Triethylene Glycol

Ko te Triethylene glycol (TEG), me te tātai matū C₆H₁₄O₄ me te nama CAS 112-27-6, he matū polyether mahi-teitei e mōhiotia ana mō tōna āhua hygroscopicity tino pai, te pumau matū, me te wairewa maha-whakamahinga. Hei wai kore tae, kore kakara, me te matotoru, ka tū te TEG hei rauemi mata pono me te āwhina tukatuka puta noa i ngā rāngai ahumahi maha, e tuku ana i te mahi pumau i roto i ngā tono nui.

Ngā Taupānga Matua o te Triethylene Glycol

Ahumahi Hau me te Hinu Taiao
E whakamahia whānuitia ana te TEG hei matū whakamaroke mō te hau māori, te hau hinu wai (LPG), me ngā awa warowaihā. Nā tōna kaha ki te waikura ka taea te tango pai i te makuku kia tutuki ai ngā paerewa kawe paipa, ā, ka ārai i te hanganga waikura me te waikura o ngā taputapu. Ka whakamahia hoki te Triethylene Glycol i roto i ngā tukanga whakareka hau hei whakarei ake i te pai o te purenga.
Te Hanganga Matū
Hei takawaenga matua, ka whakamahia te Triglycol hei rauemi mata mō te hanga o:
Ngā kapia polyester, ngā polyurethane, me ngā mea hanga kirihou
Ngā etera glycol (hei tauira, te triethylene glycol monomethyl ether)
Ngā ester mō ngā hinu whakahinuhinu me ngā paninga motuhake
Ngā whakatakotoranga surfactants me te hopi horoi
Ngā Ahumahi Rongoā me te Whakapaipai
Hei whakawaiwai i roto i ngā mea whakapaipai, ngā hua tiaki kiri, me ngā taonga tiaki whaiaro (hei tauira, ngā hinu kiri, ngā kirimi, ngā hopi horoi makawe) hei pupuri i te makuku me te whakapai ake i te āhua o te kiri.
Hei whakarewa me hei whakau i roto i ngā whakatakotoranga rongoā, tae atu ki ngā rongoā ā-waha, ngā kirīmi pani, me ngā pūnaha tuku rongoā.
Whakamahia ana i roto i ngā tāpiringa kai (ngā tohu e tutuki ana i ngā whakaritenga a te FDA) hei pupuri makuku mō ngā kai tunua me ngā mea reka.
Ngā Whakamahinga Ahumahi kē atu o te Triethylenglycol
Wai whakawhiti wera: E whakamahia ana i roto i ngā pūnaha whakamahana/whakamatao porowhita-katia nā te mea he teitei te kohua me te pumau o te pāmahana.
Ahumahi kakahu: He mahi whakangawari, he mahi ārai-patū, he mahi tāpiri tae hei whakapai ake i te kounga o te kakahu.
Waituhi tā: Ka whakarei ake i te rere o te waituhi, te piri, me te ātete ki te makuku i roto i ngā mahi tā arumoni.

Ngā Painga o te Triethylenglycol

Teitei o te Parakore: Kei te wātea ngā kōwhiringa mō te taumata ahumahi (≥99.5% te parakore) me te taumata rongoā (≥99.9% te parakore), e tutuki ana i ngā paerewa ahumahi tino pakari (e tutuki ana i te ISO, FDA, REACH).
Pūmautanga Tino Pai: Ka ātete ki te waikura me te waikura i raro i ngā āhuatanga mahi noa, kia roa ai te ora.
He iti te paitini: Kāore e whakapataritari i te kiri (ina tika te whakahaere) ā, he pai mō te taiao, he pirau hoki.
Hototahi Whānui: Hototahi ki te nuinga o ngā rauemi rauropi me ngā rauemi kore-rauropi, e āhei ai te whakaurunga maeneene ki ngā tukanga whakaputa o nāianei.
Kounga Pūmau: I hangaia mā roto i ngā hangarau whakahoro me te purenga matatau, kia rite ai te ōritetanga o ia puranga.

Ngā Aratohu Whakahaere me te Rokiroki mō te Triethylene Glycol

Rokiroki: Puritia ki roto i ngā ipu hiri, ātete-waikura (HDPE, maitai kore waikura) ki te wāhi hauhautanga, maroke, me te hauhautanga pai. Āraia te rā tika me te pānga ki ngā pāmahana tiketike (penapenahia ki raro i te 30°C).
Te Whakahaere: Whakamahia ngā taputapu tiaki whaiaro e tika ana (ngā karapu, ngā mōhiti kanohi, ngā kākahu tiaki) hei ārai i te pa ki te kiri me ngā kanohi. Mēnā ka maringi, mimitia ki ngā rauemi kore e pakaru (hei tauira, te onepu, te vermiculite) ka maka atu i runga anō i ngā ture taiao ā-rohe.
Te roanga o te oranga mō te Triethylene Glycol: 24 marama mai i te rā i hangaia ai mēnā ka rongoatia i raro i ngā tikanga kua tūtohutia.
