Xa inkqubo yentambo ibekwe phantsi komhlaba, kwindlela engaphantsi komhlaba okanye emanzini athambekele ekuqokeleleni amanzi, ukuze kuthintelwe umphunga wamanzi kunye namanzi ekungeneni kwinqanaba lokufakelwa kwentambo kunye nokuqinisekisa ubomi benkonzo yentambo, intambo kufuneka yamkele umphunga wamanzi kunye namanzi. ubume be-radial obungenakuthintelwa, obubandakanya 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, ekwaziwa ngokuba yi-comprehensive sheathing, ibonakala ngokuthamba, ukuphatheka, kunye nokungena kwamanzi kuncinci kakhulu kuneplastiki, i-rubber sheathing, ilungele iindawo ezineemfuno zokusebenza eziphezulu zokungangeni kwamanzi, kodwa xa kuthelekiswa nesinyithi, i-metal-plastic composite. I-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 wrapping molding die of the tape yeplastiki egqunywe nge-aluminium iboniswe kulo mzobo ulandelayo. Imiphetho emibini ye-tubula yeplastiki efakwe kwi-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-aluminiyam egqunywe ngeplastiki, umaleko weplastiki ekudityanisweni kweteyiphu ye-aluminium egqunywe ngeplastiki iyafudunyezwa kusetyenziswa umpu womoya oshushu okanye i-blowtorch flame, kwaye imiphetho emibini yeteyiphu ye-aluminium egqunywe ngeplastiki idityaniswe kunye kusetyenziswa i-viscosity. emva kokuthamba komgangatho weplastiki. Ncamathelisa imiphetho yomibini yeteyiphu yealuminiyam yeplastiki eqatywe ngokuqinileyo.
(2) Inkqubo yokubambisana ebandayo
Inkqubo yokudibanisa ebandayo yahlulwe ibe ziindidi ezimbini, enye kukudibanisa ukufa okude okuzinzile phakathi kwecaliper die kunye nentloko ye-extruder, ukuze i-tape ye-aluminium egqunywe ngeplastiki igcine isakhiwo se-tubular esizinzileyo ngaphambi kokungena entloko ye-extruder. , ukuphuma kwe-stable die kufutshane ne-extruder's die core, kunye ne-aluminium-plastic composite ngokukhawuleza ingena kwi-core 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 kwe-adhesive eshushu enyibilikayo encamathelayo, incatho encamathelayo eshushu enyibilikayo enyibilikiswa ngumatshini wokukhutshwa kwindawo yokubumba uphondo longitudinal icinezelwe kwelinye icala lomphetho ongaphandle weteyiphu ye-aluminium egqunywe ngeplastiki, iindawo ezimbini zomphetho weplastiki. itheyiphu yealuminiyam egqunywe ngomgca ozinzileyo kunye nesizing iyafa emva kokunyibilika okunamathelisa okuncamathelayo. 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 isebenzisa i-adhesive eshushu enyibilikayo ifaneleka ngakumbi kwi-tape yeplastiki enecala elinye eligqunywe nge-aluminium.
