High arambe achirema polyethylene: kushanda

Low arambe achirema polyethylene rinobudiswa kubva Yakanatswa ethylene, uye somunhu organometallic tiwedzere protrude triethylaluminum uye titanium tetrachloride. Nokuti polyethylene mudzimai indasitiri anoshandisa dzakasiyana rwokugadzirwa akawanda izvo yakasiyana mhando mazano, kuti reactor vanokwanisa, nzira rokuchenesa polyethylene pamusoro tiwedzere kushandiswa.

Michina

Kakawanda yakatakura kunze matanho matatu anotevedzana pamusoro: polymerization pamusoro ethylene, yokuzvinatsa wayo kubva tiwedzere uye yokupedzisira nokuomesa rikurumidze. Mushure afunge mhinduro kubva triethylaluminum uye titanium tetrachloride mu cyclohexane anowedzerwa uye peturu. Neshungu kusvika 50 C maviri muzana mhinduro yaipiwa kuti reactor, apo mhepo-vachasimudza ezvinhu akawedzera ethylene. Anokurudzira kunoita vakawanda chikamu ethylene kuti polyethylene polymerization.

Kubvisa tiwedzere kubva zvichiguma polymer akanga yakasvinwa kure manyowa zvinhu ukaparadzawo. The polyethylene centrifuge kusukwa kubva tiwedzere uchishandisa methanol.

Polyethylene kuti yakaderera kumanikidzwa pashure rinsing iri akasvina panze, uye pacho vari akawedzera fuma anatsiridze unhu. Nokuti kujekeswa stabilizer kushandiswa, ethylene glycol uye yavaibvisa nitrophosphate, uye kuti shinier, wakisi rikashandiswa.

Pakupedzisira, polyethylene iri pasi kuomesa uye granulation. Polyethylene pamusoro yakaderera kumanikidzwa anogadzirwa chimiro granules uye upfu.

Pombi dzakagadzirwa pasi arambe achirema polyethylene

Ivo inoshandiswa kuisa gasi, mapaipi uye mvura enyika.

Zvikwepa kugadzirwa nenzira chichiitwa extrusion nzira. Sezvo mbishi mashoko kugadzirwa polyethylene mu granules makabuda.

Zvemari dzakabudirira vanoshandisa pombi yakadaro inenge zvose hurongwa.

Zvikwepa HDPE regai kukanganisa mvura quality, nekuti dzomunyika masvingo nengura haina kuumbwa uye dzakaunganidza chicherwa munyu.

Low kumanikidzwa polyethylene awana kushanda mu mapaipi mugadziriro, sezvo zviri husingakwanisi nehasha zvinhu uye kuti mukuru tembiricha.

Zvikwepa Gas chiri haungazoparadzwi uye usaora chokupika ehupfumi kwenguva refu.

Mukurumari - mukuru mapaipi unhu kubva HDPE. Ndivo vakakatyamadzwa nemishonga, regai kuora uye regai nengura, regai kutsemuka nokupesvedzera yakakwirira uye vakaderera tembiricha. Hwavo upenyu basa iri emakore anoverengeka.

Polyethylene High kumanikidzwa nekaupenyu nyoro uye kwakavharwa nenyama. nenhumbi dzake achiri sparse urongwa pamusoro mamorekuru kuti kunonyanya inobata arambe achirema kwayo. LDPE zvakabudisa siyana mafirimu. Vane refu kwazvo quality, uye kavha zvinhu nani kuita zvichida ndiye kuwanikwa. It anochengeta uye anotsigira kuva rekuva zvivako kunyange panguva tembiricha kusvikira makumi matanhatu inegumi. Qualitative zvechadenga polyethylene handishanduki pasi pokudzora makemikari. Iye anogona yakavimbika agopfigira chigadzirwa kubva unyoro uye mvura mhute.
