Silicon Dioxide: Chinhu Chinoshandiswa Muindasitiri Chine Zvinangwa Zvakawanda
Minda mikuru yekushandisa
Zvinhu Zvine Chinangwa Chakawanda Zvinosangana Nezvinodiwa Zvakasiyana-siyana
1. Kugadzira Magirazi
Silicon dioxide ndeimwe yezvinhu zvikuru zvekugadzira magirazi. Kana ikanyungudutswa pakupisa kwakanyanya, inoumba girazi rine kujeka kwakanaka uye simba remuchina. Nekugadzirisa huwandu hwesilicon dioxide uye huwandu hwezvimwe zvikamu, mhando dzakasiyana dzegirazi dzinogona kugadzirwa, dzakadai segirazi rakatsetseka, girazi re optical, uye girazi rakakosha. Magirazi aya anoshandiswa zvakanyanya mukuvaka, mota, zvemagetsi, uye zvishandiso zve optical.
2. Kugadzirwa kweCeramic
Muindasitiri yezvedongo, silicon dioxide chinhu chakakosha. Inogona kuvandudza hunhu hwemakanika uye kugadzikana kwekupisa kwezvedongo, kuwedzera kuomarara kwazvo uye kuramba kupfeka, uye zvakare kudzora tembiricha yekutsva kwezvedongo, zvichiita kuti zviumbwe zviri nani pakupisa kwakanyanya. Zvigadzirwa zvezedongo zvinoshandiswa zvakanyanya mukushongedza zvivakwa, zvikamu zvemagetsi, uye michina yeindasitiri.
3. Maindasitiri eRabha nePurasitiki
Silicon dioxide inowanzo shandiswa semuchina wekuzadza nekusimbisa simba mumaindasitiri erabha nepurasitiki. Inogona kuvandudza simba remakanika, kuramba kupfeka, uye kuramba kupisa kwerabha nemapurasitiki, ukuwo ichivandudzawo hunhu hwavo hwekugadzirisa. Semuenzaniso, mukugadzira matai, silicon dioxide inogona kuwedzera kubata nekuramba kupfeka kwematayi, zvichiwedzera hupenyu hwavo hwekushanda. Pamusoro pezvo, silicon dioxide inogona kushandiswa kugadzira mapurasitiki anoshanda zvakanyanya, ayo anoshandiswa zvakanyanya mumotokari, muchadenga, uye mumagetsi.
4. Indasitiri yeCoatings and Pendi
Silicon dioxide ine basa rakakosha muindasitiri yekupenda nekugadzira pendi. Inogona kushandiswa semuchina wekuzadza nekugadzira pigment kuti ivandudze simba rekufukidza uye kunamira kwekupenda, ukuwo ichivandudza kuenzana kwayo uye kupenya kwayo. Uyezve, silicon dioxide inogona kuwedzera kusimba kwemamiriro ekunze uye kuramba ngura kwemakemikari kwekupenda, zvichiita kuti irambe ichishanda zvakanaka munzvimbo dzakaoma. Zvigadzirwa zvekupenda zvinoshandiswa zvakanyanya mukuvaka, mota, uye michina yeindasitiri.
5. Mamwe Mashandisirwo
Silicon dioxide inogona kushandiswawo mune dzimwe nzvimbo. Semuenzaniso, muindasitiri yezvemagetsi, inogona kushandiswa sechikamu chekudzivirira kupisa kwezvinhu zve semiconductor; muindasitiri yezvikafu, inogona kushandiswa semushonga unodzivirira kuvharika kweganda uye semushonga unosimbisa; uye muindasitiri yemishonga, inogona kushandiswa semushonga wekuzadza uye mushonga unodzorwa wemapiritsi.

Kurongedza uye Kuchengeta
Silicon dioxide inoiswa mumidziyo yakavharwa kuitira kuti irambe yakaoma uye isina kusvibiswa panguva yekutakura nekuchengetera. Inofanira kuchengetwa munzvimbo inotonhorera, yakaoma, uye ine mhepo inofema zvakanaka, kure nezvinhu zvine simba zvinoparadza zvakaita seacids nealkalis. Panguva yekuchengetera, kutarisirwa kunofanirwa kupihwa kudzivirira hunyoro uye kudzivirira kupisa kwakanyanya kuti chigadzirwa chigare chakachengeteka uye chigare chakasimba.
