Description
Technical field
The utility model relates to building implements material technology field, more specifically, relates to a kind of common premixing mortar automatic arc spraying system.
Background technology
Compare with conventional on-site preparation mortar, the technical advantage of premixing mortar is embodied in: premixing mortar raw material source steady quality, through the strict handling procedure of factory, for the production of raw material quality be obviously better than the raw material that conventional on-site is stacked; Premixing mortar, through modern hybrid technique, has guaranteed the accuracy of cement mortar ratio, the uniformity of mixing; Premixing mortar, by plant produced, can equably, reasonably add the Admixture that many building-sites cannot add; Premixing mortar can meet the needs of different building operations engineering methods in time, is the construction material of novel construction matching performance excellence; Premixing mortar is easy to use, and efficiency of construction is high.
Although premixing mortar is being produced and performance etc. has a lot of advantages compared with conventional on-site preparation mortar aspect many, but, premixing mortar is also faced with series of problems in extension process, causes that social awareness is low, industry threshold is low and enterprise investment is waited and seen, logistics facility investment cost is large etc. as on the high side.Study carefully its main cause, the Main Bottleneck that restriction premixing mortar is promoted is in price---and it is larger that one-time investment is produced in the batch production of premixing mortar; And the prices of raw and semifnished materials of preparation premixing mortar rise steadily, the technical requirements of production technology is higher in addition, and the cost of production of premixing mortar is high more a lot of than traditional mortar.
Meanwhile, domestic premixing mortar market is flourish, cost of labor constantly increases and quality, efficiency and the environmental requirement of construction wall plastering construction improve constantly, traditional-handwork plastering construction is just progressively lost advantage with low cost, and the defect that its labour intensity is large, efficiency of construction is low shows just gradually, traditional-handwork plaster and current social development between contradiction.
Facts have proved to only have the mechanical method of employing to construct, improve efficiency of construction, save engineering time and labour, cut the waste, improve workmanship, could pass through to use premixing mortar to reduce construction project integrated cost.Common premixing mortar automatic arc spraying (spray of abbreviation machine) facing plastering construction technology is to make up the plaster a kind of new-type mortar plastering form of construction work of defect of traditional-handwork, is the new direction of following plastering construction development.Machine spray is plastered and has been had abroad more ripe technology, and the domestic research still lacking this technology.Machine spray is plastered and is compared traditional-handwork and plaster and have following advantage: (1) construction quality is good, plaster with basic unit bonding firmly; (2) can significantly improve efficiency, reduce labor intensity; (3) save the spillage of material in work progress.
Automatic arc spraying construction can increase substantially efficiency of construction, reduces labor intensity, and saves the spillage of material in work progress, becomes just gradually the new development trend of following common premixing mortar facing plastering construction technology.At present, domestic common pulp shooting machine major part is imported product, comprises German elephant (putsmeister), Mtec, Pei Fude (PFT) and gondola MIXER.Because domestic and international mortar quality there are differences, domestic common premixing mortar, due to reasons such as self material characteristics, mixture poor fluidities, can not adopt import pulp shooting machine well, and import pulp shooting machine is mainly used in lacquer special type mortar.Domestic pulp shooting machine uses screw pump to carry whitewashing mostly, screw pump inner rubber is is very easily worn and torn and is made service life of screw pump shorter, generally every conveying is whitewashed 100 tons～150 tons just needs to change, expense is higher, now as not in time change, during whitewashing, occur to stop up and easily cause screw pump directly to damage.Builder is limited by cost, and result causes builder to wish to realize mechanized construction, is but limited by and lacks suitable machine spray equipment.Therefore, development machine sandblast slurry industry, will improve mortar performance on the one hand, will actively research and develop on the other hand the machine spray system operation engineering method that is applicable to domestic mortar, and the popularization that machine sandblast is starched is at home played to positive facilitation.
