Embodiment 1

[0042] Preparation of phosphogypsum mortar: it is formed by mixing solid materials and water at a weight ratio of 1000:355. The solid materials include: by weight, 600 parts of phosphogypsum, 300 parts of aggregate, 0.2 parts of redispersible latex powder, and 0.2 parts of foaming agent, 1 part of cellulose ether, 2 parts of water reducing agent, and 1 part of lignosulfonamide salt.

[0043] Impurities such as floating ash, loose matter, oil stains and other impurities on the surface of the base layer of the wall must be cleaned;

[0044] For base treatment, first use phosphogypsum mortar 2-3mm to repair the reserved holes, electrical box grooves, boxes, etc., and proceed to the next process after the slurry is dry.

[0045] Sticking cakes on the wall and punching ribs: the vertical rib spacing is about 1.5m, and the width of the ribs is preferably 10-20mm.

[0046] On the basis of the previous step, paint the above-mentioned phosphogypsum mortar in an all-round way.

Embodiment 2

[0048] Preparation of phosphogypsum mortar: it is formed by mixing solid materials and water at a weight ratio of 1000:410. The solid materials include: by weight, 700 parts of phosphogypsum, 400 parts of aggregate, 1.5 parts of redispersible latex powder, and 0.3 parts of foaming agent, 1.5 parts of cellulose ether, 2 parts of water reducing agent, and 1.5 parts of lignosulfonamide salt.

[0049] Impurities such as floating ash, loose matter, oil stains and other impurities on the surface of the base layer of the wall must be cleaned;

[0050] For base treatment, first use phosphogypsum mortar 2-3mm to repair the reserved holes, electrical box grooves, boxes, etc., and proceed to the next process after the slurry is dry.

[0051] Sticking cakes on the wall and punching ribs: the vertical rib spacing is about 1.5m, and the width of the ribs is preferably 10-20mm.

[0052] On the basis of the previous step, paint the above-mentioned phosphogypsum mortar in an all-round way.

Embodiment 3

Abstract

The invention provides a dry plastering technology. The dry plastering technology comprises the following steps that solid materials and water are blended into ardealite mortar, wherein the solid materials are prepared from, by weight, 600-700 parts of ardealite, 300-400 parts of aggregates, 0.2-1.5 parts of redispersible latex powder, 0.2-0.3 part of a foaming agent, 1-1.5 parts of cellulose ether, 2 parts of a water reducing agent and 1-1.5 parts of a retarder; the ardealite mortar is painted on a base layer to be plastered. The dry plastering technology has the advantages of saving water, time and labor and the like.

Description

technical field [0001] The invention relates to the field of plastering technology, in particular to a dry plastering technology. Background technique [0002] Plastering, commonly known as whitewashing and wall painting, refers to mixing river sand, lime or mortar king, cement, and adding water to form cement mortar, and then plastering the cement mortar on the wall or the ground. [0003] Due to the poor construction performance of the mortar used in the existing plastering process, only wet plastering can be used, that is, bricks and wet walls must be wetted before plastering. This construction method consumes a lot of water, and is time-consuming and laborious. It takes a long drying process. [0004] In view of this, the present invention is proposed. Contents of the invention [0005] The object of the present invention is to provide a dry plastering process, which has the advantages of water saving, time saving and labor saving. [0006] In order to realize the a...
