Cov qauv vaj tsev niaj hnub no yog txhais los ntawm qhov pom tseeb thiab kev ua tiav ntawm lub tsev. Hauv plawv ntawm "Silicon-Based Era" no ntawm kev tsim kho yog qhovsilicone sealant rau cov qauv, ib yam khoom siv uas tau hloov zuj zus los ntawm cov organic, carbon-based compromises mus rau cov high-performance inorganic systems. Ua ib tug thawj coj hauv kev lag luam txij li xyoo 1984,Cov Tshuaj Sealant Siwaytau pom qhov kev hloov pauv no, tawm tswv yim rau kev ua kom huv ntawm cov tshuaj tiv thaiv kev kub ntxhov niaj hnub no ntawm cov roj av (roj dawb).
Tus Qauv Txuj Ci: Vim Li Cas Silicon Thiaj Tswj Tau Cov Rooj Tog Niaj Hnub
Kev hloov pauv ntawm cov kab ke "carbon-based" biological mus rau "silicon-based" industrial frameworks yog qhov tseeb hauv kev tsim vaj tsev facade. Thaum cov organic polymers vam khom cov carbon-carbon (CC) bonds, cov iav zoo tshaj plaws siv qhov ruaj khov zoo dua ntawm silicon-oxygen (Si-O) bond.
Qhov Zoo ntawm Cov Tshuaj Si-O Bonds
Qhov kev ua siab ntev ntawm ibsilicone sealant rau cov qauvyog qhov tshwm sim ncaj qha los ntawm nws cov qauv molecular. Lub zog $Si-O$ bond siab dua li ntawm cov kev xaiv carbon, ua rau nws tsis raug UV degradation.
| Kev Sib Koom Tes Tshuaj | Lub Zog Sib Koom Tes (kJ / mol) | Kev tiv thaiv UV |
| Si-O | 460.5 | Zoo heev |
| CO | 358.0 | Nruab nrab |
| Si-C | 318.2 | Nruab nrab |
| CC | 304.0 | Qis |
Qhov kev ruaj khov ntawm cov qauv no tso cai rau Siway cov khoom kom tswj tau elasticity thoob plaws qhov kub thiab txias heev, txij li -50 ℃ txog +150 ℃.
Theem I: Lub Caij Nyoog Uas Muaj Carbon Thiab Kev Tsim Kho Vaj Tse (Xyoo 1980)
Keeb kwm ntawm Tuam Tshoj txoj kev lag luam phab ntsa ntaub tau pib xyoo 1984 nrog lub tsev so Beijing Great Wall. Thaum lub sijhawm no, qhov tsis muaj cov nplaum tshwj xeeb tau yuam cov kws kes duab vajtse siv cov khoom siv organic sealants xws li polysulfides lossis acrylics.

* Cov Tshuaj Polysulfide SealantsRaws li cov pob txha caj qaum carbon-sulfur (CS), cov ntaub ntawv no raug kev txom nyem los ntawm kev tawv thiab poob elasticity thaum raug rau UV hluav taws xob.
-
*Kev Txwv ntawm Kev Tsim QauvVim tias cov sealant uas muaj carbon tsis tuaj yeem ris tau cov khoom hnyav ntev, cov tsev raug txwv rau "exposed frame" (stick), qhov twg cov phaj txhuas tau siv tshuab los khi lub iav.
Theem II: Kev Hloov Pauv Silicon thiab Kev Sawv ntawm Siway (xyoo 1990–2000)
Nruab nrab xyoo 1990 tau cim lub "Hnub Nyoog Kub ntawm Silicon Ntshiab." Kev qhia txogcov khoom siv foob pob silicone uas kho tsis muaj teeb meemtso cai rau kev yug los ntawm cov phab ntsa ntaub thaiv "zais cia", qhov twg cov sealant nws tus kheej dais qhov hnyav ntawm lub iav thiab cov cua ntsawj ntshab.
Tsim muaj xyoo 1984,Cov Tshuaj Sealant Siway(Shanghai Siway Building Materials Co., Ltd.) tau tshwm sim los ua ib lub tuam txhab tsim khoom zoo tshaj plaws 3, tsav tsheb tsim kho tshiab hauv qhov chaw no. Peb cov kab tsim khoom siv tshuab tshiab tshaj plaws ua kom muaj qhov tsis zoo rau cov ntawv thov tseem ceeb.

**Siway SV9900Cov nplaum uas muaj ob yam khoom, khov sai, zoo tagnrho rau kev siv rau cov vaj huam sib luag thiab kev tsim kho siab, ua tau raws li qhov yuav tsum tau ua ntawm ASTM C1184.
- **Siway SV8890： ob-yam khoom silicone structural glazing sealant yog neutral cured, high-modulus, tsim tshwj xeeb rau kev sib dhos ntawm cov qauv glazing ntaub phab ntsa, aluminium ntaub phab ntsa, hlau engineering structural seal thiab kev ua tau zoo insulating iav.
Theem III: Qhov Txaus Ntshai ntawm Kev Ua Phem Rau Roj Dawb
Thaum kev sib tw nce siab zuj zus hauv xyoo 2010, qee cov chaw tsim khoom tau pib diluting silicone nrog cov roj av pheej yig hu ua "roj dawb" (roj av). Qhov no sawv cev rau qhov txaus ntshai "carbon-based regression" hauv kev lag luam uas muaj silicon tswj hwm.
Vim Li Cas Cov Roj Dawb Tsis Ua Haujlwm Hauv Cov Kev Siv Hauv Tsev
Cov roj av (C_n H_{2n+2}) tsis sib haum nrog cov pob txha caj qaum $Si-O-Si$ ntawm cov polymers silicone. Qhov tsis sib haum no ua rau:
-
1. Kev tsiv teb tsaws chaw thiab kev pleev ximCov roj tawm los, ua rau cov roj "zaj sawv" lo rau ntawm iav thiab ua rau pob zeb ntuj muaj xim.
-
2. Kev Ntsws Ntau DhauThaum cov roj ua pa, cov sealant yuav ntsws ntau dua 15%, ua rau cov pob qij txha puas.
-
3. Kev Ua Tsis Tau ZooCov sealant uas tsis zoo yuav tawv thiab tawg yooj yim hauv 6 txog 24 lub hlis, ua rau muaj kev pheej hmoo loj heev uas cov iav vaj huam sib luag yuav tawg ntawm lub ntsej muag.
Kev Tswj Xyuas Zoo: Tus Txheej Txheem Siway
Txhawm rau tiv thaiv lub tsev kom ntev, Siway ua raws li cov qauv kev ua tau zoo thoob ntiaj teb zoo liASTM C1184thiabGB 16776Peb pom zoo komCov Txheej Txheem IETrau kev tswj xyuas zoo hauv qhov chaw:
-
*Kuv - Kev Tshuaj XyuasXyuas Cov Ntawv Qhia Txog Kev Siv Tshuab (TDS) thiab xyuas kom meej tias cov khoom muaj 100% silicone polymer.
-
*E - Kev Ntsuam XyuasUa kev kuaj xyuas cov qauv kuaj uas tau kho kom zoo kom paub tseeb tias lawv tseem ci ntsa iab thiab tsis ua hmoov av raws sijhawm.
-
*T - Kev NtsuasRau ob lub tshuab xws li:SV9900, siv "Kev Ntsuas Npauj Npaim" los xyuas kom meej tias muaj kev sib xyaw ua ke ntawm cov hauv paus thiab cov tshuaj catalyst.
Cov Facades Uas Muaj Kev Ruaj Ntseg Los Ntawm Kev Siv Tshuaj Purity
Kev hloov pauv ntawm phab ntsa ntaub thaiv yog ib txoj kev taug kev mus rau qhov zoo tshaj plaws ntawm cov khoom siv. Los ntawm kev xaiv cov tshuaj sealant silicone ntshiab, cov kws kes duab vajtse thiab cov engineers xyuas kom meej tias lawv cov qauv tseem ruaj khov rau 25 txog 50 xyoo.
Ntawm Siway Sealants, peb ntseeg tias "Silicon-Based Era" yuav tsum tau txhais los ntawm kev nyab xeeb thiab kev ruaj khov. Peb qhov kev cog lus "Green Sealant" ua kom txhua yam khoom tsis muaj roj dawb adulterated, tiv thaiv cov skylines ntawm tag kis nrog cov tshuaj lom neeg ntawm hnub no.
