Moco at the invitation of the Thermo! Insulation Society in Philadelphis, Pqjb on December 3th, 1966. '5 SPRAYED FIBRE INSULATIONS Sprayed fibre insulations are o means of forming and applying insulotion cooting* by sproying fibres onto the surfoce to to be insulated. While there are presently several systems involved with the spray process, we shall talk about the systems incorporating the use of 100% African asbestos fibres with hydraulic setting and curing inorganic binders. This system, therefore, is the process of sproying these blended and prepared 100% asbestos fibres with the inorganic binders activoted by jets of atomized water onto any surfoce to be insulated. This system is designed to be a high temperature insulation involving elevated temperotures where block type insulations were and are being used. It is not to be con sidered for use on units where the surfoce temperature would normoily foil below ombient or thot of the surrounding air. This insulotion cooting has a "K" foctor s. i;ur to that of calcium silicate block. However, when in ploce it has been repeatedly found that the ccfuo! :;.J rsce hos been 'j*ir than what it wos calculated to be. This is primarily due to the fact that the coating is intimately in contact with the surface to be insulated, ond is free from seams which are opt to reduce the efficiency of block-type insulation after it is in place. The density of sprayed asbestos insulotions, while normoily applied, will average approximately 12 lbs. per cubic foot. It con be applied so as to range between 9 and 13 lbs. per cubic foot, depending on the nature of the application, ond on the hot surfoce temperature involved. The compressive strength of these sproyed coatings is about 25% compression at 5*7 lbs. per square inch. Flexural strength ranges from 9 to 14 lbs per square inch. Concerning contraction and expansion abilities, if has yet to crack or seporate when used within its designed temperatures due primarily to the fact thot the insulotion is in one piece and normoily in `direct ond intimate eontoct with the expanding or contracting surfoce, ond, os such, the insulotion actuolly moves concurrently with the surfoce insulated. This does not occur with rigid block-type insulations. The question onses why go to a spray-type insulation when there are a multitude of insulotions in mat, blanket and block form which hove been used throughout the years with knowledgeable results. These results, however, are not always the most desirable, economical or sotisfoctory. Therefore, a long time ago, octually about 35 years ago in Englond, the idea developed of applying an insulation coating by some sproy method, instead of making o blanket or felt to fit, and then in serting it, impinging or enveloping this surfoce to be insulated. Some of the requirements were that the insulation cootingj applied by the spray process were to be economical, durable and meet the insulation requirements of the material it is to replace. The first attempts consisted of a unit similar to o textile carding mochine, which would take asbestos fibres, previously blended with inorganic binders, cord them, and instead of forming Q film which became o felt or rove, dropped the opened fibres onto on impeller, which sent them through an air system contained in o flexible hose of approximately IV in diameter. These fibres emerged through a bullet nosed tube ottached over a standard spray gun, which supplied atomized woter to the pretreated fibres just before impinging onto the surfoce to be insulated. It was found to be rother successful ond subsequent refinements in equipment have increased its potential tremendously, so that it hos expanded in use since since thot time. Not only did it meet the requirements, but set some of its own: The coating fits perfectly: The cooting eliminates oir circulation between the insulotion ond the surfoce bulllwOol MWBB-0006033 The coating hos no |Oints: ' The coating eliminates cuttings which resuit in woste: The coating can be applied with minimum reinforcements, if any: The coating thickness can be controlled: In oddition to the above, this some coating aids in fire resistance, onti-condensotion, onti-corrosion, anti-drumming ond acoustical improvement. - Therefore, based upon the economic and time saving foctors, more ond more componies, whether they are the eventual user or the constructor, are giving the sprayed asbestos method of applying insulation a very serious look if they ore not already one of the users. Recent histories of savings hove initiated major programs in some refineries ond public utilities on the maintenance end, and also the large generator manufacturers in the original equipment classification. One hundred percent asbestos sprayed insulations ore already m thestondcrd specifications of Foster-Wheeler, Babcock & Wilcox ond others. Where is it used? This coating is used where requirements such as expansion, contraction, vibration, corrosion prevention ond convection effects demand o satisfactory yet ecc->omicoi insulation. Sproyed asbestos fibre cootings hove proved very successful in meeting these requirements. Th.s process has oeen jsed in power generating plants, oil refineries, chemical process plonts, metal manufacturing and process plants, where heof conservation, uniform distribution of heat and protection against the effects of heof ore important. It is difficult to soy why it took so long to finally arrive in the United States. However, acceptance of sproyed asbestos insulotions s increasing in leaps ond bounds. Specifically, however, sprayed asbestos insulations are not the final cure-oil for all our insulotion problems. Its use should be seriously considered for intricate surfaces where it is difficult for block, blanket and mat insulations to form an intimote and continuous cooting. While in the post, it has been very evident on steam turbines, lorge diameter breeching and piping, it is also being used on lorge boiler walls and vessels of sizeable diameters. It ts difficult to forecast the ultimate to which the sprayed asbestos insulation process will be used os 'a) wherever the process hos been accepted on a maintenance level, the customer hcs used it where it was never considered before, and (b) os new equipment is being designed, so are new in sulation requirements, and a sprayed process is contmously being investigated for possible use. When sproyed asbestos fibres (I like to soy, personally, 100^3 asbestos sproyed fibre insulotions), are used it is pnmorily os o matter of economics. In todays economy we hove two principle factors which should ploy on important part in select ing on insulation cooting; . 1 Applied Cost 2 - Speed of Application Applied cost: Whether the insulotion is to be applied by the maintenance department or a contractor, the cost of material ond lobor involved with the application hos been considered as one for a long time. Recently, however the "system" hos been emerging as an important factor. This system involves the insulation ond the weather-proofing os well. Without mentioning names, three well-known coating manufacturers hove recognized the eose and economics of applying their cootings over sprayed asbestos insulotions One mojor boiler manufacturer hos even gone so far as to develop on en closure for their packoge boilers, consisting of fiberglas reinforced with polyester resin. They now intend to enter into competition with metol boiler lagging. Speed of Application: It must be recognized, where a project demonds a minimum time allowed for insulotion, the forces of lobor could be mcrsholied ond put to work, if they could be found. While there ore cases where the application of mots and boards can be faster than cootings of sprayed asbestos, we hove heartily recommended the use of those products. However, when elevored temperotures prohibit the use of these products, it must be recognized that when one machine normally operated by two men con apply up to 2,000 board feet per 8 hour doy, it has a little merit. As a motter of fact, this some mochine can apply a coating of finishing cement wh.ch is for the interior applications ond as a bose for standord weather proofing on exterior units, thus facilitating a more repid application of your stondard mostic weather-proofing. 03112052 ASBESTOSPRAY CORPORATION High Temperature Insulation issued: October 26th, 1967 TECHNICAL BULLETIN Mechanical Reinforcement and Support of Asbestospray High Temperature Fiber Insulations.
