What are the functional curtains:
UV protection curtains: The right amount of ultraviolet light has certain benefits to the human body and living things, but excessive ultraviolet radiation can damage the living organisms and reduce the life of interior decorations and furniture.
Most curtains have certain UV protection functions, especially thick and high-density fabrics can block most of the UV rays, and some fibers such as hemp and bamboo fiber also have good UV protection.
For thin curtains that require better light transmission, and hope to shield ultraviolet rays, inorganic or organic anti-UV agents can be added to the fabric, among which inorganic oxides are used more, such as zinc oxide, titanium dioxide, silicon oxide, and aluminum oxide. , magnesium oxide, etc. Such mineral micropowders, especially when they reach the nanometer scale, have a particle size similar to that of ultraviolet rays, a large specific surface area, and a high surface energy, which can reflect and scatter some ultraviolet rays. At the same time, after some electrons are activated, a series of chemical reactions occur that convert energy into heat and light, and still have normal light into the room.
Reflective and full blackout curtains: These two types of curtains are generally produced using coating or plating techniques. Reflective curtains require most of the sunlight to be reflected out, reducing room temperature.
At the same time, an appropriate amount of light enters the room for illumination. This kind of curtain fabric can be coated with silver powder or vacuum aluminum on the outdoor side to produce a strong reflection effect, reflecting sunlight to the outside. The full blackout curtain can be coated by multiple layers, and the foamed light-shielding layer and the light-colored surface layer are separately coated on the fabric, which can achieve full shading and beautiful appearance.
Antibacterial insect-resistant curtains: Antibacterial curtains can inhibit the growth of bacteria and molds, eliminate the odor caused by bacterial growth, and prevent the spread of certain diseases.
Curtain materials include: natural antibacterial fiber, such as chitin fiber, hemp fiber, bamboo fiber, etc.; metal fiber, such as silver, copper, nickel-chromium alloy, etc.; more applications are in the fiber added antibacterial agent fiber. Commonly used antibacterial agents are inorganic antibacterial agents and organic antibacterial agents. Inorganic antimicrobial agents include primarily silver, copper, zinc ions and certain metal oxides such as ZnO and TiO2. There are many varieties of organic antibacterial agents, such as organometallic compounds, halides, isothiazoles, quaternary ammonium salts, diphenyl ether compounds, and organic nitrogen compounds. The insect-repellent effect can be achieved by adding an insecticide during the production of the curtain fabric.
Negative ion curtains: With the expansion of the city, the green area is relatively reduced, and the amount of negative ions in the air is low. Negative ion curtains can emit more negative ions beneficial to the human body under certain temperature, humidity, light and motion conditions.
Adding some mineral micro-powders that can generate negative ions in the air, such as tourmaline, skeletal stone, opal, etc., can promote the generation of negative ions. The negative oxygen ion is an oxygen molecule that captures an electron. The negative oxygen ion can be combined with positively charged particles such as bacteria, dust, and smoke, and aggregates into a ball to fall to the ground, thereby killing and eliminating odor. Such as cigarette smoke, odor generated by harmful gases released from the decoration materials. Studies have shown that the negative ion functional fabric releases the largest amount of negative ions under UV irradiation, when the fabric is honeycomb structure, the latitudinal density of the fabric is 20/cm, the atmospheric temperature is 20 °C, and the relative humidity is 55%. When the concentration of negative oxygen ions in the air reaches 20,000/cm3, the amount of dust in the air is reduced by more than 98%.
Far-infrared curtains: Far-infrared textiles can absorb the heat energy of the human body or the outside world and convert them into far-infrared rays, thus increasing the temperature of the surface of the fabric, promoting blood circulation and metabolism of the human body, and having a certain health care effect.
The far-infrared emissivity of far-infrared fabrics is about 10% larger than that of ordinary fabrics, and most textiles with far-infrared emissivity greater than 85% are called far-infrared textiles. For far-infrared curtains, fabrics with far-infrared ceramic powder are used. The addition method can be added during the spinning of the chemical fiber, or the finishing process can be used to attach the far-infrared ceramic fine powder to the fabric, and the emissivity thereof varies according to the variety of the fine powder and the amount of the added powder. At present, most of the micro-powders with a composite function can generate negative ions and emit far-infrared rays, and can increase indoor temperature, inhibit bacteria, and purify the air.
Fragrance and Deodorant Curtains: Adds scented microcapsules to the curtain fabric for a faint scent over a certain period of time.
Certain fragrances have certain health functions for the human body, such as refreshing or hypnosis, suppressing or promoting appetite, slowing down headaches, calming the heart and so on. The choice of flavor type varies from person to person, not too thick, but it must be durable and washable. Deodorant curtains are made by adding some antibacterial and adsorption functions to the curtain fabric, such as bamboo charcoal, which can adsorb and decompose the odor to a certain extent.
Smart curtains: Smart curtains are curtains with certain self-reaction, adjustment and control functions.
For example, the light intensity, air humidity, and room temperature are automatically adjusted according to the indoor environment. Using phase change microcapsule technology, the heat in the sun can be absorbed during the day and released at night. The light-storing material is added to the curtain fabric to absorb the light energy during the daytime, and there is still enough light after the light is turned off at night to facilitate the slight activity at night. This kind of automatic adjustment of light transmittance according to the situation of sunlight can reduce the use of air conditioner in summer. In winter, its special material ensures that the indoor temperature is not lost, and it should be an environmentally-friendly curtain.
Non-tapping screws are machine Screw, the pieceworker to be fastened must be tapped with taps in the screw hole in advance to match the screw threads.
The difference between tooth screws and other screws depends on whether they can be used together with nuts. Tooth screws can be used with nuts. And relative to the screws of other teeth, there are self-tapping screws. The nut of this kind of screw has no bow teeth. As for the standard teeth and fine teeth are only different pitch, it is the nut of the machine screw
