Cov txheej txheem tsim khoom Geotextile
Geotextile siv dav hauv cov ntaub ntawv engineering civil, nrog rau kev lim dej, kev rho tawm, kev txhawb zog, kev tiv thaiv thiab lwm yam haujlwm, nws cov txheej txheem ntau lawm suav nrog kev npaj cov khoom siv raw, yaj extrusion, mesh dov, cua ntsawj kho, winding ntim thiab cov kauj ruam tshuaj xyuas, yuav tsum tau mus dhau ntau qhov txuas ntawm kev ua thiab kev tswj hwm, tab sis kuj yuav tsum xav txog nws txoj kev tiv thaiv ib puag ncig thiab kev ruaj khov thiab lwm yam. Cov khoom siv niaj hnub tsim khoom thiab thev naus laus zis tau siv dav, ua rau kev ua haujlwm zoo thiab qhov zoo ntawm geotextiles tau zoo dua.
1. Kev npaj cov khoom siv raw
Cov ntaub ntawv tseem ceeb ntawm geotextile yog polyester chips, polypropylene filament thiab viscose fiber. Cov ntaub ntawv raw no yuav tsum tau kuaj xyuas, npaj thiab khaws cia kom ntseeg tau tias lawv zoo thiab ruaj khov.
2. Yaj cov extrusion
Tom qab cov polyester slice yaj ntawm qhov kub siab, nws raug extruded rau hauv lub xeev molten los ntawm lub tshuab extruder ntsia hlau, thiab polypropylene filament thiab viscose fiber ntxiv rau kev sib tov. Hauv cov txheej txheem no, qhov kub, siab thiab lwm yam kev ntsuas yuav tsum tau tswj hwm kom meej kom ntseeg tau tias qhov sib xws thiab ruaj khov ntawm lub xeev melting.
3. Dov lub vas
Tom qab sib tov, cov yaj raug txau los ntawm lub spinneret los tsim cov khoom siv fibrous thiab tsim cov qauv sib xws ntawm txoj siv conveyor. Lub sijhawm no, nws yog qhov tsim nyog los tswj qhov tuab, sib xws thiab kev taw qhia fiber ntawm lub mesh kom ntseeg tau tias cov khoom siv lub cev thiab kev ruaj khov ntawm geotextile.
4. Kev kho cua sov
Tom qab muab lub vas tso ua tej daim me me lawm, yuav tsum tau ua kom cov cua ntsawj kom qhuav. Hauv cov txheej txheem no, qhov kub, qhov ceev thiab qhov piv ntawm cov cua ntsawj yuav tsum tau tswj kom meej kom ntseeg tau tias lub geotextile muaj zog thiab ruaj khov.
5. Yob thiab ntim khoom
Tom qab cov cua ntsawj kho lawm, yuav tsum tau dov thiab ntim rau kev tsim kho tom ntej. Hauv cov txheej txheem no, yuav tsum ntsuas qhov ntev, dav thiab tuab ntawm cov geotextile kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau ua.
6. Kev tshuaj xyuas zoo
Thaum kawg ntawm txhua qhov txuas ntau lawm, qhov zoo ntawm geotextile yuav tsum tau kuaj xyuas. Cov ntsiab lus tshuaj xyuas suav nrog kev sim khoom siv lub cev, kev sim khoom siv tshuaj lom neeg thiab kev sim zoo li cas. Tsuas yog geotextiles uas ua tau raws li qhov yuav tsum tau ua zoo thiaj li siv tau hauv kev ua lag luam.
