Xa inkqubo yekhebula ibekwe phantsi komhlaba, kwindawo engaphantsi komhlaba okanye emanzini anokuthi aqokelele amanzi, ukuze kuthintelwe umphunga wamanzi namanzi ukuba angangeni kumaleko wokugquma ikhebula kwaye kuqinisekiswe ubomi benkonzo yekhebula, ikhebula kufuneka lisebenzise isakhiwo somaleko othintelo olungena kwi-radial, oluquka ishelufu yesinyithi kunye neshelufu yentsimbi-plastiki. I-lead, ubhedu, i-aluminium kunye nezinye izinto zesinyithi zihlala zisetyenziswa njengeeshelufu zesinyithi kwiintambo; Iteyiphu yentsimbi-plastiki kunye neshelufu ye-polyethylene zenza ishelufu yentsimbi-plastiki edibeneyo yentambo. Ishelufu yentsimbi-plastiki edibeneyo, eyaziwa ngokuba yishelufu epheleleyo, ibonakaliswa bubuthambile, ukuthwaleka, kwaye ukuvuleka kwamanzi kuncinci kakhulu kuneplastiki, ishelufu yerabha, efanelekileyo kwiindawo ezineemfuno eziphezulu zokusebenza okungangeni manzi, kodwa xa kuthelekiswa neshelufu yesinyithi, ishelufu yentsimbi-plastiki edibeneyo isenokungena okuthile.
Kwimigangatho yekhebula le-voltage ephakathi yaseYurophu efana ne-HD 620 S2: 2009, NF C33-226: 2016, UNE 211620: 2020, iteyiphu ye-aluminium egqunywe ngeplastiki enecala elinye isetyenziswa njengesigqubuthelo esibanzi esingangeni manzi kwiintambo zombane. Umaleko wesinyithi wecala elinyeiteyiphu ye-aluminium egqunywe ngeplastikiidibana ngqo nesikhuselo sokukhusela, kwaye idlala indima yesikhuselo sesinyithi ngaxeshanye. Kwimigangatho yaseYurophu, kuyimfuneko ukuvavanya amandla okuqhawula phakathi kweteyiphu ye-aluminium egqunywe ngeplastiki kunye nesheya yentambo kwaye kwenziwe uvavanyo lokumelana nokugqwala ukulinganisa ukumelana kwamanzi e-radial yentambo; Kwangaxeshanye, kuyimfuneko ukulinganisa ukumelana kwe-DC kweteyiphu ye-aluminium egqunywe ngeplastiki ukulinganisa amandla ayo okuthwala umsinga wesekethe emfutshane.
1. Udidi lweteyiphu ye-aluminium egqunywe ngeplastiki
Ngokwenani elahlukileyo lefilimu yeplastiki egqunywe ngezinto ze-aluminium substrate, inokwahlulwa ibe ziintlobo ezimbini zenkqubo yokugquma ende: iteyiphu ye-aluminium egqunywe ngeplastiki enamacala amabini kunye neteyiphu ye-aluminium egqunywe ngeplastiki enye.
Umaleko okhuselekileyo obanzi ongangeni manzi nongangeni manzi weentambo zamandla eziphakathi nezisezantsi kunye neentambo ze-optical ezenziwe ngeteyiphu ye-aluminium efakwe iplastiki kunye ne-polyethylene, i-polyolefin kunye nezinye izigqubuthelo zidlala indima yamanzi e-radial kunye nongangeni manzi. Iteyiphu ye-aluminium efakwe iplastiki enye isetyenziswa kakhulu ekukhuseleni iintambo zonxibelelwano ngesinyithi.
Kweminye imigangatho yaseYurophu, ukongeza ekusetyenzisweni njengeshelufu ebanzi engangeni manzi, iteyiphu ye-aluminium egqunywe ngeplastiki enecala elinye ikwasetyenziswa njengesikhuselo sesinyithi kwiintambo ze-voltage ephakathi, kwaye isikhuselo seteyiphu ye-aluminium sineengenelo ezicacileyo zexabiso xa kuthelekiswa nesikhuselo sobhedu.
2. Inkqubo yokusonga i-longitudinal yeteyiphu ye-aluminium egqunywe ngeplastiki
Inkqubo yokusonga ende ye-aluminium-plastic composite strip ibhekisa kwinkqubo yokuguqula iteyiphu ye-aluminium egqunywe ngeplastiki ukusuka kwimo yokuqala ethe tyaba ukuya kwimo yetyhubhu ngothotho lokuguqulwa kwesikhunta, kunye nokubopha imiphetho emibini yeteyiphu ye-aluminium egqunywe ngeplastiki. Imiphetho emibini yeteyiphu ye-aluminium egqunywe ngeplastiki ithe tyaba kwaye igudile, imiphetho ibotshelelwe ngokuqinileyo, kwaye akukho kuxobuka kwe-aluminium-plastic.
Inkqubo yokutshintsha iteyiphu ye-aluminium egqunywe ngeplastiki ukusuka kwimilo ethe tyaba ukuya kwimilo yetyhubhu inokufezekiswa ngokusebenzisa i-longitudinal wrapping die eyenziwe yi-longitudinal wrapping horn die, i-line stabilizing die kunye ne-sizeing die. Umzobo wokuhamba kwe-longitudinal wrapping molding die yeteyiphu ye-aluminium egqunywe ngeplastiki uboniswe kumfanekiso olandelayo. Imiphetho emibini yeteyiphu ye-aluminium egqunywe ngeplastiki yetyhubhu inokudityaniswa ngeenkqubo ezimbini: i-hot bonding kunye ne-cold bonding.
(1) Inkqubo yokubopha eshushu
Inkqubo yokubopha ngobushushu kukusebenzisa umaleko weplastiki weteyiphu ye-aluminiyam egqunywe ngeplastiki ukuze ithambise kwi-70~90℃. Kwinkqubo yokuguqulwa kweteyiphu ye-aluminiyam egqunywe ngeplastiki, umaleko weplastiki kwindawo edibeneyo yeteyiphu ye-aluminiyam egqunywe ngeplastiki ufudunyezwa kusetyenziswa isibhamu somoya oshushu okanye ilangabi le-blowtorch, kwaye imiphetho emibini yeteyiphu ye-aluminiyam egqunywe ngeplastiki idityaniswa kunye kusetyenziswa i-viscosity emva kokuthamba komaleko weplastiki. Ncamathisela imiphetho emibini yeteyiphu ye-aluminiyam egqunywe ngeplastiki ngokuqinileyo.
(2) Inkqubo yokubopha ebandayo
Inkqubo yokubopha ebandayo yahlulwe yangamabini, enye kukongeza i-die ende ezinzileyo phakathi kwe-caliper die kunye nentloko ye-extruder, ukuze iteyiphu ye-aluminium egqunywe ngeplastiki igcine isakhiwo se-tubular esizinzileyo ngaphambi kokuba ingene entlokweni ye-extruder, ukuphuma kwe-die ezinzileyo kusondele ekuphumeni kwe-die core ye-extruder, kwaye i-aluminium-plastic composite ingena kwangoko kwi-die core ye-extruder emva kokukhupha i-die ezinzileyo. Uxinzelelo lwe-extrusion lwezinto ze-sheath lugcina isakhiwo se-tubular seteyiphu ye-aluminium egqunywe ngeplastiki, kwaye ubushushu obuphezulu beplastiki eqhunyiweyo buthambisa umaleko weplastiki weteyiphu ye-aluminium egqunywe ngeplastiki ukuze kugqitywe umsebenzi we-bonding. Le teknoloji ifanelekile kwiteyiphu ye-aluminium egqunywe ngeplastiki enamacala amabini, izixhobo zemveliso zilula ukuzisebenzisa, kodwa ukucutshungulwa kwe-mold kuyinkimbinkimbi, kwaye iteyiphu ye-aluminium egqunywe ngeplastiki kulula ukuyibuyisela.
Enye inkqubo yokubopha ebandayo kukusetyenziswa kwe-hot melt adhesive bonding, i-hot melt adhesive enyibilikisiweyo ngumatshini wokukhupha kwindawo yokubumba ye-longitudinal wrap horn ecinezelwe kwicala elinye lomphetho wangaphandle weteyipu ye-aluminium egqunywe ngeplastiki, iindawo ezimbini zomphetho weteyipu ye-aluminium egqunywe ngeplastiki ngokusebenzisa umgca ozinzileyo kunye nobukhulu bokufa emva kwe-hot melt adhesive bonding. Le teknoloji ifanelekile kuzo zombini iteyipu ye-aluminium egqunywe ngeplastiki ephindwe kabini kunye neteyipu ye-aluminium egqunywe ngeplastiki eqwengiweyo ...
Ukuze kuqinisekiswe ukuthembeka kokusebenza kwenkqubo yekhebula, ikhaka lesinyithi kufuneka lidityaniswe ngombane nesikhuselo sokukhusela intambo, ngoko ke iteyiphu ye-aluminium egqunywe ngeplastiki enecala elinye mayisetyenziswe njengesikhuselo sesinyithi sentambo. Umzekelo, inkqubo yokubopha eshushu ekhankanyiweyo kweli phepha ifanelekile kuphela kwiicala ezimbini.iteyiphu ye-aluminium egqunywe ngeplastiki, ngelixa inkqubo yokubopha ebandayo esebenzisa iglu eshushu yokunyibilika ifanelekile ngakumbi kwiteyiphu ye-aluminium egqunywe ngeplastiki enecala elinye.
