Sida loo xakameeyo haraaga dareeraha ah ee ku jira halbeegga aluminiumka cuntada lagu dahaadhay?

Fool Aluminium Dahaarka Cunto, faa'iidooyinka ay ku leedahay guryaha xannibaadda awgeed, daboolida kulaylka, iyo badbaadada, waxaa si weyn loogu isticmaalaa baakadaha cuntada. Haraaga dareeraha ah waxay inta badan ka yimaadaan dareerayaasha organic (sida ethyl acetate, methyl ethyl ketone, khamriga, taxanaha benzene, iwm.) loo isticmaalo dahaarka, daabacaad, iyo hababka lamination. Xadka dhaafka waxa ay sumayn kartaa cuntada, saameeya tayada dareenka, oo xataa waxyeelo u geysta caafimaadka. Xakamaynta haraaga dareeraha waxay u baahan tahay maaraynta xidhxidhan ee silsiladda oo dhan - laga bilaabo caanaha isha, xakamaynta habka, iyo maareynta deegaanka si loo tijaabiyo xaqiijinta-hubinta u hoggaansanaanta heerarka sida Rug 31604.60-2024 (Wadarta haraaga ≤5.0 mg/m², taxanaha benzene lama ogaan karo).

I. Ilaha iyo Khataraha Haraaga Xalka
