According to the geothermal cardin performance to identify the quality of the products

how to identify the quality of the plastic card pin? Basically see the following several aspects of plastic nail performance:

1, hardness, card nail tip can smoothly into the aluminum foil paper and polystyrene.

2, toughness, card into the insulation layer after two pairs of teeth quickly open, in order to achieve maximum tension.

3, low temperature resistance, card pin should be 10 degrees Celsius below zero any folding, roll, twist, impact, can't fracture pressure, maintain the stability of the fixed performance.

4, inverted tooth Angle of mechanics is reasonable, if a man empties his tooth is too short, Enter the eps board did not change) , too hard, On the insulation layer) tied the two pit Too much, or inverted tooth spacing ( Cause at the time of hard tooth roll) It would thermal insulation layer, increased the staple usage, reduced the construction efficiency, unit costs rise.

at present most of the floor heating pipe installation is to use plastic nail fixed tube, geothermal card pin is divided into: a pair of tooth, two pairs of teeth, three pairs of teeth, and go down the steel nail using several types. Geothermal card pin factory mainly produces insulation nails, nail geothermal CARDS, nylon rods, etc.

'two pairs of teeth' the use of geothermal staple the most obvious advantages, its mechanics Angle of tooth design the most reasonable, most upside down force. So, in the domestic and foreign professional floor heating construction units in the use of two pairs of teeth plastic nail.

'a' and 'three pairs of tooth' geothermal card pin for resistance to take off the drawing force and pulling force is too small, has now virtually eliminated by construction unit. While 'CARDS used with steel nail nails' is mainly used in the foamed cement as a thermal insulation layer of floor heating engineering.

'two pairs of teeth' plastic nail

plastic card can nail and points for manual and mechanical with two kinds:

by hand by hand directly with refers to the construction personnel nailed card inserted into the insulation layer, the usage of card pin considering construction personnel feel comfort, in order to improve construction efficiency.

machinery mainly refers to the card nail gun, construction with a nail gun, can greatly reduce the labor intensity of workers, skilled card nailed the gunners construction can almost reach jogging speed; Card nail gun and most strict with plastic nail, size to be completely consistent, there cannot be an incomplete, because every plastic nail quality affect the use effect of staple gun.

geothermal card nailed manufacturers talk about geothermal card problems:

tube 1 square meter of floor heating need how many geothermal card pin?

laying pipe per square meter of floor heating is to use card to the dosage of the nail has the following several factors:

1. Pipe material: PB pipe and PE RT tube pipe some relatively soft, use less than PE - X-ray tube;

2。 Insulation material: thermal insulation layer is the basis of nail fixed card, within a certain range, General floor heating insulation board density is not higher than 40 kg per cubic meter) The higher the foundation strength, the less they use qualified card pin number. For example: use the bulk density of polystyrene under 17 kilograms per cubic meter, it is a good card nail fixed because there is no solid foundation, use also increased substantially.

3。 Tubing length: because of the differences in temperature in different regions, the design of the heat load is different, use different pipe length. In northeastern China, for example: usually a square meter floor heating pipe laid more than 5 meters; In Shanghai laid about 3 meters can meet the heat load requirements.

4。 Geothermal staple quality: according to the law of conservation of energy, within the same thermal insulation layer and the length of pipe material, need fixed force is the same! Geothermal staple quality, the higher the less usage, the poor quality of geothermal staple as the low fixed force will need to increase the usage.

geothermal card pin?

how, basically see the indoor heat preservation do if indoor heat preservation heat preservation and substrate well, heating effect of each is the same.

how long a nail geothermal card?

straight pipe pipe clamp distance between 0. 5 - 0. Seven meters, bending section pipe clamp distance between 0. 2 - 0. 3 meters.

floor heating pipe fixed way mainly adopts geothermal card nailed to a fixed, the use of the card pin to make floor heating pipe fixed more rapid and convenient. Steel stud card are U design, u-shaped opening distance according to the diameter of the floor heating pipe to determine, is commonly 3. 5 - 4. 0 cm, slightly bigger than the staple of semicircle diameter, this design is mainly use the elasticity of the nail wire card itself, make card pin has a stretch of outward.
