The invention discloses a native wood pulp paperboard, which is formed by compounding three layers of paper, which are a surface layer, a core layer and a bottom layer respectively, wherein the used raw materials are unbleached native natural wood pulp fibers; and the native wood pulp paperboard comprises a repulping and grinding procedure; a color and luster control procedure; a fourdrinier wire and top wire forming procedure; a shoe pressing procedure; a sizing procedure; a drying procedure; a hot-roller soft calendaring procedure; and a slitting and rewinding procedure. Through mutual cooperation of the fourdrinier wire and top wire forming procedure, a starch spraying procedure and the hot-roller soft calendaring procedure, the application effect that a non-coating process can also meet the printing adaptability is achieved; through application of the native natural wood pulp fibers and improvement of sheet-making, sizing and calendaring processes, harmful substances introduced by the bleaching and coating processes are eliminated; the native wood pulp paperboard completely meets the food grade requirements; the health and safety indicators are improved; the pressure of environmental pollution is reduced; and the cost is greatly reduced in comparison with that of a coated cardboard.

The invention discloses a hemodialyzer with a polypropylene material outer shell and a manufacturing method thereof, and relates to the field of hemodialysis. The hemodialyzer comprises an outer shell body and membrane fibers. The outer shell body comprises an end cover and a tubular body, and the outer shell body is made of polypropylene. A welding bulge loop which is matched with the end face of the body is arranged at the position, opposite to the end face of the tubular body, of the end cover. The welding bulge loop of the end cover and the tubular body are welded together through ultrasonic waves. The manufacturing method of the hemodialyzer with the polypropylene material outer shell includes the steps that injection molding, pre-assembling, sintering, centrifugal can sealing and cropping of the end cover and the tubular body are conducted, the end cover is fixedly mounted on the tubular body, and leak hunting, drying and assembling are carried out on a dust cap. Plasma activating treatment is conducted on the end cover and the tubular body. The outer shell body is not poisonous, using is safe, the cost of raw materials is low, the molding cycle is short, and the preparation efficiency is high. The manufacturing method saves time and labor, improves efficiency, lowers manufacturing cost, and prevents a sealing ring from releasing substances harmful to the health of people when the end cover and the tubular body are in ultrasonic welding.

The invention relates to non-fried instant noodles with low oil content and fried flavor and a preparation method thereof. The preparation method comprises the steps of kneading a dough prepared from wheat flour, starch, water chestnut flour, raw peanut pulp, a mixed thickener, salt and an edible emulsifier, carrying out the conventional procedures such as boiling, rolling, shredding, cooking, cutting off and folding, subjecting the obtained cooked noodle lump to circulating hot air drying at 100-140 DEG C until the water content is not more than 12%, then uniformly spraying mist-like edible oil on the cooked noodle lump, then carrying out microwave drying and shaping, adding seasoning packets after cooling and packaging the finished product. The preparation method has the advantages that the instant noodles have high nutritive value; the oil content of the pastry is controlled; and the reconstitution property, taste and flavor of the fried instant noodles are maintained.

A vehicle inner decoration package support guard board substrate material and manufacturing technology thereof are disclosed. The substrate material is composed of polypropylene fibers, fibrilia and polyester fibres. The manufacturing technology include: making a synthetic fabric felt; putting the synthetic fabric felt into an open-type oil heating mold; heating it in the mold; taking out the fabric felt in the melted state and putting it in the mold on the hydraulic machine; maintaining the fabric felt in the mold on the hydraulic machine for 2.5-3.5 minutes; and taking out the molding substrate. The invention has advantages that: the backbone material adopts environment protection material, avoids deleterious substance; the present material improves the heat resisting temperature ( 130 EDG C ) of the material based on the original technique PP+ fibrilia series scheme, which satisfy the requirement of the vehicle package support guard board material; at the present, the present material overpasses the consent of the Germany Audi company corporation, which embodies on the vehicle type Audi A6L.

The invention discloses an on-vehicle fully-automatic tea making traveling cup, which comprises an outer cup and an inner cup which is placed on the upper part of the outer cup, wherein the upper end of the inner cup open, while the lower end is sealed and the bottom is provided with a metering hole with a certain size. The vehicle fully-automatic tea making traveling cup also comprises a lower filter screen, an upper filter screen, a tea chamber, a tea water chamber and a tea water channel, wherein the lower filter screen is arranged on the upper part of the metering hole; the upper filter screen is positioned in the inner cup and arranged above the lower filter screen; the tea chamber is positioned between the upper filter screen and the bottom of the inner cup; the tea water chamber is positioned in a space below the metering hole of the outer cup; and the tea water channel is positioned between the inner wall of the outer cup and the outer wall of the inner cup, and is communicated with the tea water chamber directly. The vehicle fully-automatic tea making traveling cup ensures that the tea and the tea water are classified, thereby preventing the problem that the tea water which is placed for a long time can generate hazardous substances. The arrangement of the upper filter screen prevents that the tea in the inner cup enters the tea water chamber when water overflows from the inner cup during making tea. At the same time, the problem that tea powder is easy to enter the tea water chamber or the mouth when the outer cup is inclined for a certain angle or during drinking the tea water is also solved, and the concentration of the tea water is controlled. A user can hold the outer cup for drinking the tea water when drinking the tea water and the tea water can be drunk in all directions so as to be convenient to drink.

The invention discloses a halogen-free flame-retardant ABS / PET alloy and a preparation method thereof. The alloy consists of the following components in percentage by weight: 15 to 50 percent of PET resin, 30 to 60 percent of ABS resin, 5 to 15 percent of phosphorus flame retardants, 5 to 10 percent of nitrogenated flame retardants, 0 to 6 percent of compatilizer, 0 to 5 percent of flexibilizer and 0 to 0.5 percent of antioxidant. The alloy avoids releasing harmful substances to human body in a combustion process of brominated flame retardants by combining a flame-retardant system by adoptingphosphorus and nitrogen compounds, has environmental-friendly significance, simultaneously improves combination properties of a composite material and is easy to mold and process.

The invention discloses a manufacturing method for fibrosis betel nuts. The method comprises the following steps of fresh fruit de-enzyming and fiber solidification, segmentation and nucleus removing, fruit fiber finishing, fruit fiber curing and softening, fruit fiber cooking and tasting, filling and forming, taste determining, and baking and dehydration. According to the manufacturing method for fibrosis betel nuts, fresh betel nuts are used as processing raw materials; on the condition that no additives are added, the fiber softening degree of betel nut processed products is effectively controlled, the production technology process is shortened, the production efficiency is greatly improved, and the production cost is lowered; on the condition that brine is not used, the taste of an original betel nut product is reserved, materials such as quick lime and ephedrine harmful to the human body are prevented from being used, the obtained fibrosis betel nuts are high in nutritional ingredient content, have the healthcare function, are low in hardness and have the rich taste layers, oral cavity injuries are not caused, chronic oral diseases such as oral mucosa fibrotic lesions are reduced, and the fibrosis betel nuts are the betel nut product suitable for being eaten by all crowds.
