HDPE resin yekugadzira pombi
HDPE resin yekugadzira pombi,
HDPE resin yemapombi, HDPE resin pombi giredhi, HDPE resin mutengesi,
HDPE pombi giredhi ine yakafara kana bimodal kugovera kwema molecular huremu.Iyo ine yakasimba creep resistance uye yakanaka chiyero chekuomarara uye kuoma.Inogara yakasimba uye ine sag yakaderera kana ichigadziriswa.Mapombi anogadzirwa uchishandisa iyi resin ane simba rakanaka, kusimba uye kupikisa kuramba uye yakanakisa pfuma yeSCG neRCP..
Iyo resin inofanira kuchengetwa munzvimbo yakaoma, yakaoma uye kure nemoto uye zuva rakananga.Hazvifanirwe kuunganidzwa pamhepo.Panguva yekufambisa, zvinhu zvacho hazvifanirwe kuvhenekerwa nezuva rakasimba kana kunaya uye hazvifanirwe kutakurwa pamwe chete nejecha, ivhu, zvimedu zvesimbi, marasha kana girazi.Kufambisa pamwe chete nezvinhu zvine chepfu, zvinopisa uye zvinopisa zvinorambidzwa zvachose.
Application
HDPE pombi giredhi inogona kushandiswa mukugadzirwa kwepombi dzekumanikidza, senge pombi dzemvura dzakamanikidzwa, mapaipi egasi emafuta uye mamwe mapaipi emaindasitiri.Inogona zvakare kushandiswa kugadzira mapaipi asina-kudzvanywa akadai semapaipi ane madziro ane mbiri, madziro anomonereka pombi, silicon-core pombi, pombi dzekudiridza dzekurima uye mapombi ealuminium emusanganiswa.Pamusoro pezvo, kuburikidza nereactive extrusion (silane cross-linking), inogona kushandiswa kugadzira crosslinked polyethylene pombi (PEX) yekupa mvura inotonhora uye inopisa.
Magiredhi uye kukosha kwakajairika
HDPE yakakwira crystallinity, isiri-polar thermoplastic resin.Kuonekwa kweiyo HDPE yepakutanga ine mukaka chena, imwe dhigirii yekupenya muchikamu chitete.PE ine yakanakisa kuramba kune mazhinji emumba uye maindasitiri makemikari.Mamwe marudzi emakemikari anogona kukonzera kuora kwemakemikari, senge corrosive oxidants (concentrated nitric acid), anonhuwirira hydrocarbons (xylene) uye halogenated hydrocarbons (carbon tetrachloride).Iyo polymer haina-hygroscopic uye ine yakanaka yekupikisa mutsi, inogona kushandiswa pakurongedza.HDPE ine yakanaka kwazvo magetsi emagetsi, kunyanya yakakwira dielectric simba rekudzivirira, kuitira kuti yakanyatsokodzera waya netambo.Makirasi epakati kusvika akakwira huremu hwemamorekuru ane huremu hwakanakisa hwekuramba patembiricha yekamuri uye kunyangwe patembiricha yakadzikira se -40F.
Nyaya dzinoda kutariswa mukushandiswa kwepombi yeHDPE
1, yekunze yakavhurika-yakagadzika, uko kune chiedza chezuva, zvinokurudzirwa kuita pekugara matanho.
2. Yakavigwa HDPE pombi yemvura yemvura, pombi DN≤110 inogona kuiswa muzhizha, kuisa nyoka zvishoma, DN≥110 pipeline nekuda kwekudzivirira kwevhu kwakakwana, inogona kudzivisa kupisa kwekupisa, hapana chikonzero chekuchengeta urefu hwepombi;Munguva yechando, hapana chikonzero chekuchengetedza urefu hwepombi.
3, HDPE pombi kuisirwa, kana nzvimbo yekushanda iri diki kwazvo (senge: pombi zvakanaka, kuvaka sirin'i, nezvimwewo), inofanirwa kushandisa magetsi ekubatanidza.
4. Kana iyo inopisa melt socket yakabatana, tembiricha yekudziya haifanire kunge yakakwira zvakanyanya kana kureba, uye tembiricha inofanirwa kudzorwa pa210±10 ℃, zvikasadaro zvinokonzeresa yakawandisa yakanyungudutswa slurry muzvikamu uye kuderedza mukati. dhayamita yemvura;Iyo pombi yekubatanidza kana pombi yejojo inofanira kuva yakachena kana soketi yaiswa, kana zvisina kudaro ichaita kuti soketi iparadze uye inodonha;Panguva imwecheteyo, kutarisisa kunofanirwa kubhadharwa kudzora Angle uye kutungamira kwepombi fittings kuti usaite rework.
5, hot melt butt connection, iyo voltage inodiwa pakati pe200 ~ 220V, kana voltage yakanyanyisa, ichaita kuti kupisa kweplate yekupisa kwakanyanya, magetsi akaderera, ipapo muchina webutt haugoni kushanda zvakanaka;Iyo butt inofanirwa kuenderana neiyo interface;kana zvisina kudaro, nzvimbo yebutt haina kukwana, kusimba kwejojo ye welding haina kukwana, uye flange haina kunaka.Kana iyo inopisa ndiro inopisa, iyo yepombi haina kucheneswa, kana kupisa ndiro ine tsvina yakaita semafuta uye sediment, izvo zvichaita kuti iyo interface iparadze uye inodonha.Nguva yekupisa inofanira kudzorwa zvakanaka.Nguva pfupi yekupisa uye kusakwana kwekupisa kupisa kwepombi kuchaita kuti musono we welding uve diki.Kurebesa kupisa nguva kuchaita kuti musono we welding ive wakakurisa uye unogona kugadzira virtual welding.
