Ink-jet recording material and preparation method thereof as well as method for preparing ink absorption layer coating liquid

The invention provides an ink-jet recording material and a preparation method thereof as well as a method for preparing an ink absorption layer coating liquid, and relates to an ink-jet material and a preparation method thereof as well as a method for preparing an ink absorption layer coating liquid, so that the problems of poor ink absorption effect, nonuniform color distribution of printed images, unclear printed images and higher preparation cost of the existing ink-jet recording material can be solved. The ink-jet recording material is prepared from the ink-jet layer coating liquid which is prepared from PVC (polyvinyl chloride) serving as a base material, a 20-30% polyacrylic acid emulsion serving as a primer, an inorganic nano-pigment with the thickness of 10-100nm, a dispersing agent, acetic acid, deionized water and an adhesive aqueous solution. The prepared ink-jet recording material prepared through PVC material corona treatment, PVC substrate glue coating, drying, ink absorption layer coating and drying has the advantages that that the printed image is clear, the ink droplet does not diffuse, and the color is distributed uniformly; and the ink-jet recording material has excellent performances of color definition, color saturation, glossiness and the like. The raw material cost and the manufacture cost are low, so the ink-jet recording material is advantageous to industrial production, popularization and application.

Nitrite-substituted meat processing method

The invention discloses a nitrite-substituted meat processing method, and belongs to the technical field of food processing. The nitrite-substituted meat processing method comprises the following steps: selecting raw materials, carrying out pickling treatment and processing a meat product, so that the final products of the meat product are prepared; and the nitrite is substituted by a nitrite substitute during the step of carrying out pickling treatment. The nitrite substitute comprises the following components in parts by weight: 4-5 parts of monascorubin, 0.7-1.3 parts of betanin, 4-6 parts of potassium sorbate, 2-3 parts of D-sodium isoascorbate, 1.5-2.5 parts of nisin, 9-11 parts of sodium lactate, 1-2 parts of natamycin, 5-6 parts of natural vitamin E, 1-2 parts of a rosemary extract, 0.5-1.5 parts of sage essential oil, 1-2 parts of tea polyphenols, 15-16 parts of L-sodium glutamate, 0.5-1.5 parts of flavoring 5'-disodium ribonucleotide, 40-43 parts of a yeast extract, 4-5 parts of sodium tripolyphosphate and 0.5-1.5 parts of ethyl maltol. The nitrite-substituted meat processing method disclosed by the invention is simple, easy to operate and free of nitrite addition; and the prepared meat products are very good in qualities, color, luster and taste.

Method for bleaching grey down feather

InactiveCN101705612AThe whiteness is obviously improvedDown damage is smallBleaching apparatusIonChemistry
The invention discloses a method for bleaching grey down feather. The method comprises the following steps: firstly, using ferrous ions to conduct pretreatment on down feather to be treated, then conducting selective oxidation bleaching on the down feather, and finally using thiourea dioxide to conduct reduction bleaching on the down feather, and using clear water to wash the down feather, and drying. The method can effectively eliminate the natural pigment in the down feather, and has less damage to the down feather; the selective oxidation bleaching and reduction bleaching by using the thiourea dioxide (TDO) are combined to treat the down feather; after the TDO is applied to conduct reduction bleaching under the mild condition on the down feather treated by selective oxidation bleaching, thus improving the whiteness of the down feather, leading the decolorization and bleaching of the grey down feather to achieve high-level whiteness, and inhibiting the color reversion of the down feather; and the TDO is an acid reducing agent, can play the role of strong reducing property under the acidulous and neutral conditions, is suitable for the stability condition of the protein fiber in the down feather, and has little damage to the fiber. The whole process for decolorizing and bleaching the down feather is conducted at low temperature, thus not only ensuring the little damage to the fiber, and good bulkiness, but also being beneficial to energy conservation and environmental protection.

Laser engraving method of plastic component

The invention relates to a laser engraving method of a product, in particular to a plastic component laser engraving method for engraving any pattern or mark in an elastic workpiece with one layer being lucent. Laser engraving is carried out inside the plastic component at least comprising one layer of transmission material. The method comprises the following steps of starting a laser engraving machine; measuring the size of the plastic component to be engraved; editing the patterns and characters; calculating points of the patterns; calling in a picture file, selecting product dimensional specification and setting parameters; and carrying out the engraving. Due to the adoption of the laser engraving method of the plastic component, not only can the display effect of the patterns and characters of the traditional process be realized, but also the defects of the traditional process such as paint dropping, dropping, color fading, non-abrasion resistance, short service life, easiness for storing dirt, environmental pollution and incapability of individualized production can be solved; and moreover, a novel high-efficient and environment-friendly technique for producing any pattern and character with no material consumption can be realized, and a broad individualized exhibition platform can be provided for the individualized times.
