Wood-plastiki, inozivikanwawo sehuni dzekuchengetedza zvakatipoteredza, huni dzepurasitiki uye huni dzerudo, dzinonzi "WPC" pasi rose.Yakagadzirwa muJapan muhafu yechipiri yezana ramakore rapfuura, imhando nyowani yezvakasanganiswa zvinhu zvakagadzirwa nesawdust, sawdust, bamboo machipisi, goko remupunga, uswa hwegorosi, soya bhinzi, deko renzungu, bagasse, donje uswa uye humwe kukosha kwakaderera. biomass fibers.Iyo ine mabhenefiti ezvese chirimwa fiber uye epurasitiki, uye ine huwandu hwakasiyana hwekushandisa, inovhara dzinenge dzese minda yekushandisa yematanda, mapurasitiki, epurasitiki simbi, aruminiyamu alloys uye zvimwe zvakafanana zvinoumbwa zvinhu.Panguva imwecheteyo, inogadzirisawo dambudziko rekudzokororwa kwezviwanikwa zvemarara mumapurasitiki nemaindasitiri emapuranga pasina kusvibiswa.Hunhu hwayo hukuru ndeiyi: kushandiswa kwezviwanikwa zvezvakagadzirwa, plasticization yezvigadzirwa, kuchengetedza kwezvakatipoteredza mukushandiswa, mutengo wehupfumi, kudzokorodza uye kudzokorodza.
China inyika ine zviwanikwa zvemasango zvisina kunaka, uye masango ega ega ari pasi pe10m³, asi kushandiswa kwehuni pagore muChina kwakakwira zvakanyanya.Maererano nenhamba dzepamutemo, chiyero chekukura kwehuni muChina chakaramba chichiwedzera kuwedzera kweGDP, kusvika ku 423 mamiriyoni cubic metres muna 2009. Nekuvandudzwa kwehupfumi, kushayikwa kwehuni kuri kuramba kuchiwedzera.Panguva imwecheteyo, nekuda kwekuvandudzwa kwedanho rekugadzira, marara ekugadzira huni senge sawdust, shavings, marara epakona uye huwandu hukuru hwemafibhi ezvirimwa senge huswa, hundi yemupunga uye mateko emichero, ayo aimboshandiswa sehuni mumoto. zvakapfuura, zvakaraswa zvakakomba uye zvine simba rinoparadza rakakura pane zvakatipoteredza.Maererano nenhamba, uwandu hwemarara anosiiwa nekugadzirwa kwehuni muChina hunodarika matani mamiriyoni anoverengeka gore negore, uye uwandu hwedzimwe shinda dzinongoitika dzoga dzakadai sehundi yemupunga makumi emamiriyoni ematani.Mukuwedzera, kushandiswa kwezvigadzirwa zvepurasitiki kunowedzera kuwedzera nekuvandudzwa kwehupfumi hwemagariro evanhu, uye dambudziko re "kusvibiswa kwakachena" kunokonzerwa nekurapwa kusina kunaka kwemarara epurasitiki rave dambudziko rakaoma mukuchengetedzwa kwezvakatipoteredza.Yakakodzera ongororo data inoratidza kuti marara epurasitiki anotora 25% -35% yehuwandu hwemarara emadhorobha, uye muChina, huwandu hwepagore hwemaguta hunogadzira 2.4-4.8 miriyoni matani emarara epurasitiki.Kana zvinhu izvi zvinoraswa zvikashandiswa zvinobudirira, zvinounza zvikomborero zvikuru zvehupfumi nemagariro.Wood-plastiki zvinhu chinhu chitsva chakaumbwa chakagadzirwa kubva mumarara.
Nekusimbaradzwa kwekuziva kwevanhu nezvekuchengetedzwa kwemhoteredzo, kudana kwekuchengetedza zviwanikwa zvemasango uye kuderedza kushandiswa kwehuni hutsva kuri kuwedzera uye nenzwi guru.Kudzokorodza marara ematanda nemapurasitiki ane mutengo wakaderera kwave kunetsa muindasitiri nesainzi, izvo zvakasimudzira nekusimudzira tsvakiridzo nekuvandudzwa kwehuni-plastiki composites (WPC), uye yakafambira mberi zvakanyanya, uye kushandiswa kwayo kwakaratidzawo kukurumidza kusimudzira. trend.Sezvatinoziva tose, tsvina yehuni uye fiber yekurima inogona kupiswa chete zvisati zvaitika, uye carbon dioxide inogadzirwa ine greenhouse effect panyika, saka miti yekugadzira huni iri kuedza kutsvaga nzira dzekuishandura kuita zvigadzirwa zvitsva zvine kukosha kwakawedzerwa.Panguva imwecheteyo, kudzokorodza kwepurasitiki ndiyowo nzira yakakosha yekuvandudza tekinoroji yeindasitiri yepurasitiki, uye kuti purasitiki inogona kudzokororwa here kana kuti kwete yave imwe yehwaro hwakakosha hwekusarudzwa kwezvinhu mumaindasitiri mazhinji ekugadzira epurasitiki.Muchiitiko ichi, maumbirwo emapuranga-epurasitiki akatanga, uye hurumende nemadhipatimendi akakodzera pasi rose vakateerera zvikuru kukudziridzwa uye kushandiswa kwechinhu chitsva ichi chinochengetedza zvakatipoteredza.Wood-plastic composite inobatanidza zvakanakira huni uye plastiki, iyo isina kungoita seyakasikwa huni, asiwo inokunda kukanganisa kwayo.Iyo ine zvakanakira corrosion resistance, hunyoro kuramba, kudzivirira moth, high dimensional kugadzikana, hapana kutsemuka uye hapana warping.Iine kuoma kwepamusoro pane epurasitiki yakachena, uye ine processability yakafanana nehuni.Inogona kutemwa uye kusungirirwa, yakagadziriswa nembambo kana mabhoti, uye pendi.Imhaka yekuti mabhenefiti maviri emutengo uye kuita kuti matanda-epurasitiki macomposites ave achiwedzera minda yavo yekushandisa uye kupinda mumisika mitsva mumakore achangopfuura, achiwedzera kutsiva zvimwe zvechinyakare.
Nekuedza kwakabatana kwemapato ese, huwandu hwekugadzira mudzimba hwehuni-plastiki zvinhu / zvigadzirwa zvakasvetukira kumberi kwenyika, uye yakawana kodzero yekuve nenhaurirano yakaenzana nemabhizinesi emapuranga-plastiki munyika dzakabudirira muEurope uye. America.Nekusimudzirwa kwakasimba kwehurumende uye kuvandudzwa kwemafungiro emagariro evanhu, huni-plastic industry ichawedzera kupisa uye kupisa sezvainokura.Kune makumi ezviuru zvevashandi muindasitiri yehuni-plastiki yeChina, uye kugadzirwa kwepagore uye kutengesa kwezvigadzirwa zvehuni-purasitiki kuri pedyo ne100,000 matani, nemutengo wepagore wekubuda unopfuura 800 miriyoni yuan.Mabhizinesi emapuranga-epurasitiki akatarisana muPearl River Delta neYangtze River Delta, uye chikamu chekumabvazuva chinodarika nzvimbo dzepakati nekumadokero.Iyo tekinoroji nhanho yemabhizinesi ega ega kumabvazuva iri mberi, nepo mabhizinesi ari kumaodzanyemba aine mabhenefiti akakwana muhuwandu hwechigadzirwa uye musika.Iwo masampula ebvunzo emabhizinesi akakosha esainzi uye tekinoroji anomiririra muindastiri asvika kana kupfuura pasi rose.Mamwe mabhizinesi makuru uye mapoka emarudzi akawanda ari kunze kweindasitiri ari kutarisisawo kusimudzira kweindasitiri yehuni-plastiki muChina.
