Furniture pollution has become the third largest indoor environmental pollution after building pollution and decoration pollution. First of all, the wood should be treated with insects and mildew. In the process of molding the furniture, adhesives and paints should be used. If the harmful substances of these materials exceed the standard, it will also cause pollution.
Harmful gases in furniture, mainly formaldehyde, benzene, TVOC and other pollutants.
Formaldehyde is a colorless, easily soluble, irritating gas. Artificial boards, adhesives and wallpapers such as particleboard, MDF and plywood are the main sources of formaldehyde in the air, with a release period of 3 to 15 years. It can be absorbed through the respiratory tract, and the harm of formaldehyde to the human body has the characteristics of long-term, latent and concealed. Long-term inhalation of formaldehyde can cause serious diseases such as nasopharyngeal cancer and throat cancer.
Benzene is a colorless, gas with a distinctive aroma. Glues, paints, coatings and adhesives are the main sources of benzene in the air. When benzene and benzene are inhaled by the human body, central nervous system anesthesia can occur; it can inhibit the hematopoietic function of the human body, reduce red blood cells, white blood cells, thrombocytopenia, and increase the prevalence of aplastic anemia; it can also cause abnormal menstruation in women and congenital Defects, etc.
TVOC Total Volatile Organic Compounds, abbreviations for VOC and Votatile Organic Compound. VOCs are heterogeneous pollutants in indoor air. Because of their low concentration, there are many types, which are generally not indicated separately, and their total amount is represented by TVOC. TVOC includes benzene, toluene, butyl acetate, ethylbenzene, p-xylene, styrene, o-xylene, undecane and the like. Indoor building and decorative materials are the main source of TVOC in the air. Studies have shown that even if the content of individual VOC in indoor air is lower than its limit, the presence and interaction of various VOCs increases the damage intensity. TVOC shows toxicity and irritation, can cause imbalance of immune level, affect central nervous system function, dizziness, headache, lethargy, weakness, chest tightness and other symptoms, may also affect the digestive system, loss of appetite, nausea, etc. Damage to the liver and hematopoietic system, and even death.
Packaging machine for the production of various specifications of the packing belt. The machine is the main raw material of polyethylene and polypropylene resin, and it is made of nylon and polyester. Elastic plastic tape with good elasticity, high strength, good water resistance, chemical resistance, soft and soft, can be tied to the manual Strapping Machine. The utility model has the advantages of convenient use, low cost, and can be made into red, white, blue, yellow, green, and the like, and the goods of different grades are packed according to the color, which is convenient for distinguishing the grade of goods and improving the delivery efficiency.
