Nyika yoonse - PET yakusaanguna: Polymer Iinda kubota yakubelesya munzila ziindene-indene
Zibeela Zipati Zyakubelesya
PET ilabelesyegwa kapati mumakwebo aakupaka, ikapati mumabbodela aazyakunywa. Bube bwayo bubotu bwakukwabilila muya mubotu, buteteete, a carbon dioxide bupa kuti ibe chintu chibotu chakukwabilila bubotu bwazyakunywa zijisi carbon dioxide, ma juice, amaanzi. Kusalala kwa PET kupa kuti chintu chiboneke kabotu mukati, mpawo chisumpula kusambalwa kwacho. Kuyungizya waawo, mabbodela aa PET taali abulemu pe, taakonzyi kutyompokelwa, alimwi taakatazyi kujata, aboobo alagwasya basikuula. Mukubamba chakulya, PET ibelesyegwa mbuli zibelesyo zyakuyobweda zyakulya zyaandeene, kupa lukwabililo kuzwa kukunyonyooka akubamba bubotu abubotu bwazintu zilimukati.
Mumakwebo aazisani, PET nchintu chibelesegwa kapati mukupanga zintu zyakupanga. Insinga eezyi, zizyibidwe kuti polyester, zilaanguzu zibotu, tazikonzyi kuvwundauka, mpawo zilakonzya kuyuma chakufwambaana. Zilabelesyegwa kapati mukupanga zizwaato, zyakusama zyaaŋanda, antoomwe azyakusama zyamafakitali. PET - ntambo zya polyester zilakonzya kusanganyigwa antambo zyacilengwaleza kuchitila kuti zintu zizumanane kubeleka kabotu. Mukuyungizya, nsinga zilakonzya kudayigwa chakufwambaana, kupa kuti kube mibala myiingi anzila zyakupanga zintu kuti zyeendelane aziyandikana zyakusama azyakupanga.
Inkamu yamagesi ayalo ilagwasyigwa azintu zilibedelede zya PET. Ibelesyegwa mukupanga mafilimu aakukwabilila magesi akaambo kakuti ilakonzya kukwabilila magesi. Mafilimu aa PET ngaateteete, alakonzya kuzungaana, alimwi alakonzya kukkalwa kabotu, aboobo alakonzya kubelesyegwa muzibeela zyamagesi mbuli capacitors, transformers, ama printed circuit boards. Mukuyungizya, PET ilabelesyegwa mukupanga zipekupeku zya LCD mbuli chintu chakubelesya, kupa busena buteteete alimwi butazungaani bwazibeela zyakutondezya.
PET alimwi ilabelesyegwa mumakwebo aakupanga myootokala. Chibelesyegwa kupanga zibelesyo zyamukati, zilimbuli milyango azivwunisyo zyazyuuno, akaambo kakuboneka kabotu kwacho akukazya kubola. Ma PET - based composites abelesyegwa mukupanga zibeela zya myootokala kuchitila kuti kuchesegwe kulema akusumpula mafuta. Kwiindawo, PET ilabelesyegwa mukupanga zibeela zya injini azibeela zya mafuta nkaambo tiikonzyi kupya amisamu.

Mubufwaafwi
I Global - Premier PET yesu ilajanika munzila zisiyene, kubikkilizya ama pellets, mafilimu, antoomwe a fibers, kuti izuzikizye ziyandikana zyamakkampani aasiyene. Musyobo umwi aumwi wa PET ulasunkwa loko kuchitila kuti ube abube butazungaani, mbuli kuyuma, busena bwakunyenguluka, kusima, akusalala. Tulapa nzila zipangidwe kweelana azintu nzyobayanda basikuula besu. Nikuba kuti uli kkampani iibamba zintu muEzhiya, kkampani iipanga zisani muYulopu, kkampani yamagesi muNorth America, naakuti kkampani iisambala myootokala muAustralia, Global - Premier PET yesu ninzila iisyomeka alimwi yabubotu bwa polymer njokonzya kusyoma kuti iyungizye bubotu bwazintu zyako.
