Ol samting bilong pasim dua na windo

Olsem wanpela bikpela samting bilong ol samting bilong pasim haus, wok bilong ol dua na windo i save mekim wok bilong ol dua na windo long pasim win, wara, na strong bilong ol. Wanpela 'scientific' na 'rational formulation' i mekim na 'sealant' i gat gutpela 'adhesion', 'elasticity', na 'weather resistance', na i inapim ol samting we ol kain kain ples i laikim.

 

Ol bikpela samting bilong ol 'sealant' bilong dua na windo em wanpela 'binder', 'fillers', 'plastisaizer', 'curing agents', na ol 'additives'. Binder, em i as bilong 'sealant', i save yusim ol 'polymers' olsem 'silicone', 'polyurethane', o 'acrylates', na i save makim ol bikpela samting bilong 'sealant'. Ol 'silicone binders' i gat gutpela strong bilong sanap strong long bikpela na liklik hat na san, na dispela i mekim ol i gutpela long ol ples we i gat planti hevi. Ol 'polyurethane binders' i save givim strongpela 'adhesion' na 'elasticity', na dispela i mekim ol i gutpela long 'dynamic sealing'. Ol 'acrylate binder' i save drai hariap na i gutpela long pasim dua na windo insait long haus.

Ol i save yusim ol 'filler', olsem 'calcium carbonate', 'carbon black', o 'silica', long helpim 'sealant' long kamap strong moa, na mekim 'sealant' i kamap strong moa, na i no inap bruk, na i no inap long surik. Ol marasin bilong mekim 'sealant' (olsem 'phthalates') i save mekim 'sealant' i no inap bruk taim temperaja i senis. Ol 'curing agents' i save promotim 'cross-linking reaction' insait long ol 'sealant', na senisim ol i kamap olsem wara na kamap strongpela samting. Ol rot bilong mekim ol samting i kamap strong em olsem, ol i save mekim ol samting i kamap strong long wara (olsem, ol silikon silan) na ol i mekim ol i kamap strong long rot bilong kemikel (olsem, ol poliuretan silen).

Na tu, ol samting olsem ol 'antioxidants', 'UV absorbers', na 'thixotropic agents' inap long strongim moa yet 'sealant' long sakim olpela samting na wok gut. Ol marasin 'thixotropic' i save pasim 'sealant' long ron taim ol i putim long ol samting i sanap stret, na dispela i save mekim 'sealant' i pulap wankain.

Long tok sot, wok bilong wokim ol 'sealant' bilong dua na windo i nidim gutpela tingting long wanem kain 'base material', 'filler ratio', na 'additive selection' bilong en long mekim gutpela 'adhesion', 'elasticity', na 'durability', na dispela i mekim ol 'sealing effectiveness' na sevis laip bilong ol dua na windo i kamap gutpela moa.
