Chii chinonzi Methoxypolyethylene Glycols CAS 9004-74-4?

Polyethylene glycol monomethyl ether inobva mu polyethylene glycol. Inonyungudika mumvura, ethanol uye mune zvinonyungudutsa zvakanyanya zve polar organic. Haichinjiki zvakanyanya pane glycerol, ine makemikari akasimba, hainyungudike nyore uye haiparadzwe, uye ine hydrophilicity yakasimba. Ine vapor pressure yakaderera uye inogara yakagadzikana pakupisa. Inoshandiswa sechinokora uye mafuta muindasitiri yekudhinda nekudhaya machira uye indasitiri yemakemikari yezuva nezuva. Muindasitiri yezvinhu zvekuvaka, inoshandiswa sezvinhu zvekugadzirisa mvura nesimende uye zvinosimbisa. Polycarboxylic acid inoderedza mvura inoshanda zvakanyanya yakagadzirwa uchishandisa zvinhu izvi zvine simba rakasimba rekuchengetedza kupararira kwezvidimbu zvesimende, zvichiita kuti chigadzirwa chive nemabhenefiti emuyero mudiki, mwero wekuderedza mvura yakawanda, simba rakanaka rekusimbisa, kugara kwenguva refu, kusaora kwesimbi uye hushamwari hwezvakatipoteredza. Inogona kushandiswa mukongiri yekutengeserana inoshanda zvakanyanya, yakasimba (C60 kana kupfuura) yekusanganisa panzvimbo uye kutakurwa kure.
