Kuita Hunhu uye Kuongororwa Kwekushandisa kweStructural Sealant

Structural sealant ishongedzo yepamusoro{{0}yekuvaka inonyanyo shandiswa kubatanidza nekunamira zvivakwa zvakaita semadziro emaketeni, magonhi, mahwindo, nemagirazi anoisa insulating. Basa rayo guru nderekupa nguva yakareba-rutsigiro rwakatsiga rwemuchina uye kuvhara mvura, kuve nechokwadi chekusimba uye kuchengetedzeka kwezvivakwa zvekuvaka.

 

Panyaya yekushanda, zvisimbiso zvezvimiro zvine adhesion yakanakisa, kuramba mamiriro ekunze, uye elasticity. Ivo vanogona kubatanidza zvakasimba zvinhu zvakasiyana-siyana, segirazi, simbi, dombo, uye macomposites, uye kuramba vakagadzikana munzvimbo dzakaoma sekuchinja kwekushisa, kuratidzwa kweUV, uye kukukurwa kwemhepo nemvura. Zvisimbiso zvemazuva ano zvinogara zvichishandisa silicone kana yakagadziridzwa polyurethane masisitimu, ichipa yakanakisa yekutamisa kugona, kuchinjika kudiki deformation uye kudzivirira kutsemuka kana kudonha kunokonzerwa nezvinhu zvakaita sekuwedzera kwekupisa uye kuputika uye kudengenyeka.

Panyaya yekushandiswa, zvisimbiso zvezvimiro zvinoshandiswa zvakanyanya kubatanidza girazi kune aruminiyamu mafuremu mumaketeni emadziro masisitimu, kuvhara mipendero yegirazi inodzivirira, uye magonhi ekudzivirira mvura nemahwindo. Semuyenzaniso, muzvivakwa zvakakwirira-zvinamiso zvezvimiro zvinoita basa rakakosha pakusunganidza magirazi epanera kune rinotsigira furemu, uye simba rawo rinobata zvakananga kuchengetedzeka kwese kwemadziro eketeni. Uyezve, muzvivako zvakagadzirirwa, zvisimbiso zvezvigadziro zvinoshandiswawo kuvhara majoini ezvikamu zvakagadzirirwa, kuvandudza simba reimba yechivako uye kudzivirira mhepo.

Kusarudza iyo yakakodzera dhizaini sealant inoda kutariswa kwemamiriro ekunze, substrate mhando, uye mutoro zvinodiwa. Semuyenzaniso, masimbi anodzivirira mamiriro ekunze-anodzivirirwa nesilicone sealants akakodzera kushandiswa kumamiriro ekunze akanyanya, ukuwo marengenzi ekunze-anopora ari akakodzera kune mamwe asingade kukoromoka kune simbi substrates.

Mune ramangwana, sezvo kudiwa kwezvivakwa zvakasvibira nekuchengetedza simba nekuchengetedzwa kwezvakatipoteredza kuchikura, kuchengetedzwa kwenzvimbo kushoma-VOC (volatile organic compound) magadzirirwo ezvivharo anozove maitiro ari kukura, zvichiwedzera kuchengetedzwa kwechivako nekusimba.
