I. Whakataki Poto mō te Hua: He Whakarewa Kohua-Nui, Mahi-Teitei
Ko te Diethylene Glycol Monobutyl Ether, e whakarapopototia ana ko DEGMBE, ko BDG rānei, he whakarewa waro mārama, kore tae, he kakara ngoikore rite ki te butanol. Hei mema matua o te whānau glycol ether, kei roto i tōna hanganga ngota ngā here ether me ngā rōpū hydroxyl, e whakawhiwhi ana ki ngā āhuatanga ā-tinana me te matū ahurei e hanga ana hei "whakarewa maha-whakamahinga" pai rawa atu, e koropupū ana, e iti ana te ngaohiko.
Ko ngā kaha matua o DEGMBE kei roto i tōna wairewatanga me tōna kaha honohono. He kaha tōna wairewatanga mō ngā momo matū polar me ngā matū kore-polar, pērā i ngā kapia, ngā hinu, ngā tae, me te cellulose. He mea nui ake, he mahi honohono a DEGMBE, e āhei ai ngā pūnaha kāore i te hototahi i te tīmatanga (hei tauira, te wai me te hinu, ngā kapia waro me te wai) ki te hanga i ngā otinga, i ngā emulsions rānei, he pumau, he ōrite. Ko tēnei āhuatanga nui, me tōna tere mimiti ngawari me te āhuatanga whakataurite pai, ka whakatakoto i te turanga mō ngā tono whānui a DEGMBE i roto i ngā mara e whai ake nei:
●Ahumahi Paninga me te Waituhi: Whakamahia hei whakarewa me te kaihopu i roto i ngā peita wai, ngā peita rapa, ngā peita tunu kai ahumahi, me ngā waituhi tā, ka whakapai ake i te taumata me te kanapa o te kiriata, me te ārai i te pakaru o te kiriata i ngā pāmahana iti.
●Ngā Kaihoroi me ngā Kaiwhakatāra Peita: He wāhanga matua o te maha o ngā kaihoroi ahumahi mahi-teitei, ngā kaiwhakawātea hinu, me ngā kaiwhakatāra peita, ka whakarewa pai a DEGMBE i ngā hinu me ngā kiriata peita tawhito.
●Te Tukatuka Kakahu me te Hiako: Hei whakarewa mō ngā tae me ngā tāpiringa, hei āwhina i te urunga ōrite.
●Ngā Matū Hiko: Ngā mahi i roto i ngā mīhini tango whakaahua-ātete me ētahi otinga horoi hiko.
●Ētahi atu Marae: Whakamahia ki ngā patu pepeke, ngā wai mahi whakarewa, ngā piripiri polyurethane, me ētahi atu.
Nō reira, ahakoa kāore a DEGMBE e hanga tika i te tinana matua o ngā rauemi pēnei i ngā monomer papatipu, he "MSG ahumahi" nui tonu tana mahi - he tūranga nui ki te whakarei ake i te mahi hua me te pumau o ngā tukanga puta noa i ngā ahumahi maha o muri mai.
II. Ngā Pūrongo Hou: He Mākete i raro i te iti o te tuku me te tono me ngā utu nui
Nō nā tata nei, i runga i te āhua o ngā whakarerekētanga mekameka ahumahi o te ao me te pōturi o ngā rauemi mata, kua kitea te mākete DEGMBE e te iti o te tuku me ngā taumata utu nui.
Ka tautokona te kaha e te ngoikore o te ethylene oxide rauemi mata
Ko ngā rauemi matua mō te hanga DEGMBE ko te ethylene oxide (EO) me te n-butanol. Nā te āhua mura me te pahū o te EO, he iti noa te rahinga o tōna tohatoha arumoni, me ngā rerekētanga utu ā-rohe me ngā piki me ngā heke. Nō nā tata nei, kua noho tonu te mākete EO ā-rohe ki te taumata utu teitei, nā ngā ia o te ethylene me ōna ake āhuatanga tuku-tono, e tautoko ana i te utu mō DEGMBE. Ko ngā piki me ngā heke o te mākete n-butanol ka pā tika ki ngā utu o DEGMBE.
Te Putea Tūmau
I tētahi taha, kua kati ētahi o ngā whare hanga nui mō te tiaki i ngā wā kua taha ake nei, ā, kua pāngia te tuku i ngā taonga i te wā kotahi. I tētahi atu taha, kei te iti tonu te rahi o ngā taonga o te umanga katoa. Nā tēnei kua kore e nui te DEGMBE i te mākete, ā, kei te mau tonu ngā kaipupuri i ngā whakaaro mō te utu tika.
Te Hiahia Rerekē o te Rerenga
Hei te rāngai hoko nui rawa atu a DEGMBE, he hononga tata te hiahia o te umanga paninga ki te angitu o te hoko whenua me te hanganga hanganga. I tēnei wā, kei te pumau tonu te hiahia mō ngā paninga hoahoanga, engari ko te hiahia mō ngā paninga ahumahi (hei tauira, ngā paninga motuka, moana, me ngā paninga ipu) e whakarato ana i te hihiri mō te mākete DEGMBE. Kei te pumau tonu te hiahia i roto i ngā mara tuku iho pērā i ngā kaihoroi. Ko te whakaae a ngā kiritaki o raro ki te DEGMBE utu nui kua waiho hei arotahi o ngā kēmu mākete.
III. Ngā Auahatanga Ahumahi: Te Whakapai Ake i te Taiao me te Whakawhanaketanga Whakapai Ake
I te tirohanga whakamua, ka hono tata te whanaketanga o te umanga DEGMBE ki ngā ture taiao, te ahunga whakamua hangarau, me ngā huringa o te hiahia o te mākete.
Ngā Kōrero mō te Whakapai Ake me te Whakakapinga Hua i Ārahihia e ngā Ture Taiao
Ko ētahi whakarewa glycol ether (ina koa ko te raupapa-E, pērā i te ethylene glycol methyl ether me te ethylene glycol ethyl ether) he mea tino herea nā te mea he āwangawanga mō te paitini. Ahakoa he iti te paitini o te DEGMBE (kua whakarōpūtia i raro i te raupapa-P, arā, ngā propylene glycol ether, engari i ētahi wā ka kōrerohia i roto i ngā whakarōpūtanga tuku iho) ā, he whānui ngā whakamahinga, ko te ia o te ao o te "matū matomato" me te whakaiti i ngā tukunga VOC (Volatile Organic Compounds) kua pēhi i te umanga whakarewa katoa. Nā tēnei i akiaki te R&D o ngā momo rerekē e pai ake ana ki te taiao (hei tauira, ētahi propylene glycol ethers) ā, i akiaki i a DEGMBE kia whanake ki te parakore teitei ake me ngā taumata poke iti iho.
Ka Whakatairangahia te Whakahoutanga Ahumahi o te Awaawa e te Whakapai Ake i te Tono
Nā te tere o te whanaketanga o ngā paninga ahumahi kounga teitei (hei tauira, ngā peita ahumahi wai-pūtake, ngā paninga totoka-teitei), ngā waituhi mahi-teitei, me ngā matū hiko, kua nui ake ngā whakaritenga mō te parakore o te whakarewa, te pumau, me ngā matū toenga. Nā tēnei, me whakapakari ake ngā kaihanga DEGMBE i te mana whakahaere kounga me te whakarato i ngā hua DEGMBE kua whakaritea, kua teitei ake rānei ngā whakaritenga e tutuki ai ngā hiahia tono kounga-teitei.
Ngā Huringa o te Tauira Pūmanawa Whakaputa Rohe
Ko te kaha whakaputa DEGMBE o te ao e aro nui ana ki Haina, Amerika Te Raki, Ūropi ki te Hauāuru, me ētahi atu wāhanga o Āhia. I ngā tau tata nei, kua piki haere tonu te kaha whakaputa me te awe o Haina, e tautokona ana e te mekameka ahumahi katoa me te mākete nui o raro. I te heke mai, ka haere tonu te whakatakotoranga kaha whakaputa ki te tata atu ki ngā mākete kaihoko nui, ā, ko ngā utu taiao me te haumaru ka noho hei mea matua e pā ana ki te whakataetae ā-rohe.
Arotau Tukanga me te Whakaurunga Mekameka Ahumahi
Hei whakarei ake i te whakataetae utu me te pumau o te tuku, ka arotauhia e ngā kaihanga matua ngā tukanga whakaputa DEGMBE mā te whakapai ake i te hangarau, te whakanui ake i te whakamahinga o ngā rauemi mata me te hua o te hua. I taua wā, ko ngā umanga he kaha ake te ātete ki ngā mōrearea i roto i te whakataetae mākete, ā, he kaha ake te ātete ki ngā mōrearea i roto i te whakataetae mākete.
Hei whakarāpopototanga, hei whakarewa mahi matua, he hononga tata te mākete o DEGMBE ki ngā rāngai hangahanga o raro pērā i ngā paninga me te horoi—he "paerewa" tēnei mō ō rātou hua. I te aroaro o ngā wero rua o te pēhanga utu rauemi mata me ngā ture taiao, kei te rapu te umanga DEGMBE i te taurite hou me ngā whai wāhitanga whanaketanga mā te whakapai ake i te kounga hua, te arotau i ngā mekameka tuku, me te urutau ki te tono nui o raro, me te whakarite kia mau tonu te tūranga nui o tēnei "whakarewa maha-whakamahinga" i roto i te pūnaha ahumahi hou.
