Ukuba i-silicone sealant ineengxaki ezisemgangathweni, iya kubangela ukuvuza kwamanzi, ukuvuza komoya kunye nezinye iingxaki, eziya kuchaphazela kakhulu ukuqina komoya kunye nokuqina kwamanzi kwiingcango kunye neefestile.
Ukuqhekeka kunye nokuvuza kwamanzi okubangelwa ukungaphumeleli kocango kunye nefestile ye-sealant
Ngoko sikhetha njani i-sealant efanelekileyo yeengcango kunye neefestile?
1. Khetha ngokuchanekileyo iimveliso ezihlangabezana nemigangatho
Ngexesha lokukhethwa kwe-sealant, ingqalelo kufuneka ihlawulwe kungekuphela nje kumgangatho odibana nayo, kodwa nakwinqanaba elihambelanayo lokufuduswa.Umthamo wokufuduswa sesona salathisi sibaluleke kakhulu ukulinganisa ukuqina kwe-sealant.Ukuphakama komthamo wokufuduka, kokukhona ukuqina kwe-silicone sealant.Ukucutshungulwa kunye nokufakwa kweengcango kunye neefestile kufuneka zikhethe iimveliso ezinomthamo wokufuduka ongekho ngaphantsi kwe-12.5 ukuqinisekisa ukuqina kwexesha elide lomoya kunye nokuqina kwamanzi kwiingcango kunye neefestile.
Ngexesha lofakelo kunye nokusetyenziswa kweengcango kunye neefestile, umphumo wokudibanisa phakathi kwe-sealant eqhelekileyo kunye nekhonkrithi yesamente idla ngokuba yimbi ngakumbi kuneeprofayili ze-aluminium okanye iiglasi zeengcango kunye neefestile.Ngoko ke, kulungele ngakumbi ukukhetha iimveliso ezihambelana ne-JC / T 881 njenge-sealant yokufakwa kweengcango kunye neefestile.
Iimveliso ezinomgangatho ophezulu wokufuduka zinamandla amakhulu okumelana nokutshintsha ngokudibeneyo.Kucetyiswa ukuba ukhethe iimveliso ezinomgangatho ophezulu wokufuduka kangangoko kunokwenzeka.
2. Khethaabicahiimveliso ze-sealant ngokuchanekileyo ngokwenjongo
Iifestile zefreyimu efihliweyo kunye neefenisi zokuvula isakhelo ezifihliweyo zidinga isitywina solwakhiwo ukuze sidlale indima yokudibanisa kwesakhiwo.I-Silicone structural sealant kufuneka isetyenziswe, kwaye ububanzi bayo bokudibanisa kunye nobukhulu kufuneka buhlangabezane neemfuno zoyilo.
Ngethuba lokufakela iingcango kunye neefestile, i-sealant yamatye adibeneyo okanye adibeneyo ngamatye kwelinye icala iya kuba yi-sealant ekhethekileyo yamatye edibana nomgangatho we-GB / T 23261.
I-fireproof sealant ifaneleke ngakumbi kwiingcango kunye neefestile okanye iingcango zangaphandle kunye neefestile zezakhiwo ezifuna ingqibelelo yomlilo.
Kwiindawo zokufaka izicelo ezineemfuno ezikhethekileyo zokuthintela ukungunda, njengeekhikhini, iibhafu zococeko kunye neendawo ezimnyama nezimanzi, ukutywinwa kocango kunye neefestile ezidibeneyo kufuneka kusetyenziswe i-mold proof sealant.
3. Musa ukukhetha i-silicone sealant ezaliswe ngeoli!
Okwangoku, imarike igcwele inani elikhulu leoli egcwele umnyango kunye neefestile zefestile, ezizaliswe ngexabiso elikhulu leoli yamaminerali kwaye inokumelana nokuguga okungahambi kakuhle, okuya kubangela iingxaki ezininzi zekhwalithi.
I-Silicone sealant exutywe neoyile yamaminerali ibizwa ngokuba "yi-oyile egcwele i-silicone sealant" kwishishini.I-oyile yeminerali yeye-saturated alkane petroleum distillation.Ngenxa yokuba isakhiwo sayo se-molecular sahluke kakhulu kwi-silicone, ukuhambelana kwayo kunye ne-silicone sealant system ayilunganga, kwaye iya kufuduka kwaye ingene ngaphandle kwe-silicone sealant emva kwexesha elithile.Ke ngoko, "i-oyile egcwele i-sealant" ine-elasticity entle ekuqaleni, kodwa emva kokusetyenziswa ixesha elithile, i-oyile yeminerali egcweleyo iyafuduka kwaye ingene kwi-sealant, kwaye i-sealant iya kuncipha, iqine, iqhekeke, kwaye ide ibe nengxaki non bonding.
Uninzi lwee-silicone sealants eziphantsi kwexabiso eliphantsi kwimarike zizaliswe ngeoli yezimbiwa, kwaye umxholo we-silicone ye-polymer esisiseko ungaphantsi kwama-50%, kwaye ezinye zingaphantsi kwama-20%.
Ukuba i-sealant yefestile yokuzalisa igesi idibanisa neglasi ye-insulating, i-oyile ye-mineral egcweleyo iya kufuduka kwaye ingene kwiglasi ye-insulating, ibangele ukuchithwa kwe-rubber ye-butyl yokutywinwa kweglasi yokukhusela kunye nokuhamba kweoli.
Khetha iimveliso zokutywina ezikumgangatho ophezulu.Nangona ixabiso le-sealant elithengiweyo kwinqanaba lokuqala liphezulu kancinci, ukusebenza kwayo kunokugcinwa ixesha elide ngaphandle kweengxaki zomgangatho.Khetha ixabiso eliphantsi lexabiso eliphantsi "i-oyile egcwele i-sealant", nangona ixabiso lincinci, ixabiso lokuqala lotyalo-mali liphantsi kancinci;Nangona kunjalo, emva kokwenzeka kweengxaki, iindleko zokulondolozwa kamva, iindleko zemveliso, iindleko zabasebenzi, ilahleko yophawu, njl.njl. ngexesha lokuphinda kuhlaziywe inokuba ngamaxesha amaninzi okanye amatyeli amatyeli exabiso lesitywina ngokwalo;Ayigcinanga nje imali, kodwa yongeza ingxaki enkulu kubasebenzisi.
