Ethylene Glycol: Tsofa ni Akɛtsuɔ Yiŋtoi Srɔtoi kɛ Nɔ ni Haa Fɛ̃i Haa
Nitsumɔhei Wuji
Yɛ tsɔnei ahe nitsumɔhe lɛ, ethylene glycol ji nɔ titri ni akɛwoɔ tsɔnei ni haa fɛ̃i baa lɛ amli. Ehaa nu lɛ mli fɛ̃i lɛ baa shi, ni ehaaa nu ni mli ejɔ lɛ afee ais yɛ hulutsoo be ni baa shi mli, ni ewoɔ he ni nu lɛ fɛ̃ɔ lɛ nɔ, ni ehaaa tsɔne lɛ mli adɔ fe nine. Akɛ antifreeze ni akɛ ethylene glycol fee lɛ tsuɔ nii babaoo yɛ tsɔnei, lɔlei, kɛ nitsumɔhei nibii amli fɛ̃i mli koni tsɔne lɛ atsu nii jogbaŋŋ yɛ hulutsoo be ni mli wa waa mli. Kɛfata he lɛ, ethylene glycol lɛ yɛ hulutsoo ni hi jogbaŋŋ kɛ hulutsoo ni tsiɔ nii anaa, ni baanyɛ aha hulutsoo gbɛjianɔtoi lɛ asɛɛ atsɛ.
Yɛ tsofafeemɔ nitsumɔhe lɛ, ethylene glycol ji nɔ ko ni he hiaa waa kɛha nibii ni wala yɔɔ mli lɛ afeemɔ. Akɛtsuɔ nii kɛfeɔ polyethylene terephthalate (PET), ni ji nɔ titri ni akɛfeɔ polyester tsɔji, ŋmeii, kɛ plastic tsɛnsii. Abaanyɛ akɛ ethylene glycol hu afee nibii srɔtoi ni wala yɔɔ mli, tamɔ ethylene glycol ethers, esters, kɛ amines, ni akɛtsuɔ nii babaoo yɛ tsofai ni akɛwoɔ mli, nibii ni akɛwoɔ mli, niŋmaatsei, kɛ ilɛkrɔnik tsofai amli.
Yɛ tsofafeemɔ nitsumɔhe lɛ, akɛ ethylene glycol tsuɔ nii akɛ nɔ ni akɛwoɔ tsofa mli kɛ nɔ ni akɛwoɔ mli. Ebaanyɛ efo tsofai amli nibii komɛi amli, ni eha tsofai lɛ ahi shi jogbaŋŋ ni amɛmli atsɔ mli. Kɛfata he lɛ, abaanyɛ akɛ ethylene glycol afee tsofafeemɔ mli nibii komɛi, tamɔ ethylene glycol ethers kɛ esters, ni yɔɔ nitsumɔi ni he hiaa waa yɛ tsofafeemɔ mli.
Yɛ atadefeemɔ nitsumɔhe lɛ, akɛ ethylene glycol tsuɔ nii kɛfeɔ polyester tsɔji. Ale polyester fibers akɛ amɛhe wa waa, amɛnyɛŋ amɛfite, ni amɛhiɛ amɛhe jogbaŋŋ, ni akɛtsuɔ nii babaoo yɛ atadei, shia atadei, kɛ nitsumɔhei atadei amli. Ethylene glycol tsuɔ gbɛfaŋnɔ titri ko he nii yɛ tsɔne ni akɛwoɔ tsɔne mli lɛ feemɔ mli kɛtsɔ terephthalic acid ni ekɛfeɔ tsɔne ni akɛwoɔ tsɔne mli lɛ nɔ, ni no haa tsɔne ni akɛwoɔ tsɔne mli lɛ feɔ tsɔne ni hi jogbaŋŋ.
Yɛ tsɔnei ahe nitsumɔhe lɛ, akɛ ethylene glycol tsuɔ nii akɛ nɔ ni haa nu mli jɔɔ kɛ nɔ ni haa nu mli jɔɔ. Abaanyɛ akɛtsu nii ni akɛtsumɔ tsɔne mli nibii ahe, ni ajie muji ni yɔɔ nɔ kɛ nibii ni eshwɛ lɛ. Kɛfata he lɛ, akɛ ethylene glycol-based coolants tsuɔ nii yɛ tsɔnei ni haa hulu tsoɔ lɛ amli koni hulutsoo lɛ ahi shi shiŋŋ yɛ be mli ni tsɔnei ni akɛwoɔ tsɔne mli lɛ tsuɔ nii waa lɛ.
Yɛ bɔ ni akɛtsuɔ nii yɛ gbɛi srɔtoi anɔ lɛ fɛɛ sɛɛ lɛ, ethylene glycol lɛ ji tsofa fɔŋ, ni ekɛ nitsumɔ kɛ etoohe biɔ shweshweeshwefeemɔ he gbɛjianɔtoo ni mli wa.
