Application fields of glass-squama colophony
Squama colophony has wide chemical bearing quality, good hot bearing quality, gas penetrability bearing quality, impregnant bearing quality, so it is widely used in many different fields.
1、Power house equipment for ejecting smoke and desulfurizing flue of assimilating tower, serum case for accident, case of limestone plasm, serum case for recycling of engine abrade.
2、Ironworks equipment of hydrochloric acid reclaiming equipment for desulfurizing of cookery equipment for acid washing
3、Petroleum store jar for crude oil
4、Chemical industry equipment for chlorine and alkali, dyestuff, chemical stuffs
5、Equipment for drainage and the disposal of wasted fluid concrete slot counteracting slot
6、Equipment for the disposal of sewage application of glass-squama in highly antisepticised paint
As a special antisepticised stuff, squama is used in the paint of antisepticise and makes the surface of the paint perfect. So glass-squama has the quality of excellent antisepsis function and becomes new antisepsis stuff that can attract people’s attention.
Glass-squama dope has been adopted in many enterprises in our country and achieved good result successfully, such as, Qilu Petrifaction Company, Shanghai Baogang Company, Tianjin Alkali Factory, Tianjin Chemical Plant, Victory Oil Field, Daqing Refinery, Guixi Smelting Factory
Glass-squama dope can be widely used in many fields , e.g. petroleum and petrifaction pipe laying ,storing pot, facility, establishment in sea, artesian well flat on the sea, chemical tank for storing gas ,chemical windpipe for gas transport, facility for ejecting smoke and desulfurizing in metallurgy power house and also the anti-oozing layer for glass-steel equipment.
The antisepsis mechanism of glass-squama
Glass-squama is an extremely thin glass fragment that is melted by 1700 Centigrade and blown by Special craft. It is applied by the abroad for many years.
When in the state of being melted by high temperature, glass which is processed by special craft, it makes the glass-squama have the characteristic of more intensity and less specific gravity than common glass.
Glass is abio-material. Its makeup contributes a lot to a nicer capability of enduring chemical medicine and resisting aging. The glass-squama is very thin, the squama dope by way of right construction makes that it can equally file up, press and arrange with radicel system. It looks like pieces of scale, layers of armature and forms the exact anti-oozing layer. (Some people call it labyrinth structure. It achieves nearly hundred layers according to the test, and makes the approach of cauterization to the to the protected radicel flexural. The approach and time of medium-oozing have been prolonged, the resisting of osmosis and age of eroding bearing have been improved.
Many glass-squama in the coat forms lots of small areas, makes the tiny crackle and tiny air bubble in the coat segmented, slows down the oozing speed of medium and reduces the medium oozing rate. The osmosis of resisting medium of glass-squama coat is several times better than other medium materials.
The existing of glass-squama not only reduces the difference of hot-swelling coefficient between coat and bottom material, but also the induration constringency of the coat itself. The induration constringency of glass-squama coat is only part of other materials. It can not only help to resist the chapping and desquamation of the coat but also to improve the clinging and anti-striking function.
Exterior disposal of glass-squama
The glass-squama disposed by even jointing-medicine type of silicon and alkyl can clearly increase the felting force between scale and colophony, efficiently increase the characteristic of resisting seeping, at the same time decrease the characteristic of drinking water by coat. Further more, disposed glass-squama has a good characteristic of floating in colophony, it makes for paralleled arrangement between squama and radicel system in order to raise the characteristic of resisting seeping of the coat.
Dosage of the glass-squama
The glass squama can be added into coat can never be too small, and of course not be too big. Right dosage can reach a very good effect. Be short of squama can form the superposition arrangement among pieces and pieces, then the resisting penetrability characteristic of the coat is not good; with the dosage increase, its screen function will increase. But the dosage is too large, it will go against the coat arrangement among squama, will make disorderly and unsystematic arrangement, and will add large interspace in the coat, so the compact characteristic of the coat will decrease. Therefore the squama dosage has a best bound; it should be between 20% and 35%.
Composing of the glass-squama dope:
Glass-squama dope is a kind of highly antisepticised dope taking eroding-bearing colophony as the main membrane substance, taking squama as stuff, and taking some aiding medicine, e.g. solicitation medicine and accelerant.
The dope content is big in dope mucus mud ,the content should be between３０％～４０％。Liner of squama mucus mud has achieved great success in the application of desulfurizing and smoking-ejecting equipment. Relying on its special capacity, convenient construction and strong repairing nature , glass-squama dope becomes the important highly antisepticised dope increasingly
