Description
Обмазки, примен ющиес в производстве прецизионного лить по восковым модел м, имеют педостаткп, состо и1.пе в том, что во врем сушки и прокаливаии форм на обмазке часто образуютс треИ ;ины , из-за чего часть отливок отходит в брак. Кроме того, они требуют длительной сушки и прокаливаии форм и имеют недостаточную огнеупорность.The coatings used in the production of precision casting on wax models have a pedostatp, consisting in the fact that during the drying and calcination of the molds on the coating there are often three kinds of castings, which causes part of the castings to be discarded. In addition, they require prolonged drying and calcination of forms and have insufficient refractoriness.
Применением обмазки предлагаемого состава эти недостатки можно в значительной мере устранить.The application of the coating of the proposed composition of these shortcomings can be largely eliminated.
Дл повышени огнеупорности обмазки пудра и присыпка ее делаютс из плавленого кварца (отходы стекольного производства), а основным св зующим компонентом служит эфир ортокремнпевой кислоты.To increase the refractoriness of the coating, the powder and its powder are made of fused quartz (glass production waste), and the main binder component is the orthosilicic acid ester.
Применение плавленого кварца R значительной степени .уменьшает объемное изменение формы ири нагреве ее в ироцессе лить , в результате чего иредотвращаетс образование трещин. Высока огнеупорность обмазки уменьшает образование нагара обмазки.The use of fused quartz R significantly reduces the volumetric change in the shape of the irri to heat it during its pouring process, as a result of which cracking is prevented. High refractoriness of the coating reduces the formation of carbon coating.
Продолжительность прокаливани форм в результате применени обмазки предлагаемого состава может быть сокран1,ена в несколько раз.The duration of the calcination of the forms as a result of the application of the coating of the proposed composition can be reduced several times.
