I-Dimethyl etheringxube yemvelo eyigesi engenambala nengenaphunga evuthayo ngaphansi kwezimo ezijwayelekile, enefomula yamakhemikhali ethi C2H6O.
Ukuxuba nomoya kungakha izingxube eziqhumayo, ezijwayele ukusha nokuqhuma lapho kuthinta ukushisa, izinhlansi, amalangabi, noma ama-oxidants.Ama-peroxide anobungozi obunamandla bokuqhuma angenziwa ngokuthintana nomoya noma ngaphansi kwezimo zokukhanya, ngokuminyana okuphezulu kunomoya.Angasakazekela ebangeni elide ezindaweni eziphansi futhi akhele lapho ehlangana nomthombo womlilo.Uma uhlangabezana nokushisa okuphezulu, ukucindezela ngaphakathi kwesiqukathi kuyanda, okubeka ingozi yokuqhekeka nokuqhuma.

Gcina endaweni epholile nengena umoya.Gwema izinhlansi nemithombo yokushisa.Izinga lokushisa endaweni yokugcina impahla akufanele lidlule 30 ℃.Kufanele igcinwe ngokuhlukana nama-oxidants, ama-asidi, nama-halogen, futhi akufanele ihlanganiswe ukuze igcinwe.Ukusebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya.Vimbela ukusetshenziswa kwezinto eziwumshini namathuluzi ajwayele ukuba nezinhlansi.Indawo yokugcina kufanele ifakwe izinto zokusabela ezimeni eziphuthumayo lapho kuvuza.
Lapho uthutha amasilinda ensimbi, kuyadingeka ukugqoka isigqoko sokuphepha ku-cylinder.Amasilinda ensimbi ngokuvamile abekwa ayisicaba, futhi umlomo webhodlela kufanele ubheke ohlangothini olufanayo futhi ungaweli;Ubude akufanele budlule ucingo oluyisivikelo lwemoto, futhi amaphedi okhuni angunxantathu kufanele asetshenziselwe ukuyivikela ukuvimbela ukugingqika.Ngesikhathi sokuthutha, izimoto zokuhamba kufanele zifakwe izinhlobo ezihambisanayo kanye nenani lempahla yokucima umlilo.Ipayipi le-exhaust lemoto ephethe le nto kufanele ifakwe idivayisi evimbela ilangabi, futhi akuvunyelwe ukusebenzisa imishini namathuluzi ajwayele ukuba nezinhlansi zokulayisha nokukhipha.Akuvunyelwe ngokuphelele ukuxuba nokuthutha nama-oxidants, ama-acids, ama-halogen, amakhemikhali adliwayo, njll. Ukuthutha kufanele kwenziwe ekuseni nakusihlwa ehlobo ukuvimbela ukukhanya kwelanga okuqondile.Ngesikhathi sokuma, gwema izinhlansi nemithombo yokushisa.Ngesikhathi sokuthutha emgwaqweni, kuyadingeka ukulandela umzila onqunyiwe futhi ume ezindaweni zokuhlala nezinabantu abaningi.Akuvunyelwe ukushelela ngesikhathi sokuthutha ngololiwe.
I-Dimethyl ether, njengezinto ezisetshenziswayo eziyisisekelo zamakhemikhali ephilayo ezivelayo, inezinto eziningi ezisetshenziswayo eziyingqayizivele embonini yezemithi, uphethiloli, yezibulala-zinambuzane nezinye zamakhemikhali ngenxa yokucindezelwa kwayo okuhle kakhulu, ukufingqa, kanye nezici zokufakwa kwegesi.I-dimethyl ether ehlanzekile kakhulu ingangena esikhundleni se-Freon njengesifutho se-aerosol nesiqandisi, inciphisa ukungcoliswa kwendawo ezungezile yomoya kanye nokulimala kongqimba lwe-ozone.Ngenxa yokuncibilika kahle kwamanzi kanye nokuncibilika kwamafutha, ububanzi bokusebenzisa kwayo buphakeme kakhulu kunamakhemikhali e-petroleum njenge-propane ne-butane.Ukushintsha i-methanol njengento entsha yokukhiqizwa kwe-formaldehyde kunganciphisa kakhulu izindleko zokukhiqizwa kwe-formaldehyde futhi kubonise ukuphakama kwayo ezitshalweni ezinkulu ze-formaldehyde.Njengegesi kaphethiloli ovamile, izinkomba zayo zokusebenza ezifana nokugcinwa nezokuthutha, ukuphepha kokusha, inani lekhalori legesi elixutshwe ngaphambili, nezinga lokushisa elingokomqondo liphakeme kunelegesi ye-petroleum ewuketshezi.Ingasetshenziswa njengegesi ephezulu yokushefa yegesi yamapayipi asemadolobheni kanye nengxube yegesi ye-petroleum eliquefied.Iphinde ibe uphethiloli olungele izinjini zikadizili, futhi uma iqhathaniswa nezimoto eziphehlwa nge-methanol, ayikho inkinga ngokuqala okubandayo kwezimoto.I-Dimethyl ether futhi ingenye yezinto zokusetshenziswa eziyinhloko zokukhiqizwa kwama-olefin ane-carbon ephansi esikhathini esizayo.
I-Chemwin ingahlinzeka ngenqwaba yama-hydrocarbon amaningi nezincibilikisi zamakhemikhali kumakhasimende ezimboni.Ngaphambi kwalokho, sicela ufunde ulwazi olulandelayo oluyisisekelo mayelana nokwenza ibhizinisi nathi:
1. Ezokuphepha
Ukuphepha kuyinto ehamba phambili yethu.Ngaphezu kokunikeza amakhasimende ulwazi mayelana nokusetshenziswa okuphephile nokunobungani kwemvelo kwemikhiqizo yethu, siphinde sizibophezele ekuqinisekiseni ukuthi ubungozi bokuphepha kwabasebenzi nosonkontileka buncishiswa bube buncane obunengqondo nobunokwenzeka.Ngakho-ke, sidinga ukuthi ikhasimende liqinisekise ukuthi izindinganiso ezifanele zokuphepha zokuthulula nokugcina impahla ziyahlangatshezwa ngaphambi kokulethwa kwethu (sicela ubheke isithasiselo se-HSSE emigomeni nemibandela yokuthengisa ngezansi).Ochwepheshe bethu be-HSSE banganikeza isiqondiso kulawa mazinga.
2. Indlela yokulethwa
Amakhasimende anga-oda futhi alethe imikhiqizo evela ku-chemwin, noma angathola imikhiqizo evela embonini yethu yokukhiqiza.Izindlela zokuthutha ezitholakalayo zifaka phakathi iloli, ujantshi noma ezokuthutha ezinezinhlobo eziningi (kuyasebenza izimo ezihlukene).
Endabeni yezidingo zekhasimende, singacacisa izidingo zezikebhe noma amathangi futhi sisebenzise amazinga akhethekile okuphepha/wokubuyekeza kanye nezimfuneko.
3. Inani elincane le-oda
Uma uthenga imikhiqizo kuwebhusayithi yethu, inani elincane le-oda amathani angama-30.
4.Inkokhelo
Indlela yokukhokha ejwayelekile idonswa ngokuqondile zingakapheli izinsuku ezingu-30 ukusuka ku-invoyisi.
5. Amadokhumenti okulethwa
Amadokhumenti alandelayo anikezwa ngokudiliva ngakunye:
· I-Bill of Lading, i-CMR Waybill noma enye incwadi yezokuthutha efanele
· Isitifiketi Sokuhlaziya noma Ukuvumelana (uma sidingeka)
· Imibhalo ehlobene ne-HSSE ngokuhambisana nemithethonqubo
· Imibhalo yeCustoms ngokuhambisana nemithethonqubo (uma kudingeka)
