Performance ＆ Zvakanakira
Mutsetse wekugadzira unogona kuona akawanda base pombi panguva imwe chete, kumhanyisa kusunungura, uye nekukurumidza uye zvakaenzana kuvhara iyo yekunze casing. Synchronous traction, kucheka-kubvisa uye kupedzwa chigadzirwa coiling inodzorwa nekombuta, ine yakakwira yekugadzira kumhanya uye kushanda nesimba.
HDPE pombi pombi inochinjika yepurasitiki yakagadzirwa ne thermoplastic high-density polyethylene inoshandiswa zvakanyanya kune yakaderera-tembiricha fluid uye gasi kutamisa. Munguva pfupi yapfuura, mapaipi eHDPE akawana kushandiswa kwawo kukuru kwekutakura mvura inonwiwa, tsvina ine ngozi, magasi akasiyana-siyana, slurry, mvura yemoto, mvura yemvura, nezvimwewo. Iyo yakasimba mamolecular bond yeHDPE pombi zvinhu zvinobatsira kuti ishandise kune yakakwirira-kudzvinyirira mapaipi. Mapombi epolyethylene ane nhoroondo refu uye yakasarudzika yebasa regasi, oiri, migodhi, mvura, uye mamwe maindasitiri. Nekuda kwehuremu hwayo hwakadzikira uye kukwirira kwekurara kuramba, iyo HDPE pombi indasitiri iri kukura zvakanyanya. Mugore ra1953, Karl Ziegler naErhard Holzkamp vakawana high-density polyethene (HDPE). HDPE mapaipi anogona kushanda zvinogutsa muhupamhi tembiricha siyana -2200 F kusvika +1800 F. Zvisinei, kushandiswa HDPE Mapaipi haatauri kana tembiricha yemvura inodarika 1220 F (500 C).
Mapaipi eHDPE anogadzirwa nepolymerization ye ethylene, ne-chigadzirwa chemafuta. Zvakasiyana-siyana zvekuwedzera (stabilizers, fillers, plasticizers, softeners, lubricant, colorants, flame retardants, blowing agents, crosslinking agents, ultraviolet degradable additives, etc.) zvinowedzerwa kuburitsa pombi yekupedzisira yeHDPE uye zvinhu. Kureba kwepombi yeHDPE kunogadzirwa nekudziisa iyo HDPE resin. Iyo inobva yawedzerwa kuburikidza nekufa, iyo inosarudza hupamhi hwepombi. Ukobvu hwePipe wall hunotarwa nemusanganiswa wesaizi yekufa, kumhanya kwescuru, uye kumhanya kwetirakita yekudhonza. Kazhinji, 3-5% kabhoni dema inowedzerwa kuHDPE kuti iite kuti UV isarambe, inoshandura mapaipi eHDPE kuita dema muruvara. Mamwe mavara akasiyana anowanikwa asi kazhinji haawanzo kushandiswa. Yemavara kana mitsetse HDPE pombi inowanzoita 90-95% zvinhu zvitema, uko mutsetse weruvara unopiwa pa5% yekunze.
