pu sandwich panels for building

Sandwich panels consist of two outer metal colored sheets with insulation polyurethane core between them. The metal sheets are bonded to the insulation core with specialized adhesives. The outer surface of the sheets can be flat, slightly corrugated ,water ripple or with a significant profile (eg. for roofs or external facade design). A huge assortment of shapes, coatings and colours is available. Because sandwich panel installation requires only a limited number of mechanical fasteners (eg. screws), the resulting constructions avoid significant thermal bridging. To achieve distinctive architectural features, panels are connected with dowels.

Q:Why aluminum foil should be used in capacitor material of distributors?
The normal metal capacitor, especially CBB21/,DV/, impulse current of its turn-off voltage is very high. The capacitor material of distributors, if the distributors of ignitor can't bear such high impulse current. Using CBB28 or CBB8,in which the capacitor can bear a higher impulse current.The ratio of DT is higher.

Q:Does the aluminum foil belong to metal material
Yes.
Q:How to measure the thickness of aluminium foil flake?
Measure the correlation value of aluminized paper with a dividing rule, then you can get the area(s) of it. Measure the mass of aluminized paper with a balance, then you can get its volumr by using the density formula m=PV(the density of aluminium can be gotten from density table).Finally, using the volume formula v=hs, you can get the thickness of it.
