Kev Tsim Kho Lub Zog Rov Ua Dua Tshiab
-
**Hnub Ci & Cua:Kaw cov khoom siv hluav taws xob rhiab heev thiab cov pob qij txha hauv cov hniav cua thiab cov thav duab hnub ci.
2. Xaiv Cov Neeg Muag Khoom Polyurethane Sealants Txhim Khu Kev Ntseeg Siab
Thaum xaiv cov khoom siv, tsis yog txhua yam khoom sivCov neeg muag khoom polyurethane sealantraug tsim sib npaug. Yuav kom ntseeg tau tias muaj kev ywj pheej ntawm cov khoom xa tuaj thiab cov khoom zoo, xav txog peb lub hauv paus tseem ceeb ntawm kev ua tau zoo:
Kev Ua Raws Cai thiab Daim Ntawv Pov Thawj
Qib siab tshajcov chaw tsim khoom siv foobyuav tsum ua raws li cov qauv thoob ntiaj teb uas nruj heev. Nrhiav rau:
-
**ISO 11600:Tus qauv rau cov tshuaj sealant rau kev tsim kho vaj tse.
-
ASTM C920:Cov lus qhia txheem rau cov khoom siv sib txuas elastomeric.
-
**Kev Ua Raws Cai REACH & RoHS:Tseem ceeb rau xyoo 2026 cov lus txib kom ruaj khov hauv EU thiab North American kev lag luam.
Kev Muaj Peev Xwm R&D thiab Kev Kho Kom Haum
Qhov zoo tshaj plawsCov Neeg Muag Khoom Siv Polyurethane Sealantstsis txhob tsuas yog muab cov khoom uas twb muaj lawm xwb. Lawv muab cov khoom no:
-
**Kev Kho Mob Ceev:Tsim tshwj xeeb rau cov kab sib dhos ua ke.
-
**Kev Kho Qhov Nyuaj ntawm Ntug Dej A:Kev sib phim qhov tawv ntawm cov sealant rau qhov xav tau ntawm cov substrate tshwj xeeb.
3. Polyurethane vs. Lwm Txoj Hauv Kev
Yuav tsim kom muajLub Koom Haum ntawm Cov Ncauj Lus, nws yog ib qho tseem ceeb kom nkag siab qhov twg PU zoo dua piv rau Silicone lossis MS Polymers.
| Feature | Polyurethane (PU) | Silicone | MS Polymer (Hybrid) |
| Kev pleev xim tau | Zoo heev | Tsis muaj (Cov xim yuav ci ntsa iab) | Zoo |
| Kev Tiv Thaiv Kev Tsim Kua Muag | Siab | Qis | Nruab nrab |
| Kev Tiv Thaiv UV | Zoo (nrog cov stabilizers) | Zoo kawg nkaus | Zoo heev |
| Txoj Kev Kho Mob | Kev kho kom noo noo | Kev kho kom noo noo | Kev kho kom noo noo |
| Cov Khoom Siv Zoo Tshaj Plaws | Pob zeb ua vaj tse, Ntoo, Hlau | Iav, Khoom Siv Ua Los Ntawm Av nplaum | Ntau lub substrate |
4. Kev Ntsuas Zoo ntawm Kev Siv Tshuab (Kev Nkag Siab Los Ntawm Cov Kws Tshaj Lij)
Yuav kom paub tseeb tias koj tau txais cov khoom zoo los ntawm kojcov chaw tsim khoom siv foob, koj pab neeg QC yuav tsum xyuas kom meej:
1. Kev ntev thaum tawg:Cov khoom siv foob PU zoo tshaj plaws yuav tsum muaj > 400% elongation los tswj cov kev hloov pauv ntawm cov qauv.
2. Modulus ntawm 100%:Cov sealant uas muaj modulus qis zoo dua rau cov pob qij txha uas muaj kev txav mus los siab, thaum cov modulus siab zoo tshaj plaws rau kev sib txuas ntawm cov qauv.
3. Cov Qib VOC:Xyoo 2026, cov qauv VOC qis tsis yog xaiv tau lawm - lawv yog qhov yuav tsum tau ua rau cov ntawv pov thawj tsev ntsuab (LEED).
5. Cov Lus Nug Feem Ntau (FAQ)
Kuv puas siv tau PU sealant rau ntawm cov chaw ntub dej?
Thaum qee cov qauv siab heev los ntawm cov kws tshwj xeebCov neeg muag khoom polyurethane sealanttso cai rau kev siv rau ntawm qhov chaw ntub dej, feem ntau nws raug pom zoo kom siv rau ntawm cov khoom qhuav, huv si kom ntseeg tau tias muaj kev sib txuas tshuaj lom neeg ntau tshaj plaws.
"Cov tshuaj nplaum PU yuav siv sijhawm ntev npaum li cas thiaj li kho tau?"
Feem ntau, nws tsim ib daim tawv nqaij hauv 60-90 feeb thiab kho tau ntawm tus nqi ntawm 2-3 hli txhua 24 teev, nyob ntawm seb av noo thiab kub npaum li cas.
