A complete set of formaldehyde equipment to control the various sources of odor in the home

Formaldehyde stimulated mucous membrane

Free formaldehyde is the focus of attention. At present, formaldehyde is the raw material for the manufacture of synthetic resins, paints, plastics and artificial fibers. It is an important raw material for the manufacture of urea formaldehyde resin adhesive and cyanogen resin adhesive in the wood-based panel industry. Materials used in interior decoration or furniture, such as plywood, woodworking board, medium density fiberboard, particleboard, wallpaper, wallpaper, chemical fiber carpets, paint, paint, adhesives, etc., contain formaldehyde or a chemical that can be hydrolyzed to formaldehyde. These residual or decomposed formaldehyde will gradually release to the surrounding environment, the longest release period can be more than ten years.

Chronic poisoning of formaldehyde is characterized by tears, itching, throat dryness, itching, cough, asthma, hoarseness, chest tightness, pruritus and so on. Previous studies have shown that long term low dose exposure can lead to lower body immune function, neurasthenia, memory impairment, chronic respiratory irritation, chronic respiratory disease, and decreased lung function.

The smell of ammonia is very sharp

Ammonia is mainly derived from concrete admixtures in building materials. In winter construction, concrete and urea are added to the concrete wall to protect the concrete from freezing. These additives can be reduced to ammonia and released slowly from the wall with the change of environmental factors in the wall, resulting in an increase in ammonia concentration in indoor air. The second is the additive and whitening agent in the interior decoration material: the wood board containing the adhesive of the urea component, the coating with the ammonia water as the additive and the brightener.

Ammonia tastes strong, and most people can detect it. Long term exposure to ammonia may appear skin pigmentation or finger ulcers and other symptoms. After inhaling a large amount of ammonia in a short period of time, tears, sore throat, hoarseness, cough, phlegm, chest tightness, dyspnea are accompanied by dizziness, headache, nausea, vomiting, and fatigue, and severe patients may have pulmonary edema and adult call. It may cause respiratory distress syndrome and respiratory irritation.

Ensure that the floor drain is filled with water

Formaldehyde complete set of equipment introduced in the past in addition to the construction of the house in addition to the water toilet design have reverse water bend, toilet and kitchen floor drain water also have reverse water bend, usually by water seal to prevent odor. In order to increase the storey height and reduce the cost, many new residential districts have cancelled the backwater bend below the floor drain, but use a new type of odour floor leak to ensure the odor of the sewer. But these floor leakage is often made of PVC material, far less than the market on the sale of stainless steel, copper ground leakage beautiful, many owners in the renovation of the replacement of the appearance of a beautiful quality of the floor leakage, resulting in the smell of toilet. Solution: the floor drain should be guaranteed to be 5 centimeters of water.

At present, the odour floor leak in the market is mainly composed of three parts: upper cover, ground leak body and floating cover. The floating cover can float up and down in the drain body when the floating cover is water. Although the floating cover can cover the sewer pipe, in order to achieve better results, the formalin complete equipment needs to operate the depth of the water seal in the floor drain, so it should be filled with water to keep the depth of the surface.
