Structural Sealant dah dan leh Technical Point pawimawh tak tak te

Structural sealants hi construction leh industrial sector-a connection leh sealing atana hmanraw pawimawh tak a ni. Installation dik tak hian structures te durability leh safety a nghawng nghal vek a ni. A hnuaia tarlan te hi standard installation process leh structural sealants atana technical point pawimawh tak tak te a ni.

 

1. Lei chunglam Pretreatment

Installation hmain substrate chunglam chu uluk takin tifai la, oil, leivut leh thil loose te chu paih chhuak rawh. Metal emaw concrete chunglam tan chuan solvent (isopropyl alcohol ang chi) hmanga phihfai a tha a, sanding tool hmanga roughness tihpun a tha a, chu chuan bond strength a ti tha zawk a ni. Moisture emaw mold emaw a awm chuan a chunglam chu a vawt vek tur a ni a, disinfected a ngai bawk.

2. Joint Design leh Primer hman dan tur

Design mamawh angin uniform joint (a tlangpuiin 6-12mm wide) buatsaih rawh. Depth-to-width ratio 1:1 atanga 2:1 a nih a tha. Low-surface-energy materials (polytetrafluoroethylene ang chi) tan chuan dedicated primer dah hmasa la, minute 5-10 vel vawt turin dah la, chu chuan bond tha tak a nei thei ang.

3. Sealant mix leh Applying

Component sealant pahnih-te chu a dik taka mix tur a ni a, boruak bubble a tlakbuak loh nan uluk taka stir tur a ni. Single-component adhesive hi direct-a hman theih a ni. Glue gun bik hmangin adhesive joint te chu speed mumal takin fill la, continuous, full, leh bubble-free surface a awm theih nan. Vertical surface tan chuan a hnuai atanga chunglam thlengin glue hnawih la, a sagging loh nan.

4. Trimming leh Curing

I hnawih zawh chuan hmanraw bik (scraper ang chi) hmangin adhesive chu a hrual, a hrual angin trim rawh. A tam lutuk chu tihfai vat tur a ni. Curing time hi ambient temperature leh humidity hian a nghawng a; initial strength chu darkar 24 chhungin a thleng tlangpui a, ni 7 chhungin full cure a awm thei bawk. Hemi hun chhung hian pawn lam thil tihbuai emaw, tui tlakchhamna emaw pumpelh tur a ni.

Fimkhur tur: A hnawihtute chuan vun emaw mit emaw a inhnaih loh nan protective gloves leh goggles an vuah tur a ni. Eng atanga hla takah sealed container-ah dah tur a ni. A hmun lum leh vawt tur chu 5-25℃a ni .

Heng step te hi khauh taka zawm chuan structural sealant chu a thawk tha ber ang a, building structure dam chhung pawh a ti rei ang.
