Many dust related enterprises, such as feed processing plants, paper processing plants, etc., do not know whether the relevant workshops belong to explosive workshops and whether they need toZhongnuo TestingTake relevant dust explosion prevention measures, and at this time, consider using designated samples from the dust workshop for productionDust explosionRelevant tests have been conducted.
