Abstract
The invention relates to a novel steam curing method for preparing a washing machine cement counter balance. The method is characterized in that cement, iron ore or iron powdered ore, waste steel pellet and yellow sand are adopted as raw materials, a cement hardener and water are added into the raw materials and mixed into a clinker, later the clinker is poured into moulds, and then the cement counter balance is prepared by steam curing and demoulding. The steam curing is divided into three steps: step one: the time is 1 to 2 hours, and the temperature is kept at 25 to 50 DEG C; step two: the time is 2 to 3 hours, and the temperature is kept at 50 to 80 DEG C; and the step three: the time is 2 to 4 hours, and the temperature is kept at 80 to 120 DEG C. the method has the advantages of shorter preparation period and lower cost.
Description
(1) technical field:
The present invention relates to a kind of balance weight, especially relate to a kind of cement balance block of washing machine and steam protecting method thereof.Belong to washing machine accessory technical field.
(2) background technology:
Balance weight is disposed at top, middle part or the bottom of all kinds of roller washing machines, automatic washing machine inner core, plays the ballast balanced action.Traditional balance weight has the cast iron balance weight and moulds shell balance weight etc.Cast iron balance weight and to mould shell balance weight preparation cost higher.And traditional cement products generally adopts the method for natural curing, and curing cycle is long, needs about 28 days.
(3) summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of manufacturing cycle shorter, lower-cost novel steam curing legal system is equipped with the method for cement balance block of washing machine.
The object of the present invention is achieved like this: a kind of novel steam curing legal system is equipped with the method for cement balance block of washing machine, it is characterized in that it is to adopt cement, iron ore, steel scrap pellet in a shotgun cartridge, yellow ground to make raw material, add cement hardener and water and stir into grog, through pouring into mould, carry out steam curing, the demoulding then and promptly make the cement balance block finished product, wherein said steam curing divides three phases: the phase I: 1～2 hour time, temperature keeps 25～50 ℃, second stage: 2～3 hours time, temperature keeps 50～80 ℃; Phase III: 2～4 hours time, temperature keeps 80～120 ℃.
Method of the present invention has two kinds of prefabrication and pressings:
The preparation process step comprises: batching, stirring, can vibration, steam curing and the demoulding,
Batching---take by weighing cement, iron ore, steel scrap pellet in a shotgun cartridge, yellow ground by proportioning.
Stir---in mixer, put into an amount of water earlier, put into ore, steel scrap pellet in a shotgun cartridge, yellow ground then, stir, put into cement again, put into cement hardener at last, evenly stir and make grog while pour into.
The can vibration---the mould that will prepare balance weight is placed on the shake table, pours into the small part grog in each mould earlier, vibrates after 1～5 second, again grog is filled mould, vibrates 1～8 minute then, limit vibration this moment, and the limit is reinforced till filling the mould plane.
Steam curing---the mould that will fill grog is put into vaporium, carries out steam curing.
Demoulding---after the steam curing time arrived, the mould that gets loose got the cement balance block manufactured goods.
Wherein the weight ratio of cement balance block each component is:
Cement 17%～22%
Iron ore 50%～60%
Steel scrap pellet in a shotgun cartridge 5%～10%
Yellow ground 10～20%
Cement hardener 0.7～0.9%
Surplus is a water
The total amount sum of each component is 100%.
The concrete processing step of pressing comprises: prepare burden, stir, weigh compacting and steam curing:
Batching---take by weighing cement, Iron Ore Powder, steel scrap pellet in a shotgun cartridge, yellow ground by proportioning.
Stir---earlier siccative is stirred, the water that slowly will be added with curing agent is then poured the back into and is stirred and made grog in 8～15 minutes, and it is even to reach moisture distribution, mixing blowing fully again.
Weighing, compacting---weight weighs up grog in accordance with regulations, and a lay part is evenly paved to mold cavity, smooth then reinforcing bar or the skeleton put into, pour the remaining part grog again into, pave, carry out the matched moulds compacting, take out goods after the die sinking reposefully with hand, turn over or hold in both hands to flat board, remove burr, wait to steam.
Steam curing---goods are put into vaporium, carry out steam curing.
Wherein the weight ratio of cement balance block each component is:
Cement 20%～30%
Iron Ore Powder 50%～60%
Steel scrap pellet in a shotgun cartridge 10%～15%
Yellow ground 5～10%
Cement hardener 0.3～0.5%
Surplus is a water
The total amount sum of each component is 100%.
The cement balance block that adopts the present invention to make has the cycle short (4～8 hours), and shipment is fast, efficient height, characteristics such as intensity height.
