2, Dab tsi yog qhov txawv ntawm cov thawv ntim khoom noj su thiab hnab yas pov tseg? Txawm hais tias ob hom khib nyiab yog cov khib nyiab rov ua dua los tsis yog ...
1. Cov thawv noj su thiab hnab yas pov tseg yog cov khib nyiab rov ua dua
Raws li kev lag luam tus qauv ntawm "Kev faib tawm thiab Kev Ntsuam Xyuas Cov Khoom Siv Hauv Nroog" thiab nrog rau kev siv txoj cai lij choj German khib nyiab cais, cov khoom siv rov ua dua tau xa mus rau cov khib nyiab uas tsim nyog rau kev rov ua dua tshiab, rov ua dua tshiab thiab siv cov peev txheej. Feem ntau suav nrog ntawv, yas, hlau, iav, textile.
Plastics feem ntau muaj xws li: khib nyiab ntim yas, ntim yas thiab lwm yam khoom yas. Xws li ntau lub hnab yas, lub raj mis yas, ua npuas ncauj yas, cov hnab yas pov tseg thiab cov tais diav, cov yas tawv, thiab lwm yam.
Qhov thib ob, qhov sib txawv tseem ceeb ntawm cov thawv ntim khoom noj su thiab hnab yas pov tseg
(1) Cov khoom tseem ceeb sib txawv
(1) Disposable su box
Cov khoom xyaw tseem ceeb: yas, ntawv, hmoov txhuv nplej siab, tsis tshua muaj hlau.
(2), hnab yas
Cov khoom tseem ceeb: polypropylene, polyester, nylon, thiab lwm yam.
(2), cov yam ntxwv sib txawv
(1) Disposable su box
Cov thawv ntim khoom noj ceev uas siv tau pov tseg tau hloov pauv los ntawm cov thawv ntim khoom noj khoom haus mus rau ib puag ncig tus phooj ywg noj su. Thawj lub thawv ntim khoom noj tau raug tshem tawm vim tias lawv tsis tiv taus qhov kub thiab txias thiab ua rau muaj kev puas tsuaj rau ib puag ncig thaum lub sijhawm tsim khoom. Cov thawv ntim khoom noj khoom haus, cov thawv ntawv noj su, cov thawv noj su ntoo, thiab cov thawv noj su uas degradable tau hloov. Thiab lwm yam. Ntawm lawv, yas muaj cov yam ntxwv ntawm cov tshuaj lom neeg tsawg, siab melting point, muaj zog plasticity, yooj yim ntau lawm thiab tus nqi qis, yog li nws tau dhau los ua cov khoom tseem ceeb rau kev tsim cov khoom noj txom ncauj pov tseg.
①, polyethylene zaj duab xis (tsis muaj tshuaj lom)
Cov zaj duab xis yog milky dawb thiab translucent (nws yog tshwj xeeb tshaj yog pom tseeb thaum ob peb txheej yog stacked), nws yog du rau kov, zoo li yog hais tias muaj ib tug ciab txheej nyob rau saum npoo, co nrog quab yuam, lub suab yog nkig, flammable nyob rau hauv cov ntaub ntawv ntawm ib tug wax txheej. hluav taws kub, nplaim taws yog daj, thiab muaj nplaum nplaum thaum kub hnyiab, thiab tsw ntxhiab tsw tswm ciab.
②, polyvinyl chloride zaj duab xis (feem ntau tshuaj lom)
Yog tias tsis muaj xim ntxiv, nws yog pob tshab, qhov saum npoo yog nplaum rau qhov kov, shakes vigorously, lub suab qis, thiab nws tsis yooj yim rau hlawv thaum hluav taws.
(1) Disposable su box
Disposable expanded plastic su boxes tseem hu ua disposable expanded polystyrene snack boxes. Ntawm lawv, polystyrene yog siv los ua raw khoom. Yog tias dawb monomer styrene nyob rau hauv nws cov khoom raug tso tawm los ntawm tshav kub thiab nkag mus rau tib neeg lub cev nrog zaub mov, nws yuav muaj qee yam kev puas tsuaj rau lub hauv paus paj hlwb, ob lub raum, thiab daim siab, thiab txawm ua rau mob qog noj ntshav. Yog li ntawd, kev siv mus sij hawm ntev yuav ua rau muaj kev pheej hmoo ntawm kev mob. .
(2), hnab yas
Kev rov ua dua tshiab ntawm cov hnab yas yog tsawg, thiab ntxiv rau qhov ua rau pom kev ua qias tuaj hauv nroog txoj kev, cov chaw ncig tebchaws, cov dej hauv dej, thiab ob sab ntawm txoj kev thiab kev tsheb ciav hlau, muaj peev xwm ua rau muaj kev phom sij thaum siv. Cov qauv yas yog ruaj khov, tsis yooj yim rau degraded los ntawm tej yam ntuj tso microorganisms, thiab yuav tsis raug cais nyob rau hauv ib puag ncig ntuj. Qhov no txhais tau hais tias yog cov khib nyiab pov tseg yas tsis rov siv dua, nws yuav dhau los ua cov pa phem hauv ib puag ncig thiab khaws cia ntev, uas yuav ua rau muaj kev puas tsuaj loj rau ib puag ncig.

Classification txoj cai:
1. Faib thiab siv nws
Lub hom phiaj ntawm kev faib tawm yog hloov cov pov tseg rau kev kho mob, siv lub peev xwm tsim khoom uas twb muaj lawm, rov ua dua cov khoom siv rov ua dua tshiab, suav nrog kev siv cov khoom siv thiab kev siv hluav taws xob, thiab kev pov tseg pov tseg kom pov tseg cov khib nyiab tsis muaj txiaj ntsig uas tsis muaj ib ntus.
2. Kho cov kev ntsuas rau hauv zos
Lub geography ntawm txhua lub koog tsev kawm ntawv, txhua lub koog tsev kawm ntawv, txhua lub zej zog (koog tsev kawm ntawv), txhua lub zej zog, theem ntawm kev loj hlob ntawm kev lag luam, kev muaj peev xwm ntawm kev lag luam rov ua dua pov tseg, qhov chaw ntawm cov neeg nyob hauv, kev ua neej nyob, kev khwv nyiaj txiag thiab kev puas siab puas ntsws, thiab lwm yam txawv.
3. Kev tswj hwm tus kheej
Cov zej zog thiab cov neeg nyob hauv, suav nrog cov tuam txhab thiab cov tsev kawm ntawv, tau maj mam tsim cov cai ntawm "txo, rov ua dua tshiab, kev paub txog tus kheej, thiab kev tswj hwm tus kheej", tsim kho cov qauv kev faib tawm thiab kev kho cov khib nyiab, thiab dhau los ua lub zog tseem ceeb hauv kev txo cov khib nyiab, kev faib tawm, rov ua dua tshiab. thiab kev siv.
