Door leh Window Sealant hmanraw pawimawh ber ber leh a nihna

Door leh window sealants hi construction industry-a sealing material pawimawh tak a ni a, an hnathawh hian kawngkhar leh window-a boruak luh theihna, tui tlak lohna leh a chhe thei lo chu direct-in a nghawng a ni. Sealant-a thil pawimawh ber hian a hman theih tur environment, bond strength leh service life te a tichiang a ni. Thil hman tlanglawn tak takte chu silicone, polyurethane, acrylic, leh polysulfide rubber te an ni.

 

Silicone sealant hi kawngkhar leh kawngkhar sealing material hman lar ber a ni a, khaw lum leh khaw vawt laka invenna tha tak, UV laka invenna, leh hun rei tak chhunga elasticity tha tak a pe a ni. A thil tel ber polydimethylsiloxane hi -50℃atanga 200℃thlenga lumnaah a nghet a, hei vang hian boruak hrang hrangah a tha hle. Silicone sealant hian in sakna thil tam zawk (glas, metal, leh ceramics ang chi)-ah a nghet hle a, tar chakna pawh a do thei a, hei vang hian kawngkhar leh kawngkhar inzawmna hun rei tak chhunga seal-na atan duhthlanna lar tak a ni.

Polyurethane sealant erawh chu a bond strength sang tak leh abrasion resistance tha tak a neih avangin hriat hlawh tak a ni a, hei vang hian kawngkhar leh window structure-a movement nasa tak nei tan a tha hle. A tlangpuiin polyol leh isocyanate polymer atanga siam a ni a, elastic recovery tha tak a nei a, temperature inthlak danglamna avanga kawngkhar leh window inzai leh tihtlem danah a insiamrem thei a ni. Mahse, polyurethane sealants hi moisture lakah a sensitive a, a hman laiin humidity control khauh tak a ngai a ni. UV light rei tak an awm chuan an sen thei bawk.

Acrylic sealants hi a man a tlawm zawk a, a vawt nghal vat a, hei vang hian in chhung kawngkhar leh window atan emaw, hun rei lote-sealing mamawhna atan emaw a tha hle. Acrylic polymer atanga siam a ni ber a, adhesion leh decorative property tha tak tak an pe a, mahse khaw lum leh khaw vawt laka invenna tha lo tak an nei a, hun rei tak chhung pawn lama hman chuan cracking emaw powder emaw an nei awlsam hle.

Polysulfide rubber sealants hi high-end construction-ah hman a ni ber. Air permeability hniam tak leh oil resistance tha tak an pe a, hei vang hian airtightness sang ber mamawhna atan an tha hle.

Kawngkhar leh kawngkhar sealant atana hmanraw hrang hrangte hian a thatna leh that lohna a nei vek a. I thlan dawnin, kawngkhar leh kawngkhar te chu hun rei tak-a seal theih nan boruak dinhmun, application mamawh leh budget te ngaihtuah thin ang che.
