Rau ntau tshaj 40 xyoo, EPDM daim nyias nyias tau nyob ib qho chaw tseem ceeb hauv kev lag luam khoom siv hauv tsev. Qhov no yog cov khoom siv waterproofing uas tau siv dav los ntawm cov neeg yuav khoom. Peb tuaj yeem hais tias nws tau sawv qhov kev sim ntawm lub sijhawm.
EPDM daim nyias nyias. Qhov no yog dab tsi?
Nws yog ib qho dej tsis zoo uas yog tsim los ntawm cov roj hmab. Nws muaj ethylene-propylene-diene monomer. Txhawm rau kom muaj zog, ntxiv dag zog nrog polyester mesh yog nqa tawm. Qhov no ua rau nws siv tau cov khoom siv hauv txhua cheeb tsam, txawm tias muaj huab cua txias.
EPDM daim nyias nyias ua los ntawm cov ntaub ntawv sib xyaw yog ib pawg cais. Hauv qhov no, lawv muaj peb txheej:
- dense rubber;
- xov mesh;
- Ypolymer bitumen.
EPDM membrane yam ntxwv thiab qhov zoo
EPDM Membrane yog cov yeeb yaj kiab zoo vulcanized uas yog tsim los ntawm ib hom EPDM roj hmab. Cov ntaub ntawv nyoos raug tswj xyuas nruj kom ua raws li cov qauv European.
Cov ntaub ntawv zoo,tej yam additives, niaj hnub tsim technologies - tag nrho cov no yog ib tug EPDM membrane. Nws cov yam ntxwv muab nws ntau qhov zoo dua lwm cov ntaub ntawv:
- nqi qis;
- zog;
- kev laus ua haujlwm, ua haujlwm ntev (kev pabcuam lub neej yog ib nrab xyoo);
- tiv thaiv qhov kub thiab txias;
- muaj huab cua, UV thiab ozone;
- khaws cia zoo thaum raug tshav ntuj ncaj qha mus ntev.
- hluav taws kub;
- khaws elasticity tshaj qhov kub ntau (los ntawm rho tawm 40 txog ntxiv rau 110 degrees);
- muaj qhov hnyav;
- tsis hnov mob nrog cov ntaub ntawv bituminous;
- stretch ratio ncav cuag 400% nrog tag nrho rov qab tom qab;
- cov khoom siv hauv ib puag ncig, tsis tso cov tshuaj lom mus thoob plaws lub neej ua haujlwm;
- tuaj yeem siv rau ntau hom ru tsev;
- qhov loj ntawm daim nyias nyias tau hloov kho rau qhov loj ntawm lub ru tsev, rau qhov no ob peb yob txuas nrog vulcanization (cov seams muaj cov khoom siv hauv paus, qhov loj ntawm ib daim ntawv tuaj yeem ncav cuag 1200 m2);
- ru tsev ua dej tsis zoo thiab nyob twj ywm;
- Tsis tas yuav nteg geotextile ntawm EPDM daim nyias nyias thiab txheej txheej thermal rwb thaiv tsev.
Kev tsis haum ntawm daim nyias nyias
Ntxiv rau ntau qhov zoo, EPDM daim nyias nyias kuj muaj qhov tsis zoo. Qhov tseem ceeb tshaj plaws ntawm lawv yog lub installation yog nqa tawm siv kua nplaum. Lub resulting sib txuas seam txo lub zogkhoom.
Tsis muaj lwm yam teeb meem loj hauv cov khoom.
Type thiab manufacturers ntawm EPDM membrane
Nyob hauv kev lag luam khoom siv hauv tsev, muaj ntau hom EPDM membranes los ntawm ntau lub tuam txhab. Tag nrho cov ntawm lawv txawv ntawm ib leeg nyob rau hauv lawv cov yam ntxwv (nqi, zoo). Cov tseem ceeb yog:
1. hluav taws kub. Xws li ib txheej tab sis ntxiv dag zog thiab nplaim retardant. Cov muaj pes tsawg leeg muaj xws li EPDM, carbon dub, technical oil thiab additives, vulcanizing agents. Cov yob yog 15m dav thiab tuaj yeem ntev txog 61m.
Lub Firestone EPDM membrane muaj ntau qhov zoo:
- ozone thiab UV tiv taus;
- muaj hnav tsis kam;
- tseem hloov pauv txawm tias nyob hauv huab cua hnyav heev (kuj mus txog 6 degrees);
- muaj qhov kub thiab txias;
- ib puag ncig phooj ywg;
- Yuav ua tau kom ntev cov khoom.
2. Giscolene. Qhov no yog ib txheej vulcanized khoom, uas muaj xws li propylene, diene thiab ethylene. Nws yog tsim nrog qhov dav ntawm 1.5-20 m, thaum lub thickness ntawm cov khoom tsuas yog 0.5-4 hli. Siv rau txhua hom ru tsev vim nws qhov zoo:
- impervious rau dej thiab huab cua;
- khoom siv suab nrov;
- Resistant rau tshav kub, hnav, kub heev thiab tshuaj.
3. "Elastokrov". Ib yam khoom tshiab, zoo ib yam hauv nws cov yam ntxwv rau Firestone membrane. Khoom thickness - 1,4 mm. Dav -3-4, 5 m. Ntev - 50 meters.
4. "Carlisle". Rolls ntawm cov khoom no muaj qhov ntev ntawm 30.5-61 m. Qhov dav yog 6.1-18.3 meters, thiab lub thickness yog 1.5-2.3 hli. Daim nyias nyias EPDM "Carlisle" yog tsim los ntawm hluavtaws fiber ntau thiab txawv ntawm lwm hom hauv nws cov yam ntxwv. Qhov txawv ntawm qhov tseeb tias nws tso cai rau cov kua nplaum tsis yog nrog cov kua nplaum nkaus xwb, tab sis kuj nrog kev siv mastic, sealant lossis daim kab xev nws tus kheej.
YSiv EPDM membrane
EPDM daim nyias nyias yog siv rau hauv qhov chaw uas koj xav tau sai, tab sis tib lub sijhawm ua kom muaj dej tsis zoo ntawm thaj chaw loj. Daim ntawv thov tseem ceeb yog ru tsev waterproofing. Tsis tas li ntawd, EPDM daim nyias nyias yog siv rau hauv cov qauv hauv av, qhov av, cov kwj dej, cov pas dej.
Feem ntau siv EPDM membrane rau lub pas dej. EPDM zaj duab xis muaj kev nyab xeeb tag nrho rau nws cov neeg nyob hauv. Thiab nws elasticity, lub zog thiab ib tug xov tooj ntawm lwm yam zoo ua rau hom khoom no indispensable. Yog li ntawd, EPDM lub pas dej membrane siv ntau zaus dua li lwm cov yeeb yaj kiab, tau txais txoj haujlwm ua thawj coj.
Txoj Kev Mounting
EPDM membrane yog mounted yooj yim heev. Tab sis tseem nws yog qhov zoo dua tig mus rau cov kws tshaj lij. Muaj peb txoj kev teeb tsa:
- Txoj kev kub-welded, uas yog feem ntau. Nrog rau txoj kev no, cov npoo yog welded nrog ib tug tshwj xeeb apparatus. Nyob rau hauv qhov chaw nyuaj-mus txog (cov ces kaum, cov yeeb nkab tawm, qhov), kev tuav vuam yog siv.
- Txoj kev ballast feem ntau yog siv rau lub ru tsev tiaj tus (qhov chaw nqesru tsev tsis tshaj 15 degrees), vim nws yog qhov kev lag luam tshaj plaws.
- Cov membrane yog nteg tawm ntawm lub ru tsev thiab fastened nyob ib ncig ntawm lub perimeter, raws li zoo raws li nyob rau hauv lub hlws ris ntawm lwm yam khoom. Txuas nrog lub ballast kom nws tsis txhob raug cua los ntawm cua. Rau qhov no, siv cov pob zeb crushed, pebbles, paving slabs, thiab lwm yam.
- Txoj kev siv tshuab tau pom zoo rau cov ru tsev geometrically complex. EPDM daim nyias nyias yog txuas nrog lub hauv paus ua los ntawm cov ntoo, cov pob zeb muaj zog los yog corrugated board siv cov nplaum tshwj xeeb. Ib tug ntug rail yog nteg tawm raws perimeter, uas muaj ib txheej ntawm sealant. Nrog rau qhov ntev ntawm 20 cm, telescopic fasteners raug ntsia. Yog hais tias lub ru tsev txoj kab nqes tshaj 10 degrees, siv ib tug ntxiv disk tuav.
Txoj kev kho Membrane
Qee zaum, nws yuav tsim nyog los kho cov txheej txheem. Nyob rau hauv cov xwm txheej zoo li no, cov kws tshaj lij pom zoo kom hloov cov dej tsis huv hauv qhov chaw puas. Thiab ntawm no txhua yam yuav nyob ntawm seb hom vov tsev "pie" thiab cov txheej txheem ntawm nws cov installation. Yog tias cov dej tsis sib haum tau hloov pauv, ces qhov no yuav tsum tau ua nyob rau hauv txhua qhov chaw uas muaj peev xwm tshem tawm cov khoom siv vov tsev.
Vim nws qhov kev ua tau zoo thiab tsis muaj qhov tsis zoo, EPDM daim nyias nyias yog qhov kev xaiv zoo tshaj plaws rau vov tsev. Tej zaum, dhau sijhawm, nws yuav dhau los ua cov khoom siv vov tsev tseem ceeb. Kev siv cov khoom siv dej tsis zoo no yuav ua kom muaj kev ua haujlwm zoo rau lub sijhawm ntev. Qhov no tau raug sim hauv kev xyaum los ntawm ntau tus neeg yuav khoom.
