Ukuhlaziywa Kwenqubo Yokuhlola I-Sealant

Njengento ebalulekile yokuvala emkhakheni wezokwakha, wezimoto, nezimboni, ukusebenza kwama-sealants kuthinta ngokuqondile ikhwalithi yephrojekthi nempilo yesevisi. Ukuqinisekisa ukwethembeka kwe-sealant, badinga ukuhlolwa okuphelele ngenqubo yokuhlola ehlelekile.

1. Ukulungiselela Isampula Nokwelashwa Kwangaphambili

Ngaphambi kokuhlolwa, amasampula e-sealant kufanele alungiswe ngokuya ngemininingwane ejwayelekile. Lokhu ngokuvamile kuhlanganisa ukulungiswa kwe-substrate (isb., ukuhlanzwa nokupholishwa), ukuxutshwa kwe-adhesive (izingxenye ezimbili kufanele zixutshwe ngokulinganayo ngezilinganiso ezifanele), kanye nokwakheka (isb, ukubumba umjovo noma ukunamathela). Amasampuli kufanele elashwe endaweni evamile (izinga lokushisa elingu-23±2 degree, umswakama ongu-50±5% RH) isikhathi esishiwo (isb, amahora angu-24) ukuze alingise izimo zokusetshenziswa zangempela.

2. Ukuhlolwa Kwempahla Engokoqobo

Ukuhlola Ukuqina: I-Shore A durometer isetshenziselwa ukukala ubulukhuni nokuthambile kwe-sealant eselashiwe ukuze kuqinisekiswe ukuthi ihlangabezana nezidingo zohlelo lokusebenza.

I-Tensile Adhesion: Umshini wokuhlola oqinile usetshenziselwa ukukala amandla ebhondi kanye nobude ngesikhathi sekhefu phakathi kwe-sealant ne-substrate ukuze kuhlolwe ukumelana kwayo nokugudluzwa.

I-Elastic Recovery Rate: Lokhu kulinganisa ikhono le-colloid lokululama ekuwohlokeni ngemva kokucindezelwa, okubonisa ukumelana kwayo nokukhathala phakathi{0}nokusetshenziswa kwesikhathi eside.

III. Ukuhlolwa Kwekhemikhali Nesimo Sezulu

Lokhu kuhlola kufaka ukumelana nezinga lokushisa (ukushintsha kokusebenza ngemva kokugcinwa kwezinga lokushisa eliphezulu/eliphansi), ukumelana namanzi (ukugcina ukunamathela ngemva kokucwiliswa), nokuhlolwa kokuguga kwe-UV (ukulingisa ukubaphuzi noma ukuchaki okubangelwa-ukuchayeka kokukhanya kwesikhathi eside). Ezinye izinhlelo zokusebenza ezikhethekile nazo zidinga ukuhlolwa kokuzinza kwamakhemikhali, njengokumelana nowoyela ne-solvent.

IV. Izinto Eziyingozi kanye Nezinkomba Zendawo

Ngokwemithethonqubo efanele (efana ne-GB 18583), okuqukethwe kwe-volatile organic compound (VOC), izinsalela zensimbi esindayo, kanye nokukhishwa kwe-formaldehyde kuyahlolwa ukuze kuqinisekiswe ukuhambisana nezidingo zemvelo.

V. Ukuhunyushwa komphumela nokubikwa

Yonke idatha yokuhlola kufanele iqhathaniswe namazinga kazwelonke (afana ne-GB/T 14683 ne-ASTM C920) noma amazinga emboni. Umbiko osemthethweni oqukethe izindlela zokuhlola, izimo, neziphetho uzokhishwa ukuze unikeze isisekelo sesayensi sokukhethwa kwezinto.

Ngale nqubo emisiwe, ukusebenza kwe-sealant kungaqinisekiswa ngendlela ehlelekile, kuqinisekiswe{0}}ukwethembeka kwayo kwesikhathi eside ezindaweni eziyinkimbinkimbi.
