1. Cov yam ntxwv ntawm cov khoom:

Ib yam khoom dawb uas zoo li hmoov av uas muaj ntxhiab formaldehyde uas yooj yim hlawv. Nws yog ib hom polymer linear ntawm formaldehyde uas tsis muaj qhov melting point ruaj khov.

2. Siv:

Polyformaldehyde tuaj yeem hloov cov tshuaj formaldehyde aqueous hauv kev tsim cov khoom lag luam ntau yam xws li tshuaj tua kab, cov khoom siv hluavtaws, cov tshuaj pleev xim, thiab cov tshuaj tua kab mob fumigation.

Siv ua cov khoom siv raw rau cov tshuaj organic thiab cov resins hluavtaws, nrog rau cov tshuaj fumigant, polyformaldehyde yog cov khoom formaldehyde khov kho nrog cov ntsiab lus formaldehyde siab, uas yog nyob rau hauv daim ntawv ntawm cov khoom khov kho thiab yooj yim rau khaws cia thiab thauj.

① Tshuaj tua kab: cov tshuaj tua kab hluavtaws xws li acetochlor, butachlor, thiab glyphosate;

② Xim: xim pleev xim tsheb zoo tshaj plaws;

③ Cov tshuaj nplaum: cov tshuaj urea formaldehyde resin, phenolic resin, polyacetal resin, melamine resin, ion exchange resin, thiab ntau yam nplaum;

④ Kev ua ntawv: tus neeg sawv cev txhawb nqa ntawv hluavtaws;

⑤ Casting: xuab zeb stripping tus neeg sawv cev, hluavtaws casting nplaum;

⑥ Kev yug tsiaj: tshuaj tua kab mob fumigation.

⑦ Cov khoom siv raw organic: siv los npaj pentaerythritol, trimethylolpropane, glycerol, acrylic acid, methyl acrylate, methacrylic acid, N-hydroxymethylacrylamide, alkylphenol, methyl vinyl ketone, thiab lwm yam.

⑧ Lwm yam: Tshuaj thiab tshuaj tua kab mob. Siv ua tus neeg sawv cev tua kab mob, tshuaj tua kab mob, thiab tshuaj tua kab mob. Siv rau kev tsim cov organic thiab kev lag luam tshuaj.

3. Kev Khaws Cia:

Khaws cia rau hauv qhov chaw txias thiab muaj cua nkag. Nyob deb ntawm cov chaw uas muaj hluav taws thiab cua sov. Qhov kub thiab txias yuav tsum tsis pub tshaj 32 ℃, thiab qhov av noo yuav tsum tsis pub tshaj 80%. Yuav tsum khaws cia cais ntawm cov tshuaj oxidants, cov tshuaj txo qis, cov kua qaub, cov hauv paus, thiab lwm yam, thiab tsis txhob sib xyaw khaws cia. Siv cov teeb pom kev zoo thiab cov chaw ua pa uas tsis tawg. Txwv tsis pub siv cov khoom siv kho tshuab thiab cov cuab yeej uas yooj yim ua rau muaj hluav taws xob. Qhov chaw khaws cia yuav tsum muaj cov khoom siv tsim nyog los tswj cov khoom xau.
