Npe: Kev tshawb fawb ntawm BRACTURE TAIS ntawm PPR cov kav dej thiab kev txhim kho nruj heev thev naus laus zis

Taw qhia:

Polypropylene Random Copolymer (PPR) yog siv dav hauv ntau yam kev lag luam vim lawv cov tshuaj lom neeg tsis kam, thiab lub neej ntev ntev. Txawm li cas los xij, kev nkag siab txog cov pob txha lov ntawm PPR cov roj thiab kev tsim cov thev naus laus zis txhawm rau txhim kho lawv cov tawv me me yog qhov tseem ceeb rau kev txhawb nqa lawv txoj kev ntseeg tau thiab tsis tu ncua. Kab lus no ua kom peb sib tham txog kev tshawb fawb ntawm pob txha lov ntawm PPR cov kav dej thiab ntau hom kev kawm rau kev txhim kho lawv cov kev nruj.

Saj nyuaj ntawm PPR kav:

Lub pob txha tawv tawv ntawm PPR cov pipes yog hais txog lawv lub peev xwm tiv thaiv tawg thiab tsis ua tiav hauv kev ntxhov siab. Nws yog qhov cuam tshuam los ntawm cov khoom siv xws li cov khoom muaj pes tsawg leeg, kev ua haujlwm, thiab kev ntxhov siab ib puag ncig. Nkag siab txog cov pob txha lov ntawm pep kav los ntawm kev soj ntsuam cov kev sim thiab kev ntsuas kev kub ntxhov rau kev ntsuas lawv cov kev ua tau zoo nyob rau hauv chaw thau khoom sib txawv.

Yam cuam tshuam cuam tshuam rau pob zeb nyuaj:

Ntau yam cuam tshuam rau cov pob txha lov ntawm PPR cov kav dej, suav nrog ntsuas kub, raug cov qauv tshuaj, thiab tsim qauv txheej txheem. Kev kub siab rau qhov kub tuaj yeem txo cov pob txha lov ntawm PPR cov kav dej, ua rau lawv muaj kev cuam tshuam ntau rau brittle buritture. Raug rau cov tshuaj muaj kuab txhoj puab kuj tuaj yeem ua rau cov khoom siv thiab txo qis tawv. Tsis tas li ntawd, cov qauv tsim ntawm cov qauv yeeb nkab, suav nrog phab ntsa thickness thiab geometry, plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws cov pob txha tawv.

Kev txhim kho kev txhim kho thev naus laus zis:

Ntau cov tswv yim tau tsim los txhim kho cov pob txha lov ntawm pep kav. Qhov no suav nrog kev sib koom ua ke ntawm cov neeg sawv cev ua ntu zus xws li elastomers lossis cuam tshuam hloov kho cov khoom siv pprifi kom txhim kho nws txoj kev tawm tsam kom tawg. Tsis tas li ntawd, cov txuj ci siab ua xws li kev tswj hwm kev taw qhia thiab annealing cov txheej txheem thiab txhim kho kev sib zog ntawm cov kav dej. Cov thev naus laus zis tsom mus rau txo cov kev cuam tshuam ntawm kev ntxhov siab sab nraud thiab txhim kho kev ntseeg tau ntawm PPR cov kav dej.

Kuaj thiab Tswjhwm Zoo:

Kev tswj kev ua kom zoo thiab kev sim cov kev cai yog qhov tseem ceeb rau kev ua kom muaj kev sib tsoo thiab tag nrho kev ua tau zoo ntawm PPR kav. Tsis yog-kev sim ua kev soj ntsuam, xws li kev tshuaj ntsuam xyuas ultrasonic, tuaj yeem ua haujlwm txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau kom cov kav dej 'toughness. Ib qho ntxiv, cov txheej txheem ntsuas qauv rau cov txheej txheem nyuaj, xws li ASTM D5045, muab ib qho kev txhim khu kev qha ntawm cov khoom siv tiv thaiv kom tawg thiab tsis ua tiav.

Yav tom ntej cov qauv thiab cov nyom:

Txoj kev txhim kho yav tom ntej ntawm PPP kav yuav ua ntxiv rau kev txhim kho lawv cov pob txha lov nyuaj thiab tag nrho cov khoom siv tshuab. Kev Tshawb Fawb rau cov polymer siab heev, nanocomposites, thiab cov khoom siv txhawb yuav pab txhawb kom muaj kev txhim kho cov kav dej nyuaj ntawm PPRes. Tsis tas li ntawd, kev sib koom ua ke ntawm kev twv ua qauv thiab cov kev siv dag zog yuav ua kom cov khoom tsim kho tshiab thiab kev ua tau zoo ntawm PPP kav dej nyob rau hauv kev ua haujlwm sib txawv. Kev hais txog cov kev txhawj xeeb kom muaj kev txhawj xeeb thiab ib puag ncig cuam tshuam kuj tseem ceeb rau ib qho tseem ceeb hauv kev txhim kho ntawm kev nruj dua thiab ntau dua ntawm cov khoom siv hluav taws xob nruj dua.

Xaus:

Hauv kev xaus, kev tshawb fawb ntawm BRACTURE TAIS ntawm PPP cov roj thiab kev txhim kho kev txhim kho todicness yog qhov tseem ceeb rau kev ntseeg tau thiab ntev ntawm cov tseem ceeb muaj cov khoom sib xyaw. Nkag siab txog qhov cuam tshuam nyuaj, kev siv cov kev tswj hwm nruj ua kom nruj kev ntsuas PPR Purnacic cov qauv yav tom ntej thiab kev daws cov kev sib tw tshwm sim los ntawm PPR cov cuab yeej ua haujlwm thiab sib koom ua ke rau kev txhim kho durability thiab kev ntseeg tau.
