Ibhantshi lekhebula liwungqimba olungaphandle kakhulu lwekhebula.Isebenza njengesithiyo esibaluleke kakhulu kukhebula ukuvikela ukuphepha kwesakhiwo sangaphakathi futhi ivikela ikhebula ekulimaleni komshini ngesikhathi nangemva kokufakwa.Amabhantshi ekhebula awahloselwe ukushintsha isivikelo esiqinisiwe ngaphakathi kwekhebula, kodwa anganikeza izinga eliphezulu, noma lilinganiselwe, izindlela zokuvikela.Ukwengeza, amajakhethi ekhebula anikeza isivikelo kumswakama, amakhemikhali, imisebe ye-UV, ne-ozone.Ngakho-ke, yiziphi izinto ezisetshenziselwa ukushefa kwekhebula?
1. Izinto ze-cable sheath: I-PVC
Izinto zekhebula ziyizinhlayiya ezilungiselelwe ngokuxuba, ukuxova kanye nokukhipha i-polyvinyl chloride njengesisekelo se-resin, ukwengeza ama-stabilizers, ama-plasticizers, ama-inorganic fillers afana ne-calcium carbonate, ama-axiliaries kanye nezinto zokugcoba.
I-PVC ingenziwa ukuze isetshenziswe ezindaweni ezihlukahlukene kanye nezinhlelo zokusebenza.Kushibhile ukukusebenzisa, kuyavumelana nezimo, kunamandla ngokwenele, futhi kunezinto ezimelana nomlilo/uwoyela.
Kodwa-ke, le nto iqukethe izinto eziyingozi emvelweni nasemzimbeni womuntu, futhi kunezinkinga eziningi lapho isetshenziswa ezindaweni ezikhethekile.Ngokuthuthukiswa kokuqwashisa kwabantu ngemvelo kanye nokuthuthukiswa kwezidingo zokusebenza kwezinto ezibonakalayo, izidingo eziphakeme ziye zabekwa phambili zezinto ze-PVC.
2. Impahla ye-cable sheath: PE
Ngenxa yezakhiwo zayo ezinhle kakhulu zokuvikela ugesi kanye nezakhiwo ezinhle zokucubungula, i-polyethylene isetshenziswa kabanzi njengento yokumboza izintambo nezintambo, futhi isetshenziswa kakhulu ungqimba lwe-insulation kanye ne-sheath layer yezintambo nezintambo.
Izakhiwo zikagesi ezinhle kakhulu kanye nokumelana nokufakwa okuphezulu kakhulu.I-polyethylene ingaba lukhuni futhi iqine kakhulu, kodwa i-PE (LDPE) enezinga eliphansi ivumelana nezimo futhi imelana kakhulu nomswakama.I-PE eyakhiwe kahle inokumelana nesimo sezulu esihle kakhulu.
Isakhiwo samangqamuzana esiqondile se-polyethylene senza kube lula ukukhubazeka emazingeni okushisa aphezulu.Ngakho-ke, ekusetshenzisweni kwe-PE embonini yocingo nekhebula, i-polyethylene ivame ukuxhunyaniswa nesakhiwo senethiwekhi, okwenza ukuthi imelane kakhulu nokushisa okuphezulu.Ukumelana ne-deformation.
I-Cross-linked polyethylene (XLPE) kanye ne-polyvinyl chloride (PVC) zombili zisetshenziswa njengezinto zokufakelwa kwezintambo nezintambo, kodwa izintambo nezintambo ze-XLPE zinobungani bemvelo kunezintambo nezintambo ze-PVC futhi zisebenza kangcono.
3.Impahla ye-cable sheath: PUR
Ikhebula le-PUR wuhlobo olulodwa lwekhebula.Izinto zekhebula le-PUR zinezinzuzo zokumelana nowoyela nokumelana nokugqoka, kuyilapho i-PVC yenziwe ngezinto ezijwayelekile.Embonini yamakhebula eminyakeni embalwa edlule, i-polyurethane ibaluleke kakhulu.Ezingeni elithile lokushisa, izakhiwo zemishini zifana nerabha.Inhlanganisela ye-thermoplasticity ne-elasticity iphumela ku-TPE thermoplastic elastomer.
Isetshenziswa kakhulu emishinini yezimboni kanye nemishini, izinhlelo zokulawula ukudlulisa, izinzwa ezahlukahlukene zezimboni, amathuluzi okuhlola, izinto zikagesi, izinto zikagesi zasendlini, i-electromechanical, ikhishi kanye nezinye izinto zokusebenza, futhi isetshenziselwa ukuphakelwa kukagesi nokuxhuma amasignali ezindaweni ezinokhahlo, ukuvikela uwoyela. nezinye izikhathi.
4. Izinto ze-cable sheath: TPE/TPR
Ama-thermoplastic elastomers ahlinzeka ngezakhiwo ezinhle kakhulu zezinga lokushisa eliphansi ngaphandle kwezindleko zama-thermosets.Inokumelana okuhle kwamakhemikhali namafutha futhi iguquguquka kakhulu.Ukumelana nokugqokwa okuhle nokuthungwa kwendawo, kodwa hhayi okuqinile njenge-PUR.
5. Impahla ye-cable sheath: TPU
Intambo ye-polyurethane ibhekisela kukhebula esebenzisa impahla ye-polyurethane njenge-insulation noma i-sheath.Ukumelana kwayo nokugqoka okuphezulu kubhekisela ekuphikisweni okukhulu kokugqoka kweshethi yekhebula kanye nongqimba lwe-insulation.Impahla ye-polyurethane esetshenziswa kuzintambo, evame ukubizwa nge-TPU, iyirabha ye-thermoplastic polyurethane elastomer.Ihlukaniswe kakhulu ngohlobo lwe-polyester nohlobo lwe-polyether, enobubanzi bokuqina (60HA-85HD), ukumelana nokugqoka, ukumelana nowoyela, ukucaca, nokunwebeka okuhle.I-TPU ayinakho nje kuphela ukuthi inokumelana nokugqokwa okuphezulu okuhle kakhulu, ukushuba okuphezulu, amandla aqine kakhulu, ukuqina futhi Inokumelana nokuguga futhi iyinto evuthiwe evumelana nemvelo.
Izindawo ezisetshenziswayo zamakhebuli aneshehethi enziwe nge-polyurethane zihlanganisa izintambo zokufaka isicelo zasolwandle, irobhothi lezimboni kanye nezintambo zokukhohlisa, imishini yasechwebeni kanye nezintambo ze-gantry crane drum, kanye nezintambo zemishini yobunjiniyela bezimayini.
6. Izinto ze-cable sheath: I-Thermoplastic CPE
I-Chlorinated polyethylene (CPE) ivame ukusetshenziswa ezindaweni ezinzima kakhulu.Inezici zesisindo esilula, ezinzima kakhulu, i-coefficient ephansi ye-friction, ukumelana kahle nowoyela, ukumelana kahle kwamanzi, ukumelana okuhle kakhulu kwamakhemikhali nokumelana ne-UV, nezindleko eziphansi.
7. Izinto ze-cable sheath: irabha ye-ceramic silicone
Irabha ye-ceramic silicone inokuvikela umlilo okuhle kakhulu, i-flame retardant, intuthu ephansi, engeyona enobuthi nezinye izakhiwo.Inqubo yokubumba i-extrusion ilula.Okusele ngemva kokushiswa yigobolondo le-ceramic eliqinile.Igobolondo eliqinile alincibiliki endaweni yomlilo futhi alidonsi, lingaphumelela ukuhlolwa kobuqotho bomugqa okucaciswe ku-GB/T19216.21-2003 ezingeni lokushisa elingu-950℃-1000℃, livezwe emlilweni imizuzu engama-90, futhi selipholile. imizuzu engu-15.Ifanele noma iyiphi indawo edinga ukuvikelwa komlilo ukuze kuqinisekiswe ukudluliswa kwamandla okubushelelezi uma kwenzeka umlilo.Yadlala indima eqinile yokuvikela.
Imikhiqizo yerabha ye-ceramic silicone ayinazo izidingo ezikhethekile zemishini futhi ubuchwepheshe bokucubungula bulula.Ukukhiqizwa kungafinyelelwa kusetshenziswa imishini yokucubungula irabha ye-silicone yendabuko.Uma kuqhathaniswa nobuchwepheshe bamanje bokukhiqiza izintambo zezintambo kanye nekhebula, inokukhiqiza okuphezulu okuphumelelayo futhi inganciphisa ukusetshenziswa kwamandla okukhiqiza futhi yonge izindleko.
Okungenhla kumayelana nezinto zekhebula sheath.Eqinisweni, kunezinhlobo eziningi zezintambo zekhebula.Lapho ukhetha izinto zokusetshenziswa zamashethi ekhebula, ukuhambisana kwesixhumi nokuvumelana nezimo endaweni kufanele kucatshangelwe.Isibonelo, izindawo ezibanda kakhulu zingadinga ukumbozwa ngekhebula okuhlala kuvumelana nezimo emazingeni okushisa aphansi kakhulu.
