This test with a small sample length 127mm, width 12.7mm, the maximum thickness of 3.2mm. In the absence of ventilation test chamber. The top of the specimen (6.4 mm place) is clamped with a clamp on the bracket and the longitudinal axis of the specimen is kept vertical. The lower end of the specimen is 9.5mm from the lamp tip and 305mm from the dry absorbent cotton surface. Bring the Bunsen burner and adjust it to produce a blue flame with a height of 19mm. Place the Bunsen Lights flame at the bottom of the sample for 10s, then remove the flame (at least 152mm away from the specimen) and write down the sample. Burning time. If the flame of the sample within 30s after removal of the flame is extinguished, the original lamp must be moved under the specimen again, re-ignite the sample for 10s, and then remove the Bunsen burner again and note the flame burning And flames burning the burning time. If the sample droplets drip, let it fall into the sample under the 305mm cotton, to see whether it ignited cotton. If the absorbent cotton is on fire, the rating should be taken into account. Specific grading indicators are as follows. Test Item 94V-094V-194V-21 Ten-time ignition Total flame burning time Maximum value (S) Individual flame burning time Maximum value (s) Flameless burning time (s) Yes Flame drop No No Allow only short time Burning general UL yellow card on the thickness of the test strip is divided into: 1/8 inch, 1/16 inch, 1/32 inch thickness, that is, 3.2mm, 1.6mm, 0.8mm three grades test.

Q: I added the space 18 degrees opened for 5 hours or not cold, we all know how is it? More
Common points are all sandwich panels, with a hard protective layer, the difference is the middle of the different materials, such as polystyrene board, polyurethane board. Polystyrene board which is the most common, because the price is cheap, easy to use so the use of more, but if the temperature is more than the requirements of the chicken inertia glycosylation moxibustion slim faint words, polystyrene board is not satisfied , So there is a polyurethane sandwich panels, polyurethane thermal conductivity of less than 0.. in the existing insulation materials, large quantities of processing, be the best. But because of its process is more complex, and the cost is relatively high, so with less, the common combination of cold storage and the like, I believe that with the economic and technological development, polyurethane sandwich board market share will be more and more High
