The performance of combustion of PVC is not good, away from the fire Jimie, Inner Mongolia coal bin liner, yellow flame, the bottom is green, Fuzhou coal bin liner, white smoke, are flame-retardant plastic; burning there irritating odor release hydrogen chloride, soften when burned. Practical use because PVC contains a lot of organic esters (such as DOP) plasticizer flammable, so consider retardant problem. PVC is used alone, there antimony trioxide flame retardant. If and chlorinated flame retardance and easier to use. Transparent PVC should use phosphate-based flame retardant, tricresyl phosphate common (TCP) TCP but poor low temperature performance. Good performance halogen-containing phosphate, Shanxi coal bin liner, but the price is a little expensive. 11.PVC transparent sheet PVC impact modifier was added and organotin stabilizers, by mixing, plasticizing, rolling and become transparent sheet. Use can be made of thin-walled thermoformed transparent containers or for vacuum packaging, is an excellent packaging materials and decoration materials. 12. Other doors have a hard shaped material assembled. Have jointly occupy the doors and windows with wood windows and doors aluminum windows and other markets in some countries; wood materials and steel building materials (northern seaside); hollow container. A virtual circuit is one of the services provided by a packet switched network (the other is a datagram service), Ningxia coal bin liner, simply put, is through control mechanisms within the network between user hosts to establish a virtual logical connection, and ensure that the messenger bag before uploading the correctness and sequence of communication to be set up and dismantle virtual circuits. PVC is a virtual circuit established when the network is initialized, and the virtual circuit remains. X.25 networks and B-ISDN provides PVC services. PVC plastic bags are generally disabled.
