Amazi yo Gukiza Igihe cya Silicone itagira aho ibogamiye

I. Ihame rya siyansi yamazi - Gukiza kashe ya Silicone itagira aho ibogamiye
Silicone idafite aho ibogamiye ikiza ikoresheje ubuhehere - ikiza. Ibyingenzi byingenzi, silane polymer, ikora hydrolysis - reaction ya kondegene hamwe nubushuhe (H₂O) mukirere, bigakora imiterere ya -. Iyi nzira igabanijwemo ibyiciro bitatu:

1. Shakisha - Igihe cyubusa: Filime ya elastike ikora hejuru yikimenyetso, ifata iminota igera kuri 30 (dogere 25/50%). Irakoraho ariko ntabwo ari igitutu - irwanya.

2. Umuti wimbitse: Amazi agomba kwinjira imbere murwego rwa kashe, bisaba amasaha agera kuri 24 kuri milimetero yubugari (isoko yamakuru: ASTM C920-2021).

3. Umuti wuzuye: Kugera ku mbaraga zanyuma bisaba byibuze amasaha 48. Igihe cyihariye kirebwa nimpamvu zikurikira:

- Ubushuhe bw’ibidukikije: Gukiza bitinda munsi ya 40%, mugihe ubushyuhe buri hejuru ya 70% bushobora kugabanya igihe cyo gukira 20%.

- Ubushyuhe: Gukiza inshuro ebyiri kuri buri dogere 10 igabanuka (urugero, amasaha 72 kuri dogere 15).

II. Kwihutisha gukira no gukemura ibibazo
1. Uburyo bwihuta:

- Shira igihu cyamazi kugirango wongere ubuhehere (irinde kwibiza mu buryo butaziguye).

{0}

2. Ibibazo bisanzwe:

{0} kugenzura ingano ya spray.

- Kunanirwa kwa Adhesion: Amavuta yubushyuhe cyangwa ubushyuhe buri munsi ya dogere 5 bisaba kwitegura no kongera igihe cyo gukira.

III. Ibyifuzo byumwuga nibyifuzo byo gusaba
Dukurikije ibizamini byakozwe na Sealant Council (SSC), igihe cyo gukiza ibicuruzwa bitandukanye bya silicone itabogamye biratandukana munsi ya 10%. Ibyifuzo:

{0} Kurwanya amazi byiyongereyeho 50% nyuma yo gukira.

- Irinde iminsi yimvura yo gusaba hanze; guhura nimvura mbere yo gukira birashobora gutuma colloid yabyimba cyangwa igacika.
