Plastering gypsum formula

Abstract

The invention discloses a plastering gypsum formula, which comprises the following materials in weight percent: desulfurized gypsum and calcium carbonate (with a ratio of 8:2), 5 percent of fine sand screened out by a 0.8mm mesh screen, 1.8 thousandths of hydroxypropyl methylcellulose, 1 thousandth of polyvinyl alcohol, 1 thousandth of lignocellulose, 3 thousandths of gypsum retarder, 0.15 thousandths of guar gum and 2 thousandths of slaked lime, all of which are mixed uniformly. The plastering gypsum produced by the formula is convenient and fast in construction, gelates automatically, has a unique self-breathing function, is colorless, odorless, non-radioactive and noise-absorbing, does not shrink and crack, can meet the function requirements of building partitions, is economical and practical, is an ideal choice for high-rise and middle and low rise building walls and decoration and fitment, and has the advantages of high strength, rapid hardening, fire protection, earthquake resistance, heat resistance, heat insulation, sound insulation, high cementation, no empty drum, construction success in one time, convenient operation and the like; not only project quality is improved but also project period is shortened, and better comprehensive benefits are obtained.

Description

technical field [0001] The invention relates to a formula for plastering plaster. Background technique [0002] Gypsum plaster is mainly used for plastering various walls and ceilings in buildings. According to the purpose, it can be divided into surface plaster plaster, bottom plaster plaster and insulation plaster plaster. Among them: the plaster plaster on the surface usually does not contain aggregates and has high strength, and is used for plastering plaster or the outermost layer of plastering materials on other substrates; the plaster plaster on the bottom layer usually contains aggregates and is used for leveling the base; the insulation layer Plaster plaster has good thermal insulation properties and usually contains light aggregates and is used for internal insulation of building exterior walls.
