The invention discloses a high-surface-quality hot-galvanized transformation induced plasticity (TRIP) steel plate and a manufacturing method thereof. The hot-galvanized TRIP steel plate is prepared from chemical components in percentage by weight as follows: 0.10%-0.15% of C, 1.20%-1.80% of Mn, less than or equal to 0.030% of P, less than or equal to 0.030% of S, 1.20%-2.40% of Als and the balance of Fe and inevitable impurities. The manufacturing method of the TRIP steel plate comprises the steps as follows: continuous casting steelmaking-hot rolling-cold rolling-continuous annealing and hot galvanizing. The structure form of the hot-galvanized TRIP steel plate prepared with the method includes ferrite, bainite, retained austenite and martensite, the grain size grade ranges from Grade 10.5 to Grade 11, the tensile strength ranges from 640 MPa to 670 MPa, the yield strength ranges from 395 MPa to 465 MPa, the ductility is higher than or equal to 30%, the strength and ductility product can be 23GPa% or above, and the plate has the high surface quality, mechanical performance and corrosion resistance.

The present invention relates to polyoxyethylene-polyoxypropylene (POE-POP) vitamin E, which is prepared from vitamin E by polyethoxylation and polypropoxylation, and a method for preparing the same. The POE-POP vitamin E has a high surface activity and an excellent safety for the skin, so that the POE-POP vitamin E can be advantageously used in the cosmetic industry, the food industry and the medical industry.

The invention relates to a fluorocarbon surfactant and a preparation method thereof, which reacts 10-50 parts by weight of perfluoroalkyl sulfonyl fluoride, 5-45 parts by weight of amine and 20-25 parts by weight of solvent at the temperature of ranging from 20 DEG C to 110 DEG C for 2 through 12 hours to acquire an intermediate product; mixing well the intermediate product with 10-30 parts by weight of an oxidant and stirring the mixture for reaction at the temperature of ranging from 20 DEG C to 80 DEG C for a plurality of hours; adding 0.1-2.5 parts by weight of an accessory ingredient and mixing well after the reaction is finished; in this way, the product is acquired when the filtrated product is stirred and mixed with 5-30 parts by weight of a de-ionized water at the temperature of ranging from 0 DEG C to 50 DEG C. Compared with the prior art, the product prepared by the invention is of short technical process of preparation, simple operation, high reaction efficiency, low production cost and is characterized by high surface activity, high thermal stability and high chemical stability. The surface tension of a water solution of 0.01 percent is lower than 16dyn/m, and the CMC value is lower.

An ultra-high molecular weight polyethylene bulletproof insertion plate of a function laminated structure comprises the following four layers of structures, and the four layers of structures sequentially comprise an outer protective layer, a bullet-resisting deceleration layer, an energy absorbing layer and a deformation restraining layer from outside to inside. The outer protective layer is madeof a waterproof sun-proof material and used for protecting the inner bullet-proof insertion plate structure. The bullet-resisting deceleration layer is made of high-surface-density nonwoven cloth anda thermosetting resin matrix through the mold pressing technology. The thermosetting resin matrix is manufactured through three-dimensional grid hot-pressing technology and forms a three-dimensional grid structure. The energy absorbing layer is made of low-surface-density nonwoven cloth and thermosetting resin matrix through the mold pressing technology. The deformation resisting layer is made ofhigh-surface-density nonwoven cloth and a thermosetting resin matrix through the mold pressing technology. On the premise of the same bulletproof effect, the ultra-high molecular weight polyethylene bulletproof insertion plate of the function laminated structure utilizes less bulletproof fiber, and the obtained insertion plate is lighter, low in manufacturing cost and excellent in protective performance.
