9. Iyada oo ah wax lagu daro soo saarista agabka shaabadaynta iyo suufka biriiga, waxay door ka ciyaartaa kordhinta iska caabbinta xirashada;
10. Sida waxyaabaha lagu daro ee sibidhka, kor u qaad iska caabbinta daxalka ee sibidhka.
Ka taxadaritaan:
1. Isticmaal sodium fluoride si aad si adag u xakamayso xaddiga fluorine-ka maalin kasta si looga hortago soo saarista sumowga fluoride;
2. Xalka Sodium fluoride ama jel waa in lagu ridaa weel balaastig ah;
3. Bukaanada, haweenka uurka leh, haweenka nuujinaya, jilicsanaanta lafaha iyo cilladaha kelyaha ee meelaha ay ku badan tahay fluoride waa mamnuuc.
Baakaynta iyo kaydinta
Habka Baakaynta:Bacaha balaastikada ah ama bacaha warqadda maqaarka lo'da ee laba lakab leh oo leh foosto loox fiilooyin dibadda ah, foosto loox alwaax ah, foosto loox warqad adag ah; foosto balaastig ah (adag) oo dibadda ah oo bacaha balaastikada ah; foosto balaastig ah (dareere ah); laba lakab oo bacaha balaastikada ah ama bac balaastig ah oo hal lakab ah oo dibadda ah oo bacaha dibadda ah, tolid balaastig ah, tolid balaastig ah oo balaastig ah Bacaha, bacaha latex; bacaha balaastikada ah ee isku dhafan ee balaastikada ah ee isku dhafan (polypropylene saddex-in-hal bac, bacaha saddex-in-hal polyethylene, bacaha laba-in-hal polyethylene, bacaha laba-in-hal polyethylene); bacaha balaastikada ah ama bacaha warqadda maqaarka ah ee laba lakab ah oo dibadda ah oo dibadda ah oo ka samaysan sanduuq alwaax caadi ah; dhalada galaaska dunta, dhalada galaaska ee daboolka birta ah, dhalada balaastikada ah ama foosto bir ah (qasacad) oo caadi ah oo ka samaysan alwaax; dhalada galaaska dunta, dhalada balaastikada ah ama qasacad - dahaaran foosto bir ah oo khafiif ah oo lagu dahaadhay (qasacad) Sanduuqa, sanduuqa fiberboard ama sanduuqa plywood. Baakadaha alaabta: 25kg/bac.
Taxaddarrada kaydinta iyo rarista:Inta lagu jiro gaadiidka tareenka, miiska xamuulka ee khatarta ah waa in lagu rakibaa si adag iyadoo la raacayo Xeerarka Gaadiidka Xamuulka ee Khatarta ah ee Wasaaradda Tareenada. Kahor inta aan la rarin, hubi in weelka baakadaha uu dhammaystiran yahay oo la shaabadeeyey. Inta lagu jiro rarista, waa inuu hubiyaa in weelku uusan daadan, dumin, dhicin, ama dhaawacmin. Waa mamnuuc in lagu qaso aashitada, oksaydhka, cuntada iyo waxyaabaha lagu daro cuntada. Inta lagu jiro rarista, gawaarida gaadiidku waa inay ku qalabaysan yihiin qalab daaweyn degdeg ah oo daadanaysa. Inta lagu jiro rarista, qorraxda iyo roobka waa in la soo bandhigaa si looga hortago heerkulka sare. Ku kaydi bakhaar qabow, qalalan, oo hawo leh. Heerkulka maktabadda kama badna 30 ° C, qoyaanka qaraabo ahna kama badna 80%. Baakad oo shaabadaysan. Ka kaydi si gaar ah kiimikooyinka aashitada iyo kuwa la cuni karo, iska ilaali isku darka. Meesha kaydinta waa inay lahaataa agabka ku habboon si loo xakameeyo daadanaysa. Si adag u hirgeli nidaamka maaraynta "shan labanlaab ah" ee walxaha sunta ah.
