Isitini somlilo esingasindi sisetshenziswa kakhulu ohlelweni lokufakwa kweziko. Ukusetshenziswa kwesitini somlilo esingasindi kufinyelele imiphumela ethile yokonga amandla kanye nokuvikela imvelo embonini yokushisa okuphezulu.
Isitini somlilo esiyisisindo esingasindi siyinto efakwayo enobuningi obuncane, i-porosity ephezulu, kanye ne-thermal conductivity ephansi. Izici zayo zokuminyana okuphansi kanye ne-thermal conductivity ephansi ziyenza ingakwazi ukubuyiseleka eziko ezimbonini.
Inqubo yokukhiqiza yeisitini somlilo esingasindi
1. Kala izinto ezingavuthiwe ngokwesilinganiso esidingekayo, gaya impahla ngayinye ibe yimpushana. Faka amanzi esihlabathini se-silica ukwenza i-slurry futhi uyishise ngaphambili ekushiseni kwama-45-50 ℃;
2. Faka izinto zokusetshenziswa ezisele ku-slurry bese ugoqa. Ngemuva kokuxuba okuphelele, uthele i-slurry ehlanganisiwe esikhunjini bese uyishisa ku-65-70 ° C ukuze igwebu. Isamba esinamagwebu sikhulu kunama-40% yenani eliphelele. Ngemuva kokukhipha amagwebu, yigcine ku-40 ° C amahora ama-2.
3. Ngemva kokuma unganyakazi, ngena egunjini elishisayo ukuze ushise, ngokucindezela okushisayo okungu-1.2MPa, izinga lokushisa elishisayo elingu-190 ℃, kanye nesikhathi esishisayo samahora angu-9;
4. Izinga lokushisa eliphezulu sintering, izinga lokushisa 800 ℃.
