Kagwiritsidwe Ntchito
Ethyl silicate (TEOS) ndi madzi opanda mtundu, omwe amagwiritsidwa ntchito makamaka ngati zokutira zoteteza kutentha, zokutira zoteteza mankhwala, zolumikizira za silane, zolumikizira zachilengedwe, komanso ngati choyambira cha mafilimu a chemical vapor deposition (CVD)SiO2 m'munda wa semiconductor, ndi zina zotero. Malo osungunuka a ethyl silicate ndi -77℃, ndipo malo ake owira ndi 165.5℃. Amasungunuka pang'ono m'madzi ndipo amasungunuka mu ethanol ndi ether.
Amagwiritsidwa ntchito ngati chinthu chotetezera kutentha m'makampani amagetsi komanso ngati chothandizira kukonza magalasi owonera ndi coagulant.
Amagwiritsidwa ntchito popangira zinthu molunjika ngati chomangira cha nkhungu zamchenga; Pamwamba pa chitsulo chothiridwa ndi nthunzi ya ethyl silicate chingalepheretse dzimbiri ndi madzi. Ethyl silicate ingagwiritsidwe ntchito kuviika pamwamba pa zitsulo ndi silicon, ndipo kukonza galasi lowala kumatha kuwonjezera kuwala kwake. Ufa wabwino kwambiri wa silika womwe umapangidwa pambuyo pa hydrolysis yonse ungagwiritsidwe ntchito kupanga phosphors. Ethyl silicate ndi zinthu zopangira mafuta a silicone. Ethyl silicate ingagwiritsidwenso ntchito popanga zophimba zoteteza kutentha komanso zoteteza mankhwala. Ku Japan, 90% ya ethyl silicate imagwiritsidwa ntchito ngati maziko a zophimba zoteteza dzimbiri (utoto wolemera zinc).
Amagwiritsidwa ntchito makamaka mu zophimba zosagwira mankhwala ndi zophimba zosagwira kutentha, silicone solvents ndi zomatira zolondola. Pambuyo pa hydrolysis yonse, ufa wosalala kwambiri wa silicon dioxide umapangidwa, womwe umagwiritsidwa ntchito kupanga phosphors ndipo ungagwiritsidwenso ntchito ngati chothandizira cha mankhwala.
Tetraethoxysilane imagwiritsidwa ntchito kwambiri mu magalasi owoneka bwino, zokutira zosagwirizana ndi mankhwala, zokutira zosagwirizana ndi kutentha ndi zomatira. Kusintha kwa zokutira zotsutsana ndi dzimbiri Chothandizira kulumikiza, chomangira, chothandizira kuuma; Kupanga mafupa ofunikira ndi silica yapamwamba kwambiri
Ethyl orthosilicate imagwiritsidwa ntchito kwambiri mu magalasi owoneka bwino, zokutira zosagwirizana ndi mankhwala, zokutira zosagwirizana ndi kutentha ndi zomatira. Kusintha kwa zokutira zotsutsana ndi dzimbiri Chothandizira kulumikiza, chomangira, chothandizira kuuma; Kupanga mafupa oyambitsa ndi silika woyeretsedwa kwambiri.
Zipangizo zotetezera magetsi zamagetsi, zokutira, zotsukira magalasi, ma coagulants, kapangidwe ka organic, zosungunulira zopangira organosilicon
Mu mankhwala opangidwa ndi H+-magadiite, amakumana ndi dodecylamine pophunzira galasi losakanikirana lachitsulo. Amagwiritsidwa ntchito kwambiri ngati choyambira pokonzekera ma gels ouma.
Kulongedza ndi Kutumiza
Kulongedza: 200kg malinga ndi zosowa za makasitomala.
Kutumiza: ndi mankhwala wamba ndipo amatha kutumizidwa ndi sitima, nyanja ndi mpweya.
Stock: ali ndi stock yotetezeka ya 500MTs
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
