Yuav sim cov nplaim hluav taws xob retardant kev ntaus nqi ntawm cov nplaim hluav taws xob-retardant silicone?
Kuaj cov nplaim hluavtaws-retardant ntsuam xyuas ntawm silicone yuav tsum ua raws cov qauv hauv tebchaws (GB), xws li UL, ISO), lossis kev cai kev lag luam.Hauv qab no yog cov qauv kev xeem thiab cov txheej txheem:
1. Cov nplaim hluav taws xob lub ntsej muag
(1) Kev ntsuam xyuas hluav taws kub (ur94)
Muaj feem xyuam rau: Kev ntsuam xyuas ntawm cov nplaim hluav-retardant kev ua yeeb yam ntawm cov yas, roj hmab, silicone, thiab lwm yam ntaub ntawv.
Txoj kev xeem:
Cov qauv silicone (feem ntau 125 hli × 13mm × tuab) yog tsau hauv txoj haujlwm ntsug.
Cov nplaim taws (methane lossis Butane) tau thov rau qhov qis kawg ntawm tus qauv rau 10 vib nas this, thiab kev coj tus cwj pwm hlawv.
Cov Kev Ntsuas Cov Kev Txiav Txim:
| Kev ntaus nqi | Kev hlawv lub sijhawm | Dripping cov dej paj rwg? |
|---|---|---|
| V-0 | Tsawg dua los yog sib npaug rau 10 sec | Tsis muaj |
| V-1 | Tsawg dua los yog sib npaug rau 30 sec | Tsis muaj |
| V-2 | Tsawg dua los yog sib npaug rau 30 sec | Tau |
| Ua tsis tau | >30 Sec | - |
(2) Cov pa oxygen investion (Loi) xeem (GB / T 2406 / ISO 4589)
Lub ntsiab lus: Kev txiav txim siab cov pa oxygen tsawg kawg hauv cov pa oxygen-nitrogen sib xyaw kom muaj kev sib xyaw ua ke.
Kev ua:
Tso cov qauv silicone hauv cov raj hluav taws xob pob tshab sib xyaw thiab ua kom paub sib txawv o₂ / n n mixed.
Ignite tus qauv thiab txiav txim siab cov oxygen qis tshaj plaws uas txhawb nqa kev sib txuas lus rau 3 feeb lossis hlawv ib ntev ntawm 50 hli.
Qho kawg:
Loi ntau dua los yog sib npaug rau 28%: Feem ntau suav cov nplaim hluavtaws-retardant (zoo ib yam li silicone muaj ntau tshaj 20% -24%).
(3) Kab rov tav hlav kab rov tav (GB / T 2408 / ISO 1210)
Muaj feem xyuam rau: Tshuaj ntsuam xyuas cov khoom hlawv ntawm cov ntaub ntawv nyob hauv kab rov tav.
Cov Kev Ntsuas Cov Kev Txiav Txim:
Kev kub loj dua los yog sib npaug rau 40mm / min (fh {1}}}}} -2 qib).
(4) Cov Hlau Hlau Ntsuas (IEC 60695-2-10)
Muaj feem xyuam rau: Ntsuas cov nplaim hluav taws retardancy ntawm silicone siv hauv cov khoom siv hluav taws xob thiab hluav taws xob.
Txoj kev xeem:
Ib qho 950 degree kub hlau yog siv rau cov qauv rau 30 feeb, thiab tej kev tiv thaiv lossis kev kub ntxhov.
2. Kuaj cov qib tseem ceeb
Qauv npaj:
Txiav cov qauv rau cov qauv qhov ntev (piv txwv li, sawb puab zoo li ul94, pas nrig rau loi).
Xyuas kom meej tias cov qauv yog pub dawb ntawm npuas thiab impurities, thiab ua tau raws li cov tuab uas yuav tsum tau (feem ntau {{mm mm).
Kev Kho Mob Ua Ntej:
Khaws cov qauv ntawm23 ± 2 Qibthiab50 ± 5% humidityrau 48 teev kom tsis txhob muaj kev cuam tshuam ib puag ncig.
Kuaj thaj chaw:
Ua kev sim hauv aCua-dawb, kub- - thiab cov av noo-tshuaj tswjTxhawm rau tiv thaiv kom tsis txhob muaj cua sab nraud los ntawm kev cuam tshuam cov nplaim taws.
Cov ntaub ntawv kaw cia:
Sau lub sijhawm hlawv, kev coj cwj pwm, nplaim taws kis ntev, thiab lwm yam.
3. Cov nplaim hluav taws-retardant silicone ntsuas
Silicone zoo tib yam: Feem ntau tsis-nplaim-retardant (Loi ~ 20% -24%).
Nplaim taws-retardant silicone:
Ul94 v -0: Cov nplaim hluav taws kub tshaj plaws qib rov qab (siv cov siv hauv kev lag luam hluav taws xob).
Ul94 hb: Hla tsuas yog txoj kab rov tav kev sim (cov nplaim hluav taws xob qis dua).
Loi ntau dua los yog sib npaug rau 30%: Cov nplaim hluav taws retardancy (piv txwv li, silicone nrog nplaim retardant additives).
4. Qhov xwm txheej cuam tshuam rau nplaim rov qab
Hom: Inorganic nplaim taws retardants xws liTxhuas hydroxidethiabMagnesium hydroxidetuaj yeem txhim kho cov nplaim hluavtaws rov qab.
Silicone Cov Khoom Siv: Phenyl siliconeyog ntau dua cov cua sov-tiv tausMethyl Silicone.
Qhov tuab: Cov qauv tuab tuab yog cov kev sim ua kom dhau qhov kev xeem (Piv txwv, ul94 muaj qis dua yuav tsum tau rau 3MM kuaj).
