Mibvunzo Inowanzo bvunzwa
Mubvunzo 1: Ungasarudza sei zvinhu zvechikafu chakaomeswa nechando?
Mhinduro: Mapurasitiki anochinjika anoshandiswa mukugadzira chikafu chakaomeswa nechando akakamurwa kuita zvikamu zvitatu: chikamu chekutanga mabhegi ane jira rimwe chete, akadai semabhegi ePE, ane simba rakashata rekudzivirira uye anowanzo shandiswa pakurongedza muriwo, nezvimwewo; chikamu chechipiri mabhegi epurasitiki anochinjika, akadai semabhegi eOPP //PE (asina kunaka), NYLON//PE (PA//PE iri nani), nezvimwewo, ane hunhu hwakanaka hunodzivirira hunyoro, hunodzivirira kutonhora, uye hunodzivirira kuboorwa; chikamu chechitatu mabhegi epurasitiki akapfava ane jira rakawanda, anosanganisa zvinhu zvisina kugadzirwa nemabasa akasiyana, Semuenzaniso, PA, PE, PP, PET, nezvimwewo zvinonyungudutswa uye zvinoburitswa zvakasiyana, uye zvinosanganiswa pamusoro wese wekufa kuburikidza nekuumbwa kwemhepo nekutonhodza. Rudzi rwechipiri ndirwo runonyanya kushandiswa pari zvino.
Mubvunzo 2: Rudzii rwezvinhu zviri nani pakugadzira mabisikiti?
Mhinduro: OPP/CPP kana OPP/VMCPP inowanzo shandiswa pamabhisikiti, uye KOP/CPP kana KOP/VMCPP inogona kushandiswa kuchengetedza kunaka kuri nani.
Mubvunzo 3: Ndinoda firimu rinoonekera rine zvinhu zviri nani zvekudzivirira, saka ndeipi ine zvinhu zviri nani zvekudzivirira, BOPP/CPP kana PET/CPP?
Mhinduro: Kuvhara kweK kune hunhu hwakanaka hwekudzivirira, asi kujeka kwacho hakuna kunaka sekwePET/CPP.
