Fiberglass Panel bonding sheet detection technique

In the producing method of the Fiberglass Panel bonding sheet, to confirm the standard, numerous technical necessities should be tested frequently. What's the review technique for covering the material Panel bonding sheet? Next, allow us to take a glance.

Here is that the content list:

• Resin content

• Gel time

• Resin fluidness

• Volatile content

Resin content

① A minimum of 25mm from the sting of the bonding sheet of Fiberglass Panel, cut three samples in keeping with the breadth direction to the left, middle and right. the dimensions of the sample are 100mm×100mm, and therefore the diagonal is parallel to the latitude and meridian. ②Weigh the warranted sheets of fiberglass construction products one by one (W1), correct to zero.001g. ③Place the sample during a muffle chamber of 524-593(, burn for over a quarter-hour, or burn till all carbides area unit removed. ④ Move the sample to a desiccator and funky to temperature. ⑤Weigh each bit (W2), correct to zero.001g. ⑥Calculation: organic compound content=[(W1-W2)/W1] ×100%.

Gel time

①Cut a 20cm×20cm sample from the middle of the Fiberglass Panel bonding sheet, knead the sample to form the organic compound powder that constitutes the metal sieve, then sift it onto a bit of fresh written report. ②Take regarding 20mg of organic compound powder and place it within the center of the new plate of the detector that has been hot to 171 (±0.5°C before. once the organic compound powder is dissolved, begin the stopwatch and stir the organic compound with a wood strip. ③ Stop the stopwatch once the organic compound thickens till the drawing is interrupted. The time is that the gel time.

Resin fluidness

① Cut four specimens at a distance not but 5cm from the sting of the Fiberglass Panel bonding sheet. the dimensions of the sample are 100mm×100mm, and therefore the diagonal is parallel to the latitude and meridian. ②Weigh (W1), correct to zero.005 grams. ③Fiberglass Pipe specimens area unit aligned and superimposed, a unleash film is adscititious, then placed between 2 chrome steel plates. ④ Place the plate and therefore the sample within the press at 170℃±2.8℃, press once, the unit pressure is one.4MPa±0.2MPa, and keep it for 10min. ⑤ Remove the sample and funky to temperature. ⑥ Punch a φ80mm disc from the middle of the sample. ⑦Weigh the burden of the disc (W2), correct to zero.005g. ⑧Calculation of organic compound fluidness of fiberglass construction products bonding sheet: fluidity=[(Wl-2W2)/W1] ×100%.

Volatile content

① A minimum of 25mm removed from the sting of the bonding sheet of Fiberglass Panel, cut three specimens in keeping with the breadth direction to the left, middle and right. the dimensions of the sample are 100mm×100mm, and therefore the diagonal is parallel to the latitude and meridian. ②Perforate a low hole in one corner of every sample. ③ Place the Fiberglass Pipe sample within the desiccator for one hour. ④Weigh one by one (W1), correct to zero.001g. ⑤Hang the sample in AN kitchen appliance and bake it at 163℃±2℃ for 15min. ⑥ Move the sample to a desiccator and funky for ten minutes. ⑦Weigh one by one (W2), correct to zero.001g. ⑧Calculation: Volatile content=[(W1一W2)/W1] ×100%
