Yintoni umahluko phakathi kwemathiriyeli yokugquma intambo iPE, iPVC, kunye neXLPE?

Okwangoku, izixhobo zokugquma intambo ezisetyenziswa kwimveliso yentambo zahlulwe ngokweendidi ezintathu: PE, PVC, kunye neXLPE.Oku kulandelayo kwazisa umahluko phakathi kwezinto zokugquma i-PE, i-PVC, kunye ne-XLPE esetyenziswa kwiintambo.

EI-xplanation yokwahlula kunye neempawu zezixhobo zokugquma intambo

I-PVC: I-Polyvinyl chloride, i-polymer eyenziwe yi-polymerization yamahhala ye-vinyl chloride monomers phantsi kweemeko ezithile.Ineempawu zozinzo, ukumelana ne-asidi, ukuxhathisa kwe-alkali, ukuxhathisa ukubola, kunye nokumelana nokuguga, kwaye isetyenziswa ngokubanzi kwizinto zokwakha, iimfuno zemihla ngemihla, imibhobho kunye nemibhobho, iingcingo kunye neentambo, kunye nezinto zokutywina.Yahlulahlulwe ibe yithambile kwaye ilukhuni: ezithambileyo zisetyenziswa ikakhulu ukwenza izinto zokupakisha, iifilimu zezolimo, njl., kwaye zisetyenziswa ngokubanzi ekwenzeni iileya zocingo kunye nentambo yokugquma, njengeentambo eziqhelekileyo zepolyvinyl chloride ezigqunywe ngamandla;ngelixa ezilukhuni zisetyenziselwa ukwenza imibhobho kunye neepleyiti.Eyona nto inkulu yezinto ezibonakalayo ze-polyvinyl chloride yi-flame retardancy, ngoko isetyenziswa ngokubanzi kwintsimi yokuthintela umlilo kwaye yenye yezona zinto zisetyenziswa ngokuqhelekileyo izixhobo zokukhusela i-flame retardant kunye ne-fire-resistant-retardancy kunye neentambo.

I-PE: I-Polyethylene yi-resin ye-thermoplastic eyenziwe nge-polymerization ye-ethylene.Ayinatyhefu kwaye ayinabungozi, inokumelana nobushushu obuphantsi kakhulu, kwaye inokumelana nokhukuliseko lweeasidi ezininzi kunye nealkali, kwaye inokusebenza okugqwesileyo kokufakwa kombane.Ngelo xesha, ngenxa yokuba i-polyethylene ineempawu ze-non-polarity, ineempawu zokulahlekelwa okuphantsi kunye ne-conductivity ephezulu, ngoko ke isetyenziswa ngokubanzi njengento yokukhusela iingcingo eziphezulu ze-voltage kunye neentambo.

I-XLPE: I-polyethylene edibeneyo yindlela ephakamileyo ye-polyethylene impahla emva kokuguqulwa.Emva kokuphuculwa, iimpawu zayo zomzimba kunye neekhemikhali ziphuculwe kakhulu xa kuthelekiswa nezinto ze-PE, kwaye kwangaxeshanye, inqanaba lokumelana nobushushu liphuculwe kakhulu.Ke ngoko, iingcingo kunye neentambo ezenziwe nge-cross-linked polyethylene insulation material zineengenelo zokuba i-polyethylene insulation iingcingo kunye neentambo azikwazi ukungqamanisa: ubunzima bokukhanya, ukumelana nobushushu obulungileyo, ukumelana nokugqwala, ukuxhathisa okukhulu kwe-insulation, njl.

Xa kuthelekiswa ne-thermoplastic polyethylene, ukugqunywa kwe-XLPE kunezi nzuzo zilandelayo:

I-1 Ukuphucula ukuchasana nokuguqulwa kobushushu, ukuphuculwa kweepropathi zomatshini kwiqondo lokushisa eliphezulu, ukuphucula ukunyanzeliswa koxinzelelo lwendalo kunye nokuchasana nokuguga.

2 Uzinzo oluphuculweyo lweekhemikhali kunye nokumelana ne-solvent, ukuhamba okubandayo okuncitshisiweyo, ngokusisiseko kugcinwe iipropathi zombane zangaphambili, ubushushu bexesha elide lokusebenza bunokufikelela kwi-125 ℃ kunye ne-150 ℃, i-cross-linked-linked polyethylene insulated iingcingo kunye neentambo, kwakhona kuphuculwe ukuthwala i-short-circuit, yayo. Ubushushu bexesha elifutshane obunobushushu bunokufikelela kuma-250 ℃, ubukhulu obufanayo beengcingo kunye neentambo, i-cross-linked polyethylene yangoku ephethe umthamo omkhulu kakhulu.

I-3 i-XLPE i-insulated iingcingo kunye neentambo zineepropathi ezibalaseleyo zoomatshini, ezingenamanzi kunye ne-radiation, ngoko ke zisetyenziswa ngokubanzi.Ezinje: iingcingo zoqhagamshelo lwangaphakathi lwezixhobo zombane, iintambo zombane, iintambo zokukhanyisa, iingcingo zokulawula i-automotive low-voltage signal controling, iingcingo zelocomotive, iingcingo ze-subway kunye neentambo, iintambo zokhuseleko lwezemigodi, iintambo zaselwandle, iintambo zokubeka amandla enyukliya, iingcingo zeTV ezinombane ophezulu. , X-RAY ukudubula iingcingo high-voltage, iingcingo zombane kunye neentambo kunye namanye amashishini.

Umahluko phakathi kwezixhobo zokugquma intambo yePVC, PE, kunye neXLPE

I-PVC: ubushushu obuphantsi bokusebenza, ubomi obufutshane bokuguga be-thermal, umthamo omncinci wokuhambisa, umthamo ophantsi womthwalo, kunye nomsi omkhulu kunye neengozi zegesi ye-asidi xa kukho umlilo.Iimveliso eziqhelekileyo kwishishini lecingo kunye nentambo, iipropathi ezilungileyo zomzimba kunye noomatshini, ukusebenza kakuhle kokusebenza, ixabiso eliphantsi kunye nexabiso lokuthengisa.Kodwa iqulethe i-halogens, kwaye ukusetyenziswa kwe-sheath yeyona inkulu.

I-PE: Iipropati zombane ezigqwesileyo, nazo zonke iingenelo zePVC ezikhankanywe ngasentla.Ngokuqhelekileyo isetyenziswe kwi-insulation ye-wire okanye i-cable insulation, i-insulation line data, i-dielectric constant ephantsi, ilungele imigca yedatha, imigca yonxibelelwano, kunye ne-computer peripheral core insulation.

I-XLPE: Phantse ilungile njenge-PE kwiipropati zombane, ngelixa ubushushu bexesha elide lokusebenza liphezulu kune-PE, iimpawu zomatshini zingcono kune-PE, kwaye ukuchasana nokuguga kungcono.Uhlobo olutsha lwemveliso ehambelana nokusingqongileyo kunye nokumelana nokushisa okuphezulu kunye nokumelana nokusingqongileyo, iplastiki ye-thermosetting.Isetyenziswa ngokuqhelekileyo kwiingcingo zombane kunye neendawo ezineemfuno zokuchasana nokusingqongileyo.

Umahluko phakathi kweXLPO kunye neXLPE

I-XLPO (i-polyolefin edibeneyo): i-EVA, umsi ophantsi kunye ne-halogen-free, i-radiation cross-linked okanye i-vulcanized rubber cross-linked olefin polymer.Igama eliqhelekileyo leklasi ye-thermoplastic resins efunyenwe nge-polymerizing okanye i-copolymerizing α-olefins efana ne-ethylene, ipropylene, i-1-butene, i-1-pentene, i-1-hexene, i-1-octene, i-4-methyl-1-pentene, kunye nezinye i-cycloolefins. .

I-XLPE (i-polyethylene edibeneyo): I-XLPE, i-polyethylene edibeneyo, i-silane cross-linking okanye i-chemical cross-linking, i-resin ye-thermoplastic eyenziwe nge-polymerization ye-ethylene.Kwishishini, ikwabandakanya i-copolymers ye-ethylene kunye nenani elincinci le-α-olefins.
