The characteristics of moisture-proof pad
Said moisture pad is a small variety of outdoor equipment, because it is relative to other equipment, it's less valuable and cheaper prices. We say it is a species can not be ignored, it is because a relatively harsh outdoor conditions, solve the problem of moisture and warmth, for human health, it is of great significance. If you suffered cold, falling life-long root cause, would not go outside of our physical departure from the key body in mind. Therefore need to warn travelers, do not underestimate the moisture-proof pad, moisture-proof pad do not belittle the role of human health.
Moisture-proof pad varieties currently on the market are numerous, but no more than a few broad categories:
A. closed-cell foam pad:
This moisture-proof pad is the most common varieties of early, high-pressure polyethylene material, after forming foam, then cut to the specifications of different thickness of the sheet, it becomes our common moisture mat. This moisture-proof pad is characterized by closed, non-absorbent, usually 45 times the thickness of foam cut into 0.8-1.0, relatively inexpensive. Since durability is low, usually one-time use in foreign countries. China is a low-consuming countries, the consumption habits of people want to be used multiple times in order to reduce investment. Meet this requirement, some businesses to fold foam sections and high-power low-foam composite slice it, this is what we see in the market, double-color moisture pad, the outer layer of foam slices using a low power, so its greatly increased the wear resistance of the bottom. The cushion, there are two common specifications, one 180 * 50 * 1.2CM, one 180 * 50 * 1.0 CM, so the price will be slightly different, probably a difference of 20%.
B. EVA moisture-proof pad:
From its name, we know that it used the material, EVA, also known as back of the plastic, and closed-cell foam pad moisture compared with good elasticity, toughness and strong features, and hence the price difference is also greater, and the first moisture-proof pad almost double than the cost increase, but in the comfort and durability are greatly improved. However, its appearance, the average consumer is difficult to distinguish the difference, the real proof pad EVA material is rare in the domestic market, South Korea's GIANT brand EVA washboard pad, the price is almost close to 200.
C. XPE moisture-proof pad:
XPE moisture-proof pad, also known as the film half hole foam pad, the use of high pressure polyethylene material. This material was not as high-grade pure EVA material, however, strength, toughness and tensile strength better than a lot of closed-cell foam, but the water repellency not as good as closed-cell material, so producers when the production of such moisture-proof pad, in the process, by high temperature rigid crust deal to do to enhance water resistance. Such treatment by the crust (embossing) of moisture pad, not only enhances the aesthetics, water repellency, but also improve the toughness and the pattern of grooves, breathable feeling better. XPE is the introduction of new varieties of the past two years, the price is slightly higher than the closed-cell foam material, the use of comfort has obvious advantages, low moisture pad can be said that the ideal varieties. Common varieties are 180 * 55 * 1.0,180 * 55 * 1.2CM two specifications. Some businesses in order to enhance the thermal effect of moisture-proof pad, in which moisture-proof pad on the outside and then a layer of aluminum compound, aluminum body heat reflective role, in theory, should be warm and better. XPE is to produce by physical foaming, usually 30-45 times the foam. Multiple foam is lower, the better performance, from the appearance of seemingly no great difference between the mats, because the difference between multiple foam, the thickness difference, the price will be different. Common species on the market today have CAMPER, PURLAND brands are the varieties of low-fold foam.
D. inflatable moisture pad: (air bed)
This is called the air bed of the moisture pad is being used in the earliest use of water floating mats, and later used by some of the moisture pad camping, this fabric with cotton produced air bed scraping gum, moisture performance good, but because of larger, heavier quality, and inflation, the exhaust is too much trouble, so the family in the outdoor moisture pad is not a common species.
E. EPE moisture-proof pad:
EPE material often used as protective layer of packaged goods, because it has the function of waterproof, so it turned into moisture-proof outdoor camping mat, which is usually relatively thin moisture-proof pad, generally 2.5-3MM, to improve toughness and increase warm, but also often combined with aluminum, the general has done relatively large size, the common specifications are 1 * 2M, 1.5 * 2M, 1.6 * 2.2M, light weight, but poor anti-Ge, if the summer or warm season camping on the lawn use, is a good variety, generally two, three combined with a can, and if the cold hard ground or thick can be folded to its use.
F. Automatic Inflatable moisture pad:
Automatic inflatable pad is moisture proof pad aristocratic family, is a high-end products, the best cushions have sold more than 2,000 yuan, travel is often the first choice for outdoor tours of corruption, very comfortable to use, and its feeling like the Simmons family . In the production process, the moisture inside the pad is very good with the compression and expansion of the foam filling, extruded foam in the gas, turn off the gas nozzle to become the semi-vacuum pad, the volume becomes smaller. Open the gas nozzle, the role of air pressure in the outside world, the foam expansion, you can automatically pad of air to breathe, so called auto-inflatable mattress, full of air, moisture pads have a very good flexibility.
Such as selection of different moisture-proof pad, divided into high, medium and low grade. Low-grade PVC coated polyester is generally used silk, so the quality will be heavier. Often used in high-grade PU coated polyester silk, with high quality foam inner core, so a sense of compression and resilience are very good. The way the bond can be divided into edge, semi-adhesive glue and all three methods, high-end goods are handled with full adhesion, the air cushions seem seamless after charging is finished, so comfort and very good. Because of this inner cushion filled with a sponge, generally the volume will be relatively large, in order to reduce the volume of cushion, some varieties to dig into honeycomb sponge inside, when the strong compression, the volume will be greatly reduced, and also reduce a lot of weight, However, due process is relatively complex, so the price will be expensive.
Automatic inflatable moisture pad will be very comfortable, but also the need to pay attention to the use of skills. The general state of auto-inflatable, flexible will not be satisfactory. Therefore, before using automatic inflatable 2-3 after the tone should be completed in order to enhance its flexibility, it should be noted that qi must not be too much, excessive force gas expansion, will tear adhesive layer, And once the air bag, using the not so comfortable.
Understanding of the characteristics of the family after the moisture pad, you can choose according to their needs. In fact, not only for moisture proof pad, which at least two functions, one warm, and second, anti-Ge. This is related to the thickness and moisture-proof pad, if little opportunity for outdoor travel, and is the warm season, a common enough moisture-proof pad, you can spend fifty or sixty dollars on a pretty good buy. If many opportunities for outdoor travel and use in harsh environments, I think you should not begrudge the RMB, because the comfort and take care of themselves is the first.
