Kodi polyester yopanda nsalu ndi chiyani

Nsalu ya polyester yopanda nsaluNthawi zambiri amatanthauza nsalu ya poliyesitala yopanda nsalu, ndipo dzina lenileni liyenera kukhala "nsalu yopanda nsalu". Ndi mtundu wa nsalu zopangidwa popanda kufunikira kwa kupota ndi kuluka. Imangoyang'ana kapena kusanja mwachisawawa ulusi waufupi wa nsalu kapena ulusi wautali kuti upangire maukonde a ulusi, kenaka amagwiritsa ntchito makina, kulumikizana kwamafuta, kapena njira zama mankhwala kuti azilimbitsa. Ndi mtundu watsopano wamtundu wa ulusi wokhala ndi mawonekedwe ofewa, opumira, komanso athyathyathya, omwe amapangidwa mwachindunji kudzera munjira zosiyanasiyana zopangira ma mesh ndi njira zophatikizira pogwiritsa ntchito ma polima apamwamba, ulusi wamfupi, kapena ulusi wautali.

Nsalu ya polyester nonwoven ndi nsalu yosalukidwa yomwe imapangidwa pogawira ulusi wofanana wa poliyesitala pa nsalu yotchinga ya mauna othamanga pansi pa kutentha kwapadera ndi kukakamizidwa kudzera pazida monga wononga extruder ndi spinneret, kupanga mauna a fluffy fiber, kenako kubowoledwa mobwerezabwereza ndi makina okhomerera singano. Nsalu ya polyester yopanda nsalu yopangidwa ndi Jiamei New Material ili ndi ntchito yabwino yamakina, kutsekemera kwamadzi, kukana dzimbiri, kukana kukalamba, kudzipatula, kusefera, ngalande, chitetezo, kukhazikika, kulimbitsa ndi ntchito zina, imatha kutengera njira yoyambira yosagwirizana, imatha kukana kuwonongeka kwa mphamvu yakunja pakumanga, kukwawa ndi kochepa, ndipo kumatha kukhalabe ndi ntchito yake yoyambirira, chifukwa chake imagwiritsidwa ntchito nthawi yayitali ngati madzi osanjikiza.

Poyerekeza ndi mitundu ina ya nsalu geotextiles ndi zazifupi fiber geotextiles,polyester yopanda nsaluali ndi izi:

(1) Mphamvu yolimba kwambiri: Poyerekeza ndi ma geotextiles amfupi a giredi lomwelo, mphamvu yamakomedwe imachulukitsidwa ndi 63%, kukana misozi kumawonjezeka ndi 79%, ndipo kukana kwapamwamba kumawonjezeka ndi 135%.

(2) Kukana kutentha kwabwino: Kumakhala ndi malo ochepetsera pamwamba pa 238 ℃, ndipo mphamvu yake sichepa pa 200 ℃. Kutentha kwa kutentha sikusintha pansi pa 2 ℃.

(3) Kuchita bwino kwambiri: Mphamvu sizidzatsika mwadzidzidzi mukamagwiritsa ntchito nthawi yayitali.

(4) Kukana kwamphamvu kwa dzimbiri.

(5) Kukhazikika kwabwino, etc.

Malo odzipatula osagwirizana ndi madzi alipo pakati pa denga lopanda madzi ndi lolimba loteteza pamwamba. Chosanjikiza chokhazikika pamtunda (nthawi zambiri 40mm wandiweyani wa konkriti wobiriwira) chidzakulitsa matenthedwe ndikupindika. Mukapanga zigawo zina pansanjika yosalowerera madzi, pofuna kupewa kuwononga wosanjikiza wosanjikiza madzi, nsalu ya polyester yopanda nsalu nthawi zambiri imapangidwa kuti itetezedwe moyenera, yolemera 200g/㎡. Nsalu ya poliyesitala yosalukidwa nthawi zambiri imakhala yobowoleza komanso yolowera, yomwe imatha kutolera madzi ndikutulutsa m'nthaka ikakwiriridwamo. Iwo sangakhoze kokha kukhetsa motsatira njira perpendicular kwa ndege yawo, komanso motsatira malangizo awo ndege, kutanthauza kuti ndi yopingasa ngalande ntchito. Ma filament geotextiles aatali akhala akugwiritsidwa ntchito kwambiri kukhetsa ndi kuphatikiza madamu a nthaka, misewu, makoma osungira, ndi maziko a nthaka yofewa. Nsalu ya polyester yosalukidwa imakhala ndi mphamvu zolimba kwambiri, kukana kutentha kwabwino, kuyendetsa bwino kwambiri, komanso kukana dzimbiri mwamphamvu. Kukhalitsa kwabwino, porosity yayikulu, komanso ma hydraulic conductivity ndi zida zoyenera zosefera nthaka. Choncho, amagwiritsidwa ntchito kwambiri m'mabwalo opangira denga, misewu ya asphalt, milatho, kusunga madzi ndi ntchito zina zomanga.
