Raws li peb paub, melamine thiab formaldehyde yog cov ntaub ntawv tseem ceeb rauMelamine Moulding Compound.
Kev poob qis ntawm kev lag luam tseem ceeb formaldehyde tus nqi yog pom tseeb hauv lub Plaub Hlis.
Thaum lub Plaub Hlis,kev lag luam tus nqi ntawm formaldehydefluctuated thiab txav mus.
1. Nyob rau hauv thawj ib nrab ntawm lub xyoo, qhov downstream thov kev ua tau zoo yog qhov nruab nrab, thiab qee qhov kev lag luam hauv cheeb tsam tsis muaj peev xwm, thiab qhov kev lag luam tag nrho yog qhov nruab nrab.
2. Nyob rau hauv nruab nrab ntawm lub xyoo, qhov kev thov sab kuj tseem tsis muaj zog, tab sis cov khoom muag muaj ntau, cov neeg muag khoom tau nquag xa khoom, thiab cov nqi tsom mus rau poob.
3. Nyob rau hauv nruab nrab ntawm lub hli, vim kev nce qib ntawm tus nqi sab, kev ua lag luam kev xav tau zoo tuaj, thiab tus nqi tsom tau ruaj khov thiab nce siab hauv lub sijhawm luv luv.Txawm li cas los xij, qhov kev thov sab nraud tsis tau zoo dua, thiab muaj qhov cuam tshuam tsis zoo ntawm cov nqi ntawm cov khoom siv raw khoom poob qis hauv ib nrab ntawm lub xyoo, thiab tus nqi nruab nrab ntawm formaldehyde kev ua lag luam tseem nyob qis qis.
Raws li ib qho khoom siv raw ntawm formaldehyde, methanol tuav txoj haujlwm tseem ceeb hauv cov nqi ntawm formaldehyde.Qhov sib txawv ntawm ob qhia tau hais tias muaj kev sib raug zoo siab, thiab tus nqi ntawm formaldehyde yog rhiab heev rau kev hloov pauv ntawm tus nqi ntawm cov khoom siv raw.
Nyob rau lub Plaub Hlis, kev lag luam methanol hauv tsev tau hloov pauv mus rau hauv qab, kev taw qhia tus nqi qis qis, kev ua lag luam tau poob qis txog qhov kev xav ntawm kev lag luam, thiab cov neeg muag khoom tau ua raws.Nrog rau qhov poob ntawm cov nqi formaldehyde, cov nyiaj tau los poob qis xyoo-rau-xyoo.
Huafu Chemicalcia siab tias kev lag luam formaldehyde hloov pauv tsis muaj zog nyob rau lub Tsib Hlis.Cov khoom lag luam muaj ntau, tab sis cov dej ntws qis tuaj yeem tswj cov kev xav tau nruj, thiab cov khoom siv thiab cov kev xav tau tseem yuav sib tw, thaum cov khoom siv raw khoom methanol yuav tsum hloov pauv tsis muaj zog, thiab cov nqi kuj tseem tsis muaj kev txhawb nqa.
Ntawm tag nrho, yog tias tsis muaj kev txhawb nqa zoo, nws xav tias kev ua lag luam formaldehyde yuav hloov pauv tsis muaj zog hauv lub Tsib Hlis.Kev xa mus rau cov kev cai ua haujlwm keeb kwm, kev ua lag luam yog nyob rau hauv lub caij nyoog off-season los ntawm Lub Rau Hli mus txog Lub Xya Hli, thiab tus nqi nruab nrab ntawm lub ntiajteb txawj nqus yuav hloov pauv thiab poob qis.
