Iyini i-Polyphenylene Sulphide (PPS)
I-PPS imele i-Polyphenylene Sulphide iyi-thermoplastic yobunjiniyela esebenza kahle kakhulu ehlukaniswa ngenhlanganisela yayo yezakhiwo.
I-semi-crystalline, i-opaque ne-polymer eqinile enendawo yokuncibilika ephezulu kakhulu (280°C) futhi iqukethe amayunithi e-para-phenylene ashintshana nokuxhuma kwawo kwe-sulphide.
I-PPS inokulingana okuhle kakhulu kwezakhiwo ezinjengokumelana nelangabi ngokwemvelo, ukumelana okuhle kwamakhemikhali, ukumelana nezinga lokushisa eliphezulu, amakhono obukhulu, amandla akhethekile okusebenza kanye nokufaka ugesi.
I-PPS ingacutshungulwa kalula ngoba ukuqina kwayo kuyanda ngamazinga okushisa aphezulu.
Zonke lezi zimfanelo ezinhle kakhulu zenza i-PPS ibe enye indlela enhle kakhulu yama-thermosets nezinsimbi ukuze zisetshenziswe ezinhlelweni zokusebenza ezimbalwa nezinto zikagesi, izingxenye zezimoto nezinto zikagesi.
Amakhasimende amaningi ezingxenyeni zokubumba umjovo we-PPS anohlobo lokucabanga kwe-inertia: akukho ukushisa kwesikhunta, isango alilikhulu, ukuphuma okwanele, isikhathi esifushane sokupholisa.
Izinga lokushisa lesikhunta lingenza ubuso bomkhiqizo bube crystallization ngokushesha, bushelelezi ngaphandle kokugeleza kwefayibha elintantayo, okubaluleke kakhulu ukwenza amandla omkhiqizo aqiniswe kakhulu;ubukhulu besango buthinta inani lomjovo wepulasitiki, futhi kuzoba nezidingo zokubeka ingcindezi kanye nezinga lomjovo.Kuzoba nomthelela ekulahlekeni kwengcindezi ye-distal yemikhiqizo enamaphuzu amaningi.
I-exhaust enganele izodala ukunqwabelana kwegesi ngokushesha, okuholela ekushiseni kanye nephethini ebusweni nasemsileni womkhiqizo.
I-PPS ngokwayo impahla izoqukatha i-sulfide nezinye inani elincane le-polyphenylbiphenyl polymer precipitation, ngakho-ke ukuklama kokukhipha umoya kubaluleke kakhulu!
Isikhathi esifushane sokupholisa, asihambisani nokukhanya okugcwele komkhiqizo!
Ukuze uphishekele umthamo wokukhiqiza, amakhasimende amaningi anciphisa ngokuqondile umjikelezo wokukhiqiza ngezinga elikhulu, okuholela emjikelezweni we-crystallization wezinto ezimfushane, ongahambisani nesixazululo sento yokuqala!
Ukukhetha okunengqondo kwezinto zokwakha, ukukhiqizwa kwesayensi!
Nikeza ukusekelwa kokukodwa okuvela ezintweni ezingavuthiwe, isikhunta, izinqubo, imikhiqizo eqediwe, izikhalazo zamakhasimende kanye nolunye uchungechunge olugcwele!
Izinto zokusebenza eziphezulu ezikuzungezile ochwepheshe besixazululo esisodwa-stop!
