The method and actually apply that the workability of semisolid decorative material product in building industry professional standard is evaluated
There are great differences for work situation.JG/T 298-2010 inner wall of building putty and JG/T 157-2009 putty for exterior use pair
The description of application property has " having obstacle " or " accessible ", and subjectivity ingredient is big when judging, without digital parameters limit standard.Going out
The true of process is scraped at present or by senior construction personnel to putty batch to the workability evaluation of putty product when factory examines
The method that feel does subjective marking.Although the method can quantify, for quantitative source digital in subjective sensation, score
Height be difficult to directly interrelated with formula composition, need one kind that can be associated with formula, technique and practice of construction performance thus
Objective quantification index, by this quantization index and practice of construction performance be mapped.It is most important when evaluating workability
The feel for being construction personnel during batch scraping.For semisolid decorative material batch scrape the Quantitative study of feel mainly from
Rheologic characteristics of material sets out, using the intrinsic rheological parameter of material as its workability of metrics evaluation.Can by rotational rheometer,
