Formaldehyde's three most feared earth methods white vinegar

The three earth methods that formaldehyde is most afraid of are white vinegar with water, white vinegar with salt, and white vinegar with pineapple.

1, white vinegar and water

White vinegar and water deformaldehyde method is relatively simple and economical and practical, just need to mix white vinegar and water according to a certain proportion. Generally speaking, you can use 2 parts of water to adjust 10 parts of white vinegar, after mixing the white vinegar water will be sent in the corner of the room, every 500ml for a calculation unit, every 15~20 square meters can be placed in a unit, you can moderately adjust the concentration of vinegar and water and the placement of the position, you can effectively reduce the content of formaldehyde.

2, white vinegar and salt

White vinegar and salt method of formaldehyde in many families is also relatively common, only need to add a small amount of salt in the white vinegar, mixed evenly in the room can be placed, the same every 15-20 square meters can be placed in a unit, you can also adjust the concentration of vinegar and water and the location of the position, this method for the indoor has a bad smell or formaldehyde situation very effective.

3, white vinegar and pineapple

White vinegar and pineapple deformaldehyde method is relatively more environmentally friendly, in fact, the chemical reaction of white vinegar and pineapple can really reduce the content of formaldehyde. To use this deformaldehyde method you need to prepare some pineapple and about 1000ml of white vinegar, put the pineapple in a small bowl, pour in the right amount of white vinegar, wait for about 24 hours, and then sieve out the vinegar water, you can cool it down and pour it into a spray bottle, and spray the room.

Industrial use of formaldehyde

1, synthetic resins

The biggest use of formaldehyde is used in the manufacture of urea-formaldehyde resin, phenol-formaldehyde resins and honey amine formaldehyde resins, which are widely and in large quantities used in the timber processing industry, the home and building decoration industry, the furniture industry, etc., and used as a secondary auxiliary for the processing of paper, textiles, leather, Concrete plasticizer, molding materials, casting materials, insulating materials, flame retardant coatings and flocculants for sewage treatment. Amino resins are also used in the manufacture of molding materials, for amino plastic products, electrical materials, construction materials, tableware substitute materials.

2, the synthesis of polyols

Formaldehyde is an important raw material for the synthesis of polyols, widely used in the production of pentaerythritol (dipentaerythritol), trimethylolpropane, trimethylolpropane, neopentyl glycol, dipentaerythritol, dihydroxymethylpropionic acid, and acetylenic aldehyde method of 1,4-butanediol and so on.

3, synthetic fibers and dyeing and finishing additives

The earliest synthetic fibers vinylon fiber is produced with formaldehyde as raw material, mainly used for low-grade clothing, industrial packaging materials and tire cord. There is still some production and application in China, North Korea and Japan.
