Ama-polythert polyols adlala indima ebalulekile embonweni, ezinamathela, ama-sealants, kanye nezimboni ze-elastomers. Izakhiwo zayo ezihlukile zamakhemikhali zikwenza kube yingxenye ebalulekile ekunikezelweni okuhlukahlukene komkhiqizo, ukusiza ukuthuthukisa ukusebenza, ukuqina nokusebenza.
Ama-polytheare polyols anamakhompiyutha aphezulu ama-polymerized kusuka ezintweni ezingavuthiwe ezifana ne-proplemate oxide (PO) noma i-Ethylene oxide (EO). Amabhodlela e-ether (-O-) emaketangeni awo ama-molecular avuse izinto ezinokuguquguquka okuhle kakhulu, ukumelana ne-hydrolysis kanye nokuqina okushisa okuphansi. Ngokushintsha isisindo se-molecular, ukusebenza kanye nokwakheka, ama-polythea ama-polyols angaqondanisa ngqo nezidingo zokusebenza kwamacala, abe yisihluthulelo sokwenza ngcono ukuncintisana kwemikhiqizo.
Ensimini yezembatho, kusetshenziselwa ukwenza izimbobo ezisezingeni eliphakeme ezihlinzeka ngokuvikelwa kokugqwala, ukugqokwa kanye nezinto zemvelo.Isibonelo, ukwakhiwa okusekelwe kwezimboni, ukwenziwa kwama-polyther pollol kunama-adhesion amahle kakhulu. Singenza futhi ngokwezifiso ama-polytheate pollols ukulungisa isikhathi sokumisa nobulukhuni be-coating.
Abalaziswe ama-polytheate ama-polyols anezindawo ezinamathela ngokunamathela, futhi angabopha ngempumelelo izinto ezahlukene ndawonye, kungaba emhlanganweni wezingxenye zezimoto, ukukhiqizwa kwefenisha, noma ukwakhiwa kwezakhiwo.
Ama-polytheate polyols nawo asetshenziselwa ukudala izimpawu zokuvimba ukungena kwamanzi, umoya, uthuli kanye nokunye okungcolisayo. Embonini yezokwakha, ama-polytheare pollolt-based sealants ngokuvamile asetshenziswa eduze kweminyango, amawindi kanye namalunga ezakhiwo. Labolwatali bangazivumelanisa nezindawo ezingekho emthethweni, ukuhlinzeka izithiyo ezingangenzi manzi nezindiza. Banokumelana kahle nokuguga nokuguga.
Elastomer made of polyether polyols with high flexibility and is famous for its excellent mechanical properties.They are used in various applications such as automobile tires, gaskets, and vibration damping components.In tires, polyether polyol based elastomers contribute to better traction, reduced rolling resistance, and improved durability.
ThintaInikeza uhla oluphelele lwemikhiqizo ye-poly-polyther polylel polylol, emboza izinsimbi ezihlukile zamangqamuzana, ukusebenza, kanye ne-EO / PORIOS. Imikhiqizo kaDotachem isebenza abakhiqizi beGlobal Case ngekhwalithi ezinzile, ukusebenza okuvelele kanye nohlelo lokusebenza lobuchwepheshe bohlelo lwezobuchwepheshe. Vakashela ikhasi lomkhiqizo le-Dotachem eligcwele uhla lwe-ama-polythert polyols ecashile!
