Galasi ndi mtundu wa amorphous inorganic non-metal zinthu zopangidwa ndi mchere wambiri (monga mchenga wa quartz) ndi zochepa zopangira zowonjezera, chigawo chachikulu ndi silicon dioxide.Kuthekera kwa magalasi ndikwabwino kwambiri, kulibe kuipitsidwa, mafashoni amphamvu, mafanizidwe olemera omwe amagwiritsidwa ntchito kwambiri, otsika mtengo.
Kukula kwa nkhungu ndikolondola, kumatha kupanga zinthu zopepuka komanso zoonda, ndipo mtundu wake ndi wolemera komanso wosinthika ndi wosangalatsa. Chifukwa ndi osakaniza, amorphous, palibe malo osungunuka ndi otentha.Galasi kuchokera ku cholimba kupita ku madzi ndi dera linalake la kutentha (ie, kufewetsa kutentha osiyanasiyana), kuchokera kumalo osungunuka kupita kumalo olimba a ndondomekoyi imakhalanso pang'onopang'ono, mosalekeza.Pamene kutentha kumachepa pang'onopang'ono, kukhuthala kwa galasi kusungunuka kumawonjezeka pang'onopang'ono, ndipo pamapeto pake galasi lolimba limapangidwa.Choncho, chinthu chapadera ichi cha galasi chimapanga chikhalidwe chabwino cha mapangidwe amisiri yamagalasi.Nanga ndichifukwa chiyani magalasi opangira shuga amakondedwa kwambiri ndi ana?
Pazida zonse, mitsuko yagalasi ndiyo yathanzi.Mtsuko wagalasi ulibe mankhwala achilengedwe powombera.Anthu akamagwiritsa ntchito mtsuko wagalasi kuyika maswiti, sayenera kuda nkhawa kuti mankhwalawo adzadyedwa m'mimba.Komanso, galasi pamwamba ndi yosalala ndi yosavuta kuyeretsa, ndipo mabakiteriya ndi dothi n'zosavuta kukula mu kapu khoma.
【 Tanthauzo】
Chidebe chagalasi ndi mtundu wa chidebe chowonekera chopangidwa ndi zinthu zamagalasi osungunula poziwombera ndi kuumba.Zotengera zamagalasi zimagwiritsidwa ntchito kwambiri kulongedza zamadzimadzi, mankhwala olimba komanso zakumwa zamadzimadzi.
【 Kubiriwira】
Poyerekeza ndi pulasitiki ndi zitsulo ma CD, galasi ali otsika mpweya woipa mu mkombero moyo wonse kuchokera ku migodi, mayendedwe, kupanga ndi kupanga zopangira, kunyamula zinthu zomalizidwa, kumwa ndi kubwezeretsanso, ndi otsika mpweya woipa.
【 Chitetezo】
Galasi imadziwika kuti ndi yosungika bwino kwambiri padziko lonse lapansi.Mulibe bisphenol A kapena plasticizer.Ndi kukhazikika kwa mankhwala odalirika ndi chotchinga, palibe kuipitsidwa kwa zovala, kotero kusankha zinthu zamagalasi ndikusankha thanzi, kusankha chitetezo.
[Kuzungulira]
Galasi ili ndi mphamvu zopanda malire, galasi lokha likhoza kubwezeretsedwanso ndikugwiritsidwanso ntchito popanda kutsika mtengo, ndipo kuzungulira sikutha.Lamulo la zinthu ndi lodziwika kwambiri mu galasi.
【 Chikhalidwe chaumunthu】
Ntchito yapadera yamakono komanso kukongola kwagalasi yogwiritsira ntchito tsiku ndi tsiku kumatha kuwonetsa bwino kwambiri ntchito yabwino kwa anthu.
