HDPELub tshuab raj, lub npe hu ua PE curragted yeeb nkab, yog ib yam tshiab ntawm lub teeb yeeb nkab ua los ntawm cov polyethylene siab ntom ntom.
Txoj kab uas hla ntawm HDPE ob-phab ntsa bellows tsim nyob rau hauv Suav teb yog φ400 ~ φ1400mm, uas tsis tsuas yog yuav tsum tau high fluidity ntawm cov ntaub ntawv kom tau raws li qhov yuav tsum tau ntawm cov khoom, tab sis kuj ua tau raws li qhov yuav tsum tau ntawm lub nplhaib stiffness qib ntawm cov khoom (S2 chav kawm ntawv yog ntau tshaj 8KN. / m2, rau qee yam khoom siv, qhov loj ntawm txoj kab uas hla, qhov qis dua lub nplhaib txhav, yog li qhov no ua rau muaj kev nyuaj rau kev xaiv cov ntaub ntawv. Cov khoom tsis tuaj yeem ncav cuag 8KN / m2. Lub nplhaib txhav qhov ntsuas tus nqi ntawm tus qauv ntsuas kub (23 ± 2 ℃) yog 6.2kN / m2, uas yuav tsum tau hloov kho cov khoom siv thiab xav kom tsis txhob txo qhov kev ua tau zoo ntawm thawj HDPE2480. Nyob rau hauv cov xwm txheej ntawm kev ua kom lub nplhaib hloov tau yooj yim, qhov kub tsis tshua muaj kev cuam tshuam thiab kev cuam tshuam lub zog ntawm cov khoom; Txhim kho qhov khoov modulus ntawm cov ntaub ntawv kom ntseeg tau qib ntawm cov khoom nruj.
Kev tsim cov txheej txheem rau siab filling hloov masterbatch ntawm loj caliber siab ceev polyethylene bellows uas muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm loj caliber bellows nplhaib saj zawg zog, tsis tshua muaj kub cuam tshuam, notch cuam tshuam lub zog thiab tej yam dabtsi yog khoov tuag.
Sib xyaw nrog 30-50% D50 = 2-7 μm ultrafine calcium carbonate thiab 50-70% ultrafine talc hmoov, cov hmoov sib xyaw tau npaj.
Qhov ntim ntawm cov khoom siv hloov pauv ua los ntawm cov khoom siv hmoov sib xyaw tuaj yeem ncav cuag 50% hauv HDPE loj-inch bellows.Raws li qhov xwm txheej ntawm HDPE∶ cov khoom siv tshiab hloov tshiab = 50∶50, qhov hnyav ntawm cov yeeb nkab nrog tib lub caliber nce tsuas yog 5 ~ 6%, thiab nws cov qauv khoov yog mus txog 1360Mpa.Lub tensile thiab cuam tshuam tsis kam ntawm cov khoom uas muaj zog flexural ntawm 24Mpa zoo ib yam li cov khoom qub hloov thaum nws tau ntim nrog 30% : lub zog tensile yog ≥24Mpa, thiab cov rupture naj npawb ntawm 10 cov qauv nrog kev cuam tshuam ntawm 0 ℃ tsawg dua 1, uas ua tau raws li qhov yuav tsum tau ua ntawm qhov loj-caliber HDPE bellows.
Siv 30 ~ 50% D50 = 2 ~ 7μm superfine calcium carbonate thiab 50 ~ 70% superfine talc hmoov los sib tov rau hauv 100 feem ntawm cov hmoov sib xyaw, ntxiv 0.2 ~ 1 feem sib txuas tus neeg sawv cev rau hauv cov hmoov sib xyaw thiab nplawm rau 5 ~ 10 feeb ntawm 120 ~ 140 ℃.Tom qab ntawd ntxiv 3 ~ 6 qhov chaw ntawm cov roj dawb, 1 ~ 2 qhov chaw ntawm stearic acid, 1 ~ 2 qhov chaw ntawm hydroxyl silicone roj thiab 20 ~ 30 feem ntawm polyethylene los yog polypropylene do tusyees tom qab cov khoom, ntawm 150 ~ 190 ℃ kub, los ntawm lub parallel ntxaib ntsia hlau extruder nws tov extrusion thiab granulating.
Txhawm rau sib koom ua ke qhov loj ntawm masterbatch thiab txo cov khib nyiab thiab plua plav hauv cov txheej txheem tsim khoom, cov masterbatch raug txiav thiab tshuaj xyuas los ntawm huab cua kom tau txais qhov loj me me.
Tus neeg sawv cev sib txuas yog tus neeg sawv cev titanate coupling lossis aluminate coupling tus neeg saib xyuas lossis silane coupling tus neeg sawv cev.
