Taw qhia:

PPH (Polypropylene Homopolymer) fittings yog cov khoom siv yas ruaj khov siv hauv ntau lub kav dej, tshwj xeeb tshaj yog rau kev thauj dej, tshuaj, thiab roj. Paub txog lawv qhov hnyav thiab tsis kam tiv thaiv corrosion, PPH fittings yog qhov zoo tagnrho rau kev siv hauv kev lag luam xws li kev ua tshuaj, kev ua liaj ua teb, thiab kev tsim kho. Lawv tuaj yeem tiv taus qhov kub thiab txias, ua rau lawv haum rau kev hloov pauv dej kub thiab txias. PPH fittings kuj yog ib qho yooj yim rau nruab thiab txuas nrog ntau lub kav dej, muab cov kev daws teeb meem zoo thiab muaj txiaj ntsig zoo rau kev tswj cov dej hauv ntau qhov chaw. Lawv lub neej ntev ua rau txo tus nqi kho.

Melt Flow Rate Test ntawm PPH Fittings

Melt flow rate (MFR) yog ib qho kev ntsuas tseem ceeb rau kev nkag siab txog cov txheej txheem ntawm PPH (Polypropylene Homopolymer) fittings. MFR ntsuas yooj yim npaum li cas cov polymer ntws thaum melted, muab cov ntaub ntawv tseem ceeb txog nws cov viscosity nyob rau hauv qhov tshwj xeeb kub thiab load tej yam kev mob. Tsab ntawv xov xwm no tshawb txog qhov tseem ceeb ntawm kev ntsuam xyuas cov dej ntws rau PPH fittings, cov txheej txheem kuaj, yam cuam tshuam rau MFR, thiab nws qhov cuam tshuam rau kev tsim khoom thiab kev ua haujlwm.

Qhov tseem ceeb ntawm Melt Flow Rate hauv PPH Fittings

Melt flow rate yog ib qho tseem ceeb qhia txog cov yam ntxwv ntawm lub polymer thaum ua. Rau PPH fittings, MFR ncaj qha cuam tshuam rau kev tsim khoom xws li txhaj tshuaj molding thiab extrusion. MFR siab dua qhia tias qis dua viscosity, uas feem ntau ua rau kev ua haujlwm yooj yim dua thiab nrawm dua. Hloov pauv, MFR qis dua qhia cov khoom tuab uas yuav xav tau ntau lub zog los ua cov txheej txheem. Kev nkag siab txog MFR ntawm PPH pab cov tuam txhab ua kom zoo dua cov txheej txheem, txo cov nqi tsim khoom, thiab ua kom cov khoom zoo sib xws. Tsis tas li ntawd, MFR muab kev nkag siab txog cov khoom siv kawg ntawm cov khoom siv, ua rau cov kws ua haujlwm kwv yees seb cov fittings yuav ua li cas nyob rau hauv ntau yam xwm txheej.

Cov txheej txheem xeem rau Melt Flow Rate

Lub melt flow rate ntawm PPH fittings yog txiav txim siab siv cov txheej txheem kev sim, feem ntau txhais los ntawm ASTM D1238 lossis ISO 1133. Hauv qhov kev sim no, ib qho tshwj xeeb ntawm PPH granules tau muab tso rau hauv ib lub taub rhaub uas kub tau teem raws li qib polymer. . Tom qab ntawd tus qauv hnyav yog siv rau cov khoom siv, tso cai rau nws ntws los ntawm ib qho chaw tshwj xeeb. Qhov loj ntawm melted polymer uas extrudes los ntawm lub orifice tshaj lub sij hawm teem yog ntsuas. Cov txiaj ntsig tau nthuav tawm hauv grams ib kaum feeb (g / 10 min) thiab qhia txog cov khoom ntws. Ua raws li cov qauv kev sim ua kom muaj kev ntseeg siab thiab sib piv ntawm cov txiaj ntsig ntawm cov khoom sib txawv thiab cov chaw tsim khoom.

Cov yam ntxwv cuam tshuam rau Melt Flow Rate

Ob peb yam tuaj yeem cuam tshuam cov yaj ntws ntawm PPH fittings. Qhov kub thiab txias yog ib qho kev hloov pauv tseem ceeb tshaj plaws; Raws li qhov kub nce, qhov viscosity ntawm cov polymer txo, ua rau MFR siab dua. Tsis tas li ntawd, qhov hnyav molecular ntawm PPH kuj ua lub luag haujlwm tseem ceeb; siab dua molecular hnyav feem ntau ua rau qis qis qis vim yog nce viscosity. Lub xub ntiag ntawm additives thiab fillers tuaj yeem cuam tshuam ntxiv rau MFR, vim lawv tuaj yeem hloov pauv cov yam ntxwv ntawm cov dej ntws. Kev nkag siab txog cov xwm txheej no tso cai rau cov tuam txhab tsim kho lawv cov qauv tsim thiab kev ua haujlwm kom ua tiav cov kev xav tau yaj ntws rau cov ntawv thov tshwj xeeb.

Kev cuam tshuam rau kev tsim khoom thiab kev ua haujlwm

Cov txiaj ntsig ntawm kev ntsuas cov dej ntws muaj qhov cuam tshuam ncaj qha rau kev tsim khoom thiab kev ua haujlwm ntawm PPH fittings. Cov khoom siv nrog MFR tsim nyog yog qhov tseem ceeb rau kev ua tiav cov dej ntws zoo sib xws thaum ua tiav, uas cuam tshuam rau qhov tseeb qhov tseeb thiab cov khoom siv tshuab ntawm cov khoom tiav. Fittings uas tsim los ntawm cov polymers uas tsim nyog MFRs feem ntau yuav ua kom pom qhov zoo ib yam thiab kev ua haujlwm zoo, txo qhov kev pheej hmoo ntawm qhov tsis xws luag. Tsis tas li ntawd, MFR tuaj yeem cuam tshuam cov fittings 'muaj peev xwm tiv taus ntau yam kev ntxhov siab ib puag ncig, xws li kub hloov pauv thiab raug tshuaj lom neeg. Yog li, kev kuaj MFR yog ib feem tseem ceeb ntawm cov txheej txheem kev lees paub zoo hauv PPH haum tsim khoom.
