China Ultra-Durable Polyurethane (PU) Plastic-Reinforced Spiral Corrugated Hose fekitori nevatengesi

Hosipaipi yePolyurethane (PU) Yakasimba Zvakasimba Yepurasitiki Yakasimbiswa Nesimbi Inotenderera Mufananidzo Wakaratidzwa

Hosipaipi yePolyurethane (PU) Yakasimba Yepurasitiki Yakasimbiswa Nesimbi

Pombi yePolyurethane (PU) Plastic-Reinforced Spiral Corrugated Hose ipayipi inoshanda zvakanyanya, ine mabasa akawanda yakagadzirwa kuti isangane nezvinodiwa zvakanyanya zvemaindasitiri, mabhizinesi, uye zvekurima. Chimiro chayo chikuru chinosanganisa madziro emukati ePU akapfava, anodzivirira kupera simba nesimbi yakabatanidzwa yepurasitiki (kana waya yesimbi yakaputirwa nemhangura kuti iparare), ichipa chiyero chisina kuenzana chekuchinjika, simba, uye kugara kwenguva refu.

st, kuumbwa kwezvinhu zvayo kunovimbisa kugara kwenguva refu: PU tube (yakavakirwa papolyester) ine kuomarara kweShore A kwe95±2, ichipa simba rekudzivirira kukweshwa, kubvaruka, uye kukanganiswa—zvishandiso zverabha kana PVC zvinoshanda kupfuura 3-5 mune zviitiko zvinopfekwa zvakanyanya (semuenzaniso, kutamisa zvinhu zvakaita sesimende kana zviyo). Kusimbiswa kwepurasitiki kunobvisa kudiwa kwewaya dzesimbi dzinorema (kunze kwekunge zvataurwa) ukuwo kuchichengetedza chimiro chayo, zvichiita kuti hose ikwanise kumira kumanikidzwa kwakanaka kusvika ku10 bar uye kumanikidzwa kwakaipa (kusveta) kwe -0.9 bar, zvichiita kuti ive yakakodzera kutakura uye kubata zvinhu zvinobva muvacuum.
Chechipiri, inopa mukana wakakura wekuchinjika kwezvakatipoteredza: inoshanda zvakavimbika mukupisa kuri pakati pe -40°C kusvika 90°C (nekutsungirira kwenguva pfupi kusvika 120°C), inoramba ichichinjika kunyangwe kuchitonhora zvakanyanya (kusiyana nemapombi ePVC akaomarara) uye inoramba kuchinja munzvimbo dzinopisa zvakanyanya. Pamusoro pezvo, vhezheni yemhando yechikafu (inoenderana neEU 10/2011 uye FDA standards) haina phthalates, BPA, uye heavy metals, zvichiita kuti ive yakachengeteka kutamisa zvinwiwa zvinodyiwa (majusi, waini, mukaka) kana zvinhu zvekudya zvakaoma—zvakakosha pakugadzira chikafu uye kugadzira zvinwiwa. Pakushandiswa kwemaindasitiri, inoratidza kusasimba kwemakemikari kumafuta, maasidhi manyoro, alkalis, uye solvents, ichidzivirira kuora mumamiriro ekushanda akaoma.
Chechitatu, dhizaini yayo inotarisisa mushandisi inowedzera kushanda zvakanaka: rusvingo rwemukati rwakatsetseka (Ra < 0.5 μm) runoderedza kurasikirwa kwekukweshana, ruchiita kuti mvura, hupfu, kana magasi zvisavharike zvakanaka ukuwo ruchidzivirira kuunganidzwa kwezvimedu (zvichiita kuti kuchenesa kuve nyore uye kuderedza mari yekugadzirisa). Kugadzirwa kwakareruka (≈30% kwakareruka kupfuura mahosi erabha ane dhayamita imwe chete) uye chimiro chespiral chinodzivirira kink zvinobvumira kufamba-famba, kukotama, uye kumonereka zviri nyore—zvakanakira nzvimbo dzakamanikana (semuenzaniso, kufefetera kwemuchina, nzvimbo dzeinjini dzengarava) kana mashandisirwo emota (semuenzaniso, masprayers ekurima, mapombi ekuvaka). Saizi dzinogadziriswa (dhayamita yemukati: 25mm–300mm; ukobvu hwemadziro: 0.6mm–2mm) uye sarudzo dzemavara (dzakajeka, nhema, kana dzakagadzirirwa) dzinoenderana nezvinodiwa chaizvo, kubva pakufambiswa kwemvura murabhoritari diki kusvika pakutakura slurry yemugodhi mukuru.
