    Isicelo

    I-1.Njenge-solvent evamile, i-Tetrahydrofuran isetshenziswa kabanzi ekugqokeni okungaphezulu, izigqoko zokuzivikela, ama-inks, ama-extractants kanye nokwelashwa kwendawo yesikhumba sokwenziwa.

    I-2.I-Tetrahydrofuran iyinto ebalulekile yokukhiqiza i-PTMEG kanye ne-solvent eyinhloko yemboni yezemithi.

    Impahla

    I-Tetrahydrofuran iwuketshezi olungenambala olusobala olunephunga le-ether. Ixubene namanzi, utshwala, i-acetone, i-benzene, i-ester, i-ether ne-hydrocarbon.

    Iphakheji

    1 kg/isikhwama noma 25 kg/isigubhu noma 200 kg/isigubhu noma ngokwezidingo zamakhasimende.

    iphakheji-uketshezi-1

    Mayelana Nezokuthutha

    * Singahlinzeka ngezinhlobo ezahlukene zezokuthutha ngokwezidingo zamakhasimende.

    * Uma inani lilincane, singathumela ngezindiza noma ngezithunywa zamazwe ngamazwe, njenge-FedEx, DHL, TNT, EMS kanye nemigqa ehlukahlukene yezokuthutha zamazwe ngamazwe.

    * Uma inani likhulu, singahamba ngomkhumbi siye echwebeni elimisiwe.

    * Ngaphandle kwalokho, singaphinde sinikeze izinsizakalo ezikhethekile ngokuya ngezidingo zamakhasimende kanye nezakhiwo zemikhiqizo.

    Ezokuthutha

    Inkokhelo

    * Singahlinzeka ngezindlela zokukhokha ezihlukahlukene ngokukhetha kwamakhasimende.

    * Uma inani lilincane, amakhasimende ngokuvamile akhokha nge-PayPal, i-Western union, i-Alibaba, njll.

    * Uma inani likhulu, amakhasimende ngokuvamile akhokha nge-T/T, L/C lapho ebona, i-Alibaba, njll.

    * Ngaphandle kwalokho, amakhasimende amaningi ngokwengeziwe azosebenzisa i-Alipay noma i-WeChat akhokhe ukuze enze inkokhelo.

    inkokhelo

    Ukuphatha kanye Nesitoreji

    1. Izinyathelo zokuphepha zokuphatha ngendlela ephephile

    Gwema ukuthinta isikhumba namehlo. Gwema ukuhogela umhwamuko noma inkungu.

    Ziqhelelanise nemithombo yokuthungela - Akubhenywa. Thatha izinyathelo zokuvimbela ukwakheka kwe-electrostatic

    khokhisa.

    2. Imibandela yokugcina okuphephile, okuhlanganisa noma yikuphi ukungahambisani

    Gcina endaweni epholile. Gcina isitsha sivalwe ngokuqinile endaweni eyomile futhi enomoya omuhle. Iziqukathi okuyizoevuliwe kufanele ivalwe kabusha ngokucophelela futhi igcinwe iqondile ukuze kuvinjelwe ukuvuza.

    Izinsalela ezomile ziyaqhuma. Gcina ngaphansi kwegesi engasebenzi. Hlola ukwakheka kwe-peroxide ngezikhathi ezithile nangaphambiukucwiliswa emanzini.

    Isigaba sesitoreji (TRGS 510): Uketshezi oluvuthayo

    Izinyathelo zokukhishwa ngengozi

    1. Izinyathelo zokuzivikela, izinto zokuzivikela kanye nezinqubo eziphuthumayo

    Sebenzisa izinto zokuzivikela. Gwema umhwamuko wokuphefumula, inkungu noma igesi. Qinisekisa ukuthi kungena umoya owanele.

    Susa yonke imithombo yokuthungela. Thuthukisa abasebenzi ezindaweni eziphephile. Qaphela imihwamuko enqwabelanayoyakha ukugxila kokuqhuma. Umhwamuko unganqwabelana ezindaweni eziphansi.

    2. Izinyathelo zokuphepha kwemvelo

    Vimbela ukuvuza okwengeziwe noma ukuchitheka uma kuphephile ukwenza kanjalo. Ungavumeli umkhiqizo ungene emiseleni. 

    3. Izindlela nezinto zokwakha zokunqanda nokuhlanza

    Iqukethe ukuchitheka, bese iqoqa ngesicoci esivikelwe ngogesi noma ngokuxubha futhifaka esitsheni ukuze ulahlwe ngokwemithetho yendawo
