Konke HDPE: ukuthi kuyini, izakhiwo kanye nezicelo

Geomembranes zesimanje roll polymeric izinto, okuyinto ziyahlukahluka ukushuba of 1 kuya 4 mm. Yakhiwa polyethylene, polypropylene, polyvinyl chloride nezinye izinto nge ukushuba ubuncane 0.5 mm. Ngokuphathelene ububanzi bayo, abese kungaba afika kwangu-7 m, kanye eziyisisekelo yokusebenza isici ukuthi geomembrane waterproof ngokuphelele. It wenabisa ububanzi bokusebenzisa salo, esiwulwazi, phakathi kokunye, kuzoxoxwa ngezansi.

izakhiwo

Namhlanje i-evame kakhulu geomembrane HDPE, ukuthi kuyini, kuyothiwa echazwe esihlokweni. geomembrane Modern ngesisekelo polyethylene ungaba surface ngomala noma bushelelezi. Lokhu kuzovumela ukusizakala lokuzikhethela ukusebenza uhlobo oluthile lomsebenzi. Phakathi izici eziyinhloko yalesi material kungenziwa isehlane okusezingeni eliphezulu izimfanelo ungangenisi amanzi. izinto ezifana nalezi izakhiwo okusezingeni eliphezulu ngokomzimba futhi mechanical, okubenza babe ukwahlukahlukana. Lapho kukhona nabo uketshezi, inqubo okusheshayo singenzeka kuphela ezingeni yamangqamuzana ezinto eziphilayo. By endleleni kungaba kuqashelwe ukuthi kwangathi impahla isetshenziselwe ukuxhumana ngqo ngamanzi. Geomembranes amelana amakhemikhali, zingabantu ukuzinza ntathu, zivumelanise nezimo futhi ube ngeke inqamuke futhi ibhekane zonke izinhlobo elikhulu, ngaphandle kokulimaza kwalo. Material elongates ngaphansi kwethonya umthwalo ukuba 850%, futhi amandla awo eqine kungenzeka elilingana 26,2 MPA.

egqoke izimfanelo

Uma unesithakazelo geomembrane HDPE, ukuthi kuyini, wena ngokuphelele kumele bazi. Lokhu kwaziswa olumelana emisebeni yelanga, lokushisa umehluko, futhi lungasetshenziswa zokuzamazama zokuzamazama komhlaba. Kuyinto ukumelana lubhoboze futhi ingasetshenziswa for ezahlukene kwezicelo. Sebenzisa geomembrane kungaba kuzo zonke izindawo zezulu. Uma ulandela imithetho ukufakwa professional, ukuphila yokusebenza ye geomembrane lingafika ku engu 90.

Ububanzi bokusebenzisa

Eminyakeni yamuva, kuba ngaphezulu esetshenziswa kabanzi geomembrane HDPE. Kuyini, ngaphambi kokuthenga kumelwe uwucele. Lokhu kwaziswa sinezici yemvelo neyamakhemikhali esihle, lokhu kunikeza kungenzeka ngokusebenzisa ukuvuselelwa izikrini uyavikeleka lokuqoqa imfucuza liquid okuqinile akunakubangelwa lapha ezinobuthi. Geomembrane advantageously esetshenziswa ukuvuselelwa emadanyini, landfills, umquba kanye nokuvikela enamathela metal anticorrosive, ukhonkolo kanye nezinye izakhiwo, baphinde baxhumane amanzi ahlanzekile ngesikhathi operation. On ukudayiswa ungathola izinhlobo eziningana geomembrane HDPE: Solmax 840, 860 kanye 880. Ngayinye yalezi izinto - izici zabo izinkomba ezithile. Ngokwesibonelo, ubuncane ukujiya isilinganiso Icala lokuqala 1 mm, kanti eyesibili neyesithathu - 1.5 2 mm, ngokulandelana. ubukhulu roll kuyinto 6,8x238; 6,8x159; 6,8x122 mm, ngokulandelana, ngayinye yalezi izinhlobo.

inhlanganiso

I kwabantu impahla kuzo zonke izimo ezintathu kuyafana, futhi ungase uqale kusuka 0,926 g / cm². Ngokuqondene kwabantu ulwelwesi, kungase elilingana 0,939 g / cm², lesi silinganiso ngezinye izikhathi ezingaphezu. Okuqukethwe carbon ezimnyama kuso zingaba phakathi 2 kuya ku-3%. Voltage-impahla nge ukunwebeka kungenzeka elilingana 14.7; 22 noma 29% ngokulandelana.

izakhiwo ezengeziwe

abakhi abangochwepheshe nekhaya izingcweti zisebenzisa HDPE geomembrane, - kuyini, kufanele ucele ngaphambi yezitolo. Lokhu kwaziswa kunezinzuzo eziningi, phakathi kwawo - yizinhlobonhlobo, ukusebenza kahle, okusezingeni eliphezulu obandayo workability, ukusebenza kahle kanye nobungane kwemvelo. Functional izinga geomembrane ukunikeza izimfuno ukwakhiwa kwezakhiwo ukuze nokugcinwa kukadoti ingozi ka-class ehlukene. geomembrane okunjalo esetshenziswa landscape nobunjiniyela wokubacindezela ngempumelelo. Material kuyinto ukonga, ukusetshenziswa kwalo kunciphisa tindleko operation nokwakhiwa. Kungakhathaliseki ukuthi indawo ukusetshenziswa, ukusetshenziswa geomembranes kunciphisa bomsebenzi, nenani izinto, futhi ikuvumela ukuba ugcwalise iphrojekthi ngokushesha ngangokunokwenzeka. HDPE geomembrane loke nje lidume ngokuthunga okusezingeni eliphezulu kubekwa processability. Siqukethe ngalolo ububanzi 7 amamitha kuyehla isidingo ezivuzayo ukuthi ukusebenzisa imishini Welding. Ngakho, abaculi akudingeki isidingo ukwenza ezivuzayo bhukwana emalungeni panel.

Geomembranes okuhlala kakhulu futhi athembekile msebenzi. Amasu yathuthukiswa, futhi izinga isesikhathini par. Phakathi kwezinye izinto, okokusebenza ngokuphelele imvelo. It is lisetshenziswe ukuvuselelwa yokuvikela izindawo zemvelo. Ngokusekelwe Ukucaciswa, kungenzeka ukuqinisekisa okuthembekile ngabodwa izakhiwo, okuyinto akufaki nokuhanjiswa kwe- imithombo ukungcola.

Izici isicelo: esigabeni wokulungiselela

HDPE (polyethylene) ulaliswe esisekelweni lelungiselelwe, elalikade kususwa amatshe, udoti, engokwemvelo kanye nezinye izinto bazokwazi kulimaze lendwangu. Kwenzeka ukuze ebusweni akusho ukuhlangabezana nezidingo ngenhla, kulezi zimo kunconywa ukusebenzisa ungqimba ecashile zokuzivikela, esakhiwa yendwangu needled. Kubalulekile ukuba sithathe izinyathelo ukunivalela ematfuba izindawo wayenemfuyo unamanzi ebusweni eyisisekelo ungqimba.

impahla Ukubeka

Ngesikhathi inhliziyo geotextile - HDPE. HDPE ulaliswe ngokuvumelana nezimiso ezithile, okwakuyoholela akuphikisani ubunjalo le nto. Kumele siqale ukusebenza ngemva ukulungiswa uhlelo ukufakwa. Kulesi ngokuningiliziwe kubonisa usayizi isihlobo isikhundla imidwebo, kanye welds. umsebenzi Ukufakwa kuzomele sifake ukugcinwa izinto ezithile, phakathi kwawo - isiqondiso ukulandelana ukufakwa, wokugubha panel nezihlanganiso ashiselwe, indawo izakhiwo lohlobo ukukhiqizwa amapayipi kanye uxhumano lezo zakhiwo. I amashidi kufanele kahle ukuze ezivuzayo awazange sawela ngesinye isikhathi. I Isikhala esincane phakathi amaphuzu empambana kumele kube 0.5 m HDPE (okusezingeni eliphezulu ukuminyana polyethylene - ngesisekelo impahla). Kufanele kuyendlulela ngumuntu ububanzi ku uhla kusuka 100 kuya ku-150 mm. Ukunamathela lo mthetho kumele libe kule transverse kanye izinkomba longitudinal. Master kumele aqinisekise inombolo okungenani welds eyenziwe inqubo extrusion.

Emithambekeni ye impahla kumele embondelene kusukela phezulu kuya phansi, ngakho-ke kuyadingeka ukuba sebenzisa idivaysi ekhethekile okuthiwa unqamula. kufanele ahlinzeke khona ihange zokuthola imisele geomembrane phezu emthambekeni brow. Uma kukhona isidingo sokuqinisa geomembrane kwamanzi ukhonkolo, kubalulekile ukulungiselela izakhi ezikhethekile yasibamba, kungase amapuleti ingcindezi futhi dowels, geomembrane emapheshana. kusengaphambili kwakamuva okumelwe lihambisane nendlela kobuso amahange ukhonkolo. Njengoba iziqobosho angasebenza futhi ifaka.

Izincomo Welding

Yini obungayenza wena geomembrane kuzosetshenziswa alalelwayo - HDPE 1,5 mm noma yimuphi omunye ukujiya, Welding ezivuzayo kumele kwenziwe nge imishini ekhethekile, oveza agcwalise isisu ngomoya wasempumalanga. I samuntu okunye ongenza uqhekeko ashisayo, noma indlela kuhlanganiswe. Inketho zokugcina ikuvumela ukwenza-umphetho ezimbili, okuzodingeka isiteshi ukuhlolwa. Ngemva kwalokho ukuze bakwazi ukulawula izinga joint weld. Uma kudingeka usebenze izindawo wayiswa noma izindawo ngezidingo, kungcono ukusebenzisa ubuchwepheshe extrusion Welding.

esikhundleni isiphetho

HDPE kwabantu okuyinto okukhulunywe ngaye ngenhla, kungenzeka nesithakazelo hhayi kuphela ochwepheshe kodwa futhi ebona indlu amakhosi, abahlela okusebenzisa lokho kwaziswa ukuze umsebenzi. Phakathi kwezinye izinto, ungase ube nentshisekelo kwezinye izakhiwo esiyingqayizivele ngaphezulu geomembranes. Phakathi kwazo ukuhlinzeka kakhudlwana futhi inertness ukuba alkalis kanye acid, okuyinto abe pH ku uhla 1.5 kuya 14. Ekusebenteni, umthelela ezishisayo yokuguga ingekho, kodwa yesiqinisekiso ejwayelekile on impahla self-ukufakwa engu-75.
