Refractory plastika do not trap materijal in advance. If the gas is too large, the product will expand and its strength will dew.
Before you want to know about refraktory plastika materijali, you need to know the types of vatrostalna plastika.
Refraktory plastika are podijeljen u različiti materijali tak as glina, visoka glina, aluminij silicij karbid, silicij, silicij, magnesia, etc. The vezi include water glass and phosphoric acid. In terms of actual use, phosphoric acid cement is used relativno frequently, but the vatrostalno plastika kombinirano with fosfat cement must be trapped, and the trapped time should not be be less than 18-24 hours.
Reasons zašto vatrostalna plastika are zarobljeni
The reason why vatrob plastika need to be trapped is that there are certain nečistoće in the raw materials of the plastika. These nečistoće will react with the phosphoric acid binder, and a large amount of gas will be form after the reaction. The gas will expand the inner parts of the plastika, causing The Structure of The material Is loose and its strength will deCrease after Hardening. The purpose of trapping material is to allow the gas to be full discharged after being placed for a period of time. After the gas is ispražnjen or during construction, the lefting binding agent is dodano, so that the plast function can be full usedized.
If it is a a vodeno staklo vezano plastika, a veziv agent can be dodano tijek tijek na licu mjesta izgradnja. At present, due to technological innovation, an extruder is used to extrude refractory plastics into small cubes before use, and are packaged and in plastic vrećice. They can be opened and used during use, so there is no problem of trapped materials. Because during the storage process, the material has been trapped. Ova metoda od proizvodnje ekstruzija je općenito samo korišteno za izvoz proizvoda.
Refractory plastics used in China are not extruded. A part of the binding agent is dodano during the production process, and the material has been capped during transport. When used, it is opened and the lefting binding agent is added for mixing, and it can be used direktno. But it should be noted that the time must be controlled after 18-24} hours. If it is a short-distance transportation, just control the time. Material trapped on site delays labor. If materials are trapped first, there is no need to trap materials on site, which saves time time and meets construction needs.
