Preparation method for antibacterial hydrophobic tipping paper

The invention specifically relates to a preparation method for antibacterial hydrophobic tipping paper, belonging to the technical field of preparation of cigarette materials. The preparation method for the antibacterial hydrophobic tipping paper comprises the following steps: with modified starch as a bridge, separately bonding the modified starch with modified acidified nanometer titanium dioxide, self-made silver-carrying zeolite and self-made ground pulp; and preparing the antibacterial hydrophobic tipping paper under the action of calcium carbonate and polyvinyl alcohol. According to theinvention, chloropropylene oxide and succinic anhydride are used for modification of starch so as to improve the water resistance of the tipping paper; then nanometer titanium dioxide is subjected tocalcining and acidolysis so as to form acidified nanometer titanium dioxide, so the antibacterial properties of the tipping paper are enhanced; a silver nitrate solution is used for modification of zeolite with a porous structure, so the antibacterial properties of the tipping paper are further enhanced; and then the modified acidified nanometer titanium dioxide is mixed with the self-made silver-carrying zeolite, and ester groups are grafted onto the surface of the mixture under the action of microbes to endow the mixture with waterproof capability, so the tipping paper is further improved inwater resistance. The prepared tipping paper has good application prospects.

Preparation method of anti-cracking type waterproof gypsum board

InactiveCN107572995AInhibits the propagation of cracksImprove mechanical propertiesParaffin oilsWollastonite
The invention discloses a preparation method of anti-cracking type waterproof gypsum board, and belongs to the technical field of preparation of boards. The preparation method is characterized in thatpolyethylene glycol stearate is used for modifying self-prepared wollastonite raw fibers, the wollastonite is drawn into wollastonite with a fiber-shaped structure, the starch is subject to double modifying by epichlorohydrin and succinic anhydride when the wollastonite is stirred and added into a gypsum matrix, a board core and a board body form an interface with certain strength, and the hydrophobicity of the starch is realized by hydroxyl substitution in the etherification process; because the crosslinking density in the starch structure is increased, the absorbing of water is also limitedby crosslinking treatment; montmorillonoid and fly ash are added into the gypsum powder, a water-resistant hydration product is generated in the gypsum hydration process, the porosity of the gypsum powder is reduced, and the hole diameter is reduced; paraffin and polyethylene glycol are added, the paraffin is emulsified and then uniformly mixed with a gypsum frame, waterproof agents of sodium trimethylsilanolate and calcium oxalate are coated to the surface of the self-prepared gypsum board blank, and then the waterproof property of the gypsum board is further improved.

Transmission-type prepositive optical path structure used for ICP spectrometer and having two-dimensional adjustable function

The invention provides a transmission-type prepositive optical path structure used for an ICP spectrometer and having a two-dimensional adjustable function, belonging to the technical field of beam splitting systems for the ICP spectrometer. The transmission-type prepositive optical path structure comprises a front optical barrel, a lens fixing base, a sealing ring, an adjusting base, a thread sleeve, a screw, a back lens barrel, an adjusting ring, a spring, a lifting pin, a lock nut, a slip ring, a lens basic ring and a lens pressing ring. Through two-dimensional adjusting of a prepositive lens, changes of the value of detected signals received by a detector are monitored in real time; and when the signal of the detector reaches a maximum extent, it may be considered that the central hole of the lens and the center of an incident pin hole are of same height and are coaxial, and luminous flux of an echelle grating spectrometer is maximized at the time, so optimal analysis capability of the ICP spectrometer is guaranteed. Meanwhile, as six air vent holes are arranged in the adjusting ring, air in an optical chamber is discharged while argon is introduced into a beam splitting system, so absorption of ultraviolet bands by air is restricted, detection limits of ultraviolet bands are lowered, and the application scope of the ICP spectrometer is further broadened.
