1. Nā Hiʻohiʻona Huahana:

He pauka keʻokeʻo paʻa me kahi ʻala lapalapa o ka formaldehyde. He polymer linear ia o ka formaldehyde me ka ʻole o kahi hoʻoheheʻe paʻa.

2. Nā hoʻohana:

Hiki i ka Polyformaldehyde ke pani i ka hopena wai formaldehyde ʻoihana maʻamau i ka synthesis o nā huahana like ʻole e like me nā pesticides, synthetic resins, coatings, a me nā disinfectants fumigation.

Hoʻohana ʻia ma ke ʻano he mea maka no nā kemika organik a me nā resins synthetic, a me kahi fumigant lāʻau lapaʻau, ʻo ka polyformaldehyde kahi formaldehyde paʻa me ka nui o ka formaldehyde, aia ma ke ʻano o nā ʻāpana paʻa a maʻalahi hoʻi e mālama a lawe.

① Nā Pesticides: nā herbicides synthetic e like me acetochlor, butachlor, a me glyphosate;

② Pena: pena kaʻa kiʻekiʻe synthetic;

③ Resin: synthetic urea formaldehyde resin, phenolic resin, polyacetal resin, melamine resin, ion exchange resin, a me nā mea hoʻopili like ʻole;

④ Hana pepa: mea hoʻoikaika pepa synthetic;

⑤ Ke hoʻolei ʻana: mea hoʻohemo one, mea hoʻopili hoʻoheheʻe synthetic;

⑥ Hana holoholona: mea hoʻomaʻemaʻe fumigation.

⑦ Nā mea maka organik: hoʻohana ʻia e hoʻomākaukau i ka pentaerythritol, trimethylolpropane, glycerol, acrylic acid, methyl acrylate, methacrylic acid, N-hydroxymethylacrylamide, alkylphenol, methyl vinyl ketone, etc.

⑧ ʻĒ aʻe: Lāʻau lapaʻau a me ka hoʻomaʻemaʻe ʻana. Hoʻohana ʻia ma ke ʻano he mea hoʻomaʻemaʻe, mea hoʻomaʻemaʻe, a me ka fumigant. Hoʻohana ʻia no ka synthesis organik a me ka ʻoihana lāʻau lapaʻau.

3. Ka mālama ʻana:

E mālama i loko o kahi hale kūʻai anuanu a me ka ea. E noho mamao aku mai nā kumu ahi a me ka wela. ʻAʻole e ʻoi aku ka mahana o ka mālama ʻana ma mua o 32 ℃, a ʻaʻole e ʻoi aku ka haʻahaʻa o ka ea ma mua o 80%. Pono e mālama ʻokoʻa ʻia mai nā mea hoʻomake, nā mea hoʻemi, nā waikawa, nā kumu, a me nā mea ʻē aʻe, a pale i ka hoʻohuihui ʻana i ka mālama ʻana. E hoʻohana i nā kukui pale pahū a me nā hale ea. E pāpā i ka hoʻohana ʻana i nā lako mīkini a me nā mea hana e maʻalahi ai ke hoʻoulu i nā huna ahi. Pono e hoʻolako ʻia kahi mālama me nā mea kūpono e hoʻopaʻa i nā mea i hoʻokahe ʻia.
