Chitoliro cha Epoxy cha FRP
Mafotokozedwe Akatundu
Chitoliro cha epoxy cha FRP chimadziwika kuti chitoliro cha Glass Fiber Reinforced Epoxy (GRE). Ndi chitoliro cha zinthu zopangidwa ndi zinthu zambiri, chopangidwa pogwiritsa ntchito njira yozungulira kapena yofanana, chokhala ndi ulusi wagalasi wamphamvu kwambiri ngati chinthu cholimbitsa ndi epoxy resin ngati matrix. Ubwino wake waukulu ndi monga kukana dzimbiri (kuchotsa kufunika kwa zokutira zoteteza), kulemera kopepuka kuphatikiza ndi mphamvu yayikulu (kusavuta kukhazikitsa ndi kunyamula), kutentha kochepa kwambiri (kupereka kutchinjiriza kutentha ndi kusunga mphamvu), komanso khoma lamkati losalala, losakulira. Makhalidwe amenewa amachititsa kuti chikhale cholowa m'malo mwa mapaipi achikhalidwe m'magawo monga mafuta, mankhwala, uinjiniya wa m'madzi, kutchinjiriza magetsi, ndi chithandizo cha madzi.
Zinthu Zamalonda
Chitoliro cha FRP Epoxy (Glass Fiber Reinforced Epoxy, kapena GRE) chimapereka kuphatikiza kwabwino kwambiri kwa zinthu poyerekeza ndi zipangizo zachikhalidwe:
1. Kukana Kwambiri Kudzimbiritsa
- Chitetezo cha Mankhwala: Cholimba kwambiri ku zinthu zosiyanasiyana zowononga, kuphatikizapo ma acid, alkali, mchere, zimbudzi, ndi madzi a m'nyanja.
- Yopanda Kukonza: Sikufuna zophimba zamkati kapena zakunja kapena chitetezo cha cathodic, makamaka kuchotsa kukonza ndi zoopsa zokhudzana ndi dzimbiri.
2. Kulemera Kopepuka ndi Mphamvu Yaikulu
- Kuchuluka Kochepa: Kulemera kwake ndi 1/4 mpaka 1/8 yokha ya chitoliro chachitsulo, zomwe zimapangitsa kuti zinthu ziyende bwino, kunyamula, ndi kuyika zikhale zosavuta, zomwe zimachepetsa ndalama zonse zomwe zimagwiritsidwa ntchito pa ntchito.
- Mphamvu Yapamwamba ya Makina: Ili ndi mphamvu yolimba, yopindika, komanso yogwira ntchito, yokhoza kuthana ndi kupsinjika kwakukulu kwa ntchito ndi katundu wakunja.
3. Makhalidwe Abwino Kwambiri a Hydraulic
- Bore Yosalala: Pamwamba pa chipindacho pali chiwopsezo chochepa kwambiri cha kukangana, zomwe zimachepetsa kwambiri kutayika kwa mutu wamadzimadzi komanso kugwiritsa ntchito mphamvu popopera poyerekeza ndi mapaipi achitsulo.
- Kusakulitsa: Khoma losalala limalimbana ndi kukanikiza kwa sikelo, matope, ndi bio-fouling (monga kukula kwa nyanja), zomwe zimapangitsa kuti madzi aziyenda bwino pakapita nthawi.
4. Katundu wa Kutentha ndi Magetsi
- Kuteteza Kutentha: Kuli ndi kutentha kochepa kwambiri (pafupifupi 1% ya chitsulo), komwe kumapereka chitetezo chabwino kwambiri kuti kuchepetse kutaya kapena kuchulukitsa kutentha kwa madzi otumizidwa.
- Kuteteza Magetsi: Kumapereka mphamvu zabwino kwambiri zotetezera magetsi, zomwe zimapangitsa kuti zikhale zotetezeka komanso zoyenera kugwiritsidwa ntchito m'malo opangira magetsi komanso olumikizirana.
5. Kulimba ndi Mtengo Wochepa wa Moyo
- Nthawi Yaitali Yogwira Ntchito: Yopangidwira moyo wautumiki wa zaka 25 kapena kuposerapo pansi pa mikhalidwe yabwinobwino yogwirira ntchito.
- Kusamalira Kochepa: Chifukwa cha dzimbiri lake komanso kukana kukula, dongosololi silifuna kukonza nthawi zonse, zomwe zimapangitsa kuti likhale ndi ndalama zochepa pa moyo wonse.

Mapulogalamu Ogulitsa
- Mizere Yotumizira Mphamvu Yapamwamba: Imagwiritsidwa ntchito ngati njira zotetezera zingwe zamagetsi zapansi panthaka kapena pansi pa madzi.
- Malo Opangira Magetsi/Malo Osungira Magetsi: Amagwiritsidwa ntchito kuteteza zingwe zamagetsi ndi zingwe zowongolera mkati mwa siteshoniyo ku dzimbiri la chilengedwe ndi kuwonongeka kwa makina.
- Chitetezo cha Zingwe Zolumikizirana: Chimagwiritsidwa ntchito ngati njira zotetezera zingwe zolumikizirana zomwe zili m'malo oyambira kapena ma network a fiber optic.
- Ma Tunnel ndi Milatho: Amayikidwa kuti aike zingwe m'malo ovuta kuyendamo kapena okhala ndi zinthu zovuta, monga malo owononga kapena chinyezi chambiri.
Kuphatikiza apo, chitoliro cha FRP epoxy (GRE) chimagwiritsidwa ntchito kwambiri m'mafakitale monga mapaipi opangira zinthu zowononga kwambiri komanso madzi otayira. Pakupanga malo opangira mafuta, chimagwiritsidwa ntchito popanga zinthu zowononga kwambiri monga mizere yosonkhanitsira mafuta osakonzedwa, mizere yojambulira madzi/polymer, ndi jakisoni wa CO2. Pakugawa mafuta, ndi chinthu choyenera kwambiri pa mapaipi apansi panthaka ya gasi ndi malo osungira mafuta. Kuphatikiza apo, ndi chisankho chabwino kwambiri cha madzi ozizira a m'nyanja, mizere yoletsa moto, ndi mizere yotulutsa madzi ochulukirapo komanso odzaza ndi madzi amchere m'mafakitale ochotsa mchere m'madzi.
