Iyini i-Polyurethane Sealant esetshenziselwa yona?
I-polyurethane sealantisetshenziselwa ukuvala nokugcwalisa izikhala, ukuvimbela amanzi nomoya ukuthi kungangeni emalungeni, kuvumele ukunyakaza kwemvelo kwezinto zokwakha, kanye nokuthuthukisa ukubukeka. I-Silicone ne-polyurethane yizinhlobo ezimbili ezisetshenziswa kakhulu zama-sealant.
Iwumsebenzi oguquguqukayo ovame ukusetshenziswa ekwakhiweni nasekukhiqizeni izinhlelo zokusebenza ezahlukahlukene ngenxa yokunamathela kwayo okuhle kakhulu, ukuguquguquka, nokuqina. Nazi ezinye zezindlela eziyinhloko ezisetshenziswa ngayoi-sealant:
Ukuvala Amalunga Nezikhala:Ivamise ukusetshenziselwa ukuvala amajoyinti kanye nezikhala ezintweni zokwakha, njengaphakathi kwamafasitela nezicabha, ezakhiweni zikakhonkolo, nasezindaweni ezizungezile zamapayipi amanzi ukuze kuvinjelwe ukungena komoya namanzi.
Ukuvikela isimo sezulu:Ama-polyurethane sealants ahlinzeka ngokuvimbela ukumelana nesimo sezulu, okuwenza alungele ukusetshenziswa kwangaphandle lapho ukuchayeka kumswakama, ukukhanya kwe-UV, nokuguquguquka kwezinga lokushisa kuwukukhathazeka.
Izicelo zokunamathela:Ngaphezu kokubekwa uphawu, ama-polyurethane sealants angasebenza futhi njengezinamatheliso eziqinile zokuhlanganisa izinto ezihlukahlukene, okuhlanganisa ukhuni, insimbi, ingilazi, namapulasitiki.
Ukusetshenziswa Kwezimoto:Embonini yezimoto, ama-polyurethane sealants asetshenziselwa ukubopha nokuvala amawindi omoya, amaphaneli omzimba, nezinye izakhi ukuthuthukisa ubuqotho besakhiwo nokuvimbela ukuvuza kwamanzi.
Ukwakha Nokuvuselela:Asetshenziswa kakhulu ekwakheni ukuze kuvalwe ophahleni, emaceleni, nasezisekelweni, kanye nasezinhlelweni zokuvuselela ukuze kugcwaliswe izikhala nemifantu ezindongeni naphansi.
Izicelo Zasolwandle:Ama-polyurethane sealants afanele izindawo zasolwandle, lapho asetshenziselwa khona ukuvala nokubopha izingxenye ezikebheni nakwezinye izikebhe zamanzi, okunikeza ukumelana namanzi nosawoti.
Izicelo zezimboni:Ezilungiselelweni zezimboni, ama-polyurethane sealants asetshenziselwa ukuvala imishini, izinto zokusebenza, neziqukathi ukuvimbela ukuvuza nokuvikela ngokumelene nezici zemvelo.
I-JUNBOND JB50 Ukusebenza Okuphezulu Okunamathelayo Kwezimoto Ze-Polyurethane
I-JB50 polyurethane windscreen adhesiveingamandla aphezulu, i-modulus ephezulu, i-adhesive yohlobo lwe-polyurethane windscreen adhesive, ingxenye eyodwa, ukwelapha umswakama wegumbi, okuqukethwe okuqinile, ukumelana nesimo sezulu esihle, ukunwebeka okuhle, azikho izinto eziyingozi ezikhiqizwa ngesikhathi nangemva kokwelashwa, akukho ukungcoliswa kwezinto eziyisisekelo. Ingaphezulu liyapendeka futhi lingagcotshwa ngamapende ahlukahlukene kanye nama-coatings.
Ingasetshenziselwa ukuhlanganiswa okuqondile kwezikrini zomoya zezimoto nokunye ukubopha okuqinile kwesakhiwo.
Ingabe I-Polyurethane Sealant Ingcono Kune-Silicone?
Ikhwalithi ephezulu kanye nemvelo eqinile yama-polyurethane sealants ibanika inzuzo encane ngaphezu kwezakhiwo ezihlala isikhathi eside ze-silicone.
Kodwa-ke, ukuthi i-polyurethane sealant ingcono kune-silicone sealant kuncike ekusetshenzisweni okukhethekile kanye nezidingo. Nakhu okuhlukile okubalulekile okufanele kucatshangelwe:
Ukunamathela: I-polyurethane sealantsngokuvamile babe nokunamathela kangcono endaweni ebanzi ebanzi, okuhlanganisa ukhuni, insimbi, nokhonkolo, okubenza bafanelekele izinhlelo zokusebenza ezinzima kakhulu.
Ukuvumelana nezimo:Womabili ama-sealants anikeza ukuguquguquka, kodwa i-polyurethane ijwayele ukunwebeka, ivumela ukuthi ibambe ukunyakaza kangcono, okuzuzisayo ezindaweni ezingaphansi kokunwetshwa nokufinyela.
Ukuqina:Ama-polyurethane sealants ngokuvamile ahlala isikhathi eside futhi amelana nemihuzuko, amakhemikhali, nokuchayeka kwe-UV, okuwenza alungele ukusetshenziswa kwangaphandle nasezimbonini.
Ukumelana Namanzi:Zombili izinhlobo zinikeza ukumelana kwamanzi okuhle, kodwa ama-polyurethane sealants ngokuvamile enza kangcono ezimeni ezimanzi futhi angakwazi ukumelana nokuchayeka isikhathi eside kumswakama.
Isikhathi sokuphumula:Ama-Silicone sealants ngokuvamile elapha ngokushesha kunama-polyurethane sealants, okungaba inzuzo kumaphrojekthi azwela isikhathi.
Ubuhle:Ama-Silicone sealants atholakala ngemibala eminingi ebanzi futhi angathandeka kakhulu ezinhlelweni zokusebenza ezibonakalayo, kuyilapho ama-polyurethane sealants angase adinge ukupenda ukuze kubukeke sekuphelile.
Ukumelana Nezinga Lokushisa: Ama-silicone sealant ngokuvamile anokumelana okungcono nezinga lokushisa eliphezulu, okuwenza afanelekele izinhlelo zokusebenza ezivezwe ukushisa okukhulu.
I-JUNBOND JB16 Polyurethane Windshield Sealant
I-JB16 iyingcina yengxenye eyodwa ye-polyurethane ene-viscosity ephakathi nendawo ukuya phezulu kanye namandla aphakathi ukuya phezulu. Ine-viscosity emaphakathi kanye ne-thixotropy enhle yokwakha kalula. Ngemuva kokwelashwa, inamandla okubopha okuphezulu kanye nezakhiwo ezinhle zokubeka uphawu eziguquguqukayo.
Isetshenziselwa ukuvala uphawu okunwebekayo okunamathelayo okuhlala njalo kwamandla okubopha okuvamile, okufana ne-windshield bonding yezimoto ezincane, ukubopha isikhumba sebhasi, ukulungisa i-windshield yemoto, njll. Ama-substrates asebenzayo ahlanganisa ingilazi, i-fiberglass, insimbi, i-aluminium alloy (okuhlanganisa nopende), njll.
Ingabe i-Polyurethane Sealant Ihlala Njalo?
I-polyurethane sealant yaziwa ngokuqina kwayo nokunamathela kwayo okuqinile, I-polyurethane caulk sealant yethu eguquguqukayo ingunaphakade, ayizweli izinyembezi, futhi igcina ukusebenza kwayo noma ngabe kuvezwe emisebeni ye-UV.
I-polyurethane sealant yoma kuze kube sekugcineni okuqinile, okuqinile. Uma seselaphekile, kwakha isibopho esiqinile, esiqinile esingamelana nezingcindezi ezihlukahlukene nezimo zemvelo. Kodwa-ke, iphinda igcine ukuguquguquka okuthile, ukuyivumela ukuthi ikwazi ukuthwala umnyakazo ezintweni ezivalayo. Le nhlanganisela yokuqina nokuguquguquka yenza i-polyurethane sealant ifanele uhla olubanzi lwezinhlelo zokusebenza.
