Embodiment
[0048] (1) Weigh 2g of titanium dioxide and place it on the lower glass plate cleaned by the automatic grinding machine, absorb 0.7mL of refined linseed oil with a straw and add it, and fully mix the titanium dioxide and refined linseed oil with the tip of a spatula to obtain a slurry shape.
[0049](2) Spread the slurry obtained in step (1) into a strip about 50 mm wide, which is approximately in the middle of the edge of the lower glass plate to the center, and the slurry that is stuck on the spatula as much as possible Wipe on the upper glass plate of the grinder, close the grinder plate, apply a force of about 1KN to grind, 50 revolutions each time, and grind 4 times in total. Collect the material together, spread it into strips with a width of 50 mm, and wipe the spatula on the upper plate; when the grinding is finished, remove the slurry from the plate, store it in a suitable container for later use, and obtain the sample pulp.
[0050] Take another standard sample of ...

Abstract
The invention provides a sample preparation method for a titanium dioxide papermaking application evaluation method, which comprises the following steps of: a) mixing titanium dioxide and refined linseed oil to obtain pulp; and b) spreading the slurry obtained in the step a), and grinding to obtain the sample slurry for the titanium dioxide papermaking application evaluation method. Compared with the prior art, the sample preparation method for the titanium dioxide papermaking application evaluation method provided by the invention only adopts two raw materials of titanium dioxide and refined linseed oil, is simple in sample preparation process, low in labor intensity, short in consumed time and high in working efficiency, and has the advantages of simplicity, high efficiency and high practicability; the sample slurry is prepared and obtained. The method is used for titanium dioxide papermaking application evaluation, the judgment result is good in repeatability and high in reliability, has a consistency relationship with customer characterization trend, and has great significance for production guidance.
Description
technical field [0001] The invention relates to the technical field of titanium dioxide, more specifically, relates to a sample preparation method for the evaluation method of titanium dioxide papermaking application. Background technique [0002] Titanium dioxide is an important inorganic chemical pigment, the main component is titanium dioxide, which has important uses in papermaking, paint, ink, papermaking, plastic rubber, chemical fiber, ceramics and other industries. [0003] At present, the reagents used in the existing evaluation methods for the application of titanium dioxide in papermaking include seven kinds of reagents: desalted water, broad-leaved pulp board, bentonite, titanium dioxide, 0.5% sodium hydroxide, 5% wet strength agent and 10% aluminum sulfate. 100g, 2g, 0.1g, 1.5g, 1.2ml, 2.3ml and 2ml; the specific sample preparation method is as follows: sequentially weigh the reagent desalted water, broad-leaved pulp board, bentonite, titanium dioxide, 0.5% sodi...
