Why is formaldehyde in the curtain? This is because in textile production, in order to improve the wrinkle resistance of the fabric, improve the waterproof performance, pressure resistance, color fastness, fire resistance, etc. of the textile, etc. Auxiliary. In the process of textile printing and finishing (soft finishing, stiffness finishing, anti-crease finishing, etc.), various dyes, auxiliaries, and finishing agents are added, and the resin contained therein contains formaldehyde. These formaldehyde-containing resins will remain after finishing and will release formaldehyde. In general, textiles with finishes and coatings have a higher formaldehyde content. When the textile is exposed to the air for a long time, due to the volatility of formaldehyde, it will be continuously released and pollute the indoor environment. In particular, some residential windows nowadays are relatively large, such as floor-to-ceiling windows, viewing windows, and a house with a decoration of about 100 square meters. It costs 800,000 yuan to buy curtain fabrics. This is why some families pay special attention to controlling formaldehyde when decorating their homes. Pollution, but after testing after renovation, one of the reasons for excessive formaldehyde in the room will still be found.
Then, when doing interior decoration, how can I buy formaldehyde curtains to prevent formaldehyde?
First, pay attention to when buying curtain fabrics:
1. smell odor. If the product emits a pungent odor, there may be formaldehyde residue, it is best not to buy.
2. Pick the color. When choosing a color, it is advisable to purchase a light color, so that the risk of formaldehyde and dyeing fastness is lower.
3. Look at the variety. Care should also be taken when purchasing fabrics and curtains that have been retracted, wrinkle-resistant, soft, and flat.
Second, pay attention to when using:
1. The curtains purchased should be thoroughly soaked and washed in clean water to reduce the formaldehyde content remaining on the fabric.
2. In addition to curtains, some sheets, quilts and other textiles that directly contact the skin also contain formaldehyde, which must be washed after use.
3. After washing, it is best to dry the curtains in an outdoor ventilated place and then use them.
Automotive air conditioning refrigerant is also called refrigerant refrigerant car car,
commonly known as snow, ice, divided into environmental protection (134a) and non environmental (R12 few models use). The general need to fill the car refrigerant in the summer comes, the car of refrigerant should pay attention to the following two questions: one is the refrigerant not interchangeable the problem, another is the vacuum problem. Automotive air conditioning refrigerant mainly has two kinds, one is R12, another is 134a (HFC 134a R12), a long history and widespread use, but the gas containing chlorine molecules will destroy the ozone layer in the atmosphere and cause the greenhouse effect, so the number of years ago, delegates from around the world gathered in Montreal signed the protocol required in recent years to stop the production and use of CFCs products, of which R12.134a is bear the brunt of 90s began to use varieties, because no chlorine molecules without damage to the ozone layer of Car air-conditioning system changes less, and now a lot of new domestic and foreign air-conditioning systems are using 134a refrigerant
