A lot of clients are firm mortar of gesso of gush of machine of bring into contact with, not be very clear to the function characteristic of mortar of machine gush gesso, have doubt to using the effect, whether will use mortar of machine gush gesso to also be put in a lot of apprehension in the project henceforth. To let mortar of understanding of broad travelling merchant and gesso of familiar machine gush, everybody was collected to know in the information that feedbacks from the market go up to be put generally in a few problems, seek advice from relevant expert technically to undertake solution, so that better conduct propaganda is mixed,popularize mortar of machine gush gesso.
One, do cement and gesso do machine gush material what to actor of low quality have each?
Cement and gesso can make machine gush material, look from function, gesso intensity and body of wall of average basic level match quite, won't appear cement mortar craze and empty beat problem; From energy-saving on look, gesso bad news can have the 1/3 of cement only, carbon dioxide discharge capacity has the 1/10 of cement only; From the point of environmental protection angle, gesso has such as a lot of environmental protection characteristic such as qualitative light, absorption of heat, sound insulation, flame retardant, auxiliary breath, OK and infinite loop is used, accord with a country to develop the strategic goal of industry of energy-saving environmental protection. Plasterer of the wall inside the developed country 90% it is use gesso mortar, gesso mortar also is direction of progress of domestic plasterer material. Look from market price case, cement mortar is low, be in commonly 200 ～ 300 yuan, gesso mortar wants tall, price of mortar of gesso of foreign machine gush is controlled in 2000 yuan, mortar of gesso of domestic machine gush is controlled 1000 yuan only. Although mortar of the gesso on the price has not compared cement, but the integrated element such as upkeep costs of consideration later period and environmental protection benefit, as inside wall plasterer material, mortar of cement of the excel on gesso mortar function, can rise inside wall illuminative character and class.
3, do meeting craze and sky rouse face of back wall of gesso mortar spray?
The craze of wall plasterer is mixed inside empty beat is the problem that everybody cares quite. Gesso mortar won't appear craze and empty beat phenomenon, because,basically be:
The first, mortar of machine gush gesso uses compound additive to produce commonly, increase gesso mortar and basic level felt to spend thereby, mould of change gesso flexibility, those who make match with aerocrete block photograph, reduce plasterer gesso shrinkage, increase gesso water retention, put an end to thereby produce craze and empty beat phenomenon.
The 2nd, mortar of machine gush gesso is to pass the eject after pressure air is quickened to arrive on metope, it is certain to have return spring, this means wet mortar and basic level to have very good conglutinate power, wet mortar is by continuously eject arrives on metope, have very good continuity, prevent metope sky effectively to beat the venture with craze.
The 3rd, before spray construction, should be in base wall material connects character place, and in distance plasterer surface 1/3 place installs alkalescent reseau cloth, in order to prevent empty beat and craze.
5, how to make the both neither when gesso mortar spray blocks a canal up not to flow again hang?
Cause a valve main reason: Mortar grading is unreasonable, exist to big grain produces jamming of cartridge or shell case and block a canal up; The consistency value of mortar is too little, fluidity is poor; Did not clean pipeline beforehand; Operate inexperience, open pump to send valve to did not open baric valve to cause a valve thereby only for instance. Cause shedding the main reason that hangs a phenomenon is mortar sticky consistency is too low, as insufficient as force of basic level conglutinate.
So, prevent mortar of machine gush gesso to block up be in charge of and flow hang, want to choose mortar of machine gush gesso correctly above all, because of quality reliable gesso mortar has reasonable grading already, mingled the agent that defend water, pump to send the compound additive such as the agent again, pump sends gender, sticky consistency and fluidity to be able to satisfy machine gush requirement. Next, should adjust according to manual of machine gush mortar water capacity comes constant, the machine will be automatic batch mixing, the quantity that add water also has not wanted too much little, cause mortar to flow easily too much hang, cause mortar spray too less not fluent, later period make level is difficult. The 3rd, master the operation of machine gush equipment correctly, pipeline should be cleaned after construction is finished every time.
7, blow lever to stick board how to do?
General mortar, to increase with force of wall body felt, sticky consistency is bigger, such meetings cause later period construction to compare difficulty, blow lever not smooth, stick easily board, cannot come through increasing water to measure at this moment attenuant consistency solves a problem, meet otherwise shedding of item of expenditure is hanged, flagging phenomenon. Solve blow lever to stick board the most efficient way adds the problem to be touched right amountly namely change lubricant, touch change lubricant is had lubricant, touch change, defend the action such as water, in suspension, can improve application property, can blow a gender, make blow lever smooth, not demanding, do not stick board.
8, how to solve gesso mortar to not be able to bear or endure the problem of water?
The higher bibulous rate of gesso and inferior bate coefficient are to cause do not be able to bear or endure the main reason of water. The bibulous rate of general gesso 72h is amounted to 28% the left and right sides, bate coefficient is 0.35 the left and right sides. Be able to bear or endure anything but for solution the problem of water, add right amount abhor water agent and borax in gesso mortar commonly, the free water that abhor water agent and borax can make cream body condenses body is released, increase gesso solid density, reduce gesso water absorption, promote gesso the intensity after sclerosis at the same time. Through reasonable it is OK to match example record lower the bibulous rate of gesso 8% the left and right sides, bate coefficient rises 0.83. Additional, after hutch defends plasterer of ground floor of use gesso mortar, when the shop sticks ceramic tile, use shop of ceramic tile glue to stick ceramic tile, with waterproof tick off seam an agent to tick off seam, ensure moisture cannot permeate gesso mortar layer.
9, what how eliminate the appearance after blowing lever is coarse with stoma?
After blowing feet with H, hard to avoid appears coarse with stoma, can be eliminated at this moment through blowing working procedure receiving light. This working procedure needs to use wing section drawknife. When drawknife of use wing section is operated, it is need data is enough still soft when undertake blowing wiping, can use wing section drawknife to will blow the makings oar that come down to close the coarse place on metope and petty hole fill so; 2 it is to use fixed one side to undertake blowing wiping to the wall from beginning to end, those who avoid other one side is not smooth cause new rough whole; 3 it is wing section drawknife and metope should maintain horn of about 75 ° to undertake blowing wiping. Through this kind the operation just can discover and eliminate tiny rough whole.
10, is mortar of machine gush gesso general is spray much thicker?
The ply of plasterer layer should design a regulation by the building. According to " construction of building adornment engineering and check and accept a standard " regulation, the average total ply of plasterer layer should be:
Ceiling -- 15mm of concrete of batten, air brick, cast-in-place; Prefab concrete 18mm; Gauze 20mm.
Inside wall -- common plasterer 18mm; Intermediate plasterer 20mm; Advanced plasterer 25mm.
Mortar of general machine gush gesso but 20mm of spray 8mm ～ , average spray ply is 10mm. Mortar of gesso of PABC machine gush but 35mm of spray 3mm ～ , average spray ply is 8mm.
