Dipropylene Glycol Dimethyl Ether me te CAS 111109-77-4
Dipropylene Glycol Dimethyl Ether whakarāpopototanga as DPGDME, me te nama cas 111109-77-4, he whakarewa aprotic porowhita e whakamahia whānuitia ana. He porowhita ngawari te whakarewa Dpdme, he ngāwari te wairewa ki te wai, ā, ka taea te whakaranu ki te nuinga o ngā whakarewa waro. He whakarewa pai rawa atu te Dipropylene glycol dimethyl ether hei hototahi ki te "wāhanga wai-waro". He whakarewa ira-waenga te whakarewa Dpdme, kāore e mura engari me waiho kia matara atu i ngā mura tuwhera pāmahana teitei.
He whakarewa taiao maha-kaupapa te Dipropylene glycol dimethyl ether, he kakara reka, he tere whakapūmau, he pumau matū pai, he wairewa pai, ā, he haumaru hoki mō te hauora tangata. Kua whakarārangihia te Hononga o Amerika me te Kotahitanga o Ūropi hei whakarewa matomato mō te kore HAP/NAP (kore morearea i roto i te rārangi parahanga hau). Ka taea te whakamahi i te Dipropylene glycol dimethyl ether 99.0 i roto i ngā paninga wai me ngā paninga kua whakamaroketia.

E whakamahia whānuitia ana te dipropylene glycol dimethyl ether i roto i ngā mara rangahau ahumahi me te pūtaiao nā te mea he "iti te paitini, he nui te wairewatanga, he iti hoki te piki me te heke":
Te umanga paninga me te waituhi:Ko te dipropylene glycol dimethyl ether, hei whakarewa, hei whakarewa tahi rānei, e whakamahia ana i roto i ngā paninga wai, i ngā paninga whakarewa me ngā waituhi. Ka taea e ia te whakapai ake i te wairewatanga o ngā kapia (pēnei i ngā kapia kiriaku me ngā kapia polyurethane), te whakarei ake i te whakataurite me te piri o ngā paninga, me te whakaiti i te tukunga o ngā matū waro mimiti (VOC).
Ngā kaihoroi me ngā kai tango hinu:Nā te mea he āhuatanga wai-aroha me te lipo-aroha, ka taea te whakamahi i roto i ngā whakatakotoranga "kaihoko horoi wai-hangai" mō ngā wāhanga hiko me ngā taputapu tino tika. Ka taea e rātou te tango pai i ngā paru hinu me ngā toenga rere (ngā toenga rere), ā, kāore e waikura i ngā rauemi turanga (pērā i ngā konganuku me ngā kirihou).
I roto i te mara o te rongoā me ngā patu pepeke:Ko te whakarewa Dpdme, hei "whakarewa/whakarewa-tahi" mō ngā matū hohe o ngā rongoā, ngā patupatu rānei, e whakamahia ana i roto i te whakarite wai ā-waha me ngā patupatu kukū emulsable. Ka taea e te dipropylene glycol dimethyl ether te whakarei ake i te wairewatanga me te pumau o ngā matū hohe, me te whakaiti i te riri ki te tinana tangata, ki ngā hua rānei.
Te hanganga matū me te reo tauhohenga:Hei whakarewa aprotic pōro, ka taea e te dipropylene glycol dimethyl ether te whakakapi i ngā whakarewa tino paitini tuku iho, ā, ka whakamahia hoki i roto i ngā tauhohenga hanga rauropi (pēnei i te whakakapinga nucleophilic me ngā tauhohenga catalytic), ka taea te whakanui ake i te tere tauhohenga me te hua hua.
Ngā hua tiaki whaiaro me ngā hua matū o ia rā:Ka whakamahia te dipropylene glycol dimethyl ether i roto i ngā rahinga iti i roto i ngā hua tiaki kiri me ngā mea whakapaipai (pēnei i ngā kirīmi kanohi me ngā hinu kakara) hei whakarewa, hei whakamakuku rānei, hei āwhina i te whakarewa i ngā matū hohe wairewa-hinu (pēnei i te huaora E), me te whakarei ake i te ahua o te kiri me te pumau o ngā hua.
✅He pai te kounga o te dipropylene glycol dimethyl ether o Haina, he rite ki te waitohu Dow o te Hononga o Amerika
✅ He nui te putanga me te pumau o te tuku
