zvigadzirwa

Ongororo yezvakagadzirwa zvinhu zveHDPE kaviri madziro mabhero,
HDPE resin yemabhero maviri-madziro, Ungasarudza sei HDPE resin yemabheji maviri emadziro,

Zvinodiwa zvakajairika zvezvinhu zve polyethylene (PE) zvinosanganisira kunyungudika kuyerera (MFR), density, flexure elastic modulus uye oxidation induction nguva (OIT), simba rekuita, nezvimwewo. , volatiles uye imwe oxidation induction nguva inosarudza nguva yekukuvara kwe oxidation.Kune mabhero anoda makore makumi mashanu ekushandiswa, kudzora iyo oxidation induction nguva yezvakagadzirwa ndiyo kiyi yekuona hupenyu hwesevhisi hwemakore makumi mashanu.Zvinonyatsotsanangurwa muGB/T19472.1-2004 kuti oxidation induction nguva yezvakagadzirwa zvemabhero inofanira kunge iri ≥20min(200℃).

Iyo elastic modulus yeHDPE resin ine simba rakakura pakuoma kwemhete.Zvishandiso zvine yakakwira elastic modulus zvinogona kuvandudza iyo mhete kuomarara kwezvigadzirwa, asi zvakare chengetedza zvigadzirwa uye kuderedza mutengo pasi pemamiriro ekuona kuoma kwemhete.Saka mukugadzirwa kweHDPE kaviri-madziro mabhero, iyo mbishi inoshandiswa inofanira kunge iine yakakwira modulus yekunyungudika.Saizi yekunyungudika kuyerera kunoratidza saizi yehuremu hwema molecular.Kazhinji kutaura, zvinhu zvine yakakwira melt kuyerera mwero inokodzera kugadzirisa uye kuumba, uye inogona kuvandudza kugadzirwa kwakanaka.Zvisinei, haigoni kuva yakakura zvikuru, iyo ine simba guru pakuoma kwemhete.Panguva imwecheteyo, inofanirwa kuve nehupamhi hwepamusoro uye yakanaka yekugadzirisa kuita uye kuchinjika kwemidziyo.

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.
