A ceramic toilet for dealing with excrement is necessary in every home and bathroom. People in different countries may use different types of toilets. European families prefer two-piece (close-coupled) water closet, usually of washdown flushing featured with bigger sized trapway. The washdown two-piece toilets are usually flushed through water gravity. Outer diameter of the trayway is around 100mm. American families prefer one-piece toilet, usually of siphonic flushing featured with smaller sized trapway. The siphonic toilets are usually flushed through siohon function of the tube. Outer diameter of the trapway will be smaller than washdown toilet.
There are also many other toilet variants such as wall-hung toilet, which usually comes with a concealed cistern and metal frame. Back-to-Wall toilets are also very popular in Europe. It makes the bathroom very modern and clean with the concealed installation system.
But how are ceramic toilets made in Longcreamic? What’s the process? Here we’ll give an overview.
Raw Material Preparation
Toilet bowls and cisterns are made from a special clay called vitreous china, which is a composite raw material. It’s a mix of several kinds of clay, called ball clay and china clay, silica, and a fluxing agent. Quartz and feldspar are also commonly used.. Hard material as quartz and feldspar usually act as bones of a toilet body, it forms the main structure of the toilet. Ball clays and china clay act as shaping material, which helps to form the shape of the toilet.
The raw material will be mixed according to Longcreamic’s specific formula and proportion. They’ll be mixed and grinded in big ball mills into slurry slips. Workers at the toilet factory will then first thin the slurry slip to a watery consistency. Then, they will feed it through very fine screens in order to sieve out any impurities. A big magnet may also be used to remove the iron dust. (the iron dust easily bring defects on ceramic surface) The purified slip is thickened again, and pumped into storage tanks in preparation for use in toilet casting. (The purified will be stored there for several days so that it can be more stable. Duing the process, QC from Longcreamic will keep a dynamic monitoring of the clay. They’ll take samples and test the chemical and physical performance according to our quality standard.
