Description
ваппе покрыти в процессе сушкп и улучшает адгезию покрыти к керамике.vappa coating in the drying process and improves the adhesion of the coating to ceramics.
В процессе обжпга происходит взапмодействпе белитового шлама с кварцевым песком с образоваиием волластоппта по схеме.In the process of obzhpga occurs in the run of belite sludge with quartz sand with the formation of wollastroppt according to the scheme.
2CaO.SiOa+SiO,-v2(CaO SiO.,).2CaO.SiOa + SiO, -v2 (CaO SiO.,).
Вол.частонитVol.chastonit
Присутствие в шихте 6-9% жидкого стекла обеспечивает спижеиие темиературы об)азовани волластоиита до 930-980°С.The presence of 6–9% liquid glass in the charge ensures the reduction of the temperature of wollastoiite to 930–980 ° C.
Волластонит - кристаллическое соедииеипе характеризуетс высокой механической ирочиостыо и до.;1говечност111о. Кроме того, он придает покрытию белую окраску. При использовании глии с высоким содержанием железа иокрытие приобретает кремовую окраску.Wollastonite is a crystalline compound that is characterized by high mechanical irochiosta and up to.; In addition, it gives the coating a white color. When using glia with a high content of iron, the covering acquires a creamy color.
Такой состав обеспечивает возможпость регулировать весь комплекс свойств покрытп па различных стади х изготовлени изделий .Such a composition makes it possible to regulate the entire complex of properties of the coatings at various stages of manufacturing products.
Шихту иеред иаиесеннем покрыти готов т совместиым мокрым помолом белитового шлама, кварцевого песка и глинистого комиопеита до прохождени через сито № 0063 более 95%. Затем нолучеииую смесь, жидкое стекло и метилцеллюлозу дозируют в мешалку и добавл ют воду с температурой выше 20°С до получени при перемешивании сусиеизии с иеобходимой плотностью {1,54-1,78 г/смз).The mixture was prepared by the combined wet milling of belite sludge, quartz sand and clay komiopeit prior to passing through sieve No. 0063 more than 95%. Then the batch mixture, water glass and methylcellulose are metered into the mixer and water with a temperature above 20 ° C is added until the mixture is mixed with the necessary density {1.54-1.78 g / cm3).
В лабораторных услови х ио описаииому способу готов т шихту дл лицевого покрыти керамики. Состав предлагаемой шихты нриведен в табл. 1.Under laboratory conditions, a mixture is prepared for the front coating of ceramics. The composition of the proposed mixture is shown in Table. one.
Таблица 1Table 1
Покрытие ианос т на иоверхность образцов-кубиков пластического формовани размером 50x50X50 мм и образцов-цплиидров иолусухого прессовани диаметром 50 мм слоем в 2,0 мм, 1,0 мм и 0,5 мм.The coating of the coating on the surface of the plastic molding cubes was 50x50x50 mm in size and the specimens of mold and medium dry molding 50 mm in diameter with a layer of 2.0 mm, 1.0 mm and 0.5 mm.
Затем образцы сушат до посто нного веса ири 90-95°С и обжигают при 950°С, 975°С и 1000°С в течение 3 ч.Then the samples are dried to a constant weight of 90–95 ° C and burned at 950 ° C, 975 ° C, and 1000 ° C for 3 hours.
После обжига образцы испытаны на морозостойкость по стаидартпой методике.After firing, the samples were tested for frost resistance according to a standardized technique.
Характеристика и физико-механические показатели покрытий образцов представлены в табл. 2.Characteristics and physico-mechanical properties of the coatings of the samples are presented in table. 2
