PET Filament Singeing Geotextile

Filament singeing Geotextile

 

Filament hu nkauj Geotextile yog ib hom tshiab ntawm geotextile zoo heev rau kev ntxiv dag zog rau pavement thiab subgrade. Cov khoom no yog ua los ntawm polyester viscose filament Geotextile singeing ntawm ib sab. Nws muaj lub zog tensile siab nyob rau hauv ob qho tib si kab rov tav thiab ntsug cov lus qhia, siab elastic modulus, thiab zoo heev tsis kam mus rau siab thiab tsis kub. Tom qab txheej txheej txheej txheej, nws muaj kev ua haujlwm zoo alkali thiab kev laus ua haujlwm, thiab yog dav siv rau kev txhim kho ntawm asphalt pavement, cement qhob pavement, thiab roadbed. Ob qho tib si nyuaj thiab hloov tau yooj yim ntawm txoj kev yog qhov tsim nyog, uas tuaj yeem txo tus nqi, txuas ntxiv kev pab cuam lub neej, thiab tiv thaiv kev cuam tshuam ntawm kev sib tsoo piv rau cov chaw ntawm txoj kev.

 

1, Singeing Geotextile khoom specification

2-6 meters dav

50-100 meters ntev

Qhov hnyav: 100-800 grams/square meter

2, Singeing Geotextile khoom kev ua tau zoo

1. Cov khoom no yog tsim los ntawm 100 feem pua ​​​​polyester, nrog lub melting point ntawm tshaj 260 degree thiab tsis muaj qhov tseem ceeb shrinkage hauv qab 230 degree. Xaiv cov khoom no tuaj yeem zam lub peev xwm thermal shrinkage ntawm cov ntaub ntawm qhov kub thiab txias thaum paving kub asphalt txheej txheej;

2. Cov khoom no yog non-woven Geotextile ua los ntawm polyester nruam filament reinforced los ntawm koob punching. Nws lub zog tensile ntau dua los yog sib npaug rau 8KN / m, thiab nws qhov elongation yog 40-60 feem pua, uas ua tau raws li cov kev cai rau Geotextile hauv JTJ/T019-98 (Technical Specification for Application of Highway Geosynthetics) ;

3. Cov khoom no muaj ib tug nruab nrab thickness thiab muaj zog muaj peev xwm impregnate asphalt. Nws ua ke nrog cov roj txheej qhuav los tsim cov txheej txheem kev sib cais zoo tshaj plaws thiab muaj cov dej tsis zoo thiab rwb thaiv tsev zoo;

4. Cov khoom no muaj peev xwm tiv taus hluav taws xob ultraviolet, txias txias, tshuaj corrosion, thiab kev puas tsuaj lom;

5. Cov khoom no yog tsim rau txoj kev nto thiab muaj ib tug tshwj xeeb patent rau ib leeg thiab ob sab singeing. Thaum nteg, sab ntxhib ntawm singeing yog tig mus rau sab saud, uas tsis tsuas yog txhim kho lub zog sib txuas ntawm cov txheej txheej saum npoo thiab cov interlayer, tab sis kuj tiv thaiv kom tsis txhob raug dov thiab puas los ntawm lub log thaum siv. Nyob rau tib lub sijhawm, nws tuaj yeem cuam tshuam qhov tshwm sim ntawm lub tsheb thiab pavers ntawm daim ntaub;

6. Txo lub zog sib txuas ntawm cov txheej txheej saum npoo thiab interlayer;

7. Tshem tawm kev ntxhov siab ntawm qhov tawg thiab tiv thaiv kev tawg;

8. Tom qab impregnating nrog asphalt, nws dhau los ua ib txheej impermeable los tiv thaiv dej los ntawm softening txoj kev qauv.

3, Siv cov khoom siv geotextile singeing

1. Kev cais tawm

Siv Geotextile los cais cov khoom siv hauv tsev (xws li av thiab xuab zeb, xuab zeb thiab pob zeb, av thiab pob zeb) nrog cov khoom sib txawv ntawm lub cev (qhov loj me me, faib, sib xws thiab ntom, thiab lwm yam). Xyuas kom meej tias tsis muaj kev poob lossis sib xyaw ntawm ob hom khoom siv, tswj xyuas tag nrho cov qauv thiab kev ua haujlwm ntawm cov ntaub ntawv, thiab txhim kho lub peev xwm thauj khoom ntawm cov qauv;

2. Lim

Thaum cov txheej av zoo ntws mus rau hauv cov txheej txheej txheej txheej, cov koob punched Geotextile nrog cov huab cua zoo permeability thiab dej permeability yog siv los ua kom cov dej ntws los ntawm, thiab cov av hais, xuab zeb zoo, pob zeb me me, thiab lwm yam. stability ntawm dej thiab av engineering;

3. Cov dej ntws tawm

Geotextile yog cov khoom siv dej zoo, uas tuaj yeem tsim cov dej ntws hauv cov av hauv lub cev kom ntws cov kua dej ntau dhau hauv cov qauv av;

4. Kev txhawb zog

Needle punched Geotextile tuaj yeem txhim kho lub zog tensile thiab deformation tsis kam ntawm cov av, ua kom muaj kev ruaj ntseg ntawm lub tsev, thiab txhim kho cov av zoo;

5. Kev tiv thaiv

Tshaj tawm, hloov mus, los yog decompose concentrated kev nyuaj siab los tiv thaiv kev puas tsuaj rau daim duab vim yog sab nraud quab yuam;

6. Kaw

Geotextile tau ua ke nrog lwm cov ntaub ntawv (tsuas yog asphalt lossis yas zaj duab xis) los tsim ib qho impermeable barrier hauv av txheej. (Siv rau txoj kev resurfacing thiab kho, thiab lwm yam).

Singeing Geotextile feem ntau yog siv rau:

1. Water conservancy engineering: seawall, dej embankment, thiab pas dej embankment ua raws li engineering; Reservoir reinforcement engineering; Reclamation tej yaam num; Kev tiv thaiv dej nyab thiab cawm;

2. Txoj kev loj, railway, thiab tshav dav hlau engineering: soft foundation reinforcement kho, txoj kab nqes kev tiv thaiv, pavement anti reflection crack structural txheej, kua system, thiab ntsuab cais txoj siv;

3. Hluav taws xob engineering: nuclear fais fab nroj tsuag foundation engineering, thermal hwj chim tshauv dam engineering, hydropower chaw nres tsheb engineering;

4. Chaw nres nkoj dej engineering: Chaw nres nkoj.
