Hajoale, lisebelisoa tsa ho kenya lithapo tse sebelisoang tlhahisong ea lithapo li arotsoe ka mekhahlelo e meraro: PE, PVC le XLPE.Se latelang se hlahisa phapang lipakeng tsa thepa e sireletsang PE, PVC, le XLPE e sebelisoang likhoeleng.
Explanation ea karohano le litšobotsi tsa kabel insulating thepa
PVC: Polyvinyl chloride, polymer e entsoeng ke polymerization ea mahala ea vinyl chloride monomers tlas'a maemo a itseng.E na le litšoaneleho tsa botsitso, ho hanyetsa acid, khanyetso ea alkali, ho hanyetsa kutu, le ho hanyetsa botsofali, 'me e sebelisoa haholo ka thepa ea mohaho, litlhoko tsa letsatsi le letsatsi, liphaephe le liphaephe, lithapo le likhoele, le thepa ea ho tiisa.E arotsoe ka tse bonolo le tse thata: tse bonolo li sebelisoa haholo-holo ho etsa thepa ea ho paka, lifilimi tsa temo, joalo-joalo, 'me li sebelisoa haholo ha ho etsoa lisebelisoa tsa terata le li-cable insulated, tse kang lithapo tse tloaelehileng tsa polyvinyl chloride tsa motlakase;athe tse thata ka kakaretso li sebelisoa ho etsa liphaephe le lipoleiti.Ntho e kholo ka ho fetisisa ea thepa ea polyvinyl chloride ke ho lieha ha lelakabe, kahoo e sebelisoa haholo tšimong ea thibelo ea mollo 'me ke e' ngoe ea lisebelisoa tse atisang ho sebelisoa tse sireletsang mollo bakeng sa lithapo le lithapo tse thibelang mollo.
PE: Polyethylene ke resin ea thermoplastic e entsoeng ka polymerization ea ethylene.Ha e na chefo ebile ha e na kotsi, e na le khanyetso e ntle ea mocheso o tlase, 'me e khona ho mamella khoholeho ea li-acids tse ngata le alkali,' me e na le ts'ebetso e ntle haholo ea ho kenya motlakase.Ka nako e ts'oanang, hobane polyethylene e na le litšobotsi tse se nang polarity, e na le litšobotsi tsa tahlehelo e tlaase le conductivity e phahameng, kahoo hangata e sebelisoa e le thepa ea ho kenya letsoho bakeng sa lithapo le likhoele tse phahameng.
XLPE: Polyethylene e kopantsoeng ka sefapano ke mofuta o tsoetseng pele oa thepa ea polyethylene ka mor'a phetoho.Ka mor'a ho ntlafatsa, thepa ea eona ea 'mele le ea lik'hemik'hale e ntlafalitsoe haholo ha e bapisoa le thepa ea PE,' me ka nako e ts'oanang, boemo ba eona ba ho hanyetsa mocheso bo ntlafalitsoe haholo.Ka hona, lithapo le likhoele tse entsoeng ka thepa ea ho kenella ka har'a polyethylene e kopantsoeng li na le melemo eo likhoele le likhoele tsa polyethylene li ke keng tsa tšoana: boima bo bobebe, ho hanyetsa mocheso hantle, ho hanyetsa kutu, khanyetso e kholo e batlang e lekana, joalo-joalo.
Ha ho bapisoa le thermoplastic polyethylene, XLPE insulation e na le melemo e latelang:
1 E ntlafalitse ho hanyetsa mocheso oa mocheso, ho ntlafatsa thepa ea mochine ka mocheso o phahameng, ho ntlafatsa ho hanyetsa khatello ea kelello ea tikoloho le ho hanyetsa botsofali ba mocheso.
2 Ho matlafatsa botsitso ba lik'hemik'hale le ho hanyetsa solvent, ho fokotsa ho phalla ha serame, ha e le hantle ho boloka thepa ea motlakase ea pele, mocheso oa nako e telele oa ho sebetsa o ka fihla ho 125 ℃ le 150 ℃, lithapo le likhoele tsa polyethylene tse kopantsoeng ka sefapano, le tsona li ntlafalitse bokhoni ba ho tsamaisa nako e khutšoanyane. Mocheso oa nako e khuts'oane oa ho jara o ka fihla ho 250 ℃, botenya bo ts'oanang ba lithapo le likhoele, matla a ho jara a polyethylene a hokahantsoeng ke a maholo haholo.
Lithapo tse 3 tsa XLPE tsa insulated li na le lisebelisoa tse ntle tsa mochini, tse sa keneleng metsi le tse hanyetsang mahlaseli, ka hona li sebelisoa haholo.Joalo ka: lithapo tse hokelang ka hare tsa lisebelisoa tsa motlakase, likhoele tsa motlakase, lithapo tsa mabone, lithapo tsa taolo ea motlakase o tlase, lithapo tsa literene, mehala ea terene e tsamaeang ka tlas'a lefatše le likhoele, likhoele tsa ts'ireletso ea tikoloho, lithapo tsa leoatleng, likhoele tse behang matla a nyutlelie, lithapo tsa TV tse nang le motlakase o phahameng. , X-RAY e thunya lithapo tse nang le motlakase o mongata, le lithapo le lithapo tse tsamaisang motlakase le liindasteri tse ling.
Phapang pakeng tsa lisebelisoa tsa ho kenya cable PVC, PE, le XLPE
PVC: mocheso o tlase oa ts'ebetso, bophelo bo khuts'oane ba botsofali, matla a manyane a phetisetso, matla a tlase a boima, le likotsi tse kholo tsa mosi le khase ea asiti ha ho ka chesa.Lihlahisoa tse akaretsang indastering ea terata le ea cable, thepa e ntle ea 'mele le ea mochini, ts'ebetso e ntle ea ts'ebetso, theko e tlase le theko ea thekiso.Empa e na le li-halogen, 'me tšebeliso ea sheath ke eona e kholo ka ho fetisisa.
PE: Lisebelisoa tse ntle tsa motlakase, tse nang le melemo eohle ea PVC e boletsoeng ka holimo.E sebelisoa ka mokhoa o tloaelehileng oa ho kenya mohala kapa mohala, ho kenya data, ho lula fatše ka dielectric, ho loketse mehala ea data, likhoele tsa puisano, le likhomphutha tse fapaneng tsa peripheral wire core insulation.
XLPE: E batla e lekana le PE ka thepa ea motlakase, ha mocheso oa nako e telele oa ts'ebetso o batla o phahame ho feta PE, thepa ea mechine e molemo ho feta PE, 'me ho hanyetsa botsofali ho molemo.Mofuta o mocha oa sehlahisoa se nang le tikoloho se nang le mocheso o motle oa ho hanyetsa mocheso le ho hanyetsa tikoloho, polasetiki ea thermosetting.E sebelisoa hangata ka lithapo tsa elektronike le libakeng tse nang le litlhoko tse phahameng tsa ho hanyetsa tikoloho.
Phapang lipakeng tsa XLPO le XLPE
XLPO (cross-linked polyolefin): EVA, mosi o tlaase le halogen-free, radiation cross-linked kapa vulcanized cross-linked olefin polymer.Lentsoe le akaretsang bakeng sa sehlopha sa li-resin tsa thermoplastic tse fumanoang ka polymerizing kapa copolymerizing α-olefin tse kang ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene, le li-cycloolefins tse ling. .
XLPE (polyethylene e kopantsoeng ka sefapano): XLPE, polyethylene e kopantsoeng ka sefapano, silane cross-linking kapa chemical cross-linking, ke resin ea thermoplastic e entsoeng ke polymerization ea ethylene.Ka indasteri, e boetse e kenyelletsa li-copolymers tsa ethylene le palo e nyenyane ea α-olefin.
