Zithini izicelo ze-CPE impact modifiers kwiintambo kunye neentambo?

I-CPE (i-Chlorinated Polyethylene), njengesiguquli sempembelelo, isetyenziswa kakhulu kwicandelo leentambo kunye neentambo ukuphucula ukusebenza ngokupheleleyo kwezinto kunye nokufezekisa usetyenziso oluphambili. Imisebenzi yayo ephambili ibonakala kwezi zinto zilandelayo:
1, Uphuculo oluphambili lokusebenza
1. Ukumelana nobushushu obuphuculweyo kunye nokuthembeka
Ubushushu bokusebenza bexesha elide beentambo ezilungisiweyo ze-CPE bunokufikelela kwi-90 ℃ (ifomyula elungisiweyo ingafikelela kwi-105 ℃), iphezulu kakhulu kunomda ophezulu we-60-65 ℃ wezixhobo zerabha zemveli, ngelixa iphucula ukuguga kobushushu kunye nokusebenza kokumelana ne-ozone. Ulwakhiwo lwayo lwemolekyuli egcweleyo lubonelela ngokumelana okuhle kwemozulu kwaye luziqhelanisa neendawo zangaphandle ezinzima.
2. Ukuphuculwa kokungatshisi ilangatye kunye nokhuseleko
Iiathom eziqulathe i-chlorine zinika i-CPE amandla okuthintela ilangatye, zihlangabezana nemigangatho yokhuseleko efana ne-UL-94, ifanelekile ngakumbi kwiimeko ezinobungozi obukhulu ezifana neentambo zokwemba. Ivelisa umsi omncinci ngexesha lokutsha kwaye ayikhuphi iigesi ezinobuthi obukhulu.
3. Ukulungiswa kokusebenza koomatshini
Ukongeza i-CPE kunokunyusa amandla okuchaphazeleka kweesheya zekhebula (amandla okuchaphazeleka anyuswa izihlandlo ezi-3-4 emva kokongeza iinxalenye ezi-8-10 ze-CPE kwizinto ezisisiseko ze-PVC), kwaye kuphucule ukuxhathisa ioyile, ukuxhathisa ukugoba, kunye nokuxhathisa ukuguguleka, nto leyo eyandisa ubomi benkonzo.
Iingenelo zenkqubo kunye neendleko
1. Ukuziqhelanisa nokucubungula
Uluhlu lobushushu bokuxuba lwe-CPE lubanzi (50-160 ℃), kunye neempawu ze-roller ezinganamatheliyo kunye neempawu ezingatshisiyo, nto leyo ephucula kakhulu ukusebenza kakuhle kwemveliso. I-compound yerabha exutyiweyo isengasetyenziswa ngokuzinzileyo emva kokuba igcinwe kubushushu begumbi iminyaka eli-1-2.
2. Ukusebenza kakuhle kweendleko
Iimpawu ezilungileyo zokuzalisa (ezikwaziyo ukwamkela ubuninzi beempuphu zeeminerali ezifana necalcium carbonate) zinciphisa umxholo wejeli ube ngaphantsi kwe-25% ngelixa zigcina iimpawu ezibonakalayo kwaye ziphucula iindleko zemveliso.
Iimeko zesicelo esikhethekileyo
Ukhuseleko lwe-insulation layer: I-CPE ayingcolisi i-copper core xa isetyenziswa njenge-insulation layer ene-voltage ephantsi, iqinisekisa uzinzo lwe-conductivity.
Umbala kunye noKhuseleko lweNdalo: Umbala omhlophe osisiseko uxhasa umbala oqaqambileyo, othatha indawo yerabha yendalo/irabha ye-chloroprene etyheli; Kuphephe ukuguquguquka kwezinyibilikisi ezinetyhefu eninzi ngexesha lenkqubo yemveliso.
Iintambo ezikhethekileyo: Iimeko ezifunwa kakhulu ezifana neentambo zemigodi yamalahle, iintambo zelifti, kunye neentambo zomatshini wokuwelda zixhomekeke kwiimpawu zazo ezidibeneyo zokuxhathisa ioyile, ukumelana nobushushu, kunye nokungacimi komlilo.
