1. Zinthu Zogulitsa:

Cholimba choyera ngati ufa chokhala ndi fungo loyaka la formaldehyde. Ndi polima yolunjika ya formaldehyde yopanda malo osungunuka okhazikika.

2. Ntchito:

Polyformaldehyde ikhoza kulowa m'malo mwa njira yamadzi ya formaldehyde ya mafakitale wamba popanga zinthu zosiyanasiyana monga mankhwala ophera tizilombo, ma resin opangidwa, zokutira, ndi mankhwala ophera tizilombo toyambitsa matenda.

Pogwiritsidwa ntchito ngati zinthu zopangira mankhwala achilengedwe ndi ma resini opangidwa, komanso ngati mankhwala ophera tizilombo toyambitsa matenda, polyformaldehyde ndi formaldehyde yolimba yokhala ndi formaldehyde yambiri, yomwe ili mu mawonekedwe a tinthu tolimba ndipo ndi yosavuta kusunga ndi kunyamula.

① Mankhwala ophera tizilombo: mankhwala ophera tizilombo opangidwa monga acetochlor, butachlor, ndi glyphosate;

② Utoto: utoto wa magalimoto wapamwamba kwambiri wopangidwa ndi opanga;

③ Utomoni: utomoni wa urea formaldehyde wopangidwa, utomoni wa phenolic, utomoni wa polyacetal, utomoni wa melamine, utomoni wosinthana wa ion, ndi zomatira zosiyanasiyana;

④ Kupanga mapepala: chothandizira kulimbitsa mapepala opangidwa;

⑤ Kuponya: chotsukira mchenga, guluu wopangira zinthu;

⑥ Ulimi wa ziweto: mankhwala ophera tizilombo toyambitsa matenda.

⑦ Zipangizo zachilengedwe: zimagwiritsidwa ntchito pokonzekera pentaerythritol, trimethylolpropane, glycerol, acrylic acid, methyl acrylate, methacrylic acid, N-hydroxymethylacrylamide, alkylphenol, methyl vinyl ketone, ndi zina zotero.

⑧ Zina: Mankhwala ndi kupha tizilombo toyambitsa matenda. Amagwiritsidwa ntchito ngati mankhwala ophera tizilombo toyambitsa matenda, opha tizilombo toyambitsa matenda, komanso ophera tizilombo toyambitsa matenda. Amagwiritsidwa ntchito popanga zinthu zachilengedwe komanso kupanga mankhwala.

3. Kusungirako:

Sungani m'nyumba yosungiramo zinthu yozizira komanso yopatsa mpweya. Khalani kutali ndi magwero a moto ndi kutentha. Kutentha kosungirako sikuyenera kupitirira 32 ℃, ndipo chinyezi sichiyenera kupitirira 80%. Iyenera kusungidwa padera ndi ma oxidants, ma reducers, ma acid, ma bases, ndi zina zotero, ndipo pewani kusakaniza malo osungiramo zinthu. Gwiritsani ntchito magetsi ndi zipangizo zopumira zomwe sizingaphulike. Letsani kugwiritsa ntchito zida ndi zida zamakanika zomwe zimayambitsa ma spark. Malo osungiramo zinthu ayenera kukhala ndi zipangizo zoyenera kusunga zinthu zomwe zimatuluka.
