Tent material selection and considerations1

A tent is an important piece of equipment for camping, but not a piece of equipment. Its role in camping is limited. Generally speaking, tents do not promise to keep warm. Camping warmth is the task of sleeping bags. The main functions of tents are windproof, rainproof, dustproof, dewproof and moistureproof, providing campers with a relative Comfortable resting environment. The early tent poles were often made of reinforced materials, which not only increased the weight of the tent, but also had poor resilience. The improved tent frame is made of fiberglass struts, which is lighter in weight, improved in resilience, and low in cost. Therefore, current tent manufacturers mostly use this material as struts, but the strength and sturdiness of the fiberglass struts Neither is ideal. If the strength is increased by thickening the fiberglass struts, it also increases the weight. The ideal strut is aluminum alloy material. The strut connected with high-strength alloy tubes is not only high in strength, but also light in weight and good in resilience. In particular, the EASTON struts made of aerospace aluminum materials have reached the state of all indicators, so they are mostly used for secondary tents. The main function of the tent bottom is waterproof, moisture-proof and dust-proof. The choice of bottom material also determines the grade of the tent. Low-grade tents usually use PE as the bottom material, and PVC is also used. What is required is low cost, double-sided coated PE, although it has waterproof and moisture-proof functions, but it is easy to wear and leak. . Winter is the nemesis of PVC backing, and PU-coated Oxford cloth as backing material greatly exceeds PE in terms of firmness, cold resistance, and water resistance. The pole of the tent is the skeleton of the tent. The quality of the skeleton material not only affects the life of the tent, but also affects the stability of the tent. The main performance indicators of the quality of tents are generally based on wind resistance, rain resistance and good stability. Alpine tents also require light weight and small size. A high-performance alpine tent usually uses a tear-proof structural fabric woven from nylon silk, plus a waterproof coating with a waterproof degree of more than 2000mm, and the seam is glued in the production process, which can ensure that you are in a heavy rain environment. , not affected by wind and rain. The choice of tent 1. Choose the outer tent and strive for high waterproofness. You can blow the fabric with your mouth to test its air permeability. Generally speaking, the air permeability is poor, and the waterproofness will be very good. 2. Select the inner account and strive for good air permeability. 3. The selection of struts requires high strength and good resilience. 4. The choice of primer should pay attention to water resistance and wear resistance. 5. The tent used for camping is better to choose a double-layer structure. 6. Specification selection It is better to have a door shed, or consider a slightly larger size. 7. Choose a tent with front and rear double doors, which is conducive to ventilation.
