Hoohana Huahana
Hoʻohana ʻia ka ʻakika Fumaric i ka hana ʻana i nā resins polyester unsaturated. Hōʻike ʻia kēia ʻano resin e ke kūpaʻa kemika maikaʻi a me ka pale wela; ʻO ka copolymer o ka fumaric acid a me ka vinyl acetate he mea hoʻopili maikaʻi. ʻO Copolymer me styrene ka mea maka no ka hana ʻana i ka FRP. ʻO ka plasticizer i hana ʻia e ka fumaric acid he mea ʻawaʻawa ʻole a hiki ke hoʻohana ʻia no ka vinyl acetate latex e pili ana me ka meaʻai. He huahana kemika maikaʻi kēia e like me ka lāʻau lapaʻau a me ka mea hoʻomaʻemaʻe optical. Hoʻohana ʻia ia i ka hana ʻana o ka antidote dimercaptosuccinic acid i ka ʻoihana lāʻau. Hoʻopau ʻia ka waikawa fumaric me ka sodium carbonate no ka loaʻa ʻana o ka sodium fumarate ([17013-01-3]), a laila hoʻololi ʻia me ka ferrous sulfate e loaʻa ai ka fumarate hao, kahi i hoʻohana ʻia no ka mālama ʻana i ka anemia liʻiliʻi ʻulaʻula me nā lāʻau lapaʻau waiwai hao. Hoʻohana ʻia kēia huahana ma ke ʻano he meaʻai additive-sour agent, i hoʻohana ʻia i nā mea inu ʻoluʻolu, nā lole hua, jelly, ice cream, etc. ʻO ka paʻakai monosodium i hana ʻia e ka hopena o ka waikawa fumaric a me ka sodium hydroxide, ua hoʻohana ʻia ʻo ia ma ke ʻano he mea ʻawaʻawa a ma ke ʻano he waena no ka resin synthetic a me ka mordant.
1. Acid agent particles ma ke kaʻina hana hoʻopili, ʻaʻole maʻalahi e hoʻopunipuni, ka hoʻohana ʻole o ka lepo.
2. Kāohi i nā hopena kemika me nā mea maka a me nā mea kōkua
3. Hoʻopili i ka symmetry, hiki ke hoʻololi ʻia ka nui o nā ʻāpana e like me nā koi o ka mea kūʻai aku
4. Hoʻokuʻu lohi ka waikawa, hoʻonui i ka ʻono o ka huahana.
5. Ma ke ʻano he pauka uhi, hiki ke pale i ka hoʻopili ʻana o ka huahana, hoʻonui i ke ola o ka huahana.
Pūʻolo a me ka waiho ʻana
Pūʻolo:i hoʻopaʻa ʻia i loko o ka ʻeke i ulana ʻia i ka wai, 25kg no ka ʻeke a i ʻole e like me kāu mau koi.
Manaʻo: Hiki ke hoʻopaʻa ʻia ka haku melemele a me ka nui e nā koi o nā mea kūʻai aku
Waihona:
Hoʻopaʻa ʻia ma kahi ventilated, pale i ka ua, ka maʻa a me ka insolation. E ʻoluʻolu e lawelawe me ka mālama pono e pale i ka pōʻino o ka ʻeke, e mālama i nā mea ʻawaʻawa.

Hoʻomalu no ka mālama pono ʻana
NO ke ahi hamama. PALE ANA I KA PELE. Pūnaehana paʻa, nā lako uila a me nā kukui pahū lepo. ʻO ka lawelawe ʻana ma kahi wahi maikaʻi. E ʻaʻahu i nā lole pale kūpono. Hōʻalo i ka pili ʻana me ka ʻili a me nā maka. E pale i ka hana ʻana o ka lepo a me nā aerosol. E hoʻohana i nā mea hana ʻole. Kāohi i ke ahi i hana ʻia e ka mahu hoʻolele electrostatic.
