According to the home special issue and the home business association, the air quality test was carried out on the children's room of 20 families. The results showed that the formaldehyde exceeded the standard rate of more than 80%, including 30% of benzene series and 45% of total volatile organic compounds (TVOC). Source eight became children's furniture. During the inspection process, it was found that the decoration of multiple households was not complicated, but the formaldehyde content of formaldehyde, stupid, xylene and TVOC in each house was detected, and the formaldehyde content exceeded the standard. Among them, the parents' bedroom is only slightly exceeded, while the children's room formaldehyde and TVOC are seriously exceeded. It is understood that these family situations are quite similar, both are the old furniture used in the parents' room, but the children's room has purchased brand new children's furniture, and most of them are plate-type and colorful furniture. According to the Secretary General of the Chamber of Commerce, the main source of pollution in children's houses is reflected in children's furniture. The crux is mainly plate furniture and surface paint. Parents need to pay attention to the fact that formaldehyde, benzene and other low standards will also affect the health of children, especially children under 5 years old. "Formaldehyde release pollution is the main cause of increased asthma in children under 5 years of age. Long-term exposure to low doses of formaldehyde can cause chronic respiratory diseases and eye diseases. If it is a pregnant mother, it may lead to pregnancy syndrome, neonatal malformations. , mental depression and other diseases." Experts analyze that the current market for plate-type children's furniture is mostly medium-density board and particle board, only some well-known children's furniture brands use pine and other laminated materials. “Because the use of adhesives in MDF and particleboard is very large, the health problems of formaldehyde and other harmful substances in children's furniture are more serious than other furniture.” Zhao Chunyan, general manager of Andes, reminded consumers that she is working in the long-term inspection. It has been found that the brighter the color of the paint, the more heavy metals it contains, such as lead, which is mainly caused by the lead compounds contained in the paint.

Hastelloy is a nickel-base alloy that was originally developed as a container material for molten fluoride salts, to which it has good resistance in the temperature range 1300 to 1600ºF (705 to 870ºC).

The alloy has good oxidation resistance in air, and may be used to 1800ºF (980ºC) or intermittently to 1900ºF (1040ºC)
