Isu tiri nyanzviconveyor roller vagadzirimuChina.HDPE Roller ndechimwe chezvigadzirwa zvedu zvinopisa.Zvinhu zvakasiyana-siyana zvemagiredhi akasiyana-siyana eHDPE ndiwo akakodzera kusanganiswa kwezvinhu zvina zvakakosha: density, molecular weight, molecular weight distribution, uye additives.Akasiyana catalysts anoshandiswa kugadzira tsika yakakosha polymer.Izvi zvakasiyana-siyana zvinosanganiswa kugadzira HDPE mamakisi ekushandisa kwakasiyana;kuwana chiyero chakanakisa mukuita.
1. Extrusion: Magiredhi anoshandiswa pakugadzira extrusion kazhinji ane melt index isingasviki 1 uye yepakati kusvika yakafara MWD.Iyo yakaderera MI inopa yakakodzera kunyungudika simba panguva yekugadzirisa.Iyo yakafara giredhi yeMWD inonyanya kukodzera kuextrusion nekuda kwekumhanya kwayo kwepamusoro kwekugadzira, kuderera kwekufa uye kuderedzwa kunyungudika kutsemuka.
HDPE ine akawanda extrusion application senge waya, tambo, hoses, tubing uye profiles.Mapombi epombi anotangira padiki-chikamu machubhu eyero egasi chaiwo kusvika kune makobvu-akavezwa matema machubhu emaindasitiri nemapaipi emadhorobha anosvika 48 in.Machubhu machubhu akakura dhayamita mahombe emadziro anoshandiswa seimwe nzira yemvura inonaya uye mimwe mitsetse yetsvina yakagadzirwa nekongiri kuti ikure nekukurumidza.
Sheets uye thermoforming: Iwo thermoformed linings akawanda makuru epikiniki-mhando reefers akagadzirwa neHDPE yekuomarara, kureruka uye kusimba.Mamwe mapepa uye zvigadzirwa zve thermoformed zvinosanganisira mafenda, matangi liner, magadhi ematireyi, mabhokisi ekutumira nemagaba.Huwandu hukuru hwekukurumidza kukurumidza mashizha ekushandisa ari muvhavha kana dziva pasi, izvo zvinoenderana nekuoma kweMDPE, makemikari kuramba uye kusamira.
2. Blow molding: Inopfuura 1/3 yeHDPE inotengeswa muUnited States inoshandiswa pakuputira zvinangwa.Izvi zvinobva kumabhodhoro ane bleach, mafuta emota, detergents, mukaka nemvura yakadirwa kusvika kumafiriji mahombe, matangi emafuta emota nemagaba.Blow molding giredhi hunhu senge kunyungudika simba, ES-CR uye kuoma kwakafanana neaya anoshandiswa pepa uye thermoforming maapplication, saka mamakisi akafanana anogona kushandiswa.

Jekiseni-blow molding inowanzoshandiswa kugadzira midziyo midiki yekurongedza mishonga, shampoos uye zvizorwa.Imwe mukana weiyi maitiro ndeye otomatiki kona yemabhodhoro, pasina kudikanwa kwematanho ekupedzisira-ekupedzisira seyakajairika kuvhuvhuta.Kunyangwe mamwe mamakisi akatetepa eMWD achishandiswa kuvandudza kupera kwepasi, epakati kusvika pahupamhi MWD mamakisi anowanzo shandiswa.
3. Injection molding: HDPE ine akawanda maapplication kubva kune anogona kushandiswa zvakare akatetepa-walled zvinwiwa makapu kusvika ku5-gsl cans, iyo inodya 1/5 yeHDPE inogadzirwa mudzimba.Majekiseni ekuumba magiredhi anowanzo ane melt index ye5 kusvika 10, uye ane giredhi repamusoro rekuyerera rine yakaderera kuoma giredhi uye processability.
4. Rotational molding: Zvishandiso zvinoshandisa nzira iyi yekugadziridza zvinowanzodimburwa kuita hupfu hunofanira kunyungudutswa uye kuyerera mumhepo inopisa.HDPEs kazhinji ane densities kubva 0.935 kusvika 0.945 g/cc uye ane nhete MWD nokuda yakakwirira simba uye shoma warpage, ine melt indices kazhinji kubva 3-8.Akakwira MI mamakisi kazhinji haashande nekuti iwo haana iwo anodiwa maitiro uye kwezvakatipoteredza kusagadzikana kuparara kwekupokana kwezvigadzirwa zverotomoulded.
HDPE zvinhu zvinogadziriswa kuita HDPE pombi neextrusion tekinoroji.Iyo pombi inoshandiswa munzvimbo dzakawanda uye inoshandiswa kugadzira HDPE isina basa.Inogona kutamba yakanaka anti-corrosion basa uye inowanzoshandiswa munzvimbo dzine acid uye alkali, dzakadai semiti yemafetiraiza.Kana uchida mamwe mashoko pamusoro pebelt conveyor idler roller,taura nesu.
