ʻO ke kūlana kiʻekiʻe 99% Polyethylene glycol dimethyl ether (NHD-250, NHD-500) cas 24991-55-7
Inoa Huahana: Polyethylene glycol dimethyl ether
Nā huaʻōlelo like: Poly(ethyleneglycol)dimethylether(NHD)
ʻAno: NHD-250, NHD-500
CAS: 24991-55-7
MF: (C2H4O)multC2H6O
ʻO Poly(ethyleneglycol)dimethylether(NHD) kahi ʻano hou o ka mea hoʻoheheʻe de-sulfurizing a me ka de-carbonate me ka maʻemaʻe kiʻekiʻe, kemika maikaʻi loa a me ke kūpaʻa wela i nā mea o ka acidity kiʻekiʻe, alkality a me ka mahana. He kūpono ia no ka hoʻomaʻemaʻe ʻana i ke kinoea anthraco-synthetic. Hiki iā ia ke hoʻohemo maikaʻi i ka hydrogen vulcanized mai ka hui ʻana o ke kinoea waikawa o ke kinoea kūlohelohe, ke kinoea kahua aila, ke kinoea lanahu i nā hale hana a i ʻole nā kūlanakauhale a me ke kinoea petroleum liquefied. Ma ke ʻano kūikawā, hiki iā ia ke hoʻohemo maikaʻi i ka sulfur organik.
Ma ke ʻano he mea wehe i nā kinoea waikawa (e like me H2S, C02, cos, etc.), plasticizer, binder compound, antistatic agent, textile printing and dyeing agent ma ke ʻano he mea kōkua, ʻoihana paʻi ma ke ʻano he hoʻomākaukau ʻana i ka ʻīnika kūikawā a me ka mea hoʻomohala, nā mea paʻi a me nā mea hoʻomaʻemaʻe lako paʻi, hoʻomaʻemaʻe ʻoihana (hana nui i ka detergent halogen-free), detergent i kēlā me kēia lā, organic reaction solvent a i ʻole phase transfer catalyst, pena solvent, pena remover a defoamer, etc.
