The mgo board with full certificate,recommend for such exterior applications: a-The render system has insulation material laminated on outsite,great performance. b-Underlayment for exterior decoration,such as tile,marble, aluminium composite panel,curtain wall,good performance.. c-In direct paint system,try to decrease moisture exchange as less as possible,good performance. d-replace MDF or Gypsum board in exterior system,save a layer of water barrier,meanwhile increase waterproof and fireproof. e-other exterior application,need to consult with mgo factory and paint factory

ROCKMAX MAGNESIUM CEMETN BOARD  is one of the leading MGSO panel in China,it is chlorie free, climate resistant. we have passed climate resistant test in Stuttgart,Germany and full durability test has been done in SGS Shanghai, durablity test  to EN ISO 12467 -2012, Grade A class 3. Conclusion is After the completion of 50 heat-rain cycles the wall was inspected for damage. The complete wall surface exhibited no cracks, delamination, deformation or bending, see Figure 2, Enclosure 2. One of the boards exhibited slight lime efflorescence, as shown in Figure 2, Enclosure 2. Based on these results it can [...]

In order to rebuild market confidence,ROCKMAX suggest 1,Distributor need to have a deep understanding the technical level of your mgo factory make sure of what level of mgo you are selling,and what kind of application is going to use. because mgo board has different type and different quality level. Basiclly has 3 type,  -magnesium oxychloride hydrate  -magnesium oxysulfate hydrate  -magnesium oxyphosphate hydrate The difference is they are fomulated with different kind of salt. Different quality level mgo should put in appropriate place. 2,The designer,should understand exterior wall panel need strength remain above 0.75 and low water absorption rate,There is no exception for [...]

Today mgo board plays an important role in fireproof building materials industry.The reason is:Mgo has better fireproof than fiber cement board and gypsum board at same thickness,meanwhile its heat transfer is less than half,bending strength and flexibility even better. Mgo is termite resistant and mildew proof,better than wood,and price is similiar.In recently,we found more and more negative informations about mgo board for external wall it may involved panel bending or cracking at joint,decoration material such as tile,marble fall off.People is afraid and want to make sure of mgo board for exterior use? Most of producers would say their mgo board can [...]

RockMax mgo board  is a superior green building materials. It is made from recycled plant fiber and natural mineral. The production process is almost carbon-neutral. As well as being easy on the environment, our products contain 0% toxins and are completely safe for both builder and end user. 1,RockMax magnesium oxide board is a magnesium oxide cement product. Magnesium is one of the most common element in the earth, it is widely use in medical and food industry. Made from recycled oil palm fiber or wood fiber RockMax board contains 100% recycled or recovered fiber. All the fiber we use originates from post-industrial recycled agricultural [...]

1,ROCKMAX is new generation chloride free mgo board, do not have corrosion problem. 2,ROCKMAX is approved panel,test in full 3,ROCKMAX's material safety meet European "REACH",exclude 191 kinds of harmful material may effect health. 4,ROCKMAX provide guarrantee for steel frame system safty,compensate 200% on CNF price ,when chloride>0.5%.

Chinese magnesium oxide board industry association issued new industry standard for export mgo board,on June 11th,2018 all the export chloride mgo board require to state limitation in export document and specification. 1,Chloride mgo board is limited to indoor and other non humid condition, unless make appropriate waterproof treatment. 2,Chloride mgo board shall not be directly contacted with metal parts without rust treatment

4 options 1-Use stainess screw and stainless frame or aluminmium frame. 2-Replace steel frame by wood frame and stainless screw 3-Laminate a plastic film on reverse that next to the steel frame 4-Dismantle magnesium chlrodie board,use chloride free mgo board instead

2 options 1-Pour a cup of purified water,immerse some fine screw and mgo board sample.Check corrosion after 7 days. 2-Contact local testing lab,such as SGS. chloride content inspection,cost $300-400. It takes 7 working days
