Many people ask, is the smell of asphalt volatilization toxic? In fact, there is certain toxicity. But it has little impact on the human body, so how long can the taste disappear? Next, Jinan asphalt manufacturer will explain it to you.
Asphalt is a kind of waterproof, moisture-proof and anti-corrosion organic cementing material. Asphalt can be mainly divided into coal tar asphalt, petroleum asphalt and natural asphalt. Among them, coal tar asphalt is a by-product of coking.
Petroleum asphalt is the residue of crude oil distillation. Natural asphalt is stored underground, and some forms ore beds or accumulates on the surface of the crust. Asphalt is mainly used in coating, plastic, rubber and other industries as well as pavement.
The smell of asphalt volatilization is toxic. During paving, asphalt will emit gas due to high temperature, which can also be called "asphalt smoke". These gases contain many substances harmful to human health, which will easily cause human poisoning.
Although the unpleasant smell volatilized by asphalt during paving is toxic, the gas volatilized by asphalt roads officially put into use at room temperature after asphalt cooling is completed, which has little impact on human body.
It takes about one week in case of ventilation, and 2-3 weeks in case of poor re ventilation. Asphalt is a dark brown complex mixture composed of hydrocarbons with different molecular weights and their non-metallic derivatives. It is a kind of high viscosity organic liquid, liquid, black on the surface, and soluble in carbon disulfide.
