PolyformaldehydeNdi chinthu chomwe chimapangidwa ndi polymerization ya formaldehyde, ndipo ntchito zake zimaphimba magawo angapo:
Munda wa mafakitale
Paraformaldehyde imagwiritsidwa ntchito kwambiri popanga polyoxymethylene resin (POM), yomwe imakhala ndi mphamvu zabwino kwambiri zopewera kukalamba komanso mphamvu zamakanika ndipo ndi yoyenera kupanga zida zamakanika zolondola (monga magiya ndi mabearing).
Mu mafakitale opaka ndi zomatira, mphamvu zake zolumikizira zimatha kupititsa patsogolo kukana madzi ndi kuuma kwa chinthucho, ndipo chimagwiritsidwa ntchito m'mafakitale opangira matabwa, zomangamanga ndi zamagetsi.
1. Munda waulimi
Paraformaldehyde imagwiritsidwa ntchito popanga mankhwala ophera udzu (monga glyphosate ndi acetochlor) ndi mankhwala ophera udzu (monga tetramethrin ndi phorate), ndipo imagwiritsidwanso ntchito ngati mankhwala ophera udzu m'nthaka popanga mankhwala ophera udzu.
2. Malo oteteza zachilengedwe
Paraformaldehyde imagwiritsidwa ntchito poyeretsa madzi otayira komanso kuyeretsa mpweya.
3. Zipangizo zopangira
Paraformaldehydeingagwiritsidwe ntchito pokonza ma resins a phenolic, ma resins a urea-formaldehyde, ndi zina zotero, zomwe zimagwiritsidwa ntchito popanga zipangizo zomangira, zomatira zamagetsi, ndi zowonjezera mapepala.
Monga mankhwala ofunikira achilengedwe, paraformaldehyde imagwiritsidwa ntchito kwambiri mu utomoni wopangidwa, zokutira, zomatira, ndi mankhwala. M'makampani, paraformaldehyde yakhala chinthu chofunikira kwambiri chopangira mapulasitiki a polyoxymethylene (POM) chifukwa cha kuyera kwake kwakukulu komanso mphamvu zake zokhazikika za mankhwala. Ngati muli ndi zosowa zinazake kapena mukufuna kudziwa zambiri za momwe paraformaldehyde imagwiritsidwira ntchito m'magawo osiyanasiyana, chonde lemberani Aojin Chemical. Ndife okondwa kukupatsani upangiri ndi ntchito zaukadaulo.
