Ubude Obude Be-PU Sealant: Kuzohlala Isikhathi Esingakanani?

Ukuphila isikhathi eside kwe-PU sealant kuwukukhathazeka okuvamile phakathi kwabathengi abafuna ukuvikela indawo yabo ezintweni zezulu, umswakama, nokuguga. Ukuqonda ukuthi i-PU sealant ingahlala isikhathi esingakanani kubalulekile kubanikazi bezindlu, osonkontileka, nabathandi be-DIY ukuthi benze izinqumo ezinolwazi mayelana nezidingo zabo zokuvala. Kulesi sihloko, sizohlola ngokuningiliziwe izici ezithonya impilo ende ye-PU sealant futhi sinikeze imininingwane yokuthi singanweba kanjani isikhathi sayo sokuphila.

Izinto Ezithinta Isikhathi Eside Se-PU Sealant

Ukuphila isikhathi eside kwe-PU sealant kungathonywa izici ezihlukahlukene ezithinta ukusebenza nokuqina kwayo ngokuhamba kwesikhathi. Esinye sezici ezibalulekile yikhwalithi ye-sealant ngokwayo. Ama-sealant ekhwalithi ephezulu e-PU aklanyelwe ukumelana nezimo zemvelo ezinzima futhi anikeze ukuvikeleka okuhlala isikhathi eside. Ama-sealant ashibhile, anekhwalithi ephansi angehlisa izinga ngokushesha futhi adinge ukuphinda kusetshenziswe kaningi.

Esinye isici esibalulekile yindlela yokufaka isicelo kanye nokulungiswa kwendawo. Ukulungisa kahle indawo ngaphambi kokufaka i-PU sealant kubalulekile ukuze kuqinisekiswe ukunamathela okuphezulu nokuphila isikhathi eside. Ukulungiswa kwendawo enganele noma amasu okufaka isicelo angafanele kungaholela ekuhlulekeni kwe-sealant ngaphambi kwesikhathi kanye nokuncipha kwesikhathi sokuphila.

Izici zemvelo ezinjengokuchayeka emisebeni ye-UV, ukushintshashintsha kwezinga lokushisa, namazinga omswakama nakho kungathinta impilo ende ye-PU sealant. Ukuchayeka elangeni isikhathi eside kungabangela ukuwohloka kwe-UV, okuholela ekushintshashintsheni kombala, ukuqhekeka, nokulahlekelwa ukunwebeka ku-sealant. Ukushintsha kwezinga lokushisa okudlulele kungase futhi kuthinte ukuguquguquka kwe-sealant kanye nezakhiwo zokunamathela, okungase kubeke engcupheni ukuphila kwayo isikhathi eside.

Ukuhlola Ubude Obude be-PU Sealant

Ukunquma isikhathi eside se-PU sealant, abakhiqizi benza izivivinyo ezihlukahlukene ukuze bahlole ukusebenza kwayo ngaphansi kwezimo ezahlukene. Ukuhlolwa kwesimo sezulu okusheshisiwe kulingisa ukuchayeka isikhathi eside elangeni, umswakama, nokuhlukahluka kwezinga lokushisa ukuze kuhlolwe ukumelana kwe-sealant kuzinto zemvelo. Lezi zivivinyo zisiza abakhiqizi ukuthi benze izincomo ngesikhathi sokuphila esilindelekile se-sealant ezinhlelweni ezahlukene.

Ukuhlolwa kwenkundla kungenye indlela esetshenziswa ukuhlola ubude besikhathi se-PU sealant ezimeni zomhlaba wangempela. Ngokuqapha ukusebenza kwe-sealant ezindaweni zangempela ngokuhamba kwesikhathi, abakhiqizi bangaqoqa idatha ebalulekile yokuthi i-sealant imelana kanjani nesimo sezulu, ukuguga, namanye amandla angaphandle. Lolu lwazi lubalulekile ekwenzeni ngcono ukwakheka kwezigxivizo ze-PU kanye nokuthuthukisa ukuqina kwazo.

Ukunweba Ubude Obude be-PU Sealant

Ukwandisa isikhathi eside se-PU sealant, ukunakekelwa okufanele nokunakekelwa kubalulekile. Ukuhlolwa okuvamile kwezindawo ezivaliwe kungasiza ekuhlonzeni noma yiziphi izimpawu zokuguga noma zokonakala kusenesikhathi, okuvumela ukulungiswa ngesikhathi kanye nokusetshenziswa kabusha njengoba kudingeka. Ukuhlanza izindawo ezivalekile njalo ngensipho namanzi kungasiza ukulondoloza ukubukeka nokusebenza kwe-sealant ngokuhamba kwesikhathi.

Ukwengeza, ukusebenzisa ama-primers ahambisanayo kanye nezesekeli ze-sealant kungathuthukisa ukunamathela nokuqina kwe-PU sealant. Ama-Primers asiza ukukhuthaza ukuhlangana okungcono phakathi kwe-sealant ne-substrate, okuqinisekisa ukuvikeleka okuhlala isikhathi eside kumswakama, amakhemikhali, nezinye izinto ezilimazayo. Ukusebenzisa amathuluzi namasu afanele ngesikhathi sokufaka isicelo nakho kungaba nomthelela empilweni ende ye-PU sealant futhi kusize ukuzuza imiphumela emihle.

Izinkinga Ezivamile Ezithinta Ukuphila Isikhathi Eside Se-PU Sealant

Naphezu kokuqina kwayo nokumelana nesimo sezulu, i-PU sealant ingaba lula ezindabeni ezithile ezingathinta ukuphila kwayo isikhathi eside. Inkinga eyodwa evamile ukuklama okuhlangene okungalungile, okungaholela ekunyakazeni ngokweqile, ukucindezeleka, nokwehluleka kwe-sealant ngokuhamba kwesikhathi. Ububanzi obuhlanganyelwe obunganele, ukujula, noma isilinganiso se-sealant-to-substrate singalimaza ikhono le-sealant lokwamukela ukunyakaza nokugcina ukunamathela.

Enye inkinga ukungcoliswa kwe-sealant ngesikhathi noma ngemuva kokufakwa. Uthuli, ukungcola, uwoyela, nezinye izinhlayiya zangaphandle kungakhinyabeza inqubo yokwelapha ye-sealant futhi kunciphise ukunamathela kwayo ku-substrate. Ukuze uvimbele ukungcola, kubalulekile ukuhlanza nokulungisa izindawo ezingaphezulu ngendlela efanele ngaphambi kokufaka i-sealant kanye nokuvikela i-sealant emfucumfucwini ngesikhathi sokuphulukisa.

Isifinyezo

Sengiphetha, ubude besikhathi se-PU sealant buncike ezintweni ezahlukahlukene njengekhwalithi ye-sealant, indlela yokufaka isicelo, izimo zemvelo, kanye nezinqubo zokunakekela. Ngokuqonda lezi zici nokuthatha izinyathelo ezifanele zokuvikela nokugcina i-sealant, ungaqinisekisa ukusebenza kwayo okuhlala isikhathi eside nokuqina. Ukuhlolwa okuvamile, ukulungiswa kwendawo efanele, nokulungiswa ngesikhathi kubalulekile ekwandiseni isikhathi eside se-PU sealant nokwandisa izinzuzo zayo zokuvikela. Kungakhathaliseki ukuthi uvala ikhaya lakho, ihhovisi, noma indawo yezimboni, ukukhetha i-PU sealant yekhwalithi ephezulu nokulandela izinqubo ezingcono kakhulu zokufaka isicelo nokunakekelwa kubalulekile ukuze uthole imiphumela emihle nokuvikelwa okuhlala njalo.
