Yuav ua li cas txiav txim siab seb cov khoom siv caster muaj cov khoom lag luam zoo tshaj?

Cov qauv tseem ceeb rau kev txiav txim siab lub brittle tiv thaiv cov khoom siv caster

Brittle tiv taus yog hais txog cov ntaub ntawv muaj peev xwm los tswj kev nruj thiab tiv taus kev puas tsuaj hauv qis qis, kev ntxhov siab, lossis cuam tshuam. Cov txheej txheem tseem ceeb yog raws li hauv qab no:

 

Cov ntaub ntawv nyiam:

High nkig tiv thaiv: cold - home resistant hloov roj hmab), nrog rau cov roj hmab uas muaj zog ntxiv rau (nitrile, silicone roj hmab).

 

Zam: zoo tib yam unmodified plastics (pa6, pp, PP, PP, PP, PE), thiab nyuaj rau brittle begiture thaum tsis kub.

 

Cov kev xeem tseem ceeb thiab ntsuas:

Tsawg {- kub cuam tshuam: Yuav tsum muaj cov khw tsim khoom los muab cov kev qhia kub qis (piv txwv li t t t }6, iso 179). Key Parameter: tsis tshua muaj zog> 5 kj / m² ntawm lub hom phiaj qis yog suav tias yog qhov zoo (piv txwv, -30℃siv).

 

Cov iav hloov ntsuas kub (tg): qhov kub tseem ceeb ntawm cov khoom uas muaj nkig. Yuav tsum muaj: Cov khoom lag luam TG

 

Tsawg - kev hloov pauv hnyav hloov: sim lub hardness (ntug dej a) ntawm chav sov thiab kub. Kev Txiav Txim Siab: Kev hloov ntawm tsawg dua lossis sib npaug ntawm 10% yog suav tias yog qhov zoo (piv txwv li 85A → tsawg dua lossis sib npaug rau 94a); Qhov hloov> 20% qhia tias muaj feem pheej hmoo siab ntawm embrittlementlementlement.

 

Tus qauv thiab lub ntsej muag:

Log Tsim: Cov Cheeb Tsam Kev Sib Koom nyuaj (cov npoo, cov lus sib tham) yuav tsum tau sib npaug thiab tsis txhob muaj cov ces kaum ntse. Xum ib qho -} Daim pwm log kom tsis txhob muaj cov qauv sib dhos.

Cov khoom siv cov khoom siv: Lub log nto yuav tsum muaj kev ywj pheej, impurities, lossis cov chaw tawv tawv, raws li cov tsis xws luag tuaj yeem yooj yim ua rau brittle crushing.

 

Kev txheeb xyuas thiab siv:

Muaj rau kev sim ua teb: Tom qab 24 teev ntawm qis {{1} {kub divenions los soj ntsuam kom tawg (shrinkage tsawg dua lossis sib npaug rau 1%).

 

Cov chaw tsim khoom ua yeeb yam: ua ntej tshaj tawm cov khoom uas muaj tsawg - qhov chaw cia khoom siv kub (xws li qis dua cov khoom siv txias) thiab muaj cov ntawv thov txias zoo sib xws.

 

Ntsiab lus ntawm Txheej Txheem Txiav Txim:

Cov ntaub ntawv xub pib: txias - tiv taus pu, ua kom tawv, txias} - tiv taus roj hmab.

 

Key Data: Ensure low-temperature impact strength >5 KJ / M², TG

 

Tus qauv: xyuas kom meej li cov ces kaum, sib xyaw ua ke, thiab tsis muaj qhov tsis xws luag.

 

Siv ntawv pov thawj ntawv pov thawj: Xaiv cov khoom uas muaj pov thawj qis - sov daim ntawv thov kev paub.

 

Cov txheej txheem saum toj no tuaj yeem ntsuas cov khoom keter cov khoom lag luam tawm tsam rau puag thiab ua kom muaj kev ua haujlwm txhim khu kev qha hauv cov khoom lag luam tsawg.
