The on-line oil coating device comprises an upper cover and a lower cover which are buckled together in a sealed manner, wherein a sealed high-pressure cavity is arranged between the upper cover and the lower cover, and a front squeezing mechanism and a rear squeezing mechanism are arranged in the high-pressure cavity; the high-pressure cavity is provided with an oil feeding nozzle; and the oil feeding nozzle and an oil coating gun are movably arranged together. By the on-line oil coating device, the steel stranded wires can be coated with oil on line; and the oil coating device adopts a high-pressure cavity structure, so that the oil can go deep into slits between wire strands, the oil can be comprehensively coated, and an oil coating effect is good. The oil coating device can be replaced according to a specific situation; and the upper cover and the lower cover of the oil coating device can be movably opened and closed, so that the oil coating device is easy to machine and use. The oil coating gun and the oil feeding nozzle are convenient to dismount because of movable connection; after the oil coating gun and the oil feeding nozzle are mounted, a sealing effect is good; and the front squeezing mechanism and the rear squeezing mechanism have functions of pressing the oil and scraping the oil. The on-line oil coating device is rational in structural design, good in using effect, convenient to maintain and replace and very suitable for popularization and execution.

The invention discloses a quick qualitative and quantitative method for oligosaccharide in breast milk. The quick qualitative and quantitative method mainly includes steps of 1, pretreating samples, to be more specific, removing fat and proteins from 150-250 micro-l of breast milk to obtain ultimate supernatant, adding ultra-pure water into the supernatant and diluting the supernatant to obtain the loaded samples; 2, establishing standard curves for standard substances by the aid of ultrahigh-performance liquid chromatography and mass spectrometry; 3, separating different components of the oligosaccharide in the breast milk in the loaded samples by the aid of ultrahigh-performance liquid mass spectrometry and carrying out quantitative analysis by the aid of mass spectrometry combined with the standard curves so as to obtain the content of the oligosaccharide in the breast milk. The ultrahigh-performance liquid chromatography is implemented by the aid of amino chromatographic columns with the sizes of 2.1*100 mm and 1.7 micrometers, 8-10 mmol / L of ammonium formate solution (A) and acetonitrile (B), and the ammonium formate solution (A) and the acetonitrile (B) are used as mobile phases; gradient elution programs are carried out by the aid of 95%-75% of B for 0-10 min or are carried out by the aid of 75% of B for 10-15 min or are carried out by the aid of 75%-65% of B for 15-20 min or are carried out by the aid of 65%-10% of B for 20-21 min or are carried out by the aid of 10% of B for 21-24 min or are carried out by the aid of 10%-95% of B for 24-25 min or are carried out by the aid of 95% of B for 25-35 min; the flow rates are 0.3 mL / min, and the column temperatures are 40-60 DEG C. The quick qualitative and quantitative method has the advantage that 12 types of oligosaccharide in the breast milk can be quickly detected by the aid of the quick qualitative and quantitative method and can be quantified by the aid of the quick qualitative and quantitative method.

The invention belongs to the field of preparation of CSM (chlorosulfonated polyethylene), and particularly relates to a method for preparing oil-extended CSM through a gas-solid reaction. The method comprises steps as follows: high-Mooney-viscosity CPE (chlorinated polyethylene) powder and an anti-bonding agent are added to a reactor, stirring is started, the inside of the reactor is vacuumized, the reactor is filled with hot nitrogen and then decompressed, the process is repeated for multiple times, an ultraviolet lamp is turned on for irradiation, chlorine and sulfur dioxide mixed gas is fed into the reactor, a reaction product is transferred to purified water to be washed repeatedly until the pH of the washing water is higher than 6 after the reaction, then a material is dehydrated and dried, high-Mooney-viscosity CSM powder is obtained, the high-Mooney-viscosity CSM powder and rubber processing oil are put into a high-speed stirrer in proportion, a stabilizer is heated, mixing and forming are performed by the aid of conventional rubber mixing and forming equipment, and the oil-extended CSM product is obtained. With the adoption of the method, problems that a main raw material, namely, low-Mooney-viscosity CPE, is difficult to produce, the CSM product is not high in tensile strength, the production cost is high and the like in the process for producing the CSM with an existing gas-solid method can be solved.

The invention relates to a composite liposome of bamboo leaf flavonoids, a preparation method and an application thereof. The bamboo leaf flavone composite liposome of the present invention contains the following components in weight ratio, bamboo leaf flavone: compound agent: membrane material: proppant: antioxidant: solubilizer=0.1-2: 0.1-2: 0.2 ‑5: 0.02‑0.5: 0.01‑0.1: 0.1‑2. The invention protects the stability and integrity of its functional components by effectively coating the bamboo leaf flavonoids. In the wrapping process, hyaluronic acid with excellent moisturizing effect is compounded to prepare bamboo leaf flavonoid complex liposome, which improves its system compatibility in the development of skin care products. At the same time, the unique carrying performance and slow-release ability of liposomes can promote the absorption and long-term care of bamboo leaf flavonoid complex liposomes in the skin, and improve the expression of skin moisturizing, sun protection, whitening and anti-aging effects.

The invention discloses a method for tanning sheepskin with an organic amine synergistic epoxy resin composition tanning agent. The softened or acid-removed sheepskin is first treated with an organic amine bath, and then an epoxy resin combination is added. tanning agent. Because the present invention allows the organic amine to penetrate into the leather fiber first, it can cooperate with the epoxy resin tanning agent to react with the amine group of the organic amine and the amine group on the skin collagen fiber at the same time to form a network crosslinked structure, thereby not only improving the leather's durability. Moisture and heat stability, also enable epoxy resin to be used as the main tanning agent to tan sheepskin, improve its tanning performance, and make the tanned sheepskin grain clear, full leather body, white color, excellent yellowing resistance , The storage period of the tanned leather at room temperature is more than 6 months.

The invention discloses an application of a star type polycation based compound as bactericide. A high performance star type poly-quaternary ammonium salt bactericide is synthesized. The bactericide can effectively inhibit hydration, swelling, dispersion and migration of clay even if the using amount of the bactericide is very low. The molecules of the cation bactericide comprise 18 quaternary ammonium salt groups, thus the bactericide can act on the clay particles with negative charges through multiple sites, the adsorption degree is high, the using amount is low, and the swelling inhibitingperformance is excellent. The cation bactericide can be widely used to process oil containing sewage in an oil field.
