The invention provides an aluminum or aluminum alloy surface nanoscale treatment process. The aluminum or aluminum alloy surface nanoscale treatment process includes the following steps that firstly, aluminum or aluminum alloy is placed in a sulfuric acid solution with the 190 g/L concentration, temperature is kept at 18-22 DEG C, voltage is kept at 17.5 V, and oxidation is conducted for 12-15 minutes; secondly, washing is conducted twice; thirdly, the aluminum or aluminum alloy is placed in a stain remover with the 160 ml/L concentration and the 9-11 PH and immersed for 5-7 minutes at normal temperature; fourthly, washing is conducted twice; fifthly, the aluminum or aluminum alloy is placed in a pore-expanding agent with the 400 ml/l concentration and the 9-11 PH and immersed for 5-7 minutes at normal temperature; sixthly, washing is conducted twice; seventhly, the aluminum or aluminum alloy is placed in a binding agent with the 300 ml/L concentration and the 9-11 PH and immersed for 5-7 minutes at normal temperature; eighthly, washing is conducted twice; and ninthly, the aluminum or aluminum alloy is dried for 10 minutes at the temperature of 65 DEG C. Surface pores of the prepared aluminum or aluminum alloy are uniform, and excellent micro-pore-expanding property and strong viscosity are achieved. When the aluminum or aluminum alloy prepared through the process is subjected to a next injection molding procedure, the binding force of the aluminum or aluminum alloy and plastic particles is extremely strong, firmness is greatly improved, and the drawing force is strong.

Wash-durable face mask with antimicrobial properties and/or improved washability

InactiveCN109862798AReduce high filtration efficiencyReduce filtration efficiencyBiocideCosmetic preparationsParticulatesEngineering
The present invention is directed to a face mask comprising a multi-layer filter material. One or more antimicrobial and/or hydrophilic and/or stain release agents are adhered to a textile material that forms the outer layers of the multi-layerfilter material. The agent(s) is/are adhered to the textile material in such a manner that they are not released from the textile material even if the facemask is washed, so that the face mask as such is re-usable. The particular arrangement of textile layers of the face mask according to the present invention also allows that the face mask can be washed. That is, the textile and the overall structure of the face mask is preserved albeit the physical stress applied during washing. In preferred embodiments, where one or more antimicrobial agents areadhered to the textile material, the face mask can be used to protect the wearer against airborne particulate and microbial pollution, and, in particular, sanitize the inhaled air. Likewise, the environment, such as other persons, are protected from particles and microbes that are exhaled by the wearer of a face mask according to the present invention. Washability and/or usability of the textile material within the multi-layerfilter material of the face mask is/are improved when one or more hydrophilic and/or stain release agents are adhered to the textile material, which is particularly advantageous to ensure that the face mask is rendered as clean as possible during wash, i.e. that absorbed or adsorbed stains are released from the textile. The invention further relates to a method of finishing a textile material by applying and binding antimicrobial and/or hydrophilic and/or stain release agents to the textile material so that the agents are essentially irreversibly adhered to the finished textile material.

Pipeline stain remover

The invention provides a pipeline stain remover, which consists of a first sealing leather cup, a second sealing leather cup, a third sealing leather cup, a stain removing wheel and a first elastic shaft, or a second elastic shaft, or a third elastic shaft, or a fourth elastic shaft, or a fifth elastic shaft, or a seventh elastic shaft. Compared with the prior art, the pipeline strain remover has the advantages that when the pipeline strain remover passes through a pipeline elbow, the self elastic shaft can naturally bend to turn along with the elbow, and after the pipeline strain remover passes through the pipeline elbow, through the self memory function, the working of immediately doing parallel movement to the pipeline axial line is realized, so that the undamaged completeness and the normal operation of the pipeline stain remover are protected, the service life of the pipeline stain remover is greatly prolonged, meanwhile, the pipeline stain remover is positioned at the elbow turning part, the pipeline stain remover can maintain the original state, the sealing performance is good, the air leakage is avoided, the resources are saved, the operation speed of the pipeline stain remover is uniform, the service life of the pipeline stain remover is prolonged, the scale removing cleaning efficiency is greatly improved, and the integral benefits are very obvious.
