Dab tsi yog cov ntsiab lus tsim ntawm ib lub taub hau ntsia hlau

Lub taub hau ib leeg yog ib qho tseem ceeb ntawm cov khoom siv extrusion, thiab nws cov qauv tsim ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov txheej txheem extrusion thiab qhov zoo ntawm cov khoom kawg.

Cov hauv qab no yog cov ntsiab lus tsim ntawm ib lub taub hau ntsia hlau:

Kev xaiv khoom

• Mechanical kev ua tau zoo: Cov khoom siv yuav tsum muaj lub zog zoo txhua yam los tiv thaiv lub siab loj thaum lub sijhawm tsim khoom.
• Corrosion resistance: Cov khoom siv yuav tsum muaj kev tiv thaiv corrosion zoo rau cov yas ua tiav los tiv thaiv cov tshuaj lom neeg los ntawm kev cuam tshuam cov yas zoo.
• Hnav tsis kam: Vim qhov kev sib hloov tas li thiab kev sib txhuam ntawm cov ntsia hlau sab hauv lub thoob, nws yuav tsum tau ua kom cov khoom muaj kev hnav zoo los ua kom nws lub neej ua haujlwm ntev.

Cov khoom siv thoob

• Thickness: Phab ntsa thickness ntawm lub thoob yuav tsum tau xaiv raws li kev ua hauj lwm siab thiab kub, thiab cov tuab phab ntsa cylinder txoj kev xav feem ntau yog siv rau lub zog xam.
• Kev kub siab ua haujlwm: Lub thoob yuav tsum muaj peev xwm tiv taus qhov kub thiab txias ib puag ncig thiab feem ntau yog ua los ntawm cov hlau tsis muaj cua sov.
• Hnav tsis kam: Xav txog kev sib txhuam mus sij hawm ntev nrog cov ntsia hlau, cov khoom siv phom yuav tsum muaj kev hnav zoo.
• Ntsia taub hau
• Kev txiav txim siab loj: Txoj kab uas hla ntawm cov ntsia hlau yog nyob ntawm qhov loj me ntawm cov khoom ua tiav, hom yas ua tiav, thiab cov khoom tsim tau.

Pub seem tsim

• Qhov tob ntawm kev pub noj seem ntsia hlau zawj: xam qhov tob ntawm qhov chaw pub mis ntsia hlau zawj raws li qhov kev txiav txim siab ntsia hlau compression piv rau kev ua kom zoo tshaj qhov khoom muaj peev xwm.
• Compression ratio thiab groove tob
• Geometric compression ratio: Qhov sib piv compression thiab zawj qhov tob ntawm cov ntsia hlau yuav tsum tau txiav txim siab raws li cov ntaub ntawv empirical lossis cov qauv dav dav thaum tsim.

Ntsia taub hau hom

• Xov seem zoo: Feem ntau, cov xov trapezoidal yog siv, nrog txoj kab nqes ntawm 10 degree mus rau 15 degree thiab ib lub vojvoog ntawm 0.07 txog 0.13 millimeters.
• Tus naj npawb ntawm cov ntsia hlau taub hau
• Ntau lub taub hau xov thiab ib lub taub hau xov: Ntau lub taub hau xov muaj qhov zoo ntawm cov khoom siv thiab muaj peev xwm tuav tau cov ntaub ntawv, tab sis ntau lub taub hau threads yuav ua rau txo qis ntawm cov khoom zoo. Yog li ntawd, qhov cuam tshuam ntawm cov khoom zoo yuav tsum tau txiav txim siab thaum txhim kho kev ua haujlwm.

Kev tsim ntawm ib lub taub hau ib leeg yog txheej txheem nyuaj uas muaj ntau yam xws li xaiv cov khoom siv, kev tsim qauv, thiab kev siv tshuab. Cov neeg tsim qauv yuav tsum tau ua tib zoo xav txog yam xws li kev tsim muaj peev xwm, kev siv hluav taws xob, thiab kev pabcuam lub neej ntawm extruders, thaum xyuas kom meej tias lub thoob tuaj yeem ua haujlwm ruaj khov hauv qhov kub thiab txias ib puag ncig kom ua tau raws li qhov yuav tsum tau ua ntawm cov yas sib txawv.
