Onse HDPE: chimene icho chiri, katundu ndi ntchito

Geomembranes ndi amakono mpukutu polymeric zipangizo, amene akhoza zimasiyana ndi makulidwe a mamilimita 1 mpaka 4. Amachita wa polyethylene, polypropylene, polyvinyl mankhwala enaake ndi zipangizo zina ndi makulidwe osachepera 0.5 mm. Pankhani m'lifupi, ndiye kungakhale kwa 7 m, ndi zofunika opaleshoni khalidwe ndi kuti geomembrane kwathunthu madzi. Ndi zambiri kuchuluka kwa ntchito yake, yomwe ndi Inter zina zotere, tikambirana pansipa.

katundu

Masiku ano sizachilendo geomembrane HDPE, chimene icho chiri, adzakhululukidwa anafotokoza m'nkhani. Modern geomembrane pamaziko a polyethylene akhoza kukhala textured kapena yosalala pamwamba. Izi adzalola kuti agwiritse ntchito kusankha mu ntchito ya mtundu wa ntchito. Mwa makhalidwe chachikulu cha zinthu izi zikhoza olekanitsidwa makhalidwe mkulu kumatira. zomangira ndi mkulu thupi katundu ndi makina, zomwe zimawachititsa mosalekeza. Pamene iwo ali mu kukhudzana ndi zakumwa, ndondomeko mayamwidwe zitha kumachitika pa mlingo maselo. Ndi momwe Tingaone kuti zinthu zikhoza kugwiritsidwa ntchito mogwirizana mwachindunji ndi madzi. Geomembranes ndi kugonjetsedwa ndi mankhwala, ali azithunzi omwe tikunena bata, kugawa pasakhale ming'alu ndi kubatizidwa mitundu yonse ya chikoka chachikulu, popanda kuwononga iwo. Zofunika elongates mchikakamizo cha katundu ndi 850%, ndi kwamakokedwe mphamvu zake kukhala wolingana 26,2 MPa.

kuvala makhalidwe

Ngati mukufuna geomembrane HDPE, chimene icho chiri, inu mwamtheradi ayenera kudziwa. Nkhanizi kugonjetsedwa ndi cheza dzuwa, kusiyana kutentha, ndipo Angagwiritsidwenso ntchito mu mabacteria zivomerezi. Ndi kugonjetsedwa puncture ndipo angagwiritsidwe ntchito zosiyanasiyana ntchito. Ntchito geomembrane akhoza kukhala mabacteria onse nyengo. Ngati mutsatira malamulo a unsembe akatswiri moyo opaleshoni ya geomembrane kungakhale kwa zaka 90.

Kuchuluka kwa ntchito

Mu zaka zapitazo, likupitirirabe ambiri amagwiritsa ntchito geomembrane HDPE. Nchiyani, pamaso kugula muyenera kufunsa. Nkhanizi ali kwambiri maonekedwe ndi mankhwala umenewu ndi kuthekera ntchito kusinthika zowonetsera Anachita kusonkhanitsa zinyalala madzi ndi olimba akhoza zimachitika pano ndi poizoni. Geomembrane advantageously ntchito mu kusinthika mayiwe, landfills, manyowa ndi kumatira ❖ kuyanika wa zitsulo anticorrosive konkire ndi nyumba zina, ndipo mwina kucheza ndi madzi abwino pa ntchito. Akugulitsa mungapeze mitundu yambiri ya geomembrane HDPE: Solmax 840, 860 ndi 880. Aliyense wa zinthuzi - makhalidwe awo zizindikiro zina. Mwachitsanzo, osachepera pafupifupi makulidwe a yoyamba 1 mm, pomwe wachiwiri ndi wachitatu - 1.5 ndi 2 mm, motero. kukula mayina ndi 6,8x238; 6,8x159; 6,8x122 mm, motero, aliyense wa mitundu imeneyi.

kachulukidwe

The kachulukidwe zinthu milandu itatu yonse ndi chimodzimodzi, ndipo angayambe ku 0,926 g / cm². Monga kachulukidwe zonse nembanemba, zikhonza kukhala wolingana 0,939 g / cm², mtengo uwu ndi zina zambiri. Okhutira mpweya lakuda lingayambire pakukhala 2 3%. Voteji-zakuthupi ndi elongation angakhale ofanana kwa 14,7; 22 kapena 29%, motero.

katundu zina

omanga Professional ndi amisiri kunyumba ntchito HDPE geomembrane, - chimene icho chiri, inu muyenera kufunsa pamaso kugula. Nkhanizi zambiri ubwino, pakati pawo - ndi ntchito zake zosiyanasiyana, dzuwa, mkulu kukhazikitsidwa workability, dzuwa ndi waubwenzi zachilengedwe. Zinchito khalidwe geomembrane kupereka ankafuna kumanga nyumba kwa kusungiramo ngozi kungotaya magulu osiyanasiyana. geomembrane amenewa ntchito mu malo ndi zomangamanga hayidiroliki. Zofunika ndi ndalama, ntchito yake kumachepetsa mtengo wa ntchito ndi kumanga. Ziribe kanthu zomwe dera ntchito, ntchito geomembranes amachepetsa chiwerengero cha ntchito, kuchuluka kwa katundu, ndipo amalola kuti kumaliza ntchitoyo posachedwapa. HDPE geomembrane wotchuka mkulu kuika processability nayenso. Amakhala mu m'lifupi mamita 7 yafupika kufunika seams uja zida kuwotcherera. Choncho, aluso alibe kusowa kuchita seams Buku pa mfundo mapanelo.

Geomembranes ndi cholimba kwambiri ndi odalirika ntchito. Njira akupangidwa ndi khalidwe ndi kwa ndime. Mwazina, zinthu kwathunthu wochezeka. Izo ntchito mu kusinthika kwa maofesi zoteteza chilengedwe. Kuchokera pa specifications, ndi zotheka kuti zimatsimikizira kudzipatula nyumba odalirika, amene silikuphatikiza wa mayamwidwe magwero kuipitsa.

Features ya ntchito kuti: siteji kukonzekera

HDPE (polyethylene) ayenera kuikidwa pa maziko okonzeka, amene kale achotse miyala, zinyalala, organics ndi zipangizo zina zomwe angathe kuwononga nsalu. Zimachitika kuti pamwamba si akwaniritsa zofunikira pamwamba, mu milandu Ndi bwino kugwiritsa ntchito amabweretsera wosanjikiza zoteteza, chomwe ndi nsalu needled. Nkofunika kukhwimitsa kuti kodi kukusalani Mwina m'madera a kudzikundikira madzimadzi pa padziko amabweretsera wosanjikiza.

Kuika zinthu

Pa mtima wa geotextile wa - HDPE. HDPE ayenera kuikidwa mogwirizana ndi malamulo, amene sizingasutsane ndi chikhalidwe cha nkhaniyi. Muyenera kuyamba ntchito pambuyo yokonza ndondomeko unsembe. Mwatsatanetsatane zimenezi zimasonyeza kukula ndi wachibale udindo wa zojambula, komanso welds. Unsembe ntchito pazikhalanso kusunga zinthu zina, pakati pawo - malangizo ndi ndondomeko ya unsembe, chodetsa mapanelo ndi welded mafupa, malo a nyumba za mtundu wa ulimi wa mapaipi ndi kugwirizana kwa nyumba alipo. mapepala ayenera pabwino kuti matabwa sanali anawoloka pa nthawi ina. Cm osachepera pakati pa tigwirizane ayenera kukhala 0.5 mamita HDPE (mkulu osalimba polyethylene - maziko a zinthu). Kodi alipo mwa m'lifupi mu osiyanasiyana kuchokera mamilimita 100 mpaka 150. Kulimbikira lamulo limeneli ayenera kukhala mu yopingasa malangizo ndi kotenga. Master ayenera kuonetsetsa mlingo wa welds yotentha ndi ndondomeko ndi extrusion.

M'mbali mwa chuma ayenera zakhala zikuzunza m'miyoyo kuchokera pamwamba mpaka pansi, motero m'pofunika ntchito chipangizo wakupambulika dzinache traverses. ayenera kupereka pamaso nangula kukonza ngalande geomembrane pamwamba pa otsetsereka pamwamba. Ngati pali kufunika kulimbikitsa geomembrane pamwamba simenti, ndi zofunika kukonzeketsera yolusa zinthu zapadera, kungakhale mbale kuthamanga ndi dowels, geomembrane n'kupanga. pasadakhale Recent ayenera Ufumuyo padziko anangula konkire. Monga fasteners akhoza kuchita ndi oyika.

Malangizo kwa kuwotcherera

Kodi inu geomembrane zomvetsera kuti ntchito - HDPE 1,5 mamilimita kapena makulidwe ina, matabwa kuwotcherera ziyenera kuperekedwa ndi zipangizo zina zapadera, umene umabala mpweya wotentha. An chimake zina akhoza kuchita mphero otentha kapena njira pamodzi. Njira otsiriza amalola kuchita ziwiri msoko, umene ndi mosamala njira. Kenako kuti athe kulamulira khalidwe la china chotulutsa olowa. Ngati tili kugwira ntchito mipata sachoka kapena malo a zofunikira, ndi bwino kugwiritsa ntchito luso extrusion kuwotcherera.

m'malo mapeto

HDPE kachulukidwe umene zochulidwa pamwamba, zikhoza kukhala chidwi osati akatswiri komanso wofikapo nyumba ambuye, amene akonza ntchito mfundo ntchito. Mwazina, mukakhale chidwi ena apadera katundu wa geomembranes. Pakati pawo ndi kupereka ndi inertness kuti alkalis ndi zidulo, omwe pH mu osiyanasiyana 1.5 mpaka 14. Zochita, mmene matenthedwe kukalamba zimachokeradi, koma muyezo chitsimikizo pa mfundo kudziletsa unsembe ndi zaka 75.
