    IIPROPATI ZEKHEMICAL

    I-Tetrahydrofuran (THF) lulwelo olungenambala, oluguquguqukayo olunevumba le-ethereal okanye i-acetone efana ne-acetone kwaye iyaxubeka emanzini kunye nezinyibiliki ezininzi eziphilayo.Ukugcinwa ixesha elide ekudibaneni nomoya kwaye xa kungekho nto yokulwa ne-antioxidant kunokubangela ukuba i-THF ibole ibe yiperoxides eqhumayo.

    I-Tetrahydrofuran isetyenziselwa ukwenziwa kweepolymers kunye nezolimo, amayeza, kunye neekhemikhali zentengiso.Imisebenzi yokuvelisa iqhele ukwenzeka kwiinkqubo ezivaliweyo okanye phantsi kolawulo lobunjineli olunqanda ukuvezwa kwabasebenzi kunye nokukhululwa kokusingqongileyo.I-THF ikwasetyenziswa njengesinyibilikisi (umzekelo, ukufakwa kombhobho) okunokubangela utyhileko olubalulekileyo xa isetyenziswa kwiindawo ezivalelekileyo ngaphandle kokungena komoya okwaneleyo.Nangona i-THF ikhona ngokwendalo kwivumba lekofu, ii-ertyisi eziphekiweyo, kunye nenkukhu ephekiweyo, ukuvezwa kwendalo akulindelwanga ukuba kubangele ingozi enkulu.

    I-Butylene oxide isetyenziswa njenge-fumigant kunye nengxubevange kunye nezinye iikhompawundi.Isetyenziselwa ukuzinzisa isibaso malunga nokwakheka kombala kunye nodaka.

    I-Tetrahydrofuran isetyenziswe njenge-solvent forresins, i-vinyls, kunye neepolymers eziphezulu;njengeGrignardreaction medium ye-organometallic, kunye ne-metal hydride reactions;kunye nakwi-synthesis ye-succinic acid kunye ne-butyrolactone.

    I-Tetrahydrofuran isetyenziselwa ikakhulu (i-80%) ukwenza i-polytetramethylene ether glycol, i-polymer esisiseko esetyenziswa ngokuyinhloko ekwenzeni i-elastomeric fibers (umzekelo, i-spandex) kunye ne-polyurethane kunye ne-polyester elastomers (umzekelo, isikhumba sokwenziwa, amavili e-skateboard).Intsalela (20%) isetyenziswa kusetyenziso lwezinyibilikisi (umzekelo, iisamente zemibhobho, izinto zokuncamathelisa, ii-inki zokuprinta, kunye neteyiphu yemagnethi) nanjengento enyibilikayo kwimichiza kunye nokudibanisa amayeza.

    INDLELA YOKUTHENGA KUTHI

    I-Chemwin inokubonelela ngoluhlu olubanzi lwee-hydrocarbons ezininzi kunye nezinyibilikisi zeekhemikhali kubathengi bamashishini.Ngaphambi koko, nceda ufunde olu lwazi lulandelayo olusisiseko malunga nokwenza ishishini nathi: 

    1. Ukhuseleko

    Ukhuseleko yeyona nto iphambili kuthi.Ukongeza ekunikeni abathengi ngolwazi malunga nokusetyenziswa ngokukhuselekileyo nokuhambelana nokusingqongileyo kweemveliso zethu, sikwazimisele ekuqinisekiseni ukuba imingcipheko yokhuseleko lwabasebenzi kunye neekontraka ziyathotywa ukuya kutsho kubuncinane obufanelekileyo nobunokwenzeka.Ngoko ke, sifuna ukuba umthengi aqinisekise ukuba imigangatho efanelekileyo yokukhutshwa kunye nokugcinwa kwemigangatho yokhuseleko idibene ngaphambi kokunikezelwa kwethu (nceda ubhekisele kwisihlomelo se-HSSE kwimimiselo jikelele kunye neemeko zokuthengisa ngezantsi).Iingcali zethu zeHSSE zinokubonelela ngesikhokelo kule migangatho.

    2. Indlela yokuhambisa

    Abathengi banokuodola kwaye bahambise iimveliso kwi-chemwin, okanye banokufumana iimveliso kwisityalo sethu sokuvelisa.Iindlela ezikhoyo zothutho ziquka iilori, uloliwe okanye uthutho lweendlela ezininzi (kuyasebenza iimeko ezahlukileyo).

    Kwimeko yeemfuno zabathengi, sinokucacisa iimfuno zeenqanawa okanye iitanki kwaye sisebenzise imigangatho ekhethekileyo yokhuseleko / ukuhlaziya kunye neemfuno.

    3. Ubuncinci bobungakanani bomyalelo

    Ukuba uthenga iimveliso kwiwebhusayithi yethu, ubungakanani obuncinci bomyalelo ziitoni ezingama-30.

    4.Intlawulo

    Indlela yokuhlawula eqhelekileyo itsalwa ngokuthe ngqo kwiintsuku ezingama-30 kwi-invoyisi.

    5. Amaxwebhu okuhanjiswa

    La maxwebhu alandelayo anikwe ngokuziswa ngakunye:

    · Ibhili yokuLading, i-CMR Waybill okanye olunye uxwebhu olufanelekileyo lwezothutho

    · Isatifikethi sokuHlalutya okanye ukuThobela (ukuba siyafuneka)

    · Amaxwebhu anxulumene neHSSE ngokuhambelana nemigaqo

    · Amaxwebhu ezinto eziqhelekileyo ngokuhambelana nemigaqo (ukuba kuyafuneka)

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
