Nakuba amapulasitiki anezakhiwo eziningi ezinhle, akuzona zonke izinhlobo zepulasitiki ezingaba nazo zonke izinto ezinhle.Onjiniyela bezinto zokwakha kanye nabaqambi bezimboni kumele baqonde izakhiwo zamapulasitiki ahlukahlukene ukuze bakhe imikhiqizo yepulasitiki ephelele.Impahla yepulasitiki, ingahlukaniswa ibe impahla ebonakalayo eyisisekelo, impahla yemishini, impahla eshisayo, impahla yamakhemikhali, impahla ye-optical kanye nempahla kagesi, njll. Amapulasitiki obunjiniyela abhekisela kumapulasitiki ezimboni asetshenziswa njengezingxenye zezimboni noma izinto zegobolondo.Zingamapulasitiki anamandla amakhulu, ukumelana nomthelela, ukumelana nokushisa, ubulukhuni kanye nezakhiwo zokulwa nokuguga.Imboni yaseJapan izoyichaza ngokuthi “ingasetshenziswa njengengxenye yesakhiwo nemishini yamapulasitiki asebenza kahle kakhulu, ukumelana nokushisa okungaphezu kuka-100 ℃, asetshenziswa kakhulu embonini”.
Ngezansi sizobhala ezinye ezivame ukusetshenziswaamathuluzi okuhlola:
1.I-Melt Flow Index(MFI):
Isetshenziselwa ukulinganisa izinga lokuncibilika lokugeleza kwenani le-MFR lamapulasitiki ahlukahlukene nama-resin asesimweni sokugeleza kwe-viscous.Ifanele amapulasitiki obunjiniyela afana ne-polycarbonate, i-polyarylsulfone, amapulasitiki e-fluorine, inayiloni nokunye okunokushisa okuphezulu okuncibilika.Futhi ifanele i-polyethylene (PE), i-polystyrene (PS), i-polypropylene (PP), i-ABS resin, i-polyformaldehyde (POM), i-polycarbonate (PC) resin kanye nezinye izinga lokushisa elincibilikayo lepulasitiki liphansi.Hlangana namazinga: ISO 1133,ASTM D1238,GB/T3682
Indlela yokuhlola ukuvumela izinhlayiya zepulasitiki zincibilike zibe uketshezi lwepulasitiki phakathi nesikhathi esithile (imizuzu eyi-10), ngaphansi kwezinga lokushisa elithile nengcindezi (amazinga ahlukene ezinto ezahlukahlukene), bese zigeleza ngobubanzi obungu-2.095mm wenani lamagremu. (g).Uma likhulu inani, ngcono uketshezi lokucubungula kwezinto zepulasitiki, futhi ngokuphambene nalokho.Izinga lokuhlola elisetshenziswa kakhulu yi-ASTM D 1238. Ithuluzi lokulinganisa laleli zinga lokuhlola i-Melt Indexer.Inqubo ethile yokusebenza yokuhlolwa yile: impahla ye-polymer (ipulasitiki) okufanele ihlolwe ifakwe emseleni omncane, futhi ukuphela komsele kuxhunywe ngeshubhu elincanyana, ububanzi balo buyi-2.095mm, nobude be-groove. ishubhu 8mm.Ngemuva kokushisa ekushiseni okuthile, umkhawulo ongaphezulu wempahla eluhlaza ucindezelwa phansi ngesisindo esithile esisetshenziswa i-piston, futhi isisindo sempahla eluhlaza silinganiswa kungakapheli imizuzu eyi-10, okuyinkomba yokugeleza yepulasitiki.Kwesinye isikhathi uzobona ukumelwa okungu-MI25g/10min, okusho ukuthi amagremu angama-25 epulasitiki akhishwe ngemizuzu eyi-10.Inani le-MI lamapulasitiki asetshenziswa ngokuvamile liphakathi kuka-1 no-25. I-MI enkulu, i-viscosity encane yezinto ezingavuthiwe zepulasitiki kanye nesisindo samangqamuzana amancane;uma kungenjalo, i-viscosity enkulu yepulasitiki kanye nesisindo samangqamuzana amakhulu.
2.Umshini Wokuhlola I-Tensile Ejwayelekile(UTM)
Umshini wokuhlola i-Universal material (umshini we-tensile): ukuhlola ukushuba, ukuklebhuka, ukugoba nezinye izakhiwo zemishini zezinto zepulasitiki.
Ingahlukaniswa ngezigaba ezilandelayo:
1)Amandla aqinile&Ukwelula:
Amandla e-tensile, aziwa nangokuthi amandla aqinile, abhekisela kusayizi wamandla adingekayo ukuze kunwetshwe izinto zepulasitiki ngokwezinga elithile, ngokuvamile elivezwa ngokuya ngokuthi angakanani amandla endaweni yeyunithi, futhi iphesenti lobude obunwetshiwe buwukwelula.Amandla okuqina Isivinini esiqinile sesifanekiso sivamise ukuba ngu-5.0 ~ 6.5mm/min.Indlela yokuhlola enemininingwane ngokuya nge-ASTM D638.
2)Amandla aguqukayo&Amandla okugoba:
Amandla okugoba, aziwa nangokuthi amandla aguquguqukayo, asetshenziswa kakhulu ukunquma ukumelana nokuguquguquka kwamapulasitiki.Ingahlolwa ngokuhambisana nendlela ye-ASTMD790 futhi ivamise ukuvezwa ngokuya ngokuthi angakanani amandla endaweni yeyunithi.Amapulasitiki avamile ku-PVC, i-Melamine resin, i-epoxy resin namandla okugoba e-polyester yiwona angcono kakhulu.I-Fiberglass iphinde isetshenziselwe ukuthuthukisa ukumelana nokugoqa kwamapulasitiki.Ukugoba nokunwebeka kubhekisela ekucindezelweni okugobayo okukhiqizwa ngeyunithi ngayinye yenani lokuwohloka ebangeni elinwebekayo lapho isifanekiso sigobile (indlela yokuhlola efana namandla okugoba).Ngokuvamile, ukunwebeka okukhulu kokugoba, kuba ngcono ukuqina kwezinto zepulasitiki.
3)Amandla acindezelayo:
Amandla okucindezela abhekisela emandleni amapulasitiki okumelana namandla okucindezela angaphandle.Inani lokuhlola linganqunywa ngendlela ye-ASTMD695.I-Polyacetal, i-polyester, i-acrylic, i-urethral resins nama-meramin resins anezakhiwo ezivelele kulokhu.
3.Umshini wokuhlola umthelela weCantilever/ Skusho umshini wokuhlola umthelela we-beam osekelwe
Isetshenziselwa ukuhlola ukuqina komthelela wezinto ezingezona ezensimbi njengephepha lepulasitiki eliqinile, ipayipi, izinto ezimise okukhethekile, inayiloni eqinisiwe, ipulasitiki eqiniswe ngefayibha yengilazi, i-ceramic, i-cast stone insulating material, njll.
Ngokuhambisana nezinga lamazwe ngamazwe le-ISO180-1992 "ipulasitiki - ukuzimisela komthelela we-cantilever wezinto eziqinile";Indinganiso kazwelonke ye-GB/ T1843-1996 “indlela yokuhlola umthelela wepulasitiki eqinile”, indinganiso yemboni yemishini i-JB/ T8761-1998 “umshini wokuhlola umthelela wepulasitiki we-cantilever”.
4.Ukuhlolwa kwemvelo: ukulingisa ukumelana nesimo sezulu sezinto.
1) I-incubator ehlala njalo, izinga lokushisa elingaguquki kanye nomshini wokuhlola umswakama yizinto zikagesi, i-aerospace, izimoto, izinto zikagesi zasendlini, upende, imboni yamakhemikhali, ucwaningo lwesayensi ezindaweni ezifana nokuzinza kwezinga lokushisa nomswakama ukuthembeka kwemishini yokuhlola, edingekayo ezingxenyeni zemboni, izingxenye eziyinhloko, imikhiqizo eqediwe kancane, ugesi, i-electronics kanye neminye imikhiqizo, izingxenye kanye nezinto zokushisa okuphezulu, izinga lokushisa eliphansi, amakhaza, umswakama kanye nezinga lokushisa elishisayo noma ukuhlolwa okuqhubekayo kwezinga lokushisa nomswakama endaweni yokuhlola.
2) Ibhokisi lokuhlola ukuguga elinembile, ibhokisi lokuhlola ukuguga kwe-UV (ukukhanya kwe-ultraviolet), ibhokisi lokuhlola izinga lokushisa eliphezulu neliphansi,
3) Isihloli Sokuthuthumela Okushisayo Esihlelekayo
4) Umshini wokuhlola umthelela obandayo noshisayo yizinto zikagesi nezikagesi, izindiza, izimoto, izinto zikagesi zasendlini, okokugqoka, imboni yamakhemikhali, imboni yezokuvikela kazwelonke, imboni yezempi, ucwaningo lwesayensi neminye imikhakha yemishini yokuhlola edingekayo, Ilungele izinguquko ezibonakalayo izingxenye nezinto zokwakha zeminye imikhiqizo enjenge-photoelectric, i-semiconductor, izingxenye ezihlobene ne-elekthronikhi, izingxenye zezimoto nezimboni ezihlobene namakhompiyutha ukuze kuhlolwe ukuphindwaphindwa kokumelana kwezinto ezisezingeni lokushisa eliphezulu neliphansi kanye noshintsho lwamakhemikhali noma ukulimala ngokomzimba kwemikhiqizo ngesikhathi sokunwetshwa okushisayo nokufinyela okubandayo. .
5) Igumbi lokuhlola elishintshanisa izinga lokushisa eliphezulu neliphansi
6)Igumbi Lokuhlola Ukumelana Nesimo Sezulu le-Xenon-lamp
7)I-HDT VICAT TESTER
