Kana zvasvika kune anozvinamira mavara, munhu wese anofanira kutanga afunga nezvePET nePVC, asi zvakawanda sei zvaunoziva nezvemavara akagadzirwa nePET nePVC? Nhasi, rega ndikuratidze:
Musiyano 1
Iyo raw material shape yakasiyana:
PVC, kureva, polyvinyl chloride, iyo yepakutanga ruvara rune yellowish yakajeka uye inopenya.
PET, kureva, polyethylene terephthalate, ine kujekesa kwakanaka kwazvo.
Kusimba kweiyo raw materials kwakasiyana:
PVC, kureva, polyvinyl chloride, ine kujeka kuri nani pane yakakwirira-kumanikidza polyethylene uye polystyrene, asi yakaipisisa kupfuura polyethylene. Yakakamurwa kuita yakapfava uye yakaoma polyvinyl chloride zvinoenderana nehuwandu hwakasiyana hwema modifiers anoshandiswa. Chigadzirwa chakapfava chakapfava uye chakaoma, uye chinonzwa chakanamira. Kusimba kwechigadzirwa chakaoma chakakwirira kudarika che-low-density high-pressure polyethylene, asi yakaderera pane iyo ye polypropylene, uye kuchena kuchaitika pakubhenda.
PET, kureva, polyethylene terephthalate, ine zviri nani kudzvinyirira simba uye ductility kupfuura polyethylene uye polyvinyl chloride, uye haisi nyore kuputsika.
Kushandiswa kwezvinhu zvakasvibirira kwakasiyana:
PVC, kureva, izvo zvakajairika zvigadzirwa zve polyvinyl chloride: mapuranga, pombi, bhutsu masosi, matoyi, mahwindo nemagonhi, matehwe etambo, stationery, nezvimwe.
PET, ndiko kuti, kushandiswa kwakajairika kwe polyethylene terephthalate: inowanzoonekwa mune zvinyorwa zvechigadzirwa zvinoda kukwira kwemvura, alkali-resistant, chemical-resistant, heat-resistant uye zvimwe zvivakwa, zvinoshandiswa midziyo yekugezera, ganda rekuchengetedza zvigadzirwa, dzakasiyana siyana dzemumba. midziyo, michina zvigadzirwa, nezvimwe.
Musiyano 2
1. PVC haigoni kushandiswa zvakare, asi PET inoshandiswa zvakare;
2. Kana ukashandisa mabhodhoro ePET uye mavara ePVC, unoda kubvisa zvinyorwa zvePVC paunenge uchidzokorora mabhodhoro; nepo PET zvinyorwa zvisingadi kubviswa;
3. PET ine yakanakisa dielectric properties, ine yakanaka anti-fouling, anti-scratch, yakakwirira tembiricha kuramba uye zvimwe zvinhu;
4. PVC nePET vane zvinhu zvakafanana. Iyo ine zvirinani kuchinjika uye yakapfava kunzwa kupfuura PET, asi PVC ine hurombo kuderera uye ine kukanganisa kwakashata pakuchengetedzwa kwezvakatipoteredza.
5. PET inowanzova nePET chena kana PET yakajeka, uye inogonawo kugadzirwa kuva goridhe kana sirivheri pamusoro, iyo inotaridzika yakanaka kwazvo.
6. PET mabhii ane yakanaka mechanical properties, yakasimba kukanganisa kupikisa, mafuta anopikisa uye mafuta kuramba. Yepamusoro uye yakaderera tembiricha kuramba zvakare yakasimba kupfuura akawanda epurasitiki, saka zvimiti zvekicheni zvatinowanzoona zvakagadzirwa nePET + aluminium foil.
7. PET zvinhu zvine kujeka kwakanaka uye kupfava kwakanaka pazasi 25u. Inonyanya kushandiswa bhasikoro uye midhudhudhu decals uye mamwe magetsi chigadzirwa tsananguro zvinyorwa. White PET inonyanya kushandiswa mune nharembozha bhatiri mavara, nezvimwe.
8. Mhedzisiro huru kubva kuPVC ndeyokuti ine urombo husina kugadzikana uye inokwegura nyore nyore nechiedza, kupisa uye oksijeni. Uye zvakare, akawanda ane muchetura ekuwedzera anowanzo kuwedzerwa panguva yePVC kugadzira maitiro.
Musiyano 3
PET: yakaoma, yakaoma, yakasimba simba, inopenya pamusoro, ine hushamwari kwezvakatipoteredza, yakajeka uye yakawanda-mavara mapepa. Izvo zvakashata ndezvekuti PET yakakwirira-frequency kupisa bonding yakanyanya kuoma uye mutengo unodhura zvakanyanya kupfuura PVC. Ichi chinyorwa chinowanzotsiviwa nePVC nevashandisi vanoda zvigadzirwa zvakanaka uye kuchengetedzwa kwezvakatipoteredza. PET zvinhu zvinowanzo shandiswa kugadzira mabhodhoro epurasitiki, mabhokisi ekurongedza chikafu, nezvimwe.
PVC: Chinhu chinowanzo shandiswa blister chakapfava, chakasimba, uye chepurasitiki. Inogona kuitwa yakajeka uye mumarudzi akasiyana-siyana. Transparent PVC inowanzo shandiswa kurongedza zvemagetsi, zvekuzora, matoyi, zvipo, uye zvimwe zvigadzirwa.
