Thaum nws los txog rau cov tshuaj sealant thiab cov nplaum, ob lo lus uas feem ntau tsis meej pem - RTV thiab silicone. Puas yog lawv zoo ib yam lossis puas muaj qhov sib txawv tseem ceeb? Yuav kom txiav txim siab tau zoo txog kev xaiv cov khoom zoo rau koj cov kev xav tau tshwj xeeb, cia peb piav qhia txog lub ntiaj teb paub tsis meej ntawm RTV thiab silicone.
Cov lus txhais ntawm RTV thiab Silicone:
RTV, lossis chav sov vulcanization, hais txog cov sealant lossis nplaum uas kho tau ntawm chav sov yam tsis tas yuav kub.Cov silicones, ntawm qhov tod tes, yog cov polymers tsim los ntawm silicon, oxygen, hydrogen, thiab carbon atoms. Vim nws muaj ntau yam khoom siv, nws yog siv dav ua cov sealant lossis nplaum.
Cov Tshuaj Muaj pes tsawg leeg:
Thaum ob leegRTV thiab siliconeyog cov sealant, lawv muaj cov tshuaj sib txawv. RTVs feem ntau muaj cov polymer puag ua ke nrog cov fillers, cov neeg sawv cev curing thiab lwm yam additives. Cov polymers puag yuav txawv thiab suav nrog cov ntaub ntawv xws li polyurethane, polysulfide lossis acrylic.
Ntawm qhov tod tes, silicone yog ib yam khoom uas tau los ntawm silicon. Nws feem ntau sib xyaw nrog lwm cov tshuaj xws li oxygen, carbon thiab hydrogen, ua rau muaj cov khoom siv hloov pauv tau yooj yim thiab ruaj khov. Kev sib xyaw ua ke ntawm cov ntsiab lus no tso cai rau silicones kom tswj tau lawv cov khoom nyob rau hauv ntau yam xwm txheej ib puag ncig.
Cov yam ntxwv thiab daim ntawv thov:
Ib qho ntawm qhov sib txawv tseem ceeb ntawm RTVs thiab silicones yog lawv cov khoom thiab daim ntawv thov.
1. RTV:
- Muaj kev tiv taus zoo rau cov tshuaj lom neeg, roj thiab roj av.
- Muab lub zog tensile siab thiab yooj ywm.
- Feem ntau siv rau hauv kev lag luam xws li tsheb, kev tsim kho thiab kev tsim khoom.
- Zoo heev rau kev kaw cov seams, sau cov qhov sib txawv thiab txuas cov substrates.
2. Silica gel:
- Tiv taus kub heev, UV rays, av noo thiab huab cua.
- Cov khoom siv hluav taws xob zoo heev.
- Nrhiav cov ntawv thov hauv cov teb xws li kev lag luam hluav taws xob, kev kho mob thiab kev lag luam aerospace.
- Rau kev sib khi, kev cog qoob loo, gasketing thiab kev sib txuas qhov twg yuav tsum tau ua kom tsis txhob muaj kev kub ntxhov.
Cov txheej txheem kho:
Lwm qhov sib txawv tseem ceeb ntawm RTV thiab silicone yog lawv cov txheej txheem kho.
1. RTV:
- Yuav tsum muaj av noo hauv huab cua lossis qhov chaw sib cuag nrog qhov chaw kom pib ua kom cov txheej txheem kho.
- Lub sijhawm kho sai, feem ntau tsis pub dhau 24 teev.
- Tej zaum yuav xav tau ib daim primer kom lo rau qee cov ntaub ntawv.
2. Silica gel:
- Kho los ntawm cov dej noo hauv huab cua lossis los ntawm kev siv cov tshuaj catalyst.
- Lub sijhawm kho ntev dua, xws li ob peb teev mus rau ob peb hnub, nyob ntawm seb muaj dab tsi xws li qhov kub thiab txias thiab av noo.
- Feem ntau nws nplaum rau ntawm feem ntau ntawm cov nto yam tsis tas yuav siv cov primer.
Kev xav txog tus nqi:
Thaum xaiv RTV thiab silicone, tus nqi feem ntau yog qhov tseem ceeb.
1. RTV:
- Feem ntau pheej yig dua li silicone.
- Muaj kev ua tau zoo hauv nws cov nqi.
2. Silica gel:
- Vim nws cov yam ntxwv zoo tshaj plaws thiab kev ua tau zoo, tus nqi siab dua me ntsis.
- Zoo rau cov ntawv thov uas xav tau kev tiv taus rau cov xwm txheej hnyav.
Hauv kev xaus lus, txawm hais tias RTV thiab silicone muaj qee yam zoo sib xws li cov sealant, lawv qhov sib txawv yog nyob rau hauv cov tshuaj lom neeg muaj pes tsawg leeg, kev ua tau zoo, kev siv, txheej txheem kho thiab tus nqi. Kev nkag siab txog cov nuances no yog qhov tseem ceeb rau kev xaiv cov khoom kom raug rau koj cov kev xav tau tshwj xeeb. Txawm hais tias koj xaiv RTV rau nws qhov ruaj khov lossis silicone rau nws qhov ruaj khov, kev txiav txim siab paub zoo yuav pab koj ua tiav koj cov txiaj ntsig xav tau.
