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.
