Mu mafakitale amakono, mapaipi ndi ofunika kwambiri popatsira zinthu, ndipo ma flange (zolumikizira zazikulu) amatha kutayikira, kupopera madzi ndi dzimbiri. Zoteteza ma flange zimakhala ngati zotchinga zosaoneka kuti zitsimikizire kuti ntchitoyo ndi yotetezeka komanso kuteteza antchito ndi zida.
1. Kodi aMlonda wa Flange?
Amatchedwanso zoteteza ku flange splash, ndi zowonjezera zaukadaulo zotetezera kulumikizana kwa flange. Zopangidwa ndi PVC/TPU yowonekera bwino, zimakhala ndi kukana kutentha kwambiri/kotsika, kukana kung'ambika komanso kukana nyengo, zoyenera madera osiyanasiyana amafakitale. Ndi kuwala kopitilira 90%, zimalola kuyang'aniridwa ndi maso popanda kusokoneza.
2. Ntchito Zoteteza Zapakati
•Kuteteza Kuphulika kwa Madzi: Kumatchinga kutulutsa madzi m'malo otentha kwambiri, owononga kapena oopsa kuti ateteze antchito ndi zida.
•Chenjezo Loyamba Kutuluka kwa Madzi: Ma model apamwamba ali ndi ma specs osintha mtundu wa pH kuti adziwitse nthawi yake za kutuluka kwa madzi pang'ono.
•Kukana Kudzikundikira: Kumachotsa chinyezi ndi fumbi, kumawonjezera nthawi yogwira ntchito ya flange ndikuchepetsa ndalama zokonzera.
•Chenjezo la Chitetezo: Mizere yowunikira bwino imathandiza kuti zinthu ziwonekere bwino m'malo otsetsereka kapena okwera kwambiri.
3. Zochitika Zogwiritsira Ntchito
Zingasinthidwe malinga ndi kukula kwa flange (DN15-DN2000), kupanikizika (PN10-PN100), kutentha (-30℃ mpaka 180℃) ndi zoulutsira mawu, zomwe zimaphatikizapo mankhwala, mphamvu, magwiridwe antchito apadera ndi mafakitale wamba.
4. Zolemba Zogwiritsira Ntchito
•Sankhani chitsanzo choyenera kutengera momwe ntchito ikuyendera.
•Ikani moyenera kuti zitsimikizire kuti zimamatirira bwino.
•Yang'anani nthawi zonse ndipo sinthani zinthu zomwe zawonongeka mwachangu.
• Sinthani zoteteza zakale/zosweka (zaka 1-3 panja, zaka zoposa 5 mkati).
5. Chidule
Zoteteza ma flange ndizofunikira kwambiri pachitetezo cha mafakitale. Mitundu yokhazikika komanso yowoneka bwino yakhala zida zokhazikika, kuteteza chitetezo cha kupanga ndi kusankha ndi kukonza koyenera.
Nsalu Yopangira Fumigation
Nsalu yopangira fumigation (yomwe imatchedwanso fumigation sheet) ndi chinthu cholemera kwambiri chomwe chimagwiritsidwa ntchito popanga malo obisala mpweya m'malo oteteza tizilombo komanso kupha tizilombo toyambitsa matenda pogwiritsa ntchito mpweya.
Zipangizo Zazikulu
•HDPE: Yopyapyala, yopepuka, yopanda mpweya, yotsika mtengo, yogwiritsidwa ntchito kamodzi/kanthawi kochepa.
•Yokutidwa ndi PVC: Yolimba, yolimba, yogwiritsidwanso ntchito, yabwino kwambiri panja/pantchito zolemera.
•Multi-layer Composite: Mpweya wochepa wolowa m'malo, chitetezo chachikulu, poika anthu m'zidebe.
Ubwino
Kuteteza tizilombo moyenera, kuteteza chilengedwe, kusunga ndalama komanso kusinthasintha.
Momwe Mungagwiritsire Ntchito
1. Phimbani mwamphamvu cholingacho ndi nsalu yofukiza fumigation.
2. Tsekani m'mphepete ndi tepi/matumba a mchenga kuti mpweya usalowe.
3. Ikani mankhwala ophera utsi mkati mwa malo otsekedwa.
4. Tsekani kuti muchotse tizilombo toononga.
5. Tsegulani ndi kupumitsa mpweya mpaka mpweya utasungunuka bwino.
