Iwe unofanirwa kujairana nekaviri-layer girazi.Icho chinhu chakajairika uye chinowanzoshandiswa mukombe chigadzirwa muhupenyu hwedu.Unoziva here nheyo yekugadzira yegirazi-layer girazi?Tevere, ngatinzwisisei musimboti wembiri-layer girazi blow molding:
1. Girazi rinofuridzwa nemaoko maviri-layer
Kufuridza nemaoko inzira yakaoma.Kutanga, iwe unofanirwa kunyudza imwe mugumo wemhangura kana iron blow tube kuti utore girazi rinyunguduke.Iwe unofanirwa kuridza kune imwe mugumo wechubhu yekuvhuvhuta kuti ufuridze mukati mechimiro chatinoda, wobva washandisa chigero kuti udzikise.Up.Mukuita kuvhuvhuta nemaoko maviri-layer girazi, ruoko rwemushandisi nderwekuenderera mberi nekutenderedza chubhu inovhuvhuta kuti ive nechokwadi chekuti mhinduro yegirazi haizorasikike.Kune rumwe rutivi, inzira yekushandisa viscosity yegirazi kuiumba kuva chimiro chatinoda.Nenzira iyi, girazi rinoputika rinoputika rinogona kukwana kuitira kurongeka uye kushanda pamwe chete.Izvo zvinofanirwa kunzwisiswa kuti ukuru uye ukobvu hwekaviri-layer girazi zvese zvinotarirwa nehuwandu hwemhepo inoputika.
2. Molded blow molding
Kutanga shandisa mhangura kana simbi kugadzira hollow modhi, wozoshandisa blow tube kunyudza girazi kunyunguduka, isa mhinduro yegirazi muforoma uye wotanga kuvhuvhuta kusvika mhinduro yegirazi yazara nemadziro emukati emuenzaniso uye wobvisa mold.Nenzira iyi, maviri-layer girazi makapu emhando dzakasiyana-siyana anogona kugadzirwa, izvo zvinowedzera hunyanzvi kune chimiro chemuviri wekombe.
Zvino kana vanhu vakasarudza girazi rine mativi maviri, havangove nezvinodiwa zvebasa rayo chete asiwo pakuonekwa kwaro, saka tinogona kuzadzisa zvinodiwa neruzhinji nekusarudza nzira yekufuridza inonzwisisika.
