Chinese 3PE anticorrosive zitsulo chitoliro wopanga
1. Kuchepetsa mtengo wa ntchito
Malinga ndi mawerengedwe a m'madipatimenti zogwirizana, zambiri, polyurethane insulated zitsulo chitoliro akhoza kuchepetsa ntchito mtengo ndi pafupifupi 25% (pogwiritsa ntchito FRP monga wosanjikiza zoteteza) ndi 10% (pogwiritsa ntchito polyethylene mkulu-osalimba ngati wosanjikiza zoteteza).
2. Kutaya kutentha kochepa komanso kupulumutsa mphamvu
Kutentha kwa matenthedwe a polyurethane ndi: λ= 0.013-0.03kcal/m · h · OC, yomwe ndi yotsika kwambiri kuposa zida zina zotchinjiriza mapaipi m'mbuyomu, ndipo mphamvu yotchinjiriza imasinthidwa nthawi 4 ~ 9. Komanso, mayamwidwe ake ndi otsika kwambiri, pafupifupi 0.2kg/m2. Chifukwa cha kuyamwa kwamadzi otsika ndikuti thovu la polyurethane lili ndi porosity yotsekedwa pafupifupi 92%. Low matenthedwe madutsidwe ndi otsika mayamwidwe madzi, pamodzi ndi matenthedwe kutchinjiriza wosanjikiza ndi mkulu-kachulukidwe polyethylene kapena FRP zoteteza chipolopolo ndi ntchito yabwino madzi kunja, asintha zinthu "kuvala chonyowa thonje padded jekete" ya ngalande miyambo atagona payipi kutentha kotunga, ndipo kwambiri. inachepetsa kutayika kwa kutentha kwapaipi yoperekera kutentha. Kutayika kwa kutentha kwa netiweki ya kutentha ndi 2%, yomwe ndi yocheperapo kuposa zomwe zimafunikira padziko lonse lapansi za 10%.
3. Anti dzimbiri, kutchinjiriza bwino ndi moyo wautali utumiki
Chifukwa polyurethane okhwima thovu kutchinjiriza wosanjikiza zomangika mwamphamvu ku khungu lakunja chitoliro zitsulo, kulowetsedwa kwa mpweya ndi madzi akhoza kudzipatula, ndi zotsatira zabwino anticorrosion chingapezeke. Nthawi yomweyo, ma pores ake otulutsa thovu amatsekedwa ndipo kuyamwa kwake kumakhala kochepa kwambiri. Chipolopolo cha polyethylene chapamwamba kwambiri ndi chipolopolo cha FRP chimakhala ndi anti-corrosion, kutchinjiriza komanso makina. Choncho, khungu lakunja la ntchito zitsulo chitoliro n'zovuta kuti kukokoloka ndi kunja mpweya ndi madzi. Malingana ngati madzi amkati a payipi akusamalidwa bwino, malinga ndi deta yakunja, moyo wautumiki ukhoza kufika zaka zoposa 50, zomwe ndi 3 ~ 4 nthawi yaitali kuposa momwe zimakhalira ngalande ndi kuyala pamwamba.
Poyerekeza ndi chikhalidwe zitsulo chitoliro kutchinjiriza njira, ndi prefabricated mwachindunji kukwiriridwa kutchinjiriza zitsulo chitoliro ali ndi ubwino wotchuka kwambiri:
1.The prefabricated mwachindunji anakwiriridwa insulated zitsulo chitoliro safuna kumanga ngalande yaikulu, koma ayenera kukwiriridwa insulated chitoliro mobisa, amene amachepetsa kwambiri dziko ntchito ya polojekiti, ndi yabwino kuteteza chilengedwe, amachepetsa kuchuluka kwa pofukula earthwork ndi zambiri. kuposa 50%, ndipo amachepetsa kuchuluka kwa zomangamanga ndi konkire ndi 90%. Panthawi imodzimodziyo, kumangidwe kwa chitoliro chosungunula kumachitika mofanana ndi malo otsetsereka, ndipo malo okhawo amafunikira, omwe angafupikitse nthawi yomangayo ndi 50%.
2.Ntchito yosungira kutentha ndi yabwino, ndipo kutaya kwa kutentha ndi 25% yokha ya mapaipi achikhalidwe. Kugwira ntchito kwa nthawi yayitali kumatha kupulumutsa mphamvu zambiri ndikuchepetsa kwambiri mtengo wamagetsi.
3.Ili ndi mphamvu yoletsa madzi komanso kukana dzimbiri. Sichiyenera kumangirira ngalande ya chitoliro. Ikhoza kukwiriridwa mwachindunji pansi kapena m'madzi. Ntchito yomangayi ndi yosavuta komanso yofulumira, ndipo mtengo wake ndi wotsika.
4. Ilinso ndi kukana bwino kwa dzimbiri komanso kukana kukhudzidwa ndi kutentha kochepa, ndipo imatha kukwiriridwa mwachindunji munthaka yachisanu yapansi panthaka.
5.Moyo wautumiki ukhoza kufika zaka 30-50. Kuyika bwino ndi kugwiritsa ntchito kungapangitse mtengo wokonza ma netiweki wa chitoliro ukhale wotsika kwambiri.
6. Dongosolo la alamu litha kukhazikitsidwa kuti lizidziwikiratu vuto la kutayikira kwa netiweki ya chitoliro, kuwonetsa molondola malo olakwika ndi alamu yokha.
