Koj paub ntau npaum li cas txog cov polyurethane cables? (TPU cable)
Polyurethane Cables yog hais txog cov cables uas siv cov khoom siv polyurethane ua rwb thaiv tsev lossis lub plhaub. Lawv qhov kev tiv thaiv super hnav yog hais txog qhov kev tiv thaiv super hnav ntawm lub plhaub cable thiab txheej rwb thaiv tsev.
Cov khoom siv polyurethane siv rau hauv cov cables feem ntau hu ua TPU, uas yog thermoplastic polyurethane elastomer roj hmab. Nws feem ntau muab faib ua polyester hom thiab polyether hom, nrog rau qhov nyuaj (60HA-85HD), hnav-resistant, roj-resistant, pob tshab thiab elastic. TPU tsis yog tsuas yog muaj cov khoom zoo heev hnav-resistant, siab nro, siab nro, muaj zog thiab laus-resistant, tab sis kuj yog cov khoom siv zoo rau ib puag ncig.
Niaj hnub no, Lansheng Cable yuav coj koj mus rau 8 lub ntsiab lus tseem ceeb thiab thaj chaw siv ntawm polyurethane cable.
8 yam tseem ceeb：
1. Hnav tsis kam
Thaum lub cable feem ntau raug rau kev ua haujlwm xws li kev sib txhuam, khawb thiab sib tsoo thaum siv, nws yuav ua rau nws qhov chaw maj mam hnav, yog li qhov hnav tau ntawm kev xaiv cov khoom siv yog qhov tseem ceeb heev.
Cov khoom siv yas TPU muaj kev tiv taus zoo heev thiab tiv taus kev hnav ntau dua tsib zaug dua li cov roj hmab ntuj tsim. Lawv yog ib qho ntawm cov ntaub ntawv xaiv thawj zaug rau cov khoom siv tiv taus kev hnav.
2. Kev ua tau zoo ntawm lub zog
Lub zog tensile ntawm polyurethane cables yog txog li 38MPa, thiab lub zog tensile ntawm cov roj hmab tes tsho cables (ib qho ntawm cov cables feem ntau hauv khw) tsuas yog 8-12MPa.
Thaum siv cov xov hlau hauv ib puag ncig uas muaj kev sib txhuam, lub plhaub roj hmab tsis muaj zog tensile, thiab lub plawv yooj yim tawg tom qab raug kev ntxhov siab sab nraud. Lub plhaub polyurethane cable thiab rwb thaiv tsev zoo heev ua lub luag haujlwm tiv thaiv zoo rau lub plawv hlau, ua rau nws kav ntev thiab ruaj khov.
3. Kev ua tau zoo ntawm kua muag
Lub zog tsim kua muag yog lub peev xwm ntawm cov khoom siv los tiv taus kev tsim kua muag. Feem ntau hais lus, TPU muaj kev tiv taus kev tsim kua muag siab, thiab lub zog tsim kua muag zoo heev piv rau qee cov roj hmab thiab yas uas siv ntau.
4. Kev ua tau zoo
Ntau cov xov hlau yas (xws li RVV) feem ntau yuav tawg thaum muaj kev ntxhov siab ntau zaus. Cov xov hlau polyurethane tuaj yeem tiv taus kev khoov zoo heev hauv qab ntau qhov chaw sib txawv, ua rau lawv yog ib qho kev xaiv zoo tshaj plaws rau kev khoov ntau zaus.
5. Kev ua haujlwm hydrolysis
Cov xov hlau polyurethane muaj kev tiv thaiv dej zoo nyob rau hauv qhov turbidity, thiab yuav tsis muaj kev hydrolysis pom tseeb hauv 1 txog 2 xyoos, tshwj xeeb tshaj yog cov koob polyether zoo dua.
6. Kub siab ua haujlwm thiab oxidation tsis kam
Feem ntau, cov khoom siv yas yooj yim oxidized hauv ib puag ncig siab dua 70 ℃ rau lub sijhawm ntev, thiab TPU muaj peev xwm antioxidant zoo; feem ntau, TPU kub tsis kam tuaj yeem ncav cuag 120 ℃.
7. Kev tiv thaiv roj thiab tshuaj tiv thaiv cov khoom
TPU yog cov khoom siv polymer polar heev uas muaj kev sib raug zoo me ntsis nrog cov roj av uas tsis yog polar thiab yuav luag tsis muaj xeb hauv cov roj roj (xws li kerosene, roj av) thiab cov roj kho tshuab (xws li roj hydraulic, roj cav, roj lubricating, thiab lwm yam); ntawm lawv, cov khoom polyester series zoo dua hauv cov cables polyurethane.
8. Kev ua haujlwm kub tsawg
Cov xov hlau polyurethane muaj qhov tiv taus kub tsawg heev thiab feem ntau ncav cuag -50 ℃. Lawv tuaj yeem hloov ntau qhov chaw uas cov xov hlau PVC thiab roj hmab feem ntau tsis tuaj yeem siv vim qhov kub tsawg brittleness. Lawv tshwj xeeb tshaj yog rau cov xov hlau siv hauv thaj chaw txias heev.
Cov cheeb tsam thov：
01Cov ntaub ntawv thov dej hiav txwv
Cov hom cables hauv qab dej tuaj yeem faib ua plaub yam.
Los ntawm kev pom ntawm cov qauv, nws feem ntau muab faib ua peb-core submarine cables thiab ib-core submarine cables. Cov kab nruab nrab thiab qis-voltage siv peb-core submarine cables, thiab cov kab siab-voltage siv ib-core submarine cables; los ntawm kev pom ntawm kev ua haujlwm, ib nrab xyoo pua dhau los, submarine cables tsuas muaj lub luag haujlwm xa hluav taws xob yooj yim. Tam sim no submarine cables koom ua ke ob lub luag haujlwm, ua tiav kev xa hluav taws xob thiab cov cim ntawm tib kab cable; los ntawm kev pom ntawm kev sib xyaw ua ke, lawv tau muab faib ua roj-puv insulated submarine cables thiab extruded yas insulated submarine cables; los ntawm kev pom ntawm hom thauj khoom, lawv tau muab faib ua DC submarine cables thiab AC submarine cables. Cov yam ntxwv ntawm DC submarine cables yog qhov poob me me thiab yooj yim ua tiav kev xa mus ntev, tab sis kev paub txog kev siv DC submarine cables tsis nplua nuj. Cov nqi txhawb nqa kev tsim kho ntawm DC converter chaw nres tsheb siab, thiab AC submarine cables loj, tab sis kev siv tshuab ua haujlwm thiab txij nkawm yog laus thiab cov nqi txhawb nqa kev tsim kho yog me me. Yog li ntawd, cov neeg tsim qauv kab submarine cable feem ntau yuav tsum ua kev lag luam thiab kev lag luam pauv kom tau txiaj ntsig ntau tshaj plaws.
02 Cov neeg hlau ua lag luam thiab Cov Xov Tooj Hlau Robots
Nws nkag siab tias ntau tshaj ib nrab ntawm lub ntiaj teb cov neeg hlau tshiab hauv kev lag luam tau raug teeb tsa hauv Suav teb, thiab cov neeg hlau ua nyob rau hauv Suav teb kuj suav nrog feem ntau. Raws li cov khoom sib xws nrog cov neeg hlau, qhov kev thov rau kev tsim kho cable neeg hlau tsis tuaj yeem raug kwv yees tsis tau. Kev lag luam neeg hlau kev lag luam tab tom vam meej hauv Suav teb thiab kuj tau txais kev txaus siab ntau dua los ntawm cov tuam txhab cable. Raws li ib qho tseem ceeb ntawm cov neeg hlau, Hlau Thiab Cable tau pom tias muaj kev loj hlob sai heev hauv kev thov ua lag luam, thiab cov tuam txhab hlau thiab cable yuav coj mus rau hauv lub sijhawm tsis tshua muaj rau kev txhim kho thiab kev hloov pauv.
03 Chaw nres nkoj tshuab thiab gantry crane reel cable
Lub gantry crane reel cable yuav tsum muaj peev xwm qhwv lub cable tau, thiab lub zog tsav ntawm lub cable reel yuav tsum tsis pub tsawg dua qhov siab tshaj plaws qhwv lub zog xav tau thaum qhwv lub cable. Thaum lub sijhawm tso tawm cable, lub zog traction ua rau tus neeg hlau cable yuav tsum me li sai tau. Rau cov cables tsis muaj lub hauv paus ruaj khov, lub zog tension siab tshaj plaws uas tso cai ua rau ntawm qhov seem ntawm tus neeg hlau tooj liab yog 20N / mm². Rau qhov ceev winding cable xav tau lossis qhov hnyav cable hnyav, ib txoj hlua hlau reinforced uas tuaj yeem tiv taus lub zog traction xav tau yuav tsum tau ntxiv ua lub hauv paus.
04Cov cables rau kev siv tshuab hauv kev tsuas
Cov xov hlau thiab cov cables rau kev siv tshuab tsuas yog xav tau kev hnav zoo dua, kev ua kom tsis muaj zog, kev ua kom kub siab thiab kev ua kom tsis muaj zog, yog li cov kev cai rau cov ntaub ntawv hlau thiab cable kuj nruj heev.
