Hoʻohana

ʻAʻole hoʻohana wale ʻia kēia huahana no ka synthesis organik, akā hoʻohana nui ʻia e like me ke kiʻiʻoniʻoni cellulose acetate, cellulose triacetate spinning, petroleum dewaxing, aerosol a me nā lāʻau antibiotic, nā huaora, nā steroids i ka hana ʻana i nā mea hoʻoheheʻe, a me ka mea hoʻomaʻemaʻe hoʻomaʻemaʻe a me ka mea hoʻoneʻe. . Eia kekahi, hoʻohana ʻia ia no ka fumigation palaoa a me ka refrigeration o nā pahu hau haʻahaʻa haʻahaʻa a me nā ea. Hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻoheheʻe kōkua i ka hana ʻana i ka polyether urethane foams a ma ke ʻano he mea puhi no nā polysulfone foam extruded.

Palekana

liʻiliʻi loa ka ʻona, a ʻoi aku ka wikiwiki o ka ʻike ma hope o ka make ʻana, no laila hiki ke hoʻohana ʻia ma ke ʻano he anesthetic. Hoʻopilikia i ka ʻili a me ka mucous membrane. ʻIole ʻōpio makua waha waha ld501.6ml/kg. ʻO 500 × 10-6 ka palena kiʻekiʻe i ʻae ʻia. Pono ka hana e hoʻohana i ka mask gas, ʻike koke ʻia ma hope o ka make ʻana mai kahi hanana, ka mālama ʻana me ka pahu hao hao i pani ʻia, 250kg no ka pahu, kaʻa kaʻa kaʻa, hiki ke lawe ʻia ke kaʻa. Pono e mālama ʻia i loko o ke anuanu ʻeleʻele maloʻo, maikaʻi-ventilated wahi, e hoʻolohe i ka makū.
