Moqolo rulela. Menyetla, go tlhoka mesola, mefuta e ka sehloohong ea

Moqolo rulela thepa ba ho pharaletseng sebelisoa ka sethusathuto ea marulelong. Marulelong ea tsena ke se seng sa tse ngata theko e tlaase le e bonolo ka thekenoloji ho etsa thepa. Ho sa tsotellehe cheapness mong ka bona, ha tsohle theknoloji e mene-lera barbotage ea lintho tse bonahalang ho rulela tla tšoana le ho, 'me tsa tšepe marulelong a galvanized tšepe. Leha ho le joalo, marulelo a lintho tse bonahalang ho rulela ke e 'ngoe bohlokoa drawback - haholo chang.

thepa bonolo ho rulela stacked le dikarolo tse 'maloa, e mong le e ba tse nkang mosebetsi itseng. Backsheet ke uncoated lintho tse bonahalang (lera), 'me ka holimo - coverslips. The tšobotsi e ka sehloohong ea ho koahela lintho tse bonahalang - ke ho ba teng ha lera nang posypku (leru la lerole-joaloka, o motle-grained kapa mahoashe-grained) le refractory sekontiri.

Ka ho fetisisa e atisa ho sebelisoa moqolo rulela - e sekontiri, ho rulela o ile a ikutloa le lintho tse bonahalang ho rulela. Ba bonolo haholo ho amoheloa ke lithaka. Ba sebelisoa ka marulelong ka letsoapong hanyenyane ka mong sengoathoana botlaaseng.

E mong oa thepa e khōlō ea thepa le bonolo ho rulela - metsi manganga. thepa ena e hlokomelwa feela ka botšepehi ba tletse lintho tse bonahalang tse, i.e. ho ba sieo ha meokho le mapetsong.

Marulelong ho fumana boleng, tsoarellang, thepa moqolo ho rulela lokela ho ea kopana le dihlahlobo tse latelang:

• Roba matla (lintho tse bonahalang e tsekolotsoeng ka hlobolisa ea cm, 5, 'me boiteko bo eketsehileng ka tsela eo e sebelisoa, le matla le ho feta lintho tse bonahalang tse);
• lintho tse bonahalang ho hanyetsa mocheso;
• tenyetsehe ya lintho tse bonahalang tse o ile a hlahlojoa ke mocheso se tlaase-tlaase ho boo ho seng mapetsong ka koba ea molamu.

Rulela. mefuta

Ho itšetlehile ka substrate ea, thepa moqolo ho rulela Ho na le mefuta e latelang:

• ka sebopeho sa seile - tsa motheo le se nang motheo;
• dikarolo mofuta oa ea ho hlophisoa barbotage - polymer, sekontiri se thata, sekontiri-polymer;
• ke metheo mofuta - lebokoso, asbestos, fiberglass, polasetiki le likarolo tse ngata;
• ka sebopeho sa lera le sireletsang - ka foil kapa filimi, e flake, pulverized, mahoashe, o motle-grained.

Hape, ho itšetlehile ka binders, ba ile ba ba polymer-sekontiri se thata kapa sekontiri.

Bituminous rulela na ditefello tlaase le boleng tlaase bakeng sa sravneniiyu le polymer-sekontiri se thata. The bozangi litomba ke tlaase serame ho hanyetsa. Leha ho le joalo, boitsebiso boo e atisa ho sebelisoa bakeng sa sebopeho sa ka hare tsa metsi ho e loketseng ho hanyetsa mongobo.

Polymer-sekontiri se thata ho rulela moqolo thepa na melemo e bo boholo ho feta ba pele. Leha ho le joalo, theko ea bona e phahameng. Ba na le lengolo la phahameng tsa durability le tšepahala, manganga ho thempereichara e phahameng haholo le tlaase. Litšobotsi tsena lia makhaola-khang ka tlhopho ya thepa rulela ho khahlapetsa maemo a klimate ba naha ya rona. thepa tsena ka nka nako e ka etsang 25 lilemo tse, ho thekenoloji tlhahiso le rala marulelong.

Le mefuta e fapaneng e lekaneng ea ho rulela tse bonahalang sekontiri-polymer moqolo ke lentsoe le le lecha ka morao-rao e marulelong sekoahelo. Leha ho le joalo, ha u khetha o lokela ho ba le lintho tse tlang pele le ho etsa qeto ea seo ke sa bohlokoa ho feta: theko kapa boleng?
