Tic ma pire tek
Bisphenol A tye gin ma pire tek ma ki tiyo kwede i yubu polymers ma tiyo maber ki jami ma ki tiyo kwede i gang tic, ki jami ma lubo ni:
Polycarbonate (PC) Plastic Production
Ma calo gin ma ki tiyo kwede me yubu PC plastic, BPA miyo twero me yubu jami ma pe twero tur, ma pe twero lyeto calo jami ma ki tiyo kwede i mac (laptops, smartphones), jami ma ki tiyo kwede i motoka (gin ma umu mac, jami ma i iye), ki jami ma ki keto iye cam (ma ki keto pi gwoko kwo i kabedo mapol).
Epoxy Resin Synthesis
Ki tiiyo kwede me yubu epoxy resins pi umu (me labolle, umu ma iye, umu ma gengo buru), adhesives (jami ma mako gedo ma tek pi dege ki gedo), ki jami ma gengo mac (circuit boards, transformer windings).
Tic mukene me yubu jami
Gin ma ki tiyo kwede me yubu polyether polyols (ma ki tiyo kwede i polyurethane foams).
Gin ma ki medo i plasticizers, flame retardants, ki UV stabilizers pi jami ma ki lwongo ni polymer.
Gin ma tye i kin jami ma ki yubu ki jami ma pat pat (me labolle, jami ma gengo two, jami ma miyo rangi).
rwom me rwom
Jami wa ma ki lwongo ni Bisphenol A rwate ki cik me wilobo ki gwoko kuc, ki lanyut me gwoko leng ki goro ma calo ma lubo ni:
| Index | rwom me tic (ma rwate) | Gin ma ki lwongo ni Reagent Grade (High Purity) |
|---|---|---|
| Lengo (HPLC) | ≥ 99.5% | ≥ 99.8% |
| Kit ma yamo tye kwede | ≤ 0.1% | ≤ 0.05% |
| Gin ma tye iye | ≤ 0.01% | ≤ 0.005% |

Jami ma ki yubu ma opore tye pi gin ma mite i gang tic (me labolle, jami ma pe leng pi yubu jami ma twero mako cam).
Cik me gwoko ki tic kwede
Me neno ni jami ni tye maber ki tic maber, lub jami ma miite me gwoko ki tic kwede:
Kit me gwoko jami
Lyeto: Gwok i kabedo ma ngiic, ma otwo i 15-25 °C; gwokke ki lyeto matek (>30 °C) onyo ngiico (
Lero: Tii ki jami ma pe nen maber (me labolle, cupa ma ki yubu ki gilaci macol, HDPE ma ki gwoko ki UV) me gengo balo pa UV.
Yamo: Gwok yamo ma rwate
Jami ma mite me umu
Gwok jami ma ki keto iye ni ki umu maber ingee tic kwede me gengo pii ki balo ne. Kur tic ki yoo me umu pi kare manok (me labolle, bongo ma ki yubu ki plastik) ma twero kelo two.
Gwoko kwo
Ruk jami ma gwoko komi (PPE): Gin ma umu buru, cing ma gengo jami ma kelo two, ki jami ma gwoko komi ka itye ka tic kwede (tutwale pi jami ma ki yubu ki buru ma ki lwongo ni powder/granular forms).
Yamo: nen ni yamo mol maber i ka gwoko ki ka gwoko jami me gengo buru onyo yamo ma mol.
Kit me tic ki jami ma opoto: Yub jami ma opoto ki jami ma kwanyo pii (lobo ma ki lwongo ni diatomaceous earth, activated carbon); bolo yugi ma lubu cik ma kwako jami ma kelo peko.
Lubu cik
Cik ma ki keto i wilobo: Lubu cik me EU REACH Regulation (Annex XVII) ma gengo BPA i kom jami ma ki camo (me labolle, ki gengo i cupa me cam pa lutino).
US FDA: rwate ki cik pa FDA pi tic ki BPA i kom jami ma ki keto i kom cam ki jami ma ki yubu ki plastik (21 CFR 175.300).
Cik me China: Lubu cik me GB 4806.6 (cik me gwoko kwo pa jami ma ki yubu ki jami ma ki lwongo ni plastic resins).
Kit me keto ne ki kare me gwoko ne
Kit me keto jami i bok:
Kit me tic: 25 kg HDPE plastic bags (ki inner polyethylene liners) onyo 500 kg fiber drums (ma ki umu ki aluminum foil).
Gin ma ki lwongo ni Reagent Grade: 1 kg me amber glass bottles (ki umu ki Teflon-lined caps).
Kare me gwoko: Dwe 24 cake i nino dwe ma ki yubu kwede (ka ki gwoko ma lubu cik ma malo ni, ma pe ki yabo).
