1.About EPS Cement Sandwich Panel
1).ZJT EPS Sandwich Panel
ZJT Light Composite Energy-saving Sandwich Wall Panel is composed of face panel and interior filling. The material of face panel is thin fiber cement board or calcium silicate board,and the middle is filled with lightweight composite core material,including cement,EPS and fly ash. The quality and technology of product have reached to a new level and become the leading brand among the similar products.
The product has solid,lightweight,thin,better strength,impact resistance,hanging strength,heat insulation,sound insulation,fireproof,waterproof,easy cutting,pet and rot resistant,increasing usable space. It can be arbitrary slot,without batch file,dry operation,enviroment protection,which achieve energy conservation and energy efficiency. At the same time,this reduces the total area to be occupied by the wall and to raise residential practical area,alleviates the structure load,improves the building aseismatic capacity and safety performance,and reduce total cost. This production technology and application is the reform of our country wall material,is a new breakthrough.
The company relying on advanced equipment,first-class technology,excellent quality,strong,productivity,favorable customer service system,has set up the good brand image in the market,and been widely recognized by the same.
2).Product Composition

| Features | More Detail | ||||||||||||
| 1 | green | 100% free of harmful substances and are of A non-radioactive products, 100% Non-asbestos. | |||||||||||
| 2 | lightweight economic | The volume-weight only 750-800kg/m3 , the weight of 75mm thickness ZJT board is 54kg/m2, equal to 1/6 of brick weight, 1/7 of 120mm thickness masonry. | |||||||||||
| 3 | increase valid space | the thickness of ZJT wall decreases 85mm by using 75mm thickness ZJT boards. Thus, valid space increases 1/m2 per 11.8mm. in other words, it can increase 6/m2 per 100/m2 . | |||||||||||
| 4 | moistureproof waterproof | will keep dry and leave no stains. During humid days, the boards will not condense water either. suitable to be installed in such wet areas as kitchens, bath rooms, basements because of its moistureproof and waterproof. | |||||||||||
| 5 | fireproof | Fireproof limit of ZJT boards is more than 4 hours and does not emit toxic gases under 1000 degree. The nonflammable performance reaches national A-class standard. | |||||||||||
| 6 | heat insulation | ZJT board is composed of special material to keep heat and thermal within a favorable condition. At same time, the ZJT boards are able to adjust moisture automatically and keep moisture at a balance level. | |||||||||||
| 7 | sound insulation | The raw materials of ZJT boards have good performance in sound insulation. ZJT board with 90mm thickness gains sound insulation of 42dB. | |||||||||||
| 8 | walls can be nailed and grooved | ZJT board can be grooved to have conductor arrangement or nailed to hang heavy object. The surface of ZJT board is smooth enough to make finisher processing directly with tile, wall trim and so on. | |||||||||||
| 9 | good integration | By using steels at the joints, the strength of walls is high enough to do partition in large story height and long span structures and it anti-seismic performance is several times higher than masonry. | |||||||||||
| 10 | easy and fast construction | It can be cut to adjust length and width at will. The process of installation is easy and fast, without the need of pl | |||||||||||

Installation of Sandwich Building Panel
Alignment:making the base line of the installation position of the wallboard.
↓
Sawing of wallboard:cutting and adjusting the width and length of wallboard on the basis of the requirement.
↓
Sizing: blending the ZJT cement mortar and plastering it into the gap and base line bettwen the wallboard.
↓
Fitting the sheet: moving the mortar-covered wallboard to the right position and using crowbar to ensure the wallboard are tight with another one.
↓
Placing the wallboard: filling the vacant position of the wall
↓
Adjustment: fixing the wallboard with wooden wedge, spiking steel bar into the glued wallboard an two steel bars should be spiked beyong 120mm wall board.
↓
Filling joints: clear away the facial panel cement mortar and press it tightly with round steel bar.
↓
Installation of crack-resistant material: after about one week, taking out the wooden wedges.
↓
Insertion of wires: do not dig the same place in the two wallboard facial and the deep can't beyond 2/3 of the wallboard.
↓
Platering paint: to finish the wal, tiles can be taste without any scraping and wallpaper also can be applied directly.
