I-Sika ngumthengisi ohamba phambili kwihlabathi jikelele we-sealants, i-adhesives, kunye neenkqubo zokuthintela amanzi ezisebenza kakuhle zokwakha, kushishino, kwiimoto, nakwiiprojekthi zeziseko zophuhliso. Ngophando lwezinto kunye namava okusetyenziswa angaphezu kwenkulungwane, i-Sika sealants yaziwa ngokubanzi ngokusebenza kwayo okugqwesileyo, umgangatho ozinzileyo, kunye nokuqina okuthembekileyo. Zisetyenziswa kakhulu kwizakhiwo zokuhlala, uyilo lwezorhwebo, ubunjineli bokwakha, imveliso yemizi-mveliso, kunye nothutho. Iimpawu eziphambili zemveliso ye-Sika sealants zishwankathelwe apha ngezantsi.
Okokuqala, izinto zokutywina zeSika zineukuthamba okuphezulu kunye nokukwazi ukuhambahambaUninzi lweemveliso lunokuziqhelanisa nokususwa kwamalungu ukusuka kwi-±25% ukuya kwi-±50%, nto leyo enokwanelisa ngokupheleleyo ukwanda kunye nokucutheka okubangelwa kukutshintsha kobushushu, ukungcangcazela kwesakhiwo, kunye nokuhlaliswa kwesiseko kwizakhiwo. Nokuba zisetyenziswa ixesha elide, aziyi kuqhekeka, zixobule, okanye zilahlekelwe bubuthambile, nto leyo eqinisekisa ukuba isiphumo sokutywina sihlala ixesha elide.
Okwesibini, izitywini zeSika zineukunamathela okuphezulu kwihlabathi liphelaZinokubopha ngokuqinileyo kwizinto ezininzi zokwakha, kuquka ikhonkrithi, ilitye, umthi, i-aluminium alloy, intsimbi engatyiwayo, iglasi, iplastiki, kunye nemiphezulu yokugquma. Iimveliso ezininzi kuthotho lweSikaflex® ziyaphumelelaukunamathela okungenasiseko, nto leyo eyenza kube lula kakhulu amanyathelo okwakha, iphucula ukusebenza kakuhle kokwakha, kwaye iqinisekisa ukubopha okuzinzileyo naphantsi kweemeko ezinzima zokusingqongileyo.
Okwesithathu, izitywini zeSika zineukumelana nemozulu okuhle kakhulu kunye neempawu zokulwa nokwaluphalaZinokumelana okunamandla kwe-UV, ukumelana nobushushu obuphezulu nobuphantsi, kwaye zinokugcina ukusebenza okuzinzileyo ixesha elide kwiindawo ezingaphandle ezibonakala ngaphandle. Aziyi kuba buthathaka, zibe tyheli, okanye zicolwe ngenxa yelanga, imvula, ingqele, okanye ubushushu, kwaye zinobomi obude kakhulu kunezivali eziqhelekileyo.
Okwesine, izinto zokutywina zeSika zibonelelaukuthintela amanzi okuthembekileyo kunye nokusebenza okungangeni moya. Ngenxa yesakhiwo esixineneyo se-colloid kunye nokufunxwa kwamanzi okuncinci, zinokuthintela ngempumelelo imvula, ukufuma, umoya, kunye nokungena kothuli. Zisetyenziswa kakhulu ekuvaleni iingcango neefestile, kwiindawo zodonga zangaphandle, eluphahleni, kwigumbi lokuhlambela, ekhitshini, nakwezinye iindawo ukuthintela ukuvuza kwamanzi, ukungunda, kunye nokuvuza komoya, kunye nokuphucula ukusebenza kakuhle kwamandla kunye nentuthuzelo yesakhiwo.
Okwesihlanu, uninzi lwezitywina zeSika luneukupeyintwa kakuhle kakhuluIngakumbi iimveliso ze-polyurethane, zinokudityaniswa ngokugqibeleleyo neepeyinti ezisekelwe emanzini kunye nepeyinti ezisekelwe kwioyile. Emva kokupeyinta, aziyi kubonisa ukungalingani, ukubila, okanye ukutshintsha kombala, zihlangabezana neemfuno eziphezulu zobuhle bokuhombisa izakhiwo zanamhlanje.
Okwesithandathu, ii-sealants zeSika zigxile kwiukhuseleko lokusingqongileyo, impilo, kunye nokhuselekoUninzi lweemveliso azina-VOC ininzi, azinavumba liphantsi, azina-isocyanate, azinatyhefu, kwaye azinazo iintsimbi ezinzima eziyingozi. Ziyahlangabezana nemigangatho yesatifikethi se-EU REACH, i-RoHS, kunye nezakhiwo eziluhlaza, nto leyo ezenza zikhuseleke ukusetyenziswa kumagumbi okulala, ezibhedlele, ezikolweni, kwii-kindergartens, nakwezinye iindawo zangaphakathi.
Okwesixhenxe, izitywina zeSika zineukumelana kakuhle kweekhemikhaliZiyakwazi ukumelana neekhemikhali zemihla ngemihla, iisepha, iioyile, kunye nee-asidi ezibuthathaka kunye nee-alkali, kwaye azilula ukuzibola okanye ukuzibola. Olu phawu luzenza zisetyenziswe kakhulu kwiindawo zokusebenzela zoshishino, kwiigaraji, kwiikhikhini, ezibhedlele, nakwezinye iindawo ezineemfuno eziphezulu zococeko.
Okwesibhozo, izitywini zeSika zineukusebenza kakuhle kolwakhiwoKulula ukuzikhupha, azigobi kwiindawo ezithe nkqo, zinesantya esiphakathi sokuzilungisa, kwaye zifanelekile kulwakhiwo lobuchwephesha nokusetyenziswa ekhaya. Zingakhiwa ngemipu yeglue eqhelekileyo, zisebenza kakuhle kwaye zisebenza kakuhle.
Okwesithoba, ii-sealants zeSika zineukusetyenziswa ngokubanzi kunye nokwahlukahluka. USika uphuhlise i-silicone, i-polyurethane, i-hybrid polymer, kunye nezinye iiseti zeendawo ezahlukeneyo zokusetyenziswa. Iiseti ze-silicone zifanelekile kwiindawo zangaphandle ezihlala ixesha elide kunye neendawo ezinomswakama ophezulu; iiseti ze-polyurethane zifanelekile kwiindawo ezifuna amandla aphezulu kunye nokupeyintwa; iiseti ze-hybrid zidibanisa izibonelelo zokhuseleko lokusingqongileyo, ukuthamba okuphezulu, kunye nokunamathela okunamandla.
Okweshumi, izitywini zeSika zineukuthembana okuphezulu kophawu kunye nozinzo lomgangathoNjengophawu oluphambili lwezixhobo kwihlabathi liphela, iimveliso zikaSika ziphantsi kolawulo olungqongqo lomgangatho kunye novavanyo lokusebenza, kwaye ziyahambelana nemigangatho yamazwe ngamazwe efana ne-ASTM kunye ne-ISO. Zithenjwa ngabayili bezakhiwo, abakhi kunye nabanini bezindlu kwihlabathi liphela.
Ukuqukumbela, ii-sealants zeSika zidibanisa ukuthamba okuphezulu, ukunamathela okuqinileyo, ukumelana nemozulu, ukuthintela amanzi, ukhuseleko lokusingqongileyo, ukuqina, kunye nokulula kokwakha. Zinokuhlangabezana neemfuno zeemeko ezahlukeneyo zokusebenza ezinzima kwaye zibonelele ngokhuseleko lokutywina oluhlala ixesha elide noluzinzileyo kwizakhiwo nakwiimveliso zoshishino. Nokuba kukuphucula ikhaya ngaphakathi, ukwakhiwa kwezakhiwo zorhwebo, okanye iiprojekthi ezinkulu zeziseko zophuhliso, ii-sealants zeSika zikhetho ezikumgangatho ophezulu ezinokusebenza okuthembekileyo kunye nobomi benkonzo ende.
