Xa kuthelekiswa ne-PET kunye ne-PP izinto, i-PP iya kuba yinto ephezulu kakhulu ekusebenzeni.
1. Umahluko kwinkcazo
I-PET(I-Polyethylene terephthalate) igama lesayensi yi-polyethylene terephthalate, eyaziwa ngokuba yi-polyester resin, i-resin material.
PP(ipolypropylene) igama lenzululwazi yipolypropylene, eyipolymer eyenziwe ngokongezwa kwepolymerization yepropylene, kwaye yiresin eyenziwe ye-thermoplastic.
2.Ukusuka kwiimpawu zomahluko
(1) PET
①PET lubisi olumhlophe okanye olutyheli olukhaphukhaphu lwepolymer oluphezulu olunomphezulu ogudileyo nobengezelayo.
I-②PET imathiriyeli inokumelana nokudinwa okuhle, ukuxhathisa kwe-abrasion kunye nokuzinza komda, ukunxiba okuphantsi kunye nobunzima obuphezulu, amandla okugoba e-200MPa, kunye ne-elastic modulus ye-4000MPa.
③ Izinto ze-PET zinomsebenzi obalaseleyo wokuchasana nobushushu obuphezulu kwaye obuphantsi, obunokusetyenziswa ixesha elide kuluhlu lobushushu be-120 °C, kwaye inokumelana nobushushu obuphezulu be-150 °C ukusetyenziswa kwexesha elifutshane kunye nobushushu obuphantsi kwe -70 ° C. C.
④ I-Ethylene glycol esetyenziselwa ukuveliswa kwe-PET inexabiso eliphantsi kunye nokusebenza kweendleko eziphezulu.
⑤Impahla ye-PET ayinayo inetyhefu, inozinzo olufanelekileyo malunga neekhemikhali, kwaye ixhathisa i-acids ebuthakathaka kunye ne-solvents ye-organic, kodwa ayinakumelana nokucwiliswa emanzini ashushu kunye ne-alkali.
(2) PP
I-①PP yimathiriyeli emhlophe ene-waxy enenkangeleko ecacileyo kunye nekhaphukhaphu.Lolona hlobo lukhaphukhaphu lweresin ezisetyenziswa ngokuqhelekileyo.
Izinto ze-②PP zineempawu ezibalaseleyo zoomatshini kunye nokumelana nobushushu, kwaye ubushushu bokusetyenziswa okuqhubekayo bunokufikelela kwi-110-120 ° C.
③ Izinto zePP zinozinzo olugqwesileyo lweekhemikhali kwaye alusebenzisani neekhemikhali ezininzi ngaphandle kwee-oxidants ezinamandla.
④Impahla yePP inobushushu obuphezulu bokunyibilika kunye namandla okuqina, kwaye ukubonakala kwefilimu kuphezulu.
I-⑤PP imathiriyeli ine-insulation egqwesileyo yombane, kodwa kulula ukuguga kwaye inamandla empembelelo embi kwiqondo lobushushu eliphantsi.
3. Umahluko ekusebenziseni
I-PET isetyenziswa ngokubanzi, njengokujikeleza kwi-polyester fiber, oko kukuthi, i-polyester;njengeplastiki, inokuvuthelwa kwiibhotile ezahlukeneyo;njengamacandelo ombane, iibheringi, iigiya, njl.
Izinto zePP zisetyenziswa ngokubanzi kwimveliso yesitofuiimveliso zokubumba, iifilimu, iipayipi, iipleyiti, iifayili, iingubo, njl., kunye nezixhobo zendlu, i-steam, ikhemikhali, ukwakhiwa, imboni yokukhanya kunye nezinye iindawo.
