Beihang Fluid Systems (Shanghai) Co., Ltd. will release new BEIONFLUID multi-pass injection valves at the Munich Analytical Exhibition in October . The multi-pass injection valve provided by Beyond Fluid is divided into high-pressure manual injection valve and medium-low pressure electric injection valve. These two injection valves are widely used by instrument manufacturers in various fields of precision analysis.
High pressure manual injection valve H6-7725i is an important accessory for all types of liquid chromatography instruments, mainly used in manual injection parts of the instrument. The injection valve is a 6 -position, two-position, manual injection valve with one injection port. This manual injection valve uses a 316 stainless steel body and uses PEEK , Vespel, and ceramics as the contact materials. It has a continuous flow design that maintains fluid flow continuity during sampling and injection switching, greatly reducing the instantaneous pressure. Impact on system interference.
The R series multi-pass sampling valve is a new sampling distribution valve from Beyoncus Fluids. The standard flow path configuration consists of 4- way switching, 4- way distribution, 4- way mixing, 6- way distribution, and 6- way ring and 10- hole injection. composition. The direction of the fluid circuit is changed by the stepper motor controlling the rotary shaft inside the valve body. The photoelectric position sensor inside the injection valve controls the rotation accuracy and position calibration. The contact part is only the valve body and the shaft part, and it is a tetrafluorochemical inert material. It is mainly used for sample processing, split mixing, injection injection and many other applications.
Beihang Fluid's engineers will present the advantages and features of BEIONFLUID multi-pass injection valve at the Shanghai New International Expo Center in October . You are welcome to visit our booth at that time.

Titanium Dioxide(TIO2)
Titanium dioxide is an important inorganic chemical pigment, the main component is titanium dioxide. The production process of titanium dioxide has two process routes: sulfuric acid method and chloride method. It has important applications in coatings, inks, papermaking, plastics and rubber, chemical fiber, ceramics and other industries.
It has two types: rutile type (Rutile R type) and anatase type (Anatase A type). The rutile crystal structure is compact, relatively stable, and has low optical activity, so it has good weather resistance, and has high hiding power and decolorizing power.
Titanium dioxide is widely used in coatings, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemicals, medicine, food and other industries.
The coating industry is the largest user of titanium dioxide, especially Rutile Titanium Dioxide, most of which is consumed by the coating industry. The paint made of titanium dioxide has bright colors, high hiding power, strong tinting power, low dosage, and many varieties. It can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the paint film to prevent cracks. Prevent the penetration of ultraviolet rays and moisture, and extend the life of the paint film.
The plastics industry is the second largest user. Adding titanium dioxide to plastics can improve the heat resistance, light resistance, and weather resistance of plastic products, improve the physical and chemical properties of plastic products, enhance the mechanical strength of the products, and extend the service life.
The paper industry is the third largest user of titanium dioxide. As a paper filler, it is mainly used in high-grade paper and thin paper. Adding titanium dioxide to the paper can make the paper have better whiteness, good gloss, high strength, thin and smooth, no penetration during printing, and light weight. Titanium dioxide for papermaking generally uses Anatase Titanium Dioxide without surface treatment, which can act as a fluorescent whitening agent and increase the whiteness of paper. However, laminated paper requires the use of surface-treated rutile titanium dioxide to meet the requirements of light resistance and heat resistance.
Titanium dioxide is also an indispensable white pigment in advanced inks. The ink containing titanium dioxide is durable and does not change color, has good surface wettability and is easy to disperse. The titanium dioxide used in the ink industry has rutile type and anatase type.
The textile and chemical fiber industry is another important application field of titanium dioxide. Titanium dioxide for chemical fiber is mainly used as a matting agent. Since the anatase type is softer than the gold red type, the anatase type is generally used. Titanium dioxide for chemical fiber generally does not require surface treatment, but in order to reduce the photochemical effect of titanium dioxide and prevent the fiber from degrading under the action of titanium dioxide photocatalysis, surface treatment is required for some special varieties.
The enamel industry is an important application field of titanium dioxide. The enamel grade titanium dioxide has high purity, good whiteness, fresh color, uniform particle size, strong refractive index and high color reducing power, and has strong turbidity and Opacity, make the coating thin, smooth and strong acid resistance after enamelling. It can be evenly mixed with other materials in the enamel manufacturing process, does not agglomerate, and is easy to melt.
The ceramic industry is also an important application field of titanium dioxide. Ceramic grade titanium dioxide has high purity, uniform particle size, high refractive index, excellent high temperature resistance, and does not change ash at 1200°C for 1 hour. High opacity, thin coating, light weight, widely used in ceramics, construction, decoration and other materials.
