Solutions to Common Faults of Secional Garage Door –II

Here are some common faults of industrial 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 3: Hand chain of the Secional Garage Door cannot move.

 Reason: The ring chain block the cross-recess, the pawl doesn’t separate from the ratchet wheel or the chain-press frame is blocked.

Solution: 1.  Put the ring chain in order;
        2.  Adjust the relative position of the pawl and chain-press frame and replace the lubrication pin roll.

Fault 4: Control failure of the Secional Garage Door

 Reason: Relay contact is stuck; travel micro-switch is invalid, wafer is deformed, holding screw of the slider is loosened, screw of backup plate is loosened and the backup plate is displaced, so the slider or nut can not move with the rotating of the lead screw. The transmission gear of the limit switch is damaged, the up or down keys of the button is blocked.

Solution: 1. Replace the relay
           2. Replace the micro-switch or wafer
           3. Replace the transmission gear of the limiter
           4. Replace the button

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
