Kodi pali kusiyana kotani pakati pa chitoliro cha PU ndi chitoliro chachitsulo chopangidwa ndi simenti?

Mapaipi achitsulo opangidwa ndi ductileZokutidwa ndi PU ndi simenti ndi mitundu iwiri yodziwika bwino ya zomatira zodzimbidwa, zomwe zimasiyana makamaka ndi zipangizo zawo zomatira, momwe zimagwirira ntchito, komanso momwe zimagwiritsidwira ntchito. Zonsezi zimakwaniritsa cholinga chachikulu: kuteteza chitoliro ku dzimbiri kuchokera kuzinthu zomwe zimanyamulidwa ndikuwonetsetsa kuti madzi/madzimadzi ndi abwino. Zotsatirazi zikufotokoza kusiyana pakati pa zitoliro ziwirizi zomatira zomatira.

Ntchito Yaikulu:

• Chitoliro chachitsulo chopangidwa ndi simenti: Amagwiritsidwa ntchito makamaka pa madzi osaphika, madzi akumwa, mapaipi a zimbudzi otsika mphamvu;
• Chitoliro chachitsulo chopangidwa ndi ductile cha PU: Zimbudzi zowononga, kuchotsa mchere m'madzi a m'nyanja, madzi otayira m'mafakitale, mayendedwe othamanga kwambiri;

Njira Yopewera Kudzikundikira:

• Chophimba cha simenti cha ductile chitsulo: Filimu yodzaza ndi alkaline passivation komanso kudzipatula kwa thupi;
• Chophimba cha polyurethane chachitsulo chopangidwa ndi ductile: Chophimba chokhuthala komanso chosagwira ntchito bwino cha mankhwala, sichilowa m'malo mwake;

Katundu Wapamwamba:

• Chitoliro chachitsulo chopangidwa ndi simenti: Koyelo yolimba K≈0.03mm, yosavuta kuikulitsa;
• Chitoliro chachitsulo chopangidwa ndi ductile cha PU: Malo osalala, roughness coefficient K <0.01mm, palibe kukula, kutayika pang'ono kwa hydraulic;

Kukana Kukwiya/Kukhudzidwa:

• Chitoliro chachitsulo chopangidwa ndi simenti:Kawirikawiri, zimatsukidwa mosavuta ndi tinthu tolimba;
• Chitoliro chachitsulo chopangidwa ndi ductile cha PU：Yokwera kwambiri, imatha kunyamula zinthu zokhala ndi mchenga ndi slag;

Kusinthasintha kwa Kutentha:

• Chitoliro chachitsulo chopangidwa ndi simenti：0 – 80℃；
• Kuphimba ndi Kuphimba kwa Polyurethane pa Chitoliro cha Iron Ductile: -40 – 120℃；

Kalasi Yaukhondo:

• Chitoliro chachitsulo chopangidwa ndi simenti:Tsatirani miyezo ya madzi akumwa;
• Chitoliro chachitsulo chopangidwa ndi ductile chopangidwa ndi PU:Yopanda zosungunulira, yopanda VOC, yovomerezeka ndi NSF/WRAS, ndipo ingagwiritsidwe ntchito pakumwa madzi mwachindunji;

Moyo wa Utumiki:

• Chitoliro chachitsulo chopangidwa ndi simenti:Zaka ≥50;
• Chitoliro chachitsulo chopangidwa ndi ductile cha PU:Zaka ≥100 ndi nthawi yayitali yopanda kukonza;

Mtengo Wonse:

• Chitoliro chachitsulo chopangidwa ndi simenti:Mtengo wotsika komanso wosavuta kupanga;
• Chitoliro chachitsulo chopangidwa ndi ductile cha PU:Mtengo wokwera koma mtengo wotsika wa moyo wonse;

Chipinda cha simenti ndi chotsika mtengo komanso chosinthika, choyenera kugwiritsidwa ntchito m'madzi wamba; Chipinda cha PU "chopanda madzi okwanira + cholimba kwambiri" ndiye chisankho choyamba cha dzimbiri lalikulu, kuthamanga kwa madzi ambiri komanso nthawi yayitali.Lumikizanani nafekuti mudziwe zambiri za momwe mungasankhire chitoliro cha DI choyenera.
