Tlhahisong ea lithapo, khetho ea thepa ea ho thibela ho ruruha e ama ka kotloloho ts'ebetso ea sehlahisoa, bophelo ba ts'ebeletso, le polokeho ea ts'ebetso. Lisebelisoa tsa ho thibela ho ruruha tse sebelisoang haholo kajeno li kenyelletsa Polyvinyl Chloride (PVC), Polyethylene (PE), le Cross-linked Polyethylene (XLPE). Ka lebaka la libopeho tsa tsona tse ikhethang tsa limolek'hule le thepa ea thepa, e 'ngoe le e 'ngoe e loketse maemo a fapaneng a ts'ebeliso.
1. Ho kenya mocheso ka polyvinyl chloride (PVC)
PVC ke e 'ngoe ea thepa ea ho thibela mollo e sebelisoang haholo, e tsebahalang ka matla a eona a matle a mechini, bonolo ba ho e sebetsana, le ho hanyetsa li-acid le alkali hantle. Ka ho kenyelletsa lintho tse eketsang tse thibelang mollo sebopehong sa eona, ho thibela mollo ka PVC ho ka fihlella ts'ebetso e sebetsang ea ho thibela mollo, e leng se etsang hore e lokele lithapo le likhoele tsa merero e akaretsang.
Ho latela boima, PVC e tenyetsehang e sebediswa haholo bakeng sa dikarolo tsa ho kenya mocheso, ha PVC e tiileng e sebediswa hangata e le sekwahelo sa thapo. Ho lokela ho hlokomelwa hore mocheso o dumelletsweng wa nako e telele wa tshebetso (mocheso wa conductor) wa dithapo tse kentsweng mochesong wa PVC hangata ke 70 °C, mme PVC e ka hlahisa mosi o teteaneng ha e pepesehetse mollo.
2. Ho kenya thepa ka polyethylene (PE)
Ho thibela motlakase ha PE ho khetholloa ka thepa ea eona e ikhethang ea motlakase, ho kenyeletsoa le ho se fetohe ha motlakase ho tlase, tahlehelo e tlase ea motlakase, le ho hanyetsa molumo o phahameng, e leng se etsang hore e tšoanelehe haholo bakeng sa phetiso ea lets'oao la maqhubu a phahameng. Ho phaella moo, PE e bontša ts'ebetso e ntle ea mocheso o tlase le botsitso ba lik'hemik'hale.
Likhoele tse nang le insulation ea PE li sebelisoa haholo likhoeleng tsa puisano ea data, likhoele tsa coaxial, le likhoele tsa motlakase tse nang le motlakase o tlase ho isa ho o mahareng. Mocheso o lumelletsoeng oa ts'ebetso ea nako e telele (mocheso oa conductor) oa insulation ea PE hangata ke 70 °C.
3.Polyethylene e hokahaneng le sefapano (XLPE)Ho kenya mocheso
XLPE ke thepa ea thermosetting e hlahisoang ka ho hokahanya sebopeho sa limolek'hule tse otlolohileng tsa PE ka lik'hemik'hale kapa ka 'mele ho ea marang-rang a mahlakore a mararo. Ts'ebetso ena ea ho hokahanya e fella ka ntlafatso e kholo ts'ebetsong ea thepa.
Ho kenya thepa ka XLPE ho fana ka:
Mocheso o sebetsang o lumelletsoeng oa nako e telele o eketsehile ho fihla ho 90 °C
Khanyetso ea mocheso oa potoloho e khuts'oane ho fihlela ho 250 °C
Matla a ntlafalitsoeng a mechini le khanyetso e ntlafetseng khahlanong le ho petsoha ha khatello ea tikoloho
Ka nako e ts'oanang, XLPE e boloka thepa e ntle ea motlakase ea PE. Ka lebaka leo, XLPE e fetohile thepa e ratoang ea ho thibela mocheso bakeng sa likhoele tsa motlakase tse mahareng le tse phahameng, likhoele tse ncha tsa matla, le lits'ebetso tsa indasteri tse nang le maemo a ts'ebetso a boima.
4. Tataiso ea Khetho ea Kopo
PVC-Likhoele tse nang le insulation: Li theko e tlase ebile li sebetsa, li loketse terata ea ka tlung, likhoele tsa taolo e akaretsang, le libaka tse ling tse tloaelehileng tse omileng.
Likhoele tse nang le insulation ea PE: Tshebetso e phahameng ea motlakase, e loketseng puisano ea data, phetiso ea matšoao, le lits'ebetso tse hlokang litšobotsi tse tsitsitseng tsa bokhoni.
Likhoele tse nang le insulation ea XLPE: Tshebetso e phahameng e felletseng, e khothaletsoang marangrang a mokokotlo oa phetisetso ea motlakase, libaka tse nang le mocheso o phahameng, maemo a mongobo, le lits'ebetso tsa indasteri tse nang le litlhoko tse phahameng haholo tsa ts'epo.
Litšebelisong tsa boenjiniere bo sebetsang, khetho ea thepa ea ho futhumatsa e lokela ho nahana ka mocheso oa ts'ebetso, maemo a tikoloho, liparamente tsa motlakase, litlhoko tsa mechini, le tekanyetso ea litšenyehelo. Ka tsoelo-pele e tsoelang pele ea theknoloji le tlhahiso e kholo, karolelano ea litšenyehelo le ts'ebetso ea likhoele tsa XLPE e ntse e ntlafala, e leng se lebisang ho mefuta e mengata ea lits'ebetso tsa tsona.
Mabapi le rona
Jwalo ka mofani wa thepa ya thapo ya profeshenale, ONE WORLD e thehile mela e felletseng ya tlhahiso bakeng sa metswako ya ho kwahela ya PE, XLPE, le PVC, e tshehetswang ke disebediswa tse tswetseng pele tsa teko tse kang Melt Flow Rate Testers, Hot Set / Heat Elongation Testers, le High-Voltage Breakdown Test Systems, e fanang ka motheo o tiileng wa hardware bakeng sa netefatso ya boleng ba sehlahiswa.
