I-China ihlukanisa izindwangu zezimboni zibe izigaba eziyishumi nesithupha, futhi okwamanje izindwangu ezingalukiwe zinengxenye ethile emikhakheni eminingi, njengezokwelapha, ezempilo, ukuvikelwa kwemvelo, i-geotechnical, ukwakhiwa, izimoto, ezolimo, izimboni, ukuphepha, isikhumba sokwenziwa, ukupakisha, ifenisha, amasosha, njalonjalo. Phakathi kwazo, izindwangu ezingalukiwe sezivele zinengxenye enkulu futhi sezisetshenziswa kabanzi emikhakheni efana nenhlanzeko, ukuhlunga imvelo, ukwakhiwa kwe-geotechnical, isikhumba sokwenziwa, ezezimoto, izimboni, ukupakisha kanye nefenisha. Kwezokwelapha, ezolimo, i-canopy, ezokuvikela, ezempi kanye neminye imikhakha, nabo sebefinyelele izinga elithile lokungena emakethe.
Izinto zokuhlanzeka
Izinto zokuhlanzeka ikakhulukazi zifaka amanabukeni namanabukeni ahlanzekile ukuze asetshenziswe nsuku zonke ngabesifazane nezinsana, imikhiqizo yokungakwazi ukuzithiba yabantu abadala, izinto zokunakekela izingane, izinto zokuhlanza zasendlini nezomphakathi, okokugeza okumanzi okuphekwa, njll. Amanabukeni ezindlu zangasese akhula ngokushesha futhi asetshenziswa kakhulu e-China. Kusukela ekuqaleni kwawo-1990, isivinini sabo sokuthuthukiswa besimangalisa. Ngo-2001, izinga labo lokungena ezimakethe lase lidlule ku-52%, ngokusebenzisa izingcezu eziyizigidi eziyizinkulungwane ezingu-33. Kulindeleke ukuthi ngo-2005, izinga labo lokungena emakethe lifinyelele ku-60%, ngokusetshenziswa kwezingcezu eziyizigidi eziyizinkulungwane ezingu-38.8. Ngokuthuthuka kwayo, indwangu yayo, ukwakheka kwayo, nezinto ezimuncayo ezakhelwe ngaphakathi kube nezinguquko ezishintshayo. Indwangu kanye nezingxenye ezimelene nezinhlangothi ezimelene ne-seapage ngokuvamile zisebenzisa umoya oshisayo, ukugoqa oshisayo, izindwangu ezinhle ze-denier spunbond nonwoven, kanye ne-SM S (i-spunbond/meltblown/spunbond) izinto ezihlanganisiwe. Izinto zangaphakathi zokumunca nazo zisebenzisa kabanzi ukugeleza komoya we-pulp okwenza izinto ezincanyana kakhulu eziqukethe ama-polymers e-SAP superabsorbent; Nakuba izinga lokungena emakethe lamanabukeni ezingane lisephansi, liphinde lazuza ukuthuthukiswa okuphawulekayo eminyakeni yamuva; Kodwa-ke, ukuduma kwemikhiqizo yabantu abadala abangakwazi ukuzithiba, izinto zokunakekela izingane, izinto zokuhlanza indlu nezindawo zomphakathi, njll. akuphakeme e-China, futhi abanye abakhiqizi bendwangu engalukiwe ye-spunlace bakhiqiza izinto zokusula ezenziwe nge-spunlace ikakhulukazi ukuze zithunyelwe ngaphandle. I-China inabantu abaningi futhi ukusabalala kwempahla yokuhlanzeka kusephansi. Ngokuthuthuka okuqhubekayo kwezinga lomnotho kazwelonke, lo mkhakha uzoba ngenye yezimakethe ezinkulu zezinto ezingalukiwe eChina.
Izimpahla zezokwelapha
Lokhu ikakhulukazi kubhekiselwa emikhiqizweni ehlukahlukene yendwangu kanye nengalukiwe esetshenziswa ezibhedlela, njengezigqoko zokuhlinzwa, amakepisi okuhlinza, imaski, izembozo zokuhlinzwa, izembozo zezicathulo, izingubo zesiguli, izimpahla zombhede, i-gauze, amabhandeshi, okokugqoka, amateyipu, izembozo zemishini yezokwelapha, izitho zokwenziwa zomuntu, njalo njalo. Kulo mkhakha, izindwangu ezingalukiwe zidlala indima ephumelela kakhulu ekuvikeleni amagciwane kanye nasekuvimbeleni ukutheleleka ngegciwane. Amazwe athuthukile anesabelo semakethe yendwangu engalukiwe engu-70% kuya ku-90% emikhiqizweni yendwangu yezokwelapha. Kodwa-ke, e-China, ngaphandle kwenani elincane lemikhiqizo efana nezingubo zokuhlinzwa, imaski, izembozo zezicathulo, namateyipu enziwe ngezindwangu ze-spunbond, ukusetshenziswa kwezinto ezingezona ezilukiweyo akukakasakazeki. Ngisho nemikhiqizo yokuhlinza engalukiwe eke yasetshenziswa inegebe elibonakalayo ekusebenzeni nasezingeni uma kuqhathaniswa namazwe asethuthukile. Isibonelo, izingubo zokuhlinza emazweni athuthukile njengaseYurophu naseMelika zivame ukusebenzisa ukunethezeka ukugqokwa futhi zibe nezindawo ezinhle zokuvikela amagciwane kanye negazi, njengezinto eziyinhlanganisela ye-SM S noma izinto ezingezona ezilukiwe ezinama-hydroentangled.
Kodwa-ke, e-China, izingubo zokuhlinza ze-spunbond nefilimu yepulasitiki zivame ukusetshenziswa kakhulu, futhi i-SM S ayikamukelwa kabanzi okwamanje; Amabhandeshi asetshenziswa kakhulu ane-hydroentangled non-woven, i-gauze, namadrapes okuhlinza ane-hydroentangled ahlanganiswe ne-wood pulp emazweni angaphandle akukakathuthukiswa futhi asetshenziswe ekhaya; Ezinye izinto zokwelapha zobuchwepheshe obuphezulu azinalutho e-China. Sithatha ubhubhane lwe-SARS olwavela futhi lwasakazeka eChina ekuqaleni konyaka njengesibonelo, ezinye izifunda eChina azikwazanga ukuthola izindinganiso ezifanele zemishini yokuzivikela kanye nezinto zokwakha ezisebenza kahle zokuvikela lapho kuqubuka udlame kungazelelwe. Njengamanje, izingubo zokuhlinza zeningi labasebenzi bezokwelapha e-China azihlome ngezimpahla ze-SM S ezinomphumela omuhle wokuvikela kubhaktheriya noketshezi lomzimba futhi ezigqoka kahle ngenxa yezinkinga zamanani, okuyinto engathandeki kakhulu ekuvikelweni kwabasebenzi bezokwelapha. Ngokukhula okusheshayo komnotho waseShayina kanye nokuqwashisa okwandayo kwenhlanzeko phakathi kwabantu, lo mkhakha uzophinde ube imakethe enkulu yezindwangu ezingalukiwe.
Izinto ze-Geosynthetic
Izinto zokwakha ze-Geosynthetic ziwuhlobo lwempahla yobunjiniyela eye yathuthukiswa eShayina kusukela ngeminyaka yawo-1980 futhi yathuthukiswa ngokushesha ngasekupheleni kwawo-1990, ngenani elikhulu lokusetshenziswa. Phakathi kwazo, izindwangu, izindwangu ezingezona ezilukiwe, nezinto zazo ezihlanganisiwe ziyisigaba esikhulu sezindwangu zezimboni, ezaziwa nangokuthi i-geotextiles. Ama-geotextiles asetshenziswa kakhulu kumaphrojekthi wobunjiniyela bomphakathi ahlukahlukene, njengokugcina amanzi, ezokuthutha, ukwakhiwa, amachweba, izikhumulo zezindiza, nezindawo zamasosha, ukuthuthukisa, ukudonsa amanzi, ukuhlunga, ukuvikela kanye nokwenza ngcono izinga lobunjiniyela nempilo yesevisi. I-China yaqala ukusebenzisa i-geosynthetics ngesisekelo sokuhlola ekuqaleni kwawo-1980, futhi ngo-1991, umthamo wokufaka isicelo wawusudlule i-100 million square metres okokuqala ngqa ngenxa yezinhlekelele zezikhukhula. Isikhukhula esiyinhlekelele ngo-1998 sadonsa ukunaka kweminyango kazwelonke neyezobunjiniyela bomphakathi, okwaholela ekufakweni ngokusemthethweni kwe-geosynthetics kumazinga kanye nokusungulwa kwemininingwane yedizayini ehambisanayo kanye nemithethonqubo yokusetshenziswa. Kuleli qophelo, izinto ze-geosynthetic zaseChina seziqalile ukungena esigabeni sokuthuthuka okujwayelekile. Ngokwemibiko, ngo-2002, ukusetshenziswa kwe-geosynthetics e-China kweqa ama-square metres ayizigidi ezingama-250, futhi izinhlobonhlobo ze-geosynthetics ziya ngokuya zihlukaniswa.
Ngokuthuthukiswa kwama-geotextiles, imishini yenqubo yendwangu engalukiwe efaneleka ukukhiqiza imikhiqizo enjalo eChina nayo izuze intuthuko ngokushesha. Kancane kancane iye yavela endleleni evamile yokubhoboza inaliti ye-fiber emfushane enobubanzi obungaphansi kwamamitha angu-2.5 ekuqaleni kwesigaba sokufaka isicelo yaya endleleni yokubhoboza inaliti ye-fiber emfushane enobubanzi obungamamitha angu-4-6 kanye nendlela yokubhoboza inaliti ye-polyester spunbond enobubanzi obungamamitha angu-3.4-4.5. Imikhiqizo ayisanziwe nje ngento eyodwa, kodwa ngokuvamile isebenzisa inhlanganisela noma inhlanganisela yezinto eziningi, ethuthukisa kakhulu ikhwalithi futhi ihlangabezane nezidingo zokumiswa kwemikhiqizo. Kodwa-ke, ngokombono wenani lobunjiniyela ezweni lakithi, ama-geotextile asekude ukuthi adume kabanzi, futhi ingxenye yemikhiqizo engalukiwe nayo iphansi kakhulu uma iqhathaniswa namazwe athuthukile. Kulinganiselwa ukuthi ingxenye yezindwangu ezingezona ezilukiwe kuma-geotextiles e-China icishe ibe ngama-40%, kanti e-United States isivele icishe ibe ngu-80%.
Izinto zokwakha ezingangeni manzi
Izinto zokwakha ezingangeni manzi nazo ziyizimboni ezikhula ngokushesha eShayina eminyakeni yamuva nje. Ezinsukwini zokuqala zezwe lakithi, izinto eziningi zokuvikela amanzi ophahleni kwakuyithayi lephepha kanye nethayi le-fiberglass. Selokhu kwaba nezinguquko nokuvulwa, uhlobo lwempahla yokwakha yaseShayina luzuze intuthuko engakaze ibonwe, futhi ukusetshenziswa kwazo sekufinyelele ku-40% wengqikithi yokusetshenziswa. Phakathi kwazo, ukusetshenziswa kolwelwesi oluguquliwe lwe-asphalt lokuvikela amanzi njenge-SBS kanye ne-APP kuphinde kwanda kusuka ngaphezu kwamamitha-skwele ayizigidi ezingu-20 ngaphambi kuka-1998 kuya ku-70 million square metres ngo-2001. Ngokugqugquzelwa kokwandisa imizamo yokwakha ingqalasizinda, i-China inemakethe enkulu engaba khona kulo mkhakha. Inalithi yefiber emfushane ebhoboze isisekelo sethayi le-polyester, inaliti ye-spunbond ebhoboze isisekelo sesondo le-polyester, kanye ne-spunbond polypropylene nezinto ezihlanganisiwe zeresin engangeni manzi kuzoqhubeka nokuba nesabelo semakethe esithile. Yiqiniso, ngaphezu kwekhwalithi yokuvimbela amanzi, izinkinga zokwakha eziluhlaza, kuhlanganise nezinto ezisekelwe ku-petroleum, nazo zidinga ukucatshangelwa esikhathini esizayo.
