Polyformaldehydeose fa'aputuga fau e ala i le polymerization o formaldehyde, ma o lona fa'aogaina e aofia ai le tele o fanua:
Alamanuia fanua
O le paraformaldehyde e masani ona faʻaaogaina i le gaosiga o le polyoxymethylene resin (POM), lea e sili ona lelei le faʻaogaina o le faʻaogaina ma mea faʻainisinia ma e talafeagai mo le gaosiga o vaega faʻainisinia saʻo (e pei o mea faʻaoga ma bearings).
I totonu o fale faʻapipiʻi ma faʻapipiʻi, e mafai ona faʻaleleia atili le faʻafefeteina o le vai ma le maaa o le oloa, ma faʻaaogaina i le gaosiga o fafie, fausiaina ma mea tau eletise. ?
1. Fa'ato'aga
O le Paraformaldehyde e faʻaaogaina e faʻapipiʻi ai vailaʻau (e pei o le glyphosate ma le acetochlor) ma iniseti (e pei o le tetramethrin ma le phorate), ma e faʻaaogaina foi e fai ma faʻamaʻi palapala i le gaosiga o vailaau faʻasaina. ?
2. Puipuiga o le siosiomaga
O le Paraformaldehyde e faʻaaogaina mo le faʻamamaina o le vai otaota ma le faʻamamaina o le ea
3. Mea fa'akomepiuta
Paraformaldehydee mafai ona faʻaaogaina e saunia ai resini phenolic, resins urea-formaldehyde, ma isi mea, e faʻaaogaina i mea fau fale, faʻapipiʻi mo mea eletise, ma faʻaleleia pepa. ?
I le avea ai o se vailaʻau faʻasolosolo taua, o le paraformaldehyde e masani ona faʻaaogaina i resini gaosia, paʻu, faʻapipiʻi, ma vailaʻau. I totonu o alamanuia, ua avea le paraformaldehyde ma mea taua mo le saunia o polyoxymethylene plastics (POM) ona o lona mama maualuga ma mautu vailaʻau. Afai ei ai ni ou manaʻoga faʻapitoa pe manaʻo e fia iloa atili e uiga i faʻamatalaga talosaga o le paraformaldehyde i vaega eseese, faʻamolemole faʻafesoʻotaʻi le Aojin Chemical. Matou te fiafia e tu'uina atu ia te oe fautuaga ma auaunaga fa'apitoa.
