DRK-GC-7890 Ditert-butyl peroxide zotsalira detector

Mawu Oyamba

Nsalu zosungunula zimakhala ndi mawonekedwe ang'onoang'ono pore, porosity kwambiri komanso kusefera kwapamwamba, ndipo ndiye chinthu chofunikira kwambiri popanga chigoba.Chida ichi chimatanthawuza GB/T 30923-2014 pulasitiki Polypropylene (PP) Melt-blown Special Material, yoyenera polypropylene monga zopangira zazikulu, ndi di-tert-butyl peroxide (DTBP) monga kuchepetsa wothandizira, kusinthidwa polypropylene kusungunula-kuphulika. zinthu zapadera.

Njira mfundo

Chitsanzocho chimasungunuka kapena kutupa mu zosungunulira za toluene zomwe zili ndi n-hexane yodziwika ngati muyezo wamkati.Mulingo woyenera wa yankho udamwedwa ndi microsampler ndikulowetsa mwachindunji mu chromatograph yamafuta.Pazifukwa zina, kusanthula kwa gasi chromatographic kunachitika.Zotsalira za DTBP zidatsimikiziridwa ndi njira yamkati.

Zida zazikulu ndi ma reagents

1) Chromatograph ya mpweya, cholowera cha capillary, chowunikira cha FID,

2) Unikani malire

3) Mzere wa kapilari: AT.624 30m*0.32mm*1.8μm,

4) Chromatographic workstation software,

5) N-hexane, chromatographic koyera;

6) Di-tert-butyl peroxide, kusanthula koyera;

7) Toluene, kusanthula koyera.

GC-7890 Gas chromatograph imagwiritsa ntchito makina owongolera makompyuta ndi mawonedwe akulu aku China, mawonekedwe ake ndi okongola komanso osalala.Makiyi a kiyibodi omwe angopangidwa kumene ndi osavuta komanso othamanga, ndipo mabwalo ndi zigawo zomwe zimatumizidwa kunja, kotero kuti chidacho chimagwira ntchito mokhazikika komanso chodalirika.

Kachitidwe mawonekedwe

Ⅰ, Kuphatikizana kwakukulu, kulondola kwambiri, ntchito zambiri,

1, makiyi onse a microcomputer, 5.7 inchi (320 * 240) chiwonetsero chachikulu cha LCD mu Chitchaina ndi Chingerezi, Chitchaina ndi Chingelezi chikhoza kusinthidwa mwaufulu, kukwaniritsa zofunikira zamagulu osiyanasiyana a anthu, kukambirana kwa makina a anthu, kosavuta kugwira ntchito. .

2, Microcomputer control hydrogen flame chowunikira kuti mukwaniritse ntchito yoyatsira, yanzeru kwambiri.Watsopano Integrated digito zamagetsi dera, mkulu kulamulira mwatsatanetsatane, khola ndi odalirika ntchito, mpaka 0.01 ℃ kutentha kulondola molondola.

3, ntchito yoteteza gasi, tetezani mzati ndi dziwe lotenthetsera matenthedwe, chowunikira ma elekitironi.

Imakhala ndi ntchito yodzizindikiritsa poyambira, yomwe imathandizira ogwiritsa ntchito kudziwa mwachangu chifukwa chake ndi malo a kulephera kwa chida, ntchito ya stopwatch (yosavuta kuyeza koyenda), kulephera kwa mphamvu yosungira ndi chitetezo, ntchito yotsutsana ndi kusintha kwamphamvu, kulumikizana kwa data pa intaneti. ndi ntchito yowongolera kutali.Ntchito yoteteza kutentha kwambiri ndiyotsimikizika

Chidacho sichinawonongeke ndipo chili ndi dongosolo la kukumbukira deta lomwe silifuna kukonzanso kulikonse.

Ⅱ、 jakisoni dongosolo lapadera kapangidwe, akhoza kukhala malire kudziwika malire

1. Mapangidwe apadera a doko la jakisoni kuti athetse tsankho la jekeseni;Ntchito yolipirira mizati iwiri sikungothetsa kusuntha kwa mzere woyambira chifukwa cha kutentha komwe kumakonzedwa, komanso kumachepetsa mphamvu ya phokoso lakumbuyo kuti mupeze malire ozindikira.

2, Yokhala ndi gawo lodzaza, dongosolo la jakisoni la capillary shunt/non-shunt (lokhala ndi ntchito yoyeretsa diaphragm)

3, Optional automatic/manual gasi jekeseni wanjira zisanu ndi imodzi, jekeseni wapamutu, jekeseni ya kutentha, chosinthira methane, jekeseni wodziwikiratu.

Ⅲ、Kutentha kokonzedwa, kuwongolera kutentha kwa ng'anjo, kukhazikika kwachangu

1, Eight-order liniya kutentha anakonza, pambuyo khomo ntchito photoelectric lophimba contactless kapangidwe, odalirika ndi cholimba, wanzeru pambuyo dongosolo khomo stepless variable mpweya voliyumu, kufupikitsa pulogalamu pambuyo kuwuka / kutsika kwa chojambulira dongosolo khola bwino bwino nthawi, kuzindikira kwenikweni ntchito yapafupi ya kutentha kwa chipinda, kuwongolera kutentha kwa ± 0.01 ℃, kumakwaniritsa zofunikira pakuwunika kosiyanasiyana.

2, Voliyumu yaikulu ya bokosi ndime, wanzeru kumbuyo khomo dongosolo stepless variable mpweya voliyumu mkati ndi kunja, kufupikitsa pulogalamu pambuyo kukweza / kuziziritsa chowunikira dongosolo khola bwino bwino nthawi;Kutentha ng'anjo dongosolo: yozungulira kutentha +5 ℃ ~ 420 ℃

3, The kutchinjiriza zotsatira ndi bwino: mzati bokosi, vaporization, kudziwika ndi madigiri 300, bokosi kunja ndi chivundikiro pamwamba ndi zosakwana madigiri 40, kusintha mlingo experimental, kuonetsetsa chitetezo cha wosuta.

4, kamangidwe kapadera ka chipinda cha vaporization, voliyumu yaying'ono yakufa;Chalk m'malo: jekeseni jekeseni, liner, polarizer, wosonkhanitsa, nozzle akhoza m'malo ndi dzanja limodzi;Kusintha kwakukulu kwa thupi: mzere wodzaza, capillary sampler ndi chowunikira zitha kuchotsedwa kwathunthu ndi wrench, kukonza kosavuta.

Kumverera kwakukulu, chowunikira chokhazikika kwambiri, kukwaniritsa zosowa za ziwembu zosiyanasiyana

Hydrogen flame ionization detector (FID), thermal conductivity cell detector (TCD), electron Capture detector (ECD),

Flame Photometric detector (FPD), Nitrogen ndi Phosphorus detector (NPD)

Mitundu yonse ya zowunikira zimatha kuyendetsedwa paokha kutentha, chojambulira chamoto wa hydrogen ndi chosavuta kugawa ndikuyika, chosavuta kuyeretsa kapena m'malo mwa nozzle.
