In the industrial production is the most inseparable from the woven bag manufacturers to produce woven bags, do not say that the other function of the woven bag alone in our industrial transport if there is no woven bags will greatly increase our working hours and economic benefits, so We always choose in the industrial production of woven bags, woven bag selection is a very important element, we choose the time in the choice of woven bags to observe the appearance of woven bags, because it is absolutely a good quality of woven bags factor.
The appearance of woven bags is not only the most beautiful is the feel, woven bag factory production of PP flat woven fabric feel more solid, very wide, rough some. HDPE flat woven fabric feel soft, smooth, not dense. In the PP flat wire material to add calcium masterbatch, feel very wide, PP less HDPE will make it more soft. Woven Bag Flat wire narrow, weaving flat, soft to the touch, flat wire width, woven fabric folded when more than silk, feel rough.
The use of strong thick line for packaging, pin uniform, which can improve the ability of woven bags, woven bags of the compression and sealing are high.
Woven bags of bright color, Woven Bag the use of materials are a new material, the quality of woven bags, packaging products from the beautiful and generous.
Woven bags of raw materials are PP (polypropylene), PE (polyethylene) composition, 51 period, PP market is more dull. Turnover reaction is not very ideal. Xiaobian that the PP market downturn, and the annual May to September of the woven bag market off-season, low demand, the volume naturally low. Of course, with the continuous decline in crude oil prices, coupled with individual market mentality is not very stable, Woven Bag resulting in some PP market prices have declined slightly, but the overall market changes little, the impact is minimal In the next few months, Xiaobian PP market turnover that space is limited, if no special circumstances, the market will maintain a long period of steady state.
Woven bags with light weight, good electrical insulation, good corrosion resistance, easy processing and other characteristics. The woven bag has some common features of PP and its own characteristics. as follows:
1, light weight
PP is usually relatively light, the density of woven bags is about 0.9-0.98 g / cm3. Commonly used plastic braid, if not added filler, that is equal to the density of plastic. Plastic weaving application of plastic density of 0.9-0.91 g / cm3. Normally the braid is lighter than water.
2, high breaking strength
The knitted fabric is a flexible, high fracture strength material in plastic products, which is related to its molecular structure, crystallinity, draft orientation, etc., and is related to the type of additive. If the strength (strength / specific gravity) Measure the plastic braid, Woven Bag which is higher than or close to the metal material.
3, good chemical resistance
The braid has good corrosion resistance to inorganic and organic materials, below 110 degrees Celsius, and it does not affect it for a long time. It has a strong chemical stability for solvents, greases and so on. When the temperature rises, carbon tetrachloride, xylene, turpentine, etc. can swell it. Fuming nitric acid, fuming sulfuric acid, halogen elements and other strong oxides will make it oxidation, Woven Bag it is strong alkali and usually acid corrosion resistance is better.
4, good wear resistance
Pure plastic braid between the friction coefficient is small, only about 0.12, similar to nylon, to some extent, between the plastic woven fabric and its friction, with a lubrication effect.
5, electrical insulation is better
Pure plastic braid is an excellent electrical insulator. Because it is not moisture, not affected by the moisture in the air, the breakdown voltage is high, his dielectric constant of 2.2-2.6, its volume resistance is high, plastic woven fabric insulation is good, Woven Bag not Equal to use it as an insulating material.
6, environmentally friendly
At room temperature, the plastic woven fabric is completely free from water erosion, 24 hours of water absorption less than 0.01%, water vapor permeability is also very low, low temperature, it becomes brittle, easy to crack. Plastic braid does not mold.
7, poor anti-aging ability
Woven bags of anti-aging ability is poor, especially woven bags lower than the polyethylene woven bags. Its aging problem is mainly the itching of the aging, photodegradation. The poor resistance of the woven fabric to the aging resistance is a major lack of its impact on the life and application of the woven bag.
