1. Galasi lofewa
Galasi lotenthedwa ndi mtundu wa galasi lokhazikika. Pofuna kulimbitsa mphamvu ya galasi, njira zamakemikolo kapena zakuthupi nthawi zambiri zimagwiritsidwa ntchito popanga kupsinjika pamwamba pa galasi. Galasi likamanyamula mphamvu zakunja, choyamba limathetsa kupsinjika kwa pamwamba, motero limakulitsa mphamvu yonyamula ndikuwonjezera kukana kwa mphepo, kukana nyengo komanso kukana kukhudzidwa kwa galasi lokha.
2. Galasi loteteza kutentha
Galasi loteteza kutentha linapangidwa ndi anthu aku America mu 1865. Ndilo loti lizitseke m'mbali ziwiri kapena zingapo za magalasi pamodzi, kupanga mpweya wouma pakati pa magalasi, komanso kukhala ndi mphamvu yogwira ntchito bwino. Limagwiritsa ntchito guluu wolimba komanso wokhuthala kwambiri kuti limangirire pepala lagalasi ndi chimango cha aluminiyamu chokhala ndi desiccant. Ambiri mwa iwo amapangidwa ndi mafakitale akuluakulu. Sipadzakhala banga, madzi, ndi kuzizira pakati, Lili ndi mphamvu yabwino yoteteza kutentha komanso phokoso.
3. Galasi lopaka utoto
Galasi lopaka utoto limapangidwa ndi zidutswa ziwiri kapena zingapo za galasi loyandama lokhala ndi filimu yomatira ya PVB (polyvinylbutyraldehyde), yokanikizidwa ndi chotenthetsera chotentha ndikutulutsidwa momwe zingathere, kenako nkuyikidwa mu autoclave kuti isungunule mpweya wotsala pang'ono mu filimu yomatira pansi pa kutentha kwakukulu ndi kupanikizika. Tsopano, pali mtundu watsopano wa ng'anjo, womwe ukhoza kukonza filimu yapadera ya EVA yakunja ndikumaliza njira yomatira kudzera mu kupopera vacuum yotentha kwambiri mu ng'anjo. Anthu amatha kusankha njira yoyenera malinga ndi bajeti yawo, malo ndi zomwe akufuna. Poyerekeza ndi magalasi ena, galasi lopaka utoto lili ndi mphamvu zotsutsana ndi kugwedezeka, zotsutsana ndi kuba, zoteteza zipolopolo komanso zoteteza kuphulika. Galasi lopaka utoto likasweka, silimafalikira kawirikawiri chifukwa cha kumatira kwa guluu, ndipo chitetezo chimakhala chapamwamba kwambiri.
Mphamvu ya galasi wamba wopangidwa ndi laminated si yayikulu, zomwe zimakhala zofanana ndi za galasi wamba wopangidwa ndi chidutswa chimodzi. Galasi lopangidwa ndi laminated lopangidwa ndi galasi lofewa lili ndi mphamvu komanso chitetezo. Limagwiritsidwa ntchito kwambiri m'magawo amkati, matabwa a mipanda, pansi pa siteji ndi makoma akuluakulu a makatani.
Pakadali pano, ng'anjo ya Fangding yopaka lamination ikulandiridwa kwambiri chifukwa cha malo ake ochepa, ndalama zochepa, khalidwe lake labwino komanso zokolola zambiri.
