ʻO ka Papa Hoʻopaʻa Pahū-Hanakini Papa CT1 a i ʻole CT4

ʻO ka maʻamau, ʻO ka helu ʻana i ka pahū-hōʻoia no nā ʻāpana hydrogen ʻo ka IIC grade. No nā lako i helu ʻia ʻo T1, ʻo ka wela o ka ʻili kiʻekiʻe ma lalo o 450°C. Hāʻawi ʻia i ka mahana wela o ka hydrogen i 574 ° C, ʻO ke koho ʻana iā T1 ua lawa.

ʻO ka pae haʻahaʻa loa ma mahana wela hoʻokaʻawale, ua kūpono kekahi T-rating i nā pae hoʻohālike. No laila, i loko hydrogen pahū-pale helu, ʻO CT1 a me CT4 nā koho kūpono, me nā mea hana CT1 ʻoi aku ka maikaʻi o ke kumu kūʻai.
