Tic pa Bisphenol A (BPA)

Bisphenol A (BPA) ubedo piny ma pire tek pi yubu polycarbonates, epoxy resins, man polyesters ma tek tek. Jutiyo kudu bende calu PVC stabilizer, plastic antioxidant, UV absorber, fungicide, man mukende mapol.
Calu piny ma tiyo ku yore madwong, BPA jutiyo kudu lee iyubu epoxy resins, polycarbonates, polyester resins, polyphenylene ether resins, man polysulfone resins. Mi medo, etiyo calu piny ma jwigo polyvinyl chloride (PVC), piny ma jwigo lyethu i plastik, piny ma jwigo UV, piny ma jwigo lum, man piny ma jwigo dongo i rubber.
Man de jutiyu kudu calu piny ma gwoko kum man ma weko piny doko tek i rangi man ink. I tic mi yubu piny ma kwo, BPA timo tic calu piny ma pire tek pi yiku epoxy man polycarbonate resins, man jutiyo kudu lee calu piny ma pire tek pi yiku piny ma dongo dongo, man bende i piny ma jwigo dongo, plasticizers, man fungicides mi poto.

4. Agile Supply Chain Infrastructure
Multimodal Logistics Network:
Tero piny ku yamu: cwalo pi nindu adek pi cwalo propionic acid i Thailand
Wotho ku gari: Yore ma juyike pi calcium formate ni Russia nikadhu kud i Eurasian corridors
ISO TANK solutions: Cwalu piny ma pii (e.g., propionic acid ni
India)
Kethu piny maber:
Flexitank technology: 12% dwoko piny wel piny pi ethylene glycol (vs. traditional drum
packaging)
Construction-grade calcium formate/Sodium Hydrosulfide: Moisture-resistant 25kg woven PP bags
5. Yore mi jwigo peko
Nen pa piny ni kajik:

One-step synthesis: Yore eni jutiyo kudu lee kawoni. Etie ku rwom acel mi epichlorohydrin, bisphenol A BPA, man pii ma tek, niwacu, rwom mi yabo man cego ring. Piny moko pa epichlorohydrin man bisphenol A BPA juyike i lyethu pa 70~90°C pi kare moko, i ngeye lyethu pa pii judwoko piny ni 40~50°C, man wel moku pa 30~40% NaOH jumedo. I ngei ma timo ne umediri pi kare manok, epichlorohydrin ma timo ngo tic ne judwoku kud i vacuum distillation. Ka dong dwoko piny eca uthum, lyethu pa pii ma jucwalo judwoko piny ni piny 50°C, man wel moku pa 15% NaOH jumedo iwi pii.
