0.2) between g, it is respectively put into porcelain crucible, 625 DEG C of 1 h of calcining in Muffle furnace is placed in, to remove the leaching of fiberglass surfacing
Moisten agent, then take out the crucible with sample, put into drier and cool down；
（2）Claim sample：Environment temperature control exists（24±1）DEG C, the quality of the sample after calcining cools down is weighed, is accurate to 0.0001
G, high-strength and high-modulus glass fibre is put into beaker；
（3）Immersion：The hydrochloric acid solution 100ml of 10% ratio is added in beaker, sample exists（24±1）At a temperature of DEG C, immersion 24 is small
When；
（4）Rinse：After 24 hours, the hydrochloric acid of immersion is outwelled, and sample rinsed repeatedly with distilled water, after flushing
Water ph value when reaching 7 untill；
（5）Drying and cooling：The high-strength and high-modulus glass fibre that flushing finishes is put into baking oven, dries 2 h drying with 120 DEG C, it
After put into drier and cool down；
（6）The residual qualities of sample after corroding are weighed, are accurate to 0.0001 g；
（7）Test result calculations：
Calculation formula isR HCl =1-M 1 /M 0
In formula：R HCl -- weight-loss ratio of the sample in 10% hydrochloric acid solution, %；
