Construction technology of refractory castable material 2
Casting
Casting time require:The latest mixted castable materials should be completely casted within twenty minutes
Casting:The mixed castable materials should be pured into grinding tool and vibrating rod inserted in a timely manner by uniformity ,avoid air bubble and the surface is in a slurry
Requirement and control of scene temperature after casting:Before concreting through casting the scene temperature should be remained more than 10℃(10℃-30℃).If the scene temperature is below 10℃ and should take appropriate warming measures, otherwise that will cause slowly smelting and reduce products preformance.
careful treatment In the process of casting, the flowing property has been lost, that is, the condensed pouring material can not be used for water mixing.
Casting materials after ramming should remain natural surface ,which shouldn't use tools for smoothing and without allowing put fine concrete powder on surface for smoothing.
Within the 24hours after constructionand and especially the casting material before hardening enjoin from moving and striking,vibrating otherwise will produce crack and completely damaged.
Maintainance
tools:Polyethylene plastic film bag, straw bag etc.
The temperature and controling of maintaim condition:Maintain temperature after casting is suit for 15℃-35℃,beyond the temperature range,shoulde raise temperature and low temperature,otherwise will reduce products preformance.
maintain:after hardening casting materials must cover the construction surface with polythene film and then cover top with staw bag in order to refuse evaporation of water and advance activation of cement.Within one day after hardening ,no beating,no ramming.Base on hardening case,generally between 24 and 30 hours, may get rid of film and also can do this after 3days. Within 2 days after getting rid of thin film should go on maintainace.Maintenance to polyethylene plastic film and stamped with wet straw bags, maintainance of three days, uncovering plastic film and straw bags to harden the body in the natural air drying day, you can bake.
Baking
The baking is the last important segment in casting processing.For structure of casting materisl is very dense, when baking absolutely forbid to heat up too fast.Otherwise will cause
incident.
The above construction technology is aimed at the vibration type casting material, does not include the self flowing type casting material.
