3. Polyurethane vs. Zvimwe
KusimbisaMvumo yeMusoro, zvakakosha kunzwisisa kuti PU inobudirira papi kana tichienzanisa neSilicone kana MS Polymers.
| Chinhu | Polyurethane (PU) | Silicone | MS Polymer (Yakasanganiswa) |
| Kupenda | Zvakanakisa | Hapana (Pendi ichapetwa) | Kugona |
| Kuramba Kubvarura | Yakakwirira | Zvakaderera | Zviri pakati nepakati |
| Kuramba UV | Zvakanaka (zvine zvinosimbisa) | Zvinoshamisa | Zvakanakisa |
| Nzira Yokurapa | Kurapa hunyoro | Kurapa hunyoro | Kurapa hunyoro |
| Substrate Yakanakisisa | Konkriti, Matanda, Simbi | Girazi, Zviumbwa zvesimbi | Substrate yakawanda |
4. Kuedzwa Kwemhando Yehunyanzvi (Nyanzvi Yekunzwisisa)
Kuti uve nechokwadi chekuti uri kugamuchira zvinhu zvemhando yepamusoro kubva kwaurivagadziri vezvisimbiso, timu yako yeQC inofanira kuongorora:
1. Kureba panguva yekuzorora:Zvivharo zvePU zvemhando yepamusoro zvinofanirwa kupa kureba kwe>400% kuti zvikwanise kubata shanduko dzechimiro.
2.Modulus pa100%:Zvivharo zve "low-modulus sealants" zviri nani pamajoini ane kufamba kwakanyanya, nepo "high-modulus" iri nani pakubatanidza chivakwa.
3. Mazinga eVOC:Muna 2026, maformula eVOC mashoma haachashandiswi—iwo mutemo unodiwa kuti pave nezvitupa zvekuvaka zvakasvibira (LEED).
