Yuav ua li cas zaub mov - Txoj Haujlwm Ntim Hluav Taws Xob

Ib puag ncig qhov tseem ceeb

Xav txog 67,000 lub hwj yas hloov mus rau hauv ib tons ntawm ib qho khoom siv ntawm cov roj, txuag 0.0364 tons roj, thiab conserving 6.2 tons dej. Qhov no tsis muaj hnub nyoog futuristic; Nws yog qhov tseeb ntawmRov ua dua cov polyethylene terephthalate (rpet)Cov zaub mov ntim khoom noj. Raws li cov cai thoob ntiaj teb zoo li European plastics pact compate 30% siv cov ntsiab lus hauv 2025, cov tuam ntxhab tau sib tw mus rau cov zaub mov zoo nkauj- rpet rpet kev tsim khoom. Tab sis zoo li cas raws nraim li cas discarded fwj ua lub ntsej muag -} npaj ntim?

 

Kauj ruam 1: Txheeb thiab ua ntej {- ua - lub hauv paus ntawm kev coj dawb huv

Cov lus pib pib nrog kev xaiv nruj. Sau tus tsiaj lub hwj yog muab cov xim (pob tshab, ntsuab, xiav) thiab cov hom kom zam kom tsis txhob muaj paug. Pob tshab flakes ua tus nqi hwm, thaum xim ntws - Tus nqi siv zoo li cov ntaub pua plag fibers {}} Tam sim no roj rpet kiv puag ncig.

 

Tom qab txheeb, fwj yog:

 

Crushed rau hauv flakes(0.15-0.4 hli tuab)

 

NtxuavHauv Alkaline Solutions (80-85 degree) kom tshem cov ntawv cim, cov nplaum, thiab cov seem

 

Qhuav thiab limsiv electrostatic sepranators lossis cov tshuab roj hmab kom tshem tawm cov lw hlau lossis PVC

 

Why it matters: Food-grade RPET requires >99.9% Purity. Ib qho ib tug PVC cov khib tuaj yeem ua rau tag nrho cov pob.

 

 

Kauj ruam 2: Kev Ua Si Sib Tsoo - Lub tsev cov zaub mov -}} kev nyab xeeb

Extrusion & Decontamination

Flakes yog yaj thiab extruded nyob rau hauv nqus tsev kom tshem tawm cov tsis huv volatile tsis muaj kuab paug {}} roj, noo noo, lossis residual dej. Cov khoom tseem ceeb ntxiv zoo likhaib nyeem ntsevtej zaum yuav tau qhia ntawm no kom neutralize daj hauv cov xim flakes.

 

Cov khoom - Xeev Polycondensation (SSP): Qhov kev ua si- changer

Nov yog qhov engineering ua tau raws li Chemistry. Flakes lossis pellets yog crystallized thiab rhuab mus rau 200-230℃hauv inert {}} roj reactors rau 8-24 teev. SSP ua tiav peb lub hom phiaj tseem ceeb:

 

Boosts intrinsic viscosity (iv)los ntawm ~ 0.65 dl / g rau 0.82+ dl / g -} tseem ceeb rau lub raj mis muaj zog

 

Txo cov acetaldehyde(ib qho kev cuam tshuam los ntawm kev ua haujlwm) kom tsawg dua lossis sib npaug rau 1.5 ppm (FDA txwv)

 

Dilontaminates microbiologically, ntsib EFSA / FDA cov qauv

 

Cov kev tsom iav tech: cov tuam txhab zoo li EREMA (Austria) thiab Buhler (Switzerland)

 

Kauj ruam 3: Kev tsim khoom siab heev - Kev nrawm ntsib tau pom kev ruaj khov

rpet ntawv ntau lawm

Rau cov tais thermoformed lossis khob, rpet pellets yauv musAba co -} Extrusion:

 

{- txheej:Nkauj xwb tus tsiaj (sab nraud)

 

B - txheej:100% rpet (tub ntxhais)

 

{- txheej:Nkauj xwb tus tsiaj (khoom noj {{{}}}} sib tiv tauj nto)

 

Cov neeg siv cov ntaub thaiv ntawm cov neeg muaj peev xwm kis tau zoo thaum ua cov ntsiab lus siab tshaj plaws (txog li 95%).

 

Txhaj tshuaj molding tawm tsam

Engel's E - Ceev hybrid tshuab tam sim no pwm 0.2}} backphasing tshuab {}}}} moulding. TSEEM CEEB LOJ Muaj xws li:

 

1400 hli / Sec Txhaj Tshuaj CeevThaum 2,600 bar siab

 

Tshwj xeeb screwsTuav 100% rpet tsis muaj viscosity poob

 

Hauv - moulding LabellingNrog rov ua dua tshiab - share cov nplaum

 

Kev lees paub zoo: cov ntaub thaiv npog

Khoom noj khoom haus - qib rpet tsis yog kwv yees. Ua raws li:

 

EFSA / FDA Txheej Txheem Pov ThawjKev Txiav Txim Siab

 

Nruj ntsuasRau cov hlau hnyav, phthalates, thiab ethylene glycol

 

Traceausility Raws CaiZoo li GRs lossis ISCUS ntxiv

 

Sidel's Refetable ™ platform ua yeeb yam no Rigor, simulating rov ua dua chains kom cov khoom tsis huv ntawm cov kaus mom, cov ntawv cim, lossis cov nyom.

 

Ib puag ncig Roi: Tshaj kev kuaj cov roj teeb

Thaum RPET Slashes CO2 los ntawm 42% piv txog nkauj xwb pet3, nws lub zog tiag tiag hauv kev hloov pauv kev lag luam:

 

Kaw lub voj:Lub raj mis → SSP Pellet → Lub raj mis tshiab

 

Upcycling muaj peev xwm:Cov xim plaub ya ri, ib zaug pov tseg, tam sim no ua rau cov thawv opaque uas siv cov ntxhia cov ntxhitives (piv txwv li, callica lossis callica lossis callica lossis callica lossis callica lossis callica

 

Lub kauj ruam tsim:Hom zoo li puma thiab uniqlo tam sim no sib koom ua ke rpet rau hauv apparel thiab ntim - ast ast astating.

 

Txoj kev ua ntej

Cov kev sib tw: Sau cov txheej txheem kev tsim kho hauv kev tsim kev lag luam thiab thermal stability txwv rau kub {{sau fillo. Tsis tau muaj kev hloov kho zoo li cov tshuaj recycling (depolymerizing tsiaj rau nkauj xwb- qib monomers) hint ntawm kev daws teeb meem.

 

Raws li kev lag luam xws li Coca - Cola Party 50% RPet cov ntsiab lus li cas, qhov kev lag luam no tsis yog recesigning pov tseg lub luag haujlwm hauv peb lub neej yav tom ntej.
