PolyformaldehydeNdi gulu lopangidwa ndi polymerization ya formaldehyde, ndipo ntchito zake zimaphimba madera angapo:
Munda wa mafakitale
Paraformaldehyde imagwiritsidwa ntchito kwambiri popanga utomoni wa polyoxymethylene (POM), womwe umakhala ndi kukana kovala bwino komanso makina amakina ndipo ndi oyenera kupanga zida zamakina zolondola (monga magiya ndi ma fani).
M'mafakitale opaka ndi zomatira, zinthu zake zogwirizanitsa zimatha kupititsa patsogolo kukana kwa madzi ndi kuuma kwa mankhwala, ndipo zimagwiritsidwa ntchito popanga nkhuni, zomangamanga ndi zamagetsi. pa
1. Munda waulimi
Paraformaldehyde imagwiritsidwa ntchito popanga mankhwala a herbicides (monga glyphosate ndi acetochlor) ndi mankhwala ophera tizilombo (monga tetramethrin ndi phorate), ndipo amagwiritsidwanso ntchito ngati mankhwala ophera tizilombo m'nthaka popanga mankhwala ophera tizilombo. pa
2. Malo oteteza zachilengedwe
Paraformaldehyde imagwiritsidwa ntchito poyeretsa madzi oyipa komanso kuyeretsa mpweya
3. Zipangizo zopangira
Paraformaldehydeangagwiritsidwe ntchito pokonza utomoni wa phenolic, urea-formaldehyde resins, ndi zina zotero, zomwe zimagwiritsidwa ntchito pomanga, zomatira pazinthu zamagetsi, ndi zowonjezera mapepala. pa
Paraformaldehyde imagwiritsidwa ntchito kwambiri popanga utomoni wopangira, zokutira, zomatira, ndi mankhwala. M'makampani, paraformaldehyde yakhala yofunika kwambiri pokonzekera mapulasitiki a polyoxymethylene (POM) chifukwa cha kuyera kwake komanso kukhazikika kwa mankhwala. Ngati muli ndi zosowa zapadera kapena mukufuna kudziwa zambiri za kagwiritsidwe ntchito ka paraformaldehyde m'malo osiyanasiyana, lemberani Aojin Chemical. Ndife okondwa kukupatsani upangiri waukadaulo ndi ntchito.
