A frequent question from customers : What's difference between mgo board and fiber cement board? I couldn't found any correct answer on intertet,here my thinking for share. Mgo board belongs to cement bonded wood particle board(CBPB) existed over hundred years, MGO BOARD use innovative binder - magnesium oxide cement, boned with wood particle and reinforced by mesh fiber on both side,rolling into a flat sheet. The main advantage of MGO is light weight,exllect fireproof, high bending and impact strength,superior screw holding strength. The main disadvantage is deformation(bulging) in heat and wet environment, because of nonuniform wood particle mix inside. Fiber [...]
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 [...]
Views:7619 Author:Rockmax Publish Time: 2018-12-13 Mgo Board Problem Mgo board is a innovative fireproofing building materials, it is popular for superior fire resistant, low heat transfer, high strength and economical efficiency. Now BBA, LABC, CCMC, CERT MARK, University of Denmark and St. Petersburg warned some of mgo board contains chloride which has risk of corrosion to steel frame and damp insulation materials in humidity environment, damage adjoining building components. ROCKMAX has been work in MGO industry over 11 years, would like to share our experience about mgo board. What is mgo board? Magnesium oxide board or "mgo board" [...]
Views:619 Author:Rockmax Publish Time: 2016-12-13 Today mgo board plays an important role in fireproof building materials industry. Because fireproof,impact and flexibility performance of mgo board is better than fiber cement board and gypsum board, moisture,termite and mildew resistant is better than wood panel. In recently,we found many negative informations regarding mgo board for external applications, it may involved panel deformation(bulging) or cracking at joint. Internet has misrepresented MGO BOARD's perforamance, mislead end user use MGO replace of fiber cement board for cladding use, when builder install and treat it in the same way as fiber cement which [...]
