Ubujamo bokubulungwa kwe-bisphenol A kufanele bujikeleze iinhloso eziqakathekileko "zokuvimbela ukuwohloka, ukuqinisekisa ukuphepha, nokubalekela umthelela wemvelo".

Ukusetjenziswa kwe-Bisphenol A (BPA)

I-Bisphenol A (BPA) yinto eqakathekileko yokwenza ama-polycarbonates, ama-epoxy resins, kanye nama-polyesters ajamelana nokutjhisa okuphezulu. Isetjenziswa njenge-PVC stabilizer, i-antioxidant yeplastiki, i-UV absorber, i-fungicide, njll.
Njengekhompawundi ehlukileko, i-BPA isetjenziswa khulu ekukhiqizeni ama-epoxy resins, ama-polycarbonates, ama-polyester resins, ama-polyphenylene ether resins, kanye nama-polysulfone resins. Phezu kwalokho, isebenza njengesiqinisi se-polyvinyl chloride (PVC), i-antioxidant emapulasitiki, i-UV absorber, i-agricultural fungicide, kanye ne-anti-aging ejenti erabha.
Ibuye isetjenziswe njenge-antioxidant kanye neplastiki emapendeni nasema-inkini. Ekuhlanganisweni kwezinto eziphilako, i-BPA isebenza njengesithako esiqakathekileko sokwenza ama-epoxy nama-polycarbonate resin, begodu isetjenziswa khulu njengesisetjenziswa esiqakathekileko sokwenza amakhompawundi wokwenziwa ngama-molecular aphezulu, kanye nama-ejenti wokulwisana nokuguga, ama-plasticizer, kanye nama-fungicides wezokulima.

1. Ukuthembeka kokulethwa nokusebenza kuhle
Iimfanelo eziqakathekileko:
Iindawo zokugcina izinto eziqakathekileko e-Qingdao, Tianjin, kanye ne-Longkou port warehouses ezine-1,000+
amathani wamamethrikhi wesitoko atholakalako
68% wama-oda alethwe kungakapheli amalanga ali-15; ama-oda aphuthumako abekwe phambili ngokusebenzisa ukuthuthwa okurhabako
isiteshi (30% ukusheshisa)
2. Ikhwalithi nokuthobela imithetho
Izitifiketi:
Iqinisekiswe kathathu ngaphasi kwamazinga we-REACH, ISO 9001, kanye ne-FMQS
Ukuthobela imithetho yokuhlanzeka yephasi loke; 100% izinga lokuphumelela lokuvunyelwa kwamasiko
Ukungeniswa kwe-Russia
3. Uhlaka lokuvikeleka kokuthengiselana
Iinsombululo zokubhadela:
Amathemu atjhugulukako: LC (ukubona/ithemu), TT (20% ngaphambilini + 80% ngemva kokuthunyelwa)
Iinhlelo ezikhethekileko: i-LC yamalanga ama-90 yeemakethe zeSewula Melika; I-Middle East: 30%
idiphozithi + ukubhadelwa kwe-BL
Ukurarulula iingxabano: iphrothokholi yokuphendula yama-awa ama-72 malungana neengxabano ezihlobene ne-oda
4. Ingqalasizinda ye-Agile Supply Chain
Inethiwekhi yokuPhatha ngeendlela ezinengi:
Ukuthunyelwa ngemoya: ukulethwa kwamalanga ama-3 kwe-propionic acid eya e-Thailand
Iinthuthi zesitimela: Indlela ye-calcium formate eya e-Russia ngeendlela ze-Eurasian
Iinsombululo ze-ISO TANK: Ukuthunyelwa kwamakhemikhali amanzi (isib., i-propionic acid ukuya
I-India)
Ukwenza ngcono ukuphakheja:
Ithekhnoloji ye-Flexitank: ukwehliswa kweendleko eziyi-12% ze-ethylene glycol (ngokuqathaniswa nesigubhu sendabuko
ukupakisha)

5. Iindlela zokunciphisa ubungozi
Ukubonakala ukusuka ekupheleni ukuya ekupheleni:
Ukulandelela kwe-GPS kwesikhathi sangempela kokuthunyelwa kweenkhonteyina
Imisebenzi yokuhlola yomuntu wesithathu emachwebeni lapho iya khona (isib., ukuthunyelwa kwe-acetic acid eSewula Afrika)
Isiqinisekiso sangemva kokuthengisa:
Isiqinisekiso sekhwalithi samalanga ama-30 esineendlela zokubuyisela/ukubuyiselwa imali
Iinsetjenziswa zokugada amazinga womtjhiso wokuthunyelwa kwamakhonteyina we-reefer

Ukusabela okukhulu
I-Bisphenol a BPA synthesis reaction yenziwa yi-molecule eyodwa ye-acetone kanye nama-molecule amabili we-phenol ngaphasi kwemibandela ye-acidic catalytic. Ukusabela kuba yi-exothermic, begodu amanzi ngumkhiqizo omkhulu. Ukusabela kusebenzisa i-DOWEX cation exchange resin njenge-catalyst. I-catalyst le itholakala ngemva kokwelatjhwa nge-promotha begodu inokukhetha okufaneleko kwe-Bisphenol a BPA synthesis. I-phenol/acetone ratio ngesikhathi sokusabela siphezulu khulu, begodu ukusabela kwenziwa nge-adiabatic reactor.
Ukusabela kuphinde kukhiqize ukungcola okulandelako:
I-OP-BPA
I-Trisphenol
I-Dihydroxydihydroanthracene
Iinhlanganisela ze-Dianin
Utjwala obungumama bubuyiselwa emuva ukulinganisa inani lokungcola ukuqinisekisa bona ukusabela okukhulu kukhiqiza i-PP-BPA. Isitjalo sifakwe ama-reactor amabili ahlangeneko, enye yawo evamise ukusetjenziselwa ukulinda nofana ukuvuselela. Lokha umsebenzi we-catalyst uphansi khulu, i-reactor eyodwa iyasuswa emgqeni wokukhiqiza, i-catalyst endala iyasuswa, begodu ngaphambi kobana ihlanganiswe godu emgqeni wokukhiqiza, i-catalyst etja ephathwe nge-promotha iyalayishwa.
