Inzuzo
1. Isisindo esincane sibenza babe lula.
2. Izinto zokuvikela ukushisa nomsindo ezingcono kakhulu.
3. Ukumelana okungcono nokuchayeka kumakhemikhali.
4. Azikhiqizi i-oxidize noma zibole futhi azingeni manzi.
5. Ngenxa yobunzima bayo bangaphakathi obuphansi, ukulahlekelwa umthwalo kuncane.
6. Ayifaki ama-oxide ensimbi emanzini.
7. Ukumelana okunamandla komthelela kanye nokumelana nokucindezela okuphezulu, ngoba kungandisa ubude ngaphambi kokuphuka.
Isingeniso Somkhiqizo
I-PPSU iyipulasitiki eshisayo engenasimo esibonakalayo ephezulu kanye nokuqina okuphezulu kwe-hydrolytic. Ingafakwa ekuhlanzeni ngomusi ophindaphindwayo. Futhi njengezinto ezinokumelana nokushisa okuhle kakhulu, izinga lokushisa elingamelana nokushisa lifinyelela kuma-degrees angu-207. Ngenxa yokubila okuphindaphindiwe kokushisa okuphezulu, ukuhlanza ngomusi. Inokumelana okuhle kakhulu nemithi kanye nokumelana ne-asidi ne-alkali, ingamelana nokuhlanza okujwayelekile koketshezi kanye nensipho, ngeke ikhiqize izinguquko zamakhemikhali. Ilula, imelana nokuwa, iyona engcono kakhulu ngokuphepha, ukumelana nokushisa, ukumelana ne-hydrolysis kanye nokumelana nomthelela.
Amajoyinti okufaka amapayipi akhiqizwe ngezinto ze-PPSU angamelana nokushaqeka okunamandla kanye namakhemikhali ngaphandle komonakalo. Amajoyinti okufaka amapayipi e-PPSU ayashesha ukufakwa, kulula ukuwafaka, avala kahle, aqinisekisa ukuxhumana okuphephile kwesikhathi eside, futhi athola inzuzo ephezulu, ngaleyo ndlela anciphise izindleko zabasebenzi. Lawa majoyinti awanaphunga futhi awanambitheki, afanelekela amanzi okuphuza.
