A hman dik chuan sealant bonding performance leh service life a nghawng nghal vek a ni. A hnuaia tarlan te hi kawngkhar leh kawngkhar sealant hman dan tur standard operating procedure a ni.

 

1. Leihnuai inbuatsaihna

A hnawih hmain kawngkhar leh kawngkhar frame leh bang inzawmna chu uluk takin tifai la, leivut, oil emaw, thil hrual emaw a awm loh nan. A chunglam chu a vawt a, moisture-free a nih ngei ngei tur a ni. A tul chuan solvent (isopropyl alcohol ang chi) hmangin phihfai la, i kal hmain a hmin vek turin dah rawh.

2. Seam buatsaih dan tur

Kawngkhar leh kawngkhar lian leh te a zirin gap width dik tak (a tlangpuiin 5-10mm) phalsak rawh. Sealant compression tam lutuk ven nan foam rod emaw backing strip emaw hmangin gap chu thuk takin fill rawh. Sealant a luh loh nan leh lakchhuah harsa a nih loh nan backing strip chu gap chhungah a fit tha tur a ni.

3. Sealant hman dan tur

Sealant chu dedicated sealant gun-ah load la, gap chhungah chuan a rualin squeeze rawh. Sealant i hnawih hian 45℃angle vawng reng la, chutiang chuan a kal zel tur a ni a, a full surface a awm theih nan, bubble emaw breakpoint emaw a awm lo ang. Corner emaw complex area emaw tan chuan sealant hi batch hrang hrangin hnawih la, a chunglam chu trim leh shape rawh.

4. Trimming leh Curing

Scraper emaw i kut zungtang emaw, tuiah thun (sahbawn tui a tha zawk) hmangin sealant chunglam chu tifai la, substrate nen inthlak danglamna mumal tak siam rawh. Sealant hi darkar 24 chhung (ambient temperature leh humidity a zirin) a cure tlangpui. Hetih lai hian sealant nena inhnaih emaw, tui nena inhnaih emaw loh tur.

Fimkhur tur: 1.1.

Substrate nena inmil sealant thlang rawh (entir nan, silicone sealant hi material tam zawk tan a tha a, mahse polyethylene ang chi low-surface-energy materials erawh chu pumpelh tur a ni).

A hmanna tur temperature chu 5-40℃a ni a, humidity pawh a hniam tur a ni.

Sealant chu vun nen a inzawm chuan solvent hmangin silfai nghal tur a ni. Mit a luh chuan tui thianghlim hmangin silfai nghal la, damdawi lam pan rawh.

A hman dan dik tak chuan kawngkhar leh kawngkhar sealing nasa takin a tichangtlung thei a, building dam chhung pawh a ti rei thei a ni.
