Inoshandiswa se resin yekurapa yepakati uye yekugadzira 2-Furaldehyde [98-01-1]

Zita remakemikari: 2-Furaldehyde

Mazwi akafanana: 2-Formyl furan; 2-furanaldehyde; 2-furancarbonal; 2-furancarboxaldehyde; 2-furfural; 2-furylmethanal; alpha-Furfuraldehyde; Furfuraldehyde; Pyromucic aldehyde;

Kurema kwemasero: C5H4O2

Chitarisiko: Mvura isina ruvara kusvika kutsvuku - brown ine mafuta ine hwema hwema hwema hwema

Kugadzikana: 1. Haiparadzi simbi, inogona kuchengetwa mumidziyo yesimbi, simbi isina kusimba, mhangura kana aruminiyamu. Inoshanduka zvishoma nezvishoma kuva brown mumhepo kana muchiedza, saka inofanira kuvanzwa kubva kuchiedza uye kuzadzwa negasi risina simba kuti ichengetwe yakavharwa. Mushure mekunge furfural yaiswa muokisijeni, mhepo, kabhoni dioxide uye nitrogen kwemazuva makumi mana, huwandu hwema oxide (resinous) akaumbwa hwaive 1.7%, 0.3%, 0.1% uye 0.05%, zvichiteerana. Kuwedzera p-hydroxydiphenylamine, diphenylamine, cadmium iodide, hydroquinone, phloroglucinol kana β-naphthol ku furfural, kuwedzera 0.1% kunogona kudzivirira oxidation zvinobudirira. Kuwedzera 0.001% ~ 0.1% N-phenyl-substituted urea, thiourea kana naphthylamine ku furfural kunogona kudzivirira kuumbwa kwe resin kana yapiswa pa60 ~ 170℃.

2. Hunhu hwemakemikari: furfural ine hunhu hwealdehyde. Semuenzaniso, musanganiswa wekuwedzera unogona kugadzirwa nesodium bisulfite, iyo inosanganiswa kuita furanoic acid uye inoderedzwa kuita furfuryl alcohol. Furfuryl alcohol ne furfuran formic acid zvakagadzirwa neCannizzaro reaction mu concentrated potassium hydroxide solution. Inosangana ne potassium cyanide kuti igadzire furoin. Inosangana neammonia kuti igadzire furfuramide, inobatana neamine kuti igadzire Schiff base. Furfural inopiswa kusvika 350~400℃ ne sodium lime, kana nickel kana zinc oxide ne chromium, vanadium pentaoxide se catalyst inopiswa kusvika 200℃, uye furan inoshandurwa. Kana furfural yakanatswa ikaiswa, nekuda kwekushanda kweokisijeni mumhepo, maitiro akaomarara akadai sekuora uye polymerization anoitika, zvichiita kuti ruvara ruve rwakasviba. Kupisa kana chiedza zvinogona kukurumidzisa kuora kwayo, polymerization reaction.

3. Kugadzikana Kugadzikana

4. Mushonga wakasimba we oxidizing, hwaro hwakasimba

5. Dzivisa kupisa, chiedza, nemhepo

6. Kugadzirisa zvinhu (polymerization) kunokanganisa kuparadzanisa zvinhu (polymerization)

1.Kuchena kwakanyanya 99.0% min

2.Shandisa zvakasiyana-siyana zvekunaka.

3. Tine chitupa che ISO 9001, ISO 14001 uye ISO22000, Tinewo chitupa cheHACCP, tine chitupa cheHalal uye kosher chechigadzirwa ichi.

5. Tine mukana mukuru, saka, tinowanzova nenguva yekukurumidza.

6. Tinogona kupa 10g-50g yemuenzaniso wemahara wekuyedzwa kwenyu murabhoritari. Tinowanzo tumira sampuli iyi nemakambani ekunze akadai seDHL kana Fedex. Inokurumidza uye iri nyore.

1. Kurongedza kwemuenzaniso i20g/30g/50g pabhodhoro.

2. Chikafu chidiki ichi chinorema 1kg /5kg /10 kg pabhodhoro.

3.25 kg padhiramu (dhiramu repurasitiki remhando yechikafu, risina purasitiki, gwaro retifiketi rebato rechitatu)

Kurongedza kunogonawo kugadziriswa zvichienderana nezvinodiwa nevatengi
