1. Ukucotha kancinci
Ingxaki yokuqala ebangelwa kukuhla ngesiquphe kobushushu obuphakathiisitywina sesakhiwo sesiliconekukuba ivakala ngathi ipholile ngexesha lokufaka, kwaye isakhiwo se-silicone sixinene.
Inkqubo yokunyanga i-silicone sealant yinkqubo yokusabela kweekhemikhali, kwaye ubushushu kunye nokufuma kwendalo kunempembelelo ethile kwisantya sayo sokunyanga. Kwicandelo elinyeizitywino zesakhiwo sesilicone, xa ubushushu kunye nokufuma kuphezulu, kokukhona isantya sokucocwa siya kukhawuleza. Emva kobusika, ubushushu buyehla kakhulu, kwaye kwangaxeshanye, xa kufuma kuphantsi, impendulo yokucocwa kwe-structural sealant iyachaphazeleka, ngoko ke ukucocwa kwe-structural sealant kuyacotha. Phantsi kweemeko eziqhelekileyo, xa ubushushu buphantsi kwe-15 ℃, imeko yokucocwa kancinci kwe-structural sealant iyabonakala ngakumbi.
Isisombululo: Ukuba umsebenzisi ufuna ukwakha kwindawo enobushushu obuphantsi, kucetyiswa ukuba enze uvavanyo lwe-silicone sealant kwindawo encinci ngaphambi kokuba ayisebenzise, kwaye enze uvavanyo lokunamathela kwexolo ukuqinisekisa ukuba i-structural sealant inokunyangeka, ukuba i-adhesion ilungile, kwaye inkangeleko yayo ayiyongxaki. Nangona kunjalo, xa ubushushu obuphakathi buphantsi njenge-4°C, ukwakhiwa kwe-structural sealant akukhuthazwa.
Isitywini sinamatheliswa kusetyenziswa ubushushu kunye nokufuma kwendalo.
2. Iingxaki zokubopha
Ngenxa yokwehla kobushushu kunye nokufuma kunye nokucotha kokuqina, kukwakho nengxaki yokubopha phakathi kwe-structural sealant kunye ne-substrate. Iimfuneko eziqhelekileyo zokusetyenziswa kweisitywina sesakhiwo sesiliconeiimveliso zezi: indawo ecocekileyo enobushushu obuphakathi kwe-10°C ukuya kwi-40°C kunye nokufuma okulinganiselweyo kwe-40% ukuya kwi-80%. Ukudlula kwiimfuno zobushushu ezisezantsi ezingentla, isantya sokubopha siyancitshiswa, kwaye ixesha lokubopha ngokupheleleyo kwi-substrate liyandiswa. Kwangaxeshanye, xa ubushushu buphantsi kakhulu, ukumanzi kwe-glue kunye nomphezulu we-substrate kuncipha, kwaye kusenokubakho inkungu okanye iqabaka engaziwayo kumphezulu we-substrate, echaphazela ukunamathelana phakathi kwe-structural sealant kunye ne-substrate.
Isisombululo: Xa ubushushu obuncinci bokwakha be-structural sealant buyi-10 °C, i-structural sealant ibotshelelwa kwi-substrate kwimeko yokwenyani. Uvavanyo lokuncamathela kufuneka lwenziwe kwindawo yokwakha enobushushu obuphantsi ukuqinisekisa ukunamathela okuhle ngaphambi kokwakha. Ukufakwa kwe-structural sealant efektri kunokukhawulezisa ukuqiniswa kwe-structural sealant ngokunyusa ubushushu kunye nokufuma kwendawo esetyenziswa kuyo i-structural sealant, kwaye kwangaxeshanye, kuyimfuneko ukwandisa ixesha lokuqiniswa ngokufanelekileyo.
3. Yandisa uburhabaxa
Izinto zokuvala izakhiwoiya kuqina kancinci kancinci ize inciphe njengoko ubushushu busiya buncipha. Kwizitywini zesakhiwo ezinamacandelo amabini, izitywini zesakhiwo ezonyusa i-viscosity ziya kwandisa uxinzelelo lomatshini weglue kwaye zinciphise ukuphuma kwe-structural sealant. Kwizitywini zesakhiwo ezinamacandelo elinye, i-structural sealant iyaqina, uxinzelelo oluphezulu lwe-glue gun yokukhupha i-structural sealant lunokuthatha ixesha kwaye lunzima kwimisebenzi yesandla.
Isisombululo: Ukuba akukho mpembelelo ekusebenzeni kakuhle kolwakhiwo, ukuqina kobushushu obuphantsi yinto eqhelekileyo, kwaye akukho manyathelo okuphucula afunekayo.
Ukuba isiphumo sokwakha siyasebenza, kunokwenzeka ukuba ucinge ngokunyusa ubushushu bokusebenza kwe-structural sealant okanye usebenzise amanyathelo okuncedisa ukufudumeza, njengokugcina i-structural sealant kwigumbi lokufudumeza okanye kwigumbi elinomoya opholileyo kwangaphambili, ukufaka i-heater yokufudumeza kwindawo yokusebenzela yokuncamathisela, kunye nokwandisa i-
