Ulwazi oluyisisekelo lwama-silicone sealants

1. Ukuhlelwa:

I-Silicone sealant ingahlukaniswa ngezigaba ezimbili kusukela ekufakweni komkhiqizo: ingxenye eyodwa kanye nengxenye emibili. Ukuphulukiswa kwe-silicone sealant ye-single-component kubangelwa izinguquko ezibonakalayo ngenxa yokuxhumana nomswakama emoyeni;

I-silicone sealant enezingxenye ezimbili isho ukuthi ingcina ye-silicone ihlukaniswe ngamaqembu amabili, A no-B. Alikho iqembu elingaqina uma likhona lodwa. Kodwa lapho amasethi amabili eglue exutshwe, ayaqina.

Njengamanje, okuvame kakhulu emakethe yi-single-component silicone sealant.

I-Acid silicone sealant isetshenziselwa ikakhulukazi ukuhlanganisa okuvamile phakathi kwengilazi nezinye izinto zokwakha. Iglue engathathi hlangothi inqoba izici zeglue ene-asidi egqwalisa izinto zensimbi futhi isabela ngezinto ezine-alkaline, ngakho inohlu olubanzi lwezinhlelo zokusebenza futhi intengo yayo yemakethe ingaphezulu kancane kweglue ene-asidi.

Uhlobo olukhethekile lweglue yengilazi emakethe i-silicone structural sealant. Ngenxa yokuthi isetshenziselwa ngokuqondile isakhiwo sensimbi nengilazi noma ukuhlanganiswa okungezona kwesakhiwo kwezindonga zamakhethini engilazi, izidingo zekhwalithi kanye nebanga lomkhiqizo ziphakeme kakhulu phakathi kwamaglue engilazi. Intengo yemakethe nayo iphakeme kakhulu.

2. Injongo

(1) I-Acid silicone sealant (isibonelo Ama-733)

① Ifanele ukuvalwa, ukuvinjwa, ukuvimbela ukuvuza nezinjongo zokuvikela umoya. Ifanele ukusetshenziswa kwangaphakathi nangaphandle (umphumela wangaphakathi ungcono), futhi umphumela wokunqanda ukubola kanye nomphumela wokuvuza wokuvuza uyamangalisa.

② Ukuhlanganiswa kwemihlobiso ehlukahlukene yangaphakathi yezimoto, okuhlanganisa: insimbi, izindwangu nezindwangu zemvelo namapulasitiki.

③ Bandakanya ama-gaskets kumshini wokushisisa nokupholisa.

④ Faka izimbambo ezingenazo izimbobo zesikulufu, ama-nameplates nopende kanye nezinto zepulasitiki endaweni yensimbi.

⑤ Vala amafasitela esicabheni sikahhavini, umtshingo, izihlanganisi zamapayipi, nezicabha zokungena ezintweni zikagesi.

⑥ Nikeza ama-gasket akhiqizwe ngokushesha angavuzi amabhokisi egiya, ama-compressor, namaphampu.

⑦ Vala ikhabethe namafasitela.

⑧ Ukuvalwa kwe-trailer namafasitela ekhebhu yamaloli.

⑨ Izingxenye zempahla yokubopha nokuvala.

⑩ Yakha i-anti-wear coating.

11 Ishidi lensimbi elincanyana elingaphakathi neligcwaliswe ngokweqiniso, inethiwekhi yamapayipi kanye nebhokisi lempahla.

(2) Isivalisi se-silicone esimelana nesimo sezulu esingathathi hlangothi ( Ama-789)

① Ifanele ukuvalwa kokumelana nesimo sezulu kwezindonga zamakhethini ezihlukile, ezinconyelwe ikakhulukazi ukuvalwa kwekhethini ukumelana nesimo sezulu kwezindonga zamakhethini engilazi, izindonga zamakhethini zephaneli ye-aluminium-plastic, kanye nokulengiswa kwamatshe okomile;

② Ukuvalwa komthungo phakathi kwensimbi, ingilazi, i-aluminium, amathayela e-ceramic, ingilazi yemvelo, nengilazi eboshwe;

③ Ukuvala umthungo kukhonkolo, usimende, amatshe, imabula, insimbi, ukhuni, i-aluminiyamu ene-anodized kanye nezindawo ezipendiwe ze-aluminium. Ezimweni eziningi asikho isidingo sokusebenzisa i-primer.

(3) Isinamathiselo sesakhiwo se-silicone (Ama-793)

① Isetshenziswa kakhulu kumadivayisi ahlanganisayo esakhiwo noma angekho esakhiwo phakathi kwensimbi nengilazi yezindonga zamakhethini engilazi.

② Ingakwazi ukuxhuma ngokuqondile ingilazi ebusweni bezingxenye zensimbi ukuze yakhe ingxenye yomhlangano eyodwa, ehlangabezana nezidingo zokuklanywa kwezindonga zamakhethini ezinamafreyimu agcwele noma afihleke kancane.

③ Ukuhlanganiswa kwesakhiwo nokuvalwa kwengilazi yokuvikela.

3. Imikhawulo

Zonke izinhlobo ze-silicone sealant zingaphansi kwemikhawulo elandelayo lapho zisetshenziswa:

① Ayilungele ukwakhiwa ezindaweni ezicwiliswe emanzini isikhathi eside;

② Ayihambisani nezinto ezizovuza amafutha, amapulasitiki noma izincibilikisi;

③ Ngeke isetshenziswe endaweni eqhwaqhwa noma emanzi. Ukunamathela;

④ Ayinakwelashwa endaweni evalwe ngokuphelele (ijeli ye-silica idinga ukuphulukiswa umswakama emoyeni);

⑤ Ingaphezulu le-substrate alihlanzekile noma liqinile.
