Construction of gush filling engineering was 1960 company of Japan iron and steel develops a design to converter. Shaft of blast furnace of Yu Lian iron, torpedo is applied to hold bag of car, heating furnace, steel, vavuum pump in the palm to take off gas unit to wait gradually later.
Earlier, gush filling means has dry hair and wet. The dry-well type in season that amid has an advantage fills to be applied from beginning to end more general. But, dry hair spray fills put have soot and power of its spring back character of system of construction of more, engineering is weaker wait for blemish, because this is developed,devised half dry way (also say for half wet) gush fills technical, received the engineering construction form of low water portion and expensive stuff sex then, and makings conglutinate fills to lead advantage of colleges and universities without dust, gush when having engineering construction, be applied to popularize quickly consequently. Another, the carbolic confluence gush that returned development to design tall corrosion resistance and compressive strength of tall stick together fills makings, future also can be obtained apply.
Show level, gush filling makings is most normally repair makings, in the future, such thing also will changeless from beginning to end. The cause of filling makings of gush of a lot of application is it can fall in normal temperature, all of tall spend construction of Cheng of come off work, real operation also very brief change.
The carriage method of its raw material can divide according to of means of construction of gush filling engineering into dry hair, half dry method to mix wet.
Dry hair is to carry not the powder of moisture content, add in shower nozzle position sail upstream the means of the portion.
Half dry method is the powdery substance facilities of portion of water of carriage syncretic part, the way that goes water portion is added in shower nozzle position.
Wet it is the kind that carries the artesian well slop that adds water share.
Although, what send to working is technical interest interest is in drop off, but it still is the engineering construction means that each factory uses generally. Because do the that delivers repair range to spend with add sail upstream the portion has associated sex, because this development was designed full automatic gush filling equipment.
Full automatic software of spray filling system can be in full automatic repair amount of labor is made clear after measuring lining environment temperature. This system software not only in making repair works, specialization, and make repair work operates mediumly also maintained specialization, improved the character of the character that gush fills to be operated actually and engineering construction system then.
Of the eye land that develops a design to do law gush to fill partly head it is to prevent wet and complex beforehand mix up works. Because choose wet advantage relatively remarkable, nowadays technical interest is liked brake is wet treatment involving the use of tonics to restore the patient's health trying gush.
Half dry method and wet just began to apply before ten years, half dry method and wet among relatively.
The distinction of they and dry hair is in shower nozzle the position adds stiffening agent, it is wet very, go up in order to add the method of stiffening agent is more.
Nowadays, wet gush fills not only as repair makings engineering construction is applied, and also be applied as the engineering construction of the village inside attaint.
Spray paint uses the Zuo of equipment to fast cyclone gush enters commonly used place and suck Fu the surface in working, make spray. Spray also is very varied means, the commonnest also is a few kinds.
Have flame spray and plasma spray way, but very little in fireproof insulation material application. Splash law of broken bits spray, it is the service instruction that goes up in furnace with spray of high-pressured oxygen gun, this kind also is not common.
Work type spray way, it is this kind of the most familiar pattern, spray paint is shrunk to be passed to shower nozzle and water to meet according to pipeline by empty atmospheric pressure, in shower nozzle makings and spew of water mix up arrive in the job line. But gush enters the line in the job to go up, chip in of ministry branch screen resilience, probably, screen resilience is lower than jumping over taller, when spray, too big or energy is too small bad, the shift in answering to control spray gun up and down will ensure of spray layer thin thick well-balanced.
The Bao Hou of spray of every time of law of dry type spray is not OK too thick, too thick fall off very easily. Normally the state can not exceed 50mm.
Wet try spray way, be good negotiability fireproof and pouring expect with pump basis pipeline sends to shower nozzle, be gone to by spew of Zuo calm sb's anger coming back in shower nozzle in the job the surface. Gross 4 flow: Concrete of mix up, underwater, spew and condense. Rehabilitate of much in order to of this kind of means. Much in order to makes line instantly. Can produce li of line of production steel bag and burner instantly. Wet the characteristic that is to say that tries spray way is used convenient, need not stencil, cost cost is inferior, rate is rapid still.
Can be wet the conglutinate ratio that tries spray way is very crucial, if makings is medium water portion is more, can make coagulate first long, can not produce roam about or slippage condition, or meeting generation casts off a state. If agglutinate strength is not quite good, will be spray very not well-balanced or place of spray heavy panel brings about. Probably, complex material is not well-balanced it is bad, cause condition of fission, cascade very easily.
