Yini i-polyurethane sealant esetshenziselwa?
Polyurethane sealantIsetshenziselwa ukubekwa uphawu kanye nokugcwalisa izikhala, ukuvimbela amanzi nomoya ukuthi kungangeni amalunga, ukuhlalisa ukunyakaza kwemvelo kwezinto zokwakha, kanye nokwenza ngcono ukukhalaza okubukwayo. I-Silicone ne-polyurethane izinhlobo ezimbili ezisetshenziswa kabanzi zama-sealants.
Kuyinto impahla eguquguqukayo esetshenziswa kakhulu ekwakheni nasekukhiqizweni kwezicelo ezahlukahlukene ngenxa yokunamathela kwayo okuhle, ukuguquguquka nokuqina. Nazi ezinye zezinto zokusebenzisa okuyinhloko zePu Sealant:
Ukuhlanganisa amalunga nezikhala:Imvamisa isetshenziselwa ukusangula amalunga nezikhala ezintweni zokwakha, njengaphakathi kwamawindi nezicabha, ezinhlakeni zokhonkolo, kanye nokulungiswa kwamapayipi ukuvikela ukungena komoya kanye namanzi.
Isimo sezuluAma-polyurethane banatali ahlinzeka ngesithiyo esivimbela isimo sezulu, abenze balungele izinhlelo zokusebenza zangaphandle lapho ukuvezwa umswakama, ukuguquguquka kokukhanya kwe-UV, nokushintshana lokushisa kuyinto ekhathazayo.
Izicelo ezinamathela:Ngaphezu kokubekwa uphawu, ama-polyurethane sealants nawo angasebenza njengama-adhesives aqinile wokubopha izinto ezahlukahlukene, kufaka phakathi izinkuni, insimbi, ingilazi namapulasitiki.
Ukusetshenziswa kwezimoto:Embonini yezimoto, ama-polyurethane sealants asetshenziselwa ukubopha izimboni kanye nokubopha ama-windvields, amaphaneli omzimba, nezinye izingxenye ukuthuthukisa ubuqotho besakhiwo nokuvimbela ukuvuza kwamanzi.
Ukwakhiwa nokulungiswa kabusha:Zisetshenziswa kabanzi ekwakheni uphawu lokubopha uphawu ophahleni, i-siding, kanye nezisekelo, kanye nasemisebenzini yokulungisa kabusha ukugcwalisa izikhala nemifantu ezindongeni nasezinyaweni.
Izicelo zasolwandle:Ama-polyurethane sealants alungele izindawo zasolwandle, lapho zisetshenziselwa ukusangula nezingxenye zebhondi ezikebheni nakwesinye isikhathi samanzi, ukuhlinzeka ngokumelana namanzi nosawoti.
Izicelo zezimboni:Ezimweni zezimboni, izisetshenziswa ze-polyurethane zisetshenziselwa imishini yokuvalwa uphawu, imishini, kanye neziqukathi ukuvikela ukuvuza nokuvikela ezintweni zezemvelo.
I-Junbond JB50 ukusebenza kwezithuthi ezinamathela
I-JB50 Polyurethane WindScreen AdhesiveIngabe amandla aphezulu, i-modulus ephezulu, uhlobo olunamathela khona i-polyurethane windscreen adhesive, ingxenye eyodwa, okuqukethwe okuqinile okunomswakama, akukho zinto eziyingozi, akukho zinto eziyingozi ezikhiqizwa ngesikhathi sokuphulukisa, akukho ukungcoliswa kwezinto eziyisisekelo. Ingaphezulu lipendiwe futhi lingahlanganiswa ngopende nezinkomba ezahlukahlukene.
Ingasetshenziselwa umhlangano oqondile wama-WildSreens wezimoto kanye nezinye izibopho eziphakeme eziphakeme.
Ingabe i-polyurethane sealant ingcono kune-silicone?
Ikhwalithi ephezulu kanye nemvelo eqinile ka-Polyurethane SALANAS ibanikeza ithuba elincane ngaphezulu kwezindawo ezihlala isikhathi eside ze-silicone.
Kodwa-ke, ukuthi i-polyurethane sealant ingcono kune-silicone sealant incike kwisicelo esithile nezidingo. Nayi eminye umehluko osemqoka okufanele ucabangele:
Adhesion: I-Polyurethane SealantsNgokuvamile zinokunamathela okungcono kokuhlukahluka okubanzi kwezindawo ezibanzi, kufaka phakathi izinkuni, insimbi, nokhonkolo, ukuzenza zilungele izinhlelo zokusebenza ezifunwa kakhulu.
Ukuvumelana nezimo:Womabili la maSalants anikeza ukuguquguquka, kepha i-polyurethane ivame ukuba nokunwebeka, ukuvumela ukuba ibambe ukunyakaza okungcono, okunenzuzo ezindaweni ezibheke ekwandisweni nasekuqedweni.
Ukuqina:Ama-polyurethane sealants ahlala isikhathi eside futhi amelana nokuvezwa, amakhemikhali, nokuvezwa kwe-UV, okwenza babe nelungele izinhlelo zokusebenza zangaphandle nezimboni.
Ukumelana Amanzi:Zombili lezi zinhlobo zinikeza ukumelana kwamanzi okuhle, kepha ama-polyurethane ama-sealan ajwayele ukwenza kangcono ezimweni ezimanzi futhi angakwazi ukubekezelela ukuvezwa isikhathi eside kumswakama.
Isikhathi Sokuvuka:Ama-sealants abicone avame ukwelapha ngokushesha kune-polyurethane sealants, engaba yinzuzo kumaphrojekthi azwela isikhathi.
Ama-Aesthetics:Ama-sealants abicone atholakala ngohlobo olubanzi lwemibala futhi angajabulisa ubuhle bezicelo ezibonakalayo, kanti ama-polyurethane seatance angadinga ukupenda ukubukeka okuqediwe.
Ukumelana Nezinga Lokushisa: Ama-Silicone Sealants ngokuvamile anokumelana okungcono okushisa okuphezulu, okwenza balungele izinhlelo zokusebenza ezivezwa ukushisa okwedlulele.

Izindawo ezisetshenziswayo zomoya, njll. Izindawo ezisetshenziswayo zifaka ingilazi, i-aluminium alloy (kufaka phakathi upende), njll.
Ingabe i-polyurethane sealant ihlala njalo?
I-Polyurethane Langant yaziwa ngokuqina kwayo kanye nokunamathela okuqinile, i-polyurethane ye-polyurethane caulk yethu ihlala njalo, ilwa nezinyembezi, futhi igcina ukusebenza kwayo noma ngabe ivezwa imisebe ye-UV.
I-Polyurethane Sealant iqeda ukuqeda kanzima, okuqinile. Uma welaphekile, kwakha isibopho esiqinile nesiqinile esingamelana nezingcindezi ezahlukahlukene nezimo zemvelo. Kodwa-ke, iphinde igcine ukuguquguquka okuthile, okuvumela ukuthi kwamukele ukunyakaza ezintweni zokwakha ezilukhuni. Le nhlanganisela yobulukhuni kanye nokuvumelana nezimo kwenza i-polyurethane sealant ilungele izinhlelo eziningi eziningi.
