Tarpaulin used way is different, have different performance, but generally requires: air permeability, resistance to tension, tearing resistance, anti-aging, at four o 'clock this tent factory detailed introduce for everybody below.
First we say a special analysis of property.
Three tarpaulins: in addition to the above four basic performance, also have fire prevention, mouldproof,
Five tarpaulins: it is three tarpaulins performance, but also prevent oil, dustproof performance, etc.
Note: against tarpaulins and five three tarpaulins is relative, performance can be customized according to the requirement, such as uv, nuclear, waterproof anti-corrosion characteristics of three kinds of tarpaulins is tarpaulin.
Secondly, waterproof, air permeability, tear resistance, anti-aging performance of the big four detailed parsing.
1, the permeability is tarpaulins are often used to cover the goods, so should have good air permeability, prevent the covering mildew and rot.
The permeability of tarpaulins is main factors absence made a bottom cloth, density, material, waterproof finishing agent type and amount of 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 resistance to tension is also called the tensile strength, resistance to tension, stress strength etc. , because the tent 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, resistance to tear apart also is a great judge tent quality standards, because the tarpaulin cover items not rules, which makes it to power from different angles, if can't protect damaged goods.
In addition, tarpaulins damage mainly caused by the tear, tear strength relates to whether the tarpaulin will be broken due to fly to the role of external things or for some reason after the formation of holes to expand, forming 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.
4, the anti-aging, anti-aging is the new requirement of user for tarpaulin in recent years, there would inevitably be late because tarpaulins in the use of aging, affect the use effect, if tarpaulins have anti-aging performance, can prolong service time, reduce customer costs.
In addition to the above introduction part, the different purposes, for the tent and water resistance, stability and flame retardancy requirement.
1, 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, bending or wear on the surface, coating is easy to rupture, can cause mud.
2, 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.
3, 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.
Until today in development of tarpaulins is nearly two thousand years of history, in the use and production functions more perfect, greatly enhance the performance, like cold resistance, heat resistance, tent cover, creep resistance and repeated fatigue resistance, wear resistance and resistance to bending rupture these professional tent terms, also began to be user evaluation tarpaulins reference standards of quality, and tarpaulin factory aims to provide users with more and better tarpaulin products.
Above is linyi liqun tarpaulin factory in accordance with the requirements of workshop production summed up some tarpaulins performance requirements, may be not perfect, if you have other about tarpaulins knowledge to learn, can focus on our website: http://www.
