Ingabe uyazi? Ebusika, i-structural sealant nayo izofana nengane, yenza intukuthelo encane, ngakho yiziphi izinkinga ezizobangela?
1.Ukuqiniswa kwe-sealant yesakhiwo
Ama-sealant esakhiwo azojiya kancane kancane futhi abe uketshezi oluncane njengoba izinga lokushisa lincipha. Ku-sealant yesakhiwo sezingxenye ezimbili, ukuqina kwe-sealant yesakhiwo kuzokwandisa ukucindezela komshini weglue futhi kunciphise ukukhishwa kwe-sealant yesakhiwo. Kuma-sealant esakhiwo sengxenye eyodwa, i-structural sealant iyaqina, futhi ingcindezi yesibhamu seglue ukuze sikhiphe i-sealant yesakhiwo siyakhula, futhi ukusebenza okwenziwa ngesandla kungase kuzwe kudla isikhathi futhi kukhandla.
Isixazululo: Uma ungekho umthelela ekusebenzeni kahle kokwakhiwa, ukujiya kwezinga lokushisa eliphansi kuyinto evamile, futhi azikho izinyathelo zokuthuthukisa ezidingekayo. Uma kuthinta ukusebenza kahle kokwakhiwa, ungacabangela ukukhulisa izinga lokushisa lokusetshenziswa kwe-structural sealant noma usebenzise ezinye izindlela zokushisa ezisizayo, njengokugcina isivalo sesakhiwo endaweni yokushisisa noma ene-air-conditioning kusengaphambili. Faka ukushisa endaweni yokusebenzela ye-gluing ukwandisa izinga lokushisa lendawo yokunamathisela. Ngaphezu kwalokho, ungakhetha amathuluzi eglue afanelekile, njengezibhamu zeglue ezisetshenziswayo ezine-high thrust, izibhamu ze-pneumatic glue, izibhamu zeglue zikagesi, njll.
2.I-Weathering sealant bulges - ukubukeka okungalingani
Ebusika, umehluko wezinga lokushisa phakathi kwemini nobusuku uvame ukuba mkhulu. Uma isetshenziswa odongeni lwamakhethini ephaneli ye-aluminium, isivalo esimelana nesimo sezulu sijwayele ukuqhuma. Isizathu esiyinhloko siwukuthi ijubane lokuphulukisa le-sealant elimelana nesimo sezulu liya lihamba kancane endaweni yokushisa ephansi, futhi isikhathi esidingekayo ukuze ingaphezulu liphulukise ukujula okwanele sizoba side. Ngaphezulu kwe-sealant engamelana nesimo sezulu Lapho ukujula kweglue kungelaphekanga ngokwanele, uma ububanzi be-glue seam buhluka kakhulu (lokhu kuvame ukubangelwa ukunwetshwa kokushisa nokwehliswa kwephaneli), ingaphezulu i-glue seam izothinteka futhi ukungalingani kuzovela. Ngemuva kokuthi i-adhesive seam enendawo engalingani ekugcineni iphulukisiwe, ingaphakathi layo liqinile, hhayi elingenalutho, elingeke lithinte ukusebenza kokuvala isikhathi eside kwe-sealant ephikisana nesimo sezulu, kodwa kuthinte kuphela ukubukeka kwe-adhesive seam.
Ngemva kobusika, indawo enkulu iyaphola, izinga lokushisa liphansi, futhi umehluko wokushisa phakathi kwasekuseni nakusihlwa mkhulu. Ngenxa ye-coefficient enkulu yokunwetshwa komugqa wento, udonga lwamakhethini ephaneli ye-aluminium luwohloka kakhulu ngezinga lokushisa. Ngaphansi kwezimo ezingenhla zokwakhiwa kwe-sealant yesakhiwo, kunethuba elithile lokuthi izihlanganisi zeglue zodonga lwamakhethini e-aluminium panel zizoqhuma.
Isixazululo:
1.Khetha i-glue enesivinini sokuphulukisa esisheshayo, esinganciphisa ngokusesilinganisweni inkinga yokubhodla kwesivalo esimelana nesimo sezulu.
2.Uma i-deformation yesihlobo sokuhlanganiswa kweglue inkulu kakhulu ngenxa yomswakama ophansi noma umehluko wokushisa, usayizi ohlangene weglue, njll., Kunconywa ukukhetha eyodwa noma ngaphezulu yezindlela ezilandelayo zokwakha.
a) Thatha izinyathelo ezifanele ze-shading, njengokuvikela i-scaffolding ngamanetha angangeni uthuli, ukuze amapaneli angavezwa ngokuqondile elangeni, anciphise izinga lokushisa lamaphaneli, futhi anciphise ukubola kwamalunga okubangelwa ukuhluka kwezinga lokushisa.
b).Zama ukuhlela ukunamathiswa emini, futhi ugweme ukunamathisela ekuseni nakusihlwa.
c) .Sebenzisa indlela yokusetshenziswa kweglue yesibili (okungukuthi, uma kukhona umthungo weglue we-concave ekusetshenzisweni kokuqala kweglue, ungelapheka izinsuku ezingu-2 kuya kwezingu-3, futhi ngemva kokuba u-elasticity, ungqimba lweglue lwengezwa phezulu).
