Njengoko sonke sisazi, izakhiwo zilindeleke ukuba zibe nobomi benkonzo ubuncinane beminyaka engama-50. Ngoko ke, izinto ezisetyenzisiweyo kufuneka zibe nobomi obude benkonzo. I-Silicone sealant isetyenziswe ngokubanzi kwintsimi yokwakhiwa kokungangeni kwamanzi kunye nokutywinwa ngenxa yokumelana kwayo okuphezulu kunye nokuphantsi kobushushu, ukuchasana nokuguga kwemozulu, kunye neempawu ezintle zokubambisana. Nangona kunjalo, emva kwexesha elithile emva kokwakhiwa, ukuchithwa kwe-silicone sealant kuye kwaba ngumcimbi oqhelekileyo, oshiya "imigca" ngokukhawuleza kwizakhiwo.
Kutheni iglue ye-silicone itshintsha umbala emva kokusetyenziswa?
Zininzi izizathu zokutshintsha umbala ngokuyinxenye okanye okupheleleyo kwe-abicah tonela sealant okanye iglu yeglasi, ikakhulu kule miba ilandelayo:
1. Ukungahambelani kwezixhobo zokutywina ezahlukeneyo Izitywini ze-Acidic, i-alcohol-based sealants engathathi hlangothi, kunye ne-neutral oxime-based sealants ayinakusetyenziswa kunye, njengoko inokuchaphazela omnye nomnye kwaye ibangele ukubola. Izitywini zeglasi ezineasidi zinokubangela ukuba izitywini ezisekwe kwi-oxime zijike zibe tyheli, kwaye ukusebenzisa izitywini zeglasi esekwe kwi-oxime engathathi hlangothi kunye ne-alcohol-based sealants kunye kunokubangela ukutyheli.
Iimolekyuli ezikhutshwe ngexesha lokunyangwa kwe-neutral oxime-type sealants, -C = N-OH, inokusabela kunye ne-acids ukwenza amaqela e-amino, axutywe lula yi-oksijini emoyeni ukuze enze izinto ezinemibala, ezikhokelela ekuguqulweni kwe-sealant.
2. Ukuqhagamshelana nerabha kunye nezinye izinto
Izitywini ze-silicone zinokujika zibe tyheli xa zidibana ngokuthe ngqo neendidi ezithile zerabha, njengerabha yendalo, irabha ye-neoprene, kunye nerabha ye-EPDM. Ezi rubber zisetyenziswa ngokubanzi kwiindonga zekhethini kunye neefestile / iingcango njengeerabha zerabha, iigaskets, kunye nezinye izinto. Olu tshintsho lubonakala ngokungalingani, kunye namalungu kuphela anxibelelana ngokuthe ngqo nerabha ejika ibe tyheli ngelixa ezinye iindawo zihlala zingachaphazeleki.
3. Ukutshintsha kombala kwe-sealant nako kunokubangelwa kukolula okugqithisileyo
Esi siganeko sihlala sichazwa ngempazamo kukulahleka kombala we-sealant, enokubangelwa zizinto ezintathu eziqhelekileyo.
1) I-sealant esetyenzisiweyo igqithise amandla ayo okufuduka kwaye i-joint yoluliwe ngokugqithisileyo.
2) Ubunzima be-sealant kwiindawo ezithile buncinci kakhulu, okubangela ukuba utshintsho lombala lugxininiswe kwezo ndawo.
4. Ukutshintsha kombala kwe-sealant nako kunokubangelwa yimiba yokusingqongileyo.
Olu hlobo lwe-discoloration luxhaphake kakhulu kwii-sealants zohlobo lwe-oxime ezingathathi hlangothi, kwaye esona sizathu siphambili sokuguqulwa kombala kubukho bezinto ezine-acidic emoyeni. Kukho imithombo emininzi yezinto ezine-acidic emoyeni, njengokunyanga i-silicone sealant ene-acidic, i-acrylic coatings esetyenziselwa ukwakhiwa, amanqanaba aphezulu e-sulphur dioxide emoyeni ngexesha lasebusika kwimimandla esemantla, ukutshisa inkunkuma yeplastiki, i-asphalt evuthayo, kunye nokunye. Zonke ezi zinto ezineasidi ezisemoyeni zinokubangela ukuba izinto zokutywina zohlobo lwe-oxime zitshintshe umbala.
Indlela yokuphepha ukuguquguquka kwe-silicone sealant?
I-1) Phambi kokwakhiwa, yenza uvavanyo lokuhambelana kwizinto ezinxibelelene nesitywini ukuqinisekisa ukuhambelana phakathi kwezixhobo, okanye ukhethe izixhobo ezihambelanayo, ezinjengokukhetha iimveliso zerabha ye-silicone endaweni yeemveliso zerabha ukunciphisa amathuba okuba tyheli.
2) Ngexesha lokwakha, i-sealant engathathi hlangothi akufanele idibane ne-asidi sealant. Izinto ze-amine eziveliswa kukubola kwe-sealant engathathi hlangothi emva kokudibana ne-asidi iya ku-oxidize emoyeni kwaye ibangele ukuguquka kombala.
3) Gwema ukudibana okanye ukuvezwa kwe-sealant kwiindawo ezinobungozi ezifana ne-acids kunye ne-alkalis.
4) Ukutshintsha kombala kwenzeka ikakhulu kwiimveliso ezinemibala ekhanyayo, emhlophe, kunye neselubala. Ukukhetha izitywini ezimnyama okanye ezimnyama kunokunciphisa umngcipheko wokuguquka kombala.
I-5) Khetha ama-sealants anomgangatho oqinisekisiweyo kunye negama elihle le-brand-JUNBOND.
