Abstract
The invention relates to a building material technology, in particular to a dry powder mortar packaged by composition separation, which is formed by classified packaging according to quality guarantee periods of material compositions, wherein a composition A consists of a filler, a pigment and an auxiliary agent the quality guarantee periods of which reach between 12 and 24 months; and a composition B consists of a hydraulic inorganic solidification material which only has three months of quality guarantee period. The dry powder mortar packaged by the composition separation has the advantage that the composition A has long storage and quality guarantee periods, and the waste of the filler, the pigment and the auxiliary agent is overcome and reduced; the important keeping and storage are convenient to the composition B with the short quality guarantee period, and the composition B can be extracted from unused mortar for hurry use or a novel composition B is replaced into the unused mortar when the quality guarantee period approaches to avoid engineering hidden trouble and energy waste; and dry powder mortar production enterprises can only produce the composition A to supply construction organizations or dealers, and the composition B adopts the nearby configuration, thus the quality of products can be ensured, and mass transportation and turnover cost can be reduced.
Description
Technical field
The present invention relates to building material technology, particularly dry powder mortar packaged in grouping manner.
Background technology
Dry-mix claims dry-mixed mortar, dry-mixed mortar, dry powder building materials again, originates from the European countries in 50-60 age in 20th century.It is to pack after being mixed in factory by inorganic coagulated materials such as filler, pigment, auxiliary agent and cement, gypsum, lime to deliver to the building site, only need add water in the building site and mix the building class matrix material that can use, cooperate mortar technology to compare with traditional scene, have that builder's labour intensity is low, constant product quality height, favourable quality control, reduce superiority such as dust from flying, paid attention to widely, existed huge development space.But the production method of this dry-mix is: 1. with filler pigments, auxiliary agent, cement, gypsum, lime, mix to pack to sell after the weighing and use in proportion; 2. as application number be: the 200710037388.Z disclosed method, material mixing such as cement, gypsum, lime and filler, auxiliary agent, foaming polystyrene particle together as the A component, are sold to pack the back by the quartz sand of 40 mesh sieves as the B component.But owing to play cement, gypsum, the lime of main coagulation in the dry-mix is the product of quality guaranteed period very short (being generally 40 days to three months), the shelf life of products of the derived product dry-mix of making is retrained by it, can not surpass the quality guarantee period of cement, gypsum, lime.China is vast in territory in addition, trade in all directions, transportation, the time-consuming length of the field of circulationization, the use that is nowhere near of three months quality guaranteed period, existence for enterprise, a lot of enterprises violate the principles of science the dry-mix quality guaranteed period of producing are marked as six months even 1 year, even but deliberately the quality guaranteed period is prolonged, yet having a lot of expired products occurs, product is used for engineering if these exceed the time limit, to cause a hidden trouble to construction quality, if not only cause very big energy dissipation as scrap handling, also environment is damaged, therefore must be improved.
Summary of the invention
The object of the present invention is to provide a kind of the solution because the hidden dangers in project that dry-mix quality guaranteed period problem causes and avoid the wasting technical scheme of product obsolescence.
The present invention solves by following method:
Can reach filler, pigment, the auxiliary agent of 12-24 month quality guaranteed period, can reach 12-24 month A component as the quality guaranteed period and pack standby by mixing after the proportioning weighing, the inorganic matrix material that solidifies is crossed the title packing respectively by the weight of design, as the quality guaranteed period is that trimestral B component is standby, during use A, B component water is in harmonious proportion and gets final product.In the dry-mix of the present invention, the material quality guaranteed period that the A component adopts all should select to reach 12-24 months product, and the B component must select to reach trimestral cement, gypsum and lime quality guarantee period.Reply B component was checked again when the shelf lives of dry-mix reached three months, can continue when performance is qualified to use, otherwise should change the B component, and the A component that accounts for main weight part in dry-mix is unaffected.Wherein:
Described filler is by sand, ore powder, lime carbonate, pigment, particle diameter 0.01-10mm pearlstone, the polyphenyl foam particle, flyash, slag, slag, the kiln ash, phosphorus slag, the mixture of one or more in the vermiculite, described pigment is inanimate matter pigment, the mixture of one or more in the organic synthesis pigment is formed, described auxiliary agent is a cement setting retarder, cement water reducing agent, cement early strength agent, the cement air entrapment agent, cement intensifier, cement modifier, hydrophobizing agent, defoamer, softening agent, the anti-dimension of towing, polyvinyl alcohol, Ployethylene Wax, redispersable latex powder, dispersion agent, thickening material, ether of cellulose, one or more the mixture in the powder ether is decided in modification;
The inorganic solidification material of the hydraulicity in the described B component is one or more the mixture in portland-type cement, sulphur aluminic acid class cement, ferro-aluminate class cement, aluminate class cement, gypsum, the lime.
Wherein, be preferably portland-type cement in the B component, comprise silicate cement, ordinary Portland cement, Portland blast, Portland pozzolana cement and Portland fly ash cement, composite Portland cement, limestone portland cement, dross slag cement, road silicate cement, masonry cement, form from stress silicon acid salt cement, phosphate slag portland cement and their mixture thereof.
Described gypsum is one or more the mixture in the plaster of paris, semi-hydrated gypsum, the dihydrate gypsum.
Described lime is formed by one or more the mixture in unslaked lime, slaked lime, the calcium hydroxide.
On the basis of such scheme, the A component is single packaged, perhaps, presses the component portion package.That is: the quality guaranteed period can be reached 12-24 month filler, pigment, auxiliary agent by the proportioning weighing after packing respectively, as the A component, the quality guaranteed period is 24 months.
On the basis of such scheme, in the B component,, perhaps, form by the component portioning by single packaged composition.That is: the quality guaranteed period can only be reached trimestral inorganic coagulant, pack respectively after claiming excessively respectively as cement, gypsum, lime, as the B component.
The superiority of dry powder mortar packaged in grouping manner is:
1., performance A component stores quality guaranteed period limit for length's advantage, overcomes and reduce the waste of filler, pigment, auxiliary agent;
2., be convenient to short B component of quality guaranteed period is carried out the emphasis keeping, stores, when closing on the quality guaranteed period, can from untapped mortar, put forward promptly to use or change to new B component, in order to avoid cause hidden dangers in project and energy dissipation;
3., cement, gypsum, lime product all parts of the country all can be purchased, and carry out unified national standard, dry powder mortar production enterprises can only be produced A component supply unit in charge of construction or dealer, the B component can be by various places dealer or unit in charge of construction's configuration nearby voluntarily, not only can guarantee quality product but also can reduce a large amount of transportations and the turnover cost, thereby alleviation is built, unit in charge of construction dislikes the existing dry-mix cost of use too high, and the contradiction that is difficult to promote has very huge economic benefit and social benefit.
