Kawngkhar leh kawngkhar sealant hi building tui tlak lohna, sound insulation leh energy humhalhna atana thil pawimawh tak a ni. Hman dik chuan kawngkhar leh kawngkhar dam chhung nasa takin a ti rei thei a, nunphung pawh a tichangtlung thei bawk. A hnuaia tarlan te hi professional hman dan tur tips te an ni:

 

1. Surface Preparation: Thianghlim leh vawt hi a pawimawh hle.

A hnawih hmain a joint-ah leivut, oil leh sealant hlui awm zawng zawng chu uluk takin silfai thin ang che. Zu emaw specialized cleaner emaw hman a tha. Substrate chunglam chu a vawt vek tur a ni. Humid condition hian sealant a curing tha lo thei a, bond strength a ti tlem thei bawk. Metal emaw plastic emaw chungah mold release agents awm leh awm loh enfiah la, adhesion tihchak nan a tul chuan sandpaper tlem te te hmangin enfiah bawk ang che.

2. Adhesive thlan dan: A hman dan tur nena inmil

Environment a zirin sealant chi thlang rawh: Silicone sealant hi kawngkhar leh window tam zawk tan a tha (an khaw lum leh khaw vawt laka invenna sang tak avangin), polyurethane sealants hi joint flexible tak tak (joint expansion leh contraction tawk fo thin ang chi) tan a tha a, MS modified sealants hian environment friendliness leh adhesion balance (indoor hman atan a tha) a pe bawk.

Hmun zau tak chu section hrang hrangah hnawih tur a ni a, sealant vawi khat meter 1 aia sei lo hnawih tur a ni a, chu chuan a tlakbuak loh nan leh a lan dan a nghawng tha lo thei ang.

4. Tihdam leh enkawl dan

Silicone adhesive hi a dam kim theih nan darkar 72 chhung (25 degree-ah) a ngai a ni. Hemi hun chhung hian tui nena inhnaih loh tur. A tir lama tuiah a awm chuan a chunglam a var thei a, hei hi thil pangngai tak a ni. Mahse, adhesive layer thuk zawk, tihdam lohte chu tuiah a awm chuan a thatna a hloh ang. Thlasik laiin curing time chu ti sei la, low-temperature formula hmang rawh.

A chunga kan sawi tak technique te hi thiam taka hman chuan sealant hman tangkai theihna a tipung ang. Joint enfiah fo (kum tin rawt) leh a hun taka siamthat hian leak leh energy hloh te chu a tha thei ang bera ven theih a ni.
