Xa kuziwa kwiileyibhile ezincamathelayo, wonke umntu kufuneka aqale acinge ngePET kunye nePVC, kodwa wazi kangakanani malunga neelebhile ezenziwe ngePET kunye nePVC? Namhlanje, mandikubonise:
Umahluko 1
Ubume bemali ekrwada yahlukile:
I-PVC, oko kukuthi, i-polyvinyl chloride, umbala wokuqala unombala obomvu ocacileyo kunye nokukhanya.
I-PET, oko kukuthi, i-polyethylene terephthalate, inokucaca kakuhle kakhulu.
Ukomelela kwemathiriyeli ekrwada kwahlukile:
I-PVC, oko kukuthi, i-polyvinyl chloride, inokucaca okungcono kune-polyethylene ephezulu kunye ne-polystyrene, kodwa imbi kune-polyethylene. Ikwahlulwe ibe yi-polyvinyl chloride ethambileyo kwaye eqinile ngokwexabiso elahlukileyo leemodyuli ezisetyenzisiweyo. Imveliso ethambileyo ithambile kwaye yomelele, kwaye ivakala incangathi. Amandla emveliso enzima iphezulu kune-low-density high-pressure polyethylene, kodwa iphantsi kune-polypropylene, kunye nomhlophe kuya kwenzeka kwi-bend.
I-PET, oko kukuthi, i-polyethylene terephthalate, inamandla angcono kunye ne-ductility kune-polyethylene kunye ne-polyvinyl chloride, kwaye akulula ukuphuka.
Ukusetyenziswa kwemathiriyeli ekrwada kwahlukile:
I-PVC, oko kukuthi, iimveliso eziqhelekileyo ze-polyvinyl chloride: iibhodi, iibhobho, izicathulo zezicathulo, amathoyizi, iifestile kunye neengcango, izikhumba zekhebula, izinto zokubhala, njl.
I-PET, oko kukuthi, ukusetyenziswa okuqhelekileyo kwe-polyethylene terephthalate: idla ngokubonwa kwiileyibhile zemveliso ezifuna ukukhuseleka kwamanzi, i-alkali-resistant, i-chemical-resistant, i-heat-resistant kunye nezinye iipropati, ezisetyenziselwa izixhobo zokuhlambela, iimveliso zokunakekelwa kwesikhumba, izindlu ezahlukeneyo. izixhobo zombane, iimveliso zoomatshini, njl.
Umahluko 2
1. I-PVC ayinakuphinda isetyenziswe, kodwa i-PET iphinda isetyenziswe;
2. Ukuba usebenzisa iibhotile ze-PET kunye neelebhile ze-PVC, kufuneka ususe iilebhile ze-PVC xa uhlaziywa iibhotile; ngelixa iileyibhile zePET kungafuneki ukuba zisuswe;
3. I-PET ineempawu ezibalaseleyo ze-dielectric, kunye ne-anti-fouling efanelekileyo, i-anti-scratch, ukumelana nokushisa okuphezulu kunye nezinye iimpawu;
4. I-PVC kunye ne-PET zineempawu ezifanayo. Inokuguquguquka okungcono kunye nokuziva okuthambileyo kune-PET, kodwa i-PVC inokonakala okuphantsi kwaye inefuthe elibi ekukhuselweni kwendalo.
5. I-PET idla ngokuba ne-PET emhlophe okanye i-PET ecacileyo, kwaye ingenziwa kwakhona kwindawo yegolide okanye yesilivere, ekhangeleka kakhulu.
I-6. Iilebhile ze-PET zineempawu ezintle zoomatshini, ukuchasana kwempembelelo enamandla, ukunyanzeliswa kweoli kunye nokuxhatshazwa kwamafutha. Ukumelana nobushushu obuphezulu kunye nobuphantsi bunamandla kuneeplastiki ezininzi, ngoko ke izitikha zasekhitshini esihlala sizibona zenziwe nge-PET + ngefoyile yealuminiyam.
7. Izinto ze-PET zinokucaca kakuhle kunye nokuthamba okulungileyo ngaphantsi kwe-25u. Isetyenziswa ikakhulu kwiibhayisikile kunye needecals zesithuthuthu kunye neeleyibhile zenkcazo yemveliso yombane. I-PET emhlophe isetyenziswa ikakhulu kwiilebhile zebhetri yeselula, njl.
8. Umahluko omkhulu ovela kwi-PVC kukuba unozinzo olubi lwe-thermal kwaye luguga ngokulula ngokukhanya, ukushisa kunye ne-oxygen. Ukongeza, izongezo ezinetyhefu zihlala zongezwa ngexesha lenkqubo yokuvelisa iPVC.

I-PET: ilukhuni, ilukhuni, inamandla amakhulu, indawo eqaqambileyo, ihambelana nokusingqongileyo, i-transparent and multi-color sheet. Ububi kukuba i-PET i-high-frequency heat bonding inzima kakhulu kwaye ixabiso libiza kakhulu kunePVC. Esi sixhobo sihlala sitshintshwa yiPVC ngabasebenzisi abafuna iimveliso ezilungileyo kunye nokukhuselwa kwendalo. Izinto ze-PET zisetyenziswa ngokubanzi ukwenza iibhotile zeplastiki, iibhokisi zokupakisha ukutya, njl.
I-PVC: Isixhobo se-blister esisetyenziswa ngokuqhelekileyo esithambileyo, esiqinileyo, kunye neplastiki. Ingenziwa ecacileyo kunye nemibala eyahlukeneyo. I-PVC ecacileyo ihlala isetyenziselwa ukupakisha izinto zombane, izithambiso, iithoyi, izipho, kunye nezinye iimveliso.
