Crosslinking koom nrog tsim kev sib raug zoo ntawm cov saw hlau polymer, uas ua rau muaj peb-dimensional network uas txhim kho kev ua haujlwm zoo. Piv txwv li, crosslinked PPH fittings pom muaj zog tensile ntau dua thiab tsis kam mus deformation piv rau cov uas tsis yog-crosslinked variants. Kev nkag siab txog cov kev sib raug zoo no tso cai rau cov tuam txhab tsim kho cov txheej txheem tshuaj kom ua tiav cov khoom siv kho tshuab uas xav tau, ua PPH fittings tsim nyog rau kev thov.
Kev cuam tshuam ntawm cov tshuaj lom neeg ntawm cov cuab yeej cuab tam
Thaum PPH fittings muaj npe nrov rau lawv cov tshuaj tiv thaiv, kev cuam tshuam rau cov tshuaj lom neeg tseem tuaj yeem cuam tshuam lawv cov khoom siv kho tshuab thaum lub sijhawm. Ntev ntev raug rau qee cov kuab tshuaj lossis cov kua qaub tuaj yeem ua rau muaj kev ntxhov siab tawg, uas ua rau lub zog tag nrho ntawm cov khoom siv. Qhov tshwm sim no tshwm sim thaum cov tshuaj nkag mus rau hauv cov polymer matrix, tsim kom muaj qhov tsis muaj zog hauv cheeb tsam. Yog li ntawd, nws yog ib qho tseem ceeb los soj ntsuam qhov sib xws ntawm PPH fittings nrog cov tshuaj tshwj xeeb thaum lub sij hawm tsim. Ua cov kev ntsuam xyuas kev laus sai tuaj yeem pab kwv yees seb cov tshuaj lom neeg puas tuaj yeem cuam tshuam rau cov khoom siv kho tshuab, ua rau cov kws ua haujlwm tsim cov khoom siv hluav taws xob ntau dua rau lawv cov ntawv thov.
Cov Txheej Txheem Ua Haujlwm thiab Kev Ua Haujlwm Zoo
Cov txheej txheem tshuaj lom neeg koom nrog hauv kev tsim khoom ntawm PPH fittings, xws li kev txhaj tshuaj molding thiab extrusion, kuj ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab lawv cov tshuab ua haujlwm. Cov txheej txheem ua haujlwm, suav nrog qhov kub thiab txias, siab, thiab txias txias, tuaj yeem cuam tshuam cov crystallinity thiab molecular orientation ntawm polymer. Piv txwv li, kev ua haujlwm kub ntau dua tuaj yeem ua rau cov crystallinity nce ntxiv, ua rau muaj zog thiab khov kho. Hloov pauv, kev ua haujlwm tsis raug tuaj yeem ua rau muaj qhov tsis xws li voids lossis cov khoom tsis sib xws. Yog li ntawd, optimizing kev ua tsis tau yog qhov tseem ceeb rau kev ua tiav cov yam ntxwv xav tau kev kho tshuab thaum tswj cov tshuaj tiv thaiv.
Kev laus thiab Degradation Mechanisms
Kev sib raug zoo ntawm cov khoom siv kho tshuab ntawm PPH fittings thiab cov txheej txheem tshuaj lom neeg kuj suav nrog kev nkag siab txog kev laus thiab degradation mechanisms. Thaum lub sij hawm, ib puag ncig yam xws li UV hluav taws xob, kub hloov pauv, thiab tshuaj lom neeg tuaj yeem ua rau degradation, cuam tshuam cov khoom siv zog thiab elasticity. Kev saib xyuas thiab kev saib xyuas tsis tu ncua tuaj yeem pab txo cov teebmeem no, kom ntseeg tau tias PPH fittings tswj lawv cov neeg kho tshuab kev ncaj ncees thoob plaws hauv lawv lub neej ua haujlwm. Cov neeg tsim khoom feem ntau ua cov kev tshawb fawb ntev kom nkag siab tias cov txheej txheem tshuaj sib txawv ua rau muaj kev laus li cas, tso cai rau kev txhim kho cov khoom tsim thiab cov qauv tsim uas txhim khu kev ruaj ntseg.
Xaus
Hauv kev xaus, cov khoom siv kho tshuab ntawm PPH fittings yog sib txuas nrog cov txheej txheem tshuaj lom neeg uas lawv tau dhau los thaum tsim khoom thiab hauv lawv qhov chaw ua haujlwm. Los ntawm kev nkag siab txog kev sib raug zoo ntawm cov qauv tshuaj, raug rau cov tshuaj, kev ua haujlwm, thiab cov txheej txheem kev laus, cov tuam txhab tuaj yeem txhim kho qhov kev ua tau zoo ntawm PPH fittings rau ntau yam kev siv. Qhov kev paub no tsis tsuas yog ua kom muaj kev ntseeg siab thiab kev ua neej ntev ntawm cov khoom siv no tab sis kuj tseem txhim kho lawv cov txiaj ntsig tag nrho hauv kev lag luam. Raws li qhov kev thov rau cov ntaub ntawv qib siab txuas ntxiv mus ntxiv, kev tshawb fawb thiab kev txhim kho txuas ntxiv yuav ua rau pom kev sib txuas ntawm cov khoom siv tshuab thiab cov txheej txheem tshuaj, ua rau kev hloov kho tshiab hauv PPH haum thev naus laus zis.
