Tuubbo nuugid iyo tuubbo nuugid heer cunto ah
Tuubbo nuugid iyo tuubbo dheellitiran oo heer sare ah oo FDA ahwaxay ku habboon tahay caanaha, casiirka miraha, cabitaannada fudud, biirka, khamriga, daawooyinka, qurxinta iyo cuntooyinka kale ee aan saliidda lahayn. Tuubada waxaa laga sameeyay isku-darka caagga ah ee heerkulka sare leh kaas oo buuxiya heerarka 3-A, Waaxda Beeraha ee Mareykanka (USDA), iyo Maamulka Cuntada iyo Dawooyinka (FDA) ee maaraynta cuntada. Waxay leedahay god siman oo dhiirrigeliya heerarka socodka ugu badan wuxuuna joojiyaa koritaanka bakteeriyada. Daboolka waxaa laga sameeyay nitrile cawlan oo la isku dhejiyay si loo helo dabacsanaan iyo iska caabin kiimikooyinka, kulaylka, iyo gabowga. Waxaa loo isticmaali karaa noocyo kala duwan oo ikhtiyaarro isku xiran ah (kuma jiraan). Isku-darka Tuubada Bixinta Cuntada wuxuu ku habboon yahay codsiyo badan oo warshadaha cuntada iyo cabitaanka ah.
Dhismaha Tuubada nuugista iyo soo saarista heerka FDA:
Tuubo:Cad, siman, NR, NBR ama caag tayo cunto leh oo EPDM ah
Xoojinta:Dhar macmal ah oo xoog badan.
Daboolka:siman (dhammaystir duuban), caag macmal ah, buluug ama caddaan, oo u adkaysta cimilada.
Codsiga Tuubada nuugista iyo soo saarista heerka FDA:
Tuubada cuntada ee FDA ay ansixisay oo loogu talagalay keenista cuntooyinka sida caanaha, casiirka, biirka, saliidda la cuni karo, waxyaabaha maalinlaha ah iwm.
Waxaa lagu taliyay codsiga wareejinta cuntada ee u baahan dabacsanaan iyo adkaysi labadaba iyadoo la isticmaalayo tuubo cad oo nadiif ah oo heerka FDA ah.
Tuubada nitrile-ka ee heerka cuntada ah waa mid aan ur lahayn oo aan dhadhan lahayn codsiyada wareejinta saliidda leh. Aad ugu fiican codsiyada sii deynta.
Tuubadan oo aad u siman oo u adkaysta microbe-ka ayaa lagu dhisay bir bir ah oo gaar ah oo aan miridh lahayn si loo nadiifiyo.
