Abstract

The invention relates to a titanium dioxide slurry transmittance measurement and test method, comprising the specific steps of (1), connecting a silicone rubber pipe between a pressure control system and a slurry receiver, opening a compressed air valve, and adjusting a pressure gage to 0.3Mpa; (2) slowly pouring titanium dioxide slurry into a wide-mouth hopper until a filter screen is completely blocked; (3) measuring the volume of the filtered solution of the titanium dioxide slurry by using a measuring cylinder; (4) calculating, wherein 1 micrometer of filtration amount is equal to filtration milliliter quantity when the filter screen is completely blocked. The method has the advantages that a device is low in production cost, about 300 Yuan; the structure is simple, the operation is convenient, and the population is easy; faults cannot be generated in a use process, and maintenance charge is basically not needed by cleaning well.

Description

【Technical field】 [0001] The invention relates to the technical field of polyester production testing, in particular to a testing method for measuring the transmittance of titanium dioxide slurry. 【Background technique】 [0002] In the production process of polyester semi-dull chips, it is necessary to add an appropriate amount of ground titanium dioxide to make the fibers obtained after post-processing have a better matting effect. [0003] The grinding effect of titanium dioxide is directly related to the quality of polyester semi-dull chip melt. All production companies have the measurement of titanium dioxide slurry transmittance that reflects the grinding effect of titanium dioxide, but there is no unified detection method standard for the measurement of this item at present, and most of the measurement equipment are self-made, and the repeatability of the measurement results obtained is poor , and the size of the measurement results of various enterprises is very diff...
