Igama lemveliso:I-Terephthalic acid
Imo yemolekyuli:C8H6O4
Inombolo yeCAS:100-21-0
Ulwakhiwo lwemolekyuli yemveliso:
Iasidi yeTerephthalic ayinyibiliki kakuhle emanzini nakwiziselo ezinxilisayo, ngenxa yoko kude kube malunga no-1970 uninzi lwe asidi ekrwada ye-terephthalic yaguqulelwa kwi-dimethyl ester ukuze ihlanjululwe. I-sublimates xa ishushu.
umgubo omhlophe
I-Terephthalic acid (TPA) yikhemikhali ye-tonnage ephezulu, esetyenziswa ngokubanzi kwimveliso yezinto zokwenziwa, ngokukodwa i-polyester fibers (i-poly-(ethylene terephthalate)).
I-Terephthalic acid yi-benzenepolycarboxylic acid eneempawu ezichasene nokopha.
I-1,4-benzenedicarboxylic acid isetyenziselwa ukuveliswa kwe-poly (ethylene terephthalate). Kwakhona ukuveliswa kwe-plasticizer dioctyl phthalate (DOTP) kunye ne-polyester plasticized agents. I-1,4-benzenedicarboxylic acid kunye ne-polyhydric alcohols ine-condensation reaction withd iethylene glycol, i-triethylene glycol, i-glycerol, i-propylene glycol, i-butylene glycol, njl njl ukulungiswa kweplastiki ye-polyester.
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)
