Mashandisirwo eBisphenol A (BPA)

Bisphenol A (BPA) chinhu chakakosha pakugadzira ma polycarbonates, epoxy resins, uye ma polyester anodzivirira kupisa kwakanyanya. Inoshandiswawo se PVC stabilizer, plastic antioxidant, UV absorber, fungicide, nezvimwewo.
Semusanganiswa unoshanduka-shanduka, BPA inoshandiswa zvakanyanya mukugadzira epoxy resins, polycarbonates, polyester resins, polyphenylene ether resins, uye polysulfone resins. Pamusoro pezvo, inoshanda se stabilizer ye polyvinyl chloride (PVC), antioxidant mupurasitiki, UV absorber, agricultural fungicide, uye anti-aging agent murabha.
Inoshandiswawo se antioxidant uye plasticizer mumapendi neinki. Mukugadzirwa kwezvinhu zvakasikwa, BPA inoshanda sechinhu chakakosha pakugadzira epoxy ne polycarbonate resins, uye inoshandiswa zvakanyanya sechinhu chakakosha chekugadzira zvinhu zvine mamorekuru akawanda, pamwe nekudzivirira kukwegura, plasticizers, uye fungicides dzekurima.

1. Kuvimbika Kwekutumira & Kushanda Kwakanaka
Zvinhu Zvikuru:
Nzvimbo dzekuchengetedza zvinhu dziri muchiteshi chengarava cheQingdao, Tianjin, neLongkou dzine vanhu vanodarika chiuru
matani emari aripo
68% yemirairo inotumirwa mukati memazuva gumi nemashanu; mirairo yekukurumidzira inopihwa pekutanga kuburikidza nekutakura zvinhu nekukurumidza
chiteshi (kukurumidzisa kwe30%)
2. Kutevedzera Hunhu & Mutemo
Zvitupa:
Zvitupa zvitatu pasi pe REACH, ISO 9001, uye FMQS zvinodiwa
Zvinoenderana nemitemo yepasi rose yehutsanana; chiyero chekubudirira kwe100% chekubvisa mitero yemutero
Zvinhu zvinopinzwa kubva kuRussia
3. Hurongwa hwekuchengetedzwa kwekutengeserana
Mhinduro dzekubhadhara:
Mashoko anochinjika: LC (kuona/nguva), TT (20% advance + 80% pakutumira)
Zvirongwa zvehunyanzvi: 90-day LC yemisika yeSouth America; Middle East: 30%
dhipoziti + muripo weBL
Kugadzirisa gakava: nzira yekupindura kwemaawa makumi manomwe nemaviri yekusawirirana kwakabatana nehurongwa
4. Zvivakwa zveAgile Supply Chain
Network yeZvinhu Zvakasiyana-siyana:
Kutakura nendege: Kutumirwa kwemazuva matatu kwepropionic acid kuThailand
Kutakurwa kwechitima: Nzira yakatsaurirwa yecalcium formate kuenda kuRussia kuburikidza neEurasian corridors
Mhinduro dzeISO TANK: Kutumira makemikari emvura zvakananga (semuenzaniso, propionic acid ku
India)
Kugadzirisa Kurongedza:
Tekinoroji yeFlexitank: Kuderedzwa kwemutengo we ethylene glycol ne12% (zvichienzaniswa nedhiramu rechinyakare)
kurongedza)
Calcium formate/Sodium Hydrosulfide yemhando yekuvaka: Mabhegi ePP akarukwa asingapindi hunyoro e25kg
5. Maitiro Ekuderedza Njodzi
Kuonekwa Kwemagumo:
Kutevera GPS panguva chaiyo yekutumira zvinhu mumidziyo
Mabasa ekuongorora evamwe vanhu pazviteshi zvekuenda (semuenzaniso, kutumirwa kweacetic acid kuSouth Africa)
Vimbiso yeKutengesa Mushure meKutengesa:
Gadziriso yemhando yemazuva makumi matatu ine sarudzo dzekutsiva/dzokudzoserwa mari
Zvishandiso zvekutarisa tembiricha zvemahara zvekutumira magaba e reefer

Maitiro eBisphenol a bpa Acid-Catalyzed
Mukuita kweacid-catalyzed, ma catalysts anowanzova sulfuric acid, hydrochloric acid, kana hydrogen chloride gasi.
Maitiro ekushandisa sulfuric acid se catalyst ane kuyerera kuri nyore, anogadzirwa muketero imwe chete, anoshanda nguva nenguva, haadi kuti phenol idzoke, uye ane mari shoma. Zvisinei, ine zvakawanda zvinobva muzvigadzirwa zvayo, mhando yebisphenol A bpa isina kunaka, kushandiswa kwakanyanya, marara akawanda matatu (gasi rakasviba, mvura yakasviba, uye marara akaoma), ngura yakanyanya mumidziyo, uye goho shoma. Nzira yesulfuric acid yakabviswa mhiri kwemakungwa muma1960.
Nzira inoshandisa hydrochloric acid kana hydrogen chloride gasi se catalyst inonzi hydrochloric acid method. Nzira yehydrochloric acid ine nzira yakakura yekugadzira uye inogona kugadzirwa nguva nenguva kana nguva dzose. Kushandiswa kwezvinhu zvakagadziriswa uye mainjiniya eruzhinji kwakaderera, uye chigadzirwa chinogona kusvika pamhando yepamusoro mushure mekunatswa, iyo inoshandiswa mukugadzira polycarbonate. Nekuda kwekuora kwakasimba kwehydrochloric acid, zvinodiwa zvemidziyo, mapaipi, uye zvishandiso zvakakwirira, saka mari yekudyara nekugadzirisa yakakwira. Kufanana nenzira yesulfuric acid, marara matatu aya akakomba. Maitiro ehydrochloric acid ndiyo yaive nzira huru yekugadzira pasi rose muma1970 nema1980.
