Dipropylene Glycol Dimethyl Ether yokhala ndi CAS 111109-77-4
Dipropylene Glycol Dimethyl Ether mwachidule as DPGDME, yokhala ndi nambala 111109-77-4, ndi chosungunulira cha polar aprotic chomwe chimagwiritsidwa ntchito kwambiri. Chosungunulira cha Dpdme chili ndi polarity yocheperako, chimasungunuka mosavuta m'madzi, ndipo chimatha kusakanikirana ndi zosungunulira zambiri zachilengedwe. Dipropylene glycol dimethyl ether ndi chosungunulira chabwino kwambiri chogwirizana ndi "gawo la madzi-organic". Chosungunulira cha Dpdme ndi chosungunulira chapakati-chowira, chosayaka koma chiyenera kusungidwa kutali ndi malawi otseguka otentha kwambiri.
Dipropylene glycol dimethyl ether ndi chosungunulira chothandiza chilengedwe chogwira ntchito zosiyanasiyana chomwe chili ndi fungo lokoma losasangalatsa, liwiro loyenera la kusinthasintha kwa kutentha, kukhazikika kwa mankhwala abwino kwambiri, kusungunuka bwino komanso chitetezo champhamvu pa thanzi la anthu. United States ndi European Union zalembedwa ngati zosungunulira zobiriwira zomwe sizili HAP/NAP (zopanda ngozi pamndandanda wa kuipitsidwa kwa mpweya). Dipropylene glycol dimethyl ether 99.0 nthawi zambiri ingagwiritsidwe ntchito popanga zokutira zochokera m'madzi ndi zotsukira.

Dipropylene glycol dimethyl ether imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana ofufuza za mafakitale ndi sayansi chifukwa cha "poyizoni wochepa, kusungunuka kwakukulu komanso kusasinthasintha kochepa":
Zophimba ndi inki makampani:Dipropylene glycol dimethyl ether, monga chosungunulira kapena chosungunulira pamodzi, imagwiritsidwa ntchito mu zophimba zochokera m'madzi, zophimba zochokera ku zosungunulira ndi inki. Ikhoza kusintha kusungunuka kwa ma resin (monga ma resin a acrylic ndi ma polyurethane resin), kukulitsa kulinganiza ndi kumatira kwa zophimba, komanso kuchepetsa nthawi yomweyo kutulutsa kwa mankhwala osasunthika achilengedwe (VOCs).
Zotsukira ndi zotsukira mafuta:Chifukwa cha mphamvu zawo zochiritsa madzi komanso zochiritsa mafuta, zingagwiritsidwe ntchito mu njira zotsukira zochokera m'madzi zomwe zimagwiritsidwa ntchito pazinthu zamagetsi komanso zida zolondola. Zingathe kuchotsa bwino madontho a mafuta ndi zotsalira za flux (zotsalira za flux), ndipo siziwononga zinthu zoyambira (monga zitsulo ndi pulasitiki).
Mu gawo la mankhwala ndi mankhwala ophera tizilombo:Dpdme solvent, monga "solvent/co-solvent" ya zosakaniza zogwira ntchito za mankhwala kapena mankhwala ophera tizilombo, imagwiritsidwa ntchito pokonza zakumwa zamkamwa ndi mankhwala ophera tizilombo omwe amasungunuka mosavuta. Dipropylene glycol dimethyl ether imatha kukulitsa kusungunuka ndi kukhazikika kwa zosakaniza zogwira ntchito pamene ikuchepetsa kuyabwa kwa thupi la munthu kapena mbewu.
Kapangidwe ka mankhwala ndi njira yochitira zinthu:Dipropylene glycol dimethyl ether, monga polar aprotic solvent, imatha kulowa m'malo mwa zosungunulira zachikhalidwe zoopsa kwambiri ndikugwiritsidwa ntchito mu organic synthesis reactions (monga nucleophilic substitution ndi catalytic reactions), zomwe zingawonjezere kuchuluka kwa reaction ndi phindu la mankhwala.
Zosamalira zaumwini ndi mankhwala a tsiku ndi tsiku:Dipropylene glycol dimethyl ether imagwiritsidwa ntchito pang'ono mu zinthu zosamalira khungu ndi zodzoladzola (monga mafuta odzola nkhope ndi zonunkhira) ngati chosungunulira kapena chonyowetsa, chomwe chimathandiza kusungunula zosakaniza zogwira ntchito zosungunuka ndi mafuta (monga vitamini E), pomwe chimawonjezera kumveka bwino kwa khungu ndi kukhazikika kwa zinthuzo.
✅China dipropylene glycol dimethyl ether ndi yabwino kwambiri, yofanana ndi mtundu wa Dow wa ku United States.
✅Kutulutsa kwakukulu komanso kupezeka kokhazikika
✅Mapaketi ndi zilembo zitha kusinthidwa malinga ndi momwe mukufunira
