ʻO kahi hana hoʻomākaukau no ka formaldehyde-manuahi a me ka paʻa-paʻa sodium bisulfite formaldehyde

Hōʻike ka ʻatikala i kahi ʻano hoʻomākaukau no ka formaldehyde-free a me ka mālama ʻana-stablerongalite, ʻo ia nā ʻanuʻu o ka hoʻohui pū ʻana i ka sodium metabisulfite, ka pauka zinc, ka catalyst a me ka formaldehyde i loko o kahi ʻōnaehana hopena e loaʻa ai ka solution asodium formaldehyde sulfoxylate.

Hoʻohui ʻia nā pūhui Polyphenol a me ka desiccant i ka hoʻonā e loaʻa ai kahi ʻano hui like ʻole a paʻa ka sodium formaldehyde sodium sulfoxylate storage solution, a hope loa a hoʻomaloʻo ʻia no ka loaʻa ʻana o ka formaldehyde-free a me ka mālama-stablerongalite.

Hoʻomākaukau ʻia ka sodium formaldehyde sulfoxylate ma ka hoʻohana ʻana i kahi ʻano hana hoʻokahi, a loaʻa ka formaldehyde-free a me ka mālama-stablerongalite ma ka hoʻohui ʻana i kahi pūhui polyphenol a me ka gel silica.

Hoʻomaopopo ke ʻano hana i ke ʻano haʻahaʻa haʻahaʻa haʻahaʻa hoʻokahi no ka hoʻomākaukau ʻana i ka therongalite ʻaʻole formaldehyde manuahi a paʻa i ka mālama ʻana, ke ala e hōʻemi ai i ka mahana o ka hopena a me ka manawa pane e pono ai no ka hoʻomākaukau ʻana i ka formaldehyde sodium sulfoxylate, mālama i ka hoʻohana ʻana i ka ikehu a me ka manawa, hoʻomaikaʻi i ka hana pono. , ho'ēmi i ke kumu kūʻai, a ʻaʻole ka formaldehyde manuahi i hoʻomākaukau ʻia a hoʻomaikaʻi nui i ka paʻa o ka mālama ʻana.

ʻO ka hana ʻana o ka sodium bisulfite formaldehyde e kēia ʻano hana he ʻekolu mau kaʻina nui: ka hoʻohaʻahaʻa hoʻohaʻahaʻa hoʻohui i ka hopena, ka hoʻokaʻawale ʻana i ka wai a me ka evaporation a me ka crystallisation.
