Qhov tseem ceeb Waterproofing Solutions & Qhov txawv tseem ceeb hauv Cov Qauv Ntiaj Teb
Dej tsaws tsagyog ib qho tseem ceeb ntawm cov dej tsis zoo uas tsim los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam, nws yog qhov tsim nyog yuav tsum tau ua tib zoo saib xyuas. Siv rau hauv kev tsim cov pob qij txha, cov pob qij txha nthuav dav, thiab cov pob qij txha sib txuas, lawv tau tsim los ntawm cov khoom siv xws li roj hmab (natural, EPDM, neoprene), thermoplastics (PVC, HDPE, EVA), lossis hlau (steel, tooj liab) kom hloov mus rau ntau yam ib puag ncig thiab cov kev xav tau ntawm qhov project. Los ntawm tunnels thiab dams mus rau hauv qab daus thiab cov kav dej phwj tuaj, cov dej tso dej ua lub luag haujlwm tseem ceeb hauv kev tsim kho thoob ntiaj teb- nrog rau kev ua tau zoo raws li cov qauv hauv cheeb tsam thiab thoob ntiaj teb uas sib txawv hauv kev tsom, kev sim, thiab daim ntawv thov.
i. Core Hom Waterstops
Roj hmabDej tsaws tsag: Muab siab elasticity thiab yooj, zoo tagnrho rau dynamic pob qij txha nrog txav.
ThermoplasticDej tsaws tsag: Weldable, corrosion{0}}tiv taus, thiab tus nqi- zoo rau cov haujlwm loj -.
HlauDej tsaws tsag:Muab rigidity rau cov dej siab, feem ntau coated rau kev txhim kho pob zeb sib txuas.
CompositeDej tsaws tsag: Muab cov polymers nrog cov tshuaj hydrophilic lossis steel strips rau kev sib khi dual.
II, Cov Qauv Tseem Ceeb Ntiaj Teb & Lawv Qhov Sib Txawv
1. ISO Standards (International)
TS EN ISO 10933 Cov txheej txheem tseem ceeb thoob ntiaj teb rau thermoplasticntug dej, qhia cov kev xav tau rau lub zog tensile, weld peev xwm, thiab tshuaj lom neeg tsis kam. Nws hais txog kev sib raug zoo thoob ntiaj teb, nrog cov cim tseem ceeb xws li Ntau dua lossis sib npaug ntawm 16 MPa lub zog tensile thiab Ntau dua lossis sib npaug rau 600% elongation ntawm kev tawg rau HDPE / EVA variants. ISO cov qauv yog kev yeem, tab sis dav siv nyob rau hauv cross- tej yaam num ciam teb, tsom rau kev ua tau zoo thoob ntiaj teb cov qauv es tsis yog lub cheeb tsam tshwj xeeb.
2. ASTM Standards (USA)
ASTM cov qauv (piv txwv li, ASTM D638 rau plastics, ASTM D412 rau roj hmab) yog kev yeem, kev qhia ntxaws ntxaws, thiab ua kom muaj kev ua haujlwm tseem ceeb. Lawv txhais cov txheej txheem xeem kom meej-piv txwv li, siv cov dumbbell tshwj xeeb- cov qauv zoo li rau kev ntsuas tensile- nrog rau kev tsom mus rau cov khoom sib xws. Tsis zoo li ISO, ASTM tso cai rau kev hloov pauv ntau dua hauv cov khoom tsim thaum ua kom zoo, ua rau nws mus - rau North American cov haujlwm.
3. DIN EN Standards (Tebchaws Europe)
DIN EN 14891, sib haum xeeb nrog ISO, ntxiv nruj dua - qhov kub thiab txias (-50 degree) rau thaj tsam Nordic thiab txias. Nws kuj ua raws li EU CE cim cov cai, hais txog kev ua haujlwm ntev hauv huab cua hnyav thiab tshuaj lom neeg tsis kam rau kev lag luam. DIN cov qauv (xws li DIN 18541) tswj cov polymericntug dejqhov ntev thiab cov khoom siv hauv kev nthuav dav.
4. JIS Standards (Nyiv)
JIS K6385 tsom rau roj hmabntug dej, nrog rau qhov tseem ceeb ntawm ozone tsis kam thiab kev co nqus. Nws yuav tsum tau ua kom nruj dynamic ozone aging kev ntsuam xyuas thiab qhia txog tus qauv ntsuas kub ntawm 23 ± 2℃(27 ± 2℃rau cov cheeb tsam kub). JIS cov qauv yog tsim raws li Nyiv cov kev xav tau kev nyab xeeb thiab kev tsim kho vaj tse, ua ntej lub sijhawm ntev - kev ua tau zoo hauv thaj chaw seismic.
5. GB Standards (Tuam Tshoj)
GB/T 18173.2-2014 hais txog ISO tab sis suav nrog kev hloov kho hauv zos. Qhov sib txawv tseem ceeb suav nrog qhov ntsuas qhov ntsuas kub qis dua (-70℃rau RT vs ISO's -40 degree), kev cai dumbbell cov qauv rau kev ntsuas tensile, thiab siab dua ozone concentration. Nws kuj ntxiv cov kev txwv rau cov dej tsis sib xyaw, xws li lub zog shear nrog cov pob zeb, hais txog cov kev xav tau tshwj xeeb ntawm Suav infrastructure.

IV. Xaiv Tus Qauv Zoo
Xaiv tus qauv nyob ntawm qhov project qhov chaw, ib puag ncig, thiab kev tswj hwm xav tau. ISO yog qhov zoo tagnrho rau cov haujlwm thoob ntiaj teb, thaum ASTM haum rau North America, DIN EN rau Europe, JIS rau Nyiv, thiab GB rau Tuam Tshoj. Rau cov xwm txheej huab cua- huab cua txias (DIN EN), thaj chaw seismic (JIS), lossis dej siab (GB)- cov qauv hauv cheeb tsam muab kev lees paub ua haujlwm zoo.
