Raws li daim duab,peb hom tableware yeej tsis muaj formaldehyde monomer tsiv teb tsaws nyob rau hauv txias cia txias.
* Ntawm 40 ℃, kev tsiv teb tsaws ntawm formaldehyde los ntawm peb hom tableware tsawg dua 5 mg / kg, thiab cov kev txwv hauv EU yog 15 mg / kg.
* Ntawm 80 ℃ thiab siab dua, kev tsiv teb tsaws ntawm formaldehyde zoo heev tshaj li qhov txwv.Raws li lub immersion kub nce, tus nqi ntawm kev tsiv teb tsaws nce heev.
* Ntawm 80 ℃, qhov kev tsiv teb tsaws ntawm formaldehyde qhia tau tias muaj kev nce ntxiv, mus txog qhov siab tshaj plaws ntawm 100 ℃.
Qhov kev sim ua kom pom tias cov kev nce qib kev nce ntxiv, kev sib cais;Yog limelamine tableware yog microwave txwv tsis pub.Peb tuaj yeem siv ozone disinfection txee lossis tshuaj tua kab mob ua kua.
Tam sim no, cia peb saib cov ntaub ntawv ntsuas ntawm Huafu melamine disc.Melamine molding compoundtsim los ntawm Huafu Chemicals tau dhau lawmSGSkuaj, txawm zoo heev nyob rau hauv zoo.Yog tias koj yog tableware factories, thov koj xav tiv tauj peb rau tus nqi zoo tshaj thiab cov ntaub ntawv dawb.
