Migumisiro:

Basa guru re “Health Certificate” nderokuona uye kuratidza kuti zviri mukati mesimbi inorema muzvigadzirwa zvegirazi, ceramics, zvirongo zvekenduru uye zvimwe midziyo zviri mukati mehuwandu husina ngozi kumuviri wemunhu.

Nezve girazi bhodhoro uye girazi bhodhoro:

Chinhu chikuru chegirazi ndeye silica, iyo yakaverengerwa mune rondedzero yezvakaregererwa zvigadzirwa.

Nezve chirongo checeramic:

Mushure mokunge ceramic yaputsika, inogona kuoneka zvakajeka kuti chimiro chemukati chine mitsara mitatu, mukati-kati ivhu revhu, pakati ndiro ruvara rwemavara, uye kunze ndeye silica crystal layer. iyo silica crystalline layer seyakajeka ruvara.
Iyo yepamusoro inosangana nechikafu inowanzofukidzwa ne glaze, kureva kuti, crystalline layer ye silica inosangana nechikafu. Naizvozvo, mumamiriro ezvinhu akajairwa, zviri mukati mesimbi inorema muruvara glaze pamusoro peporcelain zvinosvika pachiyero.
Nekuti mavara akasiyana eruvara glaze ane zvikamu zvakasiyana.
Semuenzaniso, dzvuku glaze ine chikamu chepamusoro chesimbi, dema glaze ine chikamu chepamusoro checobalt element, uye chena glaze ine chikamu chepamusoro chepickaxe nezvinhu zvealuminium, kunyanya pamusoro pematte porcelain haina pachena. silica makristasi. Kana iyo layer yabviswa, heavy metal test inofanirwa kuitwa zvakare kuratidza kuti heavy metal yemukati meruvara glaze haina chakaipa kumuviri wemunhu.

Mamirire ezvinhu:
