Ongororo Yemisimboti yekuisa Chisimbiso uye Mashandisirwo Emusuwo uye Window Sealant

Sechinhu chakakosha chinoshanda muindasitiri yekuvaka, musuwo uye mahwindo sealants 'musimboti basa nderokuwana chisimbiso, kudzivirira mvura, uye kusapinda mhepo pamajoini kuburikidza nekuita kwemuviri nemakemikari. Nheyo yavo yekushanda inonyanya kuenderana neiyo synergistic maitiro ezvivakwa zvezvinhu uye dhizaini yekugadzira.

 

Panyama, masisitimu anoita mvura kana kunamira-senge asati arapika, achizadza zvakazara tumaburi tudiki (kazhinji 3-20mm) pakati pemafuremu egonhi nemahwindo uye madziro nemagirazi, zvichigadzira muviri wakatambanuka. Mushure mekurapa, zvinhu izvi zvinogadzira muchinjiko-wakabatana chimiro, uchipa kusimba kunogara kwenguva refu uye kuchinjika kune majoini kutamiswa kunokonzerwa nekushanduka kwetembiricha (±30 madhigirii), kushanduka kwemwando, uye kumanikidzwa kwemhepo (splacement capacity inodarika 25%). Iyi elastic deformation inovimbisa kuwirirana kunoenderana pakati pechisimbiso interface uye inovhara nzira dzekupinda dzemhepo nemvura yemvura.

Iyo kemikari yekuisa chisimbiso meshini inotsamira pane dhizaini yekugadzira zvinhu. Silicone sealants inowana kusamira kwemamiriro ekunze kuburikidza nesimba rebhondi repamusoro reSi-O mabhondi (inenge 452 kJ/mol). Simba rawo rakaderera (ringaita 20-24 mN/m) rinodzinga mamorekuru emvura uye rinodzivirira kuchembera kweUV. Polyurethane sealants, kune rumwe rutivi, anoita hunyoro mumhepo kuti aumbe mabhondi eurea kuburikidza nemapoka eisocyanate, achigadzira yakasimba-inochinjika inetiweki chimiro chinopa yakakwirira-kusimba kwekubatana uku uchichengetedza zviri pakati nepakati. Zvimwe zvigadzirwa zvepamusoro-soro zvinosanganisira hydrophobic fillers (senge silica) kana antimicrobial agents kuti awedzere kusimba.

Mafafitera nemadhonhi emazuva ano anonamidza zvinofanirwa kuzadzisa zvinodiwa nemhoteredzo, neforoma yakaderera-VOC (volatile organic compound) inova iyo inonyanya kukosha. Kusarudza chisimbiso chakakodzera kunoda kutariswa kwakadzama kwemhando yesubstrate (semuenzaniso, aruminiyamu alloy, PVC), nharaunda yekushanda (nzvimbo dzakanyorova/dzakaoma), uye mamichina ekurodha mamiriro. Kunyatsovhara kushanda kunoitwa kuburikidza nehurongwa hwekushandisa (semuenzaniso, single-ijekiseni repfuti yechikamu kana maviri-kusanganisa zvinhu).
