Polyformaldehydeo se vailaʻau na fausia e ala i le polymerization o le formaldehyde, ma o ona faʻaoga e aofia ai le tele o vaega:
Malae fa'apisinisi
E fa'aaogaina lautele le Paraformaldehyde i le gaosiga o le polyoxymethylene resin (POM), lea e sili ona tete'e i le ofuina ma e iai ona uiga fa'amekanika ma e talafeagai mo le gaosiga o vaega fa'amekanika sa'o (e pei o kia ma u'amea).
I totonu o pisinisi vali ma mea fa'apipi'i, o ona uiga fa'apipi'i e mafai ona fa'aleleia atili ai le tete'e atu i le vai ma le ma'a'a o le oloa, ma e fa'aaogaina i le gaosiga o la'au, faufale ma pisinisi eletise.
1. Fanua fa'ato'aga
E fa'aaogaina le Paraformaldehyde e fa'aputu ai vaila'au fa'asaina (e pei o le glyphosate ma le acetochlor) ma vaila'au fa'asaina iniseti (e pei o le tetramethrin ma le phorate), ma e fa'aaogaina fo'i o se vaila'au e fa'amamā ai le eleele i le gaosiga o vaila'au fa'asaina iniseti.
2. Malae puipuia o le siosiomaga
E faʻaaogaina le Paraformaldehyde mo le togafitia o vai otaota ma le faʻamamāina o le ea.
3. Mea fa'apitoa
Paraformaldehydee mafai ona fa'aaogaina e saunia ai phenolic resins, urea-formaldehyde resins, ma isi mea fa'apena, e fa'aaogaina i mea fau fale, mea fa'apipi'i mo vaega eletise, ma mea fa'aleleia pepa.
I le avea ai o se mea mata taua o vailaʻau faʻanatura, e faʻaaogaina tele le paraformaldehyde i resins faʻapitoa, ufiufi, mea faʻapipiʻi, ma vailaʻau. I le alamanuia, ua avea le paraformaldehyde ma mea mata taua mo le sauniaina o palasitika polyoxymethylene (POM) ona o lona mama maualuga ma lona mautu o meatotino faʻakemikolo. Afai ei ai ni ou manaʻoga faʻapitoa pe e te fia iloa atili e uiga i faʻamatalaga faʻaoga o le paraformaldehyde i matāʻupu eseese, faʻamolemole faʻafesoʻotaʻi Aojin Chemical. Matou te fiafia e tuʻuina atu ia te oe fautuaga ma auaunaga faʻapolofesa.
