Uma kukhulunywa ngama-sealant nama-adhesive, amagama amabili avamile avame ukudideka - i-RTV ne-silicone. Ingabe ziyafana noma kukhona umehluko ophawulekayo? Ukuze senze isinqumo esinolwazi mayelana nokukhetha umkhiqizo ofanele izidingo zakho ezithile, ake sichaze umhlaba oyimfihlakalo we-RTV ne-silicone.
Izincazelo ze-RTV ne-Silicone:
I-RTV, noma i-vulcanization yokushisa kwegumbi, ibhekisela kusivikelo noma inhlaka ephola ekushiseni kwegumbi ngaphandle kwesidingo sokushisa.Ama-SiliconeNgakolunye uhlangothi, ama-polymer okwenziwa akhiwe ngama-athomu e-silicon, i-oxygen, i-hydrogen, kanye ne-carbon. Ngenxa yezakhiwo zayo eziningi zokusebenza, isetshenziswa kabanzi njenge-sealant noma i-glue.
Ukwakheka Kwamakhemikhali:
Ngesikhathi bobabiliI-RTV ne-siliconeziyizinto zokuvala, zinezinhlobo ezahlukene zamakhemikhali. Ama-RTV ngokuvamile aqukethe i-polymer eyisisekelo ehlanganiswe nama-filler, ama-curing agents kanye nezinye izithasiselo. Ama-polymer ayisisekelo angahluka futhi afaka izinto ezifana ne-polyurethane, i-polysulfide noma i-acrylic.
Ngakolunye uhlangothi, i-silicone iyinto etholakala ku-silicon. Ivame ukuhlanganiswa nezinye izinto ezifana nomoya-mpilo, ikhabhoni kanye ne-hydrogen, okuholela kumkhiqizo wokugcina oguquguqukayo nohlala isikhathi eside. Inhlanganisela eyingqayizivele yalezi zinto ivumela ama-silicone ukuthi agcine izakhiwo zawo ngaphansi kwezimo eziningi zemvelo.
Izici kanye nezinhlelo zokusebenza:
Omunye umehluko omkhulu phakathi kwama-RTV nama-silicone yizakhiwo zawo kanye nokusetshenziswa kwawo.
1. I-RTV:
- Inokumelana okuhle namakhemikhali, uwoyela kanye namafutha.
- Inikeza amandla aphezulu okuthambekela kanye nokuguquguquka.
- Ivame ukusetshenziswa ezimbonini ezifana nezimoto, ezokwakha kanye nezokukhiqiza.
- Kuhle kakhulu ekuvaleni imithungo, ukugcwalisa izikhala kanye nezindawo zokubopha.
2. Ijeli ye-Silica:
- Imelana kakhulu nokushisa okukhulu, imisebe ye-UV, umswakama kanye nesimo sezulu esibi.
- Izakhiwo ezinhle kakhulu zokuvikela ugesi.
- Thola izinhlelo zokusebenza emikhakheni efana nezimboni ze-elekthronikhi, zezokwelapha nezezindiza.
- Ukuvala, ukufaka izimbiza, ukufaka i-gasket kanye nokubopha lapho kudingeka khona ukumelana nezimo ezimbi kakhulu.
Inqubo yokwelapha:
Omunye umehluko obalulekile phakathi kwe-RTV ne-silicone inqubo yazo yokulungisa.
1. I-RTV:
- Umswakama womoya noma ukuthintana komhlaba kuyadingeka ukuze kuqalwe inqubo yokupholisa.
- Isikhathi sokuphulukiswa okusheshayo, ngokuvamile zingakapheli amahora angu-24.
- Kungadinga i-primer ukuze inamathele kwezinye izinto.
2. Ijeli ye-Silica:
- Ukwelapha ngomswakama emoyeni noma ngokusebenzisa i-catalyst.
- Isikhathi sokupholisa sithatha isikhathi eside, kusukela emahoreni ambalwa kuya ezinsukwini eziningana, kuye ngezici ezifana nokushisa nomswakama.
- Inamathela ezindaweni eziningi ngokuvamile ngaphandle kwesidingo se-primer.
Izindleko okufanele uzicabangele:
Uma ukhetha phakathi kwe-RTV ne-silicone, izindleko zivame ukuba yisici esibalulekile.
1. I-RTV:
- Ngokuvamile kubiza kakhulu kune-silicone.
- Inikeza ukusebenza okuhle ngentengo yayo.
2. Ijeli ye-Silica:
- Ngenxa yezici zayo ezinhle kakhulu kanye nokusebenza kwayo, intengo iphakeme kancane.
- Ilungele ukusetshenziswa okudinga ukumelana nezimo ezimbi kakhulu.
Ngamafuphi, yize i-RTV ne-silicone zifana ngandlela thile njenge-sealant, umehluko wazo usekwakhekeni kwamakhemikhali, ukusebenza, ukusetshenziswa, inqubo yokwelapha kanye nezindleko. Ukuqonda la ma-nuances kubalulekile ekukhetheni umkhiqizo ofanele izidingo zakho ezithile zephrojekthi. Kungakhathaliseki ukuthi ukhetha i-RTV ngenxa yokuqina kwayo noma i-silicone ngenxa yokuqina kwayo, ukwenza isinqumo esinolwazi kuzokusiza ukuthi ufeze imiphumela oyifunayo ngempumelelo.
