    The key points are as follows: the problems that may occur in the function of common raw materials of common interior wall putty nsjf-4b rubber powder polymer binder: improve the adhesion, increase the film-forming property and improve the construction performance

    Should be added in accordance with the scientific ratio, strictly in accordance with the manufacturer's ratio of double fly powder (heavy calcium, old powder, heavy calcium carbonate) fillers: increase the covering power, fineness should be appropriate, generally increase the water demand in the 325-400 mesh or increase the amount of the general assembly, affect the bonding strength gypsum powder to increase the hardness and increase the amount of gel, unable to build talc filler: increase covering power, fineness should be appropriate

    Like 325-40 Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively

    The feature of the breathing wall is obvious

    When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity

    It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively

    The feature of the wall that can breathe is obvious

    When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coating House News: the common raw materials of common interior wall putty may have problems in function nsjf-4b rubber powder polymer binder: improve adhesion, increase film-forming property, improve construction performance

    It should be added according to the scientific ratio, strictly in accordance with the manufacturer's ratio of double fly powder (heavy calcium, old powder, heavy calcium carbonate) fillers: increase the covering power, and the fineness should be suitable, generally increase the water requirement in the 325-400 mesh or increase the amount of water, affect the bonding strength, gypsum powder, increase hardness and increase the amount of gel, unable to construct talc powder

    Filler: to increase the covering power, the fineness should be appropriate, generally in 325-400 mesh, to improve the construction of too fine or add too much to increase the water demand, affect the adhesion, the hardness whitening and mildew proof additive whitening and mildew proof increase the cost, generally do not add water to improve the construction performance, so that the rubber powder dissolves and forms a film

    Excessive dosage will reduce the strength, affect the adhesive force, reduce the film-forming property, and make the function of raw materials of water-resistant putty for interior wall become worse during construction

    Nsjf-3b, 6a, 8 rubber powder polymer binder: improve the adhesive force, increase the film-forming property, and improve the construction performance

    The filler of Shuangfei powder (heavy calcium, old powder and heavy calcium carbonate) should be added according to the scientific proportion and strictly according to the proportion of the manufacturer: increase the covering power, and the fineness should be appropriate

    Generally, if it is too fine in 325-400 mesh or too much, it will increase the water demand, and affect the adhesion

    The filler of talcum powder: increase the covering power, and the fineness should be appropriate, generally in 325-400 mesh Increase the water demand, affect the adhesion, reduce the hardness, generally do not add whitening and mildew proof additives, increase the cost, generally do not add light calcium carbonate filler: increase the covering power, the fineness should be appropriate, generally in 325-400 mesh, improve the construction of too fine or add too much, increase the water demand, affect the adhesion, reduce the hardness of water Improve construction performance, make rubber powder dissolve and form film

    Excessive dosage will reduce the strength, affect the adhesive force, reduce the film-forming property, and make the external wall water-resistant putty function worse

    Nsjf-2a, 6b rubber powder polymer binder: improve the adhesive force, increase the film-forming property, and improve the construction performance

    It should be added according to scientific proportion, strictly according to the manufacturer's proportion of black cement (400) white cement (400) black cement (400) white cement (400) with large amount of shrinkage, low amount of cohesion and low strength

    Setting and strength affected by temperature and humidity Shuangfei powder (heavy calcium, old powder, heavy calcium carbonate) filler: increase covering power, with appropriate fineness

    Generally, if it is too fine or too much in 325-400 mesh, it will increase water demand, affect cohesion, increase hardness of ash calcium powder (OK powder, calcium hydroxide powder) and improve water resistance

    Products with large effective content of calcium hydroxide must be used The addition of the gel resulted in no construction

    If the dosage is small, or the effective content of calcium hydroxide is low, the dosage of anti crack additive for exterior wall should be increased to resist vertical flow

    If the anti crack property is too high, it will affect the construction of quartz powder filler: the fineness should be appropriate, and the hardness can be generally increased to 200 meshes

    If the quantity is large, the water demand will be increased, and the adhesion water will be affected to improve the construction performance, so that the rubber powder can be dissolved and filmed

    Too much will reduce the strength, affect the adhesion, reduce the film-forming property, and make the construction worse

    Traditional putty formula: raw material name proportion (%) construction glue 12 talcum powder 25 calcium bicarbonate CaCO3 (old powder) 25 thickener 38 A total of 100

    This putty is easy to manufacture, can be used after opening the package, has very good construction property, and is easy to polish

    This kind of greasy is soft and low in hardness

    Improved traditional putty: raw material name proportion (%) building glue 38 talcum powder 24 white cement 38 total 100 this formula uses talcum powder for easy construction, white cement is used to improve hardness and adhesion, for easy construction and easy grinding and leveling, so the amount of white cement and talcum powder has certain control

    This kind of putty has poor water resistance

    Two component putty: the proportion of raw materials (L), synthetic resin emulsion, 24400 mesh talc powder 30.8, various auxiliaries, 104425 thickeners, 0.56 water, 23.2 white cement, 20 total 100, this putty is easy to be constructed, polished and smoothed, with good adhesion and good durability

    Recommended putty formula: material dosage (%) p.o42.5r ordinary portland cement 18-28 redispersible latex powder 1-5 quartz powder 10-20 325 mesh heavy calcium powder with water retaining agent 0.3-0.4 hydrophobic agent 0.1-0.2 wood fiber 0.2-0.3 other functional additives 0.05-0.6 formula material dosage (%) nsjf-2a rubber powder 1.7-2 white cement (black cement) 35 Shuangfei powder 35 calcareous powder 30 nexus anti cracking additive 1 ~ 1.5 (the formula in this paper is only for reference) the home of coatings is focused on coatings, diatom mud, paint coating, coating process, news information and coating of fire retardant coating, diatom mud, paint coating, coating process, installation and repair knowledge and decoration effect map of fire retardant coating,
