Kuyini i-PU Sealant Futhi Kungani Kubalulekile?

Izinto zokuvala zibaluleke kakhulu ekuphepheni nasekuhlaleni isikhathi eside kwemisebenzi yokwakha, yezimoto, neyezimboni. Ama-PU sealants kanye nama-PU foam sealants ayimikhiqizo emibili evame kakhulu. Womabili amalungu omndeni we-polyurethane, okuyiqembu lama-polymer aguquguqukayo kakhulu, anamathela kahle, futhi aqinile impela.

A I-PU sealant isetshenziselwa ukugcwalisa izikhala nemifantu ukuze yenze isithiyo esinamandla nesiguquguqukayo ngokumelene nomoya, amanzi, nokudlidliza. Ngakolunye uhlangothi, i-PU foam sealer iyakhula ngemva kokufakwa ukuze igcwalise izikhala, igcine ukushisa ngaphakathi, futhi ivimbele amandla ekuphumeni.

Lapha sizoxoxa ngendlela le mikhiqizo esebenza ngayo, izinzuzo nezingozi zayo, ukusetshenziswa kwayo, imininingwane yayo yobuchwepheshe, nokuthi kungani abantu emhlabeni wonke bethemba izixazululo ze-PU ze-Shuode.

I-PU Sealant vs I-PU Foam Sealant: Uyini Umehluko

I-PU sealan t kanye ne -PU foam sealant zombili zenziwe nge-polyurethane; nokho, zenza izinto ezihlukile.

• Isivali se-PU   (ngesimo se-paste noma se-bead) : Faka ngokushesha ezinhlanganisweni noma emithungweni. Iqina ibe yinto efana nerabha, elula. Isetshenziswa kakhulu ekuvaleni izimoto, ekufakeni i-glazing, kanye nasekunwebeni amalunga.
• I-PU Foam Sealant (I-Expanding Foam) : Ikhishwa emathinini acindezelwe noma kuma-spray rig. Ingakhula ibe yivolumu yayo yoketshezi ephindwe ka-30 kuya ku-60 ukuze ivale imigodi. Ivame ukusetshenziswa ekushiseni, ozimele bamafasitela, kanye nokugcwalisa izikhala.

Izinhlobo ze-PU Sealants

• Ama-PU Sealants e-1-Component : Ayelapha ngomswakama, kulula ukuwasebenzisa, futhi asebenza ezindaweni eziningi zokwakha.
• Izivalo ze-PU zezingxenye ezimbili : Ngaphambi kokusebenzisa, hlanganisa i-resin ne-hardener. Yenza izinto zome ngokushesha futhi zisebenze kangcono.

Uzosebenzisa nini?

• Uma udinga ukuguquguquka nokunyakaza kwamalunga, khetha i-PU sealant .
• Uma ufuna ukugcwalisa imigodi noma ukwenza ukushisa kwakho nomsindo kube ngcono, sebenzisa i-PU foam sealan t.

Indlela Ama-PU Sealants Asebenza Ngayo

Uma ama-polyol nama-isocyanate esabela, enza ama-polyurethane. Ezinhlelweni eziphulukiswe umswakama, amaqembu e-isocyanate akhululekile asabela nomhwamuko wamanzi ukuze akhe ukuxhumana kwe-urea, okwenza inethiwekhi eqinile yokunwebeka.

I-ejenti yokuvunguza noma ukusabela kuma -sealant e-PU foam kukhiqiza amabhamuza egesi, okwenza umkhiqizo ube mkhulu ngaphambi kokuba uphole ngokuphelele. Umphumela uba yizinto ze-foam ezinamaseli avaliwe noma anezimbobo. Kunikeza izinzuzo zokuvikela nokuvimbela.

Ukushisa, umswakama, kanye nosayizi wesikhala konke kuthinta ukuqina. Ukuqina kuyashesha ezindaweni ezishisayo nezimanzi kunokuba kube sezimweni ezibandayo nezomile.

Izakhiwo Eziyinhloko Zezivalo Ze-PU

Ngaphambi kokukhetha umkhiqizo, abacacisi bahlola imininingwane ebalulekile yobuchwepheshe.

• Isigaba sokungabi nesikhumba/ukungabi nama-tack: Lesi yimizuzu engama-30 kuya kwengama-90 ezindaweni ezijwayelekile. Sivimba ukungcola ukuthi kunamathele.
• Ijubane lokwelapha (Ukujula Ngosuku): Ku-23 °C kanye no-50% RH. Ngokuvamile libeka u-2–4 mm ngamahora angu-24.
• Ukuqina kwe-Shore A: 30–50. Lokho kukhombisa ukuthi iqinile kodwa isagobeka.
• Amandla Okudonsa: 1.5–3.0 MPa. Iwusizo emajoyintini omthwalo.
• Umthamo Wokushintsha: ±25–100%. Lokhu kuyahlukahluka ngohlobo.
• Ukushisa kokusetshenziswa: -40 °C kuya ku-+90 °C.
• Umphumela we-VOC: Ngemisebenzi yangaphakathi, khetha izinhlobo ze-VOC eziphansi.

Lezi zici zichaza ukuthi kungani ama-sealant e-PU ehlala eqinile kune-silicone emisebenzini eminingi yokwakha kanye neyokucindezeleka.

Ukusetshenziswa kwe-PU Sealant kanye ne-PU Foam Sealant

Ukwakhiwa Nokwakhiwa

Ukuguquguquka kwama -PU sealant kuwenza athandwe kakhulu ekwakheni. Amunca ukunyakaza kwesakhiwo futhi asekele amajoyinti okunwebeka ngenkathi ehlala engangeni manzi. Avimbela ukuvuza ezinhlelweni zodonga lwamafasitela namakhethini ngokuvala umngcele. Avikela uphahla kanye nephansi emswakama kanye nokuqhekeka ukuze kuhlale isikhathi eside.

• Izinzuzo Zokushisa:   Ama-PU foam sealants abonisa amanani aphezulu e-R. Lokho kukhulisa ukufudumala futhi kunciphisa inani lamandla asetshenziswa yizakhiwo.
• Ukonga Imali: Kuhlala isikhathi eside, ngakho-ke ukunakekelwa kuyancipha. Ukulahlekelwa amandla okuncane kusho ukunciphisa izindleko okuqhubekayo.

Imikhawulo kanye Nokucatshangelwa

Ama-sealant e-PU anikeza izinzuzo eziningi. Kodwa kufanele ufunde ukuthi ungawasebenzisa kanjani futhi uwaphathe kahle:

• Izimo Zokuphulukisa: Umswakama ophansi noma isimo sezulu esibandayo kungalibazisa inqubo yokubeka.
• Ukusethwa Komphezulu: Izisekelo ezingcolile zenza ukubopha kube nzima. Kungase kudingeke ukuhlanza nokufaka i-primer.
• Yazi ukuthi yini engcono kakhulu : Akuzona zonke izinhlobo ze-PU ezingamelana nokukhanya kwelanga. Kumaphrojekthi angaphandle, izinketho ezingamelana ne-UV zingcono kakhulu.
• Ukuphepha: Ama-sealant e-PU angaba nezinyibilikisi noma ama-isocyanate kuwo; ngakho-ke, udinga ukuqinisekisa ukuthi kunomoya owanele futhi ugqoke izimpahla zokuphepha ezifanele.
