Nyob rau xyoo tas los no, nrog rau kev loj hlob ntawm cov tsheb fais fab tshiab, qhov zaus ntawm kev sib tsoo hluav taws kub ntawm cov tsheb fais fab tshiab kuj tau nce ntxiv txhua xyoo, ua rau muaj kev phom sij rau kev nyab xeeb ntawm cov neeg tsav tsheb lub neej thiab khoom vaj khoom tsev. Cov ua rau muaj hluav taws kub hauv cov tsheb fais fab tshiab yog los ntawm ntau yam. Ntawm lawv, kev them ntau dhau, kev rho tawm, kev sib tsoo, kev taug kev hauv dej thiab lwm yam teeb meem ntawm lub roj teeb fais fab thiab cov txheej txheem tsim khoom yuav ua rau lub roj teeb kub hnyiab thiab ua rau lub tsheb fais fab tshiab kub hnyiab lossis tawg.
Yog tias muaj xwm txheej hluav taws kub hauv lub tsheb fais fab tshiab, txawm hais tias qhov kub ntawm lub roj teeb lithium-ion qis heev thaum nws hlawv, thaum lub roj teeb hluav taws kub tuag tag, qhov kub ntawm lub roj teeb tsis poob qis mus rau qib nyab xeeb sai sai, thiab muaj roj lom ntau heev. Txawm tias nws raug muab tso rau hauv dej, nws yuav siv sijhawm ntev kom nws qhov kub poob qis mus rau qib nyab xeeb, thiab lub roj teeb kuj yooj yim rov ua dua, uas kis tau sai heev.
Thaum lub tsheb fais fab tshiab kub hnyiab, qhov hluav taws xob thiab qhov kub ntawm lub roj teeb uas puas lawm yuav nce sai sai thiab lub sijhawm hloov pauv cua sov yuav luv heev, ua rau muaj thaj chaw loj ntawm qhov kub ntawm lub roj teeb hauv lub sijhawm luv luv. Yog tias qhov kev hloov pauv ntawm cov yam ntxwv ntawm lub roj teeb uas puas lawm tuaj yeem raug ntes tau raug thiab tus neeg tsav tsheb tuaj yeem raug ceeb toom, qhov tshwm sim ntawm kev sib tsoo yuav raug txo qis.
Thaum lub tsheb fais fab ntsib kev sib tsoo, lub roj teeb raug nias thiab sib tsoo, lossis lub tsheb fais fab kub hnyiab, lub plhaub roj teeb yog qhov tseem ceeb rau kev tiv thaiv lub roj teeb. Txhim kho kev ua haujlwm ntawm lub plhaub. Thaum lub roj teeb thermal runaway tshwm sim, lub plhaub hluav taws kub siab muaj lub luag haujlwm ntawm kev tiv thaiv kev sib kis ntawm hluav taws. Kev txhim kho kev ua haujlwm sealing ntawm lub roj teeb muaj qhov cuam tshuam loj rau kev tiv thaiv cov roj to thiab kev sib kis ntawm kev sib xyaw thaum lub roj teeb raug muab tso rau hauv dej lossis thermal runaway. Lub txheej hluav taws kub-retardant siv rau ntawm qhov chaw ntawm lub plhaub los txhim kho kev tiv thaiv hluav taws ntawm lub plhaub roj teeb.
nplaim-retardant melamine ua npuas ncauj can be installed between the module, battery cell and battery pack shell. Melamine foam may be assessed as one thermal or acoustic layer in a battery pack, but its ability to delay heat propagation or influence thermal-runaway behaviour must be established in the specific installed assembly. Foam alone cannot be relied on to stop cell-to-cell thermal runaway or fire spread. The structure of the battery box can also use high-strength materials, use reinforcing ribs or set up buffer devices, etc., and set up buffer structures to buffer and absorb part of the force of collisions, protect the battery pack from damage, and reduce the risk of short circuits caused by mechanical collisions.
At present, the fireproof materials of new energy vehicle battery packs are mainly laid with fireproof felt materials, such as insulation blankets, mica boards, ultra-fine glass wool, high silica cotton felts, etc. Although fireproof felt can effectively isolate heat diffusion, control the direction of fire, and delay the heat diffusion time of the battery, adding fireproof felt also has problems such as increased mass, which is not conducive to the development of lightweight vehicles, poor heat dissipation performance, and limitations in the design and construction process. Therefore, according to the market demand for safety and lightweight of power battery packs, melamine foam is one candidate for selected nonstructural thermal and acoustic functions in battery assemblies, subject to cell-level and system-level safety qualification.
SINOYQX muab cov ntaub ntawv tshaj lij thiab cov kev daws teeb meem rau kev tsim tsheb, tshwj xeeb tshaj yog rau cov txheej txheem siab ntawm cov roj teeb hluav taws xob tshiab rau Cov Hluav Taws Xob Hluav Taws Xob, Nplaim Retardant, thiab Kev Tiv Thaiv Thaum Tshav Kub Kub, raws li cov qauv tsim thiab kev tsim khoom, los ntawm kev tsim kho tshiab thiab kev tshawb fawb thiab kev loj hlob nrog nws YQX-C6 hom los ntawm kev kho mob tshwj xeeb melamine ua npuas ncauj.
SINOYQX Cov Khoom Siv Roj Teeb Tshiab Zog
- Flame behaviour: confirm UL94 and other applicable results using the specific material grade and test report; these do not establish battery-pack fire safety
- zoo heev thermal rwb thaiv tsev 0.035 W / (m * K)
- Electrical insulation: a dielectric rating must be demonstrated through applicable dielectric-strength, withstand-voltage, creepage and assembly-level tests; no voltage rating is implied by foam resistivity alone
- Service temperature: evaluate the exact foam grade, exposure duration and complete assembly; published material temperature limits are not an automatic battery-system rating
- Kev yooj ywm (qhov nyias tshaj plaws tuaj yeem ncav cuag 0.3 hli)
- Lub teeb (8 ~ 51KG / M3)
- Substance, emissions and acoustic performance: verify with grade-specific documentation. Combustion products must not be described as non-toxic; chemical resistance, antimicrobial properties and NRC depend on testing, grade and installed thickness
- Kev ua tiav theem ob (yooj yim txiav, tuaj yeem rov qab nplaum lossis laminated, thiab lwm yam)
