Some standard content:
CB/18723—2002 This standard adopts the international standard S012634926 equivalent to the international standard S012634926 - Testing the properties of plastics and injection molding materials, and basically retains the structure and content of the original international standard, but makes some changes to the rules in the compilation and interpretation to suit the Chinese standard. This standard is mainly issued by the National Printing Standardization Technical Committee of the People's Republic of China. The drafting unit of this standard is Beijing Institute of Printing Technology. The main drafters of this standard are: Xia Lin, Qi Xiaodian, He Xiaohui. 18: CB/T18723:2002 ISO Foreword S) The International Organization for Standardization is a world federation of national standardization bodies (member bodies): The formulation of national standards is usually completed through 13 technical committees: each subject is independent. , each member body interested in a particular subject has the right to be represented on that technical committee. All official or unofficial international organizations collaborating with ISO may also participate in this work. In the area of technical standardization, ISO is closely linked to the International Committee for Standardization (IFC). International standard proposals submitted by technical committees must be voted on by member countries: an international standard must be approved by at least 75 of the member countries before it can be formally issued. Technical - Viscosity tester for viscosity of slurry ink and continuous particles, drafted by ISO/TC130 (Industrial Technical Committee), GR/T18723-2002, is a basic parameter for evaluating the viscosity of oils and binders. It can be used to describe the relative quality of the upper surface of the machine: the factors affecting the viscosity value include elastic diameter, hardness and And elastic modulus, line pressure, surface adhesion, lack of rotation speed, potential temperature, ring magic travel skin, sample scheduling film thickness, oil suspension binder on the elasticity of the report (such as the absorption of the agent!. The condition of the elastic mask during cleaning. Long-term use of the test sample, the nature of the drug, etc. This standard is only a guide, it is not a substitute for the fast technical rules. 15 1 Scope National Standard of the People's Republic of China Printing Technology Viscometer Secretion of Paste Oil and Viscosity of Connectors Craphic tecmology-Peteriminalinn nf tack nt pakte inkrond vehicles by rotary This standard is used as a general method for determining the viscosity of a slurry and its properties. GB/T18723-20J2 eqv[S012634:1996 Long standard road is used to determine the viscosity of a slurry under normal environmental conditions in a low-temperature and non-reactive oil tank. 2 Definitions This standard adopts the following definitions: Viscosity The resistance between two transductions of a given value Oil lift or connect the material film layer with high force. Note: Viscosity is a full-air parameter - it is a combination of the material and chemical properties of the fluid. 3 Test method || tt || 3.1 Cooling || tt || The new instrument points out 3 main parts of the piece, one of which is a single life, the middle is an empty section, with circulating water to adjust the temperature, this saw is driven by a motor to change the 1 dynamic rotation, the British can be withered, for a group of elastic rubber spokes, often self-pressed on the gold roller, the star shows the state of the dry rod connected to the cat, the first: It is a semi-plastic elastic glue. Use a viscosity meter to measure the resistance of the oil or the film layer of the adjacent material to separate, and express it in numbers, that is, the viscosity value: 3.2 Design of skin material 3.2.1 Adhesive section 3.2.2 Accumulator: The value is 11. 3.2.3 Table: The degree is 0 3.2.4 Standard material, 3.2. The instrument is +0 3.2.6 The cleaning agent will not make the corrosive property 3.3 Test conditions The ambient temperature is 2℃: 31±1℃ (· The temperature can be maintained at 31±1℃. 3.4 Viscosity adjustment 3.4.1 After the whole assembly is installed, the elastic stock should be adjusted before testing, until the test data of the sample or injection material shows a constant value: 3.4.2 During normal use, the instrument manufacturer shall be consulted with the manufacturer for the adjustment. It is recommended to use the internal performance marking oiler or injection material as the standard material. 3.4.3 If the material of the test oil or the connecting material is affected (such as the transmission material), the test device should be used. 3.5 Preparation The tested product should be stable and free of any particles. 3.6 Filtration test method 3.6.1 Check the power supply of the instrument and adjust the constant The temperature of the machine is kept constant at 31℃1:C. 3.6.2 Use the injection & ink sample to evenly wash the sample on the elastic rubber, start the motor, make the sample evenly on the machine and the measuring machine, and the injected oil or continuous slurry should meet the requirements recommended by the instrument manufacturer. Note: The manufacturer's previous two types of samples can provide the most continuous quality muscle thickness quality feedback for the heat test results. The next time is a few manufacturers to work with the existing quality, classic, etc., these quality funds are produced from 4T, 13m topic quality sharing to make the viscosity Knt-a Terh 200( I'rifhauIokojnal Pru-knu Tuckoma? Ieck-u-ecupe Thwing Alben IrkoieterwwW.bzxz.Net Toyoseiki lekogt-pa Injection amount (m2) 3.6.3 Start the viscosity meter, and adjust the instrument's wide speed lever to measure the viscosity. Then adjust the balance lever to 2V3 and adjust it to balance. Read the viscosity value at 1nmin. 3.6.4 If necessary, determine the viscosity of the oil at medium speed. Move the instrument's wide speed lever to medium speed or full speed position. The test steps are the same as those at low speed. 3.6.5 If it is necessary to measure the viscosity value of the oil, keep running except for other conditions and continue running. At 15min, take the viscosity value: compare the viscosity value at 15min with the viscosity value at 1min. The value of the property value is taken as the required property value. 3.7 Cleaning After the test, clean the filter and the injector with a cleaning system. 4 Test result report The test result report should include the following: Test details: Viscosity or viscosity value; Room temperature; Thermostat temperature! Viscosity type: Sample roll or plastic thickness of the test sample under the specified condition; Surface temperature, unit, rpm and m/min; Time; Reading time; Record of non-standard conditions: Test period: - Name of the tester.
