Description
Technical field
The invention belongs to detect field of measuring techniques, especially a kind of cement counterweight dispensing and manufacture method.
Background technology
nullI.e. there is being equivalent to " power " of counterweight in the Xia dynasty in China，Between more than 4000 year hereafter，The different dynasties have " power " of difformity and material as the measurer weighed，In modern mass measures，Counterweight is the etalon of quality measurements transmission，Quality measurements is in kind for unique reference device with the platinumiridio prototype kilogram being saved in International Bureau of Wieghts and Measurements of France，Counterweight is all divided into country's kilogram benchmark by various countries、Country's kilogram secondary standard、Kilogram working standard，And by kilogram times amount and the working standard group that constitutes of component and the working standard counterweight such as each，In the past in Europe，For more preferable equal value exchange，Then people is had just to have one lever of sheep and cattle，Accomplish balance as far as possible，This was with regard to so-called sheep or Niu Zuowei counterweight the earliest at that time，But As time goes on，Slowly just had the blank counterweight that stone makes，But when time error is bigger，Then through the continuous evolution of thousand of years，Processing reprocessing，Thus become the counterweight of today，Rustless steel mark counterweight is formed with system，Precision weights etc.；nullThis counterweight uses the phenomenon can forbidden after time length，Cause mainly due to two reasons，On the one hand counterweight will occur the wear phenomenon of counterweight after using the time longer，This has the biggest harm to the use of counterweight，Two aspects are the inaccurate phenomenons caused owing to getting rusty，This needs us when in use just it is noted that deposit，If also can get rusty even rustless steel counterweight uses for a long time in the environment containing chloride ion，Such as Sal、Sweat、Sea water、Soil etc.，But after counterweight abrasion or getting rusty，Weighing results the most also can be affected，If counterweight gets rusty，Measurement result is less than normal，If counterweight weares and teares，Measurement result is bigger than normal，If because counterweight gets rusty，The ferrum on rustless steel counterweight surface defines ferrum oxide，Many oxygen atoms，Certainly its quality can become weight，Thus the weight of the article of weighing drawn can alleviate relatively，Same reason counterweight wear measurement result is bigger than normal to be just understood that；If these counterweight weighing results are inaccurate just can only scrap process, and because the highest the scrapping of cost wastes greatly so that resource, particularly being not required precision the highest in part, but must also frequently use the place of counterweight, the counterweight of this costliness seems incompatible with.
The present invention seeks to study that a kind of non-corrosive, volume be big, a kind of cement counterweight dispensing of economy and durability and manufacture method.
Summary of the invention
The technical problem to be solved of the present invention is to provide that non-corrosive, volume be big, a kind of cement counterweight dispensing of economy and durability.
The present invention adopts the technical scheme that:
A kind of cement counterweight dispensing, according to the mass fraction, it is made up of following composition:
Sandstone
45 parts
Iron powder
20 parts
Carbon dust
15 parts
Calx
24 parts
Lead
10 parts-15 parts
Aluminum sulfate AL2(SO4)3
4 parts
Zinc sulfate ZnSO4
4 parts
Calcium chloride Ca2Cl
5 parts
Calcium sulfate CaSO4
6 parts
Alumen KAI (SO4)2·12H2O
8 parts.
Lead has radiation protection, and adding lead can increase the radiation resistance of cement counterweight, increases the service life, and additionally lead has the effect of counterweight, uses lead can improve the degree of accuracy of cement counterweight.
Cement counterweight to be made, improve cement counterweight intensity, above dispensing it is critical only that the relation adjusted emphatically between lime saturation ratio (KH) and silica modulus (n), i.e. KH be 0.7-0.9, n be 2.1-2.5.
Utilize above-mentioned material, make the forming method of cement counterweight and specifically include following steps:
1) it is made into compound by said ratio, grinding in grinding machine, is sifted out by 0.05mm square hole screen；
2) material crushed in step 1) being put into casing, be stirred, stirring 20min is to uniformly mixing；
3) by step 2) mix expects the water that addition is appropriate, to sticky shape；
4) using reinforcing bar to make framework, framework is grid structure, grid structure more than one, and each grid length and width are equal, and length and width is all between 10CM to 30CM；
5) framework that step 4) obtains is put in mould；
6) material that step 3) obtains is poured in mould, wait 15～20min to be formed；
7) open mould, i.e. can be taken off cement counterweight；
8) one layer of plastic cement of cement counterweight paste outside that will take out in step 7), plastic cement thickness is between 10CM to 30CM.Paste plastic cement and can increase the impact resistance of cement counterweight, anti abrasive characteristic, and ensure that cement, without coming off, occurs without dust.
Advantages of the present invention and good effect be:
1) the cement counterweight utilizing the present invention to make is a kind of for carrying out the cement counterweight bred, and compared with existing counterweight, the present invention has that non-corrosive, volume be big, the feature of economy and durability, low cost of manufacture；
2) utilizing the present invention when making cement counterweight, it is possible to the effective setting time accelerating cement, prevent cement from coming off, rapid solidification can effectively improve work efficiency, easy to use, has the value of popularization and application；
3) utilizing the present invention making cement counterweight, comprcssive strength can reach about 1200KN/.
