China inokamura machira emumaindasitiri muzvikamu gumi nematanhatu, uye parizvino machira asiri akarukwa anotora chikamu mumapoka mazhinji, akadai sekurapa, hutano, kuchengetedza kwezvakatipoteredza, geotechnical, kuvaka, mota, zvekurima, maindasitiri, chengetedzo, ekugadzira matehwe, kurongedza, fenicha, mauto, zvichingodaro. Pakati pavo, machira asiri akarukwa akatotora chikamu chikuru uye akashandiswa zvakanyanya muminda yakadai sehutsanana, kusefa kwezvakatipoteredza, kuvaka geotechnical, dehwe rekugadzira, mota, maindasitiri, kurongedza, uye fenicha. Mune zvekurapa, zvekurima, canopy, zvekudzivirira, zvechiuto nemimwe minda, ivo vasvikawo kune imwe musika wekupinda mwero.
Utsanana zvinhu
Zvishandiso zvehutsanana zvinonyanya zvinosanganisira manapukeni uye ma napkins ehutsanana ekushandiswa kwezuva nezuva nevakadzi nevacheche, zvigadzirwa zvekusagadzikana kwevanhu vakuru, mapepi ekuchengeta vana, mapepi emumba uye neruzhinji, mapepi ekunyorova ekubika, nezvimwewo. Manapukeni ehutsanana evakadzi ndiwo anokurumidza kukura uye anonyanya kushandiswa zvigadzirwa zvehutsanana muChina. Kubva kutanga kwema1990, kukurumidza kwavo kwekusimudzira kwave kunoshamisa. Pakazosvika 2001, chiyero chavo chekupinda mumusika chaive chapfuura 52%, nekushandiswa kwe33 bhiriyoni zvimedu. Zvinotarisirwa kuti muna 2005, chiyero chavo chekupinda mumusika chichasvika 60%, nekushandiswa kwezvikamu zve 38.8 bhiriyoni. Nekuvandudzwa kwayo, jira rayo, chimiro, uye zvakavakwa-mukati-zvinopinza zvinhu zvakachinja shanduko. Iyo jira uye mativi e-anti-seepage zvikamu zvinowanzo shandisa mhepo inopisa, inopisa rolling, yakanaka denier spunbond nonwoven machira, uye SM S (spunbond/meltblown/spunbond) zvinhu zvinoumbwa. Iyo yemukati inopinza zvinhu zvakare inoshandisa zvakanyanya pulp mhepo inoyerera ichigadzira Ultra-yakaonda zvinhu zvine SAP superabsorbent polymers; Kunyange zvazvo chiyero chekupinda mumusika chevanapukeni chichiri chakaderera, chakawanawo kukura kwakakosha mumakore achangopfuura; Nekudaro, mukurumbira wezvigadzirwa zvevakuru zvekusagadzikana, zvekupukuta zvekuchengeta vana, imba uye nzvimbo yeruzhinji yekuchenesa mapepi, nezvimwewo hazvina kukwirira muChina, uye vamwe vagadziri vemachira asina spunlace vanogadzira spunlace wipes kunyanya kutengeswa kunze kwenyika. China ine vanhu vakawanda uye kuwanda kwezvinhu zvehutsanana kuchiri kwakaderera. Nekumwe kuvandudzwa kwedanho rehupfumi hwenyika, munda uyu uchave mumwe wemisika mikuru yezvinhu zvisina kuruka muChina.
Mishonga yekurapa
Izvi zvinonyanya kureva akasiyana machira uye asiri akarukwa fiber zvigadzirwa zvinoshandiswa muzvipatara, senge machira ekuvhiya, makepisi ekuvhiya, masks, mavharo ekuvhiya, mavhavha eshangu, machira evarwere, zvemibhedha, gauze, mabhandeji, mapfekero, matepi, zvivharo zvemidziyo yekurapa, nhengo dzemunhu dzekugadzira, zvichingodaro. Mundima iyi, machira asiri akarukwa anoita basa rakanyanyisa mukudzivirira mabhakitiriya uye kudzivirira kutapukira. Nyika dzakasimukira dzine chikamu chemusika chisina kurukwa che70% kusvika 90% muzvigadzirwa zvemachira ekurapa. Nekudaro, muChina, kunze kwenhamba diki yezvigadzirwa zvakaita semajasi ekuvhiya, masiki, mavharo eshangu, uye matepi akagadzirwa nemucheka we spunbond, kushandiswa kwezvinhu zvisina kurukwa zvemachira hazvisati zvapararira. Kunyangwe izvo zvisiri zvakarukwa zvekuvhiya zvigadzirwa zvakashandiswa zvine gap rakakura mukushanda uye giredhi zvichienzaniswa nenyika dzakabudirira. Semuyenzaniso, magauni ekuvhiya munyika dzakasimukira dzakadai seEurope neAmerica anowanzo shandisa akasununguka kupfeka uye kuva neakanaka mabhakitiriya uye kudzivirira ropa zvinhu, senge SM S inoumbwa zvinhu kana hydroentangled isina-yakarukwa zvinhu.
Zvisinei, muChina, jira re spunbond uye firimu repurasitiki rinosanganiswa zvipfeko zvekuvhiya zvinonyanya kushandiswa, uye SM S haisati yave yakagamuchirwa zvakanyanya; Iyo yakawanda inoshandiswa hydroenangled isiri-yakarukwa mabhandiji, gauze, uye hydroenangled ekuvhiya drapes yakasanganiswa nehuni pulp munyika dzekunze haisati yasimudzirwa uye kushandiswa munyika; Zvimwe zvemhando yepamusoro-tekinoroji zvekurapa zvichiri kushama muChina. Tichitora denda reSARS rakabuda rikapararira muChina pakutanga kwegore semuenzaniso, mamwe matunhu muChina haana kukwanisa kuwana zviyero zvemidziyo yekudzivirira uye zvigadzirwa zvine mashandiro akanaka ekudzivirira pamberi pekuputika kwakangoerekana kwaitika. Parizvino, zvipfeko zvekuvhiya zvevazhinji vevashandi vekurapa muChina hazvina kugadzirirwa zvipfeko zveSM S zvine kudzivirirwa kwakanaka pabhakitiriya nemvura yemuviri uye zvakagadzika kupfeka nekuda kwenyaya dzemitengo, izvo zvisingafadzi zvakanyanya kuchengetedzwa kwevashandi vekurapa. Nekukurumidza kukura kwehupfumi hweChina uye kuwedzera kuziva kwehutsanana pakati pevanhu, munda uyu unozoitawo musika wakakura wemachira asina kurukwa.
Geosynthetic zvinhu
Geosynthetic zvinhu imhando yezvigadzirwa zveinjiniya zvakagadziridzwa kuChina kubva kuma1980 uye zvakakurumidza kuvandudzwa mukupera kwema1990, nehuwandu hwekushandiswa. Pakati pazvo, machira, machira asina-akarukwa, uye zvinhu zvawo zvakasanganiswa chikamu chikuru chemicheka yeindasitiri, inozivikanwawo se geotextiles. Geotextiles anonyanya kushandiswa mumapurojekiti akasiyana einjiniya ehurumende, akadai sekuchengetedza mvura, zvekufambisa, kuvaka, zviteshi zvezvikepe, nhandare dzendege, uye zvivakwa zvemauto, kuwedzera, kudhiza, kusefa, kuchengetedza, nekuvandudza huinjiniya uye hupenyu hwebasa. China yakatanga kushandisa geosynthetics pachiyedzo mukutanga kwema1980, uye pakazosvika 1991, huwandu hwekushandisa hwakange hwapfuura miriyoni mativi emamita kekutanga nekuda kwenjodzi yemafashama. Dambudziko remafashamo muna 1998 rakakwezva kutarisisa kwemadhipatimendi enyika neeinjiniya, izvo zvakatungamira mukubatanidzwa kweiyo geosynthetics mumayero uye nekugadzwa kwezvinoenderana dhizaini dhizaini uye mirau yekushandisa. Panguva ino, zvigadzirwa zveChina geosynthetic zvatanga kupinda muchikamu chekusimudzira. Sekureva kwemishumo, muna 2002, kushandiswa kwegeosynthetics muChina kwakapfuura mamirioni mazana maviri nemakumi mashanu emamita kekutanga, uye akasiyana egeosynthetics ari kuwedzera serialized.
Nekuvandudzwa kwegeotextiles, iyo isiri-yakarukwa machira magadzirirwo emidziyo yakakodzera kugadzira zvigadzirwa zvakadaro muChina yakawanawo budiriro nekukurumidza. Yakavepo zvishoma nezvishoma kubva kune yakajairwa mapfupi fiber tsono nzira yekubaya nehupamhi isingasviki 2.5 metres mukutanga application nhanho kuenda kupfupi fiber tsono punching nzira ine hupamhi hwemamita 4-6 uye iyo polyester spunbond yekubaya tsono nzira ine hupamhi hwe3.4-4.5 metres. Zvigadzirwa hazvisati zvangogadzirwa zvechinhu chimwe chete, asi kazhinji zvinoshandisa musanganiswa kana musanganiswa wezvakawanda zvinhu, izvo zvinovandudza zvakanyanya kunaka uye zvinosangana nekumira kwezvinodiwa zvezvigadzirwa. Nekudaro, kubva pamaonero ehuwandu hweinjiniya munyika yedu, geotextiles iri kure nekuzivikanwa zvakanyanya, uye chikamu chezvigadzirwa zvisiri-zvakarukwa zvakare chakaderera zvakanyanya kana zvichienzaniswa nenyika dzakabudirira. Inofungidzirwa kuti chikamu chemicheka isina-yakarukwa mu geotextiles muChina inongosvika makumi mana muzana, nepo muUnited States yatove kutenderedza 80%.
Kuvaka zvinhu zvisingapindi mvura
Kuvaka zvinhu zvisingapindi mvura zvakare iri kukurumidza kusimukira maindasitiri zvinhu muChina mumakore achangopfuura. Mumazuva ekutanga enyika yedu, akawanda edenga rekudzivirira mvura aive matayi epepa uye fiberglass tainzwa. Kubva pakuvandudzwa nekuvhurwa, mhando yeChina yezvivakwa zvekuvaka yawana budiriro isati yamboitika, uye kushandisa kwavo kwasvika makumi mana muzana ekushandiswa kwese. Pakati pazvo, kushandiswa kweasphalt yekudzivirira mvura membranes yakadai seSBS neAPP kwakawedzerawo kubva pamamiriyoni makumi maviri emamita 1998 asati asvika kusvika pamamiriyoni makumi manomwe emamita muna 2001. Nekusimudzirwa kwekuwedzera kwekuedza kuvaka kwezvivako, China ine musika mukuru unogona kuitika mumunda uyu. Ipfupi fiber tsono yakarovera polyester tire base, spunbond tsono yakabaya polyester tire base, uye spunbond polypropylene uye isina mvura resin inoumbwa zvinhu zvinoramba zvichitora imwe musika mugove. Ehe, kunze kwemhando yekudzivirira mvura, nyaya dzekuvaka dzakasvibirira, kusanganisira petroleum based materials, dzinodawo kutariswa mune ramangwana.
