Dipropylene Glycol Dimethyl Ether ine CAS 111109-77-4
Dipropylene Glycol Dimethyl Ether yakapfupikiswa as DPGDME, ine nhamba nhamba 111109-77-4, imhando inoshandiswa zvakanyanya mu polar aprotic solvent. Dpdme solvent ine polarity iri pakati nepakati, inonyungudika nyore nyore mumvura, uye inogona kusanganiswa nezvimwe zvakawanda zvinonyungudika. Dipropylene glycol dimethyl ether imhando yakanaka kwazvo inoenderana ne "water-organic phase". Dpdme solvent imhando inofashaira pakati nepakati, isingabati asi inofanira kuchengetedzwa kure nemoto unodziya zvakanyanya.
Dipropylene glycol dimethyl ether chinhu chinonyungudutsa chinoshanda munzvimbo dzakasiyana-siyana chine hwema hushoma, kumhanya kwakakodzera kwekuputika, kugadzikana kwakanaka kwemakemikari, kunyunguduka kwakanaka uye kuchengetedzeka kwakanyanya kuhutano hwevanhu. United States neEuropean Union dzakanyorwa sezvinhu zvinonyungudutsa zvakasvibira zvisiri zveHAP/NAP (zvisina njodzi pane runyorwa rwekusvibiswa kwemhepo). Dipropylene glycol dimethyl ether 99.0 inogona kushandiswa muzvipfeko zvemvura uye zvakagadziriswa.

Dipropylene glycol dimethyl ether inoshandiswa zvakanyanya muzvikamu zvakasiyana-siyana zvekutsvagisa kwemaindasitiri nesainzi nekuda kwehunhu hwayo hwe "chepfu shoma, kunyunguduka kwakanyanya uye kusagadzikana kwakaderera":
Mapendekete neingi indasitiri:Dipropylene glycol dimethyl ether, semusanganiswa kana kuti co-solvent, inoshandiswa muzviputiro zvemvura, zviputiro zve solvent uye inki. Inogona kuvandudza kunyungudika kwemaresini (akadai se acrylic resins nema polyurethane resins), kuwedzera kuenzana uye kunamira kwemachira, uye panguva imwe chete kuderedza kubuda kwemakemikari anoputika (VOCs).
Mishonga yekuchenesa uye mishonga yekubvisa mafuta:Nekuda kwehunhu hwadzo hwemvura inoyerera uye inopfachukira, dzinogona kushandiswa mu "water-based cleansing agent" yezvigadzirwa zvemagetsi nemidziyo chaiyo. Dzinogona kubvisa mavanga emafuta nemarara emvura (flux residues), uye hadziparadzi zvinhu zvepasi (zvakaita sesimbi nemapurasitiki).
Mumunda wemishonga nemishonga yezvipembenene:Dpdme solvent, se "solvent/co-solvent" yemishonga inoshanda kana mishonga yezvipembenene, inoshandiswa mukugadzira zvinwiwa zvinonwiwa uye mishonga yezvipembenene inosanganiswa. Dipropylene glycol dimethyl ether inogona kuwedzera kunyungudika uye kugadzikana kwemishonga inoshanda uku ichideredza kutsamwa kumuviri wemunhu kana zvirimwa.
Kugadzirwa kwemakemikari uye nzira yekuita nayo:Dipropylene glycol dimethyl ether, semusanganiswa wepolar aprotic, inogona kutsiva zvinonyungudutsa zvine chepfu zvakanyanya uye inoshandiswa mukuita organic synthesis reactions (senge nucleophilic substitution uye catalytic reactions), izvo zvinogona kuwedzera reaction rate uye goho rezvigadzirwa.
Kuzvichengeta wega uye zvigadzirwa zvemakemikari zvezuva nezuva:Dipropylene glycol dimethyl ether inoshandiswa zvishoma muzvigadzirwa zvekuchengetedza ganda uye zvekuzora (zvakaita semafuta ekumeso nezvinonhuwira) sechinhu chinonyungudutsa kana chinonyorovesa, zvichibatsira kunyungudutsa zvinhu zvinoshanda zvinonyungudika mumafuta (zvakaita sevhitamini E), ukuwo zvichiwedzera kunzwa kweganda uye kugadzikana kwezvigadzirwa.
✅China dipropylene glycol dimethyl ether ine mhando yakanaka, yakafanana neDow brand yeUnited States.
✅Kubuda kwepamusoro uye kuwanikwa kwakasimba
✅Kurongedza uye mavara zvinogona kugadziriswa sezvinodiwa
