galasi lotentha

Galasi yotentha/Galasi yowonjezera ndi galasi lotetezera.Magalasi otenthedwa kwenikweni ndi mtundu wagalasi lokhazikika.Pofuna kupititsa patsogolo mphamvu ya galasi, njira za mankhwala kapena zakuthupi zimagwiritsidwa ntchito popanga kupsinjika maganizo pamwamba pa galasi.Galasiyo ikagwiritsidwa ntchito ndi mphamvu yakunja, imayamba kuchepetsa kupanikizika kwapamwamba, potero imakweza mphamvu yonyamula ndikuwonjezera kukana kwa galasi lokha.Mphepo kuthamanga, kuzizira ndi kutentha, zimakhudza, etc. Samalani kusiyanitsa ndi galasi CHIKWANGWANI analimbitsa pulasitiki.
udzu
Galasi ndi amorphous inorganic non-metallic material, kawirikawiri amapangidwa ndi mitundu yosiyanasiyana ya mchere (monga mchenga wa quartz, borax, boric acid, barite, barium carbonate, laimu, feldspar, soda phulusa, etc.) wa.Zigawo zake zazikulu ndi silika ndi oxides zina.Mankhwala opangidwa ndi galasi wamba ndi Na2SiO3, CaSiO3, SiO2 kapena Na2O · CaO · 6SiO2, etc. Chigawo chachikulu ndi silicate mchere wawiri, womwe ndi amorphous olimba ndi mawonekedwe osasintha.Amagwiritsidwa ntchito kwambiri m'nyumba kuti atseke mphepo ndi kuwala, ndipo ndi osakaniza.Palinso magalasi achikuda osakanizidwa ndi oxides kapena mchere wazitsulo zina kusonyeza mtundu, ndi magalasi otenthedwa omwe amapezedwa ndi njira zakuthupi kapena zamankhwala.Mapulasitiki oonekera monga polymethyl methacrylate nthawi zina amatchedwa galasi la machitidwe opanga ulimi.
kupsyinjika
Prestressing force ndi kupanikizika kopanikizika komwe kumagwiritsidwa ntchito pamapangidwewo pomanga kuti apititse patsogolo magwiridwe antchito a kapangidwe kake.Munthawi yautumiki wa kapangidwe kake, kupanikizika kwapang'onopang'ono kumatha kuthetsa kwathunthu kapena pang'ono kupsinjika komwe kumachitika chifukwa cha katundu ndikupewa kuwonongeka kwamapangidwe.Nthawi zambiri amagwiritsidwa ntchito m'mapangidwe a konkire, ndikuyika kukakamiza konkriti pasadakhale isananyamule katunduyo, kotero kuti mphamvu yamkati ya konkire m'dera lamakokedwe pomwe katundu wakunja amatulutsa kupsinjika, kutsitsa kapena kuchepetsa kupsinjika kwamakokedwe kopangidwa ndi katundu wakunja, kuti kapangidwe kake kasang'ambe kapena kusweka mochedwa ndikugwiritsa ntchito bwino.
