I-Sika ingumhlinzeki ohamba phambili emhlabeni wonke wezithiyo zokuvala, izinamathiseli, kanye nezinhlelo zokuvimbela amanzi ezisebenza kahle kakhulu zokwakha, imboni, izimoto, kanye namaphrojekthi engqalasizinda. Njengoba ineminyaka engaphezu kwekhulu yocwaningo lwezinto ezibonakalayo kanye nesipiliyoni sokusetshenziswa, izithiyo zokuvala ze-Sika zaziwa kabanzi ngokusebenza kwazo okuhle kakhulu, ikhwalithi ezinzile, kanye nokuqina okuthembekile. Zisetshenziswa kabanzi ezakhiweni zokuhlala, ekwakhiweni kwezentengiselwano, ubunjiniyela bezokwakha, ekukhiqizweni kwezimboni, kanye nasekuthuthweni. Izici zomkhiqizo eziyinhloko zezithiyo zokuvala ze-Sika zifingqiwe ngezansi.
Okokuqala, izivalo ze-Sika zineukuguquguquka okuhle kakhulu kanye nekhono lokunyakazaImikhiqizo eminingi ingazivumelanisa nokushintshashintsha kwamalunga okungu-±25% kuya ku-±50%, okungahlangabezana ngokugcwele nokwanda nokufinyela okubangelwa ukushintsha kwezinga lokushisa, ukudlidliza kwesakhiwo, kanye nokumiswa kwesisekelo ezakhiweni. Ngisho nangaphansi kokusetshenziswa okuguquguqukayo kwesikhathi eside, ngeke ziqhekeke, zihlubule, noma zilahlekelwe ukunwebeka, okuqinisekisa umphumela wokuvala ozinzile wesikhathi eside.
Okwesibili, izivalo ze-Sika zineukunamathela okuphezulu kwendawo yonkeZinganamathelana ngokuqinile nezinto eziningi zokwakha, okuhlanganisa ukhonkolo, itshe, ukhuni, i-aluminium alloy, insimbi engagqwali, ingilazi, ipulasitiki, kanye nezindawo zokumboza. Imikhiqizo eminingi ochungechungeni lwe-Sikaflex® iyafezaukunamathela okungenasisekelo, okwenza izinyathelo zokwakha zibe lula kakhulu, kuthuthukise ukusebenza kahle kokwakhiwa, futhi kuqinisekise ukubopha okuzinzile ngisho nangaphansi kwezimo zemvelo eziyinkimbinkimbi.
Okwesithathu, izivalo ze-Sika zineukumelana nesimo sezulu okuhle kakhulu kanye nezakhiwo zokulwa nokuguga. Zinokumelana okunamandla kwe-UV, ukumelana nokushisa okuphezulu nokuphansi, futhi zingagcina ukusebenza okuzinzile isikhathi eside ezindaweni ezingaphandle ezivezwe ngaphandle. Ngeke ziqhekeke, ziphuzi, noma ziqhekeke ngenxa yelanga, imvula, amakhaza, noma ukushisa, futhi zinempilo yokusebenza edlula kakhulu izivalo ezivamile.
Okwesine, izivalo ze-Sika zinikezaukuvimbela amanzi okuthembekile nokusebenza okuvikela umoya. Njengoba inesakhiwo esiqinile se-colloid kanye nokumuncwa kwamanzi okuncane, ingavimba ngempumelelo ukungena kwemvula, umswakama, umoya, kanye nothuli. Zisetshenziswa kabanzi ekuvaleni iminyango namafasitela, ezindongeni zangaphandle, ophahleni, ezindlini zangasese, emakhishini, nakwezinye izingxenye ukuvimbela ukuvuza kwamanzi, isikhunta, kanye nokuvuza komoya, kanye nokuthuthukisa ukusebenza kahle kwamandla okwakha kanye nenduduzo.
Okwesihlanu, izivalo eziningi zeSika zineukupendwa okuhle kakhuluIkakhulukazi imikhiqizo ye-polyurethane, ingahlanganiswa kahle nopende olusekelwe emanzini kanye nopende olusekelwe ku-oyela. Ngemva kokupenda, ngeke zibonise ukungalingani, ukubhamuza, noma ukushintsha kombala, okuhlangabezana nezidingo zobuhle eziphezulu zokuhlobisa izakhiwo zesimanje.
Okwesithupha, izivalo ze-Sika zigxile ku-ukuvikelwa kwemvelo, impilo, kanye nokuphepha. Imikhiqizo eminingi ayina-VOC eningi, ayinaphunga eliningi, ayina-isocyanate, ayinabo ubuthi, futhi ayinazo izinsimbi ezisindayo eziyingozi. Ihlangabezana nezindinganiso zesitifiketi se-EU REACH, RoHS, kanye nezakhiwo eziluhlaza, okwenza iphephe ukusetshenziswa emakamelweni okulala, ezibhedlela, ezikoleni, ezinkulisa nakwezinye izindawo zangaphakathi.
Okwesikhombisa, izivalo zeSika zineukumelana okuhle kwamakhemikhali. Zingamelana namakhemikhali ansuku zonke, izihlanzi, uwoyela, nama-asidi abuthakathaka nama-alkali, futhi akulula ukugqwala noma ukuwohloka. Lesi sici sizenza zisetshenziswe kabanzi ezindaweni zokusebenzela zezimboni, emagaraji, emakhishini, ezibhedlela nakwezinye izindawo ezinezidingo eziphezulu zokuhlanzeka.
Okwesishiyagalombili, izivalo zeSika zineukusebenza okuhle kakhulu kokwakhaKulula ukuzikhipha, azigobeki ezindaweni eziqondile, zinesivinini esimaphakathi sokulungisa, futhi zilungele ukwakhiwa kobungcweti kanye nokusetshenziswa kwasekhaya. Zingakhiwa ngezibhamu zeglue ezijwayelekile, zisebenza kahle kakhulu futhi zisebenza kahle kakhulu.
Okwesishiyagalolunye, ama-sealant e-Sika anayoukusetshenziswa kabanzi kanye nokuhlukahluka. USika usungule i-silicone, i-polyurethane, i-polymer ehlanganisiwe, kanye nolunye uchungechunge lwezindawo ezahlukene zokusetshenziswa. Uchungechunge lwe-silicone lufanelekela izindawo zangaphandle nezinomswakama ophezulu isikhathi eside; uchungechunge lwe-polyurethane lufanelekela amalunga adinga amandla aphezulu kanye nokupendwa; uchungechunge lwe-hybrid luhlanganisa izinzuzo zokuvikelwa kwemvelo, ukuguquguquka okuphezulu, kanye nokunamathela okuqinile.
Okweshumi, izivalo zeSika zineukwethenjwa okuphezulu komkhiqizo kanye nokuqina kwekhwalithiNjengomkhiqizo wezinto ezibonakalayo ohamba phambili emhlabeni wonke, imikhiqizo yeSika ilawulwa ngokuqinile ikhwalithi kanye nokuhlolwa kokusebenza, futhi ihambisana nezindinganiso zomhlaba wonke ezifana ne-ASTM kanye ne-ISO. Ithenjwa ngabakhi bezakhiwo, osonkontileka, kanye nabanini bezindlu emhlabeni jikelele.
Ekuphetheni, ama-sealant e-Sika ahlanganisa ukuqina okuphezulu, ukunamathela okuqinile, ukumelana nesimo sezulu, ukuvimbela amanzi, ukuvikelwa kwemvelo, ukuqina, kanye nokulula kokwakhiwa. Angahlangabezana nezidingo zezimo zokusebenza ezahlukahlukene eziyinkimbinkimbi futhi ahlinzeke ngokuvikelwa kokuvala isikhathi eside nokuzinzile kwezakhiwo nemikhiqizo yezimboni. Kungakhathaliseki ukuthi ukuthuthukiswa kwekhaya ngaphakathi, ukwakhiwa kwezakhiwo zezentengiselwano, noma amaphrojekthi engqalasizinda amakhulu, ama-sealant e-Sika ayizinketho zekhwalithi ephezulu ezisebenza kahle futhi zihlala isikhathi eside.
