Kutchuka ndi nkhawa za "mabotolo a PET"
"PET botolo" ndi mtundu wa chidebe chakumwa chomwe chagwiritsidwa ntchito kuyambira 1988 panthawi yamavuto amagetsi, pomwe Anthu anali kuganiza za zomwe zingagwiritsidwe ntchito kuchepetsa kugwiritsa ntchito mphamvu ndikusintha zitini zachitsulo zowononga mphamvu, zitini za aluminiyamu, ndi zitini zamagalasi. "Mabotolo a PET" ali ndi mawonekedwe a kulemera kopepuka, chitetezo, kupulumutsa mphamvu, komanso oyenera kugwiritsidwa ntchito kunyumba, motero adadziwika padziko lonse lapansi patangopita nthawi yochepa atagulitsidwa pamsika waku US mu 1989, ndipo amagwiritsidwa ntchito kwambiri. mu zakumwa, mowa ndi Packaging zipangizo za ukhondo.
"Mabotolo a PET" amapangidwa ndi polyethylene terephthalate, yomwe imadziwika kuti PET. "Mabotolo a PET" nthawi zonse amakhala ofunikira pakutolera zobwezerezedwanso. Ngakhale mabotolo a PET ndi otamandika chifukwa ndi opepuka komanso olimba koma samawonongeka mosavuta mwachilengedwe. Zimapangitsa kuti ngalande za ngalande zitsekedwe, zimapangitsa kukhalapo kwa zinyalala zazikulu komanso kukhala cholemetsa kwa chilengedwe. Akuluakulu a Chigawo cha China Taiwan adalengeza za kukhazikitsanso zinyalala zovomerezeka mu Novembala 1988, ndipo adavomereza bungwe la Environmental Protection Agency kuti likhazikitsenso kukonzanso zinyalala zochokera kuzinthu zinazake. Taiwan Environmental Protection Agency idalengeza za "PET botolo" zobwezeretsanso ndikuchotsa zinyalala mu June 1989.
Kubwezeretsanso botolo la PET ndi nsalu zobwezerezedwanso
Mabotolo a PET ndi opanda poizoni komanso opanda mpweya. Pakali pano, iwo sadzabala nkhosa. Ndi zabwino zopangira kuti zibwezeredwenso. Monga momwe akuchulukirachulukira, zinthu zobwezerezedwanso za PET zimaperekedwa ngati ulusi wosalukidwa, zipi, zodzaza ndi zina.
Kuphwanya njerwa za "botolo la PET" kukhala zidutswa ndikuzungulira, kenako "PET botolo" ulusi wobwezerezedwanso umapangidwa. "PET botolo" ulusi wobwezerezedwanso umalukidwa munsalu, yotchedwa "PET botolo loteteza chilengedwe". Chifukwa cha ubwino wake wa kukana abrasion, mayamwidwe chinyezi ndi permeability bwino, angagwiritsidwe ntchito pa masewera, zomangira nsapato, pamwamba, nsapato okwera, masutikesi, etc. "PET botolo" recycled silika regrown angagwiritsidwe ntchito kupanga zovala, zofunda, zipewa. , zipangizo za nsapato, matumba, mawigi, ndi zina zotero "PET botolo" zobwezerezedwanso ulusi waufupi wokhazikika ukhoza kupindika ndi kupota mu ulusi, kuwomba kapena kuluka mu nsalu, ndi kupanga zinthu zina zosiyanasiyana. Komanso, itha kugwiritsidwanso ntchito ngati padding zakuthupi, sanali nsalu nsalu zakuthupi, etc.
Kuchepetsa kuwonongeka kwa chilengedwe ndi gawo lomwe ochita bizinesi ayenera kuganizira pochita bizinesi. Kaya ikufufuza ndikupanga matekinoloje atsopano opulumutsa mphamvu kapena kugwiritsa ntchito zida zatsopano zomwe zingachepetse kuipitsidwa, tsopano ndi njira yachitukuko yomwe makampani angachite.
Nsalu zobwezerezedwanso zoyimilira ku Taiwan China
Pakadali pano, 100% yazinthu zobwezerezedwanso zitha kubwezerezedwanso kukhala ulusi wa PET. Pali opanga 5 akuluakulu a "botolo la PET" ku Taiwan, mafakitale opitilira 10 omwe amagwiritsa ntchito mabotolo a PET obwezeretsedwanso, komanso opanga nsalu ndi zovala opitilira 100.
Taiwan Xianyu Enterprise Co., Ltd. idakhazikitsa nsalu yothandiza zachilengedwe ECO GREENR mu 2007, yomwe ndi "botolo la PET" lopangidwanso ndi CHIKWANGWANI. Kampaniyo ikukhulupirira kuti iyenera kunyamula maudindo oterowo, ndikukhazikitsa zikhulupiriro zotere pazolinga zamakampani. Nsalu yoteteza zachilengedwe ECO GREENR imayimira chikhalidwe chamakampani cha kampani chomwe chimayamikira kuteteza chilengedwe.
Nsalu ya ECO GREEN imagwiritsa ntchito ulusi wa PET wopangidwanso ndi botolo la PET wopangidwa ndi Taiwan Zhongxing Textile Company (dzina lazinthu zolembetsedwa ndi GREEN PLUS R). Mfundo yobwezeretsanso ndikutsuka, kung'amba, kusungunula zinyalala "mabotolo a PET", kenako ndikutulutsa. Mlingo wosinthika umaposa 90%. Kilogalamu imodzi ya "botolo la PET" ikufanana ndi malita 0,8 amafuta osakanizidwa. Ndiko kunena kuti, kugwiritsa ntchito "botolo la PET" kukonzanso ulusi wa polyester osati kungochotsa zinyalala za "botolo la PET", komanso kuchepetsa kugwiritsa ntchito mafuta. Kuphatikiza apo, malinga ndi Zhongxing Textile Company, mphamvu (kuphatikiza zinthu zopangira, mafuta, madzi, magetsi, ndi zina) zomwe zimagwiritsidwa ntchito popanga "mabotolo a PET" kuti azibwezeretsanso ulusi wa poliyesitala ndi 80% yocheperako kuposa ulusi wa poliyesitala wopangidwa kuchokera kumafuta opanda mafuta.
Woyimilira kwambiri ku Taiwan ndi TEXCARE Fiber. ulusi wochezeka wachilengedwe uwu umapangidwa kudzera mu njira yachiwiri ya polymerization. Ndiko kuti, pogwiritsa ntchito mankhwala obwezeretsanso. Ulusiwu umapangidwa kuchokera ku zinyalala za "botolo la PET" ndi nsalu zosweka za polyester, ulusi ndi mafilimu. Iwo poyamba amawonongeka ndi mankhwala. Pambuyo pakuwonongeka, ma monomers amatsukidwa ndikukonzedwa, ndiyeno EG ndi DMT zimachitanso kuti zipange zida zoyambira za polyester. Chifukwa chake, kuyera kwa zinthu zobwezerezedwanso za poliyesitala zopangidwa ndi Haojie ndizazikulu kuposa zomwe zimapangidwiranso poliyesitala. Chakwera kuchoka pa 90% kufika pafupifupi 100%.
Taiwan Shibao yakhala ikupanga "PET botolo" yobwezeretsanso mitundu ya nsalu za fiber kwa zaka 20, ndipo akukumana ndi zovuta zambiri komanso zopinga pakupanga chitukuko. Koma kampaniyo nthawi zonse imatsatira udindo wake wamagulu monga udindo wake ndikugonjetsa zovuta zingapo. Pakhala zopambana m'madera ambiri mpaka pano. Monga:
a.Limbikitsani mosalekeza kuzindikira kwa malingaliro oteteza chilengedwe, kuti ogula azitha kuvomereza zinthu zachilengedwe komanso zachilengedwe zomwe zili ndi mitengo yokwera;
b.Ubwino wa "botolo la PET" wopangidwanso ndi ulusi wopangidwanso ndi wokhazikika komanso wofanana ndi ulusi woyambirira;
c."PET botolo" filament imagulitsidwa pang'onopang'ono;
d.Kuthamanga kwamtundu wa "PET botolo" wobwezerezedwanso utoto wa fiber ku kuwala kwa dzuwa kumaposa mlingo 4;
e. "Pote PET botolo" nsalu CHIKWANGWANI chimatha kukonzedwa zosiyanasiyana pambuyo pomaliza processing kukwaniritsa zofunika zosiyanasiyana ntchito;
f. Kuteteza zachilengedwe kungathe kuchepetsa kulemetsa kwa chilengedwe;
g. Wonjezerani mitundu yosiyanasiyana ya nsalu zobwezerezedwanso za "mabotolo a PET", monga zovala zakunja, zovala zamasewera, zovala zamkati, zikwama, zinthu zapakhomo, ndi zina zambiri.
Kuchita ndi mtundu wa nsalu za LIBOLONR za Li Peng zili patsogolo pa zinthu zomwezi padziko lapansi. Pofuna kuteteza chilengedwe komanso kupindula ndi chilengedwe chokongola cha mibadwo yamtsogolo, LIBOLON yapanga mndandanda wazinthu zachilengedwe zachilengedwe monga RePETTM, RePETTM-solution ndi Ecoya" m'zaka zaposachedwa.
RePET TM ndi mtundu wa "Botolo la Pote PET" lopangidwanso ndi fiber, ndipo yankho la RePETM ndilopangidwanso ndi PET ulusi wopangidwa ndi kusungunula ulusi wotayidwa, kotero kuti sufunika kupakidwa utoto, motero umakhala wokonda zachilengedwe kuposa RePETTM. Kufunika kwake kwakukulu ndikuti sikungochepetsa mpweya wobiriwira wa nyumba ndi zinyalala zambiri zomwe zimawononga okosijeni, komanso zimachepetsa kumwa madzi komanso kugwiritsa ntchito mankhwala. Onse a RePET TM ndi RePET TM-solu-tion apeza chiphaso chachitetezo cha chilengedwe cha Taiwan chobiriwira chobiriwira chachilimwe.
EcoyaTM ndi ulusi wopaka utoto. Njira zambiri zopaka utoto zimatha kusiyidwa, ndipo utoto umatha ndikuwonjezera kusungunuka kwa polima silika isanapangidwe. Malingana ndi ziwerengero: ngati bio-textiles idzalowetsedwa ndi Ecoy aTM, CO2 ndi COD zotulutsa mpweya zidzachepetsedwa kwambiri, ndipo madzi ndi mankhwala akhoza kusungidwa. Mwachiwonekere, njira iyi yopangira utoto wa ulusi ndi wokonda zachilengedwe.
Ecoya TM ili ndi zinthu zambiri zabwino kwambiri pamtundu wachangu ku kuwala kwa dzuwa, kuthamanga kwa mtundu kumadzi, kuthamanga kwa mtundu kuchapa, kukana kwa UV ndi kuberekana kwamtundu.
Kampani ya Heyou inali ndi projekiti yobiriwira "CYCLEPET", yomwe imagwiritsa ntchito zida zobwezerezedwanso kuchokera ku "mabotolo a PET" kupanga nsalu zoteteza zachilengedwe komanso zachilengedwe zomwe zimatha kuteteza mphamvu. Ikhoza kupereka ntchito zosiyanasiyana, monga: kuchokera ku zovala kupita ku katundu wa katundu , Ku ntchito za mafakitale ndi mitundu ina, monga mitundu yosiyanasiyana ya flannel, nsalu zoluka ndi zoluka, maukonde (maukonde apakamwa ndi maukonde odzipatula) ndi zina zotero.
