Ko Polyurethane Sealant Zvirinani Kupfuura Silicone?
Hunhu hwepamusoro uye hwakaomesesa hunhu hwepolyurethane sealants hunovapa mukana mudiki pane izvo zvinogara kwenguva refu zvivakwa zvesilicone.
Nekudaro, kana polyurethane sealant iri nani pane silicone sealant zvinoenderana neiyo chaiyo application uye zvinodiwa. Heano mimwe misiyano yakakosha yekufunga nezvayo:
Kunamatira: Polyurethane sealantskazhinji kuve nekunamira kuri nani kune yakafararira akasiyana enzvimbo, kusanganisira huni, simbi, uye kongiri, zvichiita kuti ive yakakodzera kune zvakanyanya kudiwa maapplication.
Kuchinjika:Zvose zvisimbiso zvinopa kushanduka, asi polyurethane inowanzova yakanyunguduka, ichibvumira kuti itore kufamba zviri nani, izvo zvinobatsira munzvimbo dziri pasi pekuwedzera uye kuputika.
Durability:Polyurethane sealants anowanzo kusimba uye anoshingirira kune abrasion, makemikari, uye UV kuratidzwa, zvichiita kuti zvive zvakanakira zvekunze uye maindasitiri kunyorera.
Kuramba Mvura:Mhando mbiri idzi dzinopa kumira zvakanaka kwemvura, asi ma polyurethane sealants anowanzo kuita zvirinani mumamiriro ekunyorova uye anogona kumira kuratidzwa kwenguva refu kune unyoro.
Nguva Yekudyara:Silicone sealants kazhinji inorapa nekukurumidza kupfuura polyurethane sealants, iyo inogona kuve mukana mumapurojekiti anobata nguva.
Aesthetics:Silicone sealants inowanikwa mumhando yakafara yemavara uye inogona kunyanya kunakidza kune inooneka application, nepo polyurethane sealants ingangoda pendi kuti itaridzike yapera.
Temperature Resistance: Silicone sealants inowanzova nepamusoro-tembiricha kuramba, zvichiita kuti ive yakakodzera kune maapplication akafumurwa kupisa kwakanyanya.
