Description
отверждени , а также ее газотворна способность . При содержании кремнийорганической смолы ниже нижнего предела прочность и термозстойчивость оболочковых форм станов тс недостаточными.curing, as well as its gas-making ability. When the content of the silicone resin is below the lower limit, the strength and thermal stability of the shell forms become insufficient.
В качестве органического легколетучего растворител предпочтительно использование этанола технического.As an organic volatile solvent, it is preferable to use technical ethanol.
В качестве огнеупорного наполнител нар ду с кварцевыми иесками возможно применение цирконовых несков и других нанолнителей повышенной огнеупорности.Zircon nesk and other nanofillers of enhanced refractoriness can be used as a refractory filler along with quartz titanium.
Приготовление смеси может осуществл тьс двум известными способами: холодным и гор чим плакированием.The mixture can be prepared by two known methods: cold and hot cladding.
При холодном плакировании огнеупорныйWhen cold cladding refractory
наполнитель тщательно иеремешивают с порошком кремнийорганической смолы и, не прекраща неремещивани , в смесь ввод т растворитель, затем смесь продувают холодным воздухом дл удаленн растворител .The filler is thoroughly mixed with the powder of silicone resin and, without stopping dislocation, the solvent is introduced into the mixture, then the mixture is blown with cold air to remove the solvent.
При гор чем плакировании к огнеупорному наполнителю, иагретому до 160-180°С, добавл ют иорошок кремнийорганической смолы , котора при перемешивании покрывает смол ной пленкой зерна песка.During hot cladding, a silicone silicone powder is added to the refractory filler, heated to 160-180 ° C, which, with stirring, covers the sand grain with a resin film.
Составы и свойства предлагаемых смесей, приготовленных описанным способом холодного плакировани (№№ 1-4), и известной смеси (№ 5) приведены в табл. 1 и 2.The compositions and properties of the proposed mixtures prepared by the described method of cold cladding (Nos. 1-4) and the known mixture (No. 5) are listed in Table. 1 and 2.
Отработанна смесь легко выбиваетс из отливок.The spent mixture is easily knocked out of the castings.
Таблица 1Table 1
Таким образом, предложенна плакированна смесь обеспечивает получение оболочковых форм и стержней с иовышенной термоустойчивостью и пониженной газотвориой способностью , что позвол ет существенно повысить качество стальных и чугунных отливок.Thus, the proposed clad mixture provides shell molds and cores with improved thermal stability and low gas production capacity, which significantly improves the quality of steel and cast iron castings.
