Hōʻike kikoʻī
Diethyleneglycol diformate, i ʻike ʻia ʻo DEG diformate a i ʻole DMEG, he mea hoʻohui pū me ka formula (HOCH₂CH₂O)₂HCOO. He wai akaka, kala ʻole me ka ʻala ʻono iki.
ʻO kekahi mau waiwai nui a me nā hiʻohiʻona o ka diethyleneglycol diformate penei:
Hiki ke hoʻoheheʻe:Hiki ke hoʻoheheʻe ʻia ka DEG diformate i ka wai a me nā mea hoʻoheheʻe polar e like me ka ethanol a me ka acetone. He liʻiliʻi ka solubility i nā mea hoʻoheheʻe nonpolar.
Paʻa:Paʻa kēia hui ma lalo o nā kūlana maʻamau. ʻAʻole ia e decompose a hoʻohaʻahaʻa maʻalahi.
Lae paila:ʻO ka Diethyleneglycol diformate he wahi paila ma kahi o 245°C (473°F).
Palekana:Manaʻo ʻia ʻo DEG diformate he palekana ke hoʻohana ʻia a mālama pono ʻia. Eia nō naʻe, e like me nā mea kemika, pono e mālama ʻia me ka mālama pono, a pono e mālama ʻia i nā pale palekana kūpono.
He mea nui e hoʻomaopopo i ka hāʻawi ʻana o kēia hoʻolauna i kahi ʻike ākea o ka diethyleneglycol diformate a me kāna mau noi. No nā kikoʻī kikoʻī a me ka ʻike e pili ana i kona hoʻohana ʻana i kahi pōʻaiapili a ʻoihana paha, pono e nīnau i nā kumuwaiwai ʻenehana kūpono a i ʻole nā mea akamai.
Palapala noi
Loaʻa i ka Diethylene glycol diformate (DMEG) kekahi mau noi ma nā ʻoihana like ʻole. Eia kekahi o kāna mau hoʻohana maʻamau:
Mea hoʻoheheʻe:Hoʻohana pinepine ʻia ʻo DMEG ma ke ʻano he mea hoʻoheheʻe no nā ʻano mea like ʻole, me nā resins, nā uhi, a me nā kala. ʻO kona wahi paila kiʻekiʻe a me ka haʻahaʻa haʻahaʻa e kūpono ia no ka hoʻoheheʻe ʻana a me ka hoʻopuehu ʻana i nā mea like ʻole.
Kemimi waena:Hiki i ka DMEG ke hana ma ke ʻano he waena kemika i nā kaʻina hana synthesis. Hiki ke hoʻohana ʻia ma ke ʻano he mea maka no ka hana ʻana i nā kemika ʻē aʻe e like me nā esters, plasticizers, a me nā intermediates pharmaceutical.
Mea Hoʻomaʻemaʻe a Degreasing Agent:Hiki i ka DMEG ke wehe i ka aila, ka momona, a me nā mea haumia ʻē aʻe mai ka ʻili. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaʻemaʻe i nā ʻoihana ʻenehana e like me ka hoʻomaʻemaʻe metala, ka hoʻomaʻemaʻe ʻana i nā mea hana, a me ka hoʻomaʻemaʻe ʻana i nā mea uila.
ʻOihana Hoʻopili a me ka Sealant:Hiki ke hoʻohana ʻia ʻo DMEG ma ke ʻano he solvent a diluent i ka hana ʻana i nā mea hoʻopili a me nā mea hoʻopaʻa. Kōkua ia i ka hoʻokō ʻana i ka viscosity i makemake ʻia a hoʻomaikaʻi i ka noi a me nā ʻano maloʻo o ka huahana hope.
ʻOihana lole lole:Hoʻohana ʻia ʻo DMEG ma ke ʻano he mea hoʻoheheʻe i ke kaʻina hana kala a me ka paʻi ʻana o nā textiles. Kōkua ia i ka hoʻoheheʻe ʻana i nā kala a hoʻonui i ka wikiwiki o ka waihoʻoluʻu.
He mea nui e hoʻomaopopo he hiki ke ʻokoʻa ka noi kikoʻī o DMEG ma muli o ka ʻoihana a me ka hoʻohana i manaʻo ʻia. Pono nā mea hana a me nā mea hoʻohana o DMEG e nīnau mau i ka pepa ʻikepili palekana (SDS) a hahai i nā alakaʻi a me nā lula no ka mālama ʻana a me ka hoʻohana ʻana.
