Specifications, types and materials of tents
Types, models and composition of tents
Tent generally consists of two parts: the tent body and the bracket. The entire tent is made of military green canvas and Oxford cloth (warm in winter and cool in summer), with felt in the middle and lined with white cloth. The workmanship is based on military tents. The windows are equipped with screens to prevent mosquitoes and provide ventilation. The windows are equipped with plexiglass panels, which can be used to prevent wind and light in the summer, and can be used to provide light and heat preservation in the winter. The bracket adopts steel frame structure. It is used for long/short-term residential use in the field during field inspections, camping, exploration, construction, disaster relief, and flood control.
Types of tents: military tents, construction tents, civilian tents, disaster relief tents, etc.
Commonly used models of tents are: No. 3 standard tent: 3M×2M, 3M×4M, No. 4.5 standard tent: 4.5M×5M, 4.5M×7.5M, 4.5M×10M, No. 5 standard tent: 5M×4M, 5M ×6, M5M×8M, No. 5 special tent: 5M×4M, 5M×6, M5M×8M
Classification of tents
This is a rather troublesome problem because there are too many different ways of classifying tents on the market. Some are divided by the number of users, such as single-person tents, double-person tents, four-person tents…; some are divided by seasons, such as three-season tents, four-season tents, mountain tents…; and some are divided by structure, such as yurt type, tunnel style, frog style…; there are also tents divided according to poles, such as single-pole tents, two-pole tents, three-pole tents…; there are also inner hanging tents, external hanging tents, glass pole tents, aluminum pole tents, single-layer tents Tent, double-layer tent…Oh, I have a headache. We don’t care about so much, let’s use common terms to distinguish tents. For example, a tent is a two-pole camping tent for 2-3 people. You can roughly see the purpose of this tent, and then pay attention to the waterproofness and weight. . The more popular tents currently on the market are double tents or 2-3 person tents with double poles, a rainproof capacity of PU1500MM, and a weight of about 3KG. Prices vary greatly depending on brand, material, and workmanship. There are several types of tents that you need to pay attention to when purchasing: tunnel tents and single-pole tents. This kind of tent must be ground nailed when it is set up, otherwise it will not be used. It may be difficult to set up in some cases, so you must take this factor into consideration when purchasing this kind of tent; Alpine tents, this kind of tent emphasizes wind resistance and has a snow skirt design. It is also generally heavier and is generally used for camping. It will be more painful to use it sometimes. If you only use it for camping, you don’t want to buy such an impractical thing just for the sake of face; the internal hanging tent, E-225 was popular in the early years, that is the internal hanging tent, this kind of tent On rainy days, you can build the outer tent first, and then hide inside to hang the inner tent, which is good. But at the same time, it also has a fatal weakness, that is, when the weather conditions are good, the inner tent cannot be used alone to achieve good ventilation effects, especially when camping at the beach. Single-layer tents, this kind of tent has basically been eliminated and is only still sold in some fishing gear stores. The disadvantage is that it has poor waterproofing and poor breathability (except for high-tech waterproof and breathable fabrics). The material of the tent is mainly divided into four types: outer fabric, inner fabric, tent poles, and tent bottom fabric. Talk about each one. As for the outer fabric, most camping tents now use nylon cloth coated with PU fabric to achieve rainproof performance (mostly low-priced tents also use polyester). Nylon cloth is mainly divided into two types: 190T and 210T. The larger the value, the better but the heavier the weight. The PU coating is expressed in **MM units to indicate the degree of rain resistance. The general standard is that anything over 1200MM can be completely rainproof, so most tents on the market now have a rainproof rating of 1500MM. But whether this value is accurate depends on the conscience of the manufacturer. One thing you can know is that the higher the waterproofness, the greater the weight. If it is lower than 1200MM, it is basically certain that its rain resistance is not good, and it is usually not considered. In addition, now that VAUDE has entered China, it has brought in tents made of silicone fabrics, which are said to be 3000MM rainproof and extremely light. Its seams are not taped. According to VAUDE company people, this kind of thread will expand and block the seams when exposed to water. The inner tent is much simpler. Now it is mostly made of nylon or polyester fabric, which is not waterproof but breathable. Some are also designed with a lot of gauze to increase breathability. Tent poles are nothing more than fiberglass poles and aluminum alloy poles. Aluminum alloy poles are divided into 6061, 7075, Easton, etc., but the common advantages are that they are light, strong, and elastic, and they have a cross-section after breaking, so they can be repaired on the spot and reused. The only drawback is that it’s expensive. Haha, fiberglass poles are just the opposite. The only advantage is that they are cheap. When it breaks, the fracture is like splitting bamboo, and it is difficult to repair on site. This is a troublesome point when using it outdoors. The bottom material of the tent used to be made of PE, but now it is mostly made of nylon or Oxford cloth, and then coated with PU to make it waterproof. It is often much more waterproof than the outer tent. The main reason is that after people enter the tent, there will be a lot of pressure on the bottom of the tent.
Cleaning and maintaining the tent after use is also very important. It is related to the service life of the tent and also directly affects its future use. Cleaning the tent should be carried out according to the following procedures:
1. Clean the bottom of the tent and wipe away the sediment. If there is any pollution, lightly scrub it with clean water.
2. Dry the tent’s interior and exterior tents in the sun, and then put them away after they are dry again. If you do not have time to dry the tent, remember not to store it for a long time to avoid coloring and mildew. Once conditions permit, dry the tent immediately.
3. Clean the sediment from the support pole.
4. Check the tent accessories and their integrity.
5. It is not advisable to use detergents to clean so as not to affect the waterproof effect.
Types of tents
��PU ages to avoid deterioration in waterproof performance;
3. When folding the tent, roll it up slowly and in a direction to drive away the air in the tent. If the air rolls up the tent without an outlet, the air can only break through the waterproof layer and come out, which will greatly affect the waterproof performance. 82MWN86
