Amapulasitiki obunjiniyela (owaziwa nangokuthi izinto zokusebenza) ayikilasi lezinto ze-polymer ezisebenza kahle kakhulu ezingasetshenziswa njengezinto zokwakha ukumelana nokucindezeleka komshini phezu kwamazinga okushisa ahlukahlukene kanye nasezindaweni ezifunwa kakhulu zamakhemikhali nezomzimba. Kuyikilasi lezinto ezisebenza kahle kakhulu ezinamandla alinganiselayo, ukuqina, ukumelana nokushisa, ubulukhuni, kanye nezakhiwo zokulwa nokuguga, futhi liyinto ebalulekile embonini yepulasitiki.
Amapulasitiki amahlanu obunjiniyela asetshenziswa kakhulu ahlanganisa i-polycarbonate (PC), i-polyamide (PA), i-polyoxymethylene (POM), i-polyphenylene ether eguquliwe (m-PPE) ne-polybutylene terephthalate (PBT), ngayinye enezici zayo.
1. I-Polycarbonate (PC): Eyaziwa ngokusobala kwayo okuphezulu kanye nokumelana nomthelela, isetshenziswa kakhulu ezintweni zezindlu kanye nezingxenye ze-optical ezidinga ukudluliswa kokukhanya. Kodwa-ke, izinto ze-PC azimelani kakhulu namakhemikhali.
2. I-Polyamide (PA, inayiloni): inamandla amahle kakhulu okusebenza aphezulu kanye nokumelana nemihuzuko, futhi imvamisa isetshenziselwa izingxenye eziwumshini njengamagiya namabheringi. Kodwa-ke, ngenxa ye-hygroscopicity yayo ephezulu, izinguquko zobukhulu zingase zenzeke ezindaweni ezinomswakama ophezulu.
3. I-Polyoxymethylene (POM): Inokumelana nokugqokwa okuhle kanye nendawo ebushelelezi, futhi isetshenziswa kakhulu njengempahla yezingxenye zemishini njengamagiya, ama-bearings kanye nemithombo ye-resin. Ukubukeka kwayo kuvamise ukuba mhlophe opaque Milky.
4. I-polyphenylene ether eshintshiwe (m-PPE): ngamandla amakhulu emishini nezici ezingasindi, ezifanele amagobolondo emishini kagesi nokunye. Nokho, ayimelani namakhemikhali.
5. i-polybutylene terephthalate (PBT): enokufakwa kahle kukagesi kanye nendawo ebushelelezi futhi ethandwayo, evame ukusetshenziswa ezingxenyeni zempahla kagesi kanye nezingxenye zikagesi zezimoto. Kodwa-ke, izinto ze-PBT zilula ukwenza i-hydrolyse futhi zithinte ikhwalithi yemikhiqizo.
Ngenxa yezakhiwo zabo eziyingqayizivele zomzimba namakhemikhali, lawa mapulasitiki wobunjiniyela adlala indima ebalulekile embonini yesimanje futhi ayaqhubeka nokwandisa ukusetshenziswa kwawo emikhakheni ehlukahlukene. Amapulasitiki obunjiniyela asetshenziswa kakhulu emikhakheni eminingi ngenxa yezakhiwo zawo ezinhle kakhulu, kodwa asabhekene nezinselelo eziningi zokucubungula, njengokusebenza kabi kokugcoba kanye nokusebenza kabi kokukhishwa kwesikhunta.
Ukusebenza kokukhishwa kwamapulasitiki obunjiniyela kubhekisela emandleni epulasitiki ukuphuma esikhunjeni kahle ngemva kokwakhiwa esikhunjeni. Ukuthuthukisa ukusebenza kokukhishwa kwamapulasitiki obunjiniyela kubaluleke kakhulu ekuthuthukiseni ukusebenza kahle kokukhiqiza, ukunciphisa amaphutha emikhiqizweni kanye nokwelula impilo yesevisi yesikhunta.
Okulandelayo izindlela ezimbalwa zokuthuthukisa ukusebenza kokukhishwa kwamapulasitiki obunjiniyela:
1. Ukwelashwa kwesikhunta:Ukungqubuzana phakathi kwepulasitiki kanye nesikhunta kungancishiswa ngokusebenzisa i-ejenti yokukhululwa ebusweni besikhunta noma ngokufaka ukwelashwa okukhethekile kokugqoka, ngaleyo ndlela kuthuthukise ukusebenza kokukhululwa. Isibonelo, ukusebenzisa amafutha amhlophe njenge-ejenti yokukhulula isikhunta.
2. Ukulawulwa kwezimo zokubumba:Ukucindezela okufanelekile komjovo, izinga lokushisa kanye nesikhathi sokupholisa kunomphumela obalulekile ekusebenzeni kokukhululwa. Ukucindezelwa komjovo okudlulele kanye nezinga lokushisa kungabangela ipulasitiki ukuthi inamathele esikhunjeni, kuyilapho isikhathi sokupholisa esingafanele singaholela ekwelapheni ngaphambi kwesikhathi noma ekuwohlokeni kwepulasitiki.
3. Ukugcinwa njalo kwesikhunta: Ukuhlanza njalo nokugcinwa kwesikhunta ukuze kukhishwe izinsalela futhi kugqoke ezindaweni ezibunjiwe kanye nokugcina isikhunta sisesimweni esihle.
4. Ukusetshenziswa kweizithasiselo:Ukwengeza izithasiselo ezithile kupulasitiki, njengezithambisi zangaphakathi noma zangaphandle, kunganciphisa ukungqubuzana kwangaphakathi kwepulasitiki kanye nokungqubuzana nesikhunta futhi kuthuthukise ukusebenza kokukhishwa.
SILIKE SILIMER 6200,Izixazululo ezisebenzayo zokuthuthukisa ukukhishwa kwamapulasitiki obunjiniyela
Ngempendulo yamakhasimende,SILIKE SILIMER 6200isetshenziswa kumapulasitiki obunjiniyela ukuze kuthuthukiswe kakhulu ukugcotshwa kwenqubo nokuthuthukisa ukusebenza kokukhishwa kwesikhunta. I-SILIKE SILIMER 6200 iphinde isetshenziswe njengesengezo sokucubungula isithambisi ezinhlobonhlobo zama-polymer. Ihambisana ne-PP, PE, PS, ABS, PC, PVC, TPE, ne-PET. Qhathanisa nalezo zithako zangaphandle ezivamile njenge-Amide, i-Wax, i-Ester, njll, isebenza kahle kakhulu ngaphandle kwenkinga yokufuduka.
Ukusebenza okujwayelekile kweSILIKE SILIMER 6200:
1) Thuthukisa ukucutshungulwa, unciphise i-torque ye-extruder, futhi uthuthukise ukuhlakazeka kwesigcwalisi;
2) I-lubricant yangaphakathi nangaphandle, yehlisa ukusetshenziswa kwamandla futhi ikhulise ukusebenza kahle kokukhiqiza;
3) inhlanganisela futhi igcina izakhiwo zemishini ye-substrate ngokwayo;
4) Yehlisa inani le-compatibilizer, yehlisa amaphutha omkhiqizo;
5) Ayikho imvula ngemva kokuhlolwa okubilayo, gcina ubushelelezi besikhathi eside.
UkungezaSILIKE SILIMER 6200ngenani elifanele linganikeza imikhiqizo yepulasitiki yobunjiniyela ukuthambisa okuhle, ukukhululwa kwesikhunta. Kuphakanyiswa amazinga okungezwa phakathi kuka-1 ~ 2.5%. Ingasetshenziswa enqubweni yokuhlanganisa ye-classical melt efana ne-Single / Twin screw extruder, ukubumba umjovo kanye nokuphakelayo kwaseceleni. Kunconywa inhlanganisela engokwenyama namapellets e-polymer emsulwa.
Uma ufuna isixazululo sokuthuthukisa izakhiwo zokukhishwa kwezipulasitiki zobunjiniyela, xhumana no-SILIKE ngenqubo yokulungiswa kwepulasitiki eyenziwe ngokwezifiso.
