Waxaa hubaal ah waa in line heerka weelka qaranka Melamine Dinnerware, aad aw kartaa in melamine iyo falcelin formaldehyde in ay soo saaraan wax melamine, reaction reaction karin, oo aan mar kale soo celin doonaan melamine ama formaldehyde, laakiin falcelin this, formaldehyde waa xad-dhaaf ah ( xaaladaha reaction loo baahan yahay), taasoo keentay in dareen-celinta ka dib markii dhamaadka qadar yar oo ah formaldehyde lacag la'aan ah wax ku, laakiin habka follow-up of baaraandegidda qaar ka mid ah formaldehyde free sii daayo qayb ka mid ah, waxaa weli jira qayb ka mid ah jiritaanka waxyaabaha, imtixaanka baxday (socdaalka formaldehyde free in ka yar 15 ㎎ / ㎏, Heerka Midowga Yurub), awoodo sida badeecadaha a, miiska soo geliyey aad.
Xinhua News Agency, Medical Association American ah, "Daawo Medical" magazine ayaa dhawaan la daabacay warbixinta cilmi-baadhis ah in melamine qalab dihin ee wax soo saarka ee weelka ee geedi socodka heerkulka sare, sii daayo walxaha kiimikada, cunto galay jidhka bini'aadamka.
Cilmibaadhayaasha ayaa la doortay laba kooxood oo ka mid ah ragga weyn ee caafimaad qaba iyo haweenka sida shayga waxbarasho, siday u kala horreeyaan, si ay u isticmaalaan baaquli melamine oo kan maddiibad dhoobada isticmaalka cuntada. 12 saacadood gudahood ah wax cunaya, cilmi baaro baarka kaadida ay.
Natiijooyinku waxay muujisay in isticmaalka group Melamine Dinnerware maadooyinka, content melamine celcelis ahaan kaadida waa koox kale oo 6.4 jeer.
Baadhitaanka ayaa lagu ma qiimeeyo saamaynta melamine on caafimaadka dadka, ka cuno ee melamine waa dhibaato muddo dheer caafimaadka dadka aan la xaqiijin karo. Khubarada ayaa tilmaamay in shaqada kelyaha dhallaanka weli waa daciif, sidaa darteed muddo dheer dose hooseeyo qaadashada of melamine si fudud u dhaawici ay function kelyaha.
Melamine waa xarunta ah organic, si ballaaran loo isticmaalo in blaastiigga, bacyaal, daawooyinka, dharka iyo beeraha kale. Sida alaabta qabow iyo kulayl iska caabin waa wanaagsan yahay, anti-dhibic waara, ma fududa in la libdhi, melamine sida wax ugu weyn ee cayriin ee weelka galaas daydaan.
Cilmi ayaa sheegay in bulshada caafimaad on melamine keeni karta in muddo dheer effects noolaha u baahan tahay in ay sii wadaan cilmi-baarista.
Cusbi formaldehyde Melamine laftiisa waa non-sun ah, laakiin cusbi formaldehyde melamine ku jira xaddi gaar ah oo formaldehyde free, in shucaaca microwave uu noqon doono gaabis ah in ay sii daayaan, si nabadgelyada, isticmaalka cusbi melamine maacuunta lagu sameeyo waxaa la qorayaa "karaa ma waxaa lagu shubaa microwave ah "digniin niyadsamida The. Laakiin nasiib daro: Sida ay jeegaga rigoore, qiimaha suuqa ee 13,000 in 14,000 yuan / ton ee wax dumin kara melamine soo saarka ee saboolka ah weelka galaas oo tayo leh ka yar 20%. Iyadoo qiimaha 5,000 yuan / ton of dumin kara HOL-formaldehyde halkii, wax soo saarka ku dhowaad sharci-darrada ah ee warshadaha weelka galaas Bare "xeerarka qarsoon."
Cusbi HOL-formaldehyde (ee Ismaamulka)
dumin kara khal HOL (ie HOL formaldehyde cusbi) waa HOL iyo formaldehyde by daray reaction polymerization of dumin kara thermosetting ah. Dhismaha ee alaabta waa mid adag, si toos ah inta of HOL iyo formaldehyde, pH nidaamka falcelinta, heerkulka reaction, waqti iyo xaalado kale. Cusbi HOL-formaldehyde The, kaas oo uu ku dhexsameeysmo by Aragti dhaqameedka, waxaa inta badan u kala qaybiyey laba marxaladood. Heerka koobaad waa formation of HOL methylol, taas oo ah marxalad reaction dheer. The cusbi marxaladda labaad waa heerka reaction polycondensation ah.
