Kua tukatuka REVODE101 e maroke whātioatanga, i muri nei, te pūmautanga wera rawa o te teriuma ko 110 ℃, me te ihirangi makuku he iti iho i te 200 ppm. Ka taea te whakamahi tika i te kāpia i rongoa i roto i te putea Aluminium konumohe, tiakina pouaka ranei putea i waho. Re-whakamaroke o te teriuma taea te hanga i te ihirangi makuku raro atu i te 100 ppm, i te mea pai ki te whakarei ake i te processability o te teriuma me te kounga o te pepa.
A, no te anō-maroke te kāpia, kua araia hoki te hau wera un-dehumidified, hoki kahore whakakore haukū, e kore anake e kore e taea te whiwhi te pānga whakamaroke, engari e taea hoki e te whakatere te tere o te absorbance wai o urutaung teriuma. Ka taea e te rangi dehumidified kī te pānga whakamaroke o urutaung teriuma i desiccator.
E whakaaturia Fokotu◊u ki tikanga whakamaroke urutaung i te tepu e whai ake:
| Tawhā Drying | Tautuhinga angamaheni |
| Residence Time ( haora ) | 2-3 |
| Temperature Air ( ℃) | 90 |
| Air Dew Point ( ℃) | -40 ~ -42 |
| Air Rere Auau ( m3 / kapia hr-kg ) | > 1,85 |
Ka taea te makamaka rauemi whakahou (kia te rauemi whakahou kore roa atu i te 3 marama, a kahore neke atu i te 35% i roto i te matatini). Nā ki te tono kia waiho te ihirangi makuku o whārangi Tangohanga raro atu i te 200 ppm, me mahi i te rauemi whakahou ki te whātioatanga me nui-pāmahana whakamaroke i te pūrere desiccant.
Tikanga whātioatanga 1:
taputapu whātioatanga General mo PET he manakohia. Hei tauira, ka tīpakohia 0.5 m3 whātioatanga autoclave te, kia konatunatua nga rauemi homogeneously, ki te 1: 1 te ōwehenga taimaha o rauemi whakahou ki urutaung parakore. I muri i te tāpiri ki te autoclave whātioatanga, tīmata te whātioatanga warming o matatini i raro i te ranu i te tere o te 3 rpm. Whakaturia te pāmahana te i 60 ℃ mo 20min, 80 ℃ hoki 10 min, 95 ℃ hoki 10men, i muri i 110 ℃ mo 30 min, a ka Petehemehe pāmahana taahiraa i te taahiraa. Pumau te tukanga whātioatanga katoa hoki e pā ana ki 1.5 haora.
Tikanga whātioatanga 2:
Na roto i te te whakamahi i te taputapu whātioatanga pōkākā Kreyenborg, e te tahu nga rauemi i pōkākā, haere tahi i te hurihanga Mixing i muri i te tāpiri ki te whātioatanga pōkākā okeoke oko. Ko te kaiaka o tenei tikanga, ko te e kawea te whātioatanga me tukanga whakamaroke i i te wa ano, a taea te mutu te tukanga i roto i 15 ~ 20 min.
Tikanga whātioatanga 3:
I muri i te mua-maroke i iti-pāmahana, ka kia extruded nga rauemi whakahou, me te palletized, i muri i reira, e taea te mahi i te tukanga whātioatanga i roto i taputapu whātioatanga PET.
Ka taea te makamaka Bits me nga wahi hoki e rave rahi mau taime: Note. I roto i te tukanga anō o ngā rauemi whakahou, he nui iti o te kaihoko kaiāwhina - taea te tāpiri ADR ki te whakaiti i te āhuatanga heke o ngā rauemi whakahou tōtika, me te nui tūtohutia he 0.1 ~ 0.6%.
Kinonga wairākau
te urutaung taea te whakatutuki biodegradation tonu i roto i 180 nga ra i raro i ngā āhuatanga wairākau kinonga, ka ko nga hua whakamutunga hauhā me te wai. Ko te tikanga wairākau e whai ake nei:
○ Temperature ko 58 ± 2 ° C
○ haumākū he 98%
○ He etahi microorganisms
Tanú kinonga
He rerekē i te tikanga wairākau te tikanga tanú. Na reira, ko te auau kinonga o urutaung kinonga puhoi, te tikanga e 2-5 tau, engari e kore e nga hua kinonga whakapokea te manawa whenua i waho whakangaro i te tupu tipu, a kore ururua te whenua ngakia, a te mutunga ko reira tino inā tonu.
Incineration
He iti te uara parariraa o urutaung, a ko nga hua parariraa oti te hauhā me te wai, e kore e nei whakapokea te rangi.
e urutaung tau rauemi whakahou - witi, te cassava me ētahi atu tipu rite rauemi raw. I muri i te FERMENTATION i microorganisms, ka kia tangohia waikawa lactic, na ka kia hua urutaung roto i te tukanga o te para, maroketanga polymerization, pyrolysis pāmahana tiketike, me te polymerization whakamutunga. Urutaung He taonga pōpopo pai. I muri i te hokonga atu, i roto i te tau kotahi, e taea te iti te reira ki te hauhā me te wai waro i microorganisms i te oneone, a ka mahi i tetahi mea kino e ki to tatou taiao. Urutaung Ko te ahua o te pareaku tīmeka ki ngā āhuatanga taketake o ngā rauemi micromolecule whānui. He urutaung āhuatanga machanical pai, te na'ina'iraa iti, a he matatau ki te tono o te nuinga o kirihou waihanga, hoki ngā whakamahia whānuitia te reira i roto i te hanga o ngā rauemi mōkihi, hokona tuku, anga whare pūrere hiko, te muka, kai 3D etc.
No te mea ahu mai urutaung i resoures tipu whakahou, engari e kore e nga kirihou tuku iho e hāngai ana hinu-, kia taea truely ite i te reira pūngao-whakaora me te tiaki enviromental, ka whakaaro urutaung te ki hei te tino whaihua "rauemi kaiao" hou.
