Kodi Paraformaldehyde CAS 30525-89-4 ndi chiyani?

Polyoxymethylene (POM) ndi polima wa formaldehyde (mkulu molekyulu kulemera polyoxymethylene) ndi mmene structural kutalika 8 mpaka zana limodzi malo. Utali wautali wa polyoxymethylene umagwiritsidwa ntchito popanga mapulasitiki osagwira kutentha, omwe amadziwikanso kuti polyoxymethylene mapulasitiki (POE, Derlin opangidwa ndi DuPont). Polyformaldehyde imawola mwachangu ndipo imatulutsa formaldehyde wonunkhiza pang'ono.

Kugwiritsa ntchito

1. Sinthani mphamvu zakuthupi mu labala, zokutira, ndi zomatira.

2. Kuphera tizilombo toyambitsa matenda ndi anti-corrosion, zomwe zimagwiritsidwa ntchito potsekereza minda, ma laboratories, ndi zida zamankhwala.

3. Ulimi, womwe umagwiritsidwa ntchito popha tizilombo toyambitsa matenda m'nthaka, kuchiritsa mbewu, ndi kuletsa mafangasi ndi mabakiteriya. Kupanga mankhwala ophera tizilombo ndi fungicides.

4. Kupititsa patsogolo kukana makwinya ndi kutentha kwamoto kwa nsalu. Iletsa kukula kwa tizilombo m'madzi ozungulira m'mafakitale.
