Polyformaldehydehe matū i hangaia mā te whakapūhuitanga o te formaldehyde, ā, he maha ngā mara e whakamahia ana e ia:
Mara ahumahi
E whakamahia whānuitia ana te paraformaldehyde i roto i te hanga kapia polyoxymethylene (POM), he tino ātete ki te kakahu me ōna āhuatanga hangarau, ā, he pai hoki mō te hanga wāhanga hangarau tino tika (pērā i ngā taputapu me ngā peera).
I roto i ngā ahumahi paninga me te piri, ka taea e ōna āhuatanga honohono te whakapai ake i te ātete wai me te pakeke o te hua, ā, ka whakamahia hoki i roto i ngā ahumahi tukatuka rakau, hanga me te hikohiko.
1. Mara ahuwhenua
Ka whakamahia te paraformaldehyde hei hanga i ngā patu taru (pērā i te glyphosate me te acetochlor) me ngā patu pepeke (pērā i te tetramethrin me te phorate), ā, ka whakamahia hoki hei patu huakita oneone i roto i te hanga patu pepeke.
2. Mara tiaki taiao
Ka whakamahia te paraformaldehyde mō te maimoatanga wai para me te purenga hau
3. Ngā rauemi hangai
Paraformaldehydeka taea te whakamahi hei hanga i ngā kapia phenolic, ngā kapia urea-formaldehyde, me ētahi atu, e whakamahia ana i roto i ngā rauemi hanga, ngā piripiri mō ngā wāhanga hiko, me ngā whakarei pepa.
Hei rauemi mata matū waro nui, ka whakamahia te paraformaldehyde i roto i ngā kapia hangai, ngā paninga, ngā piripiri, me ngā rongoā. I roto i te ahumahi, kua noho te paraformaldehyde hei rauemi mata nui mō te whakarite i ngā kirihou polyoxymethylene (POM) nā te mea he tino parakore me ōna āhuatanga matū pumau. Mena he hiahia motuhake āu, he hiahia rānei ki te mōhio atu mō ngā taipitopito tono o te paraformaldehyde i roto i ngā momo mara, tēnā whakapā atu ki a Aojin Chemical. E harikoa ana mātou ki te whakarato tohutohu me ngā ratonga ngaio ki a koe.
