Unolwazi olungakanani ngeentambo ze-polyurethane? (Intambo ye-TPU)
Intambo yePolyurethaneIintambo ezisebenzisa izinto ze-polyurethane njenge-insulation okanye i-sheath. Ukumelana kwazo nokuguguleka okukhulu kubhekisa ekuxhathiseni ukuguguleka okukhulu kwe-cable sheath kunye nomaleko we-insulation.
Izinto ze-polyurethane ezisetyenziswa kwiintambo zihlala zibizwa ngokuba yi-TPU, eyirabha ye-thermoplastic polyurethane elastomer. Yahlulwe ngokubanzi ngohlobo lwe-polyester kunye nohlobo lwe-polyester, enoluhlu lobunzima (60HA-85HD), enganyangekiyo, enganyangekiyo ngeoyile, ecacileyo kunye ne-elastic. I-TPU ayinazo nje kuphela iimpawu ezibalaseleyo ezinganyangekiyo, ezinganyangekiyo, ezinganyangekiyo, ezomeleleyo nezingagugiyo, kodwa ikwayimpahla evuthiweyo enobuhlobo nokusingqongileyo.
Namhlanje, iLansheng Cable iza kukubonisa iimpawu eziphambili ezisi-8 kunye neendawo zokusetyenziswa kwentambo ye-polyurethane.
Iimpawu eziphambili ezi-8：
1. Ukumelana nokunxiba
Xa intambo idla ngokusetyenziswa ngendlela yoomatshini efana nokukhuhlana, ukukrwela kunye nokusila ngexesha lokusetyenziswa, iya kubangela ukuba umphezulu wayo ubole kancinci kancinci, ngoko ke ukuguguleka kokukhethwa kwezinto kubaluleke kakhulu.
Izinto zeplastiki zeTPU zinokumelana nokuguguleka okuhle kakhulu kwaye zimelana nokuguguleka ngokuphindwe kahlanu kuneentambo zerabha zendalo ezineengubo. Ziyenye yezona zinto zikhethwayo kakhulu kwiimveliso ezimelana nokuguguleka.
2. Ukusebenza okuqinileyo
Amandla okutsalwa kweentambo ze-polyurethane afikelela kwi-38MPa, kwaye amandla okutsalwa kweentambo zerabha eziqhelekileyo (enye yezona ntambo zixhaphakileyo kwimarike) yi-8-12MPa kuphela.
Xa intambo isetyenziswa kwindawo apho itsalwa khona ngenkani, i-cable sheath enerabha ayinawo amandla okutsala, kwaye i-core iyaphuka lula emva kokuba ibekwe kuxinzelelo lwangaphandle. Ukumelana okuhle kokutsala kwe-polyurethane cable sheath kunye ne-insulation kudlala indima entle yokukhusela kwi-wire core, okwenza ihlale ixesha elide kwaye ihlale ixesha elide.
3. Ukusebenza kokukrazula
Amandla okukrazula kukukwazi kwezinto ukumelana nokukrazula. Ngokubanzi, i-TPU inokumelana nokukrazula okuphezulu, kwaye amandla okukrazula agqwesileyo kakhulu xa kuthelekiswa nerabha kunye neplastiki ezisetyenziswa rhoqo.
4. Ukusebenza ngokujikajika
Iintambo ezininzi zeplastiki (ezifana neRVV) zinokwaphuka lula phantsi koxinzelelo oluphindaphindwayo. Iintambo zepolyurethane zinokugcina ukumelana okuhle kokugoba phantsi kweemeko ezahlukeneyo, nto leyo eyenza zibe zezona zikhetho zilungileyo kwiindawo zokugoba eziphindaphindwayo.
5. Ukumelana ne-hydrolysis
Iintambo zePolyurethane zinokumelana kakuhle kwamanzi phantsi koxinzelelo, kwaye aziyi kuba ne-hydrolysis ecacileyo kwiminyaka eli-1 ukuya kwemi-2, ingakumbi uthotho lwe-polyether lungcono.
6. Ukumelana nobushushu obuphezulu kunye nokumelana ne-oxidation
Ngokubanzi, izinto zeplastiki ezikrwada zifakwa kwi-oxidized lula kwindawo engaphezulu kwama-70℃ ixesha elide, kwaye i-TPU inamandla amahle okulwa ne-antioxidant; ngokubanzi, ukumelana nobushushu be-TPU kunokufikelela kwi-120℃.
7. Ukumelana neoyile kunye neempawu zokuxhathisa amayeza
I-TPU yi-polymer ekwi-polar ephezulu kakhulu enokuthambekela okuncinci kakhulu kwiioyile zeminerali ezingezizo ze-polar kwaye ayidli ngokonakala kwiioyile zepetroli (ezifana ne-kerosene, ipetroli) kunye neeoyile zoomatshini (ezifana neoyile ye-hydraulic, ioyile yenjini, ioyile yokuthambisa, njl.njl.); phakathi kwazo, iimveliso zochungechunge lwe-polyester zingcono kwiintambo ze-polyurethane.
8. Ukusebenza kobushushu obuphantsi
Iintambo zepolyurethane zinokumelana okuhle kakhulu nobushushu obuphantsi kwaye zihlala zifikelela kwi -50℃. Zingatshintsha amasimi ahlukeneyo apho iintambo zePVC kunye nerabha zingasetyenziswa ngenxa yokuqhekeka kobushushu obuphantsi. Zifanelekile ngakumbi kwiintambo ezisetyenziswa kwiindawo ezibandayo kakhulu.
Iindawo zokusetyenziswa：
01Intambo yesicelo saselwandle
Iintlobo zeentambo zasemanzini zinokwahlulwa ngokulula kwiinkalo ezine.
Ngokwembono yolwakhiwo, yahlulwe kakhulu yaba ziintambo zenqanawa zasemanzini ezingundoqo ezintathu kunye neentambo zenqanawa zasemanzini ezingundoqo omnye. Imigca ephakathi nephantsi isebenzisa iintambo zenqanawa zasemanzini ezingundoqo ezintathu, kwaye imigca yenqwelo-moya ephezulu isebenzisa iintambo zenqanawa zasemanzini ezingundoqo omnye; ngokwembono yokusebenza, kwisiqingatha senkulungwane eyadlulayo, iintambo zasemanzini zazinomsebenzi olula wokudlulisa amandla. Ngoku iintambo zasemanzini zidibanisa imisebenzi emibini, zifezekisa ngempumelelo ukuhanjiswa kombane kunye nemiqondiso kumgca wentambo omnye; ngokwembono yokwakheka kwe-insulation, zahlulwe zaba ziintambo zasemanzini ezigqunywe ngeoyile kunye neentambo zasemanzini ezigqunywe ngeplastiki; ngokwembono yohlobo lomthwalo, zahlulwe zaba ziintambo zasemanzini ezingaphantsi kweDC kunye neentambo zasemanzini ezingaphantsi kwe-AC. Iimpawu zeentambo zasemanzini ezingaphantsi kwe-DC ziilahleko ezincinci kwaye kulula ukuzifezekisa ukuhanjiswa komgama omde, kodwa amava okusetyenziswa kweentambo zasemanzini ezingaphantsi kwe-DC akatyebanga. Iindleko zokwakha ezixhasayo zezikhululo zokuguqula i-DC ziphezulu, kwaye iintambo zasemanzini ezingaphantsi kwe-AC zinkulu, kodwa itekhnoloji yokusebenza nokugcinwa ivuthiwe kwaye iindleko zokwakha ezixhasayo zincinci. Ke ngoko, abayili beentambo zeentambo zasemanzini badla ngokunyanzeleka ukuba benze urhwebo lobuchwephesha nolwezoqoqosho ukuze bafumane iingenelo ezininzi.
02 Iirobhothi zoshishino kunye Intambo yeRobotics
Kuyaqondakala ukuba ngaphezulu kwesiqingatha seerobhothi ezintsha zoshishino kwihlabathi zifakiwe eTshayina, kwaye iirobhothi ezenziwe eTshayina nazo zinegalelo elikhulu. Njengezinto ezihambelana neerobhothi, imfuno yophuhliso lweentambo zerobhothi ayinakuthathelwa ingqalelo. Ishishini leerobhothi zoshishino liyanda eTshayina kwaye likwatsala umdla ongakumbi kwiinkampani zekhebula. Njengenxalenye ebalulekileyo yeerobhothi, Ucingo kunye neCable zibonakalise ukukhula okukhulu kwimfuno yemarike, kwaye iinkampani zentambo kunye neentambo ziya kuvula ithuba elinqabileyo lophuhliso kunye notshintsho.
03 Oomatshini bezibuko kunye nentambo yereyile ye-gantry crane
Intambo ye-gantry crane reel kufuneka ikwazi ukusonga intambo ngokuzenzekelayo, kwaye i-torque yokuqhuba ye-reel yentambo akufuneki ibe ngaphantsi kwe-torque ephezulu yokusonga efunekayo xa kusongwa intambo. Ngexesha lenkqubo yokukhulula intambo, amandla okutsala asebenza kumqhubi wentambo kufuneka abe mancinci kangangoko. Kwiintambo ezingenayo i-core eqinisiweyo, amandla aphezulu okutsala avumelekileyo asebenza kwicandelo elinqamlezileyo lomqhubi webhedu yi-20N/mm². Kwisantya sokujika kwentambo esifunekayo okanye ubunzima bentambo bunzima, intambo yentsimbi eqinisiweyo enokumelana namandla okutsala afunekayo kufuneka yongezwe njenge-core.
04Iintambo zoomatshini bobunjineli bemigodi
Iintambo kunye neentambo zoomatshini bobunjineli bemigodi zifuna ukumelana nokuguguleka okungcono, ukumelana ne-hydrolysis, ukumelana nobushushu obuphezulu kunye nokuxhathisa i-oxidation, ngoko ke iimfuno zezinto zentambo kunye neentambo nazo zingqongqo.
