Embodiment 1

[0018] Materials and ratio of component A: 325 mesh heavy calcium carbonate 5KG, stone sand with particle size 0.2-0.8mm 14.9KG, old powder 5kg, polyvinyl alcohol powder 0.25kg, cement retarder 0.13KG, cement primer Gas agent 0.02KG, cement enhancer 0.1kg, methyl cellulose ether 0.1KG, after mixing, pack in plastic bags for later use, and the shelf life is more than 12 months.

[0019] The material and ratio of component B: 42.5 ordinary Portland cement 6.5KG, packed in paper sealed bag, the shelf life is three months. The dry powder mortar can be used by mixing components A and B with water during the shelf life. If the storage period of component B exceeds three months, it needs to be tested. Those who pass the test can continue to use it, and those who fail must replace the component B. Component A material will not be wasted.

Embodiment 2

[0021] Materials and ratio of component A: 13.85KG sand with particle size of 0.2-1mm, MC0.1KG, 0.15KG redispersible latex powder, 5.8KG heavy calcium carbonate, 0.05KG cement water reducing agent, 0.05 cement early strength agent kg mixed and packed in plastic bags, the shelf life is 12 months.

[0022] Materials and ratio of component B: 5.5KG slag Portland cement is packaged in paper bags, 1KG calcium hydroxide is packaged in small bags, and then put into a 5.5KG cement bag and sealed.

[0023] After components A and B are packaged separately, put them together in a 20KG component A packaging bag. When using within the shelf life, just mix components A and B and reconcile them with water. If the shelf life of component B has expired, then Component B must be tested and qualified before it can be used, otherwise it should be replaced.

Embodiment 3

[0025] The materials and ratio of component A: 6KG grade 2 fly ash, 5KG wollastonite powder, 7.6KG fine sand, 0.1KG cellulose ether, 1.2KG redispersible latex powder, 0.1KG lignocellulose, after mixing evenly, press each The 20KG weight portion is sealed and packaged for use, and the storage shelf life is 12 months.

[0026] The material and ratio of component B: 42.5 Portland cement 5KG, packed in a sealed bag for storage, the shelf life is three months. When using within three months, mix components A and B with clean water. If component B exceeds the storage period of 3 months, it should be re-tested, and the unqualified ones should be replaced with qualified ones for reuse. .

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 [0001] The invention relates to building material technology, in particular to packing dry powder mortar in groups. Background technique [0002] Dry-mixed mortar, also known as dry-mixed mortar, dry-mixed mortar, and dry-mixed building materials, originated in European countries in the 1950s and 1960s. It is a building bonding material that is composed of fillers, pigments, additives and inorganic coagulating materials such as cement, gypsum, and lime after being mixed evenly in the factory and sent to the construction site. Compared with the on-site mortar process, it has the advantages of low labor intensity of construction workers, high product quality stability, favorable quality management, and reduction of dust flying. It has been widely valued and there is huge room for development. But the production method of this dry powder mortar is: ① the filler pigment, auxiliary agent, cement, gypsum, lime, weighed in proportion and mixed together for packagin...
