Dej- nthuav dav cov kab sib xyaw: siv cov qauv thiab cov txheej txheem tshwj xeeb, nrog rau qhov chaw du, huab cua zoo, kev nqus dej sai thiab nthuav dav, rov nqus dej tsis ua haujlwm, thiab tsis muaj qhov loj me me tom qab ua tiav cov dej poob thiab ziab, ua rau koj nyob mus ib txhis kev thaj yeeb nyab xeeb ntawm cua thiab los nag, thiab tsuas yog kev xaiv rau siab - qhov rooj thiab qhov rais kaw.
Dej-swellable composite strips yog tsim los ntawm combining dej-swellable roj hmab thiab EPDM roj hmab. Ib los yog ntau dua dej- cov strips swellable yog co-extruded ntawm qhov chaw xaiv ntawm cov pa EPDM strips. Cov strips no feem ntau yog siv rau sab nrauv iav sealing. Yog hais tias sab nrauv ntawm lub qhov rooj thiab qhov rais tsis ua haujlwm thiab cov dej nag me me nkag rau hauv, cov strips nqus dej thiab nthuav dav, ua tiav cov dej tsis sib haum.
FAQs rau dej- swelling Composite Sawb
1. Q: Dej yog dab tsi - swelling Composite Sawb thiab nws ua haujlwm li cas?
A:A Dej- o Cov Kab Ntsig yog cov khoom sib khi zoo tshaj plaws uas tsim los ua kom muaj zog, tus kheej - sealing tiv thaiv dej hauv qab hydrostatic siab. Nws yog "composite" vim tias nws feem ntau ua ke cov roj hmab ruaj khov, hloov tau yooj yim (xws li EPDM lossis Neoprene) nrog cov tub ntxhais lossis txheej ntawm super-absorbent polymer. Thaum raug dej, txheej txheej polymer absorbs dej thiab swells volumetricically, ntau zaus nws qhov loj me. Qhov kev tswj xyuas kev nthuav dav no ua rau muaj qhov loj, tsis tu ncua ntawm qhov chaw nyob ib puag ncig, tuaj yeem sau cov voids, tawg, thiab qhov tsis sib xws los tsim ib qho zoo meej,Watertight foobnyob rau hauv cov qauv uas passive gaskets tsis txaus.
2. Q: Qhov twg yog cov dej- o Cov Kab Tsuag Sib Tsoo feem ntau siv?
A:Cov strips no tseem ceeb heev hauv cov ntawv thov uas tiv thaiv dej nkag yog qhov kev sib tw loj hauv engineering. Lawv cov kev siv tseem ceeb suav nrog:
Kev tsim kho hauv av:Sealing kev tsim kho pob qij txha hauvtunnels, subways, thiab underground hauv qab daus.
Waterproofing Joints:Kev sib khiexpansion pob qij txha thiab txav pob qij txhanyob rau hauv cov vaj tse pob zeb zoo li cov nroj tsuag kho dej, reservoirs, thiab pas dej da.
Pipe Penetrations:Sealing nyob ib ncig ntawm cov yeeb nkab thiab cable nkag los ntawm cov phab ntsa pob zeb thiab slabs.
Ua ntej- ntu ntu:Siv los ua gaskets nruab nrab ntawm ntu hauv ua ntej -cast concrete tunnel boring machine (TBM) tej yaam num, qhov uas lawv yog thawj tiv thaiv dej hauv av.
3. Q: Kuv yuav ua li cas rau nruab ib lub qhov dej - swelling Composite Sawb?
A:Kev txhim kho yog qhov tseem ceeb rau kev ua haujlwm. Cov txheej txheem dav dav yog:
Kev npaj nto:Lub pob zeb lossis substrate nto yuav tsum huv si, suab, tiaj tus, thiab tsis muaj plua plav, roj, lossis laitance kom ntseeg tau tias muaj kev nplaum siab tshaj plaws.
Daim ntawv thov Adhesive:Kev ua haujlwm siab -kev ua tau zoo, dej- resistant structural adhesive yog siv rau lub sawb tsis yog - sab o.
Qhov chaw ruaj khov:Lub strip yog ces nrees nias rau ntawm qhov chaw npaj, kom ntseeg tau tias tag nrho kev sib cuag tsis stretching. Nws yog feem ntau mechanically tsau ntawm ib ntus rau kev ruaj ntseg ua ntej lub pob zeb ncuav los yog vaj huam sib luag tso.
Kho:Cov nplaum yuav tsum tau tso cai kho kom zoo raws li cov chaw tsim khoom cov lus qhia ua ntej qhov sib koom ua ke raug kaw thiab raug rau cov dej sib cuag.
4. Q: Lub peev xwm o yog dab tsi thiab nws siv sijhawm ntev npaum li cas los qhib?
A:Qhov kev ua tau zoo yog ntsuas los ntawm nws qhov o muaj peev xwm thiab tus nqi. High- cov strips zoo tuaj yeem ua tiav ibo muaj peev xwmntawm 200% mus rau 500% ntawm lawv thawj ntim. Covtus nqi otsis yog instantaneous; nws feem ntau pib nyob rau hauv feeb ntawm kev sib cuag tab sis tuaj yeem siv sijhawm li ob peb teev mus rau ob peb hnub kom ncav cuag nws qhov siab tshaj plaws, nyob ntawm qhov tshwj xeeb polymer formulation thiab dej. Qhov kev tswj xyuas no tso cai rau nws ua haujlwm zoo tiv thaiv ob qho tib si qeeb seepage thiab dej siab dua.
5. Q: Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm txoj kev sib khi ib txwm muaj xws li waterstops lossis bentonite?
A:Dej- swelling composite strips muaj ntau yam zoo:**
Active Sealing:Tsis zoo li passive PVC waterstops, nws nquag nthuav mus kaw qhov khoob, them nyiaj rau me me los yog kev tsim kho tsis zoo.
Superior rau Bentonite:Nws muab ntau txhim khu kev qha thiab zoo ib yam o siab dua bentonite strips, uas yuav ua tau nquag ntxuav tawm los yog muaj "qhov chaw tuag." Cov qauv tsim muaj kev sib xyaw ua ke zoo dua qub thiab adhesion.
Tus kheej -Khoom Zoo:Nws tuaj yeem rov qab - o yog tias qhov me me tshwm sim los yog qhov tawg me me tshiab tsim, muab kev tiv thaiv ntev -.
Durability:Cov roj hmab thim rov qab muab kev tiv thaiv lub cev muaj zog thaum lub sijhawm teeb tsa thiab kev pabcuam, tsis zoo li cov av nplaum yooj yim dua - raws li cov khoom lag luam.
