Galasi ya ma borosilticate yapeza chidwi chifukwa cha zomveka zake pagalasi yokhazikika popanga zodzikongoletsera ndi ntchito zina zambiri. Koma kodi ndizabwinodi?
Munkhaniyi, timakhala m'magawo, mikhalidwe, zabwino zamagalasi okhazikika, ndi mitundu yosiyanasiyana ya galasi la mabotolo kuti tiwonetsetse nkhaniyi.
Kodi galasi ndi lotani?
Magalasi opangira maboti amapangidwa kuchokera ku zosakaniza ziwiri zazikulu: silica ndi Boron. Malo osungunuka a silika amakhala okwera kwambiri (1730 ° C), kuti apange zinthuzi pang'onopang'ono ndikupulumutsa mphamvu, zinthu zina zotchedwa Fluxes zimawonjezeredwa. Komanso okhazikika (alkine olima, alumina, ndi alkiline oxides) amawonjezeredwa kuti alimbikitse galasi, lomwe limapereka katundu wabwino.
Kapangidwe ka borotil
Borosiltial Galasi Yabwino Kwambiri Mankhwala: Kukhazikika kwambiri kwa mankhwala ndi kukhazikika kwa malo okhalamo. Kukana kutentha kwambiri: kukana kwabwino kwambiri pamagetsi owombera ndi ma gradel a mafuta, komanso kuwonjezeka kotsika. Mphamvu yamakina kwambiri: kuvala bwino- komanso kukwapula, ndi mphamvu yodalirika yotheratu komanso kuthekera kupirira ndalama zongofuna kulimbana ndi katundu wamakina. Kuwonekera Kwambiri: Kuonetsetsa kuti pali zomveka bwino komanso zosokoneza. Mitundu ya galasi la
borosiltimiritsa magalasi amabwera m'mitundu yosiyanasiyana kutengera zomwe amizidwa a Boron, zomwe zimakhudza mawonekedwe ake. Mitundu iyi ikuphatikiza:
galasi lotsika la borosilther: Mtunduwu uli ndi gawo lotsika la boron oxide, nthawi zambiri kuyambira 5% mpaka 10%. Imakhala ndi nkhawa yothetsera mavuto ndipo nthawi zambiri imagwiritsidwa ntchito pazinthu zapakhomo ngati cookware ndi kumwa. Magalasi apakatikati: okhala ndi a Boron oxide oxide kuyambira 10% mpaka 13%, galasi la ma borosilal amaperekanso chiwopsezo choyerekeza ndi mitundu yotsika ya borotilmil. Imapeza mapulogalamu mu zida za labotale ndi makonda omwe amakhala okwera kwambiri. Magalasi apamwamba kwambiri: galasi lalikulu la borosilther mulingo wapamwamba kwambiri wa boron oxide, nthawi zambiri amapitilira 13%. Mtunduwu umadzitamandira kwambiri ndi kukhazikika kwa mankhwala, kupangitsa kukhala koyenera kofunikira pofuna kugwiritsa ntchito galasi ngati laboratore galasi komanso othamanga kwambiri. Pomaliza pamapeto
, galasi la borosilate limapereka zabwino zambiri pagalasi yokhazikika, kuphatikizapo mantha apamwamba ndi kukana kwapakatikati ndi kugwiritsa ntchito mankhwala, komanso kukhazikika kwamphamvu. Ngakhale galasi la maboti lingabwere pamtengo wokwera, momwe zimakhalira ndi moyo wapadera komanso kukhala ndi moyo wautali nthawi zambiri.
