Pahū ʻo Shenhai
E hoʻomaka kākou ma ka wehewehe ʻana i nā ʻano loiloi pahū, ka mea a lakou i hoike mai ai, a pehea e koho ai ia lakou ma ka hana, me ka hoʻohana ʻana i nā pahu hāʻawi pahū-hōʻoia ma ke ʻano he laʻana.
| Hui kinoea/hui wela | T1 | T2 | T3 | T4 | T5 | T6 |
|---|---|---|---|---|---|---|
| IIA | Formaldehyde, toluene, methyl ester, acetylene, propane, acetone, ʻakika ʻakika, benzene, styrene, kalapona kalapona, ethyl acetate, ʻakika acetic, chlorobenzene, methyl acetate, chlorine | Methanol, ethanol, ethylbenzene, propanol, propylene, butanol, butyl acetate, amyl acetate, cyclopentane | Pentane, pentanol, hexane, ethanol, heptana, octane, cyclohexanol, turpentine, naphtha, ʻaila ʻaila (me ka hinuhinu), aila wahie, pentanol tetrachloride | Acetaldehyde, trimethylamine | Ethyl nitrite | |
| IIB | Propylene ester, dimethyl etera | Butadiene, epoxy propane, ethylene | ʻO ka dimethyl ether, acrolein, hydrogen carbide | |||
| IIC | Hūhāhā, kinoea wai | Acetylene | Kalapona disulfide | Ethyl nitrate |
Ka hōʻailona hōʻoia:
ʻO Ex d IIB T4 Gb/Ex tD A21 IP65 T130 °C he palapala hōʻoia honua no ka pale kinoea a me ka pahū lepo., kahi o ka ʻāpana ma mua o ka ʻoki (/) hōʻike i ka pae pahū kinoea, a ʻo ka ʻāpana ma hope o ka slash e hōʻike ana i ka pahū lepo.
Ex: Hoailona pahū, ka hōʻano maʻamau o IEC (Komisina Electrotechnical International) pahū-pale helu.
d: Pahu ahi ʻano ʻano, e hōʻike ana i ke ʻano mua o ka pale pahū he pale ahi.
IIB: Hōʻike i ka palekana pahū kinoea Papa B.
T4: Hōʻike i ka mahana wela papa.
ʻO Gb: Hōʻike i kēia huahana kūpono no Zone 1 pale pahū.
No ka pahū lepo hapa i ka hapa hope, lawa ia e hoʻokō i ka pae kiʻekiʻe o ka pale lepo 6 ma muli o nā kūlana pahū kinoea.
tD: Hōʻike i ke ʻano o ka pale pa (ka pale ʻana i ka ʻā ʻana o ka lepo me ka pā).
A21: Hōʻike i ka wahi kūpono, kūpono no Zone 21, ʻĀpana 22.
IP65: Hōʻike i ka pae palekana.
He mea koʻikoʻi ke koho i ka helu pahū-hōʻoia kūpono i nā kaiapuni maoli.
Ka mua, he mea nui e hoʻomaopopo i ʻelua ʻāpana nui, e like me ka mea i wehewehe ʻia ma lalo nei:
ʻAno pahū:
Papa I: Nā lako uila no nā lua lanahu ma lalo o ka honua;
Papa II: Nā lako uila no nā mea ʻē aʻe pahū kaiaea kino koe na mine lanahu a ma lalo o ka honua.
Hiki ke maheleia ka papa II i IIA, IIB, a me IIC, kahi hiki ke hoʻohana ʻia nā mea hana i kaha ʻia i ka IIB ma lalo o nā kūlana kūpono no nā mea IIA; Hiki ke hoʻohana ʻia ka IIC ma lalo o nā kūlana kūpono no ka IIA a me IIB.
Papa III: ʻO nā lako uila no nā wahi lepo pahū ma waho aʻe o nā mine lanahu.
IIIA: Nā lele lele; IIIB: lepo hoʻokele ʻole; IIIC: lepo hoʻokele.
Nā wahi pahū:
ʻĀpana 0: Kahi e loaʻa mau ai nā kinoea pahū; pilikia mau no ka oi aku 1000 hola/makahiki;
ʻĀpana 1: Mahea hikiwawe Hiki ke kinoea i ka wā o ka hana maʻamau; pōʻino loa no 10 i 1000 hola/makahiki;
ʻĀpana 2: ʻAʻole loaʻa nā kinoea lapalapa a, inā hiki mai, ʻaʻole pinepine a pōkole paha; hazardously hiki mai no 0.1 i 10 hola/makahiki.
He mea nui e hoʻomaopopo e pili ana mākou i ka Papa II a me III, ʻĀpana 1, ʻĀpana 2; ʻĀpana 21, ʻĀpana 22.
ʻO ka maʻamau, hiki i ka IIB ua lawa no ke kinoea, aka, no ka hydrogen, acetylene, a me carbon disulfide, koi ʻia kahi kiʻekiʻe o ka IIC. No ka pale pahū lepo, e hoʻokō wale i ke kinoea kūpono pae pahū a me ka papa lepo kiekie loa.
Aia kekahi ʻano hui pū pahu hāʻina pahū helu helu: ExdeIIBT4Gb.
