A Venetian blinds with magnetic controller for regulation consists of strings which form ladder (11) which hold the horizontally fitted slats (12) at the appropriate distance. This structure hangs on the freely rotating bearing hollow pipe (4), and at the bottom it is connected to the inner bottom section (7). Each magnet (8b) in the bearings (8) or the inner top / bottom contact magnets (8a; 18 a) are fitted to be in the opposite magnet pole in relation to the poles of the external top / bottom contact magnets (18; 18b) on the external top and bottom regulating batten (5; 6) Magnets which glide horizontally along the external top regulating batten (5) attract magnets fitted at the edges of the freely rotating bearing hollow pipe (4). The rotation controller (23a; 23b) enables rotation of the slats (12) for 180 DEG . By moving the bottom / top external regulating batten (6; 5) together with the related magnets it is possible to move the Venetian blind up or down, including moving of only one side of the top / bottom regulating batten (6;5). Therefore, interaction of the mentioned elements of the invention it is possible to shade any part of the window, including shading diagonally along the window, which will be described in detail later.

The invention discloses a preparation method of a super-tough bio-based polyurethane composite material. Carry out according to the following steps: a. modify the purified waste oil with peracetic acid and ethylene glycol in turn to obtain alcoholized oil; b. fully dissolve the toughening agent in a volatile organic solvent to obtain a toughening agent solution; c. Mix alcoholized oil and silicone, place in an oil bath for magnetic stirring, then add toughening agent solution until the organic solvent is completely volatilized, then add crosslinking agent to continue the reaction; after the reaction is completed, the product is solidified to obtain the product. The present invention breaks through the limitation of the traditional single modification on the performance improvement of the polyurethane material, overcomes the pollution of the product by the solvent, the difficulty of material degradation, etc., and realizes the improvement of multiple properties of the polyurethane material. At the same time, by regulating the internal mosaic structure of the polyurethane composite material, A "green" super-tough polyurethane composite material with excellent comprehensive performance is prepared, and a method for preparing a composite material that is environmentally friendly, multifunctional and easy for industrial production is provided.

The invention discloses helical carbon fiber composite ceramic for water activation. The helical carbon fiber composite ceramic comprises a ceramic phase and helical carbon fibers, wherein the helical carbon fibers are distributed and loaded on the ceramic phase. By using the helical carbon fibers, the harmful substance fluctuation can be changed to be fluctuation matched with human bodies. To be specific, sub-micron helical carbon fibers and the ceramic raw material are compounded and then subjected to oxygen insulation sintering, so as to obtain the composite ceramic. The composite ceramic can change the fluctuation harmful to the human bodies and generated by multiple chemical substances, element chlorine, harmful bacteria and the like into fluctuation beneficial to bodies, and enables water molecules to be subjected to declension vibration activation, so that water molecules are changed into smaller molecular clusters and the blood flow volume of human brains is increased obviously; in addition, through the special fluctuation, the effect of inhibiting bacterium reproduction is realized. On the basis of a fluctuation effect, all needed is to add a small amount of the helical carbon fiber composite ceramic, and thus the water quality can be changed instantly. In a water activation treatment process, pollutants are not adsorbed, and chemical changes do not occur, so that later cleaning and maintenance are not required and the helical carbon fiber composite ceramic disclosed by the invention can be used for a long time.
