ʻO ke kūlana paʻa o Dimethyl Formamide/DMF a me ke kumukūʻai hoʻokūkū
Noi
ʻO Dimethyl formamide (DMF) ma ke ʻano he mea maka kemika koʻikoʻi a me ka mea hoʻoheheʻe maikaʻi loa, i hoʻohana nui ʻia i ka polyurethane, acrylic, pharmaceuticals, pesticides, dyes, electronics a me nā ʻoihana ʻē aʻe. Holoi ʻia i ka ʻoihana polyurethane ma ke ʻano he mea hoʻōla, hoʻohana nui ʻia no ka hana ʻana i ka ʻili synthetic pulu; nā lāʻau lapaʻau synthetic i ka ʻoihana lāʻau lapaʻau e like me nā waena, hoʻohana nui ʻia i ka hoʻomākaukau ʻana o ka doxycycline, cortisone, sulfa drug production; ʻoihana acrylic ka papa kaapuni quenching ma ke ʻano he mea hoʻoheheʻe i hoʻohana nui ʻia no ka hana milo maloʻo acrylic; ʻoihana pesticide no ka synthesis o nā pesticides kiʻekiʻe a me ka haʻahaʻa haʻahaʻa; dyein i ka ʻoihana dye ma ke ʻano he mea hoʻoheheʻe; nā ʻāpana tinned i ka ʻoihana electronics e like me ka hoʻomaʻemaʻe, a pēlā aku; nā ʻoihana ʻē aʻe, me ka lawe ʻana i nā kinoea weliweli, crystallization pharmaceutical me ka hoʻohana ʻana i nā solvents.

Ka Waihona
ʻOiai ʻo Dimethyl Formamide (DMF) he kemika organik me nā waiwai lapalapa a me ka leaka, pono e hoʻomaopopo ʻia nā mea aʻe i ka wā e mālama ai:
1. Kahua mālama: Pono e mālama ʻia ka DMF i kahi anuanu, maloʻo a me ka ea maikaʻi, e pale i ka lā pololei a me ka mahana kiʻekiʻe. Pono e kaʻawale ka wahi mālama mai ke ahi, ka wela a me ka oxidant, nā hale pahū.
2. Pūʻolo: Pono e mālama ʻia ka DMFS i loko o nā pahu ea paʻa o ke ʻano paʻa, e like me nā ʻōmole aniani, nā ʻōmole palakiko a i ʻole nā pahu metala. Pono e nānā pinepine ʻia ka pono a me ka paʻa o nā pahu.
3. Kāohi i ka huikau: ʻAʻole pono e hui pū ʻia ka DMF me ka oxidant ikaika, ka waikawa ikaika, ke kumu ikaika a me nā mea ʻē aʻe e pale aku i nā hopena weliweli. I ke kaʻina hana o ka mālama ʻana, ka hoʻouka ʻana, ka wehe ʻana a me ka hoʻohana ʻana, pono e makaʻala e pale aku i ka hoʻokuʻi ʻana, ka friction a me ka haʻalulu, e pale aku i ka leakage a me nā ulia.
4. Kāohi i ka uila static: I ka mālama ʻana i ka DMF, ka hoʻouka ʻana, ka hoʻokuʻu ʻana a me ke kaʻina hana hoʻohana, pono e pale i ka hana ʻana o ka uila static. Pono e hana i nā hana kūpono, e like me ka hoʻoheheʻe ʻana, ka uhi ʻana, nā lako antistatic, a pēlā aku.
5. Ka ʻike ʻana i ka lepili: Pono e hōʻailona ʻia nā ipu DMF me nā lepili maopopo a me ka ʻike ʻana, e hōʻike ana i ka lā mālama, ka inoa, ka noʻonoʻo ʻana, ka nui a me nā ʻike ʻē aʻe, i mea e maʻalahi ai ka hoʻokele a me ka ʻike ʻana.
