ʻO Dipropylene Glycol Dimethyl Ether me CAS 111109-77-4
ʻO Dipropylene Glycol Dimethyl Ether i hoʻopōkole ʻia as DPGDME, me kahi cas no 111109-77-4, he mea hoʻoheheʻe aprotic polar i hoʻohana pinepine ʻia. Loaʻa i ka mea hoʻoheheʻe Dpdme ka polarity waena, hiki ke hoʻoheheʻe maʻalahi i ka wai, a hiki ke hui pū ʻia me ka hapa nui o nā mea hoʻoheheʻe organik. ʻO Dipropylene glycol dimethyl ether kahi mea hoʻoheheʻe kūpono "wai-organic phase" maikaʻi loa. ʻO ka mea hoʻoheheʻe Dpdme kahi mea hoʻoheheʻe waena-kikowaena, ʻaʻole hiki ke lapalapa akā pono e mālama ʻia mai nā lapalapa wela kiʻekiʻe.
He mea hoʻoheheʻe aloha kaiapuni ka Dipropylene glycol dimethyl ether me kahi ʻala palupalu ʻoluʻolu, ka wikiwiki o ka volatilization kūpono, ke kūpaʻa kemika maikaʻi loa, ka solubility maikaʻi loa a me ka palekana kiʻekiʻe i ke olakino kanaka. Ua helu ʻia ʻo ʻAmelika Hui Pū ʻIa a me ka ʻAhahui ʻEulopa he mau mea hoʻoheheʻe ʻōmaʻomaʻo no ka non HAP/NAP (non hazardous ma ka papa inoa o ka haumia ea). Hiki ke hoʻohana pinepine ʻia ka Dipropylene glycol dimethyl ether 99.0 i nā uhi wai a me nā uhi i hoʻōla ʻia.

Hoʻohana nui ʻia ka Dipropylene glycol dimethyl ether ma nā ʻano noiʻi ʻoihana a me ka ʻepekema like ʻole ma muli o kona mau ʻano o ka "haʻahaʻa haʻahaʻa, solubility kiʻekiʻe a me ka volatility haʻahaʻa":
ʻOihana uhi a me nā ʻīnika:Hoʻohana ʻia ka Dipropylene glycol dimethyl ether, ma ke ʻano he solvent a i ʻole co-solvent, i nā uhi wai, nā uhi solvent a me nā ʻīnika. Hiki iā ia ke hoʻomaikaʻi i ka solubility o nā resins (e like me nā resins acrylic a me nā resins polyurethane), hoʻonui i ka pae a me ka hoʻopili ʻana o nā uhi, a i ka manawa like e hōʻemi i ka hoʻokuʻu ʻana o nā hui organik volatile (VOCs).
Nā mea hoʻomaʻemaʻe a me nā mea hoʻohemo momona:Ma muli o ko lākou mau waiwai hydrophilic a me lipophilic, hiki ke hoʻohana ʻia i loko o nā ʻano "mea hoʻomaʻemaʻe wai" no nā ʻāpana uila a me nā mea hana pololei. Hiki iā lākou ke wehe pono i nā ʻōpala aila a me nā koena flux (nā koena flux), a ʻaʻole e hōʻino i nā mea kumu (e like me nā metala a me nā plastics).
Ma ke kahua o nā lāʻau lapaʻau a me nā pesticides:ʻO ka mea hoʻoheheʻe Dpdme, ma ke ʻano he "solvent/co-solvent" no nā mea hana o nā lāʻau lapaʻau a i ʻole nā pesticides, hoʻohana ʻia i ka hoʻomākaukau ʻana i nā wai waha a me nā pesticides concentrate emulsifiable. Hiki i ka Dipropylene glycol dimethyl ether ke hoʻonui i ka solubility a me ke kūpaʻa o nā mea hana me ka hoʻemi ʻana i ka huhū i ke kino kanaka a i ʻole nā mea kanu.
Ka hana kemika a me ka hopena waena:ʻO ka Dipropylene glycol dimethyl ether, ma ke ʻano he polar aprotic solvent, hiki ke pani i nā solvents kuʻuna ʻawahia loa a hoʻohana ʻia i nā hopena synthesis organik (e like me ka nucleophilic substitution a me nā catalytic reactions), hiki ke hoʻonui i ka helu o ka hopena a me ka hua huahana.
Mālama pilikino a me nā huahana kemika o kēlā me kēia lā:Hoʻohana ʻia ka Dipropylene glycol dimethyl ether i nā ʻāpana liʻiliʻi i nā huahana mālama ʻili a me nā mea hoʻonani (e like me nā kirīmi maka a me nā mea ʻala) ma ke ʻano he mea hoʻoheheʻe a moisturizer paha, e kōkua ana i ka hoʻoheheʻe ʻana i nā mea hana hiki ke hoʻoheheʻe ʻia i ka ʻaila (e like me ka huaora E), me ka hoʻomaikaʻi ʻana i ka ʻili a me ke kūpaʻa o nā huahana.
✅He maikaʻi ke ʻano o ka dipropylene glycol dimethyl ether Kina, hoʻohālikelike ʻia me ka hōʻailona Dow o ʻAmelika Hui Pū ʻIa
✅ Ka hana kiʻekiʻe a me ka lako paʻa
✅Hiki ke hoʻopilikino ʻia nā ʻōpala a me nā lepili e like me ka mea e pono ai
