Sab hauv Butyl Rubber Waterproofing
Thaum dej pom qhov tsis muaj zog hauv lub tsev, cov txiaj ntsig feem ntau yog kim thiab cuam tshuam. Tias yog vim li cas specifiers tig mus rau butyl roj hmab. Raws li ib tug hluavtaws elastomer, butyl muaj lub cev zoo uas ua rau nws yuav luag khawv koob nyob rau hauv lub ntiaj teb no tsim: ib tug tsis tshua muaj permeability rau gases thiab dej vapor. Txawm tias thaum stretched los yog compressed ntau xyoo ntawm qhov kub thiab txias viav vias, nws tsis kam cia ya raws hla.
Vim tias qhov tawv tawv tsis kam tiv thaiv cov ntsiab lus, butyl roj hmab waterproofing membranes tau dhau los ua - los tiv thaiv hauv cov txheej txheem tseem ceeb. Koj yuav pom cov ntaub ntawv no nyob rau hauv lub ru tsev ntawm loj loj warehouses, qhwv nyob ib ncig ntawm lub hauv paus ntawm underground chaw nres tsheb lug, thiab sealing lub sab hauv ntawm railways thiab txoj kev loj tunnels. Nyob rau hauv qhov, piv txwv li, daim nyias nyias ua raws li ib tug impermeable kaus, tiv thaiv loj heev hydrostatic siab los ntawm ib puag ncig lub ntiaj teb. Tshaj li kev tsim kho hnyav, qhov sib txawv ntawm cov nplooj ntawv no hnyav heev siv rau hauv lub suab nrov ntawm lub tsheb thiab txawm tias lub tsev sib dhos ua ke.
Raws li kev lag luam uas yuav tsum tau ua, cov khoom yuav luag ib txwm tso siab rau cov txheej txheem txheej txheej thiab lamination.
Cov txheej txheem txheej txheem suav nrog kub - yaj lossis cov kuab tshuaj tshwj xeeb- raws li txheej txheej. Cov txheej txheem feem ntau pib nrog yob ntawm daim ntawv tso tawm ua tus neeg nqa khoom ib ntus. Cov khoom siv raw butyl- uas feem ntau suav nrog cov tackifying resins thiab muab tso rau los kho nws qhov nyuaj kawg nkaus - yog ua tib zoo rhuab thiab ntsuas rau hauv daim ntawv no. Vim hais tias butyl yog viscous thiab elastic, yooj yim kis nws tusyees yog qhov nyuaj; lub taub hau txheej xav tau kev tswj xyuas qhov sib txawv kom ntaus qhov hnyav tshwj xeeb, feem ntau yog li ntawm 1 txog 2 millimeters hauv qhov kawg tuab.
Tam sim ntawd tom qab siv cov butyl, ib qho khoom siv thib ob- xws li lub siab - ntom polyethylene (HDPE) zaj duab xis, aluminium ntawv ci, los yog cov ntaub ntawv reinforced - yog laminated rau saum. Cov txheej saum toj no muab cov membrane nws lub zog txhua yam kom muaj sia nyob ntawm kev tuav ntawm qhov chaw tsim kho. Cov khoom sib xyaw ces dhau los ntawm qhov ua kom txias txias. Cov kauj ruam no tseem ceeb heev; Yog hais tias lub butyl tsis txias uniformly, nws tuaj yeem deform lossis lo rau lub tshuab chais, ua rau cov kab nres loj heev.
Raws li cov chaw tsim khoom ntawm kev cai txheej thiab cov khoom siv laminating, peb nkag siab txog kev mob taub hau ntawm kev ua haujlwm nrog butyl. Nws yog ib qho khoom siv uas xav tau kev tswj xyuas qhov tsis zoo thermal thiab kev tswj nruj nruj thoob plaws qhov tsis muaj zog thiab rov qab. Peb cov tshuab tau tsim tshwj xeeb los tswj cov qib siab no -tack, hnyav- cov haujlwm ua haujlwm, kom ntseeg tau tias cov chaw tsim khoom tuaj yeem tsim cov ntaub ntawv tiv thaiv dej tsis tu ncua uas tsis tas yuav muaj kev hem thawj ntawm cov khoom tsim lossis kev sib raug zoo.
Raws li kev lag luam uas yuav tsum tau ua, cov khoom yuav luag ib txwm tso siab rau cov txheej txheem txheej txheej thiab lamination.
Cov txheej txheem txheej txheem suav nrog kub - yaj lossis cov kuab tshuaj tshwj xeeb- raws li txheej txheej.
