Xa kufikwa kwiisealants kunye nezincamathelisi, amagama amabini aqhelekileyo adla ngokudida - i-RTV kunye ne-silicone. Ngaba ziyafana okanye kukho umahluko obonakalayo? Ukuze senze isigqibo esinolwazi malunga nokukhetha imveliso efanelekileyo kwiimfuno zakho ezithile, makhe sichaze ihlabathi eliyimfihlakalo le-RTV kunye ne-silicone.
Iinkcazo ze-RTV kunye neSilicone:
I-RTV, okanye i-vulcanization yobushushu begumbi, ibhekisa kwi-sealant okanye i-adhesive ephilisayo kubushushu begumbi ngaphandle kwesidingo sobushushu.IisiliconeKwelinye icala, ziipolymers ezenziwe ngokwenziwa ezenziwe ngeeathom zesilicon, ioksijini, ihydrogen, kunye nekhabhoni. Ngenxa yeempawu zayo ezininzi zokusebenza, isetyenziswa kakhulu njengesitywini okanye isincamathelisi.
Ukwenziwa kweekhemikhali:
Ngelixa bobabiniI-RTV kunye ne-siliconezii-sealants, zinemixube eyahlukeneyo yeekhemikhali. Ii-RTV zihlala zine-polymer esisiseko edityaniswe nezizalisi, ii-curing agents kunye nezinye izongezo. Ii-polymers ezisisiseko zinokuhluka kwaye ziquka izinto ezifana ne-polyurethane, i-polysulfide okanye i-acrylic.
Kwelinye icala, i-silicone yinto ephuma kwi-silicon. Idla ngokuxutywa nezinye izinto ezifana ne-oxygen, i-carbon kunye ne-hydrogen, nto leyo ebangela ukuba imveliso iguquguquke kwaye ihlale ixesha elide. Indibaniselwano eyahlukileyo yezi zinto ivumela ii-silicone ukuba zigcine iimpawu zazo phantsi kweemeko ezahlukeneyo zendalo.
Iimpawu kunye nezicelo:
Omnye wemiba ephambili phakathi kwee-RTV kunye nee-silicone ziimpawu zazo kunye nokusetyenziswa kwazo.
1. I-RTV:
- Inokumelana kakuhle neekhemikhali, iioyile kunye namafutha.
- Inika amandla aphezulu okutsalwa kunye nokuguquguquka.
- Isetyenziswa kakhulu kumashishini afana neemoto, ulwakhiwo kunye nokuvelisa.
- Ilungele ukuvala imithungo, ukuvala izikhewu kunye ne-bonding substrates.
2. Ijeli yeSilica:
- Imelana kakhulu nobushushu obugqithisileyo, imisebe ye-UV, ukufuma kunye nemozulu embi.
- Iipropati ezibalaseleyo zokukhusela umbane.
- Fumana usetyenziso kwiinkalo ezifana ne-elektroniki, ezonyango kunye namashishini eenqwelo moya.
- Ukuvala, ukufaka izimbiza, ukufaka igesi kunye nokubopha apho kufuneka ukumelana neemeko ezinzima.
Inkqubo yokunyanga:
Omnye umahluko obalulekileyo phakathi kwe-RTV kunye ne-silicone yinkqubo yazo yokunyanga.
1. I-RTV:
- Ukufuma komoya okanye ukudibana nomphezulu kuyafuneka ukuze kuqaliswe inkqubo yokunyanga.
- Ixesha lokuphola ngokukhawuleza, ngesiqhelo zingakapheli iiyure ezingama-24.
- Kusenokufuneka i-primer ukuze inamathele kwezinye izinto.
2. Ijeli yeSilica:
- Ukunyanga ngokufuma emoyeni okanye ngokusebenzisa i-catalyst.
- Ixesha lokuphola lide, ukusuka kwiiyure ezimbalwa ukuya kwiintsuku ezininzi, kuxhomekeke kwiimeko ezifana nobushushu kunye nokufuma.
- Inamathela kwiindawo ezininzi ngaphandle kwesidingo seprimer.
Izinto eziqwalaselwayo ngeendleko:
Xa ukhetha phakathi kwe-RTV kunye ne-silicone, ixabiso lidla ngokuba yinto ephambili.
1. I-RTV:
- Ihlala ibiza kakhulu kune-silicone.
- Inika ukusebenza okuhle kuluhlu lwamaxabiso ayo.
2. Ijeli yeSilica:
- Ngenxa yeempawu zayo ezibalaseleyo kunye nokusebenza kwayo, ixabiso liphezulu kancinci.
- Ilungele ukusetyenziswa okufuna ukumelana neemeko ezinzima.
Ngamafutshane, nangona i-RTV kunye ne-silicone zifana kakhulu njenge-sealants, umahluko wazo uxhomekeke kulwakhiwo lweekhemikhali, ukusebenza, ukusetyenziswa, inkqubo yokunyanga kunye neendleko. Ukuqonda ezi mpawu kubalulekile ekukhetheni imveliso efanelekileyo kwiimfuno zakho zeprojekthi. Nokuba ukhetha i-RTV ngenxa yokuqina kwayo okanye i-silicone ngenxa yokuqina kwayo, ukwenza isigqibo esinolwazi kuya kukunceda ufezekise iziphumo ozifunayo ngempumelelo.
