Mawu ofanana mu Chingerezi

Ethylene glycol, 1, 2-ethylenediol, EG mwachidule

makhalidwe a mankhwala

Fomula ya mankhwala: (CH2OH)2 Kulemera kwa molekyulu: 62.068 CAS: 107-21-1 EINECS: 203-473-3 [5 Malo osungunuka: -12.9 ℃ Malo owira: 197.3 ℃

Chiyambi cha malonda ndi zinthu zake

CH2OH 2, yomwe ndi diol yosavuta kwambiri. Ethylene glycol ndi madzi opanda mtundu, opanda fungo, otsekemera komanso oopsa pang'ono kwa nyama. Ethylene glycol imatha kusungunuka pamodzi ndi madzi ndi acetone, koma kusungunuka kwake mu ethers ndi kochepa. Amagwiritsidwa ntchito ngati zosungunulira, zoletsa kuzizira komanso zopangira polyester. Polima ya ethylene glycol, polyethylene glycol (PEG), ndi chothandizira kusamutsa gawo ndipo imagwiritsidwanso ntchito pophatikiza maselo.

gwiritsani ntchito

Amagwiritsidwa ntchito makamaka popanga polyester, polyester, polyester resin, yonyowetsa chinyezi, pulasitiki, chogwirira ntchito pamwamba, ulusi wopangidwa, zodzoladzola ndi zophulika, ndipo amagwiritsidwa ntchito ngati chosungunulira utoto, inki, ndi zina zotero, kukonza chothandizira kuzizira kwa injini, chothandizira kuyeretsa mpweya, kupanga utomoni, chingagwiritsidwenso ntchito pa cellophane, ulusi, chikopa, chothandizira kunyowetsa. Chikhoza kupanga utomoni wopangidwa wa PET, ulusi wa PET womwe ndi ulusi wa polyester, botolo la PET lopangira mabotolo amadzi amchere ndi zina zotero. Chingathenso kupanga alkyd resin, glyoxal, ndi zina zotero, zomwe zimagwiritsidwanso ntchito ngati choletsa kuzizira. Kuwonjezera pa kugwiritsidwa ntchito ngati choletsa kuzizira pamagalimoto, chimagwiritsidwanso ntchito poyendetsa mphamvu yozizira m'mafakitale, yomwe nthawi zambiri imatchedwa chonyamulira firiji, ndipo chingagwiritsidwenso ntchito ngati chothandizira kuziziritsa monga madzi.
Zogulitsa za Ethylene glycol methyl ether ndi zosungunulira zachilengedwe zapamwamba kwambiri, monga inki yosindikizira, chotsukira mafakitale, chophimba (utoto wa nitro fiber, varnish, enamel), mbale yokutidwa ndi mkuwa, zosungunulira zosindikizira ndi utoto ndi zosungunulira; Zingagwiritsidwe ntchito ngati zopangira zopangira mankhwala monga zosakaniza za mankhwala ophera tizilombo, zosakaniza za mankhwala ndi madzi opangidwa ndi mabuleki. Monga ma electrolyte a ma capacitor a electrolytic, chosakaniza cha utoto wa ulusi wa mankhwala chopangira khungu, ndi zina zotero. Zimagwiritsidwa ntchito ngati zothandizira nsalu, utoto wamadzimadzi wopangidwa, komanso feteleza ndi kuyeretsa mafuta popanga zinthu zopangira desulfurizer.
Ethylene glycol iyenera kukumbukiridwa ikagwiritsidwa ntchito ngati chosungira chonyamulira:
1. Malo oundana amasintha ndi kuchuluka kwa ethylene glycol mu yankho lamadzi. Pamene kuchuluka kuli pansi pa 60%, malo oundana amachepa ndi kuchuluka kwa ethylene glycol mu yankho lamadzi, koma pamene kuchulukako kupitirira 60%, malo oundana amawonjezeka ndi kuchuluka kwa ethylene glycol, ndipo kukhuthala kumawonjezeka ndi kuchuluka kwa kuchulukako. Pamene kuchulukako kufika pa 99.9%, malo ake oundana amakwera kufika pa -13.2℃, chomwe ndi chifukwa chofunikira chomwe antifreeze yokhazikika (antifreeze mother liquid) singagwiritsidwe ntchito mwachindunji, ndipo iyenera kukopa chidwi cha wogwiritsa ntchito.
2. Ethylene glycol ili ndi gulu la hydroxyl, lomwe lidzasinthidwa kukhala glycolic acid kenako kukhala oxalic acid, kutanthauza glycolic acid (oxalic acid), yokhala ndi magulu awiri a carboxyl, ikagwira ntchito pa 80-90 ℃ kwa nthawi yayitali. Oxalic acid ndi zinthu zake zimakhudza choyamba dongosolo la mitsempha, kenako mtima, kenako impso. Ethylene glycol glycolic acid, zomwe zimayambitsa dzimbiri ndi kutuluka kwa zida. Chifukwa chake, pokonzekera antifreeze, payenera kukhala chosungira kuti chitsulo, aluminiyamu, ndi kupanga sikelo zisamawonongeke.

phukusi ndi mayendedwe

B. Chogulitsachi chingagwiritsidwe ntchito,,25KG，200KG,1000KGBAERRLS。
C. Sungani yotsekedwa m'nyumba pamalo ozizira, ouma komanso opumira mpweya. Zidebe ziyenera kutsekedwa bwino mukatha kugwiritsa ntchito nthawi iliyonse musanagwiritse ntchito.
D. Chogulitsachi chiyenera kutsekedwa bwino panthawi yonyamula kuti chisasakanikirane ndi chinyezi, alkali ndi asidi wamphamvu, mvula ndi zinyalala zina.
