Umbhobho wentsimbi ogqunywe ngeplastiki
Inkcazelo emfutshane:
Imibhobho yentsimbi egqunywe ngeplastiki yangaphakathi nangaphandle yenziwa ngokunyibilikisa umaleko wepolyethylene (PE) resin, i-ethylene-acrylic acid copolymer (EAA), umgubo we-epoxy (EP), kunye nepolycarbonate engeyiyo ityhefu enobunzima obuyi-0.5 ukuya kwi-1.0mm eludongeni lwangaphakathi lombhobho wensimbi.Umbhobho odibeneyo wensimbi-yeplastiki eyenziwe ngezinto eziphilayo ezifana nepropylene (PP) okanye i-polyvinyl chloride engeyiyo inetyhefu (PVC) ayinayo nje inzuzo yamandla aphezulu, ukudibanisa okulula, kunye nokuchasana nokuhamba kwamanzi, kodwa iphinda yoyise ukubola kwentsimbi. imibhobho xa ibekwe emanzini.Ukungcola, ukulinganisa, amandla aphantsi emibhobho yeplastiki, ukusebenza kakubi komlilo kunye nezinye iintsilelo, ubomi bokuyila bunokufikelela kwiminyaka engama-50.Eyona nto iphosakeleyo kukuba akufanele igobe ngexesha lofakelo.Ngethuba lokucutshungulwa kwe-thermal kunye ne-welding ye-electric cutting, indawo yokusika kufuneka ifakwe ipeyinti kunye ne-non-toxic evamile yokushisa ukushisa iglue enikezelwa ngumenzi ukulungisa inxalenye eyonakalisiweyo.

Iinzuzo zemveliso yombhobho wentsimbi efakwe ngeplastiki:
1. Ziqhelanise nemekobume engcwatyiweyo nefumileyo, kwaye inokumelana namaqondo obushushu aphezulu naphantsi kakhulu.
2. Ikhono elinamandla lokuchasana nokuphazamiseka, ukuba umbhobho wensimbi owenziwe ngeplastiki usetyenziswa njenge-cable bushing, unokukhusela ngokufanelekileyo ukuphazamiseka kwesignali yangaphandle.
3. Amandla oxinzelelo olulungileyo, uxinzelelo oluphezulu lunokufikelela kwi-6Mpa.
4. Ukusebenza kakuhle kwe-insulation, njengetyhubhu yokukhusela iingcingo, ukuvuza akusoze kwenzeke.
5. Akukho burr, udonga lombhobho olugudileyo, olulungele ukunxiba iingcingo okanye iintambo ngexesha lolwakhiwo.
Inkcazo, iindidi, kunye neendlela zokudibanisa kwimibhobho yentsimbi ehlanganiswe ngeplastiki yeentambo ziye zahluka.Phakathi kwazo, iinkcukacha ezincinci zinokuveliswa ukuya kwi-15mm, kwaye akukho zithintelo kwizinto ezinkulu.Iindidi zayo zenziwe ngegalvanized ngaphandle, iplastiki igqunywe ngaphakathi nangaphandle, njl. njl., kwaye luhlobo oluguquguqukayo olunokusetyenziswa kuyo nayiphi na enye imimandla.Indlela yokudibanisa ithatha i-welding, i-groove, i-flange kunye ne-buckle wire connection, kunye ne-welding inokwamkela i-bimetal okanye i-welding engonakalisiyo.
