1. Ukunyanga okucothayo
Ingxaki yokuqala ukuba ukuhla ngesiquphe kwiqondo lobushushu ambient kuzisa kwii-silicone yesakhiwo sealantkukuba uziva uphilisiwe ngexesha lenkqubo yesicelo, kwaye isakhiwo se-silicone sixinene.
Inkqubo yokuphilisa ye-silicone sealant yinkqubo yokusabela kweekhemikhali, kwaye ubushushu kunye nokufuma kwendalo kunempembelelo ethile kwisantya sokunyanga.Kwicandelo elinyei-silicone yesakhiwo sealants, okukhona ubushushu obuphezulu kunye nokufuma, kokukhona isantya sokunyanga siya kukhawuleza.Emva kobusika, ukushisa kwehla ngokukhawuleza, kwaye ngexesha elifanayo, kunye nomswakama ophantsi, ukuphendulwa kokunyanga kwe-sealant yesakhiwo kuchaphazeleka, ngoko ke ukunyangwa kwe-sealant yesakhiwo kuhamba kancane.Phantsi kweemeko eziqhelekileyo, xa iqondo lobushushu lingaphantsi kwe-15 ℃, isenzeko sokucotha ukunyangeka kwesitywina sesakhiwo sibonakala ngakumbi.
Isisombululo: Ukuba umsebenzisi ufuna ukwakha kwindawo yokushisa ephantsi, kuyacetyiswa ukuba aqhube uvavanyo lwe-silicone sealant encinci ngaphambi kokusetyenziswa, kwaye uqhube uvavanyo lwe-adhesion ye-peel ukuqinisekisa ukuba i-sealant yesakhiwo inokunyangwa, ukubambelela kulungile, kwaye ukubonakala akuyongxaki.indawo esetyenziswayo.Nangona kunjalo, xa ubushushu be-ambient buphantsi kwe-4 ° C, ukwakhiwa kwe-structural sealant akukhuthazwa.
Isitywina sincamatheliswa kusetyenziswa ubushushu kunye nokufuma kokusingqongileyo.
2. Iingxaki zokudibanisa
Ngokuhla kweqondo lokushisa kunye nokufuma kunye nokunyangwa okucothayo, kukwakho ingxaki yokudibanisa phakathi kwe-sealant yesakhiwo kunye ne-substrate.Iimfuno jikelele zokusetyenziswa kwei-silicone yesakhiwo sealantiimveliso zezi: indawo ecocekileyo enobushushu obuyi-10°C ukuya kuma-40°C kunye nokufuma okumalunga ne-40% ukuya kuma-80%.Ukugqithisa iimfuno ezisezantsi zeqondo lokushisa, isantya sokubambisana siyancipha, kwaye ixesha lokudibanisa ngokupheleleyo kwi-substrate lide.Kwangaxeshanye, xa iqondo lobushushu lisezantsi kakhulu, ukumanzi kokuncamathelisa kunye nomphezulu we-substrate kuncipha, kwaye kunokubakho inkungu engabonakaliyo okanye iqabaka kumphezulu we-substrate, echaphazela ukunamathela phakathi kwe-sealant yesakhiwo kunye ne-sealant. isubstrate.
Isisombululo: Xa ubuncinci beqondo lokushisa lokwakhiwa kwe-sealant yesakhiwo yi-10 °C, i-sealant yesakhiwo ibophelelwe kwi-substrate kwimeko yangempela.Uvavanyo lokuncamathela kufuneka lwenziwe kwindawo yolwakhiwo lobushushu obuphantsi ukuqinisekisa ukubambelela kakuhle phambi kokwakhiwa.Inaliti yefektri yesitywina solwakhiwo sealant inokukhawulezisa ukunyangwa kwe-sealant yolwakhiwo ngokwandisa ubushushu kunye nokufuma kokusingqongileyo apho kusetyenziswa isitywina solwakhiwo, kwaye kwangaxeshanye, kuyafuneka ukwandisa ngokufanelekileyo ixesha lokunyanga.
3. Ukwandisa i-viscosity
Izitywini zesakhiwoiya kutyeba ngokuthe chu kwaye ibe lulwelo oluncinci njengoko ubushushu behla.Kumacandelo amabini okutywinwa kwezakhiwo, izitywini zesakhiwo ezinyusa i-viscosity ziya kwandisa uxinzelelo lomatshini weglue kunye nokunciphisa ukukhutshwa kwe-sealant yesakhiwo.Kwicandelo elilodwa le-sealant yesakhiwo, i-sealant yesakhiwo iyaqina, ukunyanzeliswa kwe-glue gun ukukhupha i-sealant yesakhiwo kunokuthatha ixesha kwaye kube nzima kwimisebenzi yezandla.
Isisombululo: Ukuba akukho mpembelelo ekusebenzeni kakuhle kokwakhiwa, ukunyuswa kweqondo lokushisa eliphantsi yinto eqhelekileyo, kwaye akukho manyathelo okuphucula afunekayo.
Ukuba isiphumo sokwakha, kunokwenzeka ukuba kuqwalaselwe ukwandisa ubushushu bokusebenza kwe-sealant yesakhiwo okanye ukwamkela amanyathelo ancedisayo okufudumeza, njengokugcina i-sealant yesakhiwo kwigumbi lokufudumeza okanye igumbi eline-air-conditioning kwangaphambili, ukufaka isifudumezi sokufudumeza ngaphakathi. iworkshop yokuncamathelisa, kunye nokwandisa
