Qalabka miiska ee Melamine waa nooc ka mid ah alaabta miiska oo leh khataro badbaado.Sababtoo ah maaddooyinka aan u qalmin, melamine tableware waxay la kulmi doonaan dhibaatooyin.Dhab ahaantii, agabka miiska melamine-ku waa mid lagu dabaqi karo "Heerka Fayadhowrka ee Melamine-Formaldehyde Samaynta Alaabta Cuntada iyo Qalabka Baakadaha".Waa maxay maaddooyinka ay tahay in lagu calaamadiyo alaabta miiska melamine?
"Heerarka Fayadhowrka ee Isticmaalka Wax-ku-darka ee Weelka Cuntada iyo Qalabka Baakadaha" ayaa la hirgeliyay Juun 1 2016. Waxay qeexaysaa inalaabta ceeriin ee melamine-formaldehyde resin(sida, melamine resin) waa in aanu sii deyn walxaha waxyeelada u leh caafimaadka marka loo eego shuruudaha isticmaalka;ogaanshaha tilmaamayaasha jirka iyo kiimikaad fayadhowr, Go'aaminta tirada socdaalka ee melamine monomer waa la kordhiyay.
Si loo calaamadiyo alaabta miiska melamine, thealaabta ceeriin ee alaabta miiskasi cad ayaa loogu baahan yahay markii ugu horeysay, iyo "darajada cuntada" iyo "kuleylinta foornada microwave-ka mamnuuc" waa in la ogeysiiyaa.Baakadaha dibadda ayaa si cad loogu baahan yahay in lagu calaamadiyo "darajada cuntada" iyo soo saaraha, magaca alaabta, shuruudaha isticmaalka, noocyada alaabta, iwm.
Heerka, unugga tilmaamayaasha jirka iyo kiimikaad hadhaaga uumiga, isticmaalka potassium permanganate, birta culus, iyo socdaalka monomer formaldehyde ayaa dib loo eegay ra9/L (mg/L) ilaa m9/dm2 (mg/dm2).Waxa ay khubaradu tilmaameen in heerkani uu u dhigmo 15m9/L, kaas oo laba jibaar ka adag kii hore ee 30m9/L.Urea-formaldehyde resin ee "cuntada sunta ah ee sunta ah" ee qalalaasaha oo hore u helay dareen badan, khubarada ayaa sheegay in labada heer ee kor ku xusan aysan ku jirin baaxadda isticmaalka.
Si kastaba ha ahaatee, Ururka Warshadaha Balaastigga ee Shiinaha ayaa shir jaraa'id qabtay dhawaan, iyagoo sheegay in qalabka loo yaqaan 'uremic resin-coated melamine resin tableware' uu sidoo kale yahay mid badbaado leh, wuxuuna ugu baaqay gobolka inuu horumariyo heerarka ku habboon.
