摘要:
A gradient-gauge applicable on golf green comprises a main body and a bulb level. The main body made of a transparent material is provided thereon a pair of horizontal line and perpendicular line, and its one side is parallel with a straight edge of the horizontal line. A pointer is pivotally jointed at the intersection of the horizontal line and the perpendicular line. The bulb level, which is disposed on the main body, is curved and drawn with angle graduations, in which the bulb of the bulb level is in a position corresponding to the perpendicular line in case the main body is laid in a horizontal plane.
摘要:
A method of coating a photo-catalysis on a surface of a coated substrate, the method comprising the steps of: cleaning the surface of the coated substrate; measuring a temperature near the surface of the coated substrate; mixing for a water content of the colloid solution with TiO2 by a water and the colloid solution with TiO2 to form a mixture and pouring uniformly the mixture into a can of an airbrush; and spraying the colloid solution with the TiO2on the surface of the coated substrate by a shape of micro-foam for decomposing the harmful substances in air as an anti-bacterial, a de-ordorization and an anti-mold function.
摘要:
The present invention relates to a method for increasing the heat-resistant of ethylene-vinyl alcohol copolymer (EVOH), the method is characterized by using a mixture of acetic acid, magnesium dihydrogen phosphate, and potassium dihydrogen phosphate at a certain ratio as an acid-treating solution in the acid-treating procedure of a process for preparing EVOH. The EVOH produced by the method of the present invention exhibits an excellent heat-resistance and does not become yellowing attributed to the elevated processing temperature. Also, the EVOH generated by the method of the present invention exhibits a uniform heat-resistance since the additives are dispersed evenly in the EVOH.
摘要:
A process for continuously preparing ethylene-vinyl acetate (EVAc) copolymer, by subjecting ethylene and vinyl acetate to a solution polymerization by introducing the gaseous phase of the polymerization reaction into an impurity scrubbing column and washing the gas phase with a solvent used in the reaction, then recycling it into the reaction system, thereby impurity generated in the reaction will be removed. A reactive system having a reaction tank for co-polymerizing ethylene with vinyl acetate, an ethylene recovering tower connected with the bottom of the reaction tank, a line connecting with the bottom of the recovering tower for recovering ethylene-vinyl acetate copolymer; and an impurity scrubbing column connecting with the top of the reaction tank for removing impurity generated in the polymerization reaction.
摘要:
This invention concerns a test apparatus and procedure used for quantitative and qualitative characterization of scratch and mar behavior of films or coatings, more particularly automotive coatings. The apparatus includes a micro-indentor that penetrates and scratches the coating to be characterized together with interrelated components for measuring the force applied, the length and depth of the indentor penetration, the geometry of the disturbed coating surface as well as a system for measuring, analyzing and comparing test results.
