Hoʻohana
ʻO kekahi o nā hiʻohiʻona nui o ka dichloromethane ʻo kona versatility. Hoʻohana nui ʻia ʻo ia e like me ka solvent, extractant a me mutagen, e kaulana ai i nā laboratories a me nā keʻena noiʻi. ʻO kona hoʻoheheʻe ʻia i ka ethanol a me ka etera a me kona hiki ʻole i ke ahi ke lilo ia i mea palekana ʻoi aku ka palekana i nā mea hiki ke ahi e like me ka petroleum ether. Hoʻolilo kēia waiwai i ka dichloromethane i koho kaulana no ka fumigation palaoa a me ka refrigeration i loko o nā pahu hau haʻahaʻa haʻahaʻa a me nā lako ea. ʻO kona hiki ke hoʻololi i nā kemika pōʻino i ka mālama ʻana i ka hana kiʻekiʻe e lilo ia i koho mua i nā ʻoihana koʻikoʻi palekana.
Eia kekahi, he hana koʻikoʻi ka methylene chloride i ka ʻoihana uila. ʻO kāna mau mea hoʻomaʻemaʻe maikaʻi a me ka degreasing e kūpono ia no ka hoʻomaʻemaʻe maikaʻi i koi ʻia i ka hana uila. Mai nā papa kaapuni paʻakikī a hiki i nā ʻāpana liʻiliʻi, ʻo ka methylene chloride e hōʻoia i kahi kaʻina hana hoʻomaʻemaʻe ʻole. Eia kekahi, he mea koʻikoʻi loa ia i ka synthesis organik, hiki ke hana i ka nui o nā pūhui waiwai. ʻO kona noho ʻana ma nā ʻoihana like ʻole e hōʻike ana i kona versatility a indispensability.
Ma waho aʻe o ka hoʻohana nui ʻia ʻana, ʻoi aku ka maikaʻi o ka dichloromethane ma ke ʻano he anesthetic kūloko kūloko, mea kinai ahi, a me ka hoʻomaʻemaʻe pena ʻili metala a me ka mea hoʻohemo degreasing. ʻO kona hiki ke hāʻawi i ka anesthesia a me ka hoʻopau ʻana i ke ahi e hōʻike ana i kāna mau waiwai kūʻokoʻa. Eia kekahi, hoʻopau maikaʻi ia i nā pale i makemake ʻole ʻia a me nā mea haumia mai nā ʻili metala, e hōʻoia ana i kahi canvas maikaʻi loa no ka pena ʻana a me ka hana hou ʻana.
I ka hopena, ʻo ka dichloromethane kahi mea hoʻohui me nā waiwai maikaʻi loa. ʻO kona hiki ke hoʻololi i nā mea pōʻino me ka mālama ʻana i ka hana maikaʻi loa e lilo ia i waiwai waiwai ma nā ʻoihana lehulehu. Inā hoʻohana ʻia i ka fumigation palaoa, ka hana uila a i ʻole nā noi niho, ua hōʻike ʻia ka methylene chloride he koho hilinaʻi. Me kona laulā o nā noi a me nā waiwai kupaianaha, ua mākaukau kēia pūhui organik e hoʻololi i nā ʻoihana he nui a puni ka honua. E ʻike i ka mana o ka methylene chloride a wehe i nā mea hou i kāu hana.
