Polyformaldehydeikemikari inoumbwa ne polymerization ye formaldehyde, uye mashandisirwo ayo anofukidza nzvimbo dzakawanda:
Munda wemaindasitiri
Paraformaldehyde inoshandiswa zvakanyanya mukugadzira polyoxymethylene resin (POM), iyo inodzivirira kupfekwa zvakanaka uye ine hunhu hwakanaka hwemakanika uye yakakodzera kugadzira zvikamu zvemakanika zvakanyatsonaka (senge magiya nemabheringi).
Mumaindasitiri ekuputira nekunamira, hunhu hwayo hwekubatanidza zvinhu zvinogona kuvandudza kusimba kwemvura uye kuoma kwechigadzirwa, uye inoshandiswa mumaindasitiri ekugadzira huni, kuvaka uye zvemagetsi.
1. Munda wekurima
Paraformaldehyde inoshandiswa kugadzira mishonga yekuuraya zvipembenene (yakadai seglyphosate neacetochlor) uye mishonga yekuuraya zvipembenene (yakadai setetramethrin nephorate), uye inoshandiswawo semushonga wekuuraya zvipembenene muvhu mukugadzira mishonga yekuuraya zvipembenene.
2. Nzvimbo yekudzivirira zvakatipoteredza
Paraformaldehyde inoshandiswa pakuchenesa mvura yakasviba uye kuchenesa mweya.
3. Zvinhu zvakagadzirwa nemakemikari
Paraformaldehydeinogona kushandiswa kugadzira maresini ephenolic, maresini eurea-formaldehyde, nezvimwewo, zvinoshandiswa mukuvaka, zvinonamira zvezvikamu zvemagetsi, uye zvinosimudzira mapepa.
Sechinhu chakakosha chemakemikari emuchadenga, paraformaldehyde inonyanya kushandiswa mumaresini ekugadzira, machira, manamati, nemishonga. Muindasitiri, paraformaldehyde yave chinhu chakakosha chekugadzira mapurasitiki epolyoxymethylene (POM) nekuda kwekuchena kwayo kwakanyanya uye hunhu hwayo hwemakemikari hwakagadzikana. Kana uine zvaunoda kana kuti uchida kuziva zvakawanda nezvekushandiswa kweparaformaldehyde muminda yakasiyana-siyana, ndapota taura neAojin Chemical. Tinofara kukupa mazano ehunyanzvi uye masevhisi.
