Upende we-topcoat ovikela ukuguguleka we-polyurethaneKuvele njengesixazululo esihamba phambili ezindaweni eziningi zezimboni, zezentengiselwano, kanye nezindawo zokuhlala. Njengoba zidumile ngokuqina kwazo okumangalisayo, ukuguquguquka kobuhle, kanye nokusebenza kwesikhathi eside, lezi zingubo zokugqoka zenzelwe ukubekezelela izimo ezivame kakhulu, ukuchayeka kumakhemikhali, kanye nokucindezeleka kwemishini. Njengoba izimboni ziqhubeka nokubeka phambili ukuphepha, inhlanzeko, kanye nokusebenza kahle, izingubo zokugqoka ze-polyurethane zinikeza inketho yephansi eyinkimbinkimbi nethembekile edlula izinto eziningi ezivamile. Lokhu kuhlola okujulile kuhlanganisa izici ezihlukile, izinzuzo eziningi, izinhlelo zokusebenza ezahlukahlukene, kanye nezindlela zokufaka ezinembile zezingubo zokugqoka ze-polyurethane ezingagugi.
Izici Ezichazayo Zezimbozo Zaphansi Ezingagugi Ze-Polyurethane
Izembozo zephansi ze-polyurethane zakhiwe ngezinto ezithuthukisiwe ze-polymer, ziletha ubuso obuqinile nobuhlala isikhathi eside. Nazi izici ezivelele ezizihlukanisayo:
- Ukuqina Okumangalisayo Nokumelana Nokuguguleka
Izembozo ze-PU zisebenza kahle ezindaweni eziguga njalo ngenxa yokuhamba ngezinyawo, imishini esindayo, kanye nemishini ehambayo. Ukubekezelela kwazo okukhulu ukuguguleka kuqinisekisa ukuthi indawo ihlala ingaguquki futhi isebenza iminyaka eminingi, ihlala isikhathi eside kune-epoxy kanye nezinye iziqephu zendabuko.
- Ukumelana Okuphezulu Kwamakhemikhali
Lezi zingubo zokugqoka zihlinzeka ngokuvikelwa okuqinile emafutheni, ezincibilikisini, kuma-asidi, kuma-alkali, nakwezinye izinto ezinolaka. Lokhu kuzenza zibaluleke kakhulu ekukhiqizeni izitshalo, amalabhorethri, kanye namayunithi okucubungula ukudla lapho kuchitheka khona amakhemikhali njalo.
- Ukuguquguquka Kokushisa Nokumelana Nokuqhekeka
Ngokungafani nezinhlelo zophansi eziqinile, izembozo ze-polyurethane zigcina izinga lokunwebeka, okuzivumela ukuthi zivumelane nokukhula nokuncipha kokushisa. Lokhu kuguquguquka kusiza ukuvimbela ukuqhekeka nokwehlukaniswa, ngisho nasezindaweni ezinokushintshashintsha okukhulu kokushisa.
- Ubuhle Obungenziwa Ngokwezifiso
Itholakala ngemibala eminingi kanye nokuqedwa—kusukela ekucwebezelweni okuphezulu kanye ne-satin kuya kokungacwebezeli kanye nokuthungwa—izembozo ze-PU zingalungiswa ukuze zihambisane nanoma yisiphi isitayela sokwakha noma ubunikazi bomkhiqizo. Lokhu kuguquguquka komklamo kuzenza zifaneleke kokubili ezindaweni eziwusizo kanye nezibonakala kakhulu.
- Ukunakekelwa Okuphansi Nokuhlanza Okulula
Ubuso obungenazimbobo, obungenamthungo be-polyurethane coating bumelana nokungcola, umswakama, kanye nokukhula kwamagciwane. Ukuhlanza okuvamile kudinga kuphela ukushanela kanye nokuhlikihla ngezikhathi ezithile, kunciphisa isidingo samakhemikhali anamandla noma ukuhlanza okujulile njalo.
- Amafomula Angangcolisi Imvelo Futhi Aphansi kwe-VOC
Njengoba kugcizelelwa kakhulu ekusimeni okuzinzile, izimbozo eziningi ze-PU seziyatholakala manje ezinokuqukethwe okuphansi kwe-volitable organic compound (VOC). Lezi zinketho zinegalelo ekhwalithini yomoya wangaphakathi enempilo futhi zihambisana nemithetho eqinile yezemvelo.
- Izinzuzo Eziphelele Zezimbozo Zaphansi Ze-Polyurethane
Inani lezimbozo ze-polyurethane lidlula kude kakhulu izakhiwo zazo ezibonakalayo. Nasi ukubheka eduze izinzuzo zokusebenza kanye nezomnotho ezilethayo:
- Ukusebenza Kahle Kwezindleko Zesikhathi Eside
Nakuba izindleko zangaphambilini zingase zibe phezulu kunezinye izindlela, isikhathi eside senkonzo kanye nezidingo ezincane zokunakekelwa kwezingubo ze-PU kuholela ekongeni okukhulu ngokuhamba kwesikhathi. Ukunciphisa izindleko zokulungisa, ukushintshwa, kanye nesikhathi sokungasebenzi kuzenza zibe utshalomali oluhlakaniphile.
- Ukuphepha Okuthuthukisiwe Nokumelana Nokushelela
Ukwakheka okwenziwe ngokwezifiso kungafaka phakathi ama-aggregates noma ama-texture angasheleli, okuthuthukisa kakhulu ukubamba ezimweni ezimanzi noma ezinamafutha. Lokhu kubaluleke kakhulu ezindaweni ezifana namakhishi ebhizinisi, izindawo zokugcina impahla, kanye nama-deck echibi.
- Ukwakhiwa Okuhlanzekile Nokungenamthungo
Indlela ebushelelezi yokugqoka nge-polyurethane ayishiyi ndawo yokuqoqana kokungcola, umswakama, noma izifo ezibangelwa amagciwane. Lokhu kubalulekile emikhakheni efana nokunakekelwa kwempilo, imithi, kanye nokucubungula ukudla, lapho ukuhlanzeka kungaxoxiswana khona.
- Ukufakwa Okusheshayo Nezikhathi Zokwelapha
Izinhlelo eziningi ze-polyurethane zenzelwe ukusetshenziswa okusheshayo nokulungiswa ngokushesha, okuvumela amabhizinisi ukuthi aqale kabusha imisebenzi ejwayelekile ngaphandle kokuphazamiseka okuncane. Lokhu kuyinzuzo ebalulekile ezindaweni lapho isikhathi sokungasebenzi siholela ngqo emalini engenayo elahlekile.
- Ukuqina Kokushisa kanye Ne-UV
Ezinye izembozo ze-PU zenzelwe ukumelana nokuwohloka kwe-UV kanye namazinga okushisa aphezulu, okwenza zifanelekele ukusetshenziswa ngaphandle noma ezindaweni ezifana namabhikawozi kanye namakamelo okubhoyila lapho ukushisa kuyisici esihlala njalo.
Ububanzi Bezicelo
Izembozo ze-polyurethane ezingagugi zisetshenziswa emikhakheni eminingi ehlukahlukene, okuhlanganisa:
- Izimboni Nezimboni Zokukhiqiza
Kulungele amafektri, imigqa yokuhlanganisa, kanye nezikhungo zezokuthutha lapho phansi kutholakala khona imithwalo esindayo, ukushaywa, kanye nokuchayeka kumakhemikhali.
- Izindawo Zokuhweba Nezokuthengisa
Izitolo ezinkulu, izindawo zokubonisa, kanye nezitolo zokuthengisa ziyazuza ekuhlanganisweni kokubukeka nokusebenza kahle. Ukuphela kungenziwa ngokwezifiso ukuze kubonise ubuhle bomkhiqizo ngenkathi kumelana nokuhamba ngezinyawo okuqhubekayo.
- Izilungiselelo Zokunakekelwa Kwezempilo Nelebhu
Izibhedlela, imitholampilo, kanye namalebhu ocwaningo zidinga izitezi eziqinile futhi ezilula ukuzihlanza. Izembozo ze-PU zingachazwa ngezakhiwo zokulwa namagciwane ukuze zisekele izinqubo zokulawula ukutheleleka.
Izimboni Zokudla, Iziphuzo, kanye Nezemithi
Le mikhakha idinga izindawo ezingangenwa amanzi, okulula ukuzihlanza ezihlangabezana nemithetho eqinile yezempilo. Izembozo ze-polyurethane zinikeza isithiyo esingenamthungo, esingamunci esimelana nokuhlanza njalo kanye nezihlanzi zamakhemikhali.
- Izakhiwo Zezemfundo Nezezikhungo
Izikole, amanyuvesi, kanye nezindawo zomphakathi zidinga izitezi ezingabhekana nokugqoka kwansuku zonke ngenkathi zigcina ukubukeka okuhlanzekile nokukhangayo. Izembozo ze-PU ziyakwazi ukwenza umsebenzi, zinikeza ibhalansi yokuqina nokwakheka.
- Izindawo Zokuhlala Nezindawo Ezikhethekile
Abanikazi bezindlu baphendukela kakhulu ekuqedeni i-polyurethane yamagaraji, amagumbi angaphansi komhlaba, ama-patio, ngisho nezindawo zokuhlala zangaphakathi lapho kokubili isitayela kanye nezinto ezidingekayo kuyadingeka khona.
Inqubo Yokufaka Ochwepheshe
Ukuze kuqinisekiswe ukusebenza kahle, ukusetshenziswa kwe-polyurethane coating kumele kulandele inqubo ecophelelayo:
Ukulungiselela Okungaphezulu:
Gaya indawo ephansi bese ususa uthuli namabala kawoyela. Sika imifantu bese ususa izindawo ezingenalutho.
Isicelo se-Primer:
Hlanganisa i-epoxy primer ne-hardener ngokwesilinganiso esibekiwe. Faka ngokulinganayo ngaphandle kwamabala aphuthelwe.
Isicelo Sesendlalelo Sodaka:
Ngemva kokulungisa i-primer, hlanganisa i-epoxy intermediate coat nesihlabathi se-quartz esingu-80-120 mesh, usifake ngokusikrwela, bese ugcwalisa izindawo eziphansi;
Ukusikwa Kwesendlalelo Sesimende:
Ngemva kokupholisa, faka uthuli kahle kuze kube sezingeni elifanele, bese ushanela uthuli futhi;
Ukusetshenziswa kwejazi elithambile:
Hlanganisa i-epoxy intermediate coat ne-quartz powder ukuze wakhe ukuqina kwe-putty, bese uyifaka ngokulinganayo ukugcwalisa ama-pores amancane;
Ukusetshenziswa kwejazi elizilinganisayo:
Hlanganisa kahle izinto ezizilinganisayo ze-epoxy, zifake nge-trowel, bese kuthi ngemva kokulungiswa ngokuphelele, uhlanze bese ususa uthuli olungaphezulu;
Isicelo sesendlalelo esingagugi kakhulu:
Hlanganisa izinto ze-polyurethane ezingagugi kakhulu ngokwesilinganiso esibekiwe, zifake nge-trowel, bese uqeda nge-roller.
Upende wephansi omelana nokuguguleka we-polyurethane umelela ikhambi elisezingeni eliphezulu lezinselele zanamuhla zophahla. Ngokuhlanganisa ukuqina okuphezulu, ukuphepha, kanye nokuguquguquka kobuhle, bahlangabezana nezidingo ezishintshayo zezimboni kanye nabaninikhaya ngokufanayo. Njengoba ukugxila ezintweni zokwakha ezisimeme, ezihlanzekile, nezingabizi kakhulu kukhula, isidingo sezingubo ze-polyurethane ezisebenza kahle sikulungele ukukhula okukhulu. Kungakhathaliseki ukuthi kusefektri, esibhedlela, esitolo, noma egaraji lasekhaya, ukukhetha ingubo yephansi ye-polyurethane kuwukutshala imali kwikhwalithi, ukuphepha, kanye nenani lesikhathi eside.
