Hom Plastics siv nyob rau hauv Recycling

Cov yas tau muab faib ua ntau hom, txhua tus txheeb xyuas los ntawm kev txheeb xyuas cov lej. Cov hom muaj xws li:

1. PET (Polyethylene Terephthalate): Siv hauv cov fwj dej thiab ntim khoom noj.

2. HDPE (High-Density Polyethylene): Pom nyob rau hauv cov tshuaj ntxuav tais diav thiab cov hnab ntim khoom noj.

3. PVC (Polyvinyl Chloride): Siv nyob rau hauv cov kav dej thiab cov qhov rais thav duab.

4. LDPE (Low-Density Polyethylene): Cov khoom siv rau cov hnab ntim khoom thiab cov thawv ntim tau yooj yim.

5. PP (Polypropylene): Siv rau hauv cov khoom siv tsheb thiab cov thawv ntim khoom.

6. PS (Polystyrene): Pom nyob rau hauv cov khoom siv pov tseg thiab ua npuas ncauj ntim.

Sau thiab Sorting

Cov yas rov ua dua tshiab pib nrog kev sau, uas tshwm sim los ntawm cov kev pab cuam curbside, cov chaw tso tawm, thiab cov txheej txheem tso nyiaj / rov qab. Tom qab sau, cov ntaub ntawv raug xa mus rau Material Recovery Facilities (MRFs) qhov twg lawv tau txheeb los ntawm hom thiab xim. Advanced technologies xws li ze-infrared sensors thiab AI systems txhim khu kev ua tau zoo thiab qhov tseeb ntawm cov txheej txheem sorting no.

Ntxuav thiab txiav

Thaum txheeb xyuas, cov yas raug ntxuav kom tshem tawm cov impurities xws li cov khoom seem, cov nplaum, thiab cov ntawv lo. Tom qab ntawd cov yas ntxuav tau muab txiav rau hauv cov flakes me me los yog chips, npaj lawv rau kev ua haujlwm ntxiv. Cov theem no yog qhov tseem ceeb rau kev ua kom huv si ntawm cov khoom siv rov ua dua tshiab, uas ua rau muaj kev cuam tshuam rau qhov zoo ntawm cov khoom kawg.

Kev txheeb xyuas thiab kev faib tawm

Thaum ua tiav, nws yog ib qho tseem ceeb los txheeb xyuas thiab faib cov hom yas kom raug. Cov txheej txheem xws li kev sib cais ceev thiab kev tsom xam spectral yog siv los xyuas kom meej tias tsuas yog cov yas sib xyaw ua ke thaum lub sij hawm melting. Kev tsis pom zoo tuaj yeem ua rau cov khoom siv tsis zoo.

Reprocessing rau hauv Raw Material

Cov yas shredded yog yaj thiab hloov dua siab tshiab rau hauv pellets, uas tuaj yeem siv los tsim cov khoom tshiab. Qhov kev hloov pauv no feem ntau yog ua los ntawm cov txheej txheem xws li extrusion thiab pelletizing. Cov pellets rov ua dua no tau muab tso rau hauv kev tsim khoom tshiab, kaw lub voj rov ua dua tshiab.

Lub luag hauj lwm ntawm Recycled Plastics nyob rau hauv Manufacturing

Cov yas rov siv dua yog siv ntau yam khoom, los ntawm kev ntim khoom thiab khaub ncaws mus rau cov khoom siv. Kev siv cov khoom siv rov ua dua tshiab pab cov tuam txhab txo cov nqi tsim khoom thiab kev cuam tshuam ib puag ncig. Tsis tas li ntawd, nws pab txhawb kev lag luam ncig, txhawb kev siv peev txheej.

Xaus

Kev nkag siab txog cov txheej txheem rov ua dua tshiab yog qhov tseem ceeb rau kev txhim kho kev coj noj coj ua thoob ntiaj teb. Los ntawm kev txhim kho kev siv thev naus laus zis thiab kev tsim kho vaj tse thiab txo kev sib kis, peb tuaj yeem ua kom muaj txiaj ntsig zoo ntawm cov yas rov ua dua tshiab. Nws yog ib qho tseem ceeb rau cov neeg siv khoom, kev lag luam, thiab tsoomfwv los koom tes hauv kev txhawb nqa cov kev coj ua zoo dua qub kom ntseeg tau tias yav tom ntej ntsuab.
