Uma kukhulunywa ngama-sealant nama-adhesives, amagama amabili ajwayelekile avame ukudideka - i-RTV ne-silicone.Ingabe ziyefana noma kukhona umehluko ophawulekayo?Ukuze wenze isinqumo esinolwazi mayelana nokukhetha umkhiqizo ofanele izidingo zakho ezithile, ake sihlukanise umhlaba ongaqondakali we-RTV ne-silicone.
Izincazelo ze-RTV ne-Silicone:
I-RTV, noma i-vulcanization yezinga lokushisa legumbi, isho into evalekayo noma into enamathelayo elapha ekamelweni ngaphandle kwesidingo sokushisa.Ngakolunye uhlangothi, ama-silicones angama-polymers okwenziwa akhiwe i-silicon, umoya-mpilo, i-hydrogen, nama-athomu e-carbon.Ngenxa yezakhiwo zayo eziningi, isetshenziswa kabanzi njenge-sealant noma i-adhesive.
Ukwakhiwa Kwekhemikhali:
Nakuba kokubili i-RTV ne-silicone zingama-sealant, zinezinhlobo ezahlukene zamakhemikhali.Ama-RTV ngokuvamile ahlanganisa i-polymer eyisisekelo ehlanganiswe nama-filler, ama-ejenti okwelapha nezinye izithasiselo.Ama-polymers ayisisekelo angahluka futhi afake izinto ezifana ne-polyurethane, i-polysulfide noma i-acrylic.
I-silicone, ngakolunye uhlangothi, iyinto etholakala ku-silicon.Ivamise ukuxutshwa nezinye izinhlanganisela ezifana ne-oxygen, i-carbon ne-hydrogen, okuholela kumkhiqizo wokugcina oguquguqukayo futhi ohlala njalo.Inhlanganisela eyingqayizivele yalezi zakhi ivumela ama-silicone ukuthi agcine izakhiwo zawo ngaphansi kwezimo eziningi zemvelo.
Izici nezinhlelo zokusebenza:
Omunye umehluko oyinhloko phakathi kwama-RTV nama-silicone izakhiwo zawo kanye nezicelo.
1. I-RTV:
- Iyakwazi ukumelana namakhemikhali, amafutha kanye namafutha.
- Inikeza amandla okuqina aphezulu nokuvumelana nezimo.
- Isetshenziswa kakhulu ezimbonini ezifana nezezimoto, ezokwakha nezokukhiqiza.
- Kuhle kakhulu ekuvaleni ama-seams, ukugcwalisa izikhala kanye nama-bonding substrates.
2. Ijeli yesilika:
- Imelana kakhulu nokushisa okudlulele, imisebe ye-UV, umswakama kanye nesimo sezulu.
- Excellent kagesi ukwahlukanisa izakhiwo.
- Thola izinhlelo zokusebenza emikhakheni efana ne-electronics, imboni yezokwelapha kanye ne-aerospace.
- Ukubeka uphawu, ukubumba, ukudonsa umoya kanye nokubopha lapho kudingeka ukumelana nezimo ezimbi kakhulu.
Inqubo yokwelapha:
Omunye umehluko obalulekile phakathi kwe-RTV ne-silicone inqubo yabo yokwelapha.
1. I-RTV:
- Umswakama womkhathi noma ukuthintana kwendawo kuyadingeka ukuze kuqalwe inqubo yokwelapha.
- Isikhathi sokwelapha ngokushesha, ngokuvamile phakathi kwamahora angu-24.
- Kungase kudinge i-primer ukunamathela kwezinye izinto.
2. Ijeli yesilika:
- Ukwelapha ngomswakama emoyeni noma ngokusebenzisa i-catalyst.
- Isikhathi sokwelapha side, sisukela emahoreni ambalwa kuya ezinsukwini ezimbalwa, kuye ngezici ezifana nezinga lokushisa nomswakama.
- Inamathela ezindaweni eziningi ngokuvamile ngaphandle kwesidingo se-primer.
Izindleko zokucatshangelwa:
Uma ukhetha phakathi kwe-RTV ne-silicone, izindleko ngokuvamile ziyisici esibalulekile.
1. I-RTV:
- Imvamisa kubiza kakhulu kune-silicone.
- Inikeza ukusebenza okuhle ebangeni layo lentengo.
2. Ijeli yesilika:
- Ngenxa yezici nokusebenza kwayo okuphezulu, intengo iphakeme kancane.
- Ilungele izinhlelo zokusebenza ezidinga ukumelana nezimo ezimbi kakhulu.
Ukufingqa, nakuba i-RTV ne-silicone inokufana okuthile njengama-sealant, umehluko wabo ulele ekwakhekeni kwamakhemikhali, ukusebenza, ukusetshenziswa, inqubo yokwelapha kanye nezindleko.Ukuqonda lawa manuances kubalulekile ekukhetheni umkhiqizo ofanele wezidingo zakho ezithile zephrojekthi.Kungakhathaliseki ukuthi ukhetha i-RTV ngenxa yokuqina kwayo noma i-silicone ngenxa yokuqina kwayo, ukwenza isinqumo esinolwazi kuzokusiza uzuze ngempumelelo imiphumela oyifunayo.
