ibicuruzwa

yahinduwe igishushanyo mbonera cya polyethylene inzogera nini ya diameter nini,
HDPE kumurongo, HDPE kumuyoboro ucuramye,

Ibicuruzwa byakozwe hifashishijwe ikoranabuhanga rya UNIPOL.Yagenewe gukoreshwa mumashanyarazi aho imbaraga ndende za hydrostatike hamwe no kurwanya gukura buhoro buhoro.Ibisabwa bikenerwa birimo imiyoboro ya gazi isanzwe, imiyoboro minini ya diametre inganda, ubucukuzi bw'amabuye y'agaciro, imyanda, hamwe n'imirongo y'amazi ya komini.Ibipimo ngenderwaho byinganda: ASTM D 3350: gutondekanya selile - Kamere - PE345464A - Umukara - PE345464C (Reba ICYITONDERWA A) Ikigo gishinzwe imiyoboro ya plastike (PPI): TR-4 - Umuyoboro Kamere - DGDB-2480 NT 3408 - ASTM PE3608 icyiciro - 1600psi HDB @ 73 ° F. - DGDB-2480 NT 3608 - Umuyoboro wirabura - DGDB-2480 BK 3608 (Reba ICYITONDERWA B) Reba amabwiriza kugirango ubone ibisobanuro birambuye.ICYITONDERWA: (A) Imibare itanu yambere ya selile yashyizwe mubyiciro bishingiye kubisanzwe.Umubare wanyuma ninzandiko zishingiye kubirabura byirabura (resin naturel wongeyeho 6.5% DFNF-0092)..

Gukoresha

1.Gukoresha porogaramu
2.Imiyoboro isanzwe yo gukwirakwiza gazi
3.Imiyoboro minini ya diameter
4.Ubucukuzi
5.Umwanda
6. Imirongo ya serivisi ishinzwe amazi

HDPEinzogera, izwi ku izina rya PE curragted pipe, ni ubwoko bushya bwumuyoboro woroheje wakozwe na polyethylene yuzuye. Ifite ibiranga uburemere bworoshye, kurwanya umuvuduko ukabije, gukomera kwiza, kubaka byihuse no kuramba.

Diameter ya HDPE inzogera ebyiri zakozwe mu Bushinwa ni φ400 ~ φ1400mm, ntibisaba gusa ibintu byinshi bitemba neza kugirango byuzuze ibisabwa byo gutunganya ibikoresho, ariko kandi byujuje ibisabwa kugirango urwego rukomeye rwibicuruzwa (icyiciro cya S2 kirenze 8KN . ibicuruzwa ntibishobora kugera kuri 8KN / m2. Agaciro kipimisha impeta yubushyuhe busanzwe (23 ± 2 ℃) ni 6.2kN / m2, bisaba guhindura ibikoresho kandi bisaba ko utagabanije imikorere ya HDPE2480 yumwimerere. Ni ukuvuga, muburyo bwo kwemeza impeta ihindagurika, ingaruka zubushyuhe buke hamwe nimbaraga zingaruka zibicuruzwa; Kunoza modulus yunamye yibikoresho kugirango harebwe urwego rwibicuruzwa bikomeye.
Igikorwa cyo gukora kugirango cyuzuze cyane cyahinduwe cyibanze cya kalibiri nini cyane ya polyethylene inzogera ishobora kuzuza ibisabwa bya kaliberi nini ya kaliberi impeta ihindagurika, ingaruka zubushyuhe buke, imbaraga zidasanzwe hamwe no kunama bipfa.
Kuvangwa na 30-50% D50 = 2-7 ​​μm ultrafine calcium karubone na 50-70% ya ultrafine talc ifu, ifu ya compte yarateguwe.
Umubare wuzuye wibikoresho byingenzi byahinduwe bikozwe mubikoresho byifu yifu birashobora kugera kuri 50% muri HDPE nini ya diameter.Ukurikije imiterere ya HDPE∶ ibikoresho bishya byahinduwe = 50∶50, uburemere bwumuyoboro hamwe na kalibiri imwe bwiyongera 5 ~ 6% gusa, kandi modulus yayo yunamye igera kuri 1360Mpa.Kurwanya imbaraga hamwe ningaruka ziterwa nibikoresho bifite imbaraga zingana na 24Mpa bisa nkibyahinduwe bwa mbere iyo byuzuyemo 30%: imbaraga zingana ni ≥24Mpa, naho guturika kwingero 10 zifite imbaraga zo guhangana na 0 ℃ ni munsi ya 1, yujuje byuzuye ubuziranenge bwibisabwa binini binini bya HDPE.
Koresha 30 ~ 50% D50 = 2 ~ 7μm ya karubone ya calcium ya karubone na 50 ~ 70% ya feri ya talc ya talc kugirango uvange mu ifu igizwe n’ibice 100, wongereho 0.2 ~ 1 igice cyo guhuza ifu yimbuto hanyuma ukabyutsa iminota 5 ~ 10 kuri 120 ~ 140 ℃.Noneho ongeramo ibice 3 ~ 6 byamavuta yera, 1 ~ 2 bya acide stearic, 1 ~ 2 byamavuta ya hydroxyl silicone hamwe na 20 ~ 30 bya polyethylene cyangwa polypropilene bivanga neza nyuma yibikoresho, kuri 150 ~ 190 ℃ ubushyuhe, unyuze kuri parallel twin screw extruder ivanze no kuvanga.
Kugirango uhuze ubunini bwa masterbatch no kugabanya imyanda n ivumbi mugikorwa cyo kubyara, igishushanyo mbonera cyaciwe kandi kigenzurwa numwuka kugirango ubone ubunini buke.
Umukozi uhuza ni titanate ihuza cyangwa aluminate ihuza cyangwa agent ya silane.
