Lapho isistimu yekhebula ibekwe ngaphansi komhlaba, endaweni engaphansi komhlaba noma emanzini athambekele ekuqongeleleni amanzi, ukuze kuvinjwe umhwamuko wamanzi namanzi ukuthi angangeni kungqimba lwekhebula lokufaka ikhebula futhi kuqinisekiswe impilo yesevisi yekhebula, ikhebula kufanele lisebenzise Isakhiwo sesendlalelo se-radial esingenakukwazi ukungena, esihlanganisa igobolondo lensimbi kanye nesheya eyinhlanganisela yensimbi-yepulasitiki. Umthofu, ithusi, i-aluminium nezinye izinto zensimbi zivame ukusetshenziswa njengemigoqo yensimbi yezintambo; Itheyiphu eyinhlanganisela yensimbi-yepulasitiki kanye neshethi ye-polyethylene yakha uhlaka lwensimbi-yeplastiki eyinhlanganisela yekhebula. I-Metal-plastic composite sheathing, eyaziwa nangokuthi i-comprehensive sheathing, ibonakala ngokuthambile, ukuphatheka, kanye nokungena kwamanzi kuncane kakhulu kunepulasitiki, i-rubber sheathing, ilungele izindawo ezinezidingo zokusebenza eziphezulu zokungangeni kwamanzi, kodwa uma kuqhathaniswa nokushelela kwensimbi, inhlanganisela yensimbi nepulasitiki. sheathing kusenokungena okuthile.
Ezindinganisweni zaseYurophu zekhebula le-voltage ephakathi nendawo njenge-HD 620 S2: 2009, NF C33-226: 2016, UNE 211620: 2020, itheyiphu ye-aluminium enohlangothi olulodwa ehlanganiswe nepulasitiki isetshenziswa njengesembozo esibanzi esingangeni manzi sezintambo zikagesi. Isendlalelo sensimbi sohlangothi olulodwai-aluminium tape eyenziwe ngepulasitikiixhumene ngqo nesihlangu sokuvikela, futhi idlala indima yesihlangu sensimbi ngesikhathi esifanayo. Ngokwendinganiso yaseYurophu, kuyadingeka ukuhlola amandla okukhumula phakathi kwetheyiphu ye-aluminium eboshwe ngepulasitiki kanye neshethi yekhebula futhi kwenziwe izivivinyo zokumelana nokugqwala ukukala ukumelana kwamanzi e-radial ekhebula; Ngesikhathi esifanayo, kuyadingeka futhi ukukala ukumelana kwe-DC kwe-tape ye-aluminium ehlanganiswe nepulasitiki ukukala amandla ayo okuthwala i-short circuit current.
1. Ukuhlukaniswa kwe-tape ye-aluminium ehlanganiswe nepulasitiki
Ngokwenombolo ehlukene yefilimu yepulasitiki ehlanganiswe ne-aluminium substrate material, ingahlukaniswa ibe izinhlobo ezimbili zenqubo yokumboza i-longitudinal: itheyiphu ye-aluminium enezinhlangothi ezimbili ehlanganiswe ne-aluminium kanye ne-plastic enohlangothi olulodwa ehlanganiswe ne-aluminium tape.
Ungqimba olubanzi oluvikelayo olungangenwa amanzi nomswakama oluvikela umswakama lwezintambo zamandla kagesi aphakathi nendawo naphansi kanye nezintambo zokukhanya ezakhiwe ngethayiphu ye-aluminium enamaceleni ekabili ehlanganiswe ne-polyethylene, i-polyolefin nokunye ukugcoba kudlala indima yamanzi e-radial kanye nobufakazi bomswakama. Itheyiphu ye-aluminium enohlangothi olulodwa ehlanganiswe nepulasitiki isetshenziswa kakhulu ukuvikela izintambo zensimbi.
Kwezinye izindinganiso zaseYurophu, ngaphezu kokusetshenziswa njengesigodlo esibanzi esingangeni manzi, itheyiphu ye-aluminium enohlangothi olulodwa ehlanganiswe nepulasitiki iphinde isetshenziswe njengesihlangu sensimbi samakhebuli kagesi aphakathi nendawo, futhi ukuvikela itheyiphu ye-aluminium kunezinzuzo ezisobala zezindleko uma kuqhathaniswa nesivikelo sethusi.
2. Inqubo yokugoqa ye-longitudinal ye-tape ye-aluminium ehlanganiswe nepulasitiki
Inqubo yokugoqa yobude bomucu oyinhlanganisela ye-aluminium-plastic isho inqubo yokuguqula itheyiphu ye-aluminium embozwe ngepulasitiki isuke esimweni esiyisicaba sangempela iye esimeni seshubhu ngochungechunge lokuguquguquka kwesikhunta, nokuhlanganisa imiphetho emibili yetheyiphu ye-aluminium ehlanganiswe nepulasitiki. Imiphetho emibili yetheyiphu ye-aluminium ehlanganiswe nepulasitiki iyisicaba futhi ibushelelezi, imiphetho iboshwe ngokuqinile, futhi akukho ukuxebuka kwe-aluminium-plastiki.
Inqubo yokushintsha itheyiphu ye-aluminium ehlanganiswe ngepulasitiki isuke esizindeni iye ekumeni kweshubhu ingenziwa kusetshenziswa i-longitudinal wrapping die eyakhiwe ngophondo olugoqayo lwe-longitudinal, umugqa wokuzinzisa kanye nokufakela usayizi. Umdwebo wokugeleza we-longitudinal wrapping molding die of the plastic camera tape ye-aluminium kukhonjiswe esithombeni esilandelayo. Imiphetho emibili ye-tape ye-aluminium ehlanganiswe nepulasitiki eneshubhu ingahlanganiswa yizinqubo ezimbili: ukubopha okushisayo nokubopha okubandayo.
(1) Inqubo yokuhlanganisa okushisayo
Inqubo yokuhlanganisa okushisayo iwukusebenzisa ungqimba lwepulasitiki lwethayiphu ye-aluminium ehlanganiswe nepulasitiki ukuze ithambe ku-70~90℃. Enqubweni yokuguqulwa kwetheyiphu ye-aluminium ehlanganiswe nepulasitiki, ungqimba lwepulasitiki ekuhlanganiseni kwetheyiphu ye-aluminium ehlanganiswe nepulasitiki luyashiswa kusetshenziswa isibhamu somoya oshisayo noma i-blowtorch flame, futhi imiphetho yomibili yetheyiphu ye-aluminium ehlanganiswe ngepulasitiki ihlanganiswa kusetshenziswa i-viscosity. ngemuva kokuthambisa kwesendlalelo sepulasitiki. Namathisela amachopho amabili etheyiphu ye-aluminium ehlanganiswe nepulasitiki ngokuqinile.
(2) Inqubo yokuhlanganisa ebandayo
Inqubo ebandayo yokubopha ihlukaniswe yaba izinhlobo ezimbili, enye iwukwengeza ukufa okuzinzile okude phakathi kwe-caliper die kanye nekhanda le-extruder, ukuze i-tape ye-aluminium ehlanganiswe nepulasitiki igcine isakhiwo se-tubula esizinzile ngaphambi kokungena ekhanda le-extruder. , ukuphuma kwefasi elizinzile kuseduze nokuphuma kwe-die core ye-extruder, kanye nenhlanganisela ye-aluminium-plastic ngokushesha ingena ku-die core we-extruder ngemva kokukhipha ukufa okuzinzile. Ingcindezi ye-extrusion ye-sheath material igcina isakhiwo se-tubular sethayiphu ye-aluminium ehlanganiswe nepulasitiki, futhi izinga lokushisa eliphezulu lepulasitiki ekhishwe lithambisa ungqimba lwepulasitiki lwe-aluminium ehlanganiswe nepulasitiki ukuze kuqedelwe umsebenzi wokubopha. Lobu buchwepheshe bufaneleka kabili emaceleni elaminethiwe i-aluminium tape ehlanganiswe ne-aluminium, imishini yokukhiqiza ilula ukusebenza, kodwa ukucubungula isikhunta kuyinkimbinkimbi, futhi itheyiphu ye-aluminium ehlanganiswe nepulasitiki kulula ukuyibuyisela.
Enye inqubo ebandayo yokubopha iwukusetshenziswa kwe-adhesive enamathelayo encibilikayo eshisayo, ingcina ye-adhesive encibilikisiwe encibilikisiwe umshini wokukhipha isikhunta endaweni yokugoqa uphondo lwe-longitudinal olucindezelwe ohlangothini olulodwa lomphetho wangaphandle wetheyiphu ye-aluminium ehlanganiswe nepulasitiki, izikhundla ezimbili ezinqenqemeni zepulasitiki. itheyiphu ye-aluminium embozwe emugqeni ozinzile futhi usayizi uyafa ngemva kokunamathela okunamathelayo okuncibilika okushisayo. Lobu buchwepheshe bufanele kokubili i-aluminiyamu ehlanganiswe ngepulasitiki enezinhlangothi ezimbili kanye ne-aluminiyamu ehlanganiswe ne-plastic eyodwa. Imishini yayo yokucubungula isikhunta kanye nokukhiqiza kulula ukuyisebenzisa, kodwa umphumela wayo wokubopha uthintwa kakhulu izinga lokunamathiswa okuncibilika okushisayo.
Ukuze kuqinisekiswe ukwethembeka kokusebenza kwesistimu yekhebula, isihlangu sensimbi kufanele sixhunywe ngogesi nesivikelo sokugxilisa ikhebula, ngakho-ke i-tape ye-aluminium ehlanganiswe nepulasitiki ehlangene kufanele isetshenziswe njengesihlangu sensimbi sekhebula. Isibonelo, inqubo yokubopha okushisayo okukhulunywe ngayo kuleli phepha ifaneleka kabili emacelenii-aluminium tape eyenziwe ngepulasitiki, kuyilapho inqubo yokuhlanganisa ebandayo kusetshenziswa ingcina encibilikayo eshisayo ifaneleka kakhulu kuthayiphu ye-aluminium enamapulastiki ehlanganiswe nohlangothi olulodwa.
