Abantu abaninzi basenokuba baye baba nala mava: Nangona iifestile zivaliwe, imvula isangena emakhayeni yaye umlozi weenqwelo-mafutha kwindlela esezantsi uvakala kakuhle ekhaya.Oku kunokwenzeka ukuba kukungaphumeleli komnyango kunye nefestile ye-sealant!
Nangonai-silicone sealantyinto encedisayo kuphela kwinkqubo yokuvelisa iifestile, ukubala inxalenye encinci yeendleko, idlala indima ebaluleke kakhulu ekusebenzeni kweefestile, ngokukodwa ekungeneni kwamanzi, ukungena komoya, ukugquma kwe-thermal, ukugquma isandi, njl. kujongelwa phantsi.Ukuba i-silicone sealant ineengxaki ezisemgangathweni, iya kubangela iingxaki ezifana nokuvuza kwamanzi kunye nokuvuza komoya, okuya kuchaphazela kakhulu ukuqina komoya kunye nokuqina kwamanzi kwiingcango kunye neefestile.
Ke uluphi uhlobo lwe-silicone oyisebenzisayo kwiifestile?
1. Khetha ngokuchanekileyo iimveliso ezihlangabezana nemigangatho
Kwinkqubo yokukhetha i-silicone sealant, ngaphezu kwemigangatho edibana nayo, ingqalelo kufuneka ihlawulwe kwinqanaba elihambelanayo lokufuduka.Umthamo wokufuduswa sesona salathisi sibaluleke kakhulu ukulinganisa ukuqina kwe-sealant.Okukhona uphezulu umthamo wokufuduswa, kokukhona ukuqina kwe-sealant.Ukucutshungulwa kunye nokufakwa kweefestile, iimveliso ezinomthamo wokufuduka ongekho ngaphantsi kwe-12.5 kufuneka zikhethwe ukuze kuqinisekiswe ukunyanzeliswa komoya ixesha elide kunye nokuqina kwamanzi kwiifestile.
Ngethuba lofakelo kunye nokusetyenziswa kweefestile, impembelelo yokudibanisa phakathi kwee-sealants eziqhelekileyo kunye ne-samente ikhonkrithi idla ngokuba yimbi ngakumbi kuneeprofayili ze-aluminium okanye iiglasi zeengcango kunye neefestile.Ngoko ke, kufaneleka ngakumbi ukusebenzisa i-sealant esetyenziselwa ukufakwa kwefestile e-China ukuthobela i-JC / T 881.
Iimveliso ezinamazinga aphezulu okufuduka ziyakwazi ukumelana neenguqu kwi-joint displacement.Kunconywa ukuba ukhethe iimveliso ezinamazinga aphezulu okufuduka kangangoko kunokwenzeka.
2. Khetha ngokuchanekileyo iimveliso ze-sealant ngokwesicelo
Iifestile zesakhelo ezifihliweyo kunye neefeni zokuvula isakhelo ezifihlakeleyo zifuna isitywina solwakhiwo ukuze sidlale indima yokudibanisa kulwakhiwo.I-Silicone structural sealant kufuneka isetyenziswe, kwaye ububanzi bayo bokudibanisa kunye nobukhulu kufuneka buhlangabezane neemfuno zoyilo.
Kwinkqubo yokufakela umnyango kunye nefestile, i-sealant esetyenziselwa ukudibanisa kwamatye okanye ukudibanisa ngamatye kwelinye icala kufuneka ibe yi-sealant ekhethekileyo yamatye edibana nomgangatho we-GB / T 23261.
Kwiingcango zomlilo kunye neefestile okanye izakhiwo zangaphandle iingcango kunye neefestile ezifuna ingqibelelo yomlilo, kufanelekile kakhulu ukusebenzisa izitywini zokuvala umlilo.
Kwiindawo zokufaka izicelo ezineemfuno ezikhethekileyo zokumelana nokungunda, njengamakhitshi, amagumbi okuhlambela kunye neendawo ezimnyama nezifumileyo, izitywini ezithintela ukungunda kufuneka zisetyenziswe xa kutywinwa iingcango neefestile.
3. Musa ukukhetha ii-silicone sealants ezizaliswe ngeoli!
Okwangoku, kukho iingcango ezininzi ezizaliswe yioyile kunye neefestile zefestile kwimarike.Ezi mveliso zizaliswe isixa esikhulu seoli yamaminerali kwaye zinokumelana nokuguga okungahambi kakuhle, okuya kubangela iingxaki ezininzi zekhwalithi.
Izitywini ze-silicone ezifakwe ngeoli ye-mineral ziyaziwa kwishishini njenge "i-oil-extended silicone sealants".I-oyile yeminerali yi-alkane petroleum distillate ehluthayo.Ngenxa yokuba isakhiwo sayo se-molecular sahluke kakhulu kwi-silicone, sinokungahambelani kakuhle kunye ne-silicone sealant system, kwaye iya kufuduka kwaye ingene kwi-silicone sealant emva kwexesha elithile.Ngoko ke, "i-sealant ezaliswe ngeoli" ine-elasticity enhle ekuqaleni, kodwa emva kwexesha lokusetyenziswa, i-oyile yamaminerali egcweleyo iyafuduka kwaye ingene kwi-sealant, kwaye i-sealant iyancipha, ilukhuni, iqhekeke, kwaye kukho ingxaki non-bonding.
NdiyathembaSiway'sintshayelelo inokukuzisela uncedo!
