Isikhokelo soKhetho lwe-Inner Lining kunye ne-Inner Sheath Materials kwiintambo ezithintela umlilo ezingenamsi ophantsi ezingenawo i-halogen

Kuyilo lweentambo ezithintela umlilo eziphantsi ezingenamsi we-halogen, ukukhethwa kwezinto zentambo ze-LSZH ze-lining yangaphakathi kunye ne-inner sheath kuchaphazela ngokuthe ngqo ukusebenza kwentambo ethintela umlilo, ukhuseleko lokusingqongileyo, kunye nobomi benkonzo. I-inner lining ibekwe phakathi kwe-insulation kunye ne-armor, ibonelela ngokukhusela kunye nokwahlukanisa; i-inner sheath ibekwe ngaphandle kwe-armor, inika ukhuseleko olupheleleyo. Zombini kufuneka zihlangabezane neemfuno zokuba zingena-halogen, zingabi nomsi kakhulu, zingabi nomsi kakhulu, kwaye zingabi nobuhlobo nokusingqongileyo.

I. Ukukhethwa kwezinto zokufakelwa ngaphakathi kwiintambo ezingenamsi ophantsi nezithintela ilangatye

Ingaphakathi kufuneka lingabi yi-hygroscopic, libe neempawu ezithintela umlilo ezingenamsi omninzi, kwaye lihambelane nenkqubo yokwambathisa. Izixhobo ze-LSZH zangaphakathi ezisetyenziswa rhoqo ziquka i-polyolefin engenamsi engenamsi kunye ne-polyethylene engenamsi engenamsi (HF-PE), ezibonelela ngeempawu ezintle zoomatshini kunye nozinzo oluthintela umlilo. Iinkqubo zokukhupha okanye zokusonga zingasetyenziswa ukuhlangabezana neemfuno zesakhiwo seenkcazo ezahlukeneyo zekhebula.

II. Ukukhethwa kwezinto zeSingxobo sangaphakathi esingenamsi ophantsi seHalogen

Iimfuno eziphambili zeshelufu yangaphakathi ngumsi omncinci, ukwakheka okungena-halogen, kunye nokungatshisi kakhulu. Izinto eziphambili ziquka i-polyolefin engenamsi omncinci ethintela umlilo kunye nerabha ye-EVM (irabha ye-ethylene-vinyl acetate). I-polyolefin engenamsi omncinci ethintela umlilo ayikhuphi iigesi ze-halogen acid ezinobuthi xa zitsha, nto leyo enika ukucutshungulwa okuhle kunye nokusebenza kakuhle kweendleko. Irabha ye-EVM ibonakalisa ukumelana okugqwesileyo kobushushu obuphezulu, ukumelana neoyile, kunye neempawu ezithintela umlilo ezingaphantsi komsi, nto leyo eyenza ukuba isetyenziswe kakhulu kwizicelo eziphezulu ezifana neentambo zaselwandle, iintambo zemigodi, kunye neentambo zikaloliwe.

III. Ukusetyenziswa kwerabha ye-EVM kwiisheya zekhebula ezingenamsi ophantsi we-halogen

Irabha ye-EVM okwangoku yinto ekhethwayo kwiishelufu zekhebula eziphantsi ezingenanto i-halogen ezingenamsi. Iphumelele iziqinisekiso ezisemthethweni ezithintela umlilo kwiindlela zokusebenzisa iintambo zaselwandle nezemigodi. Iikhompawundi ezithintela umlilo ze-EVM zifumana isalathisi seoksijini esingama-38 ukuya kuma-42, zivelisa ukukhutshwa komsi okuphantsi, kwaye azinabungozi xa zitsha. Ngomgangatho wobushushu obusebenzayo oqhubekayo ukusuka kuma-90°C ukuya kwi-105°C, kunye nokumelana okuhle kakhulu neeoyile zeminerali kunye nokuguga, irabha ye-EVM yinto efanelekileyo kwiintambo ezikhethekileyo ezithintela umlilo.

IV. Uhlalutyo lweendleko kunye neenzuzo zezinto zekhebula ezingenamsi ophantsi we-halogen

Izixhobo zekhebula ze-LSZH ngokubanzi zibiza kakhulu kunezesiqheloI-PVCiintambo, ngokuyintloko ngenxa yeenkqubo ezigcina ilangabi zingenabungozi kokusingqongileyo ezifana ne-magnesium hydroxide kunye ne-aluminium hydroxide. Nangona kunjalo, kwizicelo ezibalulekileyo zokhuseleko ezifana nezothutho lukawonke-wonke, amaziko edatha, iinqanawa zaselwandle, kunye nezakhiwo eziphakamileyo, ixabiso lokhuseleko lwezixhobo zekhebula ezingenamsi ophantsi we-halogen azinakutshintshwa. Okwangoku, ii-polyolefins ze-EVM zerabha kunye ne-halogen-free-performance high-performance ziye zafumana izicelo ezinkulu ezingabizi kakhulu kwaye ziye zaba zikhetho eziphambili kushishino.

Isiphelo
Ukukhetha i-inside lining efanelekileyo kunye nezixhobo ze-inner sheath ezifanelekileyo kwiintambo ezithintela umlilo ezingenamsi omninzi ezingena-halogen kufuna ukuqwalaselwa ngokubanzi kokunganyamezelani komlilo, iimfuno zokusingqongileyo, iimeko zokusetyenziswa, kunye nokusebenza kakuhle kweendleko.IHLABATHI ELINYEIngcali ekunikezeleni uluhlu olupheleleyo lwezixhobo zekhebula ze-LSZH, kubandakanya irabha ye-EVM, i-polyolefin engenamsi omninzi engenamlilo, kunye neekhompawundi zekhebula ezingenamlilo ezingenamlilo ze-halogen, zibonelela ngezisombululo zezinto zekhebula ezima kunye nenkxaso yobugcisa.
