Izici Zokusebenza Nokuhlaziywa Kwesicelo Se-Structural Sealant

I-Structural sealant iyinto{0}}esebenza kahle kakhulu yokwakha esetshenziselwa ikakhulukazi ukubopha nokuvala izakhiwo ezifana nezindonga zamakhethini, izicabha, amafasitela, nezingilazi zokuvikela ukushisa. Umsebenzi wayo oyinhloko ukuhlinzeka{2}}isikhathi eside, usekelo lwemishini oluzinzile kanye nokuvala uphawu okungenamanzi, ukuqinisekisa ukuqina nokuphepha kwezakhiwo zokwakha.

 

Ngokusebenza, ama-sealant esakhiwo anokunamathela okuhle kakhulu, ukumelana nesimo sezulu, nokunwebeka. Bangakwazi ukuhlanganisa ngokuqinile izinto ezihlukahlukene, njengengilazi, insimbi, itshe, nezinhlanganisela, futhi bahlale bezinzile ezindaweni ezinokhahlo njengokushintshashintsha kwezinga lokushisa, ukuchayeka kwe-UV, nokuguguleka komoya nemvula. Ama-sealant esakhiwo sesimanje ngokuvamile asebenzisa i-silicone noma amasistimu e-polyurethane alungisiwe, anikeza amandla amahle kakhulu okususwa, ajwayelana nokuwohloka okuncane kwesakhiwo futhi avimbele ukuqhekeka noma ukuchitheka okubangelwa izici ezinjengokwanda nokufinyela okushisayo nokuzamazama komhlaba.

Mayelana nokusetshenziswa, ama-sealant esakhiwo asetshenziswa kakhulu ukuhlanganisa ingilazi kumafreyimu e-aluminium ezinhlelweni zodonga lwamakhethini, ukuvala imiphetho yengilazi evikelayo, kanye neminyango namafasitela okuvikela amanzi. Isibonelo, ezakhiweni eziphakeme-eziphakeme, ama-sealant esakhiwo adlala indima ebalulekile ekuhlanganiseni amaphaneli engilazi kuhlaka olusekelayo, futhi amandla awo athinta ngokuqondile ukuphepha kukonke kodonga lwamakhethini. Ngaphezu kwalokho, ezakhiweni ezakhiwe ngaphambili, izinsimbi zokuvala izinsimbi zesakhiwo nazo zisetshenziselwa ukuvala amalunga ezingxenye ezakhiwe, ukuthuthukisa ukonga kwamandla wesakhiwo kanye nokungangeni komoya.

Ukukhetha i-sealant yesakhiwo efanele kudinga ukucatshangelwa kwezimo zemvelo, uhlobo lwe-substrate, kanye nezidingo zomthwalo. Isibonelo, ama-silicone sealant amelana nesimo sezulu esiphezulu{1}}alungele ukusetshenziswa esimweni sezulu esibi kakhulu, kuyilapho ama-sealant angathathi hlangothi{2}}okwelapha afaneleka kakhulu ezinhlelweni ezingadingi ukugqwala kuma-substrates ensimbi.

Ngokuzayo, njengoba isidingo sezakhiwo eziluhlaza nokongiwa kwamandla kanye nokuvikelwa kwemvelo sikhula, ama-sealant esakhiwo angavumelani nemvelo aphansi-i-VOC (volatile organic compound) azoba umkhuba okhulayo, okuqhubekisele phambili ukuthuthukisa ukuphepha nokusimama kwesakhiwo.
