• uphawu - kuba ngesiseko owomileyo;
• a ukufuma - kuba nalamazwe isiseko emanzi nokufika udibane nazo ibingenakunyakama.

Lyu sealant udume kakhulu phakathi abakhi mihla, nabo bonke enkosi eziliqela iimpawu. Le yokugqibela ziquka:

• inertness chemical;
• ukumelana umonakalo kunye neziphumo thermal;
• amathuba bala;
• ukusebenza;
• kwalo.

Mhlawumbi ethile kuphela sealant ngokusekelwe lyu into ngexabiso layo eliphezulu. Kodwa ngokuncama iyahlala ngempumelelo flow oko kufanelekile. Ngaphezu koko, oko kuba sealant uphahla qho lyu kuthathwa ukuba yonke. Kwaye zonke ngenxa adhesion kwayo iindawo ezininzi ezaziwayo: iinkuni, isinyithi, ngezitena, eziphathekayo.

tape sealant

Ukuba ukhangela eziphathekayo, kumnandi ukusebenzisa kwaye ngaxeshanye ngempumelelo ngokwaneleyo, ngokuqinisekileyo uya incasa sealant tape ukuya eluphahleni. Isiseko apha butyl irabha, kukho izinto yokunikwa iipropati ezizodwa kunye neempawu. Tape Sealants elungileyo ukumelana utshintsho lobushushu ezahlukeneyo, kunye elangeni ngqo, oko kuhambisana kahle yophahla. Amakhasethi babe namandla eliphezulu lib, lula umsebenzi wofakelo: kwanele ukusebenzisa imveliso kwindawo izinto uqhagamshelo, cinezela ngokuqinileyo - kwaye ufumana, uqhagamshelwano ethembekileyo ixesha elide, kwaye okubaluleke kakhulu tight.

Ukuqhela yophahla metal

Ukuba ugqiba ekubeni amalungiselelo uphahla eyenziwe ngentsimbi, i sealant ukuba kude kwaso kufuneka adhesion elihle imiphezulu otyhidiweyo, yenza ukungcangcazela, impembelelo ye kwezulu. Le propati zisekelwe itha yokuncamathelisa lyu. Ukuze asebenze nabo kufuneka kuqala obuphantsi degreased sijike eqhelekileyo.

Okubalulekileyo! Kuba kophahla metal abicah ngokucacile ayifanelekile - ikwazi oxidizing intsimbi kwaye ibangele umhlwa ngaphambi kwexesha, nto leyo azamkeleki kule meko.

Le ubushushu uphahla ebhodini incence

Izixhobo kubandakanya oxwesileyo lophahla kunye nitrogen nkqo kwemathiriyeli ezifulelwe. Kulo mzekelo, elungileyo acrylic kufanelekile, abicah kunye lyu sealant. Phambi kokuba umsebenzi kuyimfuneko ukuba degrease isiseko kwaye uqinisekise ukuba njani na kowomileyo - kuphela kulo mzekelo, unako ukubala kubuchule phezulu.

Ukuqhela uphahla soft

Ndidinga sealant kuphandla ezitofotofo na? Emva koko kufuneka uhlale phezu iintlobo, ngokusekelwe apho kukho ngetha. Kuba amalungu caba uphahla yokwambathisa ngcono ukusetyenziswa ngebhitumene yemastic, nangenxa amalungu kubangela - ngetha sealant. Inika inamehlo nkqi, ixesha elide yaye ezikumgangatho ophezulu esitalini ukuya ukuhla ubushushu kwaye zonke ezimbi ibonisa zemozulu.

Tytan - ukuphendula abenzi mihla

sealant kophahla Tytan yi kwasungulwa abenzi mihla zezixhobo zokwakha. Eli candelo enye, iplastiki kunye nokwakhiwa viscous, esekelwe kwindibaniselwano ngebhitumene zerabha. Esi sealant elihle ebonakala adhesion eliphezulu ukuya intsimbi kunye substrates bituminous.

Umsebenzi kufuneka balumke, kulumkele ungayibaxi kunye nezinto ethambileyo ukululekwa. Emva kokugqitywa komsebenzi kuyimfuneko ukuqinisekisa ukuba ubume ibambelela isiseko kunye kungqameko uphahla - isiqinisekiso yokudityaniswa ethembekileyo tight.

High-umgangatho ubushushu kophahla - isitshixo iyahlala kwaye nokuthembeka. Kungenxa yoko le nto kubaluleke kangaka ukwenza uhlolo rhoqo uphahla, kuhlaziywe seams ezivulekileyo, uqhekeke ndakubumba. Kwaye kuphela ngezinto ezikumgangatho ophezulu kufuneka isetyenziselwe le njongo. Kwaye akukho mfuneko yokubhenela Ngoncedo iingcali - kunye uninzi umsebenzi yaphathwa ngokuzimeleyo.
