Ethyl silicate: Zinthu zamatsenga m'munda wamafakitale

Mu dziko lalikulu la zipangizo zamafakitale, ethyl silicate imadziwika ngati nyenyezi yowala, yomwe imabweretsa zatsopano ndi kupita patsogolo m'mafakitale ambiri chifukwa cha makhalidwe ake apadera komanso ntchito zake zosiyanasiyana. Ethyl silicate ndi madzi opanda mtundu komanso owonekera kutentha kwa chipinda ndipo ali ndi fungo lapadera. Mu malo opanda madzi, imakhala yokhazikika komanso yodalirika. Komabe, ikakumana ndi madzi, imawola mwaluso kukhala ethanol ndi silicic acid, ndipo pang'onopang'ono imakhala yonyowa mumlengalenga wonyowa. Kapangidwe kabwino kameneka kamathandiza kuti ikhale ndi gawo lofunikira kwambiri pakupanga zinthu zambiri zamakemikolo ndi zinthu zina. Imasungunuka mosavuta mu zinthu zachilengedwe monga mowa ndi ether, yokhala ndi molekyulu ya, malo osungunuka otsika ngati, ndi malo owira a. Kuchokera pamalingaliro a njira yokonzekera, imapezeka mosamala pothira distillation pambuyo pa kuyanjana pakati pa silicon tetrachloride ndi anhydrous ethanol. Njira yokonzekerayi yokhwima imatsimikizira kuti ethyl silicate ndi yabwino komanso yokhazikika. Mu ntchito zothandiza, ethyl silicate imatha kuonedwa ngati "jack of all trades". Mu gawo la zophimba, ndiye chinthu chofunikira kwambiri popanga zophimba zosatentha komanso zosagwira mankhwala. Ku Japan, mpaka 90% ya ethyl silicate imagwiritsidwa ntchito ngati maziko a zokutira zotsutsana ndi dzimbiri (utoto wolemera mu zinc). Pambuyo popopera, magulu a alkoxy omwe ali mu kapangidwe kake ka molekyu amatha kuyamwa chinyezi kuchokera mumlengalenga ndikuchita ma hydrolysis reactions, cross-linking ndi critering kuti apange ma polima a siloxane okhala ndi mamolekyulu ambiri, omwe amapanga chotchinga champhamvu cha zokutirazo. Pakadali pano, ufa wa zinc womwe uli mu zokutirazo umagwira ntchito yoteteza zamagetsi. Zinthu zowononga zimadzaza malo opanda kanthu a filimu yokutirazo, kuletsa kuwonongeka kwa zinthu zovulaza, kulola chinthu chophimbidwa kuti chikhale bwino kwa nthawi yayitali ngakhale m'malo ovuta. Chimagwiritsidwa ntchito kwambiri popanga zombo, petrochemicals, malo akunja ndi madera ena. Mumakampani opanga zinthu zolondola, ethyl silicate ndi yofunika kwambiri. Monga chomangira cha nkhungu zamchenga, imatha kupanga zinthu zokhala ndi mphamvu yolimba yolumikizirana pambuyo pa hydrolysis. Akasakaniza ndi zinthu zotsutsa kuti agwiritse ntchito mchenga wopangira zinthu, akauma, filimu yolimba komanso yabwino yochotsa zinthu imapangidwa pamwamba pa mchenga wopangira zinthu, zomwe zimapangitsa kuti pamwamba pa chopangira zinthucho pakhale posalala komanso kulondola kwake kukhale kwakukulu kwambiri. Ndi yoyenera kwambiri popanga zinthu zolondola mumlengalenga ndi m'madera ena. Sikuti kokha, ethyl silicate ingagwiritsidwe ntchito ngati chinthu chotetezera kutentha mumakampani amagetsi, zomwe zimapangitsa kuti zida zamagetsi zizigwira ntchito bwino. Imagwiritsidwa ntchito pokonza magalasi owunikira, omwe amatha kuwonjezera kuwala kwake ndikupatsa zida zamagetsi "malo owonekera bwino". Ufa wa silica wabwino kwambiri womwe umapangidwa pambuyo pa hydrolysis yonse ukadali chinthu chofunikira kwambiri popanga phosphors. Ingagwiritsidwenso ntchito popanga zinthu zachilengedwe kuti ikonze zosungunulira za silicone ndipo ndi chinthu chofunikira kwambiri pamafuta a silicone, chomwe chimagwira ntchito yofunika kwambiri padziko lonse lapansi la zinthu za silicone. Kusankha ethyl silicate kumatanthauza kusankha njira zamafakitale zapamwamba komanso zogwira ntchito bwino. Kaya ndi kukulitsa magwiridwe antchito oteteza komanso kulondola kwa zinthu zanu kapena kukulitsa minda yogwiritsira ntchito zinthu, ethyl silicate ikhoza kuyika chilimbikitso champhamvu pakupanga kwanu mafakitale, kukuthandizani kuonekera bwino mumakampani ndikupanga mwayi wambiri!
