HDPE utomoni kupanga mapaipi
HDPE utomoni kupanga mapaipi,
HDPE utomoni kwa mapaipi, HDPE utomoni chitoliro kalasi, Wopereka utomoni wa HDPE,
Kalasi ya chitoliro cha HDPE ili ndi kugawa kwakukulu kapena kugawanika kwa ma molekyulu.Imakhala ndi kukana kolimba kwamphamvu komanso kukhazikika bwino kwa kuuma komanso kulimba.Ndi yolimba kwambiri ndipo imakhala ndi sag yochepa pamene ikukonzedwa.Mapaipi opangidwa pogwiritsa ntchito utomoni uwu amakhala ndi mphamvu zabwino, zolimba komanso zolimba komanso zolimba za SCG ndi RCP..
Utoto uyenera kusungidwa m'nyumba yosungiramo madzi, youma komanso kutali ndi moto ndi dzuwa.Asamawunjikane panja.Panthawi yoyendetsa, zinthuzo zisawonongeke ndi dzuwa lamphamvu kapena mvula ndipo siziyenera kunyamulidwa pamodzi ndi mchenga, nthaka, zitsulo, malasha kapena galasi.Kuyendera limodzi ndi zinthu zapoizoni, zowononga komanso zoyaka moto ndizoletsedwa.
Kugwiritsa ntchito
HDPE chitoliro kalasi angagwiritsidwe ntchito kupanga mipope kuthamanga, monga mapaipi amadzi opsinjidwa, mapaipi gasi mafuta ndi mapaipi ena mafakitale.Itha kugwiritsidwanso ntchito popanga mapaipi osaponderezedwa monga mapaipi okhala ndi malata apawiri, mapaipi omangira makhoma, mapaipi a silicon-core, mapaipi amthirira waulimi ndi mapaipi apawiri a aluminiumplastics.Kuonjezera apo, kudzera mu extrusion yogwira ntchito (silane cross-linking), itha kugwiritsidwa ntchito popanga mapaipi ophatikizika a polyethylene (PEX) popereka madzi ozizira ndi otentha.
Magiredi ndi mtengo wake
HDPE ndi utomoni wonyezimira kwambiri, wopanda polar thermoplastic resin.Maonekedwe a HDPE yoyambirira ndi yoyera yamkaka, kusinthasintha kwina mu gawo lopyapyala.PE imatsutsana kwambiri ndi mankhwala ambiri apanyumba ndi mafakitale.Mitundu ina yamankhwala imatha kuwononga dzimbiri, monga ma corrosive oxidants (concentrated nitric acid), ma hydrocarbon onunkhira (xylene) ndi ma halogenated hydrocarbon (carbon tetrachloride).Polima si hygroscopic ndipo imakhala ndi kukana bwino kwa nthunzi, yomwe imatha kugwiritsidwa ntchito pakuyika.HDPE ili ndi mphamvu zabwino kwambiri zamagetsi, makamaka mphamvu ya dielectric ya insulation, kotero kuti ndiyoyenera kwambiri waya ndi chingwe.Makalasi olemera kwambiri a mamolekyulu apakati kapena apamwamba amakhala ndi mphamvu yolimbana ndi kutentha kwapakati komanso ngakhale kutentha kotsika mpaka -40F.
Zinthu zofunika kuziganizira pakugwiritsa ntchito chitoliro cha HDPE
1, kuyala panja, komwe kuli kuwala kwadzuwa, tikulimbikitsidwa kuchitapo pogona.
2. M'manda HDPE payipi madzi, payipi DN≤110 akhoza kuikidwa m'chilimwe, atagona njoka pang'ono, DN≥110 payipi chifukwa cha kukana nthaka mokwanira, akhoza kukana kupsinjika matenthedwe, palibe chifukwa kusunga chitoliro kutalika;M'nyengo yozizira, palibe chifukwa chosungira kutalika kwa chitoliro.
3, kuyika mapaipi a HDPE, ngati malo ogwirira ntchito ndi ochepa kwambiri (monga: chitsime cha payipi, kumanga denga, ndi zina zotero), ayenera kugwiritsa ntchito kugwirizana kwa magetsi.
4. Pamene socket yotentha yosungunuka ilumikizidwa, kutentha kwa kutentha sikuyenera kukhala kokwera kwambiri kapena motalika kwambiri, ndipo kutentha kuyenera kuyang'aniridwa pa 210 ± 10 ℃, apo ayi kungayambitse slurry yosungunuka kwambiri m'zigawo ndikuchepetsa mkati. m'mimba mwake wa madzi;Chitoliro cholumikizira chitoliro kapena cholumikizira chitolirocho chiyenera kukhala choyera pamene soketiyo yalowetsedwa, apo ayi izi zidzachititsa kuti soketiyo ithyoke ndi kutuluka;Panthawi imodzimodziyo, chisamaliro chiyenera kulipidwa kuti chiwongolere Angle ndi mayendedwe a zopangira zitoliro kuti apewe kukonzanso.
5, kutentha kusungunula matako kugwirizana, voteji chofunika pakati pa 200 ~ 220V, ngati voteji kwambiri, kuchititsa kutentha mbale kutentha kwambiri, voteji ndi otsika kwambiri, makina matako sangathe kugwira ntchito bwinobwino;Chidacho chiyenera kugwirizanitsidwa ndi mawonekedwe;apo ayi, malo a matako sikokwanira, mphamvu ya kuwotcherera olowa sikokwanira, ndipo flange si bwino.Chipinda chotenthetsera chikatenthedwa, mawonekedwe a chitoliro samatsukidwa, kapena mbale yotenthetsera imakhala ndi zonyansa monga mafuta ndi matope, zomwe zimapangitsa kuti mawonekedwewo aphwanyike ndikutuluka.Nthawi yotentha iyenera kuyendetsedwa bwino.Kutentha kwakanthawi kochepa komanso kusakwanira kwa kutentha kwa chitoliro kumapangitsa kuti msoko wowotcherera ukhale wocheperako.Kutentha kwanthawi yayitali kumapangitsa kuti msoko wowotcherera ukhale waukulu kwambiri ndipo ukhoza kupanga kuwotcherera kwenikweni.
