Tlhahlobo ea Melao-motheo ea ho Tiisa le Litšebeliso tsa Monyako le Window Sealant

Joalo ka thepa ea bohlokoa e sebetsang indastering ea kaho, ts'ebetso ea mantlha ea mamati le lifensetere ke ho fihlela ho tiisa, ho thibela metsi, le ho thibela moea ho manonyeletso ka tšebetso ea 'mele le ea lik'hemik'hale. Molao-motheo oa bona oa ho sebetsa o thehiloe haholo-holo holim'a phello ea synergistic ea thepa ea thepa le moralo oa moralo.

 

Ka 'mele, li-sealants li metsi kapa li peista-joaloka pele li ka phekoloa, li tlatsa ka botlalo likheo tse nyane (ka tloaelo 3-20mm) pakeng tsa liforeimi tsa lemati le lifensetere le lebota le likhalase, ho etsa 'mele o sarolohang. Ka mor'a ho phekoloa, thepa e hlahisa{4}mohaho o hokahantsoeng, o fanang ka botsitso ba nako e telele le ho ikamahanya le ho falla ha manonyeletso ho bakoang ke ho fetoha ha mocheso (± 30 degrees), ho fetoha ha mongobo, le khatello ea moea (bokhoni ba ho falla bo fetang 25%). Deformation ena ea elastic e tiisa hore ho kopana ho tsitsitseng pakeng tsa sebopeho sa tiiso le ho thibela litsela tsa ho phunyeletsa bakeng sa moea le metsi a metsi.

Mochine oa ho tiisa lik'hemik'hale o itšetlehile ka moralo oa tlhahiso ea thepa. Li-silicone sealants li khona ho mamella boemo ba leholimo ka matla a holimo a bond ea Si-O bond (hoo e ka bang 452 kJ/mol). Matla a tsona a tlase (hoo e ka bang 20-24 mN/m) a leleka limolek'hule tsa metsi 'me a thibela botsofali ba UV. Ka lehlakoreng le leng, li-polyurethane sealants li sebetsana le mongobo moeeng ho theha li-urea bonds ka lihlopha tsa isocyanate, ho theha marang-rang a thata-o fana ka tlamo e phahameng-ea matla ha u ntse u boloka ho tenyetseha ha maemo. Lihlahisoa tse ling tsa boleng bo holimo li boetse li kenyelletsa li-filler tsa hydrophobic (joalo ka silica) kapa li-antimicrobial agents ho matlafatsa ts'ebetso ea nako e telele.

Lisebelisoa tsa sejoale-joale tsa lifensetere le mamati le tsona li tlameha ho fihlela litlhoko tsa tikoloho, ka mokhoa o tlase-VOC (volatile organic compound) e bang tsona tse ka sehloohong. Ho khetha sekoahelo se nepahetseng ho hloka hore ho nahanoe ka botlalo mofuta oa substrate (mohlala, motsoako oa aluminium, PVC), tikoloho ea ts'ebetso (libaka tse mongobo / tse omeletseng), le maemo a ho kenya mochine. Ts'ebetso e nepahetseng ea ho koala e fihlelleha ka ts'ebetso ea leano (mohlala,{7}}ente e le 'ngoe ea lithunya kapa tse peli{8}}motsoako oa metsoako).
