Njengomkhiqizi womhlaba wonke ogxile kuizinto zokuvala ze-silicone, izinto zokuvala i-polyurethane (PU), Izinhlelo zokunamathela ze-PU, futhiizixazululo zokuvimbela amanzi ezakhiweni, ISiwayinikeza kokubili amakhemikhali futhi iyaqonda amandla kanye nokulinganiselwa kwawo kusuka ku-isayensi yezinto ezibonakalayo, ubunjiniyela, futhiokusekelwe kuhlelo lokusebenzaumbono.
Lo mhlahlandlela unikezaukuqhathanisa okuphelele kakhulu nokunegunyaye-PU vs. i-silicone—esekelwa yiIzindlela zokuhlola ze-ASTM/ISO, izimiso zokuhlola elebhu, futhiukuqonda kohlelo lokusebenza lwangempelakusukela ekukhiqizeni kukaSiway kanye nolwazi lwamakhasimende.
1. I-Material Chemistry kanye Nokuziphatha Kwesakhiwo
1.1 Izivalo ze-Polyurethane (i-Organic Polymer Chemistry)
Ama-polyurethane sealant (PU) asekelwe ekusabeleni phakathi kwama-polyol nama-isocyanates, akha i-i-elastomer ephilayo exhumeneLesi sakhiwo sinikeza ama-sealant e-PU:
-
--Ukumelana okukhulu nezinyembezi
-
--Ukunamathela okuqinile ezisekelweni ezinezimbobo
-
--Ukumelana nokuklwebheka okuphezulu kakhulu
-
