Dab tsi yog lub npe ntawm cov apparatus siv hauv Flash thiab hluav taws?

Thawj cov cuab yeej siv siv los ntsuasFlash pointthiabHluav Taws Pointntawm cov kua dej (tshwj xeeb tshaj yog cov khoom siv roj av, roj nplua nyeem, thiab tshuaj lom neeg) hu ua aCleveland qhib khob tester (Coct).

Ntawm no yog qhov tawg:

Flash Toint:Tsawg tshaj plaws kub tshaj plaws ntawm qhov twg ib qho kua muab tawm txaus vapor los tsim ib qho kev sib raug zoo nrog cuaze rau nws saum npoo, tsim cov teeb meem luv luv thaum qhov chaw tiv thaiv yog thov .

Hluav Taws Point:Qhov kub uas cov vapor tsim los ntawm cov kua yuav txhawb nqa kev sib txuas ntawm {} Nws yog ob peb qib siab dua flash poin .

Vim li cas lub cleveland qhib khob?

Qhib Lub khob tsim:Cov qauv raug sim nyob rau hauv lub khob qhib nthuav tawm rau cov huab cua . cov khoom siv uas vapors uas muaj peev xwm sib xyaw nrog cua .

Cov Qauv Xeem:Nws ua raws cov qauv thoob ntiaj teb (zoo liASTM D92thiabISO 2592) Rau kev txiav txim siab nyem thiab hluav taws kub cov ntsiab lus ntawm cov kua nrog nrog flash cov ntsiab lus saum 79℃f) thiab qis dua 400℃(752℃f) .

Nws ua haujlwm li cas:Cov kua ua kua yog rhuab hauv lub khob ntawm tus tswj cov nplaim hluav taws xob (lossis qhov ntsuas kub ntawm cov nplaim hluav taws xob)

Lwm yam apparatus (rau cov ntsiab lus):

Pensky-Martens Kaw Khob tester (PMCC):Siv rau kev ntsuas covFlash pointcov kua dej (tshwj xeeb yog cov roj, cov kuab tshuaj) nrog Flash cov ntsiab lus hauv qab 70℃(158 degree) tej zaum yuav ploj hauv lub khob qhib. nws yog akaw lawmsystem (Astm D93, ISO 2719) . Thaum nws muaj kev ntsuas hluav taws muaj peev xwm tshwm sim hauv qhov kev hloov pauv no, txawm tias nws tsis tshua muaj.

Tag obliabue (tag) Kaw khob tester:Zoo ib yam li cov pensky-martens tab sis tsim rau cov khoom qis dua nyem cov ntaub ntawv (ASTM D56).

Hauv cov ntsiab lus:

Rau kev ntsuasOb lub eeb taw tes thiab hluav taws taw tesntawm ntau dua flash point kua (zoo li cov roj lubricating, bitumen, xim av) nyob rau hauv qhib kev mob, tusCleveland qhib khob tester (Coct)Puas yog tus qauv txheem zoo .

Rau kev ntsuas tusFlash pointntawm ntau cov kua dej siab (zoo li roj av, cov kuab tshuaj, kerosene) nyob rau hauv cov xwm txheej kaw, tusPensky-Martens Kaw Khob tester (PMCC)yog txheem .
