Help you understand the quality requirements of formaldehyde emission from plywood

Suggested collection! Help you understand the quality requirements of formaldehyde emission from plywood for home decoration!

I have been engaged in plywood export trade for 16 years, and have experienced the transformation and development of China’s four major plywood production bases. Each plywood producing area has its own unique advantages, some of which have good prices, some of which are stable in quality, some of which have a wide range of specifications, some of which require high formaldehyde, and your output is large.

A long time ago, there was a saying in the industry that first-class quality plywood was exported to the United States, second-class quality plywood was sold to China, and third-class plywood was exported to Europe and Middle East Africa. It was a real phenomenon before 2008. At that time, every factory was proud to make American goods because of the high quality requirements of the United States.

Where is the high level? The basic characteristics of the products require little change, and the formaldehyde emission requirements which require the greatest change. Because some individual politicians in the United States believe that formaldehyde emission from China is difficult to meet the barriers designed by the United States. First, the requirements of CARB P1 phase were put forward in about 2009. 1. Carb certification P1: Phase 1 (P1) began on January 1, 2009, and requires the use of climate box method ASTM E 1333 or ASTM D 6007 to test formaldehyde emission from board.

Carb P1:

Formaldehyde release from density plate < 0.21ppm/M3

Formaldehyde emission from Particleboard < 0.18ppm/M3

Formaldehyde emission from plywood < 0.08ppm/M3

Around 2010, most of China’s plywood factories have fully met the certification and testing requirements of CARB P1. Of course, some cheating factories add formaldehyde traps to reduce formaldehyde emissions.

Carb Certification P2: Starting from 2010, the requirements of the second phase (P2) of the regulations will be implemented one after another. Starting in 2001, the United States began to require all plywood entering the United States to meet the requirements of CARB P2, which is the requirement for all plywood entering the United States. Basically, in about a year, most factories in China that are in the U.S. market have met the real requirements of CARB P2 testing.

Carb P2:

Formaldehyde release from density plate < 0.11ppm/M3

Formaldehyde emission from Particleboard < 0.09ppm/M3

Formaldehyde emission from plywood < 0.05ppm/M3

According to the instructions of American customers, ppm is the unit of concentration. For water, the density is 1g/cm_and the conversion unit is basically 1ppm=1mg/kg=1mg/L. Carb P2 is more environmentally friendly than carb p1. Combining the above comparative data and comparing the formaldehyde emission of wood-based panels, we can select and customize the cabinet and wardrobe panels very well.

Generally speaking, Carb P2 is superior to E0 and carb P2 in environmental protection grade, so overall, carb P2 is superior to national standard E0, CARB P1 is superior to E1, and national standard E0 is superior to national standard E1.

Classification standard of E+digital O12 commonly used in China:

E0 (formaldehyde emission less than 0.5 mg/L)

Grade E1 (formaldehyde emission 0.5mg-1.5mg/L)

E2 (formaldehyde emission greater than 1.5mg/L)

Now according to the requirements of the state, all indoor panels must reach the level of E1 and E0. This requirement has also been raised a lot, which is in line with international standards or even higher than international standards. Of course, there are also some manufacturers can not reach, are the need for consumers to open their eyes to distinguish.

Therefore, when using or purchasing wood-based panels, suppliers or retailers can be asked to provide a formaldehyde detection report to see what their formaldehyde detection value is. See clearly whether the testing party is a manufacturer or a third-party testing agency, to prevent cheating, after all, formaldehyde affects the health of users. At the same time, suppliers are required to sign quality assurance agreements in black and white, especially formaldehyde emission requirements.
