Qhov hnyav ntawm gram sib raug rau qhov tuab ntawm geotextile npaum li cas?
Qhov hnyav ntawmgeotextilenws txawv ntawm 100g txog 1000g ib square meter. Vim tias nws yog cov ntaub tsis-woven ua los ntawm kev siv koob ntau zaus, nws tsis yooj yim sua kom txiav txim siab tias nws tuab npaum li cas los ntawm kev kov tes, thiab yuav tsum siv cov cuab yeej ntsuas tuab tshwj xeeb uas tsis yog woven los ntsuas nws.
Yog li 100 grams ntawm cov ntaub hnyav uas tsis yog-woven tuab yuav ua li cas xam?
Cov lus teb yog tsis muaj peev xwm suav tau. Peb tsuas yog ua tau raws li cov cim qhia txog geotextile los txiav txim siab nws cov g, 100 g cov ntaub tsis-woven thiab cov ntaub luv luv thiab cov ntaub filament, txawm hais tias ob qho tib si yog 100 grams, tab sis qhov tuab sib txawv, qhov tuab ntawm cov ntaub luv luv 100 g hauv 0.9 hli (millimeter), thaum cov filament hauv 0.8 hli, tau kawg, yuav muaj 2% txog 3% qhov yuam kev, vim tias ntau hom khoom siv thiab kev ua haujlwm thev naus laus zis sib txawv, yog li tsis tuaj yeem zam qhov muaj qhov yuam kev.
Cov geotextiles uas tsis yog woven puas tuaj yeem ua kom sov tau?
Vim tiascov ntaub tsis yog wovenyog ua los ntawm lub zog siab thiab tiv thaiv kev laus polyester fiber lossis polypropylene thiab polyester chips ua cov ntaub ntawv raw los ntawm kev ua tshwj xeeb, yog li nws muaj kev tiv thaiv corrosion zoo, acid thiab alkali tsis kam, tawg zog thiab frost thawing tsis kam.
Piv txwv li, thaum tsim lub tsev cog khoom txias rwb thaiv tsev, daim ntaub tsis-woven tuaj yeem hloov pauv tag nrho kev siv cov ntaub mos, tso yooj yim, txuag lub sijhawm thiab kev siv zog; Hais txog kev rwb thaiv tsev ru tsev, lub tsev rwb thaiv tsev ib txwm yog los tsim ib txheej txheem tom qab txheej qis tshaj plaws raug tamped down, tom qab ntawd ncuav aerated pob zeb rau ntawm txheej txheem, thiab tom qab ntawd tso ib txheej asbestos rwb thaiv tsev, thiab tom qab ntawd tso ib txheej dej tsis muaj dej thiab daim ntaub tsis-woven rau ntawm txheej sab saud.
Kev sib ntsib zoo li no ua rau daim ntaub raug nthuav tawm, hauv qab lub teeb ci ntsa iab ntev ntawm ultraviolet, ua rau nws lub neej luv dua; Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, tib neeg pheej tsim kho tshiab, tsim cov qauv rwb thaiv tsev tshiab: txoj kev ntawm kev hloov pauv rwb thaiv tsev, txoj kev no yog thiab txoj kev ib txwm muaj, ua rau sab saum toj ntawm cov txheej tsis muaj dej thiab geotextile tso rau hauv cov txheej rwb thaiv tsev asbestos ua npuas ncauj hauv qab, ua rau daim ntaub tsis raug nthuav tawm tob hauv av, yog li ua rau lub neej kev pabcuam ntev dua thiab ua rau lub cev tseem ceeb ntawm rwb thaiv tsev ruaj khov dua, txhim khu kev qha, thiab txuag tus nqi ntawm cov nqi engineering.
