（China）GC-7890 I-Ditert-butyl Peroxide Residue Detector

Incazelo emfushane:

Isingeniso

Indwangu encibilikisiwe inezici zobukhulu bembobo encane, ukubhoboka okuphezulu kanye nokusebenza kahle kokuhlunga okuphezulu, futhi iyinto eyinhloko yokukhiqiza imaski. Leli thuluzi libhekisela ku-GB/T 30923-2014 plastic Polypropylene (PP) Melt-blown Special Material, efanelekile i-polypropylene njengezinto eziluhlaza eziyinhloko, ene-di-tert-butyl peroxide (DTBP) njenge-ejenti yokunciphisa, i-modified polypropylene melt-blown special material.

Izindlela isimiso

Isampula iyancibilika noma ivuvuke ku-toluene solvent equkethe inani elaziwayo le-n-hexane njengendinganiso yangaphakathi. Inani elifanele lesisombululo limuncwa yi-microsampler futhi lifakwe ngqo ku-gas chromatograph. Ngaphansi kwezimo ezithile, kwenziwa ukuhlaziywa kwe-gas chromatographic. I-DTBP residue inqunywe ngendlela yangaphakathi ejwayelekile.

7) I-Toluene, ehlanzekile ngokuhlaziya.

I-GC-7890 Gas chromatograph isebenzisa uhlelo lokulawula i-microcomputer kanye nesibonisi sesikrini esikhulu saseShayina, ukubukeka kuhle kakhulu futhi kubushelelezi. Izinkinobho zekhibhodi ezisanda kuklanywa zilula futhi ziyashesha, futhi amasekethe ayizingxenye ezingenisiwe, ngakho ukusebenza kwethuluzi kuzinzile futhi kuthembekile.

Isici sokusebenza

Ⅰ. Ukuhlanganiswa kwesekethe ephezulu, ukunemba okuphezulu, imisebenzi eminingi

1. Ukusebenza kokhiye wekhompyutha encane, isibonisi se-LCD esikhulu esingu-5.7 intshi (320*240) ngesiShayina nesiNgisi, isibonisi sesiShayina nesiNgisi singashintshwa ngokukhululeka, ukuze kuhlangatshezwane nezidingo zamaqembu ahlukene abantu, ingxoxo yomuntu nomshini, kulula ukuyisebenzisa.

2. Isitholi selangabi se-hydrogen esilawulwa yi-microcomputer ukuze kufezwe umsebenzi wokushisa ozenzakalelayo, ohlakaniphe kakhulu. Isekethe entsha yedijithali ehlanganisiwe, ukunemba okuphezulu kokulawula, ukusebenza okuzinzile nokuthembekile, ukunemba kokulawula izinga lokushisa okufika ku-0.01℃.

3. Umsebenzi wokuvikela igesi, ukuvikela ikholomu kanye nedamu lokuqhuba ukushisa, umtshina wokubamba ama-electron.

Inomsebenzi wokuzihlola lapho iqala ukusebenza, okwenza abasebenzisi bakwazi ukwazi ngokushesha imbangela kanye nendawo yokwehluleka kwethuluzi, umsebenzi wewashi lokumisa (ukulinganisa ukugeleza okulula), umsebenzi wokugcina nokuvikela ukwehluleka kwamandla, umsebenzi wokuphazamisa ukuguqulwa kwamandla, ukuxhumana kwedatha yenethiwekhi kanye nomsebenzi wokulawula kude. Umsebenzi wokuvikela ukushisa ngokweqile uqinisekisiwe

Ithuluzi alilimele futhi linesistimu yememori yedatha engadingi ukusetha kabusha ngakunye.

Ⅱ.Uhlelo lomjovo oluyingqayizivele lungaba umkhawulo wokutholwa ophansi

1. Umklamo wembobo yokujova oyingqayizivele ukuxazulula ukuhlukaniswa kokujova; Umsebenzi wokunxephezela amakholomu amabili awuxazululi nje kuphela ukukhukhuleka komugqa oyisisekelo okubangelwa izinga lokushisa elihleliwe, kodwa futhi ususa ithonya lomsindo wangemuva ukuze uthole umkhawulo ophansi wokutholwa.

2.Ngekholomu egcwele, uhlelo lomjovo we-capillary shunt/non-shunt (onomsebenzi wokuhlanza i-diaphragm)

3. I-injector yegesi ezenzakalelayo/esebenzisa isandla eyisithupha, i-injector ye-headspace, i-injector yesisombululo sokushisa, i-converter ye-methane, i-injector ezenzakalelayo.

Ⅲ, Izinga lokushisa elihleliwe, ukulawula izinga lokushisa kwesithando esinembile, ukuzinza okusheshayo

1. Izinga lokushisa eliqondile elihleliwe nge-oda eziyisishiyagalombili, ngemuva komnyango kusetshenziswa umklamo wokushintsha kwe-photoelectric okungenathinta, othembekile futhi ohlala isikhathi eside, ohlakaniphile ngemuva kohlelo lomnyango oluguquguqukayo olungenasinyathelo, ufushanisa uhlelo ngemuva kokwenyuka/ukwehla kwesikhathi sokulinganisela esizinzile sohlelo lomtshina, uqaphele ngempela ukusebenza kokushisa kwegumbi eliseduze, ukunemba kokulawula izinga lokushisa okungu-±0.01℃, kuhlangabezana nezidingo zohlu olubanzi lokuhlaziya.

2. Umthamo omkhulu webhokisi lekholomu, uhlelo oluhlakaniphile lomnyango wangemuva olungenazinyathelo, umoya oguquguqukayo ongena futhi ophumayo, ufushanisa uhlelo ngemva kokuphakamisa/ukupholisa uhlelo lokuthola isikhathi sokulinganisela esizinzile; Uhlelo lokushisa isithando somlilo: izinga lokushisa elizungezile +5℃ ~ 420℃.

3. Umphumela wokushisa ungcono: ibhokisi lekholomu, ukuhwamuka, ukutholwa kungama-degrees angu-300, ibhokisi langaphandle kanye nesembozo esiphezulu kungaphansi kwama-degrees angu-40, kuthuthukisa izinga lokuhlola, ukuqinisekisa ukuphepha komsebenzisi.

4. Umklamo oyingqayizivele wegumbi lokufutha, ivolumu encane efile; Ukufakwa esikhundleni kwezesekeli: iphedi yomjovo, i-liner, i-polarizer, i-collector, i-nozzle ingashintshwa ngesandla esisodwa; Ukufakwa esikhundleni komzimba oyinhloko: ikholomu yokugcwalisa, i-capillary sampler kanye ne-detector kungasuswa ngokuphelele nge-wrench kuphela, kulula ukuyilungisa.

Ukuzwela okuphezulu, isitholi sokuqina okuphezulu, esihlangabezana nezidingo zezinhlelo ezahlukene

Isitholi se-ionization se-hydrogen flame (FID), isitholi se-thermal conductivity cell (TCD), isitholi se-electron capture (ECD),

Isitholi se-Flame Photometric (FPD), Isitholi se-Nitrogen ne-Phosphorus (NPD)

Zonke izinhlobo zezitholi zingalawulwa ngokuzimela izinga lokushisa, kulula ukuzihlukanisa nokuzifaka, kulula ukuzihlanza noma ukuzishintsha i-nozzle.
