Ibhatyi yekhebula ngumaleko ongaphandle wentambo.Isebenza njengomqobo obaluleke kakhulu kwikhebula ukukhusela ukhuseleko lwesakhiwo sangaphakathi kunye nokukhusela ikhebula kumonakalo womatshini ngexesha nangemva kokufakela.Iibhatyi zekhebula azenzelwanga ukuba zithathe indawo yesikrweqe esomeleziweyo ngaphakathi kwentambo, kodwa zinokubonelela ngenqanaba eliphezulu ngokufanelekileyo, nangona lilinganiselwe, iindlela zokukhusela.Ukongeza, iibhatyi zentambo zibonelela ngokhuseleko kumswakama, iikhemikhali, imitha ye-UV kunye ne-ozone.Ke, zeziphi izinto ezisetyenziselwa ukucheba intambo?
1. Izinto ze-cable sheath: I-PVC
Izixhobo zekhebula ngamasuntswana alungiselelwe ngokuxuba, ukuxova kunye nokukhupha i-polyvinyl chloride njengesiseko se-resin, engeza i-stabilizers, i-plasticizers, i-inorganic fillers efana ne-calcium carbonate, i-axiliaries kunye ne-lubricants.
I-PVC inokuqulunqwa ukuze isetyenziswe kwiindawo ezahlukeneyo kunye nokusetyenziswa.Kutshiphu ukuyisebenzisa, ibhetyebhetye, yomelele ngokufanelekileyo, kwaye inezixhobo ezikwaziyo ukumelana nomlilo/i-oyile.
Nangona kunjalo, le nto iqulethe izinto ezinobungozi kwindalo kunye nomzimba womntu, kwaye kukho iingxaki ezininzi xa zisetyenziswe kwiindawo ezikhethekileyo.Ngokwandiswa kolwazi lwabantu ngokusingqongileyo kunye nokuphuculwa kweemfuno zokusebenza kwezinto, iimfuno eziphezulu ziye zabekwa phambili kwizinto zePVC.
2. Imathiriyeli ye-cable sheath: PE
Ngenxa yeempawu zayo zokugquma umbane ezigqwesileyo kunye neepropathi ezilungileyo zokusetyenzwa, i-polyethylene isetyenziswa ngokubanzi njengesixhobo sokugquma iingcingo kunye neentambo, kwaye isetyenziswa ikakhulu kwi-insulation layer kunye ne-sheath layer yeengcingo kunye neentambo.
Iipropathi zombane ezigqwesileyo kunye nokuxhathisa okuphezulu kakhulu kwe-insulation.I-Polyethylene inokuba nzima kwaye iqine kakhulu, kodwa i-PE (LDPE) yoxinaniso oluphantsi lubhetyebhetye kwaye luxhathisa ngokugqithisileyo kubumanzi.I-PE eyenziwe ngokufanelekileyo inokumelana nemozulu ebalaseleyo.
Isakhiwo se-molecular linear ye-polyethylene yenza kube lula ukuguquka kumaqondo aphezulu.Ngoko ke, kwizicelo ze-PE kwishishini lecingo kunye nentambo, i-polyethylene idla ngokudibanisa kwisakhiwo sothungelwano, okwenza ukuba ixhathise kakhulu kumaqondo okushisa aphezulu.Ukuchasana nokuguqulwa.
I-Cross-linked polyethylene (XLPE) kunye ne-polyvinyl chloride (PVC) zombini zisetyenziswa njengezinto zokugquma iingcingo kunye neentambo, kodwa iingcingo ze-XLPE kunye neentambo zihambelana nokusingqongileyo ngaphezu kweengcingo zePVC kunye neentambo kwaye zisebenza ngcono.
3.Impahla ye-cable sheath: PUR
Intambo yePUR yolunye uhlobo lwentambo.Izinto eziphathekayo ze-PUR cable zineenzuzo zokuchasana kweoli kunye nokuxhatshazwa kokugqoka, ngelixa i-PVC yenziwe ngezinto eziqhelekileyo.Kwishishini lekhebula kwiminyaka embalwa edlulileyo, i-polyurethane ibaluleke kakhulu.Kwiqondo lokushisa elithile, izinto eziphathekayo zezixhobo zifana nerubha.Indibaniselwano ye-thermoplasticity kunye ne-elasticity iphumela kwi-TPE thermoplastic elastomer.
Isetyenziswa ngokubanzi koomatshini bemizi-mveliso kunye nezixhobo, iinkqubo zolawulo lothumelo, izinzwa ezahlukeneyo zoshishino, izixhobo zokuvavanya, izixhobo zombane, izixhobo zasekhaya, i-electromechanical, ikhitshi kunye nezinye izixhobo, kwaye isetyenziselwa ukubonelela ngombane kunye noqhagamshelo lomqondiso kwiindawo ezinzima, ubungqina be-oyile. kunye namanye amaxesha.
4. Izinto ze-cable sheath: TPE / TPR
I-Thermoplastic elastomers ibonelela ngeempawu ezintle zobushushu obuphantsi ngaphandle kweendleko ze-thermosets.Inokumelana neekhemikhali kunye neoyile kwaye iguquguquka kakhulu.Ukumelana nokunxiba okufanelekileyo kunye nokuthungwa komphezulu, kodwa akuhlalanga njenge-PUR.
5. Izinto ze-cable sheath: TPU
Intambo yepolyurethane ibhekisa kwintambo esebenzisa imathiriyeli ye-polyurethane njenge-insulation okanye i-sheath.Ukumelana kwayo nokunxiba okuphezulu kubhekiselele kukumelana okuphezulu kwe-cable sheath kunye ne-insulation layer.Izinto zepolyurethane ezisetyenziswa kwiintambo, ezaziwa ngokuba yiTPU, yirabha ye-thermoplastic polyurethane elastomer.Ikakhulu yahlulwe ngohlobo lwe-polyester kunye nohlobo lwe-polyether, kunye noluhlu lobunzima (60HA-85HD), ukuxhathisa ukunxiba, ukuxhathisa ioli, ukucaca, kunye nokunwebeka okulungileyo.I-TPU ayinakukwazi ukumelana nokunxiba okuphezulu kuphela, ukuxinezeleka okuphezulu, ukomelela okuphezulu, ukuqina kwaye inokumelana nokwaluphala kwaye iyimathiriyeli ekhulileyo ehambelana nokusingqongileyo.
Iindawo ekusetyenzwa kuzo iintambo ze-polyurethane sheathed zibandakanya iintambo zosetyenziso lwaselwandle, iintambo zerobhothi zamashishini kunye neentambo ze-manipulator, oomatshini bezibuko kunye neentambo ze-gantry crane drum, kunye neentambo zobunjineli bobunjineli bemigodi.
6. Izinto ze-cable sheath: I-Thermoplastic CPE
I-Chlorinated polyethylene (CPE) isoloko isetyenziswa kwiindawo ezinzima kakhulu.Ineempawu zobunzima obulula, nzima kakhulu, i-coefficient ephantsi ye-friction, ukumelana ne-oyile elungileyo, ukuxhathisa okulungileyo kwamanzi, ukuchasana kweekhemikhali okugqwesileyo kunye nokuxhathisa kwe-UV, kunye neendleko eziphantsi.
7. Izinto ze-cable sheath: irabha ye-ceramic silicone
Irabha ye-silicone ye-ceramic inokhuseleko oluhle kakhulu lomlilo, i-flame retardant, umsi ophantsi, i-non-toxic kunye nezinye iimpawu.Inkqubo yokubumba i-extrusion ilula.Intsalela emva kokutshisa iqokobhe le-ceramic eliqinileyo.Igobolondo enzima ayinyibiliki kwindawo yomlilo kwaye ayilahlayo, inokudlula uvavanyo lwengqibelelo yomgca echazwe kwi-GB/T19216.21-2003 kwiqondo lokushisa le-950℃-1000℃, evezwe emlilweni imizuzu engama-90, kwaye ipholile. imizuzu eli-15.Ifanelekile nayiphi na indawo efuna ukukhuselwa komlilo ukuze kuqinisekiswe ukuhanjiswa kwamandla agudileyo xa kwenzeka umlilo.Idlale indima eyomeleleyo yokukhusela.
Iimveliso zerabha ye-silicone ye-ceramic ayinazo iimfuno ezikhethekileyo zezixhobo kwaye iteknoloji yokucubungula ilula.Ukuveliswa kunokufezekiswa kusetyenziswa izixhobo zokulungisa irabha ye-silicone.Xa kuthelekiswa neteknoloji yokuvelisa i-refractory kunye ne-cable, inomsebenzi ophezulu wemveliso kwaye inokunciphisa ukusetyenziswa kwamandla okuvelisa kunye nokugcina iindleko.
Oku ngasentla konke malunga nemathiriyeli ye-cable sheaths.Enyanisweni, zininzi iintlobo zeeshethi zekhebula.Xa ukhetha izinto eziluhlaza kwi-cable sheaths, ukuhambelana kwekhonkco kunye nokulungelelaniswa nokusingqongileyo kufuneka kuthathelwe ingqalelo.Umzekelo, iindawo ezibanda kakhulu zinokufuna intambo yebhatyi ehlala ibhetyebhetye kumaqondo obushushu aphantsi kakhulu.
