Ngaba i-Adhesives yesakhiwo ayinamanzi? Isikhokelo esiBanzi nesiSebenzayo
Ukusebenza kwamanzi okunamathela kwisakhiwo kuxhomekeke kuhlobo oluthile kunye nemeko yesicelo; ukhetho olujoliswe kuyo luyimfuneko ekutywinweni okuvuzayo okusebenzayo.
Umsebenzi ongundoqo wezinto ezincamathelayo zesakhiwo uphezulu-ukuqina kokuqina, ngelixa ukusebenza kwazo okungangeni manzi kuyahluka ngokuxhomekeke ekuyilweni. I-adhesives yesakhiwo se-silicone (efana nohlobo lwe-995) lukhetho lokuqala lokungangeni kwamanzi ngaphandle, ukubonelela ngelanga kunye nokuchasana kweqhwa, okufanelekileyo kuphahla kunye nokudibanisa iindonga zangaphandle; i-polyurethane adhesives structural adhesives (efana ne-E60HP) zenzelwe ngokukodwa iindawo ezifumileyo, ezinikezela nge-elasticity kunye nokumelana nokungunda, ezifanelekileyo kumagumbi okuhlambela kunye namakhitshi; Imizi-mveliso -izinto zokuncamathelisa zesakhiwo (ezifana ne-Loctite AA 352) zinokuphatha izixhobo eziphantsi kwamanzi, kodwa zifuna umlinganiselo ongqongqo wokuxuba. Qaphela ukuba izinto ezincamathelayo zesiqhelo zibonelela kuphela-ukhuseleko lwexeshana elifutshane kwaye ziqhele ukusilela emva kokuntywiliselwa ixesha elide emanzini.
Imeko-ukhetho olusekwe kufuneka lulandele imigaqo emithathu: Izincamathelisi zeSilicone zikhethwa kwindawo yangaphandle, zihlala zizinzile kuwo wonke amaqondo obushushu ukusuka -40℃ukuya 150℃; i-polyurethane adhesives inconywa kwiindawo ezinomswakama, njengoko zandisa kwaye zivumelane ngeetayile; Iimveliso zodidi lwemizi-mveliso- mazisetyenziswe kwindawo ezikhethekileyo (ezifana neenjini neetanki zamanzi). Imizekelo yangempela yehlabathi ibonisa ukuba umsebenzisi wasebenzisa i-Qiandinghe 9900 uhlobo lwe-silicone sealant iminyaka emithathu ngaphandle kwe-seapage yamanzi, kodwa i-substrate yonakaliswe ngexesha lokususwa ngenxa yokubambelela ngokugqithiseleyo.
Kukho iingcamango ezintathu eziphosakeleyo eziqhelekileyo kwinkqubo yokwakha: Okokuqala, ayizizo zonke izinto zokuncamathelisa zesakhiwo ezingenamanzi; umzekelo, uhlobo lwe-998 lufuna ukusetyenziswa kwe-sealant.
Okwesibini, ukucocwa okungaphelelanga kwe-substrate (okufana ne-oyile eseleyo) kunokukhokelela kwisibophelelo sobuxoki, okubangela ukuba iprojekthi ivuze kwaye ifune ukuphinda isebenze emva kweenyanga ezintathu. Okwesithathu, iileya ezincamathelayo ezishinyene ngokugqithisileyo zidla ngokuqhekeka; igumbi lokuhlambela elinye lalifuna uhlengahlengiso olupheleleyo lokuthintela amanzi emva kweenyanga ezintandathu ngenxa yokushinyene kakhulu kokuncamathelisa.
Isisombululo esiphezulu kukusebenzisa i-waterproofing edibeneyo: emva kokugcwalisa amajoyina nge-adhesive yesakhiwo, sebenzisa i-polyurethane yokugqoka, okanye uqale usebenzise i-butyl tape uze usebenzise i-adhesive, udale ukukhuselwa kabini. Olu hlobo lwesicombululo luxhaphakile kwiindawo eziphezulu{1}}eziyimfuneko ezifana namagumbi angaphantsi kunye namadama okuqubha.
Ulwakhiwo oluncamathelayo lokungangenwa kwamanzi kufuneka lulandele amanyathelo amathathu-endlela "yokukhetha, ukwakhiwa, kunye nokudibanisa." Ukuthelekisa ukusebenza kwemveliso kwimeko, ukubambelela ngokungqongqo kwiinkqubo zokusebenza, kunye nokuncedisana nezinye izinto zokungangeni manzi kubalulekile ukuze kuphunyezwe -isitywina esihlala ixesha elide kwaye ugweme ukunyuka okukhulu kwiindleko zokugcina kamva.
