Ntau tus neeg muas zaub los ntawm peb lub vev xaib hauv xov tooj los tham txog hom woven hnab thiab daim ntawv thov ntau yam, uas niaj hnub dongle woven hnab xiaobian piav qhia txog hom woven hnab thiab daim ntawv thov ntau yam.
Knitted hnab kuj hu ua snakeskin hnab. Nws yog yas, feem ntau yog siv rau ntim. Nws cov ntaub ntawv raw yog feem ntau polyethylene, polypropylene thiab lwm yam khoom siv yas raw khoom. Hauv qab no yog ib qho kev qhia txog hom thiab kev siv ntawm cov hnab woven.
hom
Cov khoom siv tseem ceeb rau kev tsim tawm txawv teb chaws yog polyethylene (PE), thaum cov khoom tseem ceeb rau kev tsim khoom hauv tsev yog polypropylene (PP), thermoplastic resin npaj los ntawm ethylene polymerization. Industrially, copolymer ntawm ethylene nrog me me ntawm -olefin kuj suav nrog. Tsis muaj ntxhiab, tsis muaj tshuaj lom, waxy polyethylene, nrog rau qhov kub thiab txias tsis kam (tsawg kawg ua haujlwm kub txog -70 ~ 100 ℃), tshuaj lom neeg ruaj khov, tsis kam rau feem ntau cov kua qaub thiab alkali corrosion (oxidation resistant acid), insoluble nyob rau hauv cov kuab tshuaj nyob rau hauv chav tsev kub, tsis tshua muaj dej nqus, zoo heev hluav taws xob rwb thaiv tsev kev ua tau zoo; Nws yog polyethylene (tshuaj lom neeg thiab hluav taws xob rwb thaiv tsev) rau ib puag ncig kev ntxhov siab; Mechanical nyhuv) rhiab heev, tsis zoo tiv thaiv tshav kub laus. Cov khoom ntawm polyethylene sib txawv ntawm hom mus rau hom, feem ntau nyob ntawm nws cov qauv molecular thiab ntom. Cov khoom uas muaj qhov sib txawv (0.91 txog 0.96 g / cm3) tuaj yeem tau txais los ntawm ntau txoj hauv kev. Polyethylene tuaj yeem ua tiav los ntawm cov txheej txheem thermoplastic ntau lawm (saib Plastic processing ). Siv dav hauv kev tsim cov yeeb yaj kiab, ntim khoom, cov kav dej, ib leeg xaim, xaim thiab cable, khoom siv txhua hnub, thiab lwm yam. Nws kuj tseem siv tau los ua cov khoom siv hluav taws xob ntau zaus rau TV thiab radar. Nrog rau kev txhim kho ntawm kev lag luam petrochemical, polyethylene ntau lawm tau tsim sai heev, suav txog li ib feem peb ntawm tag nrho cov khoom yas. Xyoo 1983, lub ntiaj teb tag nrho cov peev txheej ntawm polyethylene yog 24.65 Mt, thiab lub peev xwm ntawm cov nroj tsuag hauv kev tsim kho yog 3.16 Mt.
polypropylene
Thermoplastic resin npaj los ntawm propylene polymerization. Muaj peb qhov kev teeb tsa ntawm tag nrho isomorphism, random thiab interisomorphism. Cov khoom tseem ceeb ntawm cov khoom lag luam yog homogenous tshuaj. Polypropylene kuj suav nrog copolymer ntawm propylene thiab ib qho me me ntawm ethylene. Nws feem ntau yog cov khoom tsis muaj xim tsis muaj xim, tsis qab thiab tsis muaj tshuaj lom. Vim nws cov qauv tsis tu ncua thiab siab crystallinity, lub melting point yog mus txog 167 ℃. Nws yog kub resistant thiab cov khoom yuav sterilized los ntawm chav. Qhov ntom ntawm 0.90 g / cm3 yog lub teeb tshaj plaws universal yas. Corrosion kuj, tensile zog 30 MPa, lub zog, rigidity thiab pob tshab yog zoo dua li polyethylene. Qhov tsis zoo yog qhov cuam tshuam tsis zoo thiab kev laus yooj yim ntawm qhov kub thiab txias, uas tuaj yeem kov yeej los ntawm kev hloov kho thiab ntxiv cov tshuaj antioxidants feem.
Cov xim ntawm cov hnab woven feem ntau yog dawb lossis dawb, tsis muaj tshuaj lom thiab tsis qab, feem ntau tsis muaj teeb meem rau tib neeg lub cev. Txawm hais tias lawv yog tsim los ntawm ntau hom tshuaj yas, lawv yog ib puag ncig zoo thiab rov ua dua tshiab.
Woven hnab yog dav siv, feem ntau yog rau ntim ntau yam khoom, thiab dav siv nyob rau hauv kev lag luam.
Lub hnab yas woven yog ua los ntawm polypropylene resin, extruded thiab stretched rau hauv ca lo lo ntxhuav, thiab ces woven rau hauv hnab.
Cov hnab yas sib xyaw ua ke yog ua los ntawm cov ntaub yas los ntawm cov kwj deg.
Siv los ntim cov hmoov los yog cov khoom siv granular thiab cov khoom siv tau yooj yim. Lub hnab yas sib xyaw ua ke muab faib ua ob lub hnab hauv ib lub hnab thiab peb lub hnab hauv ib lub hnab raws li cov khoom siv tseem ceeb.
Raws li txoj kev xaws, nws tuaj yeem muab faib ua lub hnab xaws hauv qab, xaws ntug hnab, ntxig lub hnab thiab khi lub hnab xaws.
Nyob ntawm qhov dav dav ntawm lub hnab, nws tuaj yeem muab faib ua 450, 500, 550, 600, 650 thiab 700 mm. Tshwj xeeb specifications tau pom zoo los ntawm tus neeg muag khoom thiab cov neeg siv khoom.
Ntau qhov kev thov
1. Ntim hnab rau cov khoom lag luam thiab kev ua liaj ua teb
Nrog rau kev txhim kho thiab kev siv cov hnab ntim khoom siv tau yooj yim, cov hnab yas woven ntim tau dav siv hauv Marine, kev thauj mus los thiab ntim kev lag luam thiab cov khoom ua liaj ua teb.

Cov ntaub ntawv engineering
Txij li thaum txoj kev loj hlob ntawm geotextile nyob rau hauv lub 80s, daim ntawv thov teb ntawm yas woven npuag tau nthuav, dav siv nyob rau hauv me me kev txuag dej, hluav taws xob fais fab, txoj kev loj, railway, chaw nres nkoj, mine kev tsim kho thiab kev ua tub rog. Hauv cov haujlwm no, geosynthetics muaj cov haujlwm ntawm kev pom, kev tso dej, kev txhawb zog, kev sib cais thiab kev tswj xyuas qhov dej. Yas geotextiles yog ib qho ntawm cov hluavtaws geotextiles.
Cov khoom siv tswj dej nyab
Woven hnab yog qhov tseem ceeb rau kev tswj dej nyab. Lawv kuj tseem yog qhov tseem ceeb hauv kev tsim kho ntawm embankments, dej ntws, railways thiab txoj kev. Lawv yog cov tshuaj tiv thaiv - cov ntaub ntawv woven hnab, anti - drought woven hnab thiab anti - dej nyab woven hnab.
Saum toj no yog me me ua rau txhua tus neeg ua tiav ntawm cov hnab ntim khoom thiab cov peev txheej ntawm daim ntawv thov kev sib tham txog kev sib tham, los ntawm kev sib koom ntawm cov ntsiab lus, hom thiab daim ntawv thov ntau yam ntawm cov hnab woven muaj qee yam kev txawj ntse, yog tias koj xav mus tob rau hauv lub hnab ntawm cov ntaub ntawv kev ua lag luam, tuaj yeem tiv tauj tus neeg muag khoom hauv peb lub tuam txhab, lossis mus rau sab hnub tuaj thiab lub hnab ntim khoom ntawm qhov chaw tshawb nrhiav, kev sib txuas lus ntawm daim ntawv no.
