Huafu Chemicalo lo'o fa'asoa atu nisi o fa'amatalaga fa'apolofesa fa'ata'ita'iga ile femalaga'iga formaldehyde ile vevela maualuga e uiga ile melamine tableware.
Metotia o Su'ega: fa'asusu le 3% acetic acid solution i vevela eseese mo le 0.5 itula, 2 itula.Va'ai i le i'uga o lo'o i lalo.
A'afiaga o le fa'afefeteina o le vevela ile femalagaiga o formaldehyde mg/kg

E tusa ai ma le fuainumera,o ituaiga e tolu o ipu laulau e matua leai se formaldehyde monomer migration i lalo ole tulaga malulu e teu ai.
* I le 40 ℃, o le femalagaiga o formaldehyde mai ituaiga e tolu o meaʻai laulau e itiiti ifo i le 5 mg / kilokalama, ma le tapulaa faʻatulafonoina i le EU e 15 mg / kg.
* I le 80 ℃ ma luga atu, o le femalagaiga o formaldehyde e sili atu nai lo le tapulaa faʻatonuina.A'o fa'atupula'ia le vevela o le faatofu, e fa'atupula'ia tele le aofa'i o femalagaiga.
* I le 80 ℃, o le aofaʻi o femalagaiga o formaldehyde e faʻaalia ai se faʻalavelave faʻafuaseʻi, e oʻo atu i le maualuga ile 100℃.
O fa'ai'uga fa'ata'ita'iga e fa'aalia ai e fa'atupula'ia le vevela o le fa'atofuina, fa'atupula'ia le tikeri fa'atasi, fa'aitiitia le mafiafia o luga, ma fa'aitiitia le iila.O leamelamine laulau e fa'asaina microwave.E mafai ona matou fa'aogaina le kapoti fa'ama'i fa'ama'i osone po'o vai fa'ama'i fa'ama'i.
Ia, seʻi o tatou vaʻavaʻai i faʻamatalaga suʻega o Huafu melamine disk.Melamine fa'afefiloigaosia e Huafu Chemicals ua pasiaSGSsu'ega, e o'o lava i tulaga lelei.Afai o oe o fale gaosi laulau, faʻamolemole lagona le saoloto e faʻafesoʻotaʻi i matou mo tau sili ona lelei ma faʻamatalaga saoloto.
