Description

technical field [0001] The invention relates to the technical field of laboratory materials, in particular to a heat-resistant and chemical-resistant laboratory table mat. Background technique [0002] At present, all places where experiments need to be done in schools, scientific research institutes, factories and mines generally require experimental benches, which are mainly used for placing items and performing experimental operations. Traditional experimental benches are generally wooden experimental benches, reinforced concrete (marble) experimental benches, metal experimental benches or physical and chemical board experimental benches. However, because the equipment in the laboratory needs to face a variety of experimental environments, the existing various experimental benches have certain limitations in the process of use, such as poor heat resistance and chemical resistance, and short service life. The application of the test bench is limited. [0003] The laborat...
