Kushandiswa
Ethyl silicate (TEOS) imvura isina ruvara, inonyanya kushandiswa semachira anodzivirira kupisa, machira anodzivirira makemikari, machira ekubatanidza silane, ma organic synthesis intermediates, uye senzira yekutanga kwemafirimu e chemical vapor deposition (CVD)SiO2 mumunda we semiconductor, nezvimwewo. Nzvimbo yekunyunguduka ye ethyl silicate i -77℃, uye nzvimbo yayo yekufashaira i 165.5℃. Inonyunguduka zvishoma mumvura uye inonyunguduka mu ethanol ne ether.
Inoshandiswa sechinhu chinodzivirira kupisa muindasitiri yemagetsi uye zvakare semushonga wekugadzirisa magirazi egirazi uye coagulant
Inoshandiswa pakukanda nemazvo sechinobatanidza zvinhu zvejecha; Nzvimbo yesimbi inobatwa ne ethyl silicate vapor inogona kudzivirira ngura nemvura. Ethyl silicate inogona kushandiswa kunyudza pamusoro pesimbi nesilicon, uye kurapa girazi re optical kunogona kuwedzera kufambiswa kwaro kwechiedza. Upfu hwakatsetseka hwe silica hunogadzirwa mushure mekunyudzwa kwemvura yakakwana hunogona kushandiswa kugadzira phosphors. Ethyl silicate ndiyo yakagadzirwa nemafuta e silicone. Ethyl silicate inogonawo kushandiswa kugadzira machira anodzivirira kupisa uye anodzivirira makemikari. MuJapan, 90% ye ethyl silicate inoshandiswa sehwaro hwemachira anodzivirira ngura (pendi ine zinc yakawanda).
Inonyanya kushandiswa muzvipfeko zvinodzivirira makemikari uye zvinodzivirira kupisa, zvinonyungudutsa zvesilicone uye zvinonamira zvakanyatsonaka. Mushure me hydrolysis yakakwana, upfu hwakatsetseka hwesilicon dioxide hunogadzirwa, hunoshandiswa kugadzira phosphors uye hunogona kushandiswawo se reagent yemakemikari.
Tetraethoxysilane inonyanya kushandiswa mugirazi remagetsi, machira anodzivirira makemikari, machira anodzivirira kupisa uye zvinonamira. Kugadziriswa kwezvipfeko zvinodzivirira ngura. Chinhu chinobatanidza, chinosunga, chinobvisa mvura mumuviri; Kugadzirwa kwemaskeleton emagetsi uye silica yemhando yepamusoro yakachena.
Ethyl orthosilicate inonyanya kushandiswa mugirazi re optical, machira anodzivirira makemikari, machira anodzivirira kupisa uye manamati. Kugadziriswa kwezvipfeko zvinodzivirira ngura. Chinhu chinobatanidza, chinosunga, chinobvisa mvura mumuviri; Kugadzirwa kwema skeleton e catalyst uye high-purity ultrafine silica.
Zvinhu zvinodzivirira ngura zveindasitiri yemagetsi, machira, magirazi ekurapa, macoagulants, organic synthesis, solvents yekugadzira organosilicon
Muchikamu chakabatanidzwa chinoumba H+-magadiite, chinoita sechinopindirana nedodecylamine pakudzidza girazi rinoshandisa simbi yakasanganiswa. Inowanzoshandiswa senzira yekutanga mukugadzira majeli akaoma.
Kurongedza uye Kutumira
Kurongedza: 200kg zvichienderana nezvinodiwa nevatengi.
Kutumirwa: ndekwemakemikari akajairika uye kunogona kutumirwa nechitima, gungwa nemhepo.
Stock: vane 500MTs safety stock
Chengeta uye chengeta
Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
