Cov yas virtual xa mus rau cov khoom lag luam- cov yas tshiab tsim los ntawm cov khoom siv raw xws li roj av thiab cov nkev roj los ntawm cov txheej txheem tshuaj lom neeg. Lawv yog cov khoom siv dawb huv, tsis tau siv txij thaum pib. Recycled plastics, ntawm qhov tod tes, yog cov yas tau los ntawm kev rov ua dua thiab ua cov khoom pov tseg yas. Vim tias lawv tau dhau los siv thiab rov ua dua tshiab, lawv txawv ntawm cov yas yas hauv qee txoj kev. Qhov sib txawv ntawm cov yas yas thiab cov yas rov ua dua tshiab tuaj yeem ua tau los ntawm cov hauv qab no.
I. Hais txog Kev Pom Zoo
1. Xim:
Virgin plastics feem ntau muaj cov xim ci dua, zoo ib yam. Siv cov yeeb yaj kiab yas ua piv txwv, cov yeeb yaj kiab nkauj xwb polyethylene zoo li ci, pob tshab, thiab xim ntshiab. Qhov no yog vim hais tias cov khoom siv raw yog cov ntshiab thiab raug tswj xyuas nruj thaum lub sijhawm tsim khoom, ua rau muaj xim ntshiab hauv cov khoom tiav. Recycled plastics, vim lawv lub hauv paus chiv keeb, tej zaum yuav yog ib qho sib xyaw ntawm ntau yam xim thiab cov ntaub ntawv ntawm cov khoom pov tseg. Tom qab rov ua dua, lawv cov xim feem ntau tsaus dua, tsis sib xws, thiab tej zaum yuav muaj impurities lossis me ntsis. Piv txwv li, cov thoob yas rov ua dua tshiab yuav muaj xim ntau dua li cov thoob yas yas, thiab lub thoob lub cev yuav muaj xim sib txawv.
2. Pob tshab:
Virgin plastics muaj qhov pom tseeb, tshwj xeeb tshaj yog qee lub thawv yas siv rau ntim khoom noj, xws li cov raj mis yas PET. Cov ntsiab lus hauv yog pom meej meej, nrog lub pob tshab mus txog ntawm iav. Qhov no yog vim lawv cov txheej txheem tsim khoom ruaj khov thiab cov qauv molecular tsis tu ncua. Cov khoom siv rov ua dua tshiab, thaum lub sijhawm rov ua dua tshiab, muaj lawv cov molecules puas thiab lawv txoj kev teeb tsa tsis zoo, ua rau feem ntau tsis pom kev. Txawm hais tias nrog tib lub raj mis yas PET, yog tias nws rov ua dua, cov ntsiab lus yuav pom qhov muag plooj thaum pom los ntawm sab nraud.
3. Nto Smoothness:
Virgin plastics muaj qhov du, tiaj tus thiab muaj kev xav zoo. Piv txwv li, nkauj xwb polypropylene yas tableware zoo nkaus li nyob rau hauv kev ntxhib los mos, tsis muaj roughness. Qhov no yog vim cov txheej txheem molding siv cov cuab yeej siv siab heev thiab ib puag ncig zoo. Cov khoom siv rov ua dua tshiab, vim tias muaj peev xwm hnav thiab muaj paug ua ntej rov ua dua tshiab, thiab qhov nyuaj ntawm kev tshem tawm cov impurities thaum ua tiav, feem ntau muaj qhov rougher nto, thiab tej zaum yuav muaj me me los yog khawb. Piv txwv li, cov khoom ua si yas rov siv dua yuav muaj qhov tsis sib xws.
4. tsw:
Virgin plastics feem ntau tsuas muaj me ntsis, yam ntxwv tsw ntxhiab, lossis yuav luag tsis muaj ntxhiab tsw. Virgin polyethylene yas, siv los ua cov zaj duab xis cling, tsis tshua muaj ntxhiab tsw tom qab qhib lub ntim. Qhov no yog vim hais tias cov additives thiab lwm yam khoom siv nyob rau hauv zus tau tej cov yas yas yog siv raws li cov kev cai thiab raug soj ntsuam nruj zoo. Cov khoom siv rov ua dua tshiab, ntawm qhov tod tes, tuaj ntawm ntau qhov chaw pov tseg yas thiab tej zaum yuav tau nkag mus rau ntau yam khoom. Thaum lub sij hawm reprocessing, tshuaj tej zaum yuav tshwm sim, feem ntau ua rau ib tug pungent thiab complex tsw. Piv txwv li, qee cov kav dej yas rov ua dua tshiab yuav muaj qhov tsis hnov tsw tsw zoo ib yam li tshuaj lom neeg lossis cov khib nyiab thaum tsw zoo.
II. Hais txog kev ua haujlwm
1. Lub zog:
Virgin plastics muaj lub cev ruaj khov thiab lub zog siab. Siv cov kav dej nkauj xwb PPR ua piv txwv, lawv tuaj yeem tiv taus siab dua yam tsis muaj kev tawg yooj yim thiab tuaj yeem lav tau ntev - cov dej xa dej raws li kev siv ib txwm muaj. Qhov no yog vim hais tias cov saw hlau molecular ntawm cov yas yas tsis zoo, thiab lub zog ntawm lub cev muaj zog. Cov khoom siv rov ua dua tshiab, txawm li cas los xij, muaj lawv cov saw hlau molecular puas thiab lawv cov qauv molecular hloov pauv thaum lub sijhawm rov ua dua tshiab, ua rau muaj kev poob qis hauv lub zog. Rov ua dua PPR cov kav dej ntawm tib qhov kev qhia tshwj xeeb tuaj yeem tawg lossis txawm tias tawg nyob rau hauv qhov tsis tshua muaj siab.
2. Flexibility:
Virgin plastics muaj qhov yooj yim dua. Piv txwv li, nkauj xwb PE hnab yas tau yooj yim folded thiab stretched yam tsis tau tawg yooj yim. Qhov no yog vim lawv cov qauv molecular zoo thiab cov khoom. Recycled plastics, ntawm qhov tod tes, muaj kev hloov pauv tsis zoo. Tom qab ntau cov kauj ruam ua, cov elasticity ntawm cov yas txo qis, ua rau nws tawv. Cov hnab khib nyiab PE rov siv dua, piv txwv li, tsim kua muag yooj yim yog rub tawm thaum siv.
3. Thaum tshav kub kub Resistance:
Virgin plastics muaj qhov ua tau zoo thaum tshav kub kub, tswj kev ua haujlwm ruaj khov hauv qee qhov kub thiab txias. Piv txwv li, Virgin PC yas khob dej feem ntau tsis deform lossis tso cov khoom tsis zoo thaum ntim dej kub. Cov khoom siv rov ua dua tshiab, vim lawv txoj kev sib xyaw ua ke thiab muaj peev xwm raug rau qhov kub thiab txias thaum rov ua dua, tau txo qhov kub tsis kam. Lub khob dej rov qab rau PC ua los ntawm cov khoom qub tuaj yeem muag thiab deform thaum sau nrog dej sov me ntsis.
Los ntawm kev sib piv cov tsos, tsw, thiab kev ua tau zoo, ib tus tuaj yeem paub qhov txawv ntawm cov nkauj xwb thiab cov khoom siv rov ua dua tshiab rau qee yam.
