6 Ways Sluggish Economy Changed My Outlook On Fire Retardant Cable > 자유게시판

INCA DC333 The expandable fireproof paint in water base for both interior and exterior. INCA DC68 Interior furniture and synthetic fabrics are the number one contributing factors to hearth spread and smoke technology right this moment. Rinse Method : All weight fabrics may be dipped or rinsed processed. Another object is to offer a method of making tape having one or more of the above characteristics. Spray Method : Lightweight fabrics: Ought to be sprayed once on every aspect. Medium and heavy weight fabrics: Needs to be sprayed two or extra instances on each aspect. The primary motive for this is because the polyester movie and adhesive coating thereon is thinner and fewer dense than the relatively heavy unvulcanized rubber or neoprene barrier coating calendered on the prior tapes. When the tape is constructed in this fashion, the polyester movie 24 therein is considerably steady and devoid of pinholes and presents a continuous, easy surface in order that the tape 14 may be served from a roll without the film adhering to itself and selecting off from the scrim. When the tape is constructed in this trend, the polyester film 24 therein is considerably steady and devoid of pinholes and presents a steady, clean floor so that the tape 14 will be served from a roll with out the film adhering to itself and selecting off from the scrim.

In a typical tape, the polyester movie 24 is on the order of 0.5 mil thick and the adhesive layer is barely on the order of 0.2 to 0.3 mil in thickness. In a typical tape, the polyester film 24 is on the order of 0.5 mil thick and the adhesive layer is simply on the order of 0.2 to 0.3 mil in thickness. Then the coated movie and scrim 22 are regularly introduced together in a drying oven in order that the 2 turn into bonded collectively. Rather, as identified above, the scrim 22 is maintained under the next tension than the movie in the drying oven. Rather, the scrim 22 and coated movie 24 are maintained under completely different lengthwise tensions which causes the two to be urged collectively within the drying oven with the result that they grow to be firmly bonded to one another. Then the coated movie and scrim 22 are progressively introduced together in a drying oven in order that the 2 turn into bonded collectively.

During this bonding course of, the coated movie and scrim are usually not pressed together with any nice amount of power. In precise apply, the barrier layer tends to "choose off" from the cloth as the tape is unwound from the roll and it also undergoes a certain amount of cold circulation. Also, the unvulcanized rubber-coated glass cloth is utilized to the conductors within the form of tape which is unwound from a roll. A barrier layer in the form of a skim coat of flame-retardant unvulcanized polychloroprene is calendered on the glass cloth and eventually an outer jacket of artificial rubber is extruded in place onto the tapered conductors and fused to the underlying barrier layer. Pat. No. 3,602,636. Basically, it uses an open weave glass fiber tape wrapped around the clustered conductors. It relates more notably to fire-retardant insulation in sheet and tape kind for cables which are exposed to the weather and which should be capable to withstand tough usage, e.g. a service entrance cable. An outer jacket 18 of a waterproof resinous material reminiscent of polyvinyl chloride, neoprene, or the like, is extruded in situ over the wrapped conductors, thus finishing the cable 10. As shall be seen presently, the tape 14 and jacket 18 together type a double continuous insulating barrier which is considerably impervious to moisture and the weather.

Also, by advantage of the low viscosity adhesive working up between the glass fibers 22a within the scrim, the tensile energy of the tape is definitely enhanced because the adhesive seems to kind a buffer between the person fibers 22a, decreasing their tendency to abrade one another. Still another object of the invention is to provide a cable tape which has a comparatively high tensile power. Still additional, the tensile strength of the prior cable tape is just not as high because it may be, although it does cross the UL test for this characteristic. The net result's a superior insulating, bedding and binding tape which might be made at a lower price than prior comparable merchandise and which, when integrated into an exterior cable system, allows the latter to easily go all of the UL exams for such cables. Exterior cable of this type have to fulfill the stringent test requirements of the Underwriters' Laboratories, Inc. For example, service entrance cable, which is the cable which conducts electricity from overhead power lines into a consumer's house, must go the UL 300 amp. Yet one more object of the invention is to provide a service entrance cable tape which satisfies all the UL assessments.
