Six protective clothing types and functions
1 Flame retardant protective clothing
Many smoldering protective suits have now escaped traditional heavy raw materials. For example, wool products and leather use high-performance self-turning fiber products such as meta-aramid, ceramic fiber, para-aramid and other high-modulus fibers, in which the carbon fiber has a small specific gravity, heat resistance, impact resistance, chemical resistance, and conductivity , Under anoxic conditions, can withstand 2 000 °C high temperature, and smoldering radiation resistance, widely used.
2 Bus protective clothing
The public utilities and transportation sectors also make heavy use of highly visible garments. Most of these garments use fluorescent products and higher grade retroreflective materials, often made into strips, ribbons, and attached to other fabrics, such as safety nightwear. Its types include clothes, caps, pants, vests and shoes. Its main raw material is the cloth that is woven with fibers in units of micrometers. It is called light-emitting fiber cloth. When the car lights are shining, the cloth will immediately reflect strong light and can provide high visibility at night and signal the driver. Decelerate immediately.
3 Military protective clothing
The protective clothing used by the military department is mainly made of composite multi-fiber textiles containing high-density chemical fiber and natural fiber woven fabrics as well as activated carbon nonwovens and foaming materials. It can prevent nuclear hazards and prevent biochemical hazards. According to the information, protective clothing with multi-functional anti-biochemical and harmful gases has been introduced. The protective suit is embedded with a biochemical sensor and an ultramicro-induction device. The biochemical sensor can monitor the heart rate, the blood pressure, the body surface temperature and many other indicators of the soldier. The ultramicro-induction device can identify the body surface bleeding site and make the surrounding military uniforms. Expansion and contraction play a role in hemostasis. The injuries of the soldiers can also be transmitted directly to the doctors in the field. The military doctors can send instructions through the Internet to release the self-contained antibacterial materials or blood clotting drugs in the protective clothing to the injured area for simple treatment.
The fabric of the protective clothing incorporates a kind of luminous micro-particles, which can perceive the color of the surrounding environment and make corresponding adjustments, so that the protective suit becomes a concealed protective color consistent with the surrounding environment. Body armor is made of many high-performance fibers and materials including films. Another kind of glass fiber made of protective cloth, with 4,000 tons pressed into a composite material, with bullet-proof, sealed, waterproof and other special features. Use this protective cloth to do body armor, bulletproof helmets and bulletproof liners.
4 medical protective clothing
At present, the largest amount of medical protection is taken, such as surgical masks, facial mirrors, surgical gowns, hoods, gloves, shoes, anti-SARS virus suits, and many protective equipment such as curtains, sheets, and insulation barriers. These protective clothing should ensure easy operation, safety, anti-virus, anti-bacterial and comfort, but also have the ability to prevent accidental cutting, but also to avoid water washing, reduce the surgical infection and other functions, and focus on incineration after use to effectively prevent cross-infection. General non-woven fabrics are produced by dipping, foam impregnation, hot-rolling or wet processes. The weight of the fabric is 1550 g/mz, which requires a soft hand, good tensile strength and breathability.
5 radiation protection protective clothing
The radiation protection work clothes are mainly used in the nuclear industry for post-processing plant inspections, and are worn by operators who have serious radioactive surface contamination and other locations where the concentration of acid and alkali is not high.
Radiation protective clothing fabrics can be manufactured by the non-woven processing method of immersion, and the weight of fabrics is better around 80 g/mz. Breathable antivirus clothing should have a double-layered structure, and the outer layer function is to bear various venoms that are attached to the clothing with strength and spreading. The inner layer function is to adsorb venom and poisonous gas and block it from passing through so as not to invade the skin. Used as the inner layer material must be treated with fluorine and activated carbon coating, due to the physical adsorption of activated carbon, non-woven fabrics made of breathable anti-virus clothing, in addition to possessing the advantages of anti-virus, breathable, light, soft and obstructive It is cheaper. It can be used once.
6 Other protective clothing
Other protective clothing is protective clothing for the construction industry and special industries, such as for fire protection, heat insulation, anti-smashing and grain and oil industries, electronics industry, bio-engineering, pharmaceutical industry, and other clean rooms for dust, particulate, and antivirus Moonwear is growing at a rapid rate.
Juice Extractor
The food thinkers have designed an extra wide fruit chute for juicing whole apples, oranges and other large fruits saving you chopping time. The automatic pulp ejection feature and easy to clean design from the food thinkers makes tidying up quick and hassle-free. Almost all Breville juicers are designed to juice whole fruit without chopping or slicing. Some juicers also have Breville's unique extra wide chutes that are another 25% larger (85mm diameter) to accept even bigger fruit. A thinner mesh reduces the surface area between the fruit and the cup. These unique Italian made filter baskets have almost 40,000 tiny pores. All Breville juice extractors automatically eject the dry pulp into a collection basket while juicing. Most Breville juicers also have this pulp collection basket located externally for easy clean up and minimal down time when juicing many litres at a time.Smooth, rounded parts without food traps prevent pulp from sticking and make rinsing under the tap fast and simple. The easy clean models also come with a specially designed scrubbing brush to clean the filter mesh quickly and easily. powerful full copper motor from 300W-650W/110V-240V/50Hz-60Hz
