Magalasi otenthedwa ndi galasi lokhala ndi kupsinjika kwakukulu pamwamba pake. Amatchedwanso reinforced glass. Kugwiritsa ntchito njira ya tempering kulimbitsa galasi.
Galasi yotentha ndi ya galasi lachitetezo. Magalasi otenthedwa kwenikweni ndi mtundu wa galasi lokhazikika. Pofuna kupititsa patsogolo mphamvu ya galasi, njira za mankhwala kapena zakuthupi zimagwiritsidwa ntchito popanga kupsinjika maganizo pamwamba pa galasi. Galasiyo ikagwidwa ndi mphamvu zakunja, imayamba kusokoneza kupanikizika kwapamwamba, potero kumapangitsa kuti mphamvu yake ikhale yonyamula katundu, imapangitsa kuti mphepo ikhale yolimba, kuzizira ndi kutentha, kukana kukhudzidwa, etc. Samalani kusiyanitsa ndi fiberglass.
Makhalidwe a magalasi otentha:
Chitetezo
Galasi ikawonongeka ndi mphamvu zakunja, tizidutswa timapanga tinthu ting'onoting'ono tomwe timafanana ndi zisa za uchi, zomwe sizingawononge kwambiri thupi la munthu.
mphamvu yapamwamba
Mphamvu yamagalasi otenthedwa ndi makulidwe ofanana ndi 3-5 nthawi yagalasi wamba, ndipo mphamvu yopindika ndi 3-5 kuposa yagalasi wamba.
kukhazikika kwamafuta
Galasi yotentha imakhala ndi bata labwino, imatha kupirira katatu kusiyana kwa kutentha kwa galasi wamba, ndipo imatha kupirira kusintha kwa kutentha kwa 300 ℃.
Ubwino
Choyamba ndi chakuti mphamvuyo imakhala yokwera kangapo kuposa galasi wamba, ndipo imagonjetsedwa ndi kupinda.
Chachiwiri ndi chitetezo chomwe chikugwiritsidwa ntchito, pamene mphamvu yake yonyamula katundu ikuwonjezeka ndikuwongolera kufooka kwake. Ngakhale galasi lowonongeka litawonongeka, limawoneka ngati miyala yaying'ono yopanda makonguwa, kuchepetsa kwambiri kuvulaza thupi la munthu. Kukaniza kwa magalasi otenthedwa kuti kuziziritsa mwachangu ndi kutentha kumakhala kokwera 3-5 kuposa galasi wamba, ndipo kumatha kupirira kusiyana kwa kutentha kwa madigiri oposa 250, komwe kumakhudza kwambiri kupewa kusweka kwa matenthedwe. Ndi mtundu wa galasi lachitetezo. Kuonetsetsa chitetezo cha zipangizo oyenerera nyumba mkulu-nyamuka.
Kuperewera
Kuipa kwa tempered glass:
Galasi la 1.Tempered galasi silingathe kudulidwa kapena kukonzedwanso, ndipo likhoza kusinthidwa ku mawonekedwe omwe mukufuna musanayambe kutentha.
2.Ngakhale galasi lotentha lili ndi mphamvu zamphamvu kuposa galasi wamba, limakhala ndi mwayi wodziphulika (self rupture), pamene galasi wamba ilibe mwayi wodziphulika.
3.Pamwamba pa galasi lopsa mtima likhoza kukhala losagwirizana (mawanga amphepo) ndi kupatulira pang'ono kwa makulidwe. Chifukwa cha kupatulira ndi chakuti galasi litatha kuchepetsedwa ndi kusungunuka kotentha, limakhazikika mofulumira ndi mphepo yamphamvu, zomwe zimapangitsa kuti mipata ya kristalo mkati mwa galasi ikhale yochepa komanso kupanikizika kumawonjezeka. Choncho, galasi ndi woonda pambuyo kutentha kuposa kale. Nthawi zambiri, galasi la 4-6mm limacheperachepera 0.2-0.8mm pambuyo potenthetsa, pomwe galasi la 8-20mm limachepera 0.9-1.8mm pambuyo potentha. Digiri yeniyeni imadalira zida, zomwe ndichifukwa chake magalasi otenthedwa sangathe kukhala ndi galasi lomaliza.
4.Galasi lathyathyathya lomwe limagwiritsidwa ntchito pomanga pambuyo pa kutentha kwa thupi mu ng'anjo yotentha nthawi zambiri limakhala lopindika, ndipo kuchuluka kwa mapindikidwe kumatsimikiziridwa ndi zida ndi machitidwe a akatswiri. Pamlingo wina, zimakhudza zokongoletsa (kupatula zosowa zapadera).
Kuyesa zinthu za tempered glass
1. Kuyang'anira maonekedwe
Kuyang'anira maonekedwe ndi njira yoyamba yoyang'anira magalasi otenthedwa, yomwe makamaka imaphatikizapo kuyang'ana pamwamba pa galasi, kuphatikizapo kuyang'ana zolakwika monga ming'alu, thovu, ndi zokopa.
2. Kupindakuyesa mphamvu
Mphamvu yopindika ndi chimodzi mwazizindikiro zazikulu zamagalasi opumira komanso gawo lofunikira pakuwunika mphamvu yagalasi. Kuyesa mphamvu yopindika nthawi zambiri kumagwiritsa ntchito njira zinayi zopindirira, zomwe zimagwiritsa ntchito mphamvu pa mbale yagalasi ndikuwona momwe zimaduka kuti zipeze mphamvu yopindika.
3. Kuzindikira kwa magawo a magawo
Magalasi otenthedwa amawonetsa kugawanika kowonekera pambuyo pa kusweka, makamaka kugawanika kukhala ma radial fragmentation ndi mitundu yosweka. Njira yodziwira nthawi zambiri imagwiritsa ntchito kuyang'ana kwa microscopic kuti iwunikire momwe imagawanika.
4. Kuyesa kwa kuwala kwa galasi lopsa mtima
Zowoneka bwino za galasi lotentha ndizofunika kwambiri pakugwiritsa ntchito kwake. Zizindikiro za kuwala kwa galasi lotentha zimaphatikizapo kutumizirana, kuwonetsetsa kosiyana, kusiyana kwa mitundu, ndi zina zotero. Njira yodziwira nthawi zambiri imagwiritsa ntchito spectrophotometer kapena colorimetric mita poyesa.
5. Kuyang'ana kwapamwamba kwa chithandizo cha kutentha
Kwa galasi lotenthetsera kutentha, kutentha ndi nthawi ndizo zinthu zazikulu zomwe zimakhudza ntchito yake. Choncho, chifukwa cha chithandizo cha kutentha, ndikofunikira kuzindikira magawo monga kupsinjika kwa pamwamba, kupindika, ndi ming'alu pa galasi.
