Ukuhlolwa kweebrashi zamazinyo zoMntwana

Ngenxa yokuba umngxuma womlomo wabantwana ukwinqanaba lophuhliso, ubuthathaka xa kuthelekiswa nendawo yomlomo yabantu abadala, nakwinqanaba lesizwe, umgangatho webrashi yamazinyo yomntwana ungqongqo ngakumbi kunebhrashi yamazinyo yabantu abadala, ngoko ke kuyimfuneko. abantwana basebenzise ibrashi yamazinyo yomntwana ekhethekileyo.

Xa kuthelekiswa nebhrashi yamazinyo yabantu abadala, ibhrashi yamazinyo yomntwana iya kuba nentloko encinci neguquguqukayo yebhrashi yamazinyo ukuze ingene nzulu emlonyeni kwaye icoce umphezulu wezinyo ngalinye.Ukongezelela, ukuze abantwana bangaginyi intlama yamazinyo eninzi, intlama yamazinyo idla ngokulingana neertyisi, yaye ubuso beebrashi zamazinyo zomntwana buyenzelwe ukuba zibe mxinwa.

Ke ngoko, ibhrashi yamazinyo yomntwana ifuna intloko yebhrashi yamazinyo encinci kwaye ibhityile, iibristles ezicolekileyo, kunye nomphezulu obhityileyo, olungele iintsana ezinomlomo omncinci kunye neentsini ezithambileyo.

Umgangatho wesizwe onyanzelekileyo,Iibrashi zamazinyo zabantwana(GB30002-2013), evunyiweyo kwaye ikhutshwe yi-AQSIQ kunye ne-Standardization Administration yaseChina iphunyezwe ngokusemthethweni ukususela ngo-Disemba 1, i-2014, enika isiseko esomeleleyo kunye nesiqinisekiso sokhuseleko kubathengi.

Ngokweemfuno zeUmgangatho omtsha, iinkcukacha ezicacileyo zenziwe kwiibrashi zamazinyo zomntwana kwiinkalo zeemfuno zococeko, iimfuno zokhuseleko, iinkcukacha kunye nobukhulu, amandla e-bundle, i-sueding, imihlobiso kunye nemeko yangaphandle yokuxhoma.

I-Antimony, i-barium kunye ne-selenium yongezwe kumda wezinto ezinobungozi kwisiseko se-arsenic, i-cadmium, i-chromium, i-lead kunye ne-mercury;

Iimfuno eziqhelekileyo:

Ubude bomphezulu webrashi yamazinyo buya kuba ngaphantsi okanye bulingane ne-29 mm;

Ububanzi be-bristle surface buya kuba ngaphantsi okanye bulingane ne-11 mm;

Ubunzima bentloko yebhrashi yamazinyo buya kuba ngaphantsi okanye bulingane ne-6 mm;

Ububanzi be-monofilament buya kuba ngaphantsi okanye bulingane no-0.18 mm;

Ubude obupheleleyo bebrashi yamazinyo buya kuba yi-110-180 mm.
