I-propellene oxide(Po) impahla evumayo eluhlaza ekwenziweni kwamakhemikhali ahlukahlukene amakhemikhali. Uhla lwayo olubanzi lwezinhlelo lubandakanya ukukhiqizwa kwe-polyurethane, ama-polytheth, nezinye izimpahla ezenzelwe ama-polymer. Ngesidingo esikhulayo semikhiqizo esekwe embonini ehlukahlukene embonini ehlukahlukene njengokwakha, izimoto, ukupakisha, nefenisha, imakethe ye-PO kulindeleke ukuthi ithole ukukhula okuphambili eminyakeni ezayo.

Abashayeli bokukhula kwemakethe

Isidingo se-PO siqhutshwa ngokuyinhloko yizimboni zokwakha ezichumayo nezimoto. Umkhakha wezokwakha okhula ngokushesha, ikakhulukazi emnothweni ovelayo, uholele ekusetshenzisweni kwesidingo sokusebenza okuphezulu nokungabizi kwezinto zokufaka izindleko. Amagwebu e-polyurethane asuselwa ku-polyurethane asetshenziswa kabanzi embonini yezokwakha ngokufakelwa kwawo okuhle kanye nezakhiwo ezilwa nomlilo.

Ngaphezu kwalokho, imboni yezimoto ibilokhu ingumshayeli obalulekile we-PO Market. Ukukhiqizwa kwezimoto kudinga i-plethora yezinto zokwakha ezingamelana namazinga okushisa aphezulu kanye nokuxineka kwemishini. Ama-polymers asuselwa ku-PO ahlangabezana nalezi zidingo futhi asetshenziswa kakhulu ekwenziweni kwezinto zezimoto.

Izinselelo Zokukhula Kwemakethe

Naphezu kwamathuba amaningi okukhula, i-PO imakethe ibhekene nezinselelo eziningana. Enye yezinselelo eziyinhloko ukuguquguquka kwamanani entengo eluhlaza. Amanani entengo yezinto ezingavuthiwe ezifana ne-propylene nomoya-mpilo, abalulekile ekukhiqizweni kwe-PO, zingaphansi kokuguquguquka okukhulu, okuholela ekuzenzekeni kwezindleko zokukhiqiza. Lokhu kungathinta inzuzo yabakhiqizi be-PO futhi kungathinta amandla abo okuhlangabezana nesidingo esikhulayo.

Enye inselelo yimithetho eqinile yemvelo ebekwe embonini yamakhemikhali. Ukukhiqizwa kukaPo kukhiqiza imfucumfucu eyingozi kanye nokuphuma kwegesi abamba ukushisa, okuholele ekuhlolweni kwenhlamvu nezinhlawulo kubaphathi abalawulayo. Ukuhambisana nale mithethonqubo, abakhiqizi be-PO badinga ukutshala imali ekwakhiweni okubizayo kwemfucuza kanye nobuchwepheshe bokulawula ukuphuma, okungakhuphula izindleko zabo zokukhiqiza.

Amathuba okukhula kwemakethe

Naphezu kwezinselelo, kunamathuba amaningana okukhula kwemakethe ye-PO. Ithuba elilodwa elinjalo yisidingo esandayo sezinto zokwakha embonini yezokwakha. Lapho umkhakha wezokwakha unwebeka emnothweni osafufusa, isidingo sezinto ezisebenza ngokusebenza kahle kulindeleke ukuba zikhuphuke. Ama-Fo-based polyurethane Foams anikela ngezakhiwo ezihlukile ezizenza zilungele izinhlelo ezahlukahlukene zokufakwa.

Elinye ithuba likhona embonini yezimoto ethuthuka ngokushesha. Ngokugxila okukhulayo emotweni okulula nokusebenza kahle kophethiloli, kunesidingo esikhulayo sezinto ezingasindi ezingakwazi ukubekezelela amazinga okushisa aphezulu kanye nezingcindezi zemishini. Ama-polmers ase-PO ahlangabezana nalezi zidingo futhi angahle athathe isikhundla sezinto zendabuko ezifana nengilazi nensimbi ekukhiqizweni kwezimoto.

Ukugcina

Isimo semakethe se-propelene oxide sihle, siqhutshwa yizimboni ezichumayo nezimoto. Kodwa-ke, ukuguquguquka ngamanani entengo eluhlaza okotshani kanye nemithetho eqinile yezemvelo kufaka izinselelo zokukhula kwezimakethe. Ukuze basebenzise amathuba ngamathuba, abakhiqizi be-PO badinga ukuhlala abajwayelene nezitayela zemakethe, batshale imali ecwaninganeni nasekuthuthukisweni, futhi bamukele izindlela zokukhiqiza ezizinzile ukuqinisekisa ukukhiqizwa okusebenzayo kanye nemvelo.
