Mgo board is well know as fire rated building board, it has been widely use for fireproof partition, structural sheathing and subfloor.  however many buyers can not evaluate quality without certification. Because there are various performance due to raw materials degree and formula composition. Do you know price differece? Mgo powder 85% activity $180/ton 80% activity $140/ton Mgso4 food degree $172/ton industrial degree $110/ton Glass mesh fiber(120g) Grade E $0.2/meter Glued Grade E $0.3/meter Plant fiber wood fiber $ 205/ton bamboo fiber $260/ton man-made fiber glass chops $1050/ton PP fiber $1200/ton Basalt fiber $2050/ton Aggregate Light perlite $25/M3 Heavy perlite [...]

Choosing right quality mgo sip for fire passive house Mgo sip are composite of 2 layers magnesium oxide cement sheathing on both side, EPS/XPS as core. Premium mgo sip intergrated fireproof, insert proof, moisture proof, mold proof, sound insulation and high structural strength. Do pay attention to following points before purchase: 1, check chloride volume of mgo board. it is relative to steel frame structural safety Some of mgo board contains high volume of chloride >5%, should not use for steel frame system 2,check impact and load bearing test report, relative to structural performance most of chinese mgo board are [...]

What is eps mgo board? Rockmax eps mgo board is similar to Permabase and Dura backer board, design for moistureproof substrate.but made of magnesium oxysulfate cement and eps. It is lighter weight,fireproof,moisture,easily cut and screw faster.Our eps mgo board has superior impact resistant. 1.20 years non corrosive warranty 2,safe material tested to EN reach 3.Waterproof coating surface 4. Durability tested to EN 12467 https://youtu.be/PlF7ix9m9nI

Today, we'd like to discuss the problem of magnesium oxide board joint crack. What is mgo board? A cost effective fire rated inorganic binded reinforced by glass mesh and plant fiber, roll into a flat sheet,that can be use for strucutal and non stuctural wall and subfloor. Why mgo board joint crack more requently? Moisture content Gypsum board and fiber cement board have mature drying facility, moisture may 10-12% when export.However many mgo board supplier don't have moisture control facility,result in uneven and excessive moisture when export,moisture may 10-25%. Dry shrinkage The dimension change of gypsum board and fiber cement [...]

"What's difference between mgo board and fiber cement board?" A frequent question asked by many customers. Before say something, we should think about which product category does mgo board exactly belongs to? In my point of view, mgo board belongs to CBPB - cement bonded wood particle board which has been listed in building materials category in both Europe and America. mgo board made some upgrates: 1,mgo board use magnesium oxide cement as binder,it has lighter weight and better fireproof than portland cement. 2,mgo board composite multi-layers of glass mesh fiber, impact resistant and flexibility increased. 3,mgo board is entirely [...]

MAGNESIUM SULFATE BOARD Magnesium sulfate board is new technical chloride free mgo board, with exceptional fireproof, flexibility and workability which is competitive product for exterior substrate, structural sheathing, sub flooring, fireproof decorative wall base board and fireproof laminated flooring base board. Each application has corresponding standard of physical and durability performance. For cladding and render system recommend to use high density fiber cement board.

Someone said “Mgo board is the wrost building material in decades” There are couple of reasons: 1,Chloride mgo board it's corrosive and damp wall 2,User treat mgo as fiber cement board,use it as cladding and render without durability test and system evaluation 3,Low strength mgo board use as shear wall   is it ending of mgo board? Due to hundreds of scientists' efforts,magnesium sulfate board get rid of chloride ion entirely. Those Germany,Italian,Canadian,Chinese scientists carry on researching magnesium sulfate cement for 5 reasons 1, Magnesium sulfate board is cost competitive for interior and exterior substrate, fireproof and moisture resistant 2, High bending [...]

We are living in the century,have to fight against global climate warming for next generation. As we all know about,portland cement production creat huge Co2. Caco3 = Cao + Co2 1 ton portland cement consume 80-110 kilowatt ,coal-fire powder creat 0.86 KG Co2. Decomposition of 1 ton limestone,creat 0.5 ton Co2 Now human produce a least 2 billion ton of portland cement every year.According to statistic,7.9℅ of global carbon dioxide emission from portland cement production. Magnesium is one of the most common element in the earth,it is widely use in medical and food industry. Magnesium oxide can react with water and Co2,reduce Co2. The production process is almostcarbon-neutral.As well as being easy on the environment, our products contain 0%, toxins and are completely safe for both builder and end user. Rockmax magnesium oxide board is made fromrecycled plant fiber and natural mineral. Made from recycled oil palm fiber or woodfiber RockMax board contains 100% recycled or recovered fiber. All the fiber we use originates frompost-industrial recycled agricultural waste No toxic ingredients [...]

Novermber 12th,2017 Magnesium oxide cement association annual meet held at Rugao city,celebrate its 25th anniversary.   The members present at meeting including :vice major of Rugao city,chairman of Chinese magnesium oxide cement association,Chinese magnesium cement Institute,Shandong Research Institute of Building Science, Resentitive from ASTM(American Society for Testing and Materials),Magnesium oxide cement association from North America-MOCA. The purpose of the meeting is work on uniform product standard and test standard of magnesium oxide cement product for demestic and international market. Chinese goverment issue new standard requirement of chloride free mgo board. From here,Chloride free mgo board represent for future of fire [...]

There is research report from Demark university. The "magnesium oxide board" mention in this report,which is mgo board contains chloride. MAGNESIUM-OXIDE BOARDS CAUSE MOISTURE DAMAGE INSIDE FACADES IN NEW DANISH BUILDINGS Kurt Kielsgaard Hansen (1), Tommy Bunch-Nielsen (2), Bent Grelk (1), Carsten Rode (1) (1) Technical University of Denmark, Lyngby, Denmark (2) Bunch Building Physics ApS, Vedbæk, Denmark Abstract Magnesium oxide board, “MgO-board”, is a factory-made sheathing board product, which has been widely used in the last 5 years in ventilated facades on new or renovated buildings in Denmark. In winter 2014/15, a number of problems began to appear with [...]
