Cov tshuaj nplaum silicone rau kev tsim kho yog ib qho khoom siv zoo tshaj plaws hauv kev tsim kho, tsim los daws cov teeb meem tseem ceeb uas cov tshuaj nplaum ib txwm muaj tsis tuaj yeem ua tau. Ua ib qho polymer elastomeric ua tau zoo heev, nws muaj cov yam ntxwv zoo sib xws rau kev ruaj khov ntawm cov qauv, tiv taus huab cua, thiab ua haujlwm tau ntev.
Kev Sib xyaw thiab Txoj Cai
Ua los ntawm cov silicone polymers uas muaj silica txhawb, cov sealants no kho tau los ntawm acetoxy lossis cov txheej txheem tsis muaj zog kom ua tau cov elastomers ruaj khov thiab yoog tau. Cov yam ntxwv tseem ceeb ntawm molecular suav nrog:
1. Siloxane backbone muab kev ruaj khov UV thiab thermal tsis kam
2. Cov pab pawg ua haujlwm ua rau cov khoom siv sib txuas ua ke
3. Cov tshuaj ntxiv (fungicides, adhesion promoters) txhim kho kev ua tau zoo
Cov Kev Zoo Tseem Ceeb ntawm Kev Ua Haujlwm
1. Kev Pabcuam Kev Txav Mus Los ntawm Cov Qauv
- Tswj tau qhov ruaj khov los ntawm ± 50% kev txav ntawm cov pob qij txha (ASTM C920 tus qauv), tiv thaiv kev tawg ntawm kev ntxhov siab hauv cov khoom vaj khoom tsev uas hloov pauv tau.
2. Kev Ruaj Ntseg Ib puag ncig Zoo Kawg Nkaus
Ua tau zoo thoob plaws -73 ° C txog + 260 ° C yam tsis muaj kev puas tsuaj thermoplastic, ua tau zoo dua lwm cov organic polymer.
3.Kev Tiv Thaiv Lub Hnab Ntawv Tsev
Tsim cov teeb meem dej tsis tu ncua, tseem ceeb rau:
- Cov txheej txheem phab ntsa ntaub thaiv
- Cov txheej txheem sib koom ua ke
- Daim ntawv thov kev sib khi ntawm qhov chaw
4. Kev Sib Piv Khoom Siv
Cov ntawv cog lus zoo rau ntau yam substrates suav nrog:
Iav | Anodized Aluminium | Pob Zeb | Granite | PVC Tsis ua rau galvanic corrosion lossis degreasion.
5. Kev Ua Haujlwm Huv Si
Cov tshuaj uas tau ntawv pov thawj los ntawm NSF tiv thaiv kev loj hlob ntawm cov kab mob me me hauv cov chaw ntub dej (ib puag ncig pas dej ua ke, cov chaw ua zaub mov).
Cov Lus Qhia Txog Kev Siv Tshuab
| Vaj tse | Hom Acetoxy | Hom Nruab Nrab |
|---|---|---|
| Kev Kho Mob | Acetic Acid | Cawv/Ketoxime |
| Kev Sib Txuas Lus ntawm Cov Khoom Siv | Cov hlau tsis yog hlau | Txhua yam khoom siv |
| Kub thiab txias rau kev pabcuam | -50°C txog 180°C | -73°C txog 260°C |
| Kev Muaj Peev Xwm Txav Mus Los | ±25% | ±50% |
Cov Txheej Txheem Thov Kev Tsim Kho
1. Kev Npaj Nto
Kev ntxuav cov kuab tshuaj (isopropyl cawv)
Kev puas tsuaj rau ntawm cov nplaim uas tsis muaj qhov
Daim ntawv thov primer qhov twg tau teev tseg
2. Kev Txhim Kho Qhov Tseeb
Kev teeb tsa tus pas nrig backer rau cov pob qij txha > 6 hli
Lub kaum sab xis ntawm 45 ° ntawm qhov siab tas li
Cov cuab yeej siv hauv 10 feeb ntawm kev siv
3. Kev Tshawb Fawb Txog Kev Kho Mob
Kev tsim tawv nqaij: 15-30 feeb
Kho tag nrho: 24-72 teev (nyob ntawm qhov tob)
Cov nyhuv ntawm kev ua kom av noo sai dua
Kev Ua Raws Cai
Cov qauv ua thawj coj ntsib:
ASTM C920 Chav Kawm 100/50 cov kev cai
ISO 11600 F&G kev faib tawm
Cov qhab nia ntawm cov ntaub ntawv LEED v4.1
