Huahana Huahana
- ʻO PEG ka pōkole o ka inoa Pelekane polyethylene glycol. ʻO ka PEG 200 ʻaʻohe mea ʻawaʻawa, ʻaʻole hoʻonāukiuki, maikaʻi ka hoʻoheheʻe wai, a maikaʻi hoʻi ka hoʻohālikelike ʻana me nā ʻāpana organik he nui. Loaʻa iā lākou ka lubricity maikaʻi loa, ka paʻa ʻana o ka wai, ka dispersibility, adhesives, antistatic agents a softeners, etc., a hoʻohana ʻia i ka cosmetics, pharmaceuticals, chemical fibers, rubber, plastics, paper, paint, electroplating, pesticides, metal processing and food processing, etc. .
- Hiki ke hoʻohana ʻia ʻo PEG-200 ma ke ʻano he kumu no ka synthesis organik a me kahi mea lawe wela me nā koi kiʻekiʻe. Hiki ke hoʻohana ʻia e like me ka humectant, inorganic paʻakai solubilizer, a me ka viscosity regulator i ka ʻoihana kemika i kēlā me kēia lā; hiki ke hoʻohana ʻia ma ke ʻano he mea palupalu a antistatic i ka ʻoihana textile. ; Hoʻohana ʻia ma ke ʻano he mea hoʻomaʻemaʻe i ka hana pepa a me nā ʻoihana pesticide. Ma ke ʻano he mea hoʻoheheʻe hoʻoheheʻe metala, kaha kiʻi metala, hehi a hana ʻana paha i ka lubricant a me ka ʻoki ʻana i ka wai, ka wili ʻana i ka mea hoʻomaʻamaʻa lubricating polishing agent, welding agent, etc.; hoʻohana ʻia ma ke ʻano he lubricant i ka ʻoihana pepa, a me nā mea ʻē aʻe, a hoʻohana pū ʻia e like me ka mea hoʻoheheʻe wela e hoʻonui ai i ka hiki ke hoʻomaʻemaʻe wikiwiki. ʻO PEG-200 he mea ʻawaʻawa ʻole, ʻaʻole hiki ke puhi ʻia, a mālama ʻia a lawe ʻia e like me nā kemika maʻamau. E mālama i kahi maloʻo a me ka makani.
