HDPE geomembraneIkwabizwa ngokuba yi-polyethylene yoxinaniso oluphezulu olungangenwa yigeomembrane.Luhlobo lwemathiriyeli engangeni manzi, imathiriyeli ekrwada yipolymer ephezulu yeemolekyuli.Amacandelo aphambili yi-97.5% ye-HDPE kunye ne-2.5% ye-Carbon emnyama / i-anti-aging agent / anti-oxygen / UV i-absorbent / stabilizer kunye nezinye izixhobo.
Iveliswa ngobuchule obuphindwe kathathu be-extrusion ngesona sixhobo siphezulu esizenzekelayo esithengwe sisuka e-Itali.
I-Yingfan geomembranes zonke zidibana okanye zidlule i-US GRI kunye nemigangatho ye-ASTM.Umsebenzi wayo ophambili uchasene nokubona kunye nokuhlukaniswa., ngoko ke ukufakwa kweHDPE geomembrane lineribaluleke kakhulu.
Inkqubo yokufakela i-HDPE geomembrane idlala indima ebalulekileyo kwiiprojekthi ezingenamanzi kunye ne-anti-seepage.Thina, iShanghai Yingfan Engineering Material Co., LTD, sineqela lethu lofakelo lobuchwephesha ukubonelela ngeenkonzo zofakelo kwi-onsite, ngamava angaphezulu kweminyaka elishumi.Ke ndiyathemba ukuba esi sikhokelo sinokukunceda ngenene.
Esi sikhokelo sazisa indlela yofakelo ye-HDPE geomembrane.Ngesi sikhokelo, uya kuyazi ngcono indlela yokufaka i-HDPE geomembrane kwaye ikuncede ugcine ixesha kunye nomsebenzi.
Ngokubanzi, inkqubo yokufaka i-HDPE geomembrane ngolu hlobo lulandelayo:

4. Ukubeka i-geomembrane ye-HDPE
4.1 Vula i-geomembrane ye-HDPE kwindawo ethe tyaba kwaye usike izinto kwiprofayili yesidingo.
4.2 Umonakalo owenziwe ngumntu kufuneka ugwenywe ngexesha lenkqubo yokubeka.I-geomembrane kufuneka ibekwe ngokukhawuleza kwaye inciphise i-drape.Khetha ulwalathiso lokubeka olufanelekileyo ukunciphisa amandla adibeneyo.
4.3 Ukuguqulwa kwe-HDPE geomembrane kufuneka kunyanzeliswe malunga ne-1% -4%.
4.4 Yonke i-geomembrane ye-HDPE ephononongwayo kufuneka icinezelwe ngeengxowa zesanti okanye ezinye izinto ezinzima ukuthintela ukuvuthuza komoya kwe-geomembrane.
4.5 Ulwakhiwo lwangaphandle lwe-HDPE geomembrane kufuneka lube ngaphezulu kwe-5 °C, kwaye akukho mvula okanye imozulu engenakhephu ngaphantsi kwemimoya emi-4.Xa ubeka i-geomembrane, i-weld seam kufuneka incitshiswe.Ngaphantsi kwesiseko sokuqinisekisa umgangatho, izinto eziluhlaza kufuneka zigcinwe kangangoko kunokwenzeka, kwaye umgangatho unokuqinisekiswa lula.
4.6 Ukulinganisa: ukulinganisa ubungakanani bokusika;
4.7 Ukusika: Ukusika ngokweemfuno zobukhulu bokwenyani;ububanzi bomlenze yi-10cm ~ 15cm.
5. Welding HDPE geomembrane
5.1 Imo yemozulu:
(1) Iqondo lobushushu:4-40℃
(2) Imeko yokomisa, akukho mvula okanye amanye amanzi
(3) Isantya somoya ≤4 iklasi / h
5.2 ukuwelda okushushu:
5.2.1 I-geomembrane ezimbini ze-HDPE kufuneka zigqitywe ubuncinane ubuncinane be-15cm. I-membrane kufuneka ilungiswe kwaye iyancipha i-drape.
5.2.2 Indawo yokuwelda kufuneka icocwe kwaye iqinisekise ukuba akukho manzi, luthuli okanye ezinye iindawo.
5.2.3 Uvavanyo lwe-welding: Uvavanyo lwe-welding kufuneka lwenziwe ngaphambi kokuba kuqhutywe umsebenzi we-welding.I-welding yovavanyo iya kuqhutywa kwisampulu yezinto ezingabonakaliyo ezibonelelweyo.Ubude besampuli abuyi kuba ngaphantsi kwe-1 m kwaye ububanzi abuyi kuba ngaphantsi kwe-0.2 m.Emva kokuba uvavanyo lwelding lugqityiwe, iziqwenga ezintathu zovavanyo olubanzi oluyi-2.5 cm zasikwa ukuvavanya amandla okukrazula kunye namandla okucheba i-weld.
5.2.4 Ukuwelda: I-geomembrane idityaniswe kusetyenziswa umatshini wokuwelda kaloliwe ozenzekelayo.I-extrusion hot-melt welder iya kusetyenziswa apho umatshini wokuwelda kaloliwe ophindwe kabini awukwazi ukusebenza.Ihambelana nentonga ye-welding yezinto ezifanayo kunye ne-geomembrane.Inkqubo ye-welding yile ilandelayo: ukulungelelanisa uxinzelelo, ukubeka ubushushu, ukumisa isantya, ukuhlolwa kwamalungu, ukulayishwa kwe-geomembrane kumatshini, qalisa i-motor.Akuyi kubakho ioli okanye ioli okanye i-oyile. uthuli kwiindawo ezidibeneyo, kwaye akuyi kubakho nkunkuma, ukuxinana, ukufuma kunye nolunye udoti kwi-lap joint surface ye-geomembrane.Kufuneka icocwe phambi kokuba iwelding.
5.3 Extrusion welding;
(1)I-geomembrane ezimbini ze-HDPE kufuneka zigqithe ubuncinane nge-7.5cm.Indawo yokuwelda kufuneka icocwe kwaye iqinisekise ukuba akukho manzi, luthuli okanye ezinye iindawo.
(2)I-welding eshushu ayinakonakalisa i-geomembrane ye-HDPE.
(3)Intonga yokuwelda kufuneka icoceke kwaye yome.
Ukuwelda okushushu
Extrusion welding
Ngexesha lenkqubo ye-welding, ukuthintela i-HDPE geomembrane windblown, siya kubeka kwaye sidibanise ngexesha elifanayo.Ngaphambi kwe-welding, coca indawo yokudibanisa. isantya iyunifomu.Hlola umthungo welding emva Ukuphola ngokupheleleyo.
6. Ukuhlolwa komgangatho
6.1 Zitshekishe: Jonga kwaye urekhode yonke imihla.
6.2 Qwalasela yonke i-welding seam, ichaphaza le-welding kunye nendawo yokulungisa.
6.3 Emva kofakelo, ezinye izinto ezincinci ze-bump ziyavunyelwa.
6.4 Yonke i-welding seam eshushu kufuneka iphumelele uvavanyo olutshabalalisayo, uvavanyo lufana ne-adopt tensile machine ukusika kunye ne-peel, izinto ezisisiseko zitshatyalalisiwe ngelixa i-welding seam ingavunyelwanga ukuba ibhujiswe.
I-6.5 Ukubona uxinzelelo lomoya: Xa usebenzisa umatshini we-welding welding ye-automatic crawl, i-air cavity igcinwe phakathi kwe-weld, kwaye izixhobo zokuvavanya uxinzelelo lomoya kufuneka zisetyenziswe ukufumanisa amandla kunye nokuqina komoya.Emva kokuba ukwakhiwa kwe-weld kugqityiwe, zombini iziphelo ze-weld cavity zitywinwe, kwaye igumbi lomoya le-weld linyanzeliswa ukuya kwi-250 kPa kunye nesixhobo sokubona uxinzelelo lwegesi kwimizuzu emi-3-5, uxinzelelo lomoya akufanele lube ngaphantsi. 240 kPa Kwaye ke kwelinye isiphelo seweld, xa ukuvuleka kucinyiwe, isalathisi sebarometer sinokubuyiselwa ngokukhawuleza kwicala elinguziro njengoko kufanelekile.
7. Lungisa i-geomembrane ye-HDPE
Ngexesha lenkqubo yokubeka, naziphi na iziphene okanye i-geomembrane etshatyalalisiwe kufuneka ilungiswe ukunqanda impembelelo ekusebenzeni okungangeni manzi.
7.1 Umngxuma omncinci unokulungiswa nge-welding ye-extrusion, ukuba umngxuma mkhulu kune-6mm, kufuneka sibophe izinto eziphathekayo.
7.2 Indawo yokuhluma kufuneka ifakwe iziziba, ukuba isiphelo sendawo yomtya sibukhali, siya kuyisika ibe setyhula phambi kokuba imicu.
7.3 I-geomembrane kufuneka icolwe kwaye icoceke phambi kokuba ihlulwe.
7.4 Isixhobo sokudibanisa kufuneka sibe yinto enye kunye nemveliso yokugqibela kwaye isikwe ibe setyhula okanye i-ellipse.
8. HDPE Geomembrane anchorage
I-Anchorage groove (ubukhulu: 40cm * 40cm * 40cm), tsala i-geomembrane kwi-groove nge-U ebukhali kwaye uyilungise nge-sandbag okanye ikhonkrithi.
9. Indlela yokukhusela
Ukukhusela i-geomembrane ye-HDPE, siya kusebenzisa iindlela ezingezantsi:
9.1 Gaba enye i-geotextile ngaphezulu kwe-geomembrane uze ulungise isanti okanye umhlaba.
9.2 Gabha umhlaba okanye ikhonkrithi kwaye uhombise.
