Solutions to Common Faults of Sectional Garage Doors –I

Here are some common faults of sectional garage doors you might meet in its operation. We give some solutions to them for you. Hope it will help you one day if the professional man are not around.


Fault 1: The electric motor of sectional garage doors is not work
Reason: Line short, motor is burn out, “stop” button is not reset, load is too large.
Solution: 1. Check the circuit and connect the burn out motor;
        2. Replace the button or repeatedly press the button;
        3. Push the slider of limit switch away from the micro-switch contactor and adjust the position of the micro-switch;
4. Check whether there is jamming in the mechanical part or not. If there is, eliminate the jamming and cleaning up obstacles.

Fault 2: The vibration or the noise of the sectional garage doors is too large.
Reason:  The brake disc is imbalanced, cracked or not fastened; Oil loss of bearing; Gears is not messed well, damaged or short of oil; Current sound or vibration of the motor.
Solution: 1. Fasten the nut of brake disc;
2. Replace the brake disc or re-adjust its balance;
3. Replace the end gear or lubrication oil of the electric motor;
4. Replace the bearing;

What’s the difference between PIR and PUR?

Both PUR and PIR are a kind of rigid PU. However, they have different physical properties and chemical properties. I . Difference between the raw material Rigid PU consists of polyol and isocyanate. Polyol can be divided into polyether glycol and polyester polyol. Reaction between polyether glycol and will generate polyurethane foam(PUR); Reaction between polyester polyol and isocyanate will generate polyisocyanurate foam(PIR). II. Properties of PIR PIR  is a kind of deep cold heat insulating material, which can be applied at the temperature from -196°C to 120°C. It has the advantages of thermo-stability. The index of black material of PIR is much higher than PUR, of which PIR is 110-120; PUR is 250. Only when the index of black material is over 200, it can be called PIR; if it is under 200, it can only called the mixture of PIR and PUR. Generally speaking, the white material of PUR is made of polyether; that of PIR is made of polyester. PIR has good thermo-stability, inflaming

What’s the advantages of Wall Cladding System for Decoration and Insulation?

1. Insulation Performance  Insulation performance of the wall cladding system depends on the raw materials of the insulation layer. Generally speaking, the insulation performance of organic insulation materials(such as EPS, XPS, PU and phenolic resin foam) is better than the inorganic materials( such as rock wool, glass wool, perlite and foam cement). 2. Fire-protection rating  As the decorative insulated wall cladding system covering the whole buildings, if its raw material is not fireproof, fire will be easy to spread through the building and bring serious dangerous to people. So we need to choose the wall cladding system with higher fireproof performance. The fire-protection rating of the wall cladding system depends on the flammability of the insulation material. There are two main fire-protection ratings, namely, Grade A and Grade B. Grade A refers the highest fire-protection rating. Insulation material of Grade A: Rock wool panel, foamed ceramic panel, foam cement pa
