Nakuba amapulasitiki enezakhiwo eziningi ezinhle, akuzona zonke izinhlobo zamapulasitiki ezingaba nazo zonke izakhiwo ezinhle. Onjiniyela bezinto zokwakha kanye nabaklami bezimboni kumele baqonde izakhiwo zamapulasitiki ahlukahlukene ukuze baklame imikhiqizo yepulasitiki ephelele. Impahla yepulasitiki, ingahlukaniswa ibe yimpahla eyisisekelo yomzimba, impahla yemishini, impahla yokushisa, impahla yamakhemikhali, impahla yokukhanya kanye nempahla kagesi, njll. Amapulasitiki obunjiniyela abhekisela kumapulasitiki ezimboni asetshenziswa njengezingxenye zezimboni noma izinto zegobolondo. Ziyipulasitiki ezinamandla amahle kakhulu, ukumelana nokushayisana, ukumelana nokushisa, ubulukhuni kanye nezakhiwo zokulwa nokuguga. Imboni yaseJapan izoyichaza ngokuthi “ingasetshenziswa njengezingxenye zesakhiwo nezemishini zamapulasitiki asebenza kahle kakhulu, ukumelana nokushisa okungaphezu kuka-100℃, ikakhulukazi ezisetshenziswa embonini”.
Ngezansi sizobala ezinye ezisetshenziswa kakhuluamathuluzi okuhlola:
1.Inkomba Yokugeleza Kokuncibilika(I-MFI):
Isetshenziselwa ukukala izinga lokugeleza kokuncibilika kwe-MFR kwepulasitiki ehlukahlukene nama-resin esimweni sokugeleza okuqinile. Ifaneleka kumapulasitiki obunjiniyela njenge-polycarbonate, i-polyarylsulfone, ipulasitiki ye-fluorine, i-nylon njalonjalo enokushisa okuphezulu kokuncibilika. Ifaneleka futhi kwi-polyethylene (PE), i-polystyrene (PS), i-polypropylene (PP), i-ABS resin, i-polyformaldehyde (POM), i-polycarbonate (PC) resin kanye nezinye izinga lokushisa lokuncibilika kwepulasitiki. Kuyivivinyo eliphansi. Hlangana namazinga: ISO 1133, ASTM D1238, GB/T3682
Indlela yokuhlola ukuvumela izinhlayiya zepulasitiki zincibilike zibe uketshezi lwepulasitiki zingakapheli isikhathi esithile (imizuzu eyi-10), ngaphansi kwezinga lokushisa elithile kanye nengcindezi (izindinganiso ezahlukene zezinto ezahlukahlukene), bese ziphuma ngobubanzi obungu-2.095mm wenani lamagremu (g). Uma inani likhulu, kuba ngcono uketshezi lokucubungula kwezinto zepulasitiki, futhi okuphambene nalokho. Izinga lokuhlola elisetshenziswa kakhulu yi-ASTM D 1238. Ithuluzi lokulinganisa lale nqubo yokuhlola yi-Melt Indexer. Inqubo ethile yokusebenza yokuhlolwa yile: izinto ze-polymer (zepulasitiki) ezizohlolwa zifakwa emseleni omncane, kanti ukuphela komsele kuxhunywe ngethubhu elincane, ububanzi balo obungu-2.095mm, kanti ubude bethubhu bungu-8mm. Ngemva kokushisa kufike ekushiseni okuthile, ingxenye engenhla yezinto zokusetshenziswa icindezelwa phansi ngesisindo esithile esisetshenziswa yi-piston, futhi isisindo sezinto zokusetshenziswa silinganiswa zingakapheli imizuzu eyi-10, okuyinkomba yokugeleza kwepulasitiki. Ngezinye izikhathi uzobona ukumelwa kwe-MI25g/10min, okusho ukuthi amagremu angu-25 epulasitiki akhishwe ngemizuzu eyi-10. Inani le-MI lamapulasitiki asetshenziswa njalo liphakathi kuka-1 no-25. Uma i-MI inkulu, kulapho i-viscosity yezinto zokusetshenziswa zepulasitiki iba ncane khona kanye nesisindo sama-molecule sibe sincane; ngaphandle kwalokho, i-viscosity yepulasitiki iba nkulu futhi isisindo sama-molecule sibe sikhulu.
2. Umshini Wokuhlola Ukunamathela Ojwayelekile (UTM)
Umshini wokuhlola izinto ezisetshenziswayo (umshini wokudonsa): ukuhlola ukudonswa, ukuklebhula, ukugoba kanye nezinye izakhiwo zemishini zezinto zepulasitiki.
Kungahlukaniswa ngezigaba ezilandelayo:
1)Amandla okudonsa&Ukwelulwa:
Amandla okudonseka, aziwa nangokuthi amandla okudonseka, abhekisela kubukhulu bamandla adingekayo ukwelula izinto zepulasitiki ngezinga elithile, ngokuvamile abonakaliswa ngokuya ngokuthi angakanani amandla endaweni ngayinye, futhi iphesenti lobude bokwelula liwukunwebeka. Amandla okudonseka Ijubane lokudonseka lesampula livame ukuba ngu-5.0 ~ 6.5mm/min. Indlela yokuhlola enemininingwane ngokusho kwe-ASTM D638.
2)Amandla aguquguqukayo&Amandla okugoba:
Amandla okugoba, aziwa nangokuthi amandla okugoba, asetshenziswa kakhulu ukunquma ukumelana nokugoba kwamapulasitiki. Angahlolwa ngokuhambisana nendlela ye-ASTMD790 futhi avame ukuvezwa ngokuya ngokuthi angakanani amandla endaweni ngayinye. Amapulasitiki ajwayelekile ku-PVC, i-Melamine resin, i-epoxy resin kanye namandla okugoba e-polyester angcono kakhulu. I-Fiberglass nayo isetshenziselwa ukuthuthukisa ukumelana nokugoba kwamapulasitiki. Ukugoba ukugoba kubhekisela ekucindezelekeni kokugoba okukhiqizwa ngeyunithi ngayinye yenani lokuguquguquka kububanzi be-elastic lapho isampula igobile (indlela yokuhlola njengamandla okugoba). Ngokuvamile, lapho ukugoba kukhulu, kuba ngcono ukuqina kwezinto zepulasitiki.
3)Amandla okucindezela:
Amandla okucindezela abhekisela ekhonweni lamapulasitiki lokumelana namandla okucindezela angaphandle. Inani lokuhlola linganqunywa ngokwendlela ye-ASTMD695. Ama-polyacetal, i-polyester, i-acrylic, ama-urethral resins kanye nama-meramin resins anezakhiwo ezivelele kulokhu.
3.Umshini wokuhlola umthelela we-Cantilever/ Sumshini wokuhlola umthelela womsebe osekelwayo
Isetshenziselwa ukuhlola ukuqina komthelela wezinto ezingezona ezensimbi njengephepha lepulasitiki eliqinile, ipayipi, izinto ezimise okwehlukile, i-nylon eqinisiwe, ipulasitiki eqinisiwe yefayibha yengilazi, i-ceramic, izinto zokuvikela zikagesi zamatshe aqoshiwe, njll.
Ngokuhambisana ne-ISO180-1992 ejwayelekile yamazwe ngamazwe “ukunqunywa kwamandla omthelela we-cantilever yepulasitiki – izinto eziqinile”; Indlela kazwelonke yokuhlola umthelela we-cantilever yepulasitiki eqinile “ye-GB/ T1843-1996” ejwayelekile, “umshini wokuhlola umthelela we-cantilever yepulasitiki” ejwayelekile embonini yemishini.
4. Ukuhlolwa kwemvelo: ukulingisa ukumelana nesimo sezulu kwezinto zokwakha.
1) Umshini wokuhlola izinga lokushisa eliqhubekayo, umshini wokuhlola izinga lokushisa eliqhubekayo kanye nomswakama yimishini kagesi, izindiza, izimoto, izinto zasekhaya, upende, imboni yamakhemikhali, ucwaningo lwesayensi ezindaweni ezifana nokuqina kokuthembeka kwemishini yokuhlola izinga lokushisa kanye nomswakama, okudingekayo ezingxenyeni zemboni, izingxenye eziyinhloko, imikhiqizo eqediwe kancane, ugesi, izinto zikagesi kanye neminye imikhiqizo, izingxenye nezinto zokwakha izinga lokushisa eliphezulu, izinga lokushisa eliphansi, ukubanda, okumanzi kanye nokushisa noma ukuhlolwa okuqhubekayo kokuhlolwa kwendawo yokushisa kanye nomswakama.
2) Ibhokisi lokuhlola ukuguga okunembile, ibhokisi lokuhlola ukuguga le-UV (ukukhanya kwe-ultraviolet), ibhokisi lokuhlola lokushisa eliphezulu neliphansi,
3) Isivivinyo Sokushaqeka Kokushisa Esingahleleka
4) Umshini wokuhlola umthelela obandayo noshisayo ungokagesi nokagesi, izindiza, izimoto, izinto zasekhaya, izembozo, imboni yamakhemikhali, imboni yezokuvikela kazwelonke, imboni yezempi, ucwaningo lwesayensi kanye neminye imikhakha imishini yokuhlola edingekayo, Ifanele izinguquko ezibonakalayo zezingxenye nezinto zeminye imikhiqizo efana ne-photoelectric, i-semiconductor, izingxenye ezihlobene ne-elekthronikhi, izingxenye zezimoto kanye nezimboni ezihlobene nekhompyutha ukuze kuhlolwe ukumelana okuphindaphindiwe kwezinto ekushiseni okuphezulu nokuphansi kanye nezinguquko zamakhemikhali noma umonakalo ongokwenyama wemikhiqizo ngesikhathi sokwanda kokushisa kanye nokuncipha kokubanda.
5) Igumbi lokuhlola elishintshashintshayo lokushisa eliphezulu neliphansi
6) Igumbi Lokuhlola Ukumelana Nesimo Sezulu Sesibani Se-Xenon
7) ISIVIVISI SE-HDT VICAT
