Chitoliro Chotenthetsera Pansi cha PE-RT
Chiyambi cha Chitoliro Chotenthetsera Pansi cha PE-RT
Mapaipi otentha a pansi a Gaoke a PE-RT amapangidwa ndi zida zochokera ku Krauss Maffei ndi Battenfeld-Cincinnati ku Germany, ndipo zinthu zopangira zomwe zimatumizidwa kuchokera ku SK ku South Korea, LG ku South Korea ndi fakitale ya Basel Swiss ku Germany (zopangira zapadera zapakati pa polyethylene PE-RT DX800 floor heating Pipe) zimatulutsidwa kudzera muukadaulo wapamwamba wopanga. Gulu lililonse la zinthu limayesedwa mwamphamvu kuti zitsimikizire kuti zinthu zili bwino komanso zotetezeka. Nthawi yomweyo, zinthu za kampaniyo zapambana mayeso opitilira a kuthamanga kwa mpweya kwa maola 8,760 a National Chemical Building Materials Testing Laboratory.
Mapaipi otenthetsera pansi a Gaoke PERT ali ndi makhalidwe okhazikika bwino pakugwira ntchito, otetezeka kwambiri komanso osavuta kukonza. Amakwaniritsa zofunikira za chitetezo chapamwamba, kuyika kosavuta komanso kukonza mapaipi otenthetsera pansi omwe amawala. Ali ndi kukana kutentha kwambiri komanso kukana kugwedezeka, ndipo ndi otsika mtengo kwambiri. Kugwira ntchito bwino ndi bwino kuposa mapaipi ena. Pakadali pano ndi chitoliro chaukhondo kwambiri komanso choteteza chilengedwe.
Kugawa kwa Mapaipi Otenthetsera Pansi a PE-RT
Pali zinthu 16 zonse za mapaipi otenthetsera pansi a PE-RT, zomwe zagawidwa m'magawo 4 kuchokera ku dn16-dn32. Zinthuzi zagawidwa m'magawo 5 malinga ndi kupanikizika: PN 1.0MPa, PN 1.25 MPa,
PN 1.6 MPa, PN 2.0 MPa ndi PN 2.5 MPa. Zipangizo zamadzi zili ndi zida zonse ndipo zinthuzi zimagwiritsidwa ntchito potenthetsera madzi.
Makhalidwe a Chitoliro Chotenthetsera Pansi cha PE-RT
1. Zipangizo zopangira zabwino kwambiri komanso chitsimikizo cha khalidwe: zipangizo zopangira zomwe zimatumizidwa kuchokera ku South Korea zimagwiritsidwa ntchito popanga, ndipo chinthu chilichonse chomalizidwa chimayesedwa mpweya pamalopo pa mphamvu ya 0.8MPa kuti zitsimikizire kuti zinthuzo ndi zabwino komanso zodalirika.
2. Moyo wautali wautumiki: pansi pa mikhalidwe ya kutentha kogwira ntchito 70℃ ndi kupanikizika 0.4MPa, ingagwiritsidwe ntchito mosamala kwa zaka zoposa 50.
3. Kutenthetsa kwabwino: Kutenthetsa kwabwino ndi 0.4W/mK, komwe kuli kwakukulu kwambiri kuposa PP-R's 0.21W/mK ndi PB's 0.17W/mK, zomwe zingasunge mphamvu zambiri pakutenthetsa.
4. Phunzitsani kutentha kwa dongosolo: kutayika kwa kukangana pa khoma lamkati la chitoliro ndi kochepa, mphamvu yonyamulira madzi ndi yokwera ndi 30% kuposa ya mapaipi achitsulo a mulifupi womwewo, ndipo kuthamanga kwa kutentha kwa dongosolo ndi kochepa.
5. Njira yolumikizira ndi yosinthasintha komanso yosavuta kuyiyika: ikhoza kukhala yolumikizana ndi kusungunuka kwa madzi kapena yolumikizana ndi makina. Njira yolumikizira ndi yosinthasintha komanso yosavuta kuyiyika, pomwe PE-X imatha kulumikizidwa ndi makina okha.
6. Kutentha kochepa: Chitolirochi chimakhala ndi kukana kutentha kochepa ndipo chingapangidwe ngakhale kutentha kutsika nthawi yozizira, ndipo chitolirocho sichifunika kutenthedwa chikapindika.
7. Kapangidwe ndi kukhazikitsidwa kosavuta: kali ndi kusinthasintha kwabwino, ndipo sipadzakhala "kubwerera m'mbuyo" ikapindika, komwe kuli kosavuta kumangidwa ndi kugwiritsidwa ntchito; chitolirocho chimapindika, chomwe ndi chosavuta kumanga ndikuyika.
8. Kukana kwabwino kwambiri kwa kugwedezeka: Kukana kwa kugwedezeka ndi kuwirikiza kasanu kuposa mapaipi a PVC-U. Chogulitsachi sichimawonongeka mosavuta panthawi yomanga ndipo chili ndi chiopsezo chochepa cha chitetezo.
