Hoʻohana
1.Commonly hoʻohana analytical reagents, hoʻohana nui no ka neutralization a acidification.ʻO nā mea hoʻoheheʻe wai wai ʻole, hoʻomākaukau ʻana i nā hāʻina buffer, synthesis organik.Ka hana ʻana i nā puaʻa, nā lāʻau lapaʻau, nā acetate fibers, acetyl compounds, etc. Hoʻohana ʻia ia e hoʻopau i ka phosphorus, sulfur, hydrohalic acid, a me nā mea ʻē aʻe. a me ka paʻakai, a hoʻohana i ka nui kūpono e like me nā pono hana.Hiki ke hoʻohana ʻia i mea hoʻonui ʻono no ka waiʻona koji, a ʻo ka nui i hoʻohana ʻia he 0.1-0.3g/kg.Hoʻohanaʻia e like me ka solvent i ka hanaʻana i ka rubber, plastics, dyes, a me nā mea'ē aʻe.
2. Hoʻohana maʻamau analytical reagents.Nā mea hoʻoheheʻe honua a me nā mea hoʻoheheʻe wai wai ʻole.Hoʻohana ʻia i ka hana ʻana i ka acetate, cellulose acetate, lāʻau lapaʻau, pigments, esters, plastics, mea ʻala, etc.
3.PH hooponopono waiwai.Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i ka ethyl acetate, ka hoʻomākaukau ʻana i nā fibers, nā pena, nā adhesives, copolymer resins, etc., ka hoʻomākaukau ʻana i ka acetic anhydride, chloroacetic acid, glycolic acid a me ka ʻoihana pickling.
4. Hiki ke hoʻohana ʻia no ka pickling ʻoihana.No ka hoʻomākaukau ʻana i nā fibers, coatings, adhesives, copolymer resins, etc.
5. He mea koʻikoʻi ka mea hoʻokalakupua kemika, hiki ke hana i nā ʻano mea like ʻole.Hoʻohana ʻia ka ʻoihana lāʻau lapaʻau e hoʻomākaukau i nā lāʻau lapaʻau like ʻole, hoʻohana ʻia ka ʻoihana dye e hana i nā ʻano mea like ʻole, a hoʻohana ʻia ka ʻoihana synthetic no ka synthesize i nā ʻano mea polymer, kahi mea koʻikoʻi koʻikoʻi koʻikoʻi.Eia kekahi, hoʻohana ʻia ʻo ia e like me nā mea hoʻoheheʻe ʻenehana, nā ʻili tanning agents, rubber latex coagulants, nā mea hoʻonaninani, nā mea ʻala ʻala, nā reagents kemika, etc.
6.Acetic acid hiki ke hoʻohana 'ia i loko o kekahi pickling a me ka polishing solutions, ma nawaliwali acidic solutions like buffers (e like me galvanizing, electroless nickel plating), i ka nickel plating electrolyte semi-bright like additives, in zinc, cadmium passivation solution hiki ke hoʻoikaika i ka adhesion. ʻO ke kiʻiʻoniʻoni passivation, a hoʻohana mau ʻia e hoʻoponopono i ka pH o ka waika palupalu plating solution, hiki ke hoʻohana ʻia ma ke ʻano he solvent no kekahi mau mea hoʻohui kūlohelohe (e like me ka coumarin).
7. Hoʻohana pinepine ʻia nā reagents analytical, nā mea hoʻoheheʻe maʻamau a me nā solvents titration non-aqueous, synthesis organik, synthesis o nā puaʻa a me nā lāʻau lapaʻau.
8.Hoʻohanaʻia i ka hanaʻana i ka acetate, cellulose acetate, lāʻau lapaʻau, pigments, esters, plastics, meaʻala, etc.
