Ethylene glycol inorongwa sei zvichienderana nehuwandu hwealdehyde?
2026-02-26
Muindasitiri yemakemikari, Ethylene Glycol inogonawo kuverengerwa zvichienderana nehuwandu hwealdehydes. Hunhu hwakaderera hwealdehyde (kazhinji 50 mg/kg iri giredhi rakaderera.
Kubva pakuona kwemavara, mamakisi anotsanangurwa uchishandisa chikero chemavara chePt-Co:
Ethylene Glycol Premium Giredhi: ≤ 5 Hazen units
Giredhi Repakati: 5–15 Hazen units
Giredhi Rakaderera: > 15 Hazen units (inogona kukanganisa mashandiro ekushandisa muzvirongwa zvinotarisa chitarisiko)
Kuwanda kwesimbi chimwe chiratidzo chikuru chekuchena uye njodzi yekuora kwemidziyo:
Ethylene Glycol High Grade: Giredhi Yepakati: 0.1–1 mg/kg
Giredhi Rakaderera: > 1 mg/kg (inogona kukurumidzisa ngura yemidziyo)
Ethylene Glycol Density pa20°C inoshandiswawo pakuyera:
Giredhi Repamusoro: 1.113–1.115 g/cm³
Ethylene Glycol Giredhi Rokutanga: 1.112–1.116 g/cm³
Giredhi Rakakodzera: 1.111–1.117 g/cm³

Zibo Anhao Chemical Co., Ltd. inyanzvi yekugadzira uye inopa ethylene glycol (EG) yemhando yepamusoro, ine ruzivo rwakakura muindasitiri yemakemikari. Zvigadzirwa zvedu zve ethylene glycol zvinogadzirwa uchishandisa maitiro ekugadzira epamusoro uye masisitimu ekudzora mhando akasimba, zvichiona kuti zvinoenderana ne standard yenyika GB/T 4649-2018 yemagiredhi epamusoro, ekirasi yekutanga, uye akakodzera. Iine hunhu hwakanaka hwakadai sekusagadzikana kwakaderera, ngura shoma, uye kusasanganiswa kwakakwana nemvura uye organic solvents, EG yedu inoshandiswa zvakanyanya mukugadzira polyester fiber, antifreeze solutions, solvents, uye kugadzira makemikari emaindasitiri.
Tichitsigirwa nezvigadzirwa zvedu uye nzira dzedu dzekutengesa dzakagadzikana, tinopa zvigadzirwa zvakavimbika, zvinoenderana uye mhinduro dzakagadziriswa kune vatengi vepasi rose. Semubatsiri akavimbika muchikamu chemakemikari, Zibo Anhao Chemical yakazvipira kupa ethylene glycol yepamusoro uye kutsigira budiriro inoenderera mberi yemabhizinesi evatengi vedu pasi rese.
