Qhov cuam tshuam ntawm kev xaiv cov khoom ntawm cov yas Extruder kev ua tau zoo: Xaiv cov khoom zoo

Taw qhia

Kev xaiv ntawm resin tuaj yeem muaj kev cuam tshuam loj rau kev ua haujlwm ntawm cov yas extruder. Txoj cai resin tuaj yeem pab txhim kho qhov zoo ntawm cov khoom extruded, ua kom cov khoom ua tau zoo, thiab txo cov nqi. Hauv tsab xov xwm no, peb yuav tham txog qee yam uas yuav tsum tau xav txog thaum xaiv cov resin rau yas extruder.

Khoom Khoom

Thawj kauj ruam hauv kev xaiv cov resin yog xav txog cov khoom siv uas yuav tsum tau ua rau daim ntawv thov. Qee cov khoom tseem ceeb muaj xws li:

• Lub zog:Lub zog ntawm cov resin yuav txiav txim siab npaum li cas qhov hnyav ntawm cov khoom extruded tuaj yeem txhawb nqa.
• Kev nruj:Lub zog ntawm cov resin yuav txiav txim siab npaum li cas cov khoom extruded yuav deflect nyob rau hauv load.
• Impact resistance:Qhov cuam tshuam tsis kam ntawm cov resin yuav txiav txim siab zoo npaum li cas cov khoom extruded yuav tiv taus raug poob los yog ntaus.
• Kub tiv taus:Qhov kub tsis kam ntawm cov resin yuav txiav txim siab npaum li cas cov khoom extruded yuav tiv taus cua sov.
• Tshuaj tiv thaiv:Cov tshuaj tiv thaiv ntawm cov resin yuav txiav txim siab npaum li cas cov khoom extruded yuav tiv taus cov tshuaj.

Kev txiav txim siab ua

Ntxiv nrog rau cov khoom siv, nws tseem ceeb heev uas yuav tsum xav txog kev txiav txim siab thaum xaiv cov resin. Qee qhov kev txiav txim siab ua haujlwm tseem ceeb suav nrog:

• Melt Flow Index (MFI):MFI yog ib qho kev ntsuas uas yooj yim npaum li cov resin ntws thaum nws yaj. Lub MFI siab dua yuav ua rau cov nqi extrusion sai dua.
• viscosity:Lub viscosity ntawm cov resin yog ib qho kev ntsuas ntawm qhov resistant cov resin ntws. Qhov qis viscosity yuav ua rau kev ua haujlwm yooj yim dua.
• Cov iav hloov pauv kub (Tg):Lub Tg yog qhov kub thiab txias uas cov resin hloov los ntawm cov khoom tawv, nkig mus rau cov khoom muag, rubbery. Kev ua haujlwm kub yuav tsum siab tshaj Tg rau cov resin ntws kom zoo.

Compatibility nrog Additives

Qee cov resins tau sib xws nrog cov khoom ntxiv uas tuaj yeem txhim kho lawv cov kev ua tau zoo. Qee cov tshuaj additives muaj xws li:

• Fillers: Fillers tuaj yeem siv los txhim kho lub zog, nruj, thiab qhov ruaj khov ntawm cov khoom extruded.
• Reinforcements: Reinforcements, xws li iav fibers los yog carbon fibers, yuav siv tau los txhim kho lub zog thiab nruj ntawm cov khoom extruded.
• Pigments: Pigments tuaj yeem siv los ntxiv xim rau cov khoom extruded.
• UV stabilizers: UV stabilizers tuaj yeem siv los tiv thaiv cov khoom extruded los ntawm UV hluav taws xob.

Nqi

Tus nqi ntawm cov resin yog lwm qhov tseem ceeb uas yuav tsum tau xav txog. Resins tuaj yeem sib txawv ntawm tus nqi ntawm ob peb duas las ib phaus mus rau pua pua las ib phaus. Tus nqi ntawm cov resin yuav nyob ntawm seb cov khoom siv, kev txiav txim siab, thiab kev sib raug zoo nrog cov khoom ntxiv.

Xaus

Kev xaiv ntawm resin yog qhov kev txiav txim siab tseem ceeb uas tuaj yeem cuam tshuam loj rau kev ua haujlwm ntawm cov yas extruder. Los ntawm kev ua tib zoo xav txog cov khoom siv, kev txiav txim siab, kev sib raug zoo nrog cov khoom siv ntxiv, thiab tus nqi, koj tuaj yeem xaiv cov resin zoo rau koj daim ntawv thov.
