Uma uhlelo lwekhebula lubekwe ngaphansi komhlaba, endaweni engaphansi komhlaba noma emanzini avame ukuqongelela amanzi, ukuze kuvinjelwe umhwamuko wamanzi namanzi ukuthi angangeni engqimbeni yokufakwa kwekhebula futhi kuqinisekiswe impilo yenkonzo yekhebula, ikhebula kufanele lisebenzise isakhiwo sengqimba yokuvimbela engangenisi i-radial, ehlanganisa i-sheath yensimbi kanye ne-metal-plastic sheath ehlanganisiwe. I-lead, ithusi, i-aluminium nezinye izinto zensimbi zivame ukusetshenziswa njenge-sheath yensimbi yezintambo; I-tape ehlanganisiwe yensimbi-plastiki kanye ne-polyethylene sheath yakha i-metal-plastic composite sheath yekhebula. I-metal-plastic composite sheath, eyaziwa nangokuthi i-comprehensive sheathing, ibonakala ngobumnene, ukuphatheka kalula, kanye nokuvuleka kwamanzi kuncane kakhulu kune-plastic, i-raber sheathing, efanelekile ezindaweni ezinezidingo eziphezulu zokusebenza okungangeni manzi, kodwa uma kuqhathaniswa ne-metal sheathing, i-metal-plastic sheathing ehlanganisiwe isene-permeability ethile.
Ezindinganisweni zekhebula le-voltage eliphakathi laseYurophu njenge-HD 620 S2: 2009, NF C33-226: 2016, UNE 211620: 2020, i-aluminium tape eboshwe ngepulasitiki eboshwe ngecala elilodwa isetshenziswa njengesimbozo esibanzi esingangeni manzi sezintambo zikagesi. Isendlalelo sensimbi sezinhlangothi ezimbiliiteyipu ye-aluminium ehlanganiswe ngepulasitikiithintana ngqo nesivikelo sokuvikela, futhi idlala indima yesivikelo sensimbi ngesikhathi esifanayo. Ngokwezinga laseYurophu, kuyadingeka ukuhlola amandla okuqhaqha phakathi kwetheyiphu ye-aluminium eboshwe ngepulasitiki kanye nesheya yekhebula bese kwenziwa izivivinyo zokumelana nokugqwala ukuze kulinganiswe ukumelana kwamanzi aqondile kwekhebula; Ngesikhathi esifanayo, kuyadingeka futhi ukukala ukumelana kwe-DC kwetheyiphu ye-aluminium eboshwe ngepulasitiki ukuze kulinganiswe ikhono layo lokuthwala ugesi wesifunda esifushane.
1. Ukuhlukaniswa kwetheyiphu ye-aluminium eboshwe ngepulasitiki
Ngokwenani elihlukile lefilimu yepulasitiki eboshwe ngezinto ze-aluminium substrate, ingahlukaniswa ngezinhlobo ezimbili zenqubo yokumboza ende: i-aluminium tape eboshwe ngepulasitiki enezinhlangothi ezimbili kanye ne-aluminium tape eboshwe ngepulasitiki enezinhlangothi eyodwa.
Ingqimba ephelele yokuvikela engangeni manzi futhi engangeni umswakama yezintambo zamandla ezimaphakathi neziphansi kanye nezintambo ze-optical ezakhiwe nge-aluminium tape eboshwe ngepulasitiki enezinhlangothi ezimbili kanye ne-polyethylene, i-polyolefin kanye nokunye ukubopha idlala indima yamanzi aqondile kanye ne-proof of moisture. I-aluminium tape eboshwe ngepulasitiki enezinhlangothi eyodwa isetshenziswa kakhulu ekuvikeleni izinsimbi zokuxhumana.
Kwezinye izindinganiso zaseYurophu, ngaphezu kokusetshenziswa njengesivikelo esibanzi esingangeni manzi, iteyipu ye-aluminium eboshwe ngepulasitiki enohlangothi olulodwa isetshenziswa njengesivikelo sensimbi sezintambo ze-voltage ephakathi, kanti ukuvikela iteyipu ye-aluminium kunezinzuzo ezisobala zezindleko uma kuqhathaniswa nokuvikela ngethusi.
2. Inqubo yokugoqa isikhathi eside yetheyiphu ye-aluminium eboshwe ngepulasitiki
Inqubo yokusonga ende ye-aluminium-plastic composite strip ibhekisela enqubweni yokuguqula i-aluminium coated tape yepulasitiki eboshwe kusuka esimweni sokuqala esiyisicaba kuya esimweni seshubhu ngochungechunge lokuguqulwa kwesikhunta, kanye nokubopha imiphetho emibili ye-aluminium coated tape yepulasitiki eboshwe. Imiphetho emibili ye-aluminium coated tape yepulasitiki eboshwe iyisicaba futhi ibushelelezi, imiphetho iboshwe ngokuqinile, futhi akukho ukuxebuka kwe-aluminium-plastic.
Inqubo yokushintsha i-aluminium tape eboshwe ngepulasitiki kusuka esimweni esiyisicaba kuya esimweni se-tubular ingafezwa ngokusebenzisa i-longitudinal wrapping die eyakhiwe i-longitudinal wrapping horn die, i-line stabilizing die kanye ne-sizeing die. Umdwebo wokugeleza kwe-longitudinal wrapping molding die ye-plastic coated aluminium tape uboniswe esithombeni esilandelayo. Imiphetho emibili ye-tubile plastic coated aluminium tape ingahlanganiswa ngezinqubo ezimbili: i-hot bonding kanye ne-cold bonding.
(1) Inqubo yokubopha okushisayo
Inqubo yokubopha ngokushisa iwukusebenzisa ungqimba lwepulasitiki lwetheyiphu ye-aluminium eboshwe ngepulasitiki ukuze ithambe ku-70~90℃. Enqubweni yokuguqulwa kwetheyiphu ye-aluminium eboshwe ngepulasitiki, ungqimba lwepulasitiki olusekuhlanganeni kwetheyiphu ye-aluminium eboshwe ngepulasitiki lufudunyezwa kusetshenziswa isibhamu somoya oshisayo noma ilangabi le-blowtorch, kanti imiphetho emibili yetheyiphu ye-aluminium eboshwe ngepulasitiki ihlanganiswa ndawonye kusetshenziswa i-viscosity ngemva kokuthamba kwesendlalelo sepulasitiki. Namathisela imiphetho emibili yetheyiphu ye-aluminium eboshwe ngepulasitiki ngokuqinile.
(2) Inqubo yokubopha okubandayo
Inqubo yokubopha okubandayo ihlukaniswe izinhlobo ezimbili, eyodwa iwukufaka i-die ende eqinile phakathi kwe-caliper die kanye nekhanda le-extruder, ukuze i-aluminium tape eboshwe ngepulasitiki igcine isakhiwo se-tubular esizinzile ngaphambi kokungena ekhanda le-extruder, ukuphuma kwe-stable die kuseduze nokuphuma kwe-die core ye-extruder, futhi i-aluminium-plastic composite ingena ngokushesha kwi-die core ye-extruder ngemva kokukhipha i-stable die. Ingcindezi ye-extrusion yezinto ze-sheath igcina isakhiwo se-tubular se-aluminium tape eboshwe ngepulasitiki, futhi izinga lokushisa eliphezulu le-extruded plastic lithambisa ungqimba lwepulasitiki lwe-aluminium tape eboshwe ngepulasitiki ukuze kuqedwe umsebenzi wokubopha. Lobu buchwepheshe bufanele i-aluminium tape eboshwe ngepulasitiki enezinhlangothi ezimbili, imishini yokukhiqiza ilula ukuyisebenzisa, kodwa ukucubungula isikhunta kuyinkimbinkimbi, futhi i-aluminium tape eboshwe ngepulasitiki kulula ukuyibuyisela emuva.
Enye inqubo yokubopha okubandayo ukusetshenziswa kokubopha okunamathelayo okuncibilikisiwe okushisayo, i-hot melt glue encibilikisiwe ngumshini wokukhipha endaweni yokubumba ye-longitudinal wrap horn ecindezelwe ohlangothini olulodwa lomphetho wangaphandle we-plastic coated aluminium tape, izikhundla ezimbili zomphetho we-plastic coated aluminium tape ngokusebenzisa umugqa ozinzile kanye nosayizi ofa ngemva kokubopha okunamathelayo okuncibilikisiwe okushisayo. Lobu buchwepheshe bufanele kokubili i-aluminium tape enamathelayo epulasitiki enezinhlangothi ezimbili kanye ne-aluminium tape enamathelayo epulasitiki enezinhlangothi eyodwa. Imishini yayo yokucubungula isikhunta kanye nokukhiqiza kulula ukuyisebenzisa, kodwa umphumela wayo wokubopha uthintwa kakhulu yikhwalithi ye-hot melt glue.
Ukuze kuqinisekiswe ukuthembeka kokusebenza kohlelo lwekhebula, isivikelo sensimbi kumele sixhunywe ngogesi nesivikelo sokushisa sekhebula, ngakho-ke i-aluminium tape enepulasitiki eboshwe ngohlangothi olulodwa kumele isetshenziswe njengesivikelo sensimbi sekhebula. Isibonelo, inqubo yokubopha okushisayo okukhulunywe ngayo kuleli phepha ifaneleka kuphela kuma-double-side.iteyipu ye-aluminium ehlanganiswe ngepulasitiki, kuyilapho inqubo yokubopha okubandayo esebenzisa inhlaka eshisayo yokuncibilika ifaneleka kakhulu kwitheyiphu ye-aluminium eboshwe ngepulasitiki enohlangothi olulodwa.
