Kodi galasi lofewa limapangidwa bwanji?

Galasi lofewa ndi lamphamvu kwambiri kuwirikiza kanayi kuposa galasi "lachizolowezi," kapena lofewa. Ndipo mosiyana ndi galasi lofewa, lomwe lingasweke kukhala zidutswa zokhotakhota pamene galasi losweka, lofewa liphwanyika kukhala zidutswa zazing'ono, zosavulaza. Chifukwa chake, galasi lofewa limagwiritsidwa ntchito m'malo omwe chitetezo cha anthu chili vuto. Ntchito zake zimaphatikizapo mawindo am'mbali ndi akumbuyo m'magalimoto, zitseko zolowera, malo osambira ndi mabafa, mabwalo a racquetball, mipando ya patio, ma uvuni a microwave ndi ma skylights.

Kuti galasi likonzedwe kuti ligwiritsidwe ntchito potenthetsera, liyenera kudulidwa kaye kukula komwe mukufuna. (Kuchepetsa mphamvu kapena kulephera kwa chinthu kungachitike ngati ntchito iliyonse yopangira, monga kudula kapena kuphimba, itachitika pambuyo potenthetsera.) Kenako galasilo limafufuzidwa kuti lione zolakwika zomwe zingayambitse kusweka pa sitepe iliyonse panthawi yotenthetsera. Chotsukira monga sandpaper chimatenga m'mbali zakuthwa kuchokera pagalasi, zomwe pambuyo pake zimatsukidwa.
KULEMBETSA

Kenako, galasi limayamba njira yotenthetsera kutentha komwe limadutsa mu uvuni wotenthetsera, kaya mu batch kapena continuous feed. Uvuni umatenthetsa galasi mpaka kutentha kopitilira madigiri 600 Celsius. (Muyezo wa makampani ndi madigiri 620 Celsius.) Kenako galasi limadutsa njira yozizira kwambiri yotchedwa "kuzimitsa." Panthawiyi, yomwe imatenga masekondi ochepa, mpweya wopanikizika kwambiri umaphulitsa pamwamba pa galasi kuchokera ku nozzles zosiyanasiyana m'malo osiyanasiyana. Kuzimitsa kumaziziritsa pamwamba pa galasi mwachangu kwambiri kuposa pakati. Pakati pa galasi likazizira, limayesa kubwerera kuchokera pamwamba pakunja. Zotsatira zake, pakati pa galasi limakhalabe ndi mphamvu, ndipo pamwamba pakunja pamakhala kupsinjika, zomwe zimapatsa galasi loziziritsa mphamvu.

Galasi lomwe lili ndi mphamvu limasweka mosavuta kasanu kuposa momwe limasweka mu mphamvu. Galasi losweka limasweka pa mapaundi 6,000 pa sikweya mainchesi (psi). Galasi lofewa, malinga ndi zomwe boma likunena, liyenera kukhala ndi mphamvu yophwanyidwa pamwamba pa psi 10,000 kapena kuposerapo; nthawi zambiri limasweka pa psi pafupifupi 24,000.

Njira ina yopangira magalasi otenthetsera ndi chemical tempering, momwe mankhwala osiyanasiyana amasinthira ma ayoni pamwamba pa galasi kuti apange compression. Koma chifukwa njira iyi imadula kwambiri kuposa kugwiritsa ntchito tempering uvuni ndi quenching, siigwiritsidwa ntchito kwambiri.
