Performance requirements and performance index of the tarpaulin you know about it?
Linyi tarpaulin factory below to share with you once: (
A)
Analysis of the basic performance requirements from all kinds of tarpaulins, general should reach requirement is: (
1)
Light weight, easy to fold and easy to operate;
(
2)
High strength, wear resistance, long service life;
(
3)
Waterproof and breathable performance is good, the side against the condensate;
(
4)
Acid and alkali resistant, mildew, corrosion resistance;
(
5)
Good weather resistance, flame retardant, fire prevention;
(
6)
Coreless absorption effect, there will be no guide wet phenomenon.
Tarpaulin class general requirements with functions of 'three prevention'.
Namely, waterproof, fire prevention,
Flame retardant)
, mouldproof.

Main performance index in the concrete product design or use, want to consider to tent the following performance indicators.
1, permeability: analysis must take into account the permeability, especially in military tent cloth, tissue permeability factors of absence made a bottom cloth, density, quantity of materials, waterproofing agent, resin adhesion, etc.
With the increase of amount of resin adhesion, tarpaulins decreased permeability.
Of course that is associated with the finishing agent used.
Most generally has the awning room ventilation for the paraffin or propylene eyes resin finishing of cotton, short whalen, QiGuan rape d fabric products.
2, tensile strength: tarpaulins when use to withstand all kinds of tension, such as fixed by tension taut, in use process should be the role of the wind, rain, and other additional force.
In spite of these forces, still require them to keep the original shape, not easy deformation, which requires the tarpaulins have higher tensile strength, latitude and longitude and should not be too big to tensile strength.
Especially as an inflatable building large tensile strength awning room is very important.
Generally the bottom cloth with high tenacity polyester, whalen isometric fabrics.
The vinyl chloride resin, sulfonyl chloride waterproofing acylation of polyethylene resin.
Products of strong mainly by the strength of the fiber and fabric density.
3, elongation and dimensional stability: as awning room and big awning room, the roof is often used under tension.
Fabric elongation shoulds not be too big, its dimensional stability is determined by the creep properties of materials.
4, tear strength: tarpaulins damage mainly caused by a tear, so the tear strength is an important index of tarpaulin.
Tear strength relates to whether the tent will be broken due to fly to the role of external things or for some reason after the formation of holes to expand, to form the structure of the large crack.
So, when the tension is big.
Requires both canopy cover with high tensile strength, it has high tear strength.
5, water resistance, water resistance is one of the important features, tarpaulins by dipping, fill the vinyl chloride tree fat in fabric clearance, form a coating.
If the amount of resin adhesion per unit area is more than a certain degree, water resistance is not a problem.
If the coating is thinner, by bending, gentle rub or wear on the surface, coating is easy to rupture, can cause mud.
6, flame retardancy, from use of the safety of mountain, requirement analysis has good flame retardancy.
Flame retardant will be selected by flame retardant fiber and flame retardant fabric.
Can also be implemented by adding flame retardant coating agent.
Flame retardant additives and flame retardant effect has a direct relationship.
Tarpaulins in addition to the above several kinds of performance requirements, it also requires has excellent cold resistance, heat resistance, canopy cover, creep resistance, repeated fatigue resistance, wear resistance and resistance to bending rupture, etc.
