Ihlala Isikhathi Esingakanani I-PU Sealant? Ukuhlaziywa Okuningiliziwe

Isingeniso:

Ama-PU sealants asetshenziswa kabanzi ekwakheni, kwezezimoto, nakwezinye izimboni ngokunamathela kwawo okuhle kakhulu nokuqina. Kodwa-ke, abasebenzisi bavame ukuzibuza, "I-PU sealant ihlala isikhathi esingakanani?" Kulokhu kuhlaziya okuningiliziwe, sizohlola izici ezithinta isikhathi sokuphila sama-PU sealants futhi sinikeze imininingwane yokuthi singakhulisa kanjani ukuphila kwabo isikhathi eside.

Izinto Ezithinta Isikhathi Sokuphila Se-PU Sealant

Ama-PU sealants aziwa ngokuqina kwawo, kodwa izici ezimbalwa zingathinta ukuthi ahlala isikhathi esingakanani. Enye yezinto ezibaluleke kakhulu izinga le-sealant ngokwayo. Izigxivizo ze-PU ezisezingeni eliphakeme zenzelwe ukumelana nezimo ezahlukahlukene zemvelo, njengokushintsha kwezinga lokushisa, ukuchayeka kwe-UV, nomswakama. Ama-sealant ashibhile angehlisa isithunzi ngokushesha, abeke engcupheni ubuqotho bophawu.

Esinye isici esibalulekile yindlela yokufaka isicelo. Ukulungiswa okufanelekile kwendawo, izinga lokushisa elilungile lokufaka isicelo, kanye nesikhathi esanele sokuphulukisa kubalulekile ukuze isibambiso sakhe isibopho esiqinile. Ukusetshenziswa okungalungile kungaholela ekuhlulekeni kwangaphambi kwesikhathi kwe-sealant, ukunciphisa isikhathi sayo sokuphila.

Uhlobo lwe-substrate nalo ludlala indima ekunqumeni ubude besikhathi se-PU sealants. Izinto ezihlukile, njengensimbi, ukhonkolo, nokhuni, zinezilinganiso ezihlukene zokunwetshwa nokufinyela, ezingathinta ukuguquguquka kwe-sealant. Ukuhambisana phakathi kwe-sealant ne-substrate kubalulekile ukuze kuqinisekiswe isibopho esihlala njalo.

Izici zemvelo, njengokuchayeka elangeni, umswakama, namakhemikhali, zingaba nomthelela empilweni yama-PU sealants. Imisebe ye-UV ingabangela ukuwohloka kwe-sealant ngokuhamba kwesikhathi, yenze buthaka izakhiwo zayo zokunamathela. Ukuchayeka emanzini noma kumakhemikhali kungase kuholele ekuhlulekeni ngaphambi kwesikhathi kwe-sealant, ikakhulukazi ezindaweni ezingaphandle noma ezinomswakama ophezulu.

Ukugcinwa njalo nokuhlolwa kubalulekile ukuze kunwetshwe isikhathi sempilo yama-PU sealants. Ukuhlola izimpawu zokuguga, ukuqhekeka, noma ukubola kungasiza ukuhlonza izinkinga ezingase zibe khona kusenesikhathi futhi kuvimbele umonakalo omkhulu kakhulu. Ukuphinda ufake i-sealant njengoba kudingeka kungasiza ukugcina ubuqotho be-seal futhi kunwebe ubude bayo bempilo.

Ukwandisa Ukuphila Kwama-PU Sealants

Ukwandisa isikhathi sokuphila sama-PU sealants, kubalulekile ukulandela izinqubo ezihamba phambili ngesikhathi sokufakwa nokugcinwa. Ukulungiswa kahle kwendawo kubalulekile ukuqinisekisa isibopho esiqinile phakathi kwe-sealant ne-substrate. Ukuhlanza indawo engaphezulu kahle, ukususa noma yikuphi ukungcola noma okokufaka uphawu okudala, nokulungisa i-substrate uma kunesidingo kungasiza ukuthuthukisa ukunamathela nokuphila isikhathi eside.

Ukukhetha uhlobo olulungile lwe-PU sealant yohlelo oluthile nakho kubalulekile. Ama-sealant ahlukene akhelwe izinjongo ezahlukahlukene, njengokusetshenziswa kwasendlini noma ngaphandle, ukumelana nezinga lokushisa eliphezulu, noma ukuguquguquka. Ukukhetha i-sealant ehlangabezana nezidingo zephrojekthi kungasiza ekuqinisekiseni ubude bayo nokusebenza kwayo.

Amasu okufaka isicelo afanelekile, njengokusebenzisa amathuluzi alungile nokulandela imiyalelo yomkhiqizi, abalulekile ukuze isibambiso selaphe kahle. Ukugcina amazinga okushisa anconywayo kanye nomswakamo ngesikhathi sokufaka isicelo kanye nokuvumela isivalo ukuthi selaphe isikhathi esishiwo kubalulekile kubhondi ehlala isikhathi eside.

Ukuhlolwa njalo nokugcinwa kwezinsimbi ze-PU kungasiza ekuhlonzeni izinkinga kusenesikhathi futhi kuvimbele umonakalo omkhulu. Ukuqapha isimo se-sealant, ukuhlola izimpawu zokuguga noma ukuwohloka, nokufaka kabusha isitywini njengoba kudingeka kunganweba ubude bayo bempilo futhi kugcine ukusebenza kwayo ngokuhamba kwesikhathi.

Sengiphetha, isikhathi sokuphila sama-sealant e-PU singahluka kuye ngezinto ezimbalwa, okuhlanganisa ikhwalithi ye-sealant, indlela yokufaka isicelo, uhlobo lwe-substrate, izimo zemvelo, kanye nezinqubo zokunakekela. Ngokulandela izinqubo ezingcono kakhulu ngesikhathi sokufakwa nokugcinwa, ukukhetha isitywini esilungile somsebenzi, kanye nokuhlola njalo nokufaka isicelo kabusha uma kudingeka, abasebenzisi bangakwazi ukukhulisa impilo ende nokusebenza kwama-PU sealant ezinhlelweni ezihlukahlukene.
