I-PE: I-Polyethylene PE resin iyinhlayiya emhlophe engeyona enobuthi futhi engenaphunga, noma i-powder, enokubukeka okumhlophe okusansimbi nokuzizwa kwe-waxy; iyasha, inenkomba yomoya-mpilo engu-17.4% kuphela, intuthu ephansi futhi econsayo ngesikhathi somlilo, ophuzi elangabini noluhlaza okwesibhakabhaka ngaphansi.
Iphunga likapharafini; ukumuncwa kwamanzi aphansi (i-polyethyleneI-PE polyethylene PE iquketheinani elincane lamabhondi aphindwe kabili namaqembu e-ether ku-molecule, ngakho-ke ukumelana nesimo sezulu se-PE akukuhle, ilanga nemvula kuzodala ukuguga, kudinga ukwengeza ama-antioxidants, izinto zokuqinisa ukukhanya ukuze kuthuthuke Ukuzinza okushisayo kwe-polyethylene PE kugesi we-inert kuhle, futhi ukushisa kokubola kungafinyelela ku-300â „ƒ noma ngaphezulu; kepha lapho izinga lokushisa lidlula ama-50â „ƒ esimweni esishisayo, umoya-mpilo oshisayo uzobangela ukusabela okonakele, ngakho-ke kuyadingeka ukwengeza ama-antioxidants ukuwuthuthukisa. Isibonelo, i-antioxidant 1010 eyinhloko kanye ne-antioxidant eyi-168 esizayo; ukumelana nokushisa kwe-PE emoyeni akukuhle, futhi kuzothuthuka ngokwanda kwesisindo samangqamuzana ne-crystallinity; kepha ukumelana namazinga okushisa aphansi e-PE kuhle kakhulu, futhi izinga lokushisa eliphansi le-embrittlement lokushisa Ngezansi -50â „ƒ, futhi ngokwanda kwesisindo samangqamuzana, okuphansi kakhulu kungafinyelela ku -140â„ ƒ; ukuhanjiswa kokushisa kwe-PE kuphakeme, i-HDPE> LLDPE> LDPE; ukulingana kokukhula kwe-PE kukhulu, okukukhulu phakathi kwezinhlobo zepulasitiki, futhi okuphezulu kakhulu kuze kufike (20 ~ 24) × 10 -5 -5 K -1 -1, LDPE> LLDPE> HDPE.
1. I-polyethylene ephansi kakhulu LLDPE Ubuningi obuphansii-polyethylene LLDPE: Uchungechunge lwamangqamuzana lwe-polyethylene esezingeni eliphansi lunamagatsha amade futhi amafushane ne-crystallinity Low, isisindo samangqamuzana ngokuvamile singama-50,000 kuya ku-500,000, i-resin eqinile enamanzi amhlophe amhlophe, okungeyona enobuthi, iphuzu lokuthambisa eliphansi, ukuguquguquka okuhle, ukumelana nomthelela, okuhle ongaphakeme lokushisa ukumelana, futhi kungaba at -60â „ƒ Ukusebenza at -80â„ ƒ, kakhulu ukwahlukanisa kagesi.
2. I-LDPE inamandla amancane emishini, ukumelana nokushisa okuphansi, ukumelana nokuqhekeka kwengcindezi kwezemvelo, ukunamathela, nokuphrinta, futhi kudinga ukwelashwa kwendawo ukuthuthukisa ukusebenza kwayo. I-LDPE ukumuncwa kwamanzi okuphansi kakhulu, cishe akukho ukumuncwa kwamanzi, ukuqina kwamakhemikhali okuhle kakhulu, njengokuzinza kuma-acid, i-alkalis, usawoti kanye nama-solvents we-organic. Ukungena okuphezulu ku-carbon dioxide kanye nephunga elingokwemvelo, kepha ukungatholakali kahle komphefumulo wamanzi nomoya. Kulula ukusha, Ukushisa kunephunga likapharafini, kulula ukwehlisa isithunzi nokushintsha umbala ngaphansi kwesenzo selanga nokushisa.
3.Isibalo esikhulu se-polyethylene HDPE:High-ukuminyana polyethylene HDPE: It is a Milky white translucent waxy solid, the degree of branching of HDPE is the smallst, and the molecular energy is tight Stacked, so the density is high, the crystallinity is high. I-HDPE inokumelana nokushisa okuphezulu, ukumelana no-oyela, ukumelana nokuqina kwe-steam nokucindezela kokuqhekeka kwemvelo, ukufakwa kukagesi, ukumelana nomthelela nokumelana okubandayo. I-HDPE inamandla futhi Ukusebenza kokuguga kungcono kune-PP, futhi izinga lokushisa elisebenzayo liphakeme kunele-PVC ne-LDPE. I-HDPE inokumuncwa kwamanzi okuncane kakhulu, okungeyona into enobuthi, ukuzinza kwamakhemikhali okuhle kakhulu, futhi ifilimu inokungena okuphansi kumhwamuko nomoya.
