Application

3,4-oxydicialine cas 2657-87-8 inoshandiswa mune pi firimu, yakakwirira kupisa inodzivirira yekufambisa midziyo yekugadzira, nezvimwe

1. Dyes uye pigment: Inoshandiswa seyepakati mune synthesis yemakadhi uye pigment, kunyanya mune maindasitiri ekudhinda uye ekudhinda.

2..

3. Zvinodhaka: Inogona kushandiswa sechinhu chakapenda mune synthesis yemishonga yezvinodhaka.

4. Chemical kutsvakazve: 3,4-dipherl ether inoshandiswa mukutsvagisa kwemakemikari akasiyana-siyana uye kusimudzira, kusanganisira nekutsvagisa kwezvinonhuwira uye nhaka yavo.

5..

Nezvekufambisa

* Tinogona kugovera mhando dzakasiyana dzekutakura zvichienderana nevatengi zvevatengi.
* Kana huwandu hushoma, tinogona kutumira nemhepo kana dzenyika dzenyika, dzakadai saFedEx, DHL, tnt, tnt, ems uye dzakasiyana siyana dzekutakura nzvimbo dzinokosha.
* Kana huwandu hukuru, tinogona kutumira gungwa kuGungwa kugadza.
* Kunze kwezvo, isu tinokwanisa kupawo mabasa akakosha zvichienderana nezvinodiwa nevatengi uye zvigadzirwa 'zvivakwa.

Kubhadhara

* Tinogona kupa huwandu hwenosarudza dzekubhadhara kune vatengi vedu.
* Kana mari yacho ine mwero, vatengi vanobhadhara nePayPal, Western Union, Alibaba, uye mamwe masevhisi akafanana.

Chengetedza

Yakachengetwa mune yakaoma uye yakachengetedzwa imba yekuchengetera.

1. Mudziyo: Chengetedza mumudziyo weAirtight kudzivirira kusvibiswa uye kunyorova kunyorera.

2. Nzvimbo: Chengetedza mudziyo mune inotonhorera, yakaoma, nzvimbo ine mvura kure kure neyakajeka zuva uye kupisa masosi.

3. Kupisa

5. Label: zvakajeka midziyo nemidziyo yemakemikari, nzeve dzengozi, uye risiti rekutambira.

3,4,4-oxydialililiine ine njodzi here?

Ehe, 3,4-dipherl ether inoonekwa seine ngozi. Iyo inogadziriswa sechinhu chine ngozi nekuda kwezvakakwanisa kuita pane hutano. Heano dzimwe pfungwa dzinokosha nezve njodzi dzayo:

1. Cheturality: 3,4-dipherl ether zvinogona kukonzera kukuvadza kana yakamedzwa, inhay, kana yakanyudzwa kuburikidza neganda. Inogona kunge ichitsamwisa paganda, maziso, uye turakiti rekufema.

2. Carcinogenicity: Zvimwe zvidzidzo zvakaratidza kuti zvinonhuhwirira emagetsi (kusanganisira 3,4-dipherl ether) zvinogona kunge zviri carcinogenic. Inokurudzirwa kubata nekuchenjerera uye kuderedza kuratidzwa.

Nyevero panguva yekufambisa

1. Kurongedza:

Shandisa midziyo yakakodzera inoenderana ne3,4-dipherl ether. Ita kuti midziyo yemigadziri yakanamirwa nesimba kuti udzivise kusunungurwa kana kupaza.
Zviripachena zvemanyorero midziyo nemakemikari zita, hazard chiratidzo uye chero ruzivo rwakakodzera rekuchengetedza.

2. Zvekufambisa mitemo:
Inotevedzera zvemunharaunda, yenyika uye zvepasi zvenyika zvekutakura zvinhu zvine njodzi. Izvi zvinogona kusanganisira kutevedzera nyika dzemubatanidzwa (UN) mirau uye iyo nyika yepasi rose inowirirana system yezvinhu zvine njodzi (GHS) kuiswa uye zvinodiwa zvekushandisa.

3. Kuchengetedza Kwemunhu (PPP):
Ita shuwa kuti vashandi vevashandi vekutakurwa kwe3,4-dipherl ether vanopfeka michina yekudzivirira yakakwana yemunhu, senge magurovhosi, goggles uye zvipfeko zvinodzivirira, kuti uderedze kuratidzwa.

4. Emergency maitiro:
Vane emergency emergency maitiro munzvimbo mune imwe nzvimbo yekudonha kana tsaona panguva yekufambisa. Izvi zvinosanganisira kuve nekupaza kits uye yekutanga rubatsiro rwekubhadhara kugadzirira.

5. Ngwarira kusapindirana:
Ita shuwa kuti 3,4-dipherl ether haina kutakurwa pamwe neisingawirirani zvinhu (senge yakasimba oxidants kana acids) kudzivirira kusagadzikana kuita.

6. Tembiricha kutonga:
Kana zvichidikanwa, tarisa uye kudzora tembiricha panguva yekufambisa kuti udzivise kusvibiswa kweiyo compound.

7. Kudzidziswa:
Ita shuwa kuti vashandi vese vakabatanidzwa mukubata uye kufambisa kwe3,4-dipherl ether vanogamuchira kudzidziswa kwakakodzera mune zvine njodzi zvekubata uye mhinduro yekukurumidzira.
