Borosilicate Foam Glass Lining Brick - China

Borosilicate Foam Glass Lining Brick

1 - Borosilicate foam glass, B203 containing, has good resistance to both acid and alkali, so it is a good protection layer to acid condensation produced from wet desulphurization.

2 - It works as a barrier to the alteration of high temperature and low temperature inside chimney, thus relief the chimney wall from thermal stress, and extend the service life of chimney.

3 - The compression strength of B203 containing foam glass brick reaches more than 1.5MPa, which significantly exceeds the requirement of chimney liner, in a way offers potential to reduce the cost of the chimney.

4 - Its coefficient is less than 0.058 w/m.

k, and its service life is the same as the chimney itself.

• Business Description: Zhejiang Dehe Insulation Technology Corp., Ltd was founded in 1976 with the former name Jiaxing Thermal Insulation Material Factory as the first insulation enterprise being engaged in developing, manufacturing, distributing and servicing of foam glass.
  
  Prior to others of this industry a professional insulation installation company was set up in 1993, which was qualified as grade A of national installation qualification.
  
  Besides it has trained a large number of production personnel, construction personnel and technical personnel and was honoured as Whampoa military academy in thermal insulation industry.
  
  In 2012, it took the implementation of joint-stock reform and officially changed its name to Zhejiang Dehe Insulation Technology Corp., Ltd in 2015 .
  
  In addition, it invested 390 million RMB to set up Tongxiang Dehe and Jiangsu Dehe as its owned subsidiary.
  
  Now, Dehe's total registered capital reached 141.9 million RMB (among it Zhejiang Dehe is of 40 million RMB, Jiangsu Dehe is of 60 million RMB, Tongxiang Dehe is of 30 million RMB and anti-corrosion installation industry company is of 11.8 million RMB), and fixed assets is 460 million RMB.
  
  Besides it covers an area of 185 thousand square meters and production capacity of foam glass reached 400 thousand cubic meters among it the designed production capacity of ASTM foam glass is of 300, 000 cubic meters, cold pipe bracket(HDPIP) is of 50, 000 set , polyisocyanurate (PIR) and rigid polyurethane foam (PUR) is of 100, 000 cubic meters respectively, black (white) flame retardant mastic sealant is of 2, 000 tons, DH cryogenic adhesive and DH TN-1 adhesive is of 1000 tons respectively.
  
  As one of the largest enterprises manufacturing foam glass in Asia, it is also the national industry standard drafting unit of foam glass.
  
  The foam glass of Dehe has been included National Torch Plan Industrialization Demonstration Project and Dehe was titled of high-tech enterprises in Zhejiang.
  
  Firmly cling to the idea that morality first, harmony forever Dehe was committed to offering perfect solutions for insulation and strive to pursue NO.
  
  1 in China and even being NO.
  
  1 around the whole world.
  
  Chairman Chen Mingde with the staff sincerely welcome your visit and guidance!
