1. Atụmatụ Ngwaahịa:

Ọ bụ ihe siri ike nke na-acha ọcha ma na-esi isi nke formaldehyde. Ọ bụ ihe na-eme ka formaldehyde dị larịị nke na-enweghị ebe ọ na-agbaze.

2. Ojiji:

Polyformaldehyde nwere ike dochie mmiri ọgwụ formaldehyde nkịtị nke ụlọ ọrụ mmepụta ihe n'ime mmepụta nke ngwaahịa dị iche iche dị n'okpuru ala dịka ọgwụ nje, resin sịntetik, mkpuchi, na ọgwụ nje na-egbu nje.

E ji ya mee ihe dị ka ihe e ji emepụta kemịkalụ organic na resin sịntetik, nakwa ihe na-eme ka ọgwụ ghara ịdị irè, polyformaldehyde bụ formaldehyde siri ike nke nwere ọtụtụ formaldehyde, nke dị n'ụdị ihe siri ike ma dịkwa mfe ịchekwa na ibugharị.

① Ọgwụ nje: ọgwụ ogwu ndị e ji aka mee dịka acetochlor, butachlor, na glyphosate;

② Agba: agba ụgbọ ala dị elu nke e ji aka mee;

③ Resin: resin urea formaldehyde sịntetik, resin phenolic, resin polyacetal, resin melamine, resin mgbanwe ion, na ihe nrapado dị iche iche;

④ Ime akwụkwọ: ihe eji eme ka akwụkwọ sịntetik sie ike;

⑤ Ntugharị: ihe na-ewepụ ájá, ihe na-eme ka ihe na-egbuke egbuke;

⑥ Ọrụ ugbo anụmanụ: ọgwụ nje na-egbu egbu.

⑦ Ihe ndị e ji emepụta ihe ndị sitere n'okike: eji kwadebe pentaerythritol, trimethylolpropane, glycerol, acrylic acid, methyl acrylate, methacrylic acid, N-hydroxymethylacrylamide, alkylphenol, methyl vinyl ketone, wdg.

⑧ Ndị ọzọ: Ọgwụ na ọgwụ nje. A na-eji ya dị ka ihe na-eme ka ahụ dị ọcha, ihe na-egbu nje, na ihe na-egbu nje. A na-eji ya eme ihe maka mmepụta ihe ndị sitere n'okike na ụlọ ọrụ ọgwụ.

3. Nchekwa:

Debe n'ụlọ nkwakọba ihe dị jụụ ma nwee ikuku. Zere ebe ọkụ na okpomọkụ na-esi apụta. Okpomọkụ nchekwa agaghị agafe 32 ℃, iru mmiri ekwesịghịkwa ịgafe 80%. A ga-echekwa ya iche na ihe ndị na-eme ka ihe dị n'ime ya dị ọcha, ihe ndị na-ebelata okpomọkụ, asịd, ntọala, wdg, ma zere ịgwakọta ebe nchekwa. Nabata ọkụ na ebe ikuku na-anaghị agbawa agbawa. Machibido iji ngwa igwe na ngwaọrụ ndị nwere ike ịkpata ọkụ. Ebe nchekwa kwesịrị inwe ihe ndị kwesịrị ekwesị iji nwee ihe ndị na-agbapụta mmiri.
