Xa inkqubo yentambo ibekwe phantsi komhlaba, kwipaseji engaphantsi komhlaba okanye emanzini athambekele ekuqokeleleni amanzi, ukuze kuthintelwe umphunga wamanzi kunye namanzi ukuba angangeni kwi-cable insulation layer kunye nokuqinisekisa ubomi benkonzo yentambo, intambo kufuneka yamkele i-radial impervious barrier layer structure, ebandakanya i-sheath yesinyithi kunye ne-metal-plastic composite sheath. Ilothe, ubhedu, i-aluminiyam kunye nezinye izinto zetsimbi zisetyenziswa ngokuqhelekileyo njengeeshethi zetsimbi kwiintambo; I-tape ye-metal-plastic composite kunye ne-polyethylene sheath yenza i-metal-plastic composite sheath yekhebula. I-Metal-plastic composite sheathing, ekwabizwa ngokuba yi-sheathing ebanzi, ibonakala ngokuthamba, ukuphatheka, kunye nokungena kwamanzi kuncinci kakhulu kuneplastiki, i-rubber sheathing, ilungele iindawo ezineemfuno zokusebenza eziphezulu zokungena manzi, kodwa xa kuthelekiswa ne-sheathing yesinyithi, i-metal-plastic composite sheathing isenokungena okuthile.
Kwimigangatho yentambo yaseYurophu yamandla ombane aphakathi afana ne-HD 620 S2: 2009, NF C33-226: 2016, UNE 211620: 2020, i-tape yeplastiki ehlanganiswe neplastiki enecala elilodwa isetyenziswe njengesigqubuthelo esibanzi sokukhusela amanzi kwiintambo zamandla. Umaleko wesinyithi wecala elinyetape aluminiyam egqunywe ngeplastikiinxibelelana ngokuthe ngqo nekhaka le-insulating, kwaye idlala indima yentsimbi yentsimbi ngaxeshanye. Kwimigangatho yaseYurophu, kuyimfuneko ukuvavanya amandla okuhluba phakathi kweplastiki efakwe i-aluminium tape kunye ne-cable sheath kwaye wenze iimvavanyo zokuxhathisa ukubola ukulinganisa ukuxhathisa kwamanzi e-radial yentambo; Kwangaxeshanye, kukwayimfuneko ukulinganisa uxhathiso lwe-DC lweplastiki egqunywe nge-aluminium tape ukulinganisa amandla ayo okuthwala isiphaluka esifutshane sangoku.
1. Ukuhlelwa kwetape ye-aluminium ehlanganiswe ngeplastiki
Ngokwenani elahlukileyo lefilimu yeplastiki eqatywe nge-aluminiyam substrate imathiriyeli, inokwahlulwa ibe ziindidi ezimbini zenkqubo yokugquma i-longitudinal: iplastiki enamacala amabini agqunywe ngeteyiphu ye-aluminiyam kunye ne-aluminiyam enecala elinye.
Umaleko obanzi okhuselayo wokungangeni manzi kunye nobungqina bokufuma kobume bombane ophakathi kunye nophantsi kweentambo zamandla ombane kunye neentambo ze-optical ezenziwe ngeteyiphu ye-aluminiyam enamacala amabini kunye ne-polyethylene, i-polyolefin kunye nezinye i-sheathing zidlala indima yamanzi e-radial kunye nobungqina bokufuma. Iteyiphu yealuminiyam enecala elinye yeplastiki isetyenziswa ikakhulu ukukhusela isinyithi kwiintambo zonxibelelwano.
Kweminye imigangatho yaseYurophu, ukongeza ekusetyenzisweni njengesingxobo esibanzi sokungangeni manzi, iteyiphu yeplastiki enecala elinye egqunywe ngealuminium ikwasetyenziswa njengekhaka lesinyithi kwiintambo zombane ophakathi, kunye nokukhusela itheyiphu yealuminiyam kuneengenelo ezicacileyo zeendleko xa kuthelekiswa nokhuseleko lobhedu.
2. Inkqubo yokusonga i-longitudinal ye-tape ye-aluminiyam yeplastiki
Inkqubo yokusonga yobude bomcu we-aluminiyam-yeplastiki ibhekiselele kwinkqubo yokuguqula itheyiphu ye-aluminium egqunywe ngeplastiki ukusuka kwimilo ethe tyaba yoqobo ukuya kwimilo yetyhubhu ngothotho loguqulo lokungunda, kunye nokubopha imiphetho emibini yeteyiphu ye-aluminiyam egqunywe ngeplastiki. Imiphetho emibini yeplastiki efakwe i-aluminium tape ilula kwaye igudileyo, imiphetho ibotshelelwe ngokuqinileyo, kwaye akukho aluminium-iplastiki ye-peeling.
Inkqubo yokutshintsha iteyiphu ye-aluminium egqunywe ngeplastiki ukusuka kwimilo ecaba ukuya kwimilo ye-tubular inokuqondwa ngokusebenzisa i-longitudinal yokusonga idayiti eyenziwe ngophondo lokusonga longitudinal, umgca wokuzinzisa ukufa kunye nokulinganisa ukufa. Umzobo ojikelezayo we-longitudinal ukugoqa ukubumba i-tape yeplastiki egqunywe nge-aluminium iboniswe kulo mfanekiso ulandelayo. Imiphetho emibini yeplastiki ye-tubula yeplastiki ene-aluminium tape inokudityaniswa ngeenkqubo ezimbini: ukudibanisa okutshisayo kunye nokubanda okubandayo.
(1) Inkqubo yokudibanisa eshushu
Inkqubo yokudibanisa i-thermal kukusebenzisa umaleko weplastiki we-tape ye-aluminium egqunywe ngeplastiki ukuthamba kwi-70 ~ 90 ℃. Kwinkqubo yokuguqulwa kweteyiphu ye-aluminium egqunywe ngeplastiki, umaleko weplastiki ekudibaneni kweteyiphu ye-aluminium egqunywe ngeplastiki iyafudunyezwa kusetyenziswa umpu womoya oshushu okanye i-bloodtorch flame, kwaye imiphetho emibini yeteyiphu ye-aluminiyam egqunywe ngeplastiki idityaniswe kunye kusetyenziswa i-viscosity emva kokuthamba kocweyo lweplastiki. Ncamathelisa imiphetho yomibini yeteyiphu yealuminiyam yeplastiki eqatywe ngokuqinileyo.
(2) Inkqubo yokubambisana ebandayo
Inkqubo yokudibanisa ebandayo yahlulwe ibe ziindidi ezimbini, enye kukongeza ukufa okuzinzileyo phakathi kwecaliper die kunye nentloko ye-extruder, ukuze iteyiphu ye-aluminium egqunywe ngeplastiki igcine isakhiwo se-tubular esizinzile ngaphambi kokungena kwentloko ye-extruder, ukuphuma kwi-stable die isondele ekuphumeni kwe-extruder kunye ne-diyelumini ye-diyelumini ye-diesocore ngoko nangoko. I-extruder's die core emva kokuthatha i-stable die. Uxinzelelo lwe-extrusion ye-sheath material igcina isakhiwo se-tubular ye-tape ye-aluminium egqunywe ngeplastiki, kunye nobushushu obuphezulu beplastiki ekhutshiweyo buthambisa iplastiki yeplastiki ehlanganiswe ne-aluminium tape ukugqiba umsebenzi wokudibanisa. Le teknoloji ifanelekile kwiteyiphu yeplastiki elayitiweyo ephindwe kabini ehlanganiswe nge-aluminium, izixhobo zemveliso zilula ukusebenza, kodwa ukusetyenzwa komngundo kunzima, kwaye i-tape ye-aluminiyam egqunywe ngeplastiki kulula ukuyibuyisela.
Enye inkqubo yokudibanisa ebandayo kukusetyenziswa kokuncamathelisa okutshisayo okunyibilikayo, incatho encamathelayo eshushu inyibilikiswa ngumatshini wokukhupha kwindawo yokubumba uphondo olude oludityanisiweyo kwicala elinye lomphetho weteyiphu ye-aluminium egqunywe ngeplastiki, iindawo ezimbini zomphetho weteyiphu yeplastiki egqunywe nge-aluminiyam ngentambo emva komgca wokubambelela kunye nokulinganisa i-diet. Le teknoloji ifanelekile kwiteyiphu ye-aluminiyam enamacala amabini eplastiki kunye neplastiki enecala elinye egqunywe nge-aluminiyam tape. Ukusetyenzwa kwayo kunye nezixhobo zokuvelisa kulula ukusebenza, kodwa umphumo wayo wokudibanisa uchaphazeleka kakhulu kumgangatho wokunamathelisa okutshisa okunyibilikayo.
Ukuze kuqinisekiswe ukuthembeka kokusebenza kwenkqubo yentambo, isikhuselo sesinyithi kufuneka sidibaniswe ngombane kunye nesikhuselo se-insulation yentambo, ngoko ke i-tape ye-aluminium enecala elilodwa kufuneka isetyenziswe njengekhaka lensimbi yekhebula. Ngokomzekelo, inkqubo yokudibanisa eshushu ekhankanywe kweli phepha ifanelekile kuphela kumacala amabinitape aluminiyam egqunywe ngeplastiki, ngelixa inkqubo yokudibanisa ebandayo usebenzisa i-adhesive eshushu enyibilikayo ifaneleka ngakumbi kwi-tape ye-aluminiyam yeplastiki enecala elinye.
