Ubwino
1. Kuchepetsa kulemera kumawapangitsa kukhala opepuka.
2. Zida zabwino kwambiri zotentha komanso zotulutsa mawu.
3. Kukana bwino kukhudzana ndi mankhwala.
4. Sizimatulutsa okosijeni kapena kuwononga ndipo sizilowa madzi.
5. Chifukwa cha kuuma kwake kochepa mkati, kutaya katundu kumakhala kochepa.
6. Siziwonjezera ma oxides achitsulo m'madzi.
7. Kukana kwamphamvu kwamphamvu komanso kukana kwamphamvu kwambiri, chifukwa amatha kuwonjezera kutalika kwake asanaswe.
Chiyambi cha Zamalonda
PPSU ndi amorphous matenthedwe pulasitiki ndi mkulu mandala ndi mkulu hydrolytic bata. Nkhaniyi ikhoza kuchitidwa mobwerezabwereza. komanso ngati zinthu zolimbana ndi kutentha kwambiri, kutentha kosagwira kutentha kumafika madigiri 207. Chifukwa cha mobwerezabwereza kutentha otentha, nthunzi yotseketsa. Ili ndi kukana kwamankhwala kwabwino kwambiri komanso kukana kwa asidi ndi alkali, imatha kupirira mankhwala ambiri amadzimadzi ndi kuyeretsa zotsukira, sizingabweretse kusintha kwamankhwala. Zopepuka, zosagwirizana ndi kugwa, ndizabwino kwambiri pachitetezo, kukana kutentha, kukana kwa hydrolysis komanso kukana kwamphamvu.
Mapaipi olumikizira opangidwa ndi zinthu za PPSU amatha kukana kukhudzidwa kwamphamvu ndi mankhwala popanda kuwonongeka. PPSU zovekera chitoliro ndi mofulumira kukhazikitsa, zosavuta kukhazikitsa, kusindikiza wangwiro, kuonetsetsa kulumikiza kwa nthawi yaitali otetezeka, ndi kukwaniritsa phindu pazipita malire, potero kuchepetsa ntchito cost.Thes olowa ndi fungo ndi kukoma, oyenera kumwa madzi.
