Kub kub silicone roj hmab cables yog dav siv nyob rau hauv siab - kub thiab hnyav ib puag ncig xws li metallurgy, fais fab, thiab tshuaj engineering vim lawv zoo heev kub tsis kam, txias tsis kam, yooj, thiab hluav taws xob rwb thaiv tsev zog. Txhawm rau kom ntseeg tau tias nws lub sijhawm ua haujlwm ntev - muaj kev nyab xeeb thiab txhim khu kev qha, cov txheej txheem ntawm cov ntsuas kev ua haujlwm tseem ceeb yuav tsum raug kuaj thiab raug lees paub. Tag nrho cov kev ntsuam xyuas feem ntau yog muab faib ua plaub qhov loj: kev ua haujlwm hluav taws xob, kev ua haujlwm thermal, kev ua haujlwm zoo, thiab kev ua haujlwm ib puag ncig.
1. Kev ntsuas hluav taws xob ua haujlwm
Qhov no yog qhov tseem ceeb tshaj plaws thiab tseem ceeb ntawm cov khoom siv rau cov cables, feem ntau los xyuas kom meej lawv cov rwb thaiv tsev kev ntseeg siab ntawm qhov ntsuas kub.
- Fais fab zaus withstand voltage test:Ntawm chav tsev kub thiab kub siab (xws li 200 degree), siv lub zog zaus AC voltage ob peb zaug ntawm qhov ntsuas hluav taws xob rau cov tub ntxhais insulated ntawm lub cable thiab tuav nws rau qee lub sijhawm los xyuas seb puas muaj cov txheej txheem rwb thaiv tsev puas lawm. Qhov no yog qhov kev xeem tseem ceeb los xyuas kom meej lub zog rwb thaiv tsev.
- Kev ntsuas hluav taws xob rwb thaiv tsev:ntsuas qhov tsis kam ntawm tus neeg xyuas pib thiab cov txheej txheem rwb thaiv tsev, ntsuas qhov ntim electronegativity ntawm cov khoom siv rwb thaiv tsev, thiab kev ua haujlwm siab yog qhov yooj yim lav rau kev rwb thaiv tsev zoo.
- Kev kuaj qhov tso tawm ib nrab:kuaj pom muaj qhov tshwm sim me me ntawm qhov paug tawm sab hauv lossis ntawm qhov chaw ntawm rwb thaiv tsev, uas yog qhov taw qhia rhiab rau kev ntsuas qhov tsis xws luag sab hauv thiab ntev - lub sij hawm aging tiam sis ntawm rwb thaiv tsev.
2. Kev ntsuas kub ua haujlwm
Qhov kev ntsuas no ncaj qha txheeb xyuas qhov muaj peev xwm tiag tiag hauv qab "siab kub" daim ntawv lo.
- Lub sij hawm ntev siab -kub kev laus kuaj:Muab cov qauv coj mus tso rau hauv qhov cub kub tsis tu ncua (xws li 200℃lossis siab dua), ua kom sov ntxiv rau ob peb teev qhuav, thiab tsis tu ncua ntsuas tus nqi ntawm kev hloov pauv hauv nws cov khoom siv kho tshuab (xws li lub zog tensile thiab elongation thaum so). Ntsuas qhov ntev - lub sij hawm thermal stability thiab kev pab lub neej ntawm cov khoom los ntawm kev sib piv cov ntaub ntawv ua ntej thiab tom qab aging.
- Thermal Extension Test:ntsuas qhov elongation thiab deformation ntawm rwb thaiv tsev los yog sheath cov ntaub ntawv nyob rau hauv qhov ntsuas kub thiab load, los soj ntsuam cov℃ntawm crosslinking (vulcanization) thiab deformation kuj ntawm silicone roj hmab.
- Heat shock resistance test:Cov qauv cable yog raug rau ntau lub voj voog ntawm qhov kub thiab txias (xws li 200 degree) thiab qis kub (xws li -50 degree) los xyuas qhov tawg thiab deformation ntawm rwb thaiv tsev thiab sheath, thiab ntsuas nws kam rau siab rau qhov kub thiab txias hloov tam sim ntawd.
3. Kev ntsuas kev ua tau zoo ntawm cov tshuab
Ntsuam xyuas lub peev xwm ntawm cov cables kom tiv thaiv kev ntxhov siab thaum siv thiab siv.
- Tensile lub zog thiab elongation ntawm kev xeem tawg:Ntsuas qhov siab tshaj plaws tensile lub zog thiab elongation ntev ntawm rwb thaiv tsev thiab sheath ntaub ntawv ua ntej lawv tawg, xav txog lub toughness thiab lub zog ntawm cov khoom. Tear lub zog kuaj: Rau silicone roj hmab sheaths, sim lawv lub peev xwm los tiv thaiv tawg expansion, uas yog ib qho tseem ceeb rau kev tiv thaiv installation puas.
- Bending xeem:Lub cable yog rov khoov duav ib ncig ntawm ib lub tog raj kheej ntawm ib txoj kab uas hla ntawm qhov kub thiab txias (xws li -30 degree) los xyuas qhov rwb thaiv tsev tawg thiab xyuas nws qhov kub thiab txias yooj yim.
4. Environmental resistance test
Simulate cov teeb meem tshuaj lom neeg thiab lub cev uas yuav ntsib hauv qhov chaw siv tiag tiag.
- Nplaim retardancy test:Kev ntsuam xyuas lub peev xwm ntawm ib lub cable los tiv thaiv cov nplaim hluav taws los ntawm kev kub nyhiab los yog bundled cable burning tests yog qhov taw qhia tseem ceeb ntawm kev nyab xeeb.
- Kev ntsuam xyuas roj thiab tshuaj lom neeg:Soak cov qauv hauv cov roj tshwj xeeb lossis tshuaj hnyav rau ib lub sijhawm, sim nws qhov hnyav, ntim hloov pauv, thiab cov cuab yeej cuab tam tuav tus nqi, thiab ntsuas nws txoj kev kam rau siab hauv ib puag ncig nyuaj xws li chemical engineering.
- Ozone resistance thiab ultraviolet resistance test:rau qhov chaw qhuav sab nraum zoov lossis qhov ntswg qhov ntswg, sim qhov kev hloov pauv ntawm cov ntaub ntawv tom qab cov pa oxygen lossis ultraviolet hluav taws xob, thiab ntsuas lawv cov peev xwm tiv thaiv - laus.
