Description
Technical field
The present invention relates to engineering material field, especially a kind of wall surface putty construction rheological parameter range acquisition methods.
Background technique
Mainly being scraped by batch knife and putty knife by batch by experienced constructor for wall surface putty is applied at present
Work.When developing or improving inner wall putty powder and putty paste product, the formula and technique adjustment of Optimizing construction performance are mainly
Site operation is simulated by experienced constructor, is then scored item by item multiple Construction performance standards.Formula design work
Cheng Shi adjusts formula according to appraisal result.In workability scoring item, criticizing and scraping feel is to determine scoring height
Most important factor.Constructor is influenced very greatly on the appraisal result for scraping feel is criticized by artificial subjective factor, and different people is even same
Individual is likely to occur inconsistent in the appraisal result that different time provides.It is this inconsistent caused because of subjective human factor
Appraisal result uncertainty largely disturbs the development of product formula.It is steady in control factory product quality simultaneously
Qualitative aspect also needs a set of objective reliable criticizing for technical indicator measurement putty product and scrapes feel.
The method and practice of construction situation of the workability evaluation of putty product in building industry professional standard exist very
Big difference.The description of JG/T 298-2010 inner wall of building putty and JG/T 157-2009 putty for exterior use to application property
There is " having obstacle " or " accessible ", subjectivity ingredient is big when judging, without digital parameters limit standard.In exfactory inspection to greasy
The construction hand valuation of sub- product does subjective beat at present or by the true feel that senior construction personnel scrapes process to putty batch
The method divided.Although the method can quantify, for quantitative source digital in subjective sensation, the height of score is difficult to directly
It connects interrelated with formula composition, a kind of objective quantification that can be associated with formula, technique and practice of construction performance is needed to refer to thus
The index of this quantization and practice of construction performance are mapped by mark.When evaluating putty workability, it is most important that constructor
Feel of member during batch scraping.The Quantitative study of feel batch is scraped mainly from rheologic characteristics of material for putty, with

04.7) quality of workability is measured.
Two kinds of standard method of test of consistometer and jumping table are all to investigate material bending since static to the static state before flowing
Take stress, this with practical putty or mortar during batch scraping quickly to sprawl process not fully identical.Putty itself is half
Solid-state has stronger thixotropy.The consistency numerical value that some samples are measured with consistometer is larger, but it is fine batch to scrape feel,
So application consistency value is as single evaluation index, this may cause to mislead to formula adjustment.In addition, both are simple above
The measurement result of instrument is affected by the operator larger, and the comparativity between data that different operation person obtains is poor.
The present invention design feature tiny for surface layer putty filler, by high-precision rotational rheometer, objective anti-
While reflecting putty and batch scrape feel, good repeatability and reproducibility data are obtained, and determined according to mass data and be suitble to match
