Popeza kuti chophimba chophimbacho chakhala chakhanda, chasinthidwa kangapo m'zaka zochepa chabe.Kuchokera pa zida zoyamba za PET, mawonekedwe a matte, pamwamba pa matte, ndi zina zambiri, zasinthidwa pang'onopang'ono kukhala chitetezo chagalasi lotentha.Zomata, komabe, zomata zamagalasi osapumira zimawonekanso kuti zikukumana ndi zovuta zomwe zimatetezedwa ndi PET: chisokonezo chazinthu, mtundu wosagwirizana, mtengo wopusa….
Zinthu zazikulu zomwe zimatsimikizira mtundu wa zoteteza magalasi
Pali mitundu iwiri ikuluikulu yamagalasi owuma: imodzi ndi chinthu chokha, ndipo inayo ndi vuto lakugwiritsa ntchito.Kuchokera pazogulitsa zokha, ngati chomata chagalasi chosalimba chimawunikidwa kuchokera kuzinthu zopangira ndi kupanga.
1. Zopangira
Woteteza galasi aliyense amapangidwa kuchokera kumitundu yosiyanasiyana ya zida zamagalasi, ndipo mphamvu yamagalasi pakati pa zida zosiyanasiyana zimasiyana.
2, njira yopanga
Pali zisankho zazikulu zitatu zodziwira mtundu wa chitetezo chagalasi:
1.CNC kudula
Dulani zinthu zamagalasi mu mawonekedwe oyenera chitsanzo cha foni
2. Kupukuta m'mphepete mwa Arc
Pulitsani m'mphepete mwa galasi lowongoka kukhala 2.5D arc
3. Kutentha kwa ng'anjo
Mu ng'anjo yotentha kwambiri ndi potaziyamu nitrate, mphamvu ya wotetezera galasi imawonjezeka, ndipo kulimba kumawonjezeka kwambiri.Ngakhale chomata chagalasicho chathyoledwa, sichidzavulaza anthu.
Njira zitatuzi ndizinthu zitatu zomwe zingapangitse zomata zoteteza magalasi.
Pamene kudula kapena kupukuta sikuli bwino, m'mphepete mwake mukhoza kukhala pakona, zomwe zimapangitsa galasi kuphulika mosavuta.Pamene kutentha kwa ng'anjo yotentha sikukwanira, ndipo zinthu zomwe zimagwiritsidwa ntchito pa potaziyamu nitrate sizili bwino, mphamvu ndi kulimba zidzatsitsidwa.
Komabe, zinthu zambiri zosalongosoka zidzachotsedwa pakupanga, koma zochepa zowonongeka sizidziwikiratu ndi maso.Pamene mphemvu yaing'ono ikugwiritsidwa ntchito ngati mankhwala abwino kuti alowe mumsika, ming'alu imachitika ngati itagwiritsidwa ntchito pang'ono.
Zida zoteteza galasi
Malinga ndi gulu la zipangizo galasi, akhoza kugawidwa mu galasi soda-laimu ndi galasi aluminiyamu silika.Soda-laimu galasi ndi galasi lofala kwambiri m'moyo wathu.Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.Ndi galasi ndi mbiri yaitali ndi njira luso ndithu zovuta kwambiri.Njira yaukadaulo ndiyotsika, ndipo mafakitale ang'onoang'ono agalasi amathanso kupanga magalasi a soda.Komabe, luso la galasi la ndondomeko ya fakitale iliyonse ndi yosiyana, ndipo pali kukhazikika kosiyana.Pakadali pano, Japan AGC ndi Schott yaku Germany ndizomwe zili ndi nano-calcium.Ogulitsa magalasi, ngakhale kuti zomera ziwirizi sizitsika mtengo, koma chifukwa chake sichinthu choposa kutsimikizira kukhazikika kwa khalidwe la galasi.
Pakalipano, galasi la gorila la Corning limapangidwa ndi galasi la aluminosilicate, makamaka potengera kuwonjezeredwa kwa aluminiyamu ndi zinthu zosawerengeka zapadziko lapansi ku galasi la soda-laimu, ndiyeno amasinthanitsa ayoni a sodium ndi potaziyamu kudzera muukadaulo wapadera wopititsa patsogolo kufalikira kwake.Kugonana ndi kuuma, chifukwa chapamwamba kwambiri cha teknoloji yamakono, mtengo wa galasi ndi wapamwamba kwambiri kuposa galasi la soda laimu.
Tsopano Dragontrail waku Japan AGC ndi galasi la Xensation Cover la Schott waku Germany akhala akufufuzidwa m'zaka zaposachedwa, ndipo adayambitsanso galasi la aluminium-silicon, lomwe limatsindika kufalikira kwapamwamba komanso kulimba, poyerekeza ndi galasi la Corning Gorilla, ndi mtsogolo. aluminium silicon.Ngati luso la galasi likutchuka ndi anthu ambiri, mtengo ukhoza kutsika pang'onopang'ono.
Mlingo wa chitetezo cha magalasi
Nthawi yotalikirapo, imakhala yolimba komanso yolimba, nthawi yotentha nthawi zambiri imakhala maola 3-6, zotsatira zake zimakhala zoposa maola 6, ndipo nthawi yovuta ndi maola anayi.Pasanathe maola 4 sangatchulidwe galasi lotentha.Zoteteza zamagalasi zotsika mtengo zomwe zimapezeka pamalonda zimakhala ndi nthawi yotentha yochepera 2 mpaka 3 maola, ndipo ena amakhala ndi ola limodzi lokha, osasokoneza.
Pali njira ziwiri zopangira magalasi otentha:
Kutentha thupi
Galasiyo ikatenthedwa mpaka kutentha kwambiri, galasiyo imakhazikika mofulumira, ndipo galasi pamwamba pake imapangidwa "yolimba" chifukwa cha kusiyana kwakukulu kwa kutentha kwa thupi la galasi, kotero kuti galasi likhale lolimba kwambiri kuposa galasi. galasi wamba.
Kutentha kwa Chemical
Magalasi ambiri oteteza magalasi amagwiritsidwa ntchito motere.Kumiza galasi mu kutentha kwambiri mankhwala yogwira zitsulo zitsulo njira, ndi kusinthanitsa utali wozungulira ayoni lalikulu ndi ma ion utali wozungulira ang'onoang'ono (monga lithiamu ayoni) mu galasi, kenako kuzirala, ndi ma ion lalikulu utali wosinthanitsa pamwamba adzakhala mbamuikha motsutsana ndi galasi.Pamwamba kuti mukwaniritse kutentha.
