HDPEmabhero, anozivikanwa se PE curragted pipe, rudzi rutsva rwepombi yakareruka yakagadzirwa nepamusoro density polyethylene.Iine hunhu hwehuremu huremu, kusimba kwakanyanya, kusimba kwakanaka, kuvaka nekukurumidza uye hupenyu hurefu.

Iyo dhayamita yeHDPE yakapetwa kaviri-madziro mabhero anogadzirwa muChina ndeye φ400 ~ φ1400mm, iyo isingangoda yakakwira fluidity yezvinhu kuti isangane nezvinodiwa zvekugadzirisa zvemidziyo, asi zvakare inosangana nezvinodiwa zvekuomarara giredhi rezvigadzirwa (S2 kirasi yakakura kupfuura 8KN /m2, kune chimwe chinhu, iyo yakakura dhayamita, yakaderera kukosha kwemhete yemhete.Saka izvi zvinounza kumwe kuoma pakusarudzwa kwezvinhu.Mushure mekuedza kwakawanda, Qilu HDPE2480 inogona kuzadzisa zvido zvayo zvekugadzira, asi kuoma kwemhete chigadzirwa hachikwanisi kusvika 8KN / m2. Kuoma kwemhete bvunzo kukosha pachiyero tembiricha (23 ± 2 ℃) ndeye 6.2kN / m2, iyo inoda kuchinjwa kwezvinhu uye inoda kuti pasina kuderedza kushanda kweiyo HDPE2480 yepakutanga. pasi pemamiriro ekuona kuchinjika kwemhete, yakaderera tembiricha kukanganisa uye notch kukanganisa simba rechigadzirwa; Kuvandudza kubhenda modulus yezvinhu kuti ive nechokwadi chegiredhi rekuomarara kwechigadzirwa.
Iyo yekugadzira nzira yekuzadza yakakwira yakagadziridzwa masterbatch yehombe yakakwira density polyethylene mabhero ayo anogona kusangana nezvinodiwa zvehombe caliber mabhero mhete kuchinjika, yakaderera tembiricha maitiro, notch simba rekuita uye kumwe kukotama kunofa.
Yakasanganiswa ne 30-50% D50 = 2-7 ​​μm ultrafine calcium carbonate uye 50-70% ultrafine talc powder, iyo yakagadzirwa poda yakagadzirwa.
Huwandu hwekuzadza hweakagadziridzwa master material yakagadzirwa necomposite poda zvinhu inogona kusvika 50% muHDPE hombe-dhayamita mabhero.Pasi pemamiriro eHDPE∶ nyowani yakagadziridzwa master material = 50∶50, huremu hwepombi ine caliber yakafanana inowedzera 5 ~ 6% chete, uye modulus yayo yekupeta inosvika 1360Mpa.Iko kusimba uye kupesvedzera kupikisa kwezvinhu zvine simba rekushanduka-shanduka kwe24Mpa kwakafanana neiyo yepakutanga yakagadziridzwa zvinhu kana yakazadzwa ne30%: iyo tensile simba iri ≥24Mpa, uye kuputika nhamba yemasampuli gumi ane mhedzisiro yekupikisa pa0℃ iri pasi pe1, iyo inonyatsozadzisa zvinodiwa zvemhando hombe-caliber HDPE mabhero.
Inoshandisa 30 ~ 50% D50 = 2 ~ 7μm superfine calcium carbonate uye 50 ~ 70% superfine talc powder kusanganisa muchikamu che100-chikamu chehupfu, kuwedzera 0.2 ~ 1 chikamu chekubatanidza muhupfu hwehupfu uye kumutsa kwemaminitsi mashanu kusvika gumi 120 ~ 140 ℃.Wobva wawedzera 3 ~ 6 zvikamu zvemafuta machena, 1 ~ 2 zvikamu zve stearic acid, 1 ~ 2 zvikamu zve hydroxyl silicone mafuta uye 20 ~ 30 zvikamu zve polyethylene kana polypropylene inomutsa zvakaenzana mushure mechinhu, pa150 ~ 190 ℃ tembiricha, kuburikidza ne parallel twin screw extruder yayo yakasanganiswa extrusion uye granulating.
Kuti ubatanidze saizi ye masterbatch uye kuderedza marara uye guruva mukugadzira maitiro, iyo masterbatch inotemwa uye inoongororwa nemhepo kuti iwane yakafanana particle size.
Iyo coupling agent ndeye titanate coupling agent kana aluminate coupling agent kana silane coupling agent.
