REVODE101 icutshungulwe nge iphele crystallization, ngemva kwalokho, amazinga aphakeme ukushisa ukuzinza resin kuyinto 110 ℃, futhi okuqukethwe umswakama lingaphansi kuka 200 ppm. Resin ukuthi agcinwe esikhwameni Aluminium ucwecwe, ivikelwe ibhokisi noma esikhwameni ngaphandle ingasetshenziswa ngqo. Phinda omiswe resin ungenza okuqukethwe umswakama ngaphansana 100 ppm, okuyinto ezikahle ukuthuthukisa processability we resin kanye nekhwalithi ishidi.
Lapho kabusha iphele resin, emoyeni un-dehumidified ashisayo asivumelekile, ngoba ngaphandle dehumidifier, hhayi kuphela ukusebenza omiswe ngeke kutholakale, kodwa futhi ijubane amanzi absorbance of PLA resin kungenziwa ngesivinini esikhulu. Umoya dehumidified kungaqinisekisa umphumela omiswe PLA resin e desiccator.
PLA izimo omiswe eziphakanyisiwe ziboniswa etafuleni elandelayo:

Izinto Wemvelo lingasetshenziswa kabusha (izinto uvuseleleke kufanele abe made hhayi kuka 3 izinyanga, futhi engekho ngaphezulu kuka-35% ngo-eziyinkimbinkimbi). Ngenxa funa ukuthi okuqukethwe umswakama ishidi extrusion kufanele kube ngaphansana 200 ppm, izinto uvuseleleke kumelwe kubhekanwe nakho crystallization futhi ephezulu lokushisa omiswe yidivayisi desiccant.
Crystallization indlela 1:
Jikelele imishini crystallization ngoba PET kwamukelekile. Ngokwesibonelo, lapho 0.5 m3 crystallization autoclave ekhethiwe, izinto okufanele zixutshwe homogeneously, nge 1: 1 isisindo ratio izinto ivuselelwe PLA okumsulwa. Ngemva kokuba sesingezwa autoclave crystallization, crystallization Ukushisa eziyinkimbinkimbi waqala ngaphansi ukuxuba ngesivinini 3 ngomzuzu. Amazinga isethwe 60 ℃ for 20min, 80 ℃ for 10 min, 95 ℃ for 10min, ekugcineni ngesikhathi 110 ℃ amaminithi angu-30, bese lokubhonsa lokushisa step by step. Lonke crystallization inqubo ithatha cishe 1.5 ihora.
Crystallization indlela 2:
Ngokusebenzisa Kreyenborg infrared imishini crystallization, izinto abathukuthelela ngu-infrared, ephelezelwa Ukujikeleza kuhlangana ngemva kokuba sesingezwa crystallization infrared kweqa emgqonyeni. Inani le ndlela wukuthi crystallization futhi inqubo yokoma kwamanzi abazenzi ngesikhathi esifanayo, futhi inqubo kungenziwa yaphela ngaphakathi 15 ~ 20 imiz.
Crystallization indlela 3:
Ngemva kokuba pre-omisiwe at aphansi-lokushisa, izinto uvuseleleke uzobe extruded futhi palletized, ngemva ke, inqubo crystallization kungenziwa PET imishini crystallization.

Qaphela: Amabhithi futhi izingcezu lingasetshenziswa kabusha izikhathi eziningana. Phakathi nenqubo kabusha izinto evuselelekayo, inani elincane ejenti umsizi - ADR kungenziwa wanezela ukunciphisa izakhiwo nokwehla izinto evuselelekayo ngempumelelo, kanye nenani Isincomo 0.1 ~ 0.6%.

Nokucekelwa Umquba
I PLA ingafinyelela biodegradation umnyuziki ezinsukwini ezingu-180 ngaphansi kwezimo umquba ihlazo, futhi imikhiqizo yokugcina kukhona i-carbon dioxide futhi amanzi. Imibandela Composting zimi kanje:
○ Izinga lokushisa kuyinto 58 ± 2 ° C
○ Ukuswakama 98%
○ Kukhona nezilwanyana ezincane ezithile

Landfill nokucekelwa
Imibandela landfill bengafani izimo Composting. Ngakho-ke, izinga nokwehliswa kwesithunzi PLA nokucekelwa uyephuza, ngokuvamile kuthatha iminyaka 2-5, kodwa imikhiqizo nokucekelwa Aziyingcolisi komhlaba ngaphandle kokubhubhisa ekukhuleni kwesihlahla nasekuvezeni izithombo, hhayi izwe otshaliwe, futhi ekugcineni kusenzima okonakele ngokugcwele.

Nokushiswa
Inani omlilo of PLA incane, futhi imikhiqizo amandla omlilo ngokuphelele kukhona i-carbon dioxide bese amanzi, okuyinto Aziyingcolisi emoyeni.

PLA uthatha minyaka yonke imithombo evuselelekayo - corn, umdumbula nezinye izitshalo njengoba impahla eluhlaza. Ngemva ukuvutshelwa by nezilwanyana ezincane, acidosis acid uzobe ekhishwe ke PLA uzobe kukhiqizwa ngokusebenzisa inqubo yokucwenga, amanzi emzimbeni polymerization, lokushisa high pyrolysis futhi polymerization sokugcina. PLA ine omuhle kakhulu impahla okubolayo. Ngemva kulahlwa, kungakapheli unyaka owodwa, kungashiwo phansi ku-carbon dioxide futhi amanzi by nezilwanyana ezincane emhlabathini, futhi singazilimazi imvelo yethu. PLA uhlobo polyester aliphatic ezinezici eziyisisekelo jikelele micromolecule izinto. PLA anezakhi ezinhle machanical, ukuncipha ongaphakeme, futhi abanekhono isicelo amapulasitiki kakhulu zokwenziwa, futhi ukuthi kabanzi ukukhiqizwa iphakethe izinto, tableware alahlwayo, yasendlini izinto zikagesi igobolondo, fibre, Izimpahla 3D njll

Ngenxa PLA sivela uvuseleleke isitshalo resoures kodwa hhayi amapulasitiki bendabuko petroleum-based, ngakho-ke ungakwazi truely bona energy osindisa futhi nokuvikelwa enviromental, futhi PLA ubhekwa le ethembisayo "impahla imvelo" entsha.
