In the production process of listed materials and their preparation, the main fibers are used in the field of anti-blood-proof and anti-flying environment. The relevant parts of BS29721269 Test methods for optical and mechanical thermal insulation materials: This standard is drafted by the National Building Materials Association (SA/C191) and the main persons in charge of drafting this standard are: Beijing Glass Fiber Research Institute, Zeng Naiquan and Zhang You. 1 Standard
Test method for oil content in mineral wool and its products GB/T5480.8-2C03
This standard specifies the widely used method for determining the oil content in mineral wool and its products, the test steps, the design and the test safety. This standard is applicable to the determination of the content of binders in wood and its products (with the age of the tree as the standard). 2 Reference documents
: The clauses in this standard are approved as the provisions of the wood standard. All clauses of the use of this standard are not applicable to the wood products of the same age. ·Only with all the revised drafts (excluding the abandoned or damaged versions) that are not close to the standard, however, the various specifications reached according to this standard are allowed to use the latest version of the document. All documents without a reference date are applicable to the latest version of the technical standard, GBT=1321995 Insulation material name consultation technical certificate
3 Terms and meanings
GH/T=1321995 and the following technical certificates and definitions determined are applicable to this standard. ecnlent
The mass of the cloth and cotton and the large-scale dust-proof oil measured under the specified conditions is expressed as a percentage of the value of the dust-proof oil.
4 Principle
Use a special agent to extract the oil from the expanded material and its products. Take the liquid and separate it carefully. After the high-quality oil is separated, the oil content of the expanded material and its products will be determined by the quality of the oil. 5 Apparatus

Randomly select 3 samples from the sample (rock country , slag book each minus 1 sample 0.58, glass each test? Work 3.5. Change: 055 drum with ten drop box in the can ten 23. Move ten dry antelope to the room plate: 6.1 you measure the dry test selection. New accuracy.

The correct amount of environment: the installation flow rate to take the hope of dangerous spots, red I harm the stem joint device by "constant temperature hole Yu, reverse continuous lifting, 1, seek to take the rate should be controlled in the reflux red tube every hour national flow 1 paragraph || tt || 6.3 will be collected this partial calcium through the method. And a small amount of concave point rise 6.4 Place the flask, cooling tube and bottle in the steaming flask (see figure). 6.5 Add the required equipment under the specified conditions to make the benzene evaporate and condense back into the steamer. 6.6 When only a small amount of liquid is left in the steaming flask, stop steaming and cool the whole room. The mass of the effect is m, and the blood is sent to the steaming flask twice with a small amount of alkane. Send the blood to the steaming flask. 6.7 Place the evaporation point in the windshield for 15+5 hours and collect it in the cooling flask. 1 me .
7 Calculation of results
7.1 Note: The content is calculated according to formula (1):
In Chinese:
The mass of the test column, in grams,:
The mass of the test column, in grams -
The mass of the oil-smoked blood after the joint work, in grams: gx:
7.2 Take the average value of the calculated length of three samples as the test result, retaining two significant figures: official
