Uyini umehluko phakathi kwezinto zokufakwa kwamakhebula i-PE, i-PVC, ne-XLPE?

Njengamanje, izinto zokufakwa kwamakhebula ezisetshenziswa ekukhiqizweni kwamakhebula zihlukaniswe ngokwezigaba ezintathu: i-PE, i-PVC, ne-XLPE.Okulandelayo kwethula umehluko phakathi kwezinto zokuvikela i-PE, i-PVC, ne-XLPE ezisetshenziswa kumakhebuli.

Ei-xplanation yokuhlukaniswa nezici zezinto zokuvikela ikhebula

I-PVC: I-Polyvinyl chloride, i-polymer eyakhiwe yi-polymerization yamahhala ye-vinyl chloride monomers ngaphansi kwezimo ezithile.Inezici zokuzinza, ukumelana ne-asidi, ukumelana ne-alkali, ukumelana nokugqwala, nokumelana nokuguga, futhi isetshenziswa kabanzi ezintweni zokwakha, izidingo zansuku zonke, amapayipi namapayipi, izintambo nezintambo, nezinto zokuvala.Ihlukaniswe yaba izinto ezithambile neziqinile: ezithambile zisetshenziselwa ikakhulukazi ukwenza izinto zokupakisha, amafilimu ezolimo, njll., futhi zisetshenziswa kabanzi ekwenzeni izingqimba zokufakwa kwezintambo zocingo nezintambo, njengezintambo zamandla ezivalekile ze-polyvinyl chloride;kuyilapho eziqinile ngokuvamile zisetshenziselwa ukwenza amapayipi namapuleti.Isici esikhulu kunazo zonke sezinto ezibonakalayo ze-polyvinyl chloride yi-flame retardancy, ngakho-ke isetshenziswa kabanzi emkhakheni wokuvimbela umlilo futhi ingenye yezinto ezivame ukusetshenziswa kakhulu zokuvikela amalangabi nezintambo nezintambo ezingashi.

I-PE: I-Polyethylene iyi-resin ye-thermoplastic eyenziwe nge-polymerization ye-ethylene.Ayinabuthi futhi ayinabungozi, inokumelana nezinga lokushisa eliphansi kakhulu, futhi ingamelana nokuguguleka kwama-asidi amaningi nama-alkali, futhi inokusebenza okuhle kakhulu kokufakwa kukagesi.Ngesikhathi esifanayo, ngenxa yokuthi i-polyethylene inezici zokungeyona i-polarity, inezici zokulahlekelwa okuphansi kanye ne-conductivity ephezulu, ngakho-ke ngokuvamile isetshenziswa njengento yokufakelwa kwezintambo eziphezulu ze-voltage nezintambo.

I-XLPE: I-Cross-linked polyethylene iwuhlobo oluthuthukisiwe lwempahla ye-polyethylene ngemva kokuguqulwa.Ngemuva kokuthuthukiswa, izakhiwo zayo ezingokwenyama namakhemikhali ziye zathuthukiswa kakhulu uma kuqhathaniswa nempahla ye-PE, futhi ngesikhathi esifanayo, izinga layo lokumelana nokushisa liye lathuthukiswa kakhulu.Ngakho-ke, izintambo nezintambo ezenziwe nge-cross-linked polyethylene insulation material zinezinzuzo ukuthi izintambo ze-polyethylene insulation material nezintambo azikwazi ukufana: isisindo esilula, ukumelana nokushisa okuhle, ukumelana nokugqwala, ukumelana nokushisa okukhulu, njll.

Uma kuqhathaniswa ne-thermoplastic polyethylene, ukwahlukanisa kwe-XLPE kunezinzuzo ezilandelayo:

I-1 Ukuthuthukiswa kokumelana nokushisa kokushisa, izakhiwo ezithuthukisiwe zemishini ekushiseni okuphezulu, ukuphikiswa okuthuthukisiwe kokucindezeleka kwemvelo nokumelana nokushisa ukuguga.

2 Ukuqina kwamakhemikhali okuthuthukisiwe kanye nokumelana ne-solvent, ukugeleza okubandayo okuncishisiwe, ngokuyisisekelo kugcinwe izakhiwo zikagesi zangempela, izinga lokushisa lesikhathi eside lokusebenza lingafinyelela ku-125 ℃ no-150 ℃, izintambo ezixhunywe nge-polyethylene ezihlanganisiwe nezintambo, futhi kuthuthukiswe amandla okuthwala isiyingi esifushane, Izinga lokushisa lesikhathi esifushane lingafinyelela ku-250 ℃, ukushuba okufanayo kwezintambo nezintambo, umthamo wamanje wokuthwala we-polyethylene oxhumeke kakhulu mkhulu kakhulu.

Izintambo ezi-3 ze-XLPE ezifakwe ngaphakathi kanye nezintambo zinezakhiwo ezinhle kakhulu zokumelana nemishini, i-waterproof kanye ne-radiation, ngakho-ke zisetshenziswa kabanzi.Okufana nalokhu: izintambo zokuxhuma zangaphakathi zezinto zikagesi, amalayini emoto, izibani zokukhanyisa, izintambo zezimoto ezine-voltage ephansi, izintambo zesitimela, izintambo ezihamba ngaphansi kanye nezintambo, izintambo zokuvikela imvelo ezimayini, izintambo zasolwandle, izintambo zokubeka amandla enuzi, izintambo ze-TV ezinamandla kagesi. , i-X-RAY edubula izintambo ezinamandla kagesi, nezintambo ezidlulisa amandla nezintambo nezinye izimboni.

Umehluko phakathi kwezinto zokufakwa kwamakhebula i-PVC, i-PE, ne-XLPE

I-PVC: izinga lokushisa eliphansi lokusebenza, ukuphila okufushane okushisayo okushisayo, umthamo omncane wokudlulisela, umthamo ophansi wokugcwala, kanye nentuthu enkulu nezingozi zegesi ene-asidi uma kuba nomlilo.Imikhiqizo evamile embonini yocingo nekhebula, izakhiwo ezinhle zomzimba nezomshini, ukusebenza kahle kokucubungula, izindleko eziphansi kanye nentengo yokuthengisa.Kodwa iqukethe ama-halogen, futhi ukusetshenziswa kwe-sheath kukhulu kakhulu.

I-PE: Izakhiwo zikagesi ezinhle kakhulu, nazo zonke izinzuzo ze-PVC ezishiwo ngenhla.Okuvame ukusetshenziswa ekuhlukaniseni izintambo noma ikhebula, ukwahlukanisa imigqa yedatha, ukungaguquguquki kwe-dielectric ephansi, kulungele imigqa yedatha, imigqa yokuxhumana, kanye nokwahlukanisa izintambo eziwumgogodla wekhompyutha wekhompyutha.

I-XLPE: Icishe ibe yinhle njenge-PE ezindaweni zikagesi, kuyilapho izinga lokushisa lesikhathi eside lokusebenza liphakeme ngokuqhathaniswa ne-PE, izakhiwo zemishini zingcono kune-PE, futhi ukumelana nokuguga kungcono.Uhlobo olusha lomkhiqizo ohambisana nemvelo onokumelana okuhle kwezinga lokushisa eliphezulu nokumelana nemvelo, ipulasitiki ye-thermosetting.Okuvame ukusetshenziswa ezintanjeni zikagesi nasezindaweni ezinezidingo eziphakeme zokumelana nemvelo.

Umehluko phakathi kwe-XLPO ne-XLPE

I-XLPO (i-polyolefin exhunywe ngokuphambano): I-EVA, intuthu ephansi ne-halogen-free, i-radiation cross-linked noma i-vulcanized rubber cross-linked olefin polymer.Igama elijwayelekile lekilasi lama-thermoplastic resins atholwe nge-polymerizing noma nge-copolymerizing α-olefin efana ne-ethylene, i-propylene, i-1-butene, i-1-pentene, i-1-hexene, i-1-octene, i-4-methyl-1-pentene, namanye ama-cycloolefins .

I-XLPE (i-polyethylene exhunywe esiphambanweni): I-XLPE, i-polyethylene exhumene, i-silane cross-linking noma i-chemical cross-linking, iyinhlaka ye-thermoplastic eyenziwe nge-polymerization ye-ethylene.Embonini, kuhlanganisa nama-copolymers e-ethylene kanye nenani elincane le-α-olefins.
