Ethyl silicate: Chinhu chemashiripiti mumunda wemaindasitiri

Munyika yakakura yezvinhu zvemaindasitiri, ethyl silicate inoonekwa senyeredzi inopenya, ichiunza hunyanzvi nebudiriro kumaindasitiri akawanda nehunyanzvi hwayo hwakasiyana uye mashandisirwo akasiyana-siyana. Ethyl silicate imvura isina ruvara uye inoonekera patembiricha yemumba uye ine hwema hwakasiyana. Munzvimbo isina mvura, inogara yakasimba uye yakavimbika. Zvisinei, kana yangosangana nemvura, inoora zvine hungwaru kuita ethanol ne silicic acid, uye zvishoma nezvishoma inova turbid mumhepo ine hunyoro. Hunhu uhwu hunoshamisa hunoibvumira kutamba basa rakakosha mukuita kwakawanda kwemakemikari uye kugadzirira zvinhu. Inonyungudika nyore nyore muzvinhu zvinonyungudutsa zvakaita sealcohol ne ether, ine molecular formula ye, melting point yakaderera se, uye boiling point ye. Kubva pamaonero enzira yekugadzira, inowanikwa nekungwarira ne distillation mushure mekudyidzana pakati pesilicon tetrachloride ne anhydrous ethanol. Maitiro aya ekugadzirira akaomarara anovimbisa mhando yepamusoro uye kugadzikana kwe ethyl silicate. Mukushandiswa kwakakosha, ethyl silicate inogona kuonekwa se "jack yekutengeserana kwese". Mumunda we coatings, ndiyo chinhu chikuru chekugadzira coatings inodzivirira kupisa uye inodzivirira makemikari. MuJapan, kusvika ku90% ye ethyl silicate inoshandiswa sehwaro hwezvinhu zvekudzivirira ngura (pendi ine zinc yakawanda). Mushure mekupfapfaidza, mapoka ealkoxy ari muchimiro chawo chemolecular anogona kutora hunyoro kubva mumhepo uye kuita hydrolysis reactions, cross-linking uye curing kuti agadzire high-molecular siloxane polymers, izvo zvinovaka chidziviriro chakasimba che coating. Panguva iyi, zinc powder iri mu coating inoita basa rekudzivirira electrochemical. Zvigadzirwa zve corrosion zvinozadza voids ye coating film, zvichidzivirira kuparadzwa kwe media inokuvadza, zvichibvumira chinhu chakafukidzwa kuchengetedza mamiriro akanaka kwenguva yakareba kunyangwe munzvimbo dzakaoma. Inoshandiswa zvakanyanya mukuvaka ngarava, petrochemicals, zvivakwa zvekunze kwenyika nedzimwe nzvimbo. Muindasitiri yekugadzira zvinhu nemazvo, ethyl silicate inonyanya kukosha. Sechinobatanidza jecha molds, inogona kugadzira zvinhu zvine simba rekubatanidza mushure me hydrolysis. Kana ikasanganiswa nezvinhu zvinoramba kushanda pakugadzira jecha rekuumba, mushure mekuomeswa, firimu remhando yepamusoro rinodzivirirwa pakupisa kwakanyanya uye rakanaka rinobuda rinoumbwa pamusoro pejecha rekuumba, zvichiita kuti pamusoro pejecha rekuumba pave pakanaka uye kurongeka kwaro kwakakwirira zvikuru. Rakakodzera zvikuru kugadzira zvikamu zvakarurama mundege nedzimwe nzvimbo. Kwete izvozvo chete, ethyl silicate inogona kushandiswa sechinhu chinodzivirira kupisa muindasitiri yezvemagetsi, zvichipa vimbiso yekushanda kwakasimba kwemidziyo yemagetsi. Inoshandiswa kugadzira girazi remaziso, izvo zvinogona kuwedzera zvakanyanya kufambiswa kwechiedza charo uye kupa zvishandiso zvemaziso "nzvimbo yekuona" yakajeka. Upfu hwakatsetseka kwazvo hwesilica hunogadzirwa mushure mekudzima zvachose huchiri chinhu chakakosha chekugadzira phosphors. Inogona zvakare kushandiswa mukugadzirwa kweorganic kugadzira silicone solvents uye chinhu chakakosha chesilicone oil, ichitamba basa rakakosha munyika yezvinhu zvesilicone. Kusarudza ethyl silicate zvinoreva kusarudza mhinduro dzemaindasitiri dzemhando yepamusoro uye dzinoshanda zvakanaka. Kungave kuri kuwedzera mashandiro ekudzivirira uye kururama kwezvigadzirwa zvako kana kuwedzera nzvimbo dzekushandisa, ethyl silicate inogona kupinza simba guru mukugadzirwa kwako kwemaindasitiri, ichikubatsira kuti usiyane nevamwe muindasitiri uye kugadzira mikana yakawanda!
