3 General Test
Reagents and instruments, sample preparation, test procedures and test reports according to GB/T 2910.1 regulations. Test methods as described above Regulation
Given different, are listed in the specific test method. The solution used in (%) is taken to mean mass fraction.
Test Method 4
4.1 two-component mixture of metal fibers and cellulosic fibers (75% sulfuric acid method)
4.1.1 Principle
With a sulfuric acid solution to cellulose fibers from a known dry mass of the mixture is dissolved and removed, the residue was collected, washed, dried and weighed, with
The quality of the revised calculation of its share percentage of the dry mass of the mixture. Derived from the difference between the percentage of cellulose fiber quality.
4.1.2 Reagents
Use GB/T 2910.1 and 4.1.2.1,4.1.2.2,4.1.2.3 provisions reagents.
4.1.2.1 75% sulfuric acid solution. Measure 700mL of concentrated sulfuric acid (ρ = 1.84g/mL) was carefully added to 350mL water, and the solution was cooled to
Room temperature, add water to 1L. Concentration of sulfuric acid in the range of permitted between 73% ~ 77% (ρ = 1.65g/mL ~ 1.69g/mL).
4.1.2.2 50% sulfuric acid solution. Measure 400mL of concentrated sulfuric acid (ρ = 1.84g/mL) was carefully added to 500mL water, and the solution was cooled to
Room temperature, add water to 1L.
4.1.2.3 dilute ammonia solution. concentrated aqueous ammonia 80mL measure (ρ = 0.88g/mL), diluted with water to 1L.
4.1.3 Test procedure
According to GB/T 2910.1 prescribed generic procedure, and then follow the steps below.
The prepared sample was placed in a stoppered Erlenmeyer flask, per gram of sample was added 150mL75% sulfuric acid solution (4.1.2.1), shake flask
