filament spunbond ndi singano nonwoven geotextiles
Mafotokozedwe Akatundu
Mitundu ya geotextiles:Filament geotextiles ndi poliyesitala ulusi wokhomeredwa ndi singano wosaluka wa geotextiles, womwe ulibe zowonjezera mankhwala komanso osatenthedwa.Ndi zipangizo zomangira zachilengedwe.Itha kulowa m'malo mwa zida zamauinjiniya ndi njira zomangira, kupanga zomanga kukhala zotetezeka, kuthandizira kuteteza chilengedwe, ndikuthetsa zovuta zoyambira pakumanga uinjiniya mwachuma, mogwira mtima komanso mokhalitsa.
Filament geotextile ili ndi ntchito yabwino yamakina, kutsekemera kwa madzi abwino, anti-corrosion, anti-kukalamba, ndipo ili ndi ntchito zodzipatula, zotsutsana ndi kusefera, ngalande, chitetezo, kukhazikika, kulimbikitsa, etc. Kuwonongeka, kukwawa ndi kochepa, ndi ntchito yoyambirira. ikhoza kusungidwabe pansi pa katundu wautali.
Makhalidwe a geotextile:
Mphamvu - Pansi pa kulemera kwa gilamu komweko, mphamvu zamakokedwe mbali zonse ndizokwera kuposa singano zina zokhomeredwa ndi nsalu zosalukidwa.
Anti-ultraviolet kuwala - ali kwambiri odana ndi ultraviolet mphamvu.
Kukana kutentha kwambiri - kukana kutentha kwambiri mpaka 230 ℃, mawonekedwe ake amakhalabe osasunthika ndipo zida zoyambira zimasungidwabe kutentha kwambiri.
Kuthekera ndi Kugwetsa kwa Ndege - Geotextile ndi yokhuthala ndipo singano imakhomeredwa ndipo imakhala ndi ngalande zabwino zandege komanso kupindika kwamadzi, komwe kumatha kusungidwa kwa zaka zambiri.
Kukana kwa Creep - Kukaniza kwa ma geotextiles ndikwabwino kuposa ma geotextiles ena, kotero zotsatira zake zazitali ndizabwino.Ndi kugonjetsedwa ndi kukokoloka kwa mankhwala wamba mu nthaka ndi dzimbiri mafuta, dizilo, etc.
Kutalikirana - ma geotextiles amakhala ndi kutalika kwabwino pansi pa kupsinjika kwina, kuwapangitsa kuti azitha kusintha malo osalingana komanso osakhazikika.
Makhalidwe aukadaulo a ma filament geotextiles: Ma geotextiles okhuthala amatha kuwonetsetsa kuti ma geotextiles ali ndi mbali zitatu, zomwe zimathandizira kukwaniritsidwa kwa zinthu zabwino kwambiri zama hydraulic.
Kuphulika kwamphamvu kwa geotextile kuli ndi zabwino zambiri, makamaka zoyenera kusunga khoma ndi kulimbikitsa mpanda.Ma index a geotextiles onse amaposa miyezo ya dziko lonse ndipo ndi zida zolimbikitsira za geotechnical.
Ichi ndi geotextile yokhala ndi ma pores atatu-dimensional opangidwa kuchokera ku PET kapena PP ndi kusungunula kupota, kuyika mpweya, ndi njira zophatikizira zokhomeredwa ndi singano.
Chiyambi cha Zamalonda
Mafotokozedwe a Zamalonda
Kulemera kwa gramu ndi 100g/㎡～800g/㎡;m'lifupi ndi 4 ~ 6.4 mamita, ndipo kutalika ndi malinga ndi zosowa za makasitomala.
Zogulitsa Zamalonda
Mlozera wapamwamba wamakina, magwiridwe antchito abwino;kukana kwamphamvu kwa dzimbiri, kukana kukalamba, kukana kutentha kwambiri, komanso magwiridwe antchito abwino a hydraulic.
Zochitika za Ntchito
Amagwiritsidwa ntchito makamaka kulimbikitsa, kusefera, kudzipatula komanso kukhetsa madzi osungira madzi,mphamvu yamadzi, kuteteza chilengedwe, misewu yayikulu, njanji, madamu, magombe amphepete mwa nyanja, migodi yazitsulo ndi ntchito zina.
