    Isicelo

    I-1.gamma-Valerolactone inekhono eliqinile lokusabela, futhi ingasetshenziswa njengesincibilikisi kanye nezinhlobonhlobo zamakhemikhali ahlobene.
    I-2.gamma-Valerolactone isetshenziswa njenge-lubricant, i-plasticizer, i-gelling agent yama-nonionic surfactants, isigaba se-lactone se-additive petroli eholayo.
    I-3.gamma-Valerolactone iphinde isetshenziselwe ukudaya i-cellulose ester kanye ne-synthetic fiber dyeing.

    Iphakheji

    1 kg/isikhwama noma 25 kg/isigubhu noma 50 kg/isigubhu noma ngokwezidingo zamakhasimende.

     

    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

    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.

    Isitoreji

    1. Gcina endaweni epholile, nengena umoya.
    2. Gcina kude nomlilo nemithombo yokushisa.
    3. Gwema ukukhanya kwelanga okuqondile.
    4. Gcina isitsha sivalwe ngokuqinile.
    5. Kufanele igcinwe ngokuhlukana nama-oxidants, ama-ejenti anciphisayo, nama-acids, futhi igweme ukugcinwa okuxubile.
    6. Ifakwe izinhlobo ezihambisanayo namanani ezinto zokucisha umlilo.
    7. Indawo yokugcina kufanele ifakwe izinto zokwelashwa eziphuthumayo ezivuzayo kanye nezinto ezifanele zokugcina.

    Ukuzinza

    1. Gwema ukuthintana nama-oxidants aqinile, ama-ejenti anciphisa amandla, nama-asidi aqinile. Gqoka izingubo zokuzivikela uma usetshenziswa.
    2. Ikhona emaqabunga kagwayi aphekwe ngomkhuhlane kanye namaqabunga kagwayi we-burley.
