Geotextile txheej txheem ntau lawm
Geotextile yog dav siv nyob rau hauv civil engineering cov ntaub ntawv, nrog rau pom, cais, qhov cuab lub zog, kev tiv thaiv thiab lwm yam functions, nws cov txheej txheem ntau lawm muaj xws li raw khoom npaj, yaj extrusion, mesh dov, cua ntsawj ntshab curing, winding ntim thiab soj ntsuam cov kauj ruam, yuav tsum mus los ntawm ntau yam kev sib txuas. ntawm kev ua thiab tswj, tab sis kuj yuav tsum xav txog nws ib puag ncig kev tiv thaiv thiab kav ntev thiab lwm yam. Cov cuab yeej tsim khoom niaj hnub thiab thev naus laus zis tau siv dav, ua rau kev tsim khoom thiab kev ua haujlwm zoo ntawm geotextiles tau zoo tuaj.
1. Raw khoom npaj
Cov ntaub ntawv tseem ceeb ntawm geotextile yog polyester chips, polypropylene filament thiab viscose fiber. Cov khoom siv raw yuav tsum tau kuaj xyuas, npaj thiab khaws cia kom ntseeg tau tias lawv zoo thiab ruaj khov.
2. Melt extrusion
Tom qab cov hlais polyester yog yaj ntawm qhov kub thiab txias, nws yog extruded rau hauv lub xeev molten los ntawm ib tug ntsia hlau extruder, thiab polypropylene filament thiab viscose fiber yog ntxiv rau nws. Nyob rau hauv cov txheej txheem no, qhov kub thiab txias, siab thiab lwm yam tsis yuav tsum tau precisely tswj kom lub uniformity thiab stability ntawm melting lub xeev.
3. Yob lub vas
Tom qab sib tov, cov yaj yog txau los ntawm cov spinneret los tsim cov tshuaj fiber ntau thiab tsim cov qauv sib xws ntawm txoj siv conveyor. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog los tswj lub thickness, uniformity thiab fiber ntau orientation ntawm lub mesh kom paub meej lub cev thiab stability ntawm geotextile.
4. Draft curing
Tom qab nteg lub net rau hauv yob, nws yog ib qhov tsim nyog los nqa tawm kev kho cua sov. Nyob rau hauv cov txheej txheem no, qhov kub, ceev thiab cov qauv piv txwv yuav tsum tau tswj kom meej meej lub zog thiab ruaj khov ntawm geotextile.
5. yob thiab ntim
Lub geotextile tom qab kev kho cua sov yuav tsum tau dov thiab ntim rau kev tsim kho tom ntej. Hauv cov txheej txheem no, qhov ntev, dav thiab tuab ntawm geotextile yuav tsum tau ntsuas kom ntseeg tau tias nws ua tau raws li cov qauv tsim.
6. Kev tshuaj xyuas zoo
Thaum kawg ntawm txhua qhov txuas txuas, qhov zoo ntawm geotextile yuav tsum tau kuaj xyuas. Cov ntsiab lus tshuaj xyuas muaj xws li kuaj cov cuab yeej ntawm lub cev, kuaj cov khoom siv tshuaj lom neeg thiab kuaj pom qhov zoo. Tsuas yog geotextiles uas ua tau raws li qhov yuav tsum tau ua zoo tuaj yeem siv hauv khw.
