The invention discloses high chemical resistance borosilicate glass, comprising the following components based on oxides in percentage by weight: 71-75 SiO2, 3-6 Al2O3, 8-10 B2O3, 4-10 Na2O and 0-2.5 K2O, 0-1.2 CaO, 0-1 MgO, 1-3 BaO and 0-0.3 CeO2, wherein Na2O+K2O ranges from 7 to 10, and CaO+MgO ranges from 0 to 1.2. The invention has the following advantages: 1. As2O3, Sb2O3, BaSO4 and other harmful substances are not used in constituents, and the borosilicate glass can be used as a material for packing medicines; and 2. tested by experiments, the high chemical resistance borosilicate glass prepared from the constituents by the traditional production equipment has the coefficient of heat expansion ranging from 5.0*10<-6> K<-1> to 6.0*10<-6> K<-1>, the inversion temperature Tg ranging from 520 DEGC to 572 DEGC, the softening point ranging from 765 DEGC to 782 DEGC, the working temperature ranging from 920 DEGC to 1200 DEGC and the density ranging from, 2.32 g / cm<3> to 2.5g / cm<3>, which meet the requirement on medicinal packing and reduces the production cost.

The invention belongs to the technical field of printing, and in particular relates to an all-aqueous ink and a preparation method thereof. The present invention adopts hydroxyethyl methacrylate, glycidyl methacrylate, styrene and alginic acid as raw materials to prepare a water-soluble grinding resin solution for quaternary copolymerization to form a base material with stable performance; The all-water-based ink prepared with solvent and water has good fluidity, high color concentration, and good printability; the printed matter has high gloss, good leveling, adhesion fastness and resistance comparable to solvent ink, and no harmful substances remain after drying . Prints are anti-blocking, anti-migration, abrasion-resistant and water-resistant. It can be used for surface printing of shopping bags, medical packaging, transfer bags and food bags printed on the surface of BOPP, PET, PE / PEVA and other plastic substrates.

A tray provided with a limiting structure is used for holding Open Cell of a liquid crystal screen, and comprises: a tray main body (10), provided with a slot (11) for receiving Open Cell; the tray further comprises a clamping part (30), formed of a fastening component (31) connected to the main body (10) and a clamping component (32) movably connected to the fastening component (31). The clamping part (30) and the tray main body (10) stick to one another, and can be assembled or disassembled as required, thereby improving compatibility in use of the tray. In addition, before Open Cell is taken down, the clamping component (32) is raised with respect to a hinged shaft (33), and in this case, a PCB and a Chip on Film (COF) are in a relatively open state, so no external factor hinders Open Cell during use and the COF is protected from being damaged.

A tray with a limit structure is used for packaging an Open Cell of a liquid crystal screen, and comprises a tray body (10) and a limit assembly (30). A groove (11) for placing the Open Cell is disposed in the tray body (10). The limit assembly (30) is connected to a body bottom plate (12) of a gap between a PCB (23) of the Open Cell and a liquid crystal box (22). The limit assembly can be mounted on the tray body when the limit assembly is needed, or can be taken down when the limit assembly is not needed, thereby expanding the use compatibility of the tray. In addition, a position of a limit block in the limit assembly is adjustable, thereby effectively avoiding pull between the Open Cell and the limit assembly.

The invention provides an aluminum-free anti-counterfeiting lining paper for cigarettes and a production method thereof. The lining paper is composed of an anti-counterfeiting paper layer, a coating layer and an aqueous printing oil layer. The technical indexes are as follows: the fixed quantify is 60+ / -3 g / m<2>; the thickness is 0.07+ / -0.005 mm; the flatness is more than or equal to 80 S; the tensile strength is more than or equal to 1.8 kN / m; the whiteness is more than or equal to 80%; the water content is 4-6%; and the air permeability is less than or equal to 0.01 micron / Pa.s. The production method comprises the following steps of: firstly preparing a coating; and then, coating the prepared coating on front and back sides of anti-counterfeiting paper on a coating machine, so as to prepare a product. According to the production method, the anti-counterfeiting paper is used as basic paper and an anti-counterfeiting function is organically combined with the lining paper for the cigarettes, thereby achieving the anti-counterfeiting effect and greatly reducing the cost. The formula of the coating used in the preparation method is unique and a main paint part is papermaking porcelain clay which is widely applied to the papermaking industry and is low in price and an adhesive is polyvinyl alcohol and has no extraneous odor or toxicity; in the production process, no organic solvent is used and no pollutant is generated, thereby protecting environment. Non-ferrous metal such as aluminum foils, aluminum powder and copper powder, is not used, so that the product cost is low, the energy consumption is low, and ideals of energy saving and environmental protection and low-carbon lifestyle are realized.

The invention discloses a peeling device for grain production, a peeling device for grain production, comprising a grain inlet, a box cover, a peeling device, a guide rod, a motor, a drying plate, a water guide, a drying device, and a grain outlet , a controller, a base, an air dryer, a buckle and a card slot, the lower surface of the grain inlet is provided with an adjusting opening device, the box cover is installed under the adjusting opening device, and the lower surface of the box cover is connected with a box body, The peeling device is installed inside the box, the outer surface of the box is fixedly connected with a grain skin outlet, the lower end of the grain skin outlet is provided with a groove, the guide rod is arranged on the outer surface of the box, and the motor is fixed It is connected to the outer surface of the guide rod, and the bottom end of the motor is inserted and connected with bolts. The peeling device for grain production is equipped with a centrifugal peeling device, and the centrifugal device is used to separate the grain from the skin. Compared with the traditional grain peeling device, the effect is better, the grain peeling rate is improved, and the grain is avoided. Broken condition.
