In recent years, we have seen the rapid development of science and technology in our great motherland. This made me feel extremely proud for me as a Chinese. With the advancement of technology and the progress of people, we will join the Chinese cutting machine trading network to make progress together. Join the hotline, we look forward to your call.

Recently, China's first LCD short-circuit ring laser cutting machine was successfully developed by the Changchun Guanghua Microelectronics Equipment Engineering Center Co., Ltd., which is controlled by the Changchun Institute of Optics and Mechanics, Chinese Academy of Sciences. It is said to be the first LCD short-circuit ring developed by China. The laser cutting machine has the advantages of reasonable design scheme, advanced performance, rapid and accurate image recognition and alignment, high precision of rapid motion control, and smooth and clean laser cutting marks.
According to reports, the world's first short-circuit-ring laser cutting machine was born in Japan in the late 1990s. It was introduced with the advent of TFT-LCD technology. This equipment is an indispensable key equipment in the production process of liquid crystal TFTs. At present, only Japan can produce.
With the rapid development of China's LCD industry, the demand for short-circuit-ring laser cutting equipment for LCD screens has increased sharply. However, the long period of foreign orders and the high price are far from satisfying domestic demand in China. In May 2003, Changchun Guanghua Microelectronics Equipment Engineering Center Co., Ltd. started the development of the equipment and solved the technical problems in the fields of optics, machinery, electricity, computing, and imaging in a relatively short period of time. Developed China's first short-circuit ring laser cutting machine.

Butyl Acrylate is an organic compound with the formula C4H9O2CCH=CH2. A colorless liquid, Butyl Acrylate Monomer is the butyl ester of acrylic acid. N Butyl Acrylate is used commercially on a large scale as a precursor to polybutylacrylate, which is used in paints, Solvent Raw Material sealants, coatings, adhesives, fuel, textiles, plastics, and caulk.
Butyl Acrylate Price can be produced by the acid-catalyzed esterification acrylic acid with butanol. Since it polymerizes easily, commercial preparations may contain a polymerization inhibitor such as Ethylene-Vinyl Acetate hydroquinone, Boric Acid Flakes phenothiazine, or hydroquinone ethyl ether.
Butyl Acrylate Cas 141-32-2 is of low acute toxicity with an LD50 (rat) of 3730 mg/kg.
In rodent models, N-butyl Acrylate is metabolized by carboxylesterase or reactions with glutathione; this detoxification produces acrylic acid, butanol, and mercapturic acid waste, which is excreted.
N-butyl acrylate (BA) is the largest-volume acrylate ester used in the production of all-acrylic, vinyl acrylic and styrene acrylic copolymers. BA offers price-value and accounts for about 60 percent of the global acrylic ester monomer demand, with a consumption volume of over 2,000 kilo tons.
