Minchina iibelesyegwa loko iibikkilizya minchina yamapulasitiki, PLC Pressure Thermoforming Machine, Muncini wakupyasya nkomeki yapulasitiki yamaanzi, azimwi. Ino mapulasitiki aali buti ngaakonzya kubelesegwa? Aaya ngamapulasitiki aabelesyegwa kapati.
Misyobo iili 7 yamapulasitiki
A. Ma polyester naa PET
Ma polyesters naakuti PET (Polyethylene terephthalate) nchintu chisalala, chiyumu, chiyumu chili aanguzu zyakukwabilila muya akutontola. Chiindi chiingi chibelesyegwa kubamba muya uutegwa carbon dioxide (uutegwa carbonation) mumabbodela azyakunywa zitontola. Ikubelesegwa kwayo akwalo kubikkilizya filimu, mapepa, ntambo, matreyi, zitondezyo, zizwaato, antoomwe akukwabilila waya.
B. CPET
CPET (Crystallized Polyethylene Terephthalate) pepa lyakabambwa kuzwa ku PET resin yakabambwa kuti iyungizye kuliyumya kwakupya. CPET ilizyibidwe akukazya kupya kupati, kanjikanji aakati ka -40 ~ 200 ℃, nchintu chibotu chakupanga mabbokesi aazyakulya, mabbokesi aazyakulya zyamasikati, zibelesyo. Bubotu bwa CPET: ilakonzya kubelesegwa lubo kumbali aamugwagwa mpawo ilakonzya kunjila mubbokesi lyakubelesya lubo nikwakasanzyigwa; Nchintu chili kabotu kubelesegwa mu microwave amufiriji; Alimwi eezyi zibelesyo zyakulya zilakonzya kubelesegwa lubo.
C. Vinyl naa PVC
Vinyl naa PVC (Polyvinyl chloride) nchintu chidumide kapati. Chili abube bulikozyene a PET kutondezya kusalala kubotu, kukaka kutyolwa, akukakatila. Chiindi chiingi chipangwa mumapepa aayo aazoopangwa kuba zintu zyiingi. Mbuli filimu, vinyl ilayoya mweelwe weelede kupa kuti ibe kabotu mukupakila nyama mpya.
D. PP
PP (polypropylene) ilakonzya kukazya misamu iikola kapati alimwi ilabelesyegwa mukupanga nkomeki zyakubikkila zintu, nkomeki zyamicelo alimwi aciyobwedo cazyakulya.
E.PS
PS (polystyrene) yakali chintu chipati chakupanga mulilo myaaka makumi obile yakainda. Ilakonzya kubelesegwa kabotu loko mpawo ilakonzya kukkalwa kabotu pesi ilakonzya kukazyigwa aamaanzi. Ikubelesegwa kwawo mazubaano kubikkilizya azyakulya azyabusilisi, zibelesyo zyamuŋanda, zisobano, zyakukkala, zitondezyo zyakwaambilizya, antoomwe amafiliji.
F.BOPS
BOPS (Biaxially oriented polystyrene) nchintu chibelesyegwa mumakwebo, chili abubotu bwakukonzya kweendelana azintu zipona, tachikwe bbivwe, chili antangalala, chili abulemu bupati alimwi chili amali masyoonto. Alimwi nchintu chipya chitanyonyooni busena mukupakila chakulya.
