Lub hnab yas woven yog ua los ntawm polypropylene (PP) yog cov khoom siv tseem ceeb, uas yog extruded, kos, thiab tom qab ntawd cov ntaub ntawv, ntaub plaub, thiab ua rau hauv hnab. PP yog lub pob tshab, semi-crystalline thermoplastic. Nws muaj cov yam ntxwv ntawm lub siab muaj zog, zoo rwb thaiv tsev, tsis tshua muaj dej nqus, siab kub ua kom muaj cua sov, tsis ntom ntom, thiab siab ci. Nws yog cov khoom siv tseem ceeb rau kev ua lub hnab ua ntaub. Hloov kho cov ntsaws feem ntau suav nrog cov iav ua kom muaj zog, cov ntxhia ntxig rau, thiab cov ntawv pleev cov roj thermoplastic. Cov ntaub qhwv lub hnab yas yog siv dav. Tam sim no, cov hnab yas woven yog siv dav rau cov khoom siv ua liaj ua teb ntim, ntim hnab ntim cov hnab ntim khoom noj, ntim khoom noj khoom haus, geotechnical engineering, kev thauj mus los, kev tswj dej nyab, thiab lwm yam. woven hnab thiab ntau yam ntaub xov paj. Cov txheej txheem ntau lawm ntawm cov hnab yas woven yog: daim ntaub qhwv los ua luam ntawv, txiav, thiab xaws los ua cov hnab ntim khoom.
Nyob ntawm cov cuab yeej siv, nws tuaj yeem txiav ua ntej thiab tom qab ntawd luam tawm, lossis luam ntawv ua ntej thiab tom qab ntawd txiav. Tsis siv neeg txiav thiab xaws tau txuas ntxiv ua tiav luam ntawv, txiav, xaws thiab lwm yam txheej txheem, thiab tuaj yeem ua rau lub hnab valve, hnab hauv qab, thiab lwm yam, rau cov ntaub qhwv tsis tiaj, lub hnab tuaj yeem tsim los ntawm kev sib khi. Cov txheej txheem ntau txheej txheem ntawm cov ntawv ntim hnab yas yog kom sib xyaw lossis tsho tiv thaiv cov ntaub, cov khoom siv txheej thiab ntawv lossis zaj duab xis. Daim ntaub qhwv lub raj los yog ib daim ntawm cov ntaub tuaj yeem txiav, luam tawm, stitched, thiab ua rau cov hnab ntim uas tsis xws leej twg hauv qab, lossis nws tuaj yeem xuas nrig ntaus, khawm, txiav, luam tawm, thiab stitched los ua cov hnab cement. Tau txais ntawm daim ntaub, Muaj peev xwm muab lo rau hauv nruab nrab seam, luam tawm, txiav, muab tshuaj txhuam hauv qab, ua cov hnab ntim rau hauv qab. Nws kuj tuaj yeem tau txais welded, dov, thiab ua rau hauv tarpaulin thiab geotextile. Cov ntaub npuag dav tuaj yeem raug coated lossis tsis siv los tsim cov tshuab tarpaulin, geotextile, thiab lwm yam. Cov ntaub ntuag los kuj tseem tuaj yeem ua kom ntom lossis tsis xeb los tsim tarpaulin lossis geotextile, thiab lwm yam.
