EN545: Chitetezo cha Kudzikundikira kwa Mapaipi a Chitsulo cha Ductile

M'moyo wamakono wa m'mizinda, ukhondo ndi zofunikira pa kuteteza chilengedwe cha madzi a m'mizinda ziyenera kuganiziridwa. Kuti dzimbiri lisadetse madzi a m'mapaipi komanso kuti mapaipi asawonongeke mkati, khoma lamkati la mapaipi liyenera kuphimbidwa ndi chophimba chamkati. Pansipa tifufuza mwatsatanetsatane za chitetezo chamkati cha mapaipi achitsulo opangidwa ndi ductile.

Mtundu wa Chitetezo cha Dzimbiri cha Mkati

Chipinda cha simenti chimayikidwa pogwiritsa ntchito njira yolumikizira ya centrifugal. Njirayi imapanga malo osalala, ofanana, imapereka mgwirizano wolimba ndi khoma la chitoliro, komanso imapewa kusweka. Chipinda choletsa dzimbiri chimagawidwa m'magulu atatu kutengera mtundu wa madzi omwe amanyamula:

Zophimba zoteteza dzimbiri (onani tebulo pansipa)

1. Mzere Wokhazikika
Kugwiritsa Ntchito: Koyenera kugwiritsa ntchito madzi ambiri osaphika komanso akumwa
Zipangizo Zopangira Mkati: Mkati mwa Simenti ya Portland
Simenti ya simenti ndi chophimba choteteza dzimbiri chomwe chimatulutsa zinthu zamchere zikakhudzana ndi madzi, zomwe zimapangitsa kuti passive pakhoma lamkati la chitoliro chachitsulo chopopera, zomwe zimapereka chitetezo chamagetsi ku substrate.

2. Mkati Wolimbitsa Woletsa Kudzikundikira
Kugwiritsa ntchito: Madzi ofewa, madzi okhala ndi asidi pang'ono, madzi okhuthala kwambiri, ndi mitundu ina ya madzi owononga
Zipangizo Zopangira Mkati: Simenti ya alumina yokhala ndi aluminiyamu yambiri, simenti yosagonjetsedwa ndi sulfure, simenti yopangidwa ndi matope + topcoat
Simenti yokhala ndi alumina wambiri: Chipinda cholimba chomwe chimagwiritsidwa ntchito kwambiri cholimbana ndi dzimbiri chomwe chimalimbana kwambiri ndi sulfate, choyenera kugwiritsidwa ntchito m'zimbudzi, m'madzi otayira, komanso m'madzi okhala ndi mankhwala.
Simenti yosagonjetsedwa ndi sulfate: Yosagonjetsedwa ndi sulfate, yoyenera madzi omwe ali ndi sulfate.
Chisindikizo cha Epoxy cha Simenti Chopaka Simenti: Chopaka cha epoxy chopangidwa ndi madzi chimapopedwa ndikupakidwa pamwamba pa chopaka simenti. Chimapereka kukana dzimbiri bwino ndipo chimaonetsetsa kuti madzi omwe atumizidwawo sali odetsedwa.

3. Mkati Mwapadera Wophimba
Kugwiritsa Ntchito: Koyenera kugwiritsidwa ntchito mwapadera kwambiri kapena madzi abwino owononga, madzi otayira m'mafakitale, komanso makamaka madera ouma, komwe ubwino wa zinthuzo ndi waukulu.
Zipangizo Zopangira Mkati: Polyurethane, epoxy ceramic lining. Yolimba kwambiri, yosagwira dzimbiri, komanso yosagwira mankhwala, imapereka malo osalala komanso osakoka kwambiri, ikukwaniritsa zofunikira zachilengedwe.

Kukonza simenti: Pambuyo popaka utoto wa centrifugal, chitoliro chokhala ndi simenti chimayikidwa pamalo otentha a 20±3℃ ndi chinyezi choposa 95% kuti chikhale cholimba kwambiri. Mphamvu yokakamiza ya simenti ya simenti siili yochepera 50MPa patatha masiku 28 chikapangidwa.

Zofunikira pakuwongolera khalidwe la gawo lamkati loletsa dzimbiri la mapaipi achitsulo opangidwa ndi ductile

Chida choyesera: Simenti yophimba yonyamula yanzeru yoyezera makulidwe a ultrasonic
Muyezo woyenerera: Kukhuthala kwa simenti kuyenera kukwaniritsa zofunikira zomwe zili mu tebulo ili m'munsimu.

Zofunikira pa muyezo (ISO 2531, EN 545, GB/T 13295, EN 598 makulidwe a simenti (mm))

Chipinda chamkati chilibe thovu, kuyenda kwamkati, kutsetsereka, mchenga woyandama, kusinthasintha, kusweka, ming'alu, kumamatira chitsulo, ndi zinyalala. Ma chamfers a chipinda chamkati pa soketi ndi olondola komanso osalala.

Kawirikawiri, chophimba chamkati cha khoma choletsa dzimbiri cha mapaipi achitsulo opangidwa ndi ductile chiyenera kukhala ndi mphamvu yabwino kwambiri yolimbana ndi dzimbiri ndi madzi. Posankha mkati mwake, zinthu monga kuwononga kwa madzi oti anyamulidwe, kuchuluka kwa madzi, ndi kutentha kwa malo ogwirira ntchito ziyenera kuganiziridwa.DINSENikhoza kupatsa makasitomala njira zophikira zamkati zotsutsana ndi dzimbiri zomwe zimapangidwa mwamakonda kutengera malo osiyanasiyana ogwirira ntchito.
