ifilimu ophefumlayo kaWellson usebenzisa inkqubo ekhethekileyo yolawulo lwe-bimetallic screw extrusion.Ngokulungisa uyilo lomjelo wokuhamba, unokuphucula ngcono izinga lokunyibilika kunye nefuthe leplastiki lezinto eziluhlaza, kwaye ihlangabezane neemfuno ezikhethekileyo ze-extrusion ye-resin ekrwada.Ngokwamkela uyilo lwembaleki yodidi lwe-pendant ye-pendant-hlobo lwembaleki, intloko yokufa ezenzekelayo ngokugqibeleleyo kunye neyona ndlela ichanekileyo yokubona ubukhulu obuzenzekelayo kunye nenkqubo yokulawula inokulandelela ngempumelelo ngakumbi kwaye ilawule ukufana okuthe tye nokuthe nkqo kwefilimu, ngaloo ndlela iqinisekisa umgangatho wayo ophezulu. .Oku kubalulekile ukuqinisekisa ukusetyenzwa okulandelayo kunye nokwelula okungenangxaki kwefilimu.
