Cov tshuaj nplaum silicone yog ib qho ntawm cov khoom siv nplaum thiab cov khoom siv sib khi uas siv tau ntau yam hauv kev tsim kho niaj hnub no. Nws qhov yooj ywm, lub neej ua haujlwm ntev, thiab tiv taus huab cua thiab kub heev ua rau nws yog thawj qhov kev xaiv rau cov kws tshaj lij thoob ntiaj teb.
Txawm li cas los xij, xaiv qhovhom silicone sealant zootsis yooj yim li nws zoo li. Kev xaiv tsis raug tuaj yeem ua rau tsis muaj kev sib txuas, xau, tawg, lossis rov ua dua kim heev. Phau ntawv qhia no muab ib qhokev ua haujlwm theem siab, raws li cov qauv thoob ntiaj teb (ASTM, ISO, GB), los pab koj xaiv cov silicone sealant zoo rau koj qhov project.
1. Sib phim cov tshuaj nplaum rau cov khoom siv hauv pem teb (Cov khoom siv nto)
Cov tshuaj nplaum silicone tsis sib haum nrog txhua yam khoom siv. Kev tsim cov mis tsis raug yuav ua rau xeb lossis tsis sib txuas.
-Iav & Glazing
--Sivneutral kho siliconeCov tshuaj acetoxy (acidic) tuaj yeem ua rau cov hlau sib txuas hauv cov txheej txheem glazing xeb.
--Piv txwv li: Cov phiaj xwm phab ntsa ntaub thaiv xws liChaw Nres Tsheb Ciav Hlau Beijing Southsiv cov silicone kho tsis muaj zog kom ntseeg tau tias muaj 20+ xyoo ntawm kev ruaj khov.
-Aluminium & Hlau Panels
--Cov silicones kho tsis muaj zog raug pom zoo kom tsis txhob oxidation lossis corrosion.
--ASTM C1184 qhia meej txog cov kev cai ua haujlwm rau cov khoom siv foob iav.
-Cov Pob Zeb, Pob Zeb, & Cov Pob Zeb
--Cov khoom siv uas muaj qhov dej ntws yuav tsum tau siv cov tshuaj primers ua ntej siv silicone kom tiv thaiv kev nqus thiab kev nplaum tsis muaj zog.
--Cov silicone nruab nrab uas muaj peev xwm txav tau zoo (± 50%) yog qhov zoo dua rau cov pob qij txha nthuav dav.
-Cov yas (PVC, Polycarbonate, Acrylic)
--Tsis yog txhua cov silicones lo zoo. Kev kuaj xyuas qhov sib xws yog qhov tseem ceeb vim tias qee cov yas tso cov roj uas tiv thaiv kev tawv.
--Hauv cov thawv hluav taws xob, RTV (Chav Kub Vulcanizing) silicones yog ib qho uas pom ntau.
Cov Lus Qhia Zoo:Thov nco ntsoovDaim Ntawv Qhia Txog Kev Siv Tshuab (TDS)los ntawm koj tus neeg muag khoom thiab xyuas cov substrates pom zoo. Rau cov haujlwm loj, ua qhov kev sim sib xws ua ntej thov ntau.
2. Siv sab hauv tsev thiab sab nraum zoov
Cov chaw sib txawv xav tau cov qauv sib txawv heev.
1. Cov Ntawv Siv Sab Hauv Tsev
--Cov khoom siv silicone huv nrogcov tshuaj tiv thaiv kab mob fungalzoo tshaj plaws rau chav ua noj, chav dej, thiab HVAC ducts.
--Lawv tiv thaiv cov pwm dub loj hlob hauv cov cheeb tsam noo noo thiab raug kuaj raws li ISO 846 rau kev tiv thaiv kab mob me me.
--Cov qauv tsim uas muaj VOC tsawg (volatile organic compound) raug pom zoo kom ua tau raws li cov qauv tsev ntsuab niaj hnub (LEED, BREEAM).
2. Cov Ntawv Siv Sab Nraud
--Cov khoom siv foob yuav tsum tiv tausKev cuam tshuam los ntawm UV, ozone, kev hloov pauv ntawm qhov kub thiab txias, thiab kev raug nag.
--Kev kho silicone tsis muaj zog nrog lub peev xwm ntev (txog li 400%) ua kom lub foob tseem nyob ruaj khov hauv qab thermal expansion.
--Piv txwv li:Lub Chaw Haujlwm CCTV hauv BeijingYuav tsum muaj cov tshuaj silicone sealant ua haujlwm siab rau cov pob qij txha ntawm lub ntsej muag uas raug rau -20 ° C lub caij ntuj no thiab + 40 ° C lub caij ntuj sov.
3. Tej Yam Uas Ua Rau Ib Puag Ncig Thiab Kev Nyuaj Siab Ntawm Lub Cev
Ua ntej xaiv cov sealant, soj ntsuam qhovtej yam kev ntxhov siabkoj qhov project yuav ntsib:
1). Kev Tiv Thaiv Kub
--Cov silicones siv dav dav: -40 ° C txog + 150 ° C
--Cov silicones kub siab: txog li + 300 ° C kev raug txuas ntxiv mus
--Piv txwv li: Cov gaskets tsheb siv cov silicone kub liab kom tiv taus cua sov ntawm lub cav.
2). Dej noo thiab av noo
--Chav dej thiab chav ua noj: siv cov silicone huv uas muaj cov tshuaj tiv thaiv pwm.
--Cov choj sab nraum zoov thiab cov qhov av: kev tiv thaiv dej nkag yog qhov tseem ceeb heev.
3). Kev Muaj Peev Xwm Txav Mus Los
--Txhais los ntawm ASTM C719 (kev txav ntawm cov sealant).
--Cov pob qij txha nthuav dav hauv façades: ± 50% kev txav mus los xav tau.
--Cov sealant uas txav mus los tsawg (±12.5%) tsuas yog tsim rau cov qhov me me xwb.
4. Cov Kev Siv Rau Cov Qauv Thiab Cov Uas Tsis Yog Cov Qauv
1). Cov Khoom Siv Silicone Uas Muaj Cov Qauv
--Siv rau hauv cov ntaub thaiv phab ntsa glazing thiab load-bearing bonding.
--Yuav tsum ua raws li ASTM C1184 lossis GB 16776 (Tuam Tshoj).
--Yuav tsum tau npaj qhov chaw kom meej, tsim qhov sib koom ua ke, thiab tswj xyuas kom zoo thaum lub sijhawm teeb tsa.
2). Cov Khoom Siv Silicones Dav Dav
--Tus nqi tsim nyog, yooj yim siv, thiab tsim nyog rau kev kho vaj tse thiab kev kaw tsis tseem ceeb.
--Lub neej feem ntau luv dua (5-10 xyoo) piv rau cov silicones uas muaj cov qauv (20-30 xyoo).
5. Cov Ntawv Pov Thawj thiab Cov Qauv Zoo
Cov neeg yuav khoom tshaj lij yuav tsum xyuas cov ntawv pov thawj tas li:
--ISO 9001 & ISO 14001- Cov txheej txheem tswj xyuas zoo thiab ib puag ncig.
--Cov Qauv ASTM– C920 (elastomeric joint sealants), C1184 (structural glazing).
--GB Cov Qauv (Tuam Tshoj)- GB/T 14683 (cov khoom siv foob hauv tsev).
--Cim CE (Tebchaws Europe)- Ua kom ua raws li cov qauv kev nyab xeeb thiab kev ua haujlwm ntev ntawm European.
Cov ntawv pov thawj no txo cov kev pheej hmoo ntawm cov haujlwm thiab ua kom ntseeg tau tias ua raws li tsoomfwv thiab kev lag luam xav tau.
6. Yooj yim ntawm daim ntawv thov
Ib Cheebtsam (RTV) Silicone
--Cov cartridges los yog sausages uas npaj siv tau.
--Kho tau nrog cov dej noo ib puag ncig, feem ntau hauv 24–48 teev.
--Zoo tagnrho rau cov ntawv thov hauv qhov chaw uas qhov ceev thiab yooj yim tseem ceeb.
Ob-Cheeb Tsam Silicone
--Yuav tsum tau sib tov, tab sis kho sai dua thiab sib xws dua.
-- Nyiam rauHoobkas iavthiabcov kab sib dhos ua lag luam.
--Piv txwv li: Siv rau hauv cov kab tsim khoom siv phab ntsa kom ruaj khov tas li.
7. Tus nqi piv rau kev ua tau zoo ntawm lub neej
Nws yog ib qho kev ntxias kom xaiv cov sealant pheej yig tshaj plaws, tab sis tus nqi tag nrho ntawm lub neej tseem ceeb dua.
--Cov khoom siv foob pheej yig: qis dua qhov lo, xim tsis sib xws, tawg hauv 3-5 xyoos.
--Cov khoom siv silicone zoo tshaj plaws: 20–30 xyoo ntawm lub neej ua haujlwm, tus nqi txij nkawm qis dua, thiab ROI zoo dua mus sij hawm ntev.
--Hauv cov haujlwm loj loj, covTus nqi sealant yog <1% ntawm tag nrho cov peev nyiaj façade, tab sis kev ua tsis tiav ntawm cov sealant tuaj yeem ua rau muaj kev kho ntau lab daus las.
