Pouring makings construction uses:
One, batch mixing equipment must get ready before construction, fountainhead and send makings tool, must assure the batch mixing of concrete and carried need. Equipment of requirement batch mixing inspects construction dosage size, every time batch mixing 300-500KG is advisable, work first, dry mix 20 minutes, dry mix Wu to be sure additive together Join, add water again, for many times a few adding water, significant mixing time is 6-8min, the requirement sends makings oar to the time inside the mould to cannot exceed 10min.
2, construction is spent with the cleanness of water should reach a nation quality of 2 class drinking water, water is warm not under 10 ℃ , not prep above 40 ℃ .
3, when batch mixing, every bag that pack weighs 25KG, every time agitate asks whole bag is used, cannot 1/2 or 2/3 tear open bag use.
4, when feed in raw material, there is additive inside every bagging two pouch, tear open packet of current affairs to be found surely, open additive certainly join come here in packing the burden inside, cannot wrap bagging to adjust with other or overlay is used.
5, the quantity that add water inspects the site pouring circumstance and calm, recommend water consumption 6%±2% .
6, pouring when construction, should check die device to deny first firm and reliable, guarantee against can leak oar, if discover makings oar flow becomes poor, be abandoned stoutly and need not.
7, when construction, if discover,have leakage thick liquid or empty, should instant a proper limits inside pouring makings body is eradicated clean, fill afresh pouring.
8, pouring and finishing hind, should clear in time the spot, when every construction class has sex, want to expect those who had mixed the oar is gone, if exhaustless processing technique is the same as the 7th.
9, pouring and finishing hind, want natural conserve 48 hours ability drawing of patterns, prep above of the air temperature after drawing of patterns 35 ℃ or environment are too dry, should adopt defend wet measure appropriately, but can drench directly anything but water.
10, drying-out, can undertake with synchronism of body of heater.
Pouring requirement of makings state level:
1, fireproof and pouring expect as home heat is versed in place of kiln furnace equipment has use fireproof data, its quality problem also is to be weighed particularly should, the country decided a level to fireproof material. But pouring expect without specific country model asks, but have specific executive level to material itself, be being used or buy fireproof and pouring when expecting, use those who accord with national level as far as possible, can be in the assurance of the oldest rate of the project carry out.
2, fireproof and pouring expecting is by fireproof aggregate, pink makings, additive and bond are comprised. Arrive again from his raw material, additive fireproof and pouring the muddy of makings is made, we each pace needs to choose meticulously, absolutely cannot use what do not accord with a standard. Fireproof and pouring stuff is ordinary using the site with pouring, shake or the method of tamp is irrigated build shape, also can make prefabricated component use, fireproof and pouring makings standard is given priority to with national level, fireproof material handles a demand to get used to high temperature in use process, should have in enough high air temperature falls and not bate, not the function of melt.
Fireproof material international implements a standard:
1, standard of adiabatic and refractory products
Fiber of pottery and porcelain of GB/T 3003-2006 fireproof material reachs goods
GB/T 3994-2005 sticks earthy and adiabatic firebrick
Firebrick of qualitative heat insolation of GB/T 3995-2006 tall aluminium
Goods of calcic heat insulation of GB/T 10699-1998 silicon acid
2, indeterminate form is fireproof data standard
GB/T 2994-2008 tall aluminium is qualitative fireproof slop
GB/T 14982-2008 sticks earthy and fireproof slop
Heating furnace of GB/T 22590-2008 steel rolling is used fireproof and pouring makings
3, fireproof data basic standard
GB/T 2992-1998 (2004) size of general firebrick shape
GB/T 4513-2000 (2004) fireproof material classifies indeterminate form
GB/T 10325-2001 (2004) boarding is fireproof goods samples check and accept regulation
GB/T 10326-2001 (2004) refractory products measure, exterior reachs boarding the examination method of section
Fireproof material packs GB/T 15445.1-2008 indeterminate form, mark, carry and store
GB/T 16546-1996 (2004) refractory products packs boarding, mark, carry and store
GB/T 16763-1997 (2004) boarding heat insolation is fireproof the classification of goods
GB/T 17105-2008 aluminous silicon fastens compact figuration refractory products classification
GB/T 17617-1998 (2004) fireproof raw material and indeterminate form are fireproof material sampling
GB/T 17912-1999 (2004) rotary kiln uses firebrick appearance measure
GB/T 18257-2000 (2004) rotary kiln heats up mark with firebrick
Refractory products classifies the alkalescent and compact figuration that quantity of carbon of GB/T 18931-2008 incomplete is less than 7 ％
Component of GB/T 20511-2006 refractory products regulation
4, raw material standard
Mud of acerbity brine of GB 201-2000 aluminium
Magnesia of GB/T 2273-2007 agglomeration
Corundum of palm of GB/T 2478-2008 common abrasive
White corundum of GB/T 2479-2008 common abrasive
Carborundum of GB/T 2480-2008 common abrasive
Condition of technology of silicon of GB/T 2881-2008 industry
Black lead of GB/T 3518-2008 scale
The detailed standard that above standard is the requirement when requirement of pair of fireproof material composition, technology, manage changes the project such as index to do specific check to measure.
