wuute gi am ci digganté sealant silicone neutre ak adhésif structurel silicone medium

I. wuute ci composition ak mecanisme de cure
1. Silikon bu amul benn boor:

- Li ci gëna am solo: hydroxyl-polidimetilsiloksan bu jeex. Dafay wér ci dealcoolisation ci di naan guus gi ci air bi, daal di forme elastomer bu yomba laxasu su wéree.

- Dafay wér ndànk (tack-diir bu amul àpp lu tollu ci 30-60 simili, wér gu mat sëkk dafay jël 24-72 waxtu), moo tax mu baax ci aplikaasioŋ yi soxla soppi barab.

- Amul benn asid te du yàq substrat yu melni wen wala weer. pH bi daa jege neutre (6,5 ba 7,5).

2. Colle structurel silicone moyen:

- Dafay yokk silan wala plastifikatër yuñ soppee ngir sos module bu kawe (module elastik bu ëpp wala bu tollu ci 0.4 MPa) liiñ buy lëkkaloo ginaaw bimu ñor. Yenn produit yi dañu am sertifikaasu ASTM C1184.

- Dafay gëna gaaw (20{5}}40 simili) ak dooley lëkkaloo bu rëy (dooley traction Lu ëpp wala lu tollu ci 0.7 MPa, xoolal GB 16776-2005), moo tax mu mëna jëfandikoo ci liggéey yuy porte sargal.

II. Tegtale ci liggéey ak jëfandikoo
1. Màndarga mekanik yi:

- Sealant silicone neutre yi dañuy am doole ci traction bu tollu ci 0.5-1.0 MPa ak guddaay bu tollu ci 200%-300%, moo tax ñu mëna tëj joint dynamique yi (lu melni bërëb yi am ci diggante buntu yi ak palanteer yi).

- Adhésif structurel silicone medium dañuy am doole ci traction bu ëpp 1.0 MPa, ak yenn doole yu kawe yuy yegg ba 1.5 MPa (lu melni Baiyun SS622). Ñu ngi leen sos ngir ñu mëna lëkkale ay mbir yu melni kuur yu am rido weer ak xeer wu waw wu ñuy weer.

2. Resistance ci klimaa bi ak tàngoor wi:

- Ñoom ñaar ñépp dañuy xeex UV-, waaye adesif yu silikon yu yam yi ñoo gëna am tàngoor wu gëna gudd (-40 degre ba 150 degre, soo koy méngale ak -50 degre ba 120 degre ci adesif silikon yu amul benn boor).

Kol silikon bu amul benn boor moo gëna bàyyi xelam ci impermeabilizaasioŋ ak baña yàqu (mu méngoo ak GB/T 14683-2017), waaye kol yiñ defar dañu wara jàll ci test sismik (lu melni JIS A5758).

3. Aplikaasioŋ yiñ gëna xam:

- Kol silikon bu amul benn sikk: Impermeabilisation ak tëjukaayu duus, grouting ci carreaux, ak tëjukaayu joint tuyo yi.

- Kol structurel silicone bu yam: Kuur yu kawe yu am rido weer, lëkkaloo kaadaru salle jant bi, ak dooleel arbre ascenseur bi.

III. Moytu yi ci jëfandikoo gi
1. Balaa ngay jëfandikoo adhésif silicone neutre, danga wara raxas surface substrat bi ngir moytu diw bu mëna gàllankoor adhésion bi. Kol yiñ defaree tabax dañuy laaj substrat bu waw ak jëfandikoo primer (ci misaal, aluminium dafay laaj paj mu amul fenn).

2. Kol yi ñuy tabax dañu wara jaar ci test ngir xam ndax mën nañu ànd (ñu sukkandikoo ci ASTM C1087) ngir moytu ñu am reaction chimik ak ay mbir yuñ laal.

Tegtale bi am ci kaw dafay wane ni, doonte ñoom ñaar ay adhésif silicone organik lañu, seen mébet ci jëmmal ak seeni màndarga dañu wuute lool. Jëfandikukat yi dañu wara tànn benn ci seeni soxla.
