（China）GC-7890 Ditert-butyl Peroxide Residue Detector
Nsalu yosungunuka imakhala ndi ma pore ang'onoang'ono, ma porosity ambiri komanso kusefa bwino kwambiri, ndipo ndiye chinthu chofunikira kwambiri popanga chigoba. Chida ichi chikutanthauza zinthu zapadera za GB/T 30923-2014 pulasitiki ya Polypropylene (PP) Melt-blown, zoyenera polypropylene ngati zinthu zazikulu zopangira, ndi di-tert-butyl peroxide (DTBP) ngati chochepetsera, komanso zinthu zapadera za polypropylene zosungunuka.
Chitsanzocho chimasungunuka kapena kutupa mu toluene solvent yokhala ndi n-hexane yodziwika bwino monga muyezo wamkati. Kuchuluka koyenera kwa yankho kunatengedwa ndi microsampler ndikulowetsedwa mwachindunji mu gasi chromatograph. Pazifukwa zina, kusanthula kwa gasi chromatographic kunachitika. Zotsalira za DTBP zidatsimikiziridwa pogwiritsa ntchito njira yamkati.
1) Chromatograph ya gasi, Cholowera cha m'mizere ya capillary, chowunikira cha FID,
2) Unikani bwino
3) Mzere wa capillary: AT.624 30m*0.32mm*1.8μm,
4) Mapulogalamu a Chromatographic workstation,
5) N-hexane, yopanda chromatographic;
6) Di-tert-butyl peroxide, yopanda poizoni;
7) Toluene, yoyera kusanthula.
Chromatograph ya Gas ya GC-7890 imagwiritsa ntchito makina owongolera makompyuta ang'onoang'ono ndi chiwonetsero chachikulu cha ku China, mawonekedwe ake ndi okongola komanso osalala. Makiyi a kiyibodi omwe apangidwa kumene ndi osavuta komanso achangu, ndipo ma circuits ndi zida zomwe zimatumizidwa kunja, kotero magwiridwe antchito a chida ndi okhazikika komanso odalirika.
Ⅰ. Kuphatikiza kwakukulu kwa dera, kulondola kwambiri, ntchito zambiri
1. Kugwira ntchito kwa makiyi a microcomputer onse, chiwonetsero chachikulu cha LCD cha mainchesi 5.7 (320 * 240) mu Chitchaina ndi Chingerezi, chiwonetsero cha Chitchaina ndi Chingerezi chikhoza kusinthidwa momasuka, kuti chikwaniritse zofunikira za magulu osiyanasiyana a anthu, kukambirana kwa makina a anthu, komanso kugwiritsa ntchito kosavuta.
2. Chowunikira moto wa haidrojeni chowongolera ma microcomputer kuti chikwaniritse ntchito yoyatsira yokha, chanzeru kwambiri. Dongosolo latsopano lamagetsi la digito lophatikizidwa, kulondola kwambiri, magwiridwe antchito okhazikika komanso odalirika, kulondola kowongolera kutentha mpaka 0.01℃.
3. Ntchito yoteteza mpweya, kuteteza mzati ndi dziwe loyendetsera kutentha, chowunikira chojambulira ma elekitironi.
Ili ndi ntchito yodziyesa yokha akayamba kugwiritsa ntchito, zomwe zimathandiza ogwiritsa ntchito kudziwa mwachangu chomwe chayambitsa ndi malo a kulephera kwa chipangizocho, ntchito yoyimitsa (kuyeza kuyenda kosavuta), ntchito yosungira ndi kuteteza kulephera kwa magetsi, ntchito yotsutsana ndi kusintha kwa magetsi, kulumikizana kwa deta ya netiweki, ndi ntchito yowongolera kutali. Ntchito yoteteza kutentha kwambiri imatsimikizika
Chidacho sichinawonongeke ndipo chili ndi makina osungira deta omwe safuna kubwezeretsanso deta nthawi iliyonse.
Ⅱ.Dongosolo la jakisoni lapadera, likhoza kukhala lotsika kwambiri pozindikira
1. Kapangidwe kapadera ka doko lojambulira kuti athetse kusiyana kwa jakisoni; Ntchito yolipirira mizere iwiri sikuti imangothetsa kusuntha kwa mzere wapansi komwe kumachitika chifukwa cha kutentha komwe kwakonzedwa, komanso imachotsa mphamvu ya phokoso lakumbuyo kuti mupeze malire ocheperako ozindikira.
2. Ndi mzere wodzaza, dongosolo lojambulira la capillary shunt/non-shunt (lokhala ndi ntchito yoyeretsa diaphragm)
3. Chojambulira mpweya chodzipangira chokha/chogwiritsa ntchito pamanja cha njira zisanu ndi chimodzi, chojambulira cha mutu, chojambulira kutentha, chosinthira methane, chojambulira chodzipangira chokha.
Ⅲ, Kutentha kokonzedwa, kulamulira kutentha kwa ng'anjo molondola, kukhazikika mwachangu
1. Kutentha kolunjika kwa mizere isanu ndi itatu komwe kumakonzedwa, pambuyo pa chitseko pogwiritsa ntchito mawonekedwe a photoelectric switch osakhudza, kodalirika komanso kolimba, kwanzeru pambuyo pa chitseko, kopanda kusuntha, kopanda kusintha kwa mpweya, kufupikitsa pulogalamuyo pambuyo pa kukwera/kutsika kwa nthawi yokhazikika ya detector system, kuzindikira kutentha kwa chipinda, kulondola kwa kuwongolera kutentha kwa ± 0.01℃, kukwaniritsa zofunikira zosiyanasiyana.
2. Kuchuluka kwakukulu kwa bokosi la mzati, dongosolo lanzeru la chitseko chakumbuyo lopanda kusuntha mpweya wosinthasintha wolowa ndi kutuluka, kufupikitsa pulogalamuyo mutakweza/kuziziritsa dongosolo la chowunikira nthawi yokhazikika; Dongosolo la kutentha kwa uvuni: kutentha kozungulira +5℃ ~ 420℃.
3. Mphamvu ya kutchinjiriza ndi yabwino: bokosi la mzati, nthunzi, kuzindikira ndi madigiri 300, bokosi lakunja ndi chivundikiro chapamwamba ndi zosakwana madigiri 40, zimawonjezera liwiro loyesera, kuti zitsimikizire chitetezo cha wogwiritsa ntchito.
4. Kapangidwe kapadera ka chipinda chotenthetsera mpweya, chocheperako chopanda mpweya; Kubwezeretsa zowonjezera: jekeseni wa jekeseni, choyikapo, polarizer, chosonkhanitsa, nozzle zitha kusinthidwa ndi dzanja limodzi; Kubwezeretsa thupi lalikulu: mzati wodzaza, choyezera cha capillary ndi chowunikira zitha kuchotsedwa kwathunthu ndi wrench yokha, kukonza kosavuta.
Chowunikira kwambiri, chowunikira kukhazikika kwambiri, chimakwaniritsa zosowa za mapulani osiyanasiyana
Chowunikira kuwala kwa hydrogen flame (FID), chowunikira kutentha kwa maselo oyendetsera kutentha (TCD), chowunikira kugwidwa kwa ma electron (ECD),
Chowunikira cha Photometric cha malawi (FPD), chowunikira cha nayitrogeni ndi phosphorous (NPD)
Mitundu yonse ya zozindikira imatha kuyendetsedwa kutentha payokha, chowunikira moto wa hydrogen ndi chosavuta kusokoneza ndikuyika, chosavuta kuyeretsa kapena kusintha nozzle.
Doko lojambulira
Pali ma doko osiyanasiyana ojambulira: jakisoni wodzazidwa ndi mizati, jakisoni wa shunt/non-shunt capillary
