Tsopano, mitundu ndi kukula kwa zinthu zamagalasi zikuchulukirachulukira, ndipo zinthu zina zamagalasi zitha kugwiritsidwa ntchito ngati ziwiya zophikira.Komabe, chifukwa ogula ena samamvetsetsa zida zenizeni komanso kuchuluka kwa zinthu zamagalasi, adagulidwa ndikugwiritsidwa ntchito molakwika, ndipo zinthu zina zamagalasi zaphulika ndikuvulaza anthu.
Pakali pano, magalasi omwe ogula nthawi zambiri amakumana nawo m'moyo wapakhomo amaphatikizapo magulu atatu: galasi wamba, galasi lotentha ndi galasi losatentha.Magalasi wamba sangathe kugwiritsidwa ntchito m'malo ogwiritsira ntchito kutentha kwakukulu (ng'anjo, uvuni wa microwave);Magalasi otenthedwa ndi chinthu chopangidwa bwino chomwe chimatenthedwa ndi galasi wamba la soda kuti chiwongolere kukana kwamakina, kuwongolera kukana kwake kwamafuta kumakhala kochepa;Magalasi ambiri osagwira kutentha ndi a gulu la galasi la borosilicate, komanso amaphatikizapo galasi la microcrystalline ndi mitundu ina.Chifukwa cha mitundu yosiyanasiyana yamankhwala, kapangidwe kake kamakhalanso kosiyana ndi magalasi wamba kapena magalasi opumira, galasi la borosilicate lili ndi kachulukidwe kakang'ono kakuwonjezera kutentha, ndipo imakhala ndi kukana kwabwino kwa kutentha komanso kukana kutentha.Ndizoyenera kugwiritsidwa ntchito ngati chidebe chopangira chakudya kukhitchini ndipo zitha kuyikidwa mwachindunji mu uvuni wa microwave ndi uvuni.
Zipangizo zamagalasi zosagwira kutentha m'khitchini makamaka zimakhala ndi tebulo losatentha kutentha, ziwiya za bokosi zosungirako zatsopano zosagwira kutentha komanso zophikira, zomwe zimatha kugawidwa kukhala moto wotseguka ndi moto wakuda.Galasi yosamva kutentha yokhala ndi mphamvu yokulirapo yotsika kwambiri, monga galasi la microcrystalline, imakhala ndi mphamvu yotentha yofikira 400°C.Zomwe zili pamwambazi zimagwiritsidwa ntchito kwambiri potenthetsera moto wotseguka, kuphika komanso kupirira kutentha ndi kuziziritsa.Zogulitsa zamagalasi pamoto wakuda zimakhala ndi mphamvu yotenthetsera ya 120 pamwamba pa ℃, imagwiritsidwa ntchito kwambiri pakuwotcha ndi kuphika popanda moto wotseguka, monga mauvuni ndi mavuni a microwave.Ndiwogulitsa magalasi wamba osagwira kutentha pamsika, monga galasi la borosilicate.Komabe, pakali pano, kulembedwa kwa zinthu zamagalasi pamsika sikumveka bwino, ndipo ena ogwira ntchito amatanthauzanso kusokoneza lingaliro ndikukulitsa ntchito ya magalasi owawa wamba komanso magalasi wamba.Chifukwa chake, China Consumers Association imakumbutsa ogula kuti azilabadira:
1. Galasi wamba sangathe kugwiritsidwa ntchito potenthetsa ndi kuphika malo, monga osagwiritsidwa ntchito mu uvuni ndi mavuni a microwave, magalasi otsekemera omwe sali opangidwa ndi homogenized, monga mu uvuni, kugwiritsa ntchito mavuni a microwave kungayambitse ngozi yodziphulika ndi kuvulala. (pakali pano galasi lotentha la "homogenized" limagwiritsidwa ntchito makamaka pazinthu zamakampani, monga galasi lamagalimoto, zitseko zomanga ndi mawindo, mipando, ndi zina zotero).
2. Pakalipano, palibe zomwe zimatchedwa kuti magalasi osatentha osatentha kapena magalasi osagwira kutentha pamsika wamsika.Ogula sayenera kusocheretsedwa pogula.
3. Zopangira magalasi zosagwira kutentha ziyenera kuikidwa ndi zilembo zofanana, kusonyeza kutentha kwa ntchito, kugwiritsa ntchito zosiyanasiyana, ndi zina zotero. Pakalipano, galasi la borosilicate ndilo magalasi ambiri osagwira kutentha, pamene galasi la microcrystalline limakhala ndi kutentha.
4. Magalasi osamva kutentha amapezedwa ndi annealing ndi kuziziritsa, ndi kukhazikika kwabwino kwa kutentha, kutentha kwakukulu kosasunthika kutentha kwadzidzidzi, kupanga kovuta komanso mtengo wapamwamba wopanga.Ngati ogula apeza zinthu zokhala ndi magalasi osamva kutentha mwadzina koma zotsika mtengo pogula, ayenera kuganizira zowona.
