Ambiri ntchito makina otentha matenthedwe mongamakina opangira pulasitiki,PLC Pressure Thermoforming Machine,Hydraulic Servo Plastic Cup Thermoforming Machine , etc. Ndi mapulasitiki otani omwe ali oyenera? Nazi zida zapulasitiki zomwe zimagwiritsidwa ntchito kwambiri.
Pafupifupi Mitundu 7 yapulasitiki
A. Polyesters kapena PET
Polyester kapena PET (Polyethylene terephthalate) ndi polima yowoneka bwino, yolimba, yokhazikika yokhala ndi mpweya wapadera komanso zotchinga chinyezi. Nthawi zambiri amagwiritsidwa ntchito kukhala ndi carbon dioxide (alias carbonation) m'mabotolo a zakumwa zozizilitsa kukhosi. Ntchito zake zimaphatikizaponso filimu, mapepala, fiber, ma trays, zowonetsera, zovala, ndi kutsekereza waya.
B. CPET
CPET (Crystallized Polyethylene Terephthalate) pepala amapangidwa kuchokera PET utomoni kuti crystallized kuwonjezera kutentha kulolerana. CPET imadziwika ndi kukana kutentha kwambiri, nthawi zambiri pakati pa -40 ~ 200 ℃, ndi zinthu zabwino zopangira ma tray ophikidwa a pulasitiki, mabokosi amasana, zotengera. Ubwino wa CPET: ndi curbside recyclable ndipo imatha kulowa mu bin yobwezeretsanso ikatsukidwa; Ndi bwino kugwiritsidwa ntchito mu microwave ndi mufiriji; Ndipo zotengera zakudyazi zitha kugwiritsidwanso ntchito.
C. Vinyl kapena PVC
Vinyl kapena PVC (Polyvinyl chloride) ndi chimodzi mwazinthu zodziwika bwino za thermoplastic. Ili ndi zinthu zofanana kwambiri ndi PET zomwe zikuwonetsa kumveka bwino, kukana kuphulika, ndi kukakamira.Kawirikawiri amapangidwa m'mapepala omwe pambuyo pake amapangidwa kukhala zinthu zambiri. Monga filimu, vinyl imapuma mokwanira kuti ikhale yabwino kunyamula nyama zatsopano.
D. PP
PP (polypropylene) imakhala ndi kutentha kwambiri kwa mankhwala ndipo imagwiritsidwa ntchito popanga kapu yonyamula, thireyi ya zipatso ndi chidebe cha chakudya.
E.PS
PS (polystyrene) inali yolamulira thermoforming zaka 20 zapitazo. Ili ndi processability yabwino kwambiri komanso kukhazikika kwazithunzi koma kukana zosungunulira zochepa. Zomwe zimagwiritsidwa ntchito masiku ano zimaphatikizapo zakudya ndi zopakira zamankhwala, ziwiya zapanyumba, zoseweretsa, mipando, zowonetsera zotsatsa, ndi zomangira mafiriji.
F.BOPS
BOPS (Biaxially oriented polystyrene) ndi zinthu zopangira malonda, zomwe zimakhala ndi zabwino za biocompatibility, zopanda poizoni, zowonekera, zopepuka komanso zotsika mtengo. Ndichinthu chatsopano chothandizira chilengedwe popaka chakudya.
