EPDM lera: tobileng

Ka lilemo tse fetang 40 a le 'maraka oa thepa ea kaho e ne a hlaheletse EPDM lera. Sena se lintho tse bonahalang thibela metsi, e leng e ho pharaletseng jala har'a bareki. Re ka re ke nako e telele.

EPDM lera. ha e le eng?

Ke tsamaiso e thibela metsi, e leng e thehiloe rabara. Ho kenyelletsa ditokiseletso ethylene-propylene-diene monomer. Ho eketsa matla a etsoa e eketsehileng matlafatso letlooeng poliester. Sena se etsa hore ho ka khoneha ho sebelisa boitsebiso boo sebakeng leha e le efe, esita le ka ho a leholimo a batang.

A sehlopha se fapaneng tsa lera la EPDM ke la kaho le likarolo tse ngata. Tabeng ena, ba ile ba akarelletsa ho le dikarolo tse tharo:

• le letšo-letšo rabara;
• eketsa letlooeng;
• polymer sekontiri.

Litšobotsi tse EPDM lera le melemo ea eona

Lera EPDM - vulcanized boleng bo phahameng filimi eo e etsoa ka mofuta o itseng oa rabara EPDM. lihlahisoa tse tala angoa ke ho laola ka tieo ka hore a latele melao-motheo ea European.

thepa boleng e tala, tse itseng additives, theknoloji ea kajeno e fana ka tlhahiso - kaofela ha EPDM lera. Features hae e fa nomoro ea menyetla holim'a thepa e 'ngoe:

• theko e tlase;
• matla;
• botsofali hanyetsa, durability (bophelong ba mashome a mahlano);
• ho hanyetsa mocheso;
• mamella bosa, UV le ozone;
• ka ho phethahetseng a sireletsa, ho ba le nako e telele ka letsatsi le tobileng.
• mollo ho hanyetsa;
• E sala e tenyetsehang ka hare ho mefuta e mocheso mefuta e fapaneng (ho tloha ho ho tloswa 40 ho mmoho 110 likhato);
• tlaase boima;
• Ha ho itšoara ka thepa e bituminous;
• otlolle karo-karolelano fihla 400% ka hlaphoheloa ka ho feletseng nakong e tlang;
• tikoloho tse bonahalang botsoalle, ha ho emit dintho nang le chefo e ho pholletsa le potoloho ea bophelo;
• Ho ka sebelisoa ka marulelong a mefuta e sa tšoaneng;
• lera boholo ho amoheloa ke lithaka e le boholo ba marulelo, sena makhetlo a mangata ba amanang ka vulcanization (the seams ke thepa ea lintho tse bonahalang e le setsi, boholo ba lakane e mong a ka finyella 1200 limithara ^2);
• marulelong fetoha neleng le lulang a hloekileng;
• pakeng tsa lera le lera la EPDM kwahelang ha ho hlokahala hore ho rala geotextile.

go tlhoka mesola ya lera la

Ntle le a 'maloa a menyetla, EPDM boetse e na le go tlhoka mesola ea eona. Bohlokoa ka ho fetisisa ba bona ba ke e le hantle hore ho hlongoa e atlehe ho sebelisa e sekgomaretsi. Sephetho le e kopanetsoeng seam ho fokotsa matla a boitsebiso boo.

Leha e le efe tse ling bofokoli bo tebileng boo se nang lintho tse bonahalang.

Mefuta le baetsi ba EPDM lera

Ka 'maraka oa thepa ea ho haha ho na le mefuta e fapaneng ya lera la EPDM ho tloha baetsi' maloa. Ba fapana ho e mong le tse ling tse ka litšobotsi tse ea bona (theko, quality). Ba ka sehloohong ba:

1. Firestone. Ho akarelletsa ho mokato le 'ngoe, empa matlafatsoa le lelakabe retardant. E entsoeng ka EPDM, carbon ntšo, oli thulaganyo le additives, vulcanizing mahlahana. Rolls tse 15 limithara ka bophara le bolelele ba ka fihla limithara tse 61.

Firestone EPDM lera o sebelisa menyetla:

• manganga ho ozone le mahlaseli khanya;
• Ho na le e phahameng durability;
• o hlola ka ho tenyetseha esita le ka serame (ho fihlela ho tloswa likhato 6);
• mamella ho se tšoane leha e le mocheso;
• hloekisa;
• ho ka etsahala ho eketsa boitsebiso boo.

2.Giscolene. Sena ba se nang balekane-lera phekola tse bonahalang, entsoe ka propylene, ethylene le diene. Hatisa 1.5-20 limithara ka bophara, e tšoanang tse bonahalang botenya - 0.5-4 feela limilimithara. E e sebediswa ka mefuta eohle ea marulelo leboha ho melemo ea eona:

• Ha ho feta metsi le moea;
• utloahala kwahelang tse bonahalang ;
• tsitsitseng ho futhumatsa, apara, liphetoho mocheso le mahlahana a lik'hemik'hale.

3. "Elastokrov". A tse bonahalang batlang e le ncha, ka tsela e tšoanang le litšobotsi tse lona ho Firestone lera. Boitsebiso bo botenya - 1.4 limilimithara. Bophara -. 3-4.5 limithara Length - limithara tse 50.

4. "Carlisle". Rolls tsa boitsebiso boo ba na le bolelele ba 30,5-61 m. Bophara moo 6,1-18,3 limithara, 'me ka botenya ba 1.5-2.3 limilimithara. EPDM lera "Carlisle" e etsoa ka Portage maiketsetso le fapane le mefuta e meng e ke litšobotsi tse bona. phapang e fumanoa e le hantle hore lera e lumelloa ho khomarela hammoho e sa feela sekgomaretsi empa hape le ho sebelisa ha sealant mastic kapa theipi sekgomaretsi.

Ho sebelisoa ha lera la EPDM

EPDM e sebelisoa ka libaka tse moo o lokela ho ka potlako, empa ka nako e le nngwe hore ke qete boleng metsi ho ya libakeng tse khōlō. Kopo ya sehlooho - thibela metsi. Ho phaella moo, EPDM lera e sebelisoa ka sekhukhu dibopeho, lithanele, melatsoana, matamo.

Sebelisoa hangata bakeng sa ho EPDM pond. EPDM filimi e sireletsehileng ka ho feletseng bakeng baahi ba oona. Le fetoha le maemo a eona, matla a le melemo e meng ho etsa mofuta ona wa lintho tse bonahalang ke ba bohlokoa haholo. Ka hona EPDM pond e sebediswa haholo hangata ho feta lifilimi tse ling, ho hapa boetapele.

ntseng bo eketseha mekhoa

EPDM lera e hlomamisa feela ho lekana. Empa e ke molemo ho retelehela ho barutehi. Ho na le mekhoa e meraro ea tlhomamiso:

1. Teplosvarnoy mokhoa hore ke atileng ka ho fetisisa. Ka mokhoa ona, metshetshe a welded ke sesebediswa se khethehileng. Libakeng tse atameleha (likhutlong, le dipholo tsa lipeipi, masoba) sebedisa pukwanana tjheseletsa.
2. Tsitsisang mokhoa fetisisa e atisa ho sebelisoa bakeng sa marulelo a bataletseng (moo marulelo letsoapong ka tlase ho 15 likhato), jwalo ka e ngata litšenyehelo.
3. lera e beha ka holim'a teraka le mounted ka pherimitha, hammoho le mateano lintho tse ling. Ho Sireletseha le tsitsisang sekepe, e le hore a se ke a fumana akhotsoang-hang. Ho etsa sena, sebelisa lehlohlojane, majoe, paving matlapeng le joalo-joalo.
4. The mokhoa phetha molao buelloa bakeng sa marulelo a geometrically rarahaneng. EPDM lera o palame botlaaseng entsoe ka lehong, e hahiloeng ka konkreite kapa Together ke sebelisa sekgomaretsi khethehileng. Bohale pherimitha e beha lath, le nang le mokato tsa sealant. Ka dikgao ya 20 cm, a hlomamisa telescopic fasteners. Haeba marulelo tšekamelo angle likhato tse fetang tse 10, e sebediswa ekelletsa moo disk pane.

Mekhoa ho lera ho lokisa

Maemong a mang, u ka 'na lokela ho koahela lokisa. Maemong a joalo, litsebi nkhothaletsa ho feletseng nka sebaka sa metsi ho ka libakeng tse senyehileng. Mona tsohle li tla itšetleha ka mofuta oa ho rulela "phae" le mokhoa oa ho instola tse. Ha metsi ho e fetola e sa fella, ka nako eo sena se lokela ho etsoa libakeng tsohle moo ho ka etsahala ho tlosa lintho tse bonahalang ho rulela.

Thanks ho tshebetso e hlollang le ho ba sieo ha mefokolo, EPDM lera - ka khetho e moholo bakeng sa ho rulela. Mohlomong ka nako e tla ba e kgolo ho rulela lintho tse bonahalang. Tshebediso ya boitsebiso boo sa keneleng metsi le tla fana ka boleng bo phahameng la mosebetsi o phethile bakeng sa nako e telele ea nako. Ena e netefalitsoeng ka liketso, ka palo e kholo ea bareki.
