Embodiment 1
[0045] This embodiment provides a method for obtaining the rheological parameter range of wall putty construction, which is characterized in that it includes the following steps:
[0046] S1. Sampling the putty sample and loading the putty sample according to the sampling requirements of the rotational rheometer;
[0047] S2. Rheological test: start the test after putting the putty sample at rest for 2 minutes, collect a number of torque and corresponding rotational speed signals, and calculate and output the shear stress-shear rate data points respectively;
[0048] S3. Perform data processing on the shear stress-shear rate data points obtained in step S2 to obtain rheological parameters of the putty sample, which rheological parameters include yield stress and plastic viscosity;
[0049] S4. Obtain rheological parameters of several putty samples according to steps S1-S3, and select a range of rheological parameters in which the construction performance of the putty meets the...
Embodiment 2
[0066] Embodiment 2 provides a method for obtaining the rheological parameter range of wall putty construction, including: measuring the rheological parameters of several putty samples, and manually scoring the construction performance of each putty sample, according to the scoring value of each putty sample, Determine the range of rheological parameters in which the construction performance of putty is up to standard.
[0067] In the above scheme, the acquisition of the rheological parameter range of the putty construction performance is based on manual scoring, and the accuracy of the rheological parameter range of the putty construction performance can be improved by scoring the putty samples by senior construction personnel, although this method is based on manual scoring. Scoring, but more objectively provides a method of identifying the construction performance of putty, and identifies the construction performance of putty in the form of data (rheological parameters). Ho...
Embodiment 3
[0103] In embodiment three, a specific method for obtaining the range of rheological parameters is provided according to specific examples:
[0104] Step 1. Prepare putty paste samples according to the formula in Table 1.
[0105] The sample preparation method is as follows: first add an appropriate amount of water to the production kettle, slowly add the adhesive while stirring at a constant speed with a dispersing plate, at this time, a large amount of foam appears, and then add other additives such as defoamers in turn, after 15 minutes A homogeneously dispersed liquid is obtained. Slowly add heavy calcium powder, reduce the rotating speed of the dispersing disc and disperse for 15 minutes to obtain a paste-like finished product.
