Unoziva zvakawanda sei nezve tambo dze polyurethane? (tambo yeTPU)
Cable yePolyurethanes zvinoreva tambo dzinoshandisa zvinhu zvepolyurethane sechinodzivirira kana sheath. Kusapfeka kwavo kwakanyanya kunoreva kusapfeka kwakanyanya kwesheath yetambo uye sheath yekudzivirira.
Zvinhu zvinoshandiswa mu polyurethane muwaya zvinowanzonzi TPU, inova thermoplastic polyurethane elastomer rabha. Zvikurukuru yakakamurwa kuva polyester mhando ne polyether mhando, ine kuomarara (60HA-85HD), inodzivirira kupera, inodzivirira mafuta, inoonekera uye inonamira. TPU haina chete hunhu hwakanaka hunodzivirira kupera, kushushikana kwakanyanya, kushushikana kwakanyanya, hwakasimba uye hunodzivirira kukwegura, asiwo ipurasitiki yakakura ine hushamwari kune zvakatipoteredza.
Nhasi, Lansheng Cable ichakutungamirira kuburikidza nezvinhu zvisere zvikuru uye nzvimbo dzekushandisa tambo yepolyurethane.
Zvinhu zvikuru zvisere：
1. Kudzivirira kupfeka
Kana tambo yacho ichiwanzoitwa zvinhu zvakaita sekukweshana, kukwenya nekukuya panguva yekushandiswa, ichaita kuti pamusoro payo papere zvishoma nezvishoma, saka kupfekwa kwechinhu chacho kwakakosha zvikuru.
Zvinhu zvepurasitiki zveTPU zvinodzivirira kupfekwa zvakanaka uye zvinodzivirira kupfekwa zvakapetwa kashanu pane tambo dzechisikigo dzakaputirwa nerabha. Ndidzo dzimwe dzezvinhu zvinonyanya kusarudzwa pakugadzira zvinhu zvisingapfekwi.
2.Kushanda nesimba
Simba rekudhonza retambo dzepolyurethane rinosvika 38MPa, uye simba rekudhonza retambo dzerabha dzinoshandiswa (imwe yetambo dzinonyanya kushandiswa pamusika) i8-12MPa chete.
Kana tambo ikashandiswa munzvimbo ine kudhonzwa kwakasimba, sheath yetambo ine rabha haina simba rekudhonzwa zvakanaka, uye core inotyoka nyore nyore mushure mekumanikidzwa kwekunze. Kusasimba kwakanyanya kwe tensile sheath yetambo ye polyurethane uye insulation zvinoita basa rakanaka rekudzivirira core yetambo, zvichiita kuti igare kwenguva refu uye igare kwenguva refu.
3.Kuita kwekubvarura
Simba rekubvaruka ndiko kugona kwechigadzirwa ichi kuramba kubvaruka. Kazhinji, TPU inodzivirira kubvaruka zvakanyanya, uye simba rekubvaruka rakanaka kwazvo kana tichienzanisa nedzimwe rabha nepurasitiki zvinoshandiswa.
4.Kushandura mashandiro
Tambo zhinji dzepurasitiki (dzakadai seRVV) dzinogona kutyoka kana dzichimanikidzwa kakawanda. Tambo dzepolyurethane dzinogona kuramba dzichidzivirira kukotama zvakanaka munzvimbo dzakasiyana, zvichiita kuti dzive imwe yesarudzo dzakanakisisa dzenzvimbo dzinokotama kakawanda.
5. Kuramba kweHydrolysis
Tambo dzepolyurethane dzinodzivirira mvura zvakanaka kana dziine turbidity, uye hadzizosanganisirwe nemvura mukati megore rimwe kusvika maviri, kunyanya polyether series iri nani.
6.Kudzivirira kupisa kwakanyanya uye kupikiswa kwe oxidation
Kazhinji, zvinhu zvepurasitiki zvinogadziriswa nyore nyore munzvimbo inodarika 70℃ kwenguva yakareba, uye TPU ine kugona kwakanaka kwekuchengetedza maantioxidant; kazhinji, kuramba tembiricha yeTPU kunogona kusvika 120℃.
7. Kusagona mafuta uye kugona kuramba zvinodhaka
TPU ipurasitiki ine polar yakawanda ine polar shoma ine oiri dzezvicherwa dzisiri polar uye haikanganisi mumafuta emafuta (akadai separafini, peturu) uye mafuta emakanika (akadai semafuta ehydraulic, oiri yeinjini, oiri yekuzora, nezvimwewo); pakati pazvo, zvigadzirwa zvepolyester series zviri nani mutambo dzepolyurethane.
8.Kushanda kwekupisa kwakaderera
Tambo dzepolyurethane dzinodzivirira kupisa kwakaderera uye dzinowanzo svika -50℃. Dzinogona kutsiva minda yakasiyana-siyana uko tambo dzePVC nerabha dzisingakwanise kushandiswa nekuda kwekupisa kwakaderera. Dzakakodzera zvakanyanya tambo dzinoshandiswa munzvimbo dzinotonhora zvakanyanya.
Nzvimbo dzekushandisa：
01Tambo yekushandisa mugungwa
Mhando dzetambo dzemugungwa dzinogona kungopatsanurwa kubva muzvikamu zvina.
Kubva pamaonero echivakwa, inonyanya kukamurwa kuita tambo dzepasi pemvura dzine mativi matatu uye tambo dzepasi pemvura dzine mativi maviri. Mitsetse yepakati nepasi inoshandisa tambo dzepasi pemvura dzine mativi matatu, uye tambo dzepasi pemvura dzine mativi matatu dzinoshandisa tambo dzepasi pemvura dzine mativi maviri; kubva pamaonero ekushanda, makore makumi mashanu apfuura, tambo dzepasi pemvura dzaingova nebasa rekutumira simba riri nyore. Iye zvino tambo dzepasi pemvura dzinobatanidza mabasa maviri, zvichiita kuti magetsi nemasaini zvibudirire patambo imwe chete yetambo; kubva pamaonero ekugadzirwa kwe insulation, dzakakamurwa kuita tambo dzepasi pemvura dzine insulated dzakazadzwa nemafuta uye tambo dzepasi pemvura dzakaburitswa nepurasitiki; kubva pamaonero emhando yemutoro, dzakakamurwa kuita tambo dzepasi pemvura dzeDC uye tambo dzepasi pemvura dzeAC. Hunhu hwetambo dzepasi pemvura dzeDC kurasikirwa kudiki uye kuri nyore kuwana kutumirwa kure, asi ruzivo rwekushandisa tambo dzepasi pemvura dzeDC haruna kupfuma. Mari yekutsigira kuvaka yeDC converter stations yakakwira, uye tambo dzepasi pemvura dzeAC dzakakura, asi tekinoroji yekushanda nekugadzirisa yakakura uye mari yekutsigira kuvaka idiki. Saka, vagadziri vetambo dzepasi pemvura vanowanzo fanira kuita kutengeserana kwehunyanzvi nehupfumi kuti vawane mabhenefiti akawanda.
02 marobhoti emaindasitiri uye Tambo yeRobotics
Zvinonzwisisika kuti anopfuura hafu yemarobhoti matsva epasi rose akaiswa muChina, uye marobhoti akagadzirwa muChina anewo chikamu chikuru. Sezvinhu zvinoenderana nemarobhoti, kudiwa kwekugadzirwa kwetambo dzemarobhoti hakugone kurerutswa. Indasitiri yemarobhoti eindasitiri iri kukura muChina uye iri kukwezvawo kufarira kwakawanda kubva kumakambani etambo. Sechikamu chakakosha chemarobhoti, Waya Netambo vakaratidza kukura kwakanyanya mukudiwa kwemusika, uye makambani emagetsi netambo achaunza mukana usingawanzoonekwi wekusimudzira nekushandura.
03 Michina yechiteshi uye tambo yecrane reel yegantry
Tambo ye gantry crane reel inofanira kukwanisa kuputira tambo yega, uye torque yekutyaira yetambo reel haifanirwe kunge iri pasi petorque yepamusoro yekuputira inodiwa pakuputira tambo. Munguva yekuburitsa tambo, simba rekubata rinoshanda patambo re cable rinofanira kunge riri diki sezvinobvira. Kune tambo dzisina musimboti wakasimbiswa, simba guru rekumanikidza rinobvumirwa rinoshanda pachikamu che copper conductor i20N/mm². Kune kumhanya kwetambo kunodiwa kana kuti huremu hwetambo hwacho hwakakura, tambo yesimbi yakasimbiswa inogona kutsungirira simba rekubata rinodiwa inofanira kuwedzerwa semusimboti.
04Tambo dzemichina yeinjiniya yemigodhi
Waya netambo dzemichina yeinjiniya yemigodhi dzinoda kuramba kusakara zviri nani, kuramba hydrolysis, kuramba kupisa kwakanyanya uye kuramba oxidation, saka zvinodiwa zvewaya netambo zvinhu zvakare zvakaoma.
