Doa Na Windo Sealant: Wanpela Bikpela Samting Bilong Bildim Eneji Efisiensi na Komfot

Ol 'sealant' bilong dua na windo, olsem ol bikpela samting long wokim ol liklik samting long bilding, i save mekim bikpela wok long mekim bilding i no ken go insait long win, wara, na yusim gut pawa. Bikpela wok bilong ol em long pulapim ol spes namel long ol freim bilong dua na windo, ol wol, na glas, na stopim win long go insait, wara bilong ren i go insait, na lus bilong pawa, na long dispela rot ol i mekim gutpela sindaun insait long haus na straksa bilong bilding i stap longpela taim.

 

Long lukluk long kain samting, ol 'sealant' bilong dua na windo i save stap long tripela lain: 'silicone sealants', 'polyurethane sealants', na 'modified silane sealants'. Ol 'silicone sealants', wantaim gutpela weta na UV resistans bilong ol, ol i save yusim planti taim long pasim ol dua na windo join longpela taim. Ol 'polyurethane sealants', wantaim strongpela 'bonding' na 'elastic recovery' bilong en, em i gutpela long ol hap we i gat bikpela 'dynamic loads'. Ol 'silane sealants' we ol i senisim, wantaim liklik VOC emisen na ol i no bagarapim envairomen, i wok long kamap olsem ol gutpela samting bilong ol grinpela bilding.

Taim ol i putim, gutpela bilong putim 'sealant' i save mekim wok bilong en i kamap gutpela. Pastaim long putim, klinim gut pes bilong 'substrate' bilong meksua olsem i no gat oil, das, na ol narapela pipia. Yu mas makim wanpela gutpela 'primer' bihainim ol pasin bilong dispela samting bilong strongim 'adhesion'. Taim yu putim 'sealant', yu mas meksua olsem 'sealant joint' i gat wankain na wankain 'thickness' (ol i save tok em i mas 6-12mm), na yusim ol gutpela rot bilong pinisim bilong abrusim ol 'bubble' o 'crack'. Na tu, strong bilong 'sealant' i mas wankain olsem 'expansion' na 'contract' bilong bilding, na planti taim i nidim 20%-35% 'displacement level' bilong inapim muvmen bilong straksa we i kamap bikos long senis bilong temperaja.

Wantaim wok bilong kamapim gut ol standet bilong sevim pawa, ol 'high-pefomens dua na windo 'sealant' i wok long go long liklik 'modulus', 'elasticity' i antap, i no bagarapim envairomen, na i stap longpela taim. Sapos ol i makim na yusim ol 'sealant' long stretpela pasin, dispela i no inap long daunim tru pawa bilong bilding na mekim ol dua na windo i stap longpela taim, tasol tu i ken givim gutpela na gutpela ples insait long haus bilong ol manmeri i stap insait long haus. Em i wanpela bikpela teknikel samting bilong wokim ol nupela bilding.
