Tic ma pire tek
Bisphenol A ubedo piny ma pire tek ikind yiku pa polymers maber man piny mi tic, ku tic ma e:
Polycarbonate (PC) Plastic Production
Calu piny ma pire tek ma jutiyo kudu pi PC plastic, BPA konyowa ni yubu piny ma copo tur ungo, man ma copo lyeth ungo calu ot pa jam tic (laptops, smartphones), jam tic mi mutukari (jamb lwoko mac, panel mi iye), man piny ma mako cam (ma juketho pi gwoko kwo i kabedu mapol).
Epoxy Resin Synthesis
Jutiyo kudu pi yubu epoxy resins pi umo (e.g., umo ma iye, umu ma juku nyai), adhesives (adhesives ma tek pi aerospace man construction), man piny ma juku mac (circuit boards, transformer windings).
Tic mange mi yiku piny
Piny ma jutiyo kudu pi polyether polyols (ma jutiyo kudu i polyurethane foams).
Piny ma ju medo i plasticizers, flame retardants, man UV stabilizers pi polymer materials.
Piny ma pire tek ikind yubu kemikol ma tung tung (e.g., antioxidants, dyestuffs).
Ber pa piny
Piny mwa ma Bisphenol A lubu cik mi ng'om zoo man cik mi gwoko leng pa piny, ku lanyuth pa leng man leng ma e:
| Index | Kite mi tic (ma rwinyo) | Reagent Grade (High Purity) |
|---|---|---|
| Lengo (HPLC) | ≥ 99.5% | ≥ 99.8% |
| Piny ma pii iye | ≤ 0.1% | ≤ 0.05% |
| Ash Content | ≤ 0.01% | ≤ 0.005% |
| Piny ma pek (Pb, Cd, Hg) | ≤ 10 ppm | ≤ 1 ppm |
| Phenol Residue | ≤ 0.2% | ≤ 0.05% |
Lembe ma juyike utiye pi yeny moko mi tic (e.g., low-impurity grades pi yubu piny ma mako cam).
Cik mi gwoko piny man tic kugi
Mi neno nia piny peri utiye maber man etiye maber, lub cik maeni mi gwoko man mi tiyo kudu:
Kite mi kano piny
Lieth: Gwok kama ngic, man muthwo i 15-25 °C; jwigo lyethu ma tek (>30 °C) nyo ngico (
Lero: Ti ku piny ma nen ungo (calu, agulu macol, HDPE plastic drums ku UV protection) mi juku nyoth pa UV.
Piny ma ngic: Gwoko piny ma ngic
Piny ma mitere pi ketho cing ikum
Keth piny ma ijeni maber ingey tic kudu pi gwoko pii man nyayu piny ma rac. Kur tic ku yore mi cego piny ma rii pi kare manok (calu, plastic wrap) ma copo nyayu two.
Gwoko kwo
Ruk piny mi gwoko kwo peri (PPE): Jam gwoko kum, gloves ma jugwoko ku kemikol, man goggles mi gwoko kum ka itiyo ku piny (mandha ne pi piny ma buru/granular).
Yamu: Nenu nia yamu wok maber i kabedu mi kano piny man kama jutiyo kudu kara kud unyai buru man yamo.
Gwoko piny ma upoto: Yik piny ma upoto ku piny ma nyayu pii (diatomaceous earth, activated carbon); jwigo yugi nimakere ku cik mi kabedo peri ikum kemikol ma rac.
Lubu cik
Cik mi ng'om zoo: Lubu cik pa EU REACH Regulation (Annex XVII) ma juketho iwi BPA i piny ma mako cam (e.g., ma juketho i cupa mi cam pa awiya).
US FDA: Urombo ku cik pa FDA pi tic ku BPA i jamb tiyo ku cam man plastik (21 CFR 175.300).
Cik pa China: Lubu cik pa GB 4806.6 (cik mi gwoko leng pa plastik ma mako cam).
Kethu piny man kwo pa piny
Yore mi kethu piny:
Kite mi tic: 25 kg HDPE plastic bags (ku polyethylene liners) nyo 500 kg fiber drums (ma juketho ku aluminum foil).
Reagent Grade: 1 kg amber glass bottles (sealed with Teflon-lined caps).
kwo pa piny: dwi 24 nicaku i ceng ma juyubu kudu (ka jugwoko nimakere ku cik ma malu, ma juyabu ngo).
