Foshan Mattress Factory Introduction Formaldehyde (HCHO) is a colorless and soluble irritant gas. Long-term exposure to low-dose formaldehyde can cause slow respiratory diseases, while high-concentration formaldehyde is toxic to the nervous system, immune system, and liver. , and may lead to cancer of the nose, mouth, throat, skin and digestive tract. If a newborn is exposed to formaldehyde for a long time, it will cause physical decline, chromosomal abnormalities, and even cause children to suffer from leukemia. Whether the formaldehyde emission of the spring soft cushion is overrun is directly related to the safety and health of product users.

QB1952.2-2004 "Soft Furniture Spring Soft Cushion" refers to GB18587-2001 "Interior Decoration Materials Carpet, Carpet Liner and Carpet Adhesive Release Quantitative Release of Hazardous Substances" to request the amount of formaldehyde released, and stipulates that the amount of formaldehyde released should be ≤0.050mg/m2•h, the method is the small environmental experiment chamber method. The inspection results over the years show that the qualified rate of formaldehyde emission is more than 80%. The highest formaldehyde emission of unqualified products of Foshan Mattress Factory is as high as 1.866mg/m2•h, exceeding the standard permission requirements by more than 37 times. This project is related to everyone's life and health, and it is necessary to achieve 100% of the requirements.

There are three main sources of formaldehyde in the mattress: (1) The foam plastic and chemical fiber felt used in the mattress are sprayed with adhesive during treatment, and the adhesive is rich in a certain amount of formaldehyde. Although Foshan Mattress Factory now has formaldehyde-free adhesive, but The price is generally high, and most manufacturers will not use it; (2) The dyes, anti-wrinkle agents, preservatives and other auxiliaries added to the fabric of the mat are rich in formaldehyde, and it is very easy for manufacturers to use formaldehyde-rich auxiliaries to treat the fabric It is easy to make the formaldehyde overrun of the fabric; (3) The formaldehyde overrun is particularly serious when coconut palm or mountain palm is used as bedding material. Blindly participating in a lot of adhesives, although the physical properties of the brown flakes have been improved, the continuous release of formaldehyde from the adhesives has caused formaldehyde overruns. Over the years, government regulators have continued to increase commodity inspections and punish unqualified companies. With the continuous improvement of consumers' awareness of environmental protection, when choosing spring soft cushions, the most important thing is generally the environmental protection function of the product.

Therefore, whether it is from the perspective of government regulation or market demand, it is imperative for every company to pay attention to the environmental protection quality of spring soft cushions. This article is collected by Foshan Mattress Factory.
