Uma kuziwa kumalebula azinamathiselayo, wonke umuntu kufanele aqale acabange nge-PET ne-PVC, kodwa kungakanani okwaziyo ngamalebula enziwe nge-PET ne-PVC? Namuhla, ake ngikubonise:
Umehluko 1
Umumo we-raw material uhlukile:
I-PVC, okungukuthi, i-polyvinyl chloride, umbala wokuqala ubonakala ngokuphuzi kancane futhi ucwebezelayo.
I-PET, okungukuthi, i-polyethylene terephthalate, inokucaca okuhle kakhulu.
Amandla wezinto ezingavuthiwe ahlukile:
I-PVC, okungukuthi, i-polyvinyl chloride, inokucaca okungcono kune-high-pressure polyethylene ne-polystyrene, kodwa kubi kakhulu kune-polyethylene. Ihlukaniswe yaba i-polyvinyl chloride ethambile futhi eqinile ngokuya ngenani elihlukile lezishintshi ezisetshenzisiwe. Umkhiqizo othambile uthambile futhi uqinile, futhi uzwakala unamathela. Amandla omkhiqizo oqinile aphakeme kunalawo e-polyethylene ephezulu yokucindezela okuphansi, kodwa aphansi kune-polypropylene, futhi umhlophe uzokwenzeka ekugobeni.
I-PET, okungukuthi, i-polyethylene terephthalate, inamandla okucindezela angcono kanye ne-ductility kune-polyethylene ne-polyvinyl chloride, futhi akulula ukuphuka.
Ukusetshenziswa kwezinto zokusetshenziswa kuhlukile:
I-PVC, okungukuthi, imikhiqizo evamile ye-polyvinyl chloride: amabhodi, amapayipi, izicathulo zezicathulo, amathoyizi, amafasitela neminyango, izikhumba zekhebula, izinto zokubhala, njll.
I-PET, okungukuthi, ukusetshenziswa okuvamile kwe-polyethylene terephthalate: kuvame ukubonakala kumalebula womkhiqizo adinga amanzi aphezulu, ukumelana ne-alkali, ukumelana namakhemikhali, ukumelana nokushisa nezinye izakhiwo, ezisetshenziselwa izinto zokugezela, imikhiqizo yokunakekelwa kwesikhumba, indlu ehlukahlukene. izinto zikagesi, imikhiqizo yemishini, njll.

1. I-PVC ayisebenzi kabusha, kodwa i-PET igaywa kabusha;
2. Uma usebenzisa amabhodlela e-PET namalebula e-PVC, udinga ukususa amalebula e-PVC lapho ugaywa kabusha amabhodlela; kuyilapho amalebula e-PET engadingi ukususwa;
3. I-PET inezici ezinhle kakhulu ze-dielectric, ene-anti-fouling enhle, i-anti-scratch, ukumelana nokushisa okuphezulu nezinye izakhiwo;
4. I-PVC ne-PET zinezakhiwo ezifanayo. Inokuguquguquka okungcono nomuzwa othambile kune-PET, kodwa i-PVC inokuwohloka okubi kakhulu futhi inomthelela omubi ekuvikelweni kwemvelo.
5. I-PET ivame ukuba ne-PET emhlophe noma i-PET ebonakalayo, futhi ingenziwa futhi ibe indawo yegolide noma yesiliva, ebukeka kahle kakhulu.
6. Amalebula e-PET anezakhiwo ezinhle zemishini, ukumelana nomthelela oqinile, ukumelana nowoyela kanye nokumelana namafutha. Ukumelana nezinga lokushisa eliphezulu neliphansi nakho kunamandla kunamapulasitiki amaningi, ngakho-ke izitika zasekhishini esivame ukuzibona zenziwe nge-PET + aluminium foil.
7. Izinto ze-PET zinokucaca okuhle nokuthambile okuhle ngaphansi kuka-25u. Isetshenziselwa ikakhulukazi amabhayisikili nezithuthuthu namalebula encazelo yomkhiqizo kagesi. I-White PET isetshenziswa kakhulu kumalebula ebhethri omakhalekhukhwini, njll.
8. Umehluko omkhulu ovela ku-PVC ukuthi unokunganzi kahle kwe-thermal futhi kulula ukuguga ukukhanya, ukushisa nomoya-mpilo. Ngaphezu kwalokho, izithasiselo ezinobuthi eziningi zivame ukungezwa phakathi nenqubo yokukhiqiza ye-PVC.
Umehluko 3
I-PET: iqinile, iqinile, inamandla amakhulu, indawo ekhanyayo, amashidi anobungani bemvelo, asobala nanemibala eminingi. Ububi ukuthi i-PET high-frequency heat bonding inzima kakhulu futhi intengo ibiza kakhulu kune-PVC. Lokhu okubalulekile kuvame ukuthathelwa indawo yi-PVC ngabasebenzisi abadinga imikhiqizo emihle nokuvikelwa kwemvelo. Izinto ze-PET zivame ukusetshenziselwa ukwenza amabhodlela epulasitiki, amabhokisi okupakisha okudla, njll.
I-PVC: Indwangu yamabhamuza evame ukusetshenziswa ethambile, eqinile, nepulasitiki. Ingenziwa ibe sobala futhi ibe nemibala ehlukahlukene. I-PVC esobala ivamise ukusetshenziselwa ukupakisha izinto zikagesi, izimonyo, amathoyizi, izipho, neminye imikhiqizo.
