At present, most of the indoor optical cables use tight-fitting optical fibers or single-core cables as the basic units. Aramid yarns are reinforced and soft optical cables with flame-retardant or non-flammable jackets are used. Its advantage lies in that the tight sleeve is integrated with the optical fiber to provide good mechanical protection, so that the optical fiber exhibits good compression and bending resistance when terminated, good flexibility and toughness, and a small bending radius; Good environmental protection, improve the service life of the optical fiber.
The tight-fit optical fiber also provides excellent moisture protection; the tight buffer layer is easily stripped to the fiber core; compatible with all standard connector types; simplifies termination procedures and reduces termination costs. The tight fiber optic design and the flame retardant or non-flammable jacket make the indoor fiber optic cable fully meet the requirements of indoor safety applications. Therefore, the indoor high-performance communication transmission applications generally use indoor fiber optic cables tightly designed.
In the integrated wiring, we generally use two kinds of optical cables: vertical lifting cable and ratproof cable. Vertically lifting optical cable is to connect the entrance equipment, equipment room or computer room with communication cabinets on different floors after the optical cable enters the building, which is called “vertical wiring systemâ€. At this time, the optical cable is mostly located in the vertical pipeline of the shaft between the floors. For this purpose, the optical cable needs to withstand greater tensile force; rat-proof cable: single-core or multi-core tight-clamped optical fiber cable protected by stainless steel hose, which has strong lateral pressure resistance, bending resistance, tensile strength High, excellent anti-rat performance. It can be used for occasions where trampling takes place, for example, laying under carpets or limited space where frequent bending or rodent damage is required.
As a transmission medium for integrated wiring system engineering, optical fiber cables have a wider range of applications and continue to meet people's needs for information and communication networks. Since the environment in the room should be quite special, while indoor fiber optic cables maintain very good flame retardancy, mechanical properties, and light transmission characteristics, they must also meet the requirements for toxicity, corrosion, and low smoke in the standards. So how to meet the indoor optical cabling cable demand?
External wall insulation decorative integration board is the external wall insulation system and exterior decoration system combined into one. It can effectively improve the user's return on investment, improve project quality. Reduce energy consumption, greatly shorten the external wall insulation and decoration project duration.
insulation Wall board decorative by the insulation layer, inorganic resin board, strong composite plastic, decorative coating composition, fire rating in full compliance with national fire inspection and acceptance standards.
External wall Insulation Decorative Board scope of application
Whether in the cold of the north, or the hot south, thermal insulation decorative panels integration effect can meet the national mandatory energy-saving regulations. The selected materials with high weather resistance, able to resist acid rain, salt spray erosion.

Three external insulation system briefing
First, EPS board insulation coating finishes system
introduction:
EPS board thin plaster Exterior Insulation Board system is composed of dry powder, insulation board, alkali-proof fiberglass mesh cloth and finishes layer wall insulation and decorative features in one of the new wall insulation structure system, EPS board Thin plaster insulation system is the most common at home and abroad, the most technologically mature external insulation system. The system uses EPS board paste exterior insulation, with the overall insulation effect, thermal conductivity is small, does not destroy the insulation layer, cut off the hot and cold bridges, there is no condensation point, good durability and so on.
Application:
The system is suitable for the construction of new building exterior wall thermal insulation finishing projects with concrete walls, lightweight filling masonry, clay bricks and other materials as well as energy-saving renovation of existing buildings.
Second, XPS board insulation coating finishes system
introduction:
XPS board insulation wall panel system is composed of dry powder, interface agent, insulation board, alkali-proof fiberglass mesh cloth and finishes layer wall insulation and decorative features in one of the new wall insulation structure system, XPS board Exterior insulation has the overall effect of thermal insulation, thermal conductivity is small, cut off the generation of hot and cold bridges, there is no condensation point, good durability and so on. At the same time, the light weight of such systems can effectively reduce the load on the load-bearing walls outside the building and the foundation load, reducing the basic handling costs of seismic fortification. Such systems can be vigorously promoted and popularized building energy-saving insulation system.
Application:
The system is suitable for the construction of new building exterior wall thermal insulation finishing projects with concrete walls, lightweight filling masonry, clay bricks and other materials as well as energy-saving renovation of existing buildings.
Third, plastic powder polystyrene insulation coating system
introduction:
Adhesive polystyrene particles insulation coating veneer system is composed of premixed dry-mixed mortar as the main binder, adding appropriate anti-cracking fibers and a variety of additives to polystyrene foam particles as lightweight aggregate, the proportion of configuration, The use of on-site molding plastering process, the material is easy and easy to operate, the construction efficiency is high, the overall performance of the material after molding is good. Avoid block material insulation, easy to crack joints, the construction process is simple. The system insulation layer and the main wall of the close bonding between, no cavity, hollowing phenomenon, effectively solve the wall insulation, heat insulation, crack resistance, fire resistance, water repellency, weather resistance, ventilation and other issues.
Application:
The system is suitable for the construction of new building insulation wall panels external finishing projects with concrete walls, lightweight filling masonry, clay bricks and other materials as well as energy-saving renovation of existing buildings.
