Problems solved by technology

[0002] At present, in the field of natural rubber measurement and analysis, the determination of the total solid content in latex requires more accurate oven drying, but this method is time-consuming (8-12 hours), power-consuming, and cumbersome to operate. Only suitable for measuring a small number of samples
For a long time, it has been difficult for technicians in this field to find a so-called ideal rapid total solids content determination method that is fast, easy to operate, strong in anti-interference, and the accuracy is closest to the standard oven drying method.

Embodiment 1

[0029] Example 1: Operation method

[0030] 1. Use a disposable syringe to drop a small amount of latex sample into a numbered container of rated weight (including foam metal with a weight of ω 0 ), weigh the total weight ω of the sample and the vessel 1 , prepare several samples to be determined according to this method;

[0031] 2. Place the prepared vessel on the heat source in the vacuum system, turn on the vacuum switch, and make the system reach a negative pressure state.

[0032] 3. Use the temperature controller to set the heating temperature to 180-350°C, set a few minutes, and vacuum dry the sample;

[0033] 4. Weigh and measure the dried sample together with the vessel to obtain the weight ω 2 ;Use the following formula to calculate the total solid content α of the sample:

[0034] .

Embodiment 2

[0036] A kind of measuring equipment of the total solid content of natural rubber latex, comprise the metal container 6 that is made of metal foam of rated weight, the electric heating plate 5 of heating metal container 6, described measuring equipment also includes the described metal container 6. A sealed box 1 for vacuuming. The measuring equipment also includes temperature, vacuum and other function control knobs 3. The temperature, vacuum and other function control knobs 3 control the electric heating plate 5 and the vacuum pump 2. Control, the measuring device also includes a plate weighing system 4, and the measuring device also includes a digital display 7. The metal foam is covered with metal foil 8 on its side and bottom.

[0037]

Embodiment 3

[0039] The samples were fresh natural rubber latex purchased from the purchase point of the rubber factory on the same day.

[0040] 1. Determination of total solids content by standard oven drying method: use a disposable syringe to take 2 to 3 grams of latex for determination, drying temperature is 70 ° C, time is 10 hours, and three groups of sample tests are done;

[0041] ω 0 : vessel weight;

[0042] ω 1 : The total weight of the container and latex before measurement;

[0043] ω2 : The total weight of the container and latex after drying;

[0044]

[0045] 2. Determination of total solids content by vacuum drying method (using the method of Example 1 and the equipment of Example 2): use a disposable syringe, take 0.2 to 2 grams of latex for measurement, drying temperature 200 ° C, vacuum degree -0.09 Mpa, time 3 minutes, do three sets of sample tests;

[0046] ω 0 : vessel weight;

[0047] ω 1 : The total weight of the container and latex before measurement; ...

Description

technical field [0001] The invention relates to the technical field of natural rubber, in particular to a method and equipment for measuring the total solid content of natural rubber latex. Background technique [0002] At present, in the field of natural rubber measurement and analysis, the determination of the total solid content in latex requires more accurate oven drying, but this method is time-consuming (8-12 hours), power-consuming, and cumbersome to operate. Only suitable for measuring small samples. For a long time, it has been difficult for those skilled in the art to find a so-called ideal rapid total solids content determination method that is fast, easy to operate, strong in anti-interference, and the accuracy is closest to the standard oven drying method. Contents of the invention [0003] The purpose of the present invention is to provide a kind of assay method of natural rubber latex total solid content, and this method is accurate, fast, easy to operate, ...
