Product Description: Air caster rigging system has more than one advantage, because air bearing system has many advantages, so air casters load moving equipment is used in various fields. The smoothness of the air skates is an important attribute that differentiates from other moving tools. Our company produces air bearing turntables and sells air bearing movers by ourselves, so as to ensure our after-sales service Air caster can be sold directly, with all the accessories, including four or six air cushions, main and auxiliary air ducts ,a gas-pressure meter and so on. When using the air bearing movers, the air pump is needed. If the machine is too heavy, the aircraft transporters can be put under the machine to be moved with the help of a jack. Air skids used to move many tons of equipment and machinery within the plant or on a work site, Air casters is perfect for frictionless and omni directional movement. more>

Product Description: White Steam Reeled Silk 20/22D Silk Yarn Spun Silk Yarn Mulberry Silk YarnThe manufacturing process of white steam-reeled silk is divided into hand reeling and machine reeling. Hand reeling mostly uses high-quality cocoons, which are soaked in hot water and then drawn by hand, winding the silk onto a reel. In contrast, machine reeling is a more modern process that increases production capacity, ensures more uniform fiber fineness, and liberates a large amount of labor. The production process of raw silk includes: cocoon mixing → cocoon peeling → cocoon selection → cocoon boiling → reeling → rereeling → finishing → inspection. Essentially, it involves soaking the cocoons in high-temperature water, cooling them, drawing the silk, extracting the filaments from the cocoon layers, and then combining several filaments according to the required linear density to spin industrial silk, commonly known as white steam-reeled silk. more>

However, if users have other needs, they can upgrade to dual-line or triple-line. As is well known in the pricing rules of domestic servers, the more lines, the higher the cost. But both Wenzhou triple-line servers and BGP integrate carrier lines. So, what is the essential difference between the two?First, Price DifferenceThis starts with the method of upgrading to triple-line. Generally, the default single-line Wenzhou server is upgraded to triple-line by adding two IPs from other lines, which is commonly referred to as triple-line triple-IP. The cost of IPs for domestic servers is relatively high. Upgrading a Wenzhou server to triple-line requires an additional 200 yuan on top of the original configuration price. In contrast, BGP lines only require one IP. The original configuration price remains the same when choosing BGP lines, with no additional costs. Therefore, in terms of price, Wenzhou BGP lines are slightly cheaper than Wenzhou triple-line servers.Second, Line SpeedIn terms of line speed, BGP lines provide equally fast access for users on any domestic network. Even if one line fails, the BGP protocol will switch to the optimal line for user access, ensuring a good user experience. On the other hand, Wenzhou triple-line servers resolve the website to three carrier IPs. For example, if a Unicom user accesses the website, all access nodes are Unicom, which also ensures fast speed. However, if the Unicom line fails, it will affect the user's access experience. Therefore, in terms of line speed, Wenzhou BGP servers offer the best user experience.So, compared to Wenzhou BGP lines, Wenzhou triple-line servers have some inherent differences. If no failures occur during use, there is no issue. But once a problem arises, the difference becomes significant. Users should carefully choose the line type when selecting Wenzhou servers. more>

Uses: L(+)-Tartaric acid is widely used as an acidulant in beverages and other foods, including wine, soft drinks, candy, bread, and certain gelatinous sweets. Due to its optical activity, it serves as a chemical resolving agent for the resolution of DL-aminobutanol, an intermediate in the production of anti-tuberculosis drugs; it can also be used as a chiral raw material in the synthesis of tartaric acid derivatives. Utilizing its acidity, it acts as a catalyst for resin finishing of polyester fabrics and a pH regulator in the production of oryzanol. Owing to its complexing properties, it is employed as a complexing agent, masking agent, chelating agent in electroplating, desulfurization, pickling, as well as in chemical analysis and pharmaceutical testing, and as a dye resist in printing and dyeing. Because of its reducing nature, it is used as a reducing agent in chemical mirror making and as a developer in photography. It can also complex with various metal ions, making it suitable as a cleaner and polishing agent for metal surfaces. more>

Product Description: GPU MF polyurethane mortar flooring is a new type of pollution-free ground material. Its composition meets specific usage requirements (such as comfort in high-end conference or entertainment centers, corrosion resistance and wear resistance in industrial and mining enterprises), making it particularly suitable for floor coatings in various industrial workshops, food processing plants, slaughterhouses, parking lots, electronics, warehouses, pharmaceuticals, and other enterprises that require anti-slip, anti-corrosion, and wear-resistant properties.This type of floor coating primarily uses polyurethane resin as the main film-forming material, combined with solvents, pigments, catalysts, and other materials to form a four-component water-based polyurethane mortar flooring system. As a result, the composite material possesses all the advantages of both organic polymers and inorganic concrete materials, such as excellent chemical corrosion resistance, heavy impact resistance, and thermal shock resistance. Moreover, compared to traditional epoxy floor coatings, this type offers greater flexibility, wear resistance, and ease of construction. It is very convenient to apply, saving significant time, and can typically be used within 4 hours after application, reducing various renovation challenges for enterprises. more>
