Shenhai Explosion-Proof
Raws li kev sib piv kev ntsuas ntsuas (CTI), cov khoom siv rwb thaiv tsev siv hauv cov khoom siv hluav taws xob muaj kev ruaj ntseg zoo tuaj yeem muab faib ua peb theem: Kuv, II, thiab IIa, raws li qhia hauv Table 1.9. Raws li GB / T 4207-2012 “Cov txheej txheem rau kev txiav txim siab qhov ntsuas hluav taws xob taug qab ntawm cov khoom siv rwb thaiv tsev,” muaj kev muab qhab nia ntawm cov khoom siv rwb thaiv tsev uas nquag siv, raws li tau piav qhia hauv Table 1.10.
| Khoom qib | Piv rau Traceability Index (CTI) |
|---|---|
| Kuv | 600≤ CTI |
| II | 400≤ CTI 600 |
| IIIa ib | 175≤400 |
Tshaj qhov kev faib cov khoom siv no, cov ntaub ntawv rwb thaiv tsev yuav tsum ua tau raws li qhov yuav tsum tau ua haujlwm kub. Yog tias cov khoom siv hluav taws xob muaj kev nyab xeeb zoo dua qub ua haujlwm raws li kev tso cai txawv txav ntawm nws lub xeev ua haujlwm, nws qhov siab tshaj plaws ua haujlwm kub yuav tsum tsis txhob cuam tshuam rau nws cov khoom siv kho tshuab thiab hluav taws xob. Yog li ntawd, Qhov ntsuas kub ruaj khov ntawm cov khoom siv rwb thaiv tsev yuav tsum yog tsawg kawg 20 ° C siab dua li cov cuab yeej ua haujlwm siab tshaj plaws, thiab tsis qis dua 80 ° C.
| Khoom qib | Cov khoom siv rwb thaiv tsev |
|---|---|
| Kuv | Glazed ceramics, mica, iav |
| II | Melamine asbestos arc resistant yas, silicone organic pob zeb arc resistant yas, unsaturated polyester pab pawg khoom |
| IIIA | Polytetrafluoroethylene yas, melamine iav fiber ntau yas, epoxy iav ntaub board nrog nto kho nrog arc resistant xim |
Cov neeg tsim qauv tuaj yeem xaiv cov ntaub ntawv rwb thaiv tsev tsim nyog raws li kev ua haujlwm ntawm cov khoom siv hluav taws xob thiab lwm yam kev xav tau. Yog hais tias cov ntaub ntawv hais saum toj no tsis ua raws li qhov xav tau ntawm tus tsim, lwm cov ntaub ntawv tuaj yeem kuaj thiab muab qhab nia raws li tus qauv kev xeem (GB / T 4207-2012).
Nws yog ib qho tseem ceeb kom nco ntsoov tias “cov khoom siv rwb thaiv tsev” xa mus rau cov khoom uas muaj zog thaum ua haujlwm. Qee yam khoom siv, uas yog kua thaum lub sij hawm muab khoom thiab solidify thaum thov, kuj suav hais tias yog cov khoom siv rwb thaiv tsev, xws li insulating varnishes.
