How do I distinguish between calcium silicate boards and asbestos?
I heard some people use cement board instead of calcium silicate board, containing asbestos ingredients!
Asbestos fiber cement products for interior and exterior decorations and indoor ceilings, the fine asbestos fibers contained in the light, if they are inhaled, may cause refractory asbestos lung disease, which can cause various cancers and bring great (Such as Germany, France, Sweden, Singapore, etc.) has banned the production and use of all asbestos products.China has also some companies began to produce non-asbestos cement sheet.Therefore, in the decoration of the house, in the Conditions permitting, the choice of non-asbestos cement products is better.
Asbestos harm to the human body:
Asbestos itself is not toxic, its greatest harm comes from its fiber, which is a very small, almost invisible fibers, when these small fibers can be released after a long time floating in the air, was inhaled into the body, Inhaled asbestos fibers can accumulate in the human body for many years, attached and deposited in the lungs, causing lung disease.
Asbestos is a fiber structure of silicate, in the building materials industry, mainly used for insulation materials and certain building materials, such as asbestos cement products, reinforced materials.
Asbestos is a natural fibrous siliceous mineral of the generic term, is widely used in building materials fire board silicate mineral fiber, is also the only natural mineral fiber, it has good tensile strength and good heat insulation (Asbestos), asbestos (brown asbestos) and crocidolite (blue asbestos), of which the content of chrysotile asbestos (asbestos), asbestos (asbestos) The most abundant, the most widely used.
