Nhanganyaya

Jira rakanyungudutswa rine hunhu hwehudiki pore saizi, yakakwira porosity uye yakakwirira kusefa kunyatsoita, uye ndiyo yakakosha zvinhu zvekugadzira mask.Ichi chiridzwa chinoreva GB/T 30923-2014 plastiki Polypropylene (PP) Melt-blown Special Material, yakakodzera polypropylene seyakanyanya mbishi zvinhu, ine di-tert-butyl peroxide (DTBP) sechinhu chinoderedza, yakagadziridzwa polypropylene yakanyunguduka. special material.

Nzira musimboti

Sample inonyungudutswa kana kuzvimba mu toluene solvent ine huwandu hunozivikanwa hwen-hexane seyemukati mwero.Huwandu hwakakodzera hwemhinduro hwakatorwa ne microsampler uye yakananga jekiseni mugasi chromatograph.Mune mamwe mamiriro ezvinhu, gasi chromatographic analysis yakaitwa.DTBP yakasara yakatemwa neyemukati mwero nzira.

Main midziyo uye reagents

1) Gasi chromatograph, Capillary column inlet, FID detector,

2) Ongorora chiyero

3) Capillary column: AT.624 30m*0.32mm*1.8μm,

4) Chromatographic workstation software,

5) N-hexane, chromatographic yakachena;

GC-7890 Gasi chromatograph inotora microcomputer control system uye Chinese hombe chidzitiro chiratidziro, chitarisiko chakanyanya kunaka uye chakatsetseka.Makiyi ekhibhodi achangogadzirwa akareruka uye anokurumidza, uye maseketi ari kunze kwenyika zvikamu, saka kuita kwechiridzwa kwakagadzikana uye kwakavimbika.

Performance feature

Ⅰ、Kubatanidzwa kwedunhu repamusoro, kunyatsojeka, kushanda-zhinji,

1, All-microcomputer kiyi oparesheni, 5.7 inch (320 * 240) hombe LCD kuratidzwa muChinese neChirungu, Chinese neChirungu kuratidzwa kunogona kuchinjika zvakasununguka, kuzadzisa zvinodiwa nemapoka akasiyana evanhu, man-machine dialogue, nyore kushanda. .

2, Microcomputer inodzora hydrogen murazvo detector kuti iwane otomatiki yekubatidza basa, yakanyanya kungwara.Nyowani yakabatanidzwa yedhijitari yemagetsi dunhu, yakakwirira kudzora kurongeka, yakagadzikana uye yakavimbika kuita, kusvika 0.01 ℃ tembiricha yekudzora kurongeka.

3, Gasi kuchengetedza basa, chengetedza mbiru uye yekupisa conductivity dziva, erekitironi kutora detector.

Iine basa rekuzviongorora pachayo pakutanga, iyo inoita kuti vashandisi vakurumidze kuziva chikonzero uye nzvimbo yekukundikana kwechiridzwa, stopwatch basa (yakanaka kuyerera kuyerwa), simba rekutadza kuchengetedza uye kuchengetedza basa, anti-simba mutation kupindira basa, network data network. uye remote control function.Iyo overtemperature yekudzivirira basa inovimbiswa

Iyo chiridzwa haina kukuvadzwa uye ine data memory system iyo isingade rese reset.

Ⅱ、Injection system yakasarudzika dhizaini, inogona kuve yakaderera yekuona muganho

1. Yakasarudzika jekiseni pachiteshi dhizaini kugadzirisa kusarura kwejekiseni;Iyo kaviri column compensation function haingogadzirise base-line drift yakakonzerwa netembiricha yakarongwa, asi zvakare inobvisa pesvedzero yeruzha rwekumashure kuti uwane yakaderera yekuona muganho.

2, Iine packed column, capillary shunt/non-shunt jekiseni system (ine diaphragm yekuchenesa basa)

3, Optional otomatiki/manual gasi nzira nhanhatu injector, headspace injector, thermal resolution injector, methane converter, otomatiki jekiseni.

Ⅲ、Tembiricha yakarongedzerwa, yakanyatso kudzora tembiricha yevira, kugadzikana nekukurumidza

1, Eight-yakarongeka tembiricha yakarongedzerwa, mushure memusuwo uchishandisa photoelectric switch contactless dhizaini, yakavimbika uye inogara, yakangwara mushure memusuwo system isina nhanho inosiyana mhepo vhoriyamu, kupfupisa chirongwa mushure mekusimuka / kudonha kweiyo detector system yakagadzikana chiyero nguva, nyatso ziva. iyo iri padyo nekamuri tembiricha kushanda, tembiricha kutonga kurongeka kwe ± 0.01 ℃, inosangana nezvinodiwa zvehuwandu hwekuongorora.

2, Huru vhoriyamu yebhokisi bhokisi, yakangwara yekumashure dhizaini system isina nhanho inochinja mhepo mukati nekunze, kupfupisa chirongwa mushure mekusimudza / kutonhora detector system yakagadzikana chiyero nguva;Heating choto system: ambient tembiricha +5 ℃ ~ 420 ℃

3, The insulation effect iri nani: iyo column box, vaporization, kuonekwa i300 degrees, bhokisi rekunze uye chivharo chepamusoro chiri pasi pemadhigirii makumi mana, kuvandudza chiyero chekuedza, kuve nechokwadi chekuchengetedzwa kwemushandisi.

4, Yakasarudzika dhizaini ye vaporization kamuri, diki vhoriyamu yakafa;Zvishandiso zvinotsiva: jekiseni padhi, liner, polarizer, muunganidzi, nozzle inogona kutsiviwa neruoko rumwe;Kutsiviwa kwemuviri mukuru: koramu yekuzadza, capillary sampler uye detector inogona kubviswa zvachose nechipanera chete, kugadzirisa kuri nyore.

High senitivity, high stability detector, inosangana nezvinodiwa zvezvirongwa zvakasiyana

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

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

Ese marudzi edhijitari anogona kuzvimiririra kudzorwa tembiricha, hydrogen murazvo detector iri nyore kuparadzanisa uye kuisa, nyore kuchenesa kana kutsiva muromo.
