I-China yahlula amalaphu emizi-mveliso ngokweendidi ezilishumi elinesithandathu, kwaye ngoku amalaphu angalukwanga athatha isabelo esithile kwiindidi ezininzi, ezinje ngezonyango, ezempilo, ukukhuselwa kokusingqongileyo, i-geotechnical, ulwakhiwo, iimoto, ezolimo, umzi-mveliso, ukhuseleko, ufele lokwenziwa, ukupakishwa, ifenitshala, umkhosi, njalo njalo. Phakathi kwazo, amalaphu angalukwanga sele ethathe inxaxheba enkulu kwaye asetyenziswa ngokubanzi kumasimi anje ngococeko, ukuhluzwa kwendalo, ulwakhiwo lwe-geotechnical, ufele olwenziweyo, iimoto, umzi-mveliso, ukupakishwa kunye nefanitshala. Kwezonyango, ezolimo, i-canopy, ukukhusela, umkhosi kunye nezinye iindawo, baye bafikelela kwinqanaba elithile lokungena kwimarike.
Izinto zococeko
Izinto zococeko zibandakanya i-diapers kunye ne-sanitary napkins yokusetyenziswa kwansuku zonke ngabasetyhini kunye neentsana, iimveliso zokungaziphathi kakuhle kwabantu abadala, ii-wipes zokunakekelwa kwabantwana, ii-wipes zokucoca indlu kunye noluntu, i-wet wipes for catering, njl. Ukususela ekuqaleni kwee-1990, isantya sabo sophuhliso siye saphawuleka. Ngo-2001, izinga labo lokungena kwimarike liye ladlula i-52%, ngokusetyenziswa kweebhiliyoni ezingama-33. Kulindeleke ukuba ngo-2005, izinga labo lokungena kwimarike liya kufikelela kwi-60%, kunye nokusetyenziswa kweebhiliyoni ze-38.8. Ngophuhliso lwayo, ilaphu layo, ulwakhiwo, kunye nezinto ezifunxayo ezakhelwe ngaphakathi ziye zatshintsha. Ilaphu kunye neendawo ezisecaleni ezichasene nekhasi ziqhele ukusebenzisa umoya oshushu, ukuqengqeleka okushushu, amalaphu amahle e-denier spunbond angalukwanga, kunye ne-SM S (spunbond/meltblown/spunbond) imathiriyeli edibeneyo. Izinto zangaphakathi zokufunxa zikwasebenzisa ngokubanzi ukuhamba komoya we-pulp zenza izinto ezinqabileyo ezinqabileyo ezine-SAP superabsorbent polymers; Nangona izinga lokungena kwimarike ye-diapers yomntwana lincinci, liye lafumana uphuhliso olubalulekileyo kwiminyaka yamuva nje; Nangona kunjalo, ukuduma kweemveliso zabantu abadala zokungazixhasi, ukosula iintsana, ukosula kwasekhaya kunye neendawo zikawonke-wonke zokucoca, njl. njl. akukho phezulu e-China, kwaye abanye abavelisi belaphu le-spunlace abangalukwanga bavelisa izosuli ze-spunlace ikakhulu ezithunyelwa kumazwe angaphandle. I-China inabemi abaninzi kwaye ukuxhaphaka kwezinto zococeko kusephantsi. Ngophuculo olongezelelweyo lwenqanaba loqoqosho lwesizwe, le ntsimi iya kuba yenye yeemarike ezinkulu zezinto ezingalukwanga eTshayina.
Izixhobo zonyango
Oku ikakhulu kubhekiselele kwiimveliso ezahlukeneyo zamalaphu kunye nezingalukwanga ezisetyenziswa ezibhedlele, ezinje ngeegawuni zotyando, iminqwazi yotyando, iimaski, izigqubuthelo zotyando, izigqubuthelo zezihlangu, iigawuni zesigulana, iimpahla zokulala, i-gauze, amabhandeji, ukunxiba, iiteyiphu, izixhobo zonyango ezigqumayo, amalungu angengowamntu, njalo njalo. Kule ntsimi, amalaphu angalukwanga adlala indima esebenzayo ekukhuseleni iibhaktheriya kunye nokuthintela usulelo olunqamlezayo. Amazwe aphuhlileyo anesabelo semarike yelaphu elingalukwanga elingama-70% ukuya kuma-90% kwiimveliso zamalaphu zonyango. Nangona kunjalo, e-China, ngaphandle kwenani elincinci leemveliso ezinje ngeegawuni zotyando, iimaski, izigqubuthelo zezihlangu, kunye neeteyiphu ezenziwe ngamalaphu e-spunbond, ukusetyenziswa kwempahla yelaphu elingalukwanga akukaxhaphakanga. Nkqu neemveliso zotyando ezingalukwanga eziye zasetyenziswa zinomsantsa obonakalayo ekusebenzeni nakwibakala xa kuthelekiswa namazwe aphuhlileyo. Umzekelo, iigawuni zotyando kumazwe aphuhlileyo anje ngeYurophu neMelika zihlala zisebenzisa ngokukhululekileyo ukunxiba kwaye zineempawu ezilungileyo zebhaktheriya kunye nokukhusela igazi, njengezinto ezihlanganisiweyo ze-SM S okanye imathiriyeli engalukwanga nge-hydroentangled.
Nangona kunjalo, e-China, ilaphu le-spunbond kunye ne-plastiki ifilimu ehlanganisiweyo iingubo zotyando zisetyenziswa ngokuqhelekileyo, kwaye i-SM S ayikamkelwa ngokubanzi okwangoku; Iibhandeji ezisetyenziswa ngokubanzi ezine-hydroentangled non-woven, i-gauze, kunye ne-hydroentangled drapes yotyando exutywe nentlaka yeplanga kumazwe angaphandle ayikakhuthazwa kwaye isetyenziswe ekhaya; Ezinye izixhobo zonyango ezikumgangatho ophezulu azinanto eTshayina. Ukuthatha ubhubhani we-SARS owavela kwaye wasasazeka e-China ekuqaleni konyaka njengomzekelo, eminye imimandla yase-China ayikwazanga ukufumana imigangatho yezixhobo zokhuseleko ezifanelekileyo kunye nezixhobo ezisebenza kakuhle zokukhusela ebusweni bokuqhambuka ngequbuliso. Okwangoku, iimpahla zotyando zabasebenzi abaninzi bezonyango e-China azixhotyiswanga ngempahla ye-SM S enefuthe elikhuselayo kwiibhaktheriya kunye nolwelo lomzimba kwaye ikhululekile ukunxiba ngenxa yemicimbi yamaxabiso, engafanelekanga kakhulu kukhuseleko lwabasebenzi bezonyango. Ngokukhula okukhawulezayo koqoqosho lwaseTshayina kunye nokwanda kolwazi lococeko phakathi kwabantu, le ndawo iya kuba yintengiso enkulu yamalaphu angalukwanga.
Izinto zeGeosynthetic
Iimathiriyeli zeGeosynthetic luhlobo lwemathiriyeli yobunjineli eye yaphuhliswa e-China ukusukela ngeminyaka yoo-1980 kwaye yaphuhliswa ngokukhawuleza ngasekupheleni kweminyaka yee-1990, kunye nesixa esikhulu sokusetyenziswa. Phakathi kwazo, amalaphu, amalaphu angalukwanga, kunye nezixhobo zawo ezidityanisiweyo ludidi oluphambili lwelaphu lemizi-mveliso, elaziwa ngokuba yi-geotextiles. Ii-geotextiles zisetyenziswa ikakhulu kwiiprojekthi zobunjineli boluntu, ezinje ngogcino lwamanzi, uthutho, ulwakhiwo, amazibuko, izikhululo zeenqwelo moya, kunye nezixhobo zomkhosi, ukomeleza, ukukhupha amanzi, ukuhluza, ukukhusela nokuphucula umgangatho wobunjineli kunye nobomi benkonzo. I-China yaqala ukusebenzisa i-geosynthetics kwisiseko solingo ekuqaleni kweminyaka yoo-1980, kwaye ngo-1991, umthamo wesicelo wawugqithise kwi-100 yezigidi zeemitha zemitha okokuqala ngenxa yeentlekele zempuphuma. Izandyondyo zemvula zika-1998 zatsala umdla kwisebe lesizwe nelobunjineli boluntu, nto leyo ekhokelele ekudityanisweni ngokusesikweni kwe-geosynthetics kwimigangatho kunye nokusekwa kwengcaciso yoyilo oluhambelanayo kunye nemigaqo yokusetyenziswa. Ngeli xesha, izinto ze-geosynthetic zaseChina ziye zaqala ukungena kwinqanaba lophuhliso olusemgangathweni. Ngokweengxelo, ngo-2002, ukusetyenziswa kwe-geosynthetics e-China kwadlula i-250 yezigidi zeemitha zesikwere okokuqala, kwaye iindidi ze-geosynthetics ziya zisanda ngokulandelelana.
Ngophuhliso lwe-geotextiles, izixhobo zenkqubo yelaphu elingalukwanga zilungele ukuvelisa iimveliso ezinjalo e-China nazo ziphumelele uphuhliso olukhawulezayo. Iye yavela ngokuthe ngcembe ukusuka kwindlela eqhelekileyo yokugqobhoza kwenaliti yefiber emfutshane enobubanzi obungaphantsi kwe-2.5 yeemitha kwisigaba sokuqala sokufakwa kwesicelo ukuya kwindlela yokugqobhoza yenaliti emfutshane yobubanzi obuziimitha ezi-4-6 kunye ne-polyester spunbond yokuhlatywa kwenaliti ngobubanzi obuziimitha ezi-3.4-4.5. Iimveliso azisenziwanga nje ngento enye, kodwa zihlala zisebenzisa indibaniselwano okanye indibaniselwano yezinto ezininzi, eziphucula kakhulu umgangatho kwaye zihlangabezane neemfuno zomgangatho weemveliso. Nangona kunjalo, ngokwembono yobuninzi bobunjineli kwilizwe lethu, i-geotextiles ikude ukuba yaziwe ngokubanzi, kwaye umyinge weemveliso ezingalukwanga nazo usezantsi kakhulu xa kuthelekiswa namazwe aphuhlileyo. Kuqikelelwa ukuba umlinganiselo wamalaphu angalukwanga kwi-geotextiles e-China kuphela malunga ne-40%, ngelixa e-United States sele sele ijikeleze i-80%.
Ukwakha izinto zokungena manzi
Izinto zokwakha ezingangeni manzi zikwayinto ekhula ngokukhawuleza kwimizi-mveliso eTshayina kwiminyaka yakutshanje. Ngeentsuku zokuqala zelizwe lethu, uninzi lwezixhobo zokukhusela amanzi eluphahleni yayingamatayara ephepha kunye nevili le-fiberglass. Ukususela ekuhlaziyweni kunye nokuvulwa, uhlobo lweChina lwezixhobo zokwakha luphumelele uphuhliso olungazange lubonwe ngaphambili, kwaye isicelo sabo sifikelele kwi-40% yokusetyenziswa okupheleleyo. Phakathi kwazo, ukusetyenziswa kweembrane ze-asphalt zokuthintela amanzi ezitshintshiweyo ezifana ne-SBS kunye ne-APP kuye kwanda ukusuka kwi-square yemitha ye-20 yezigidi ngaphambi ko-1998 ukuya kwi-70 yezigidi zeemitha ze-square ngo-2001. Inaliti yefiber emfutshane ehlatywe isiseko sevili lepolyester, inaliti yespunbond ehlatywe isiseko sevili lepolyester, kunye ne-spunbond polypropylene kunye nemathiriyeli ehlanganisiweyo yeresin engangeni manzi iya kuqhubeka ithatha isabelo esithile semarike. Ngokuqinisekileyo, ngaphezu komgangatho wokukhusela amanzi, imiba yezakhiwo eziluhlaza, kuquka izinto ezisekelwe kwi-petroleum, nazo kufuneka ziqwalaselwe kwixesha elizayo.
