Uv Fluorescent Short Fibre

Optical brighteners, also known as fluorescent whitening agents (FWAs) or optical brightening agents (OBAs), are chemical compounds used in various industries, primarily in textiles, paper, and detergents. These substances absorb ultraviolet (UV) light and re-emit it as visible blue light, making colors and whites appear brighter and more vivid. Optical brighteners are often added to laundry detergents to give the illusion of cleaner and whiter clothing by enhancing their visual brightness. They are also used in the paper industry to improve the brightness and whiteness of paper products. Optical brighteners' ability to improve the appearance of materials under certain lighting conditions makes them valuable in enhancing the visual quality of a wide range of consumer and industrial products.

We can offer a range of UV Fluorescent Pigment for security, identification, coding and anti-counterfeiting applications.
These pigments are neutral in color, with a white to off-white powder appearance, and are not noticeable when incorporated into security inks, fibre and papers. When irradiated with UV light, these pigments emit fluorescent radiation of yellow, green, red, blue colors and so are immediately identifiable.

Some of the common applications are in postage stamps, currency notes, credit cards, lottery tickets, security passes, etc.
A similar range of pigments are also offered for architectural decoration applications, such as in hotels and restaurants, discotheques and night clubs, gymnasiums and other public entertainment places for outstanding visible effects. Details are available on request.

Introduction:

Polyether polyols are key components used in the production of polyurethanes.
Polyether-based polyurethanes exhibit enhanced hydrolytic stability and excellent resistance to weak acids and bases compared to polyester-based polyurethanes.
Polyether polyurethane can be divided into soft foam polyether, rigid foam polyether, and elastomer with polyether according to the performance of polyether products.
However, polyether-based polyurethanes are more susceptible to UV radiation and provide poor resistance to oils and fuels compared to polyester-based polyurethanes.
Application:
Polyether polyols' major use is in polyurethane foams. Flexible foams are primarily used in cushioning applications such as furniture, bedding and car seats, and in carpet underlay. Rigid foam's largest consumer is the construction industry where it is mostly used for insulation. Rigid foam is also used in commercial refrigeration and packaging. Smaller uses for polyether polyols include elastomers, adhesives and sealants, surface coatings and polyurethane fibres.

FDR-3301 UV fluorescence sulfur analyzer
Scope
This instrument is a new generation of precision instruments developed in combination with the principle of UV fluorescence measurement and computer technology. It is the most advanced total sulfur analyzer in China. It conforms to ASTM D5453, SH / T 0689 and other standards. The instrument complies with national refined oil Arbitration standard for determination of total sulfur content. It widely used in the determination of crude oil, hydrocarbons and engine fuel, LPG, plastics, petrochemical products, food and so on.
The instrument uses the principle of ultraviolet fluorescence measurement, when the sample is introduced into the pyrolysis furnace, the sample undergoes the cracking oxidation reaction, in which the sulfide is quantitatively converted into sulfur dioxide, carried by the carrier gas, the moisture is removed by the membrane dryer, (SO2 *), when the SO2 * return to the steady state of sulfur dioxide emission fluorescence, the release of energy received by the photomultiplier tube, and then amplified by the micro-current amplifier, and then to the SO2 * The amount of sulfur dioxide is proportional to the total sulfur content in the sample, so the total sulfur content in the sample can be determined by measuring the luminous intensity of the sample.
