ISO 15874 PPR cov kav dej tau siv dav hauv cov khoom siv zawb vim yog qhov tsim nyog rau kev txhim kho cov teeb meem tsim kho thiab ua kom tau cov lus qhia txog kev txhim kho ntau yam thiab cov lus qhia no sib tham txog cov teeb meem ntawm cov teeb meem kev tsim khoom ntawm ISO 15874 PP kav dej, lawv cov laj thawj, thiab muaj peev xwm ua tau kev daws.
1. Uneven Phab Ntsa Thickness
Ib qho teeb meem hauv iso 15874 cl yeeb yeeb yeeb yeeb nkab ntau dua yog qhov tsis muaj zog ntawm cov qauv yeeb yaj kiab, tsis muaj peev xwm los ntawm cov khoom siv tsis muaj zog, lossis cov khoom kub tsis muaj tseeb.
Los daws qhov no, cov tuam ntxhab yuav tsum xyuas kom meej tias cov khoom siv hluav taws xob ruaj khov thiab kub} Tsis txhob sib txawv ntawm cov qauv siv hluav taws xob hauv cov qauv yeeb yaj kiab {}}
2. Nto qhov tsis xws luag
Cov tsis xws luag sab, xws li ntxhib textures, khawb, thiab cov npuas, ua rau lawv muaj kev cuam tshuam nrog cov kav dej, ua rau lawv muaj kev lom zem rau kev txi .
Cov khoom ua rau muaj feem xyuam nrog cov khoom sib xyaw, cov khoom siv hluav taws xob ua kom tsis txhob muaj cov khoom siv dawb huv thiab ua kom tsis txhob muaj cov khoom siv dawb huv.
3. Cov fusion fusion zoo
Fusion vuam yog thawj txoj kev rau koom nrog PPEpes Pipes {}} Cov teeb meem tsis muaj zog, lossis cov khoom siv tsis muaj zog, lossis paug rau ntawm cov pob zeb sib tsoo.
Txhawm rau kom ntseeg tau tias muaj zog Fusion, kom zoo vuam cov tswv yim yuav tsum tau muab khaws cia rau ntawm qhov tseeb kub thiab thiab cov khoom siv vuam
4. Kev cuam tshuam tsawg
PPR kav yuav tsum tau tiv thaiv sab nraud yam tsis muaj kev puas tsuaj rau kev thauj khoom tsis zoo, lossis kev ua haujlwm qis dua thaum lub sij hawm extrusion .
Txhawm rau txhim kho cov kev cuam tshuam tsis kam, cov khoom lag luam yuav tsum tau siv cov khoom siv kom txias thiab ua kom muaj zog ntxiv rau cov kav dej .
5. Yeeb Nkab Ruaj Ntseg
Deformation ntawm PPR cov kav dej tuaj yeem tshwm sim thaum ntim khoom lossis cov khoom siv hluav taws xob tsis sib xws, lossis tsis muaj peev xwm ua kom tsis muaj peev xwm ua kom muaj peev xwm ua kom muaj peev xwm ua kom muaj peev xwm ua kom muaj peev xwm ua kom muaj peev xwm ua kom muaj peev xwm ua kom muaj peev xwm ua kom muaj peev xwm ua kom haum
Txhawm rau tiv thaiv deformation, cov tuam ntxhab yuav tsum siv cov tshuab txias txias thiab tsis txhob muaj lub zog cua txias thiab muaj peev xwm pab tswj lawv cov duab {}}
6. Qhov seem tsis muaj tseeb
Qhov tseeb tiag yog qhov tseem ceeb rau PRP kav kom ntseeg tau tias muaj kev sib txawv ntawm cov teeb meem tsis muaj tseeb thiab muaj peev xwm ua kom muaj teeb meem thiab cov kab ke muaj peev xwm.
Cov tsis raug no feem ntau tshwm sim los ntawm kev tsis ruaj khov extrusters, tsis muaj kev tswj hwm cov khoom siv roj ntsha thiab cov kev hloov pauv tsis tu ncua tuaj yeem pab tswj cov yeeb nkab muaj qhov ntev.
7. Xim Txawv
Xim sib xws yog qhov tseem ceeb rau cov khoom lag luam thiab kev tswj hwm zoo} Txawm li cas los xij, cov kab mob PP tau ua rau muaj cov xim sib xyaw ua ke vim, lossis paug rau thaum muaj ntau yam.
Txhawm rau kom ua tiav cov xim tsis zoo, cov tuam txhab tsim khoom yuav tsum tau siv cov khoom sib xyaw ua ke thiab tsis muaj cov khoom siv khib nyiab zoo nkauj los ntawm cov xim nyoos tuaj yeem pab tswj cov xim zoo nkauj.
8. Oxidation thiab kev laus teeb meem
Sij hawm dhau los, PPR cov kav dej tuaj yeem ua rau oxidation thiab kev laus, txo cov kev coj ua kom nrawm rau cov txheej txheem laus .
Txhawm rau tiv thaiv kev laus thaum ntxov, yuav tsum siv UV-resistant ntxiv rau cov khoom siv uas muaj kev cia siab nyob rau hauv thaj chaw tsaus ntuj nti .
Tag
Ua cov kav dej peps zoo yuav tsum tau saib xyuas cov khoom siv ntau yam, xws li cov khoom siv tsis raug, xws li cov neeg tsim khoom siv tau ua haujlwm, xws li cov neeg tsim khoom siv tsis raug, xws li cov neeg tsim khoom lag luam muaj peev xwm ua tau cov kev tswj hwm cov khoom lag luam sab nrauv thiab cov neeg siv PPR kev cia siab .
