Coating process: production process of putty

Core tips: the following describes the production formula and process of two kinds of putty: Standard formula and technology of interior wall environmental protection putty powder 100 kg of double fly powder and 20 kg of green putty powder for interior wall are evenly stirred It is required to have a whiteness of more than 90 and no impurities Feeding sequence: first, 300kg of heavy calcium; then 20kg of mother material; continue to feed the rest 700kg of heavy calcium Stir for 40min after all Check fineness, sieve and pack (the first three packages should be put back into the mixer to continue mixing and other packages can be packed normally) Standard for environmental protection and water-resistant putty powder for interior wall Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: the following two kinds of putty production formula and process: interior wall environmental protection putty powder standard formula and process calcium (Shuangfei powder) 100kg + interior wall environmental protection putty powder masterbatch bag (20kg) evenly stirred It is required to have a whiteness of more than 90 and no impurities Feeding sequence: first, 300kg of heavy calcium; then 20kg of mother material; continue to feed the rest 700kg of heavy calcium Stir for 40min after all Check fineness, sieve and pack (the first three packages shall be put back to the mixer for further mixing and other normal packaging) the standard formula and process of environmental friendly and water-resistant putty powder for inner wall (double fly powder) 750KG + lime powder 250kg + environmental friendly putty powder for inner wall (6kg) shall be evenly mixed It is required to have a whiteness of more than 90 and no impurities The fineness of grey calcium is above 320 and there is no impurity Feeding sequence: 300kg of heavy calcium, 100kg of grey calcium, 6kg of masterbatch, 300kg of heavy calcium and 100kg of grey calcium Add another 300kg of heavy calcium; add 50kg of gray calcium and continue to add the rest of heavy calcium After mixing for 40min, check the fineness, sieve and pack (the first three packages shall be put back to the mixer for further mixing and other normal packaging) precautions for putty production I sample test: use a strong transparent plastic bag, put 1000g of putty powder that needs to be mixed into the bag, blow the bag up and shake it for more than 5 minutes, and pay attention to no residue on both sides of the grab For example, to make waterproof putty powder with waterproof rubber powder, 250g lime calcium powder, 750g Shuangfei powder and 4g-6g waterproof rubber powder (depending on the quality of local calcium powder) are put into transparent plastic bags, which are airtight and shaken evenly for 5min, then put into containers, add about 400g water (mixed into paste suitable for construction), and then mix for use after 5min 2、 As for the ordinary rubber powder and waterproof rubber powder for the interior wall, generally speaking, the larger the amount is, the higher the bond strength is, the better the workability and water retention are, but too much addition will weaken the leveling property, which can be adjusted by adding about 1% sodium borate 3、 Inner wall ordinary rubber powder reacts with lime calcium powder, white cement and gypsum powder, which can not be mixed, that is to say, it can not be used as waterproof putty powder Therefore, after the production of ordinary putty, if the waterproof putty is to be produced again, it is necessary to remove all the powder left in the feeding machine and mixer before another kind of putty can be produced 4、 The inner wall waterproof rubber powder can not produce ordinary putty because of its high cost 5、 Talcum powder can replace part of Shuangfei powder 6、 The main component of lime calcium powder is Ca (OH) 2 The higher the content is, the greater the hardness is Generally, 15-40% can be added If it is too little, the waterproof effect is poor If too much, it is easy to crack and turn yellow If yellowing can be solved by adding calcium sulfate, if crack resistance is required, paper reinforced fiber can be added to the inner wall, and wood fiber or polypropylene fiber can be added to the outer wall, so that the crack resistance effect can be increased without increasing the cost 7、 Waterproof rubber powder can also be used as putty and gypsum for exterior wall Waterproof rubber powder for exterior wall can produce waterproof putty for exterior wall, and anti crack putty rubber powder can produce flexible putty for exterior wall, thermal insulation mortar, dry mixed mortar tile binder, pointing agent and various dry powder binders 8、 White cement in exterior wall formula can also be replaced by black cement Quartz sand is not only the filling material, but also the anti cracking and thickening effect, increasing the waterproof effect It can be replaced by cement sand instead of quartz powder, wollastonite powder, or calcium bicarbonate powder 9、 Before the first use of the horizontal double screw belt mixer, the gear oil must be added, and the motor rotates in a clockwise direction In the later use, each bearing must be lubricated frequently Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
