Thaum xaiv PtFE tubing rau siab - qhov kub thiab txias ib puag ncig, koj tsis ntsib qhov yooj yim "nws puas tuaj yeem siv tau?" lo lus nug, tab sis yog qhov kev txiav txim siab zoo tshaj plaws txog kev ua haujlwm ntev txog - lub sij hawm thermal stability, mechanical property retention, and system security boundaries. Thaum PTFE cov ntaub ntawv muaj feem ntau lees txais kev khiav hauj lwm ntau ntawm -200℃rau +260℃, cov tswv yim siab -kub siv tau nthuav qhia ntau yam kev sib tw-260℃yog qhov dej ntws. Tshaj li 260 degree, kev ua siab ntev ntev thiab kev laus ua haujlwm ntev sib txawv, thiab qhov muaj siab thiab nruab nrab cuam tshuam nws tus cwj pwm. Yog li ntawd, kev xaiv kom raug yuav tsum yog cov txheej txheem ntsuam xyuas, tsis yog xaiv qhov siab tshaj plaws nominal tus nqi.
Txhawm rau ua kom muaj kev ntseeg siab, ob qhov kev xav tsis zoo yuav tsum tau kov yeej: ua ntej, qhov kev xav tias "tag nrho cov PTFE tubing coj zoo ib yam nyob rau hauv nws cov nominal kub ntau yam"; thiab thib ob, tsis quav ntsej txog "synergistic nyhuv ntawm qhov kub thiab txias nrog lub siab thiab qhov nruab nrab." Kev xaiv tiag tiag yuav tsum yog raws li plaub- qhov sib txawv ntawm tus ntoo khaub lig- ntsuas kub, sijhawm, kev ntxhov siab, thiab qhov nruab nrab. Ua ntej, koj yuav tsum qhia meej meej qhov tseeb qhov ntsuas kub hauv koj daim ntawv thov: nws puas yog qhov txuas mus tas li 260 degree, lossis puas muaj lub sijhawm ntev tshaj li 300 degree? Cov kav dej raug rau qhov kub thiab txias ze 260℃rau lub sij hawm ntev yuav raug thermal aging, uas ua rau qeeb qeeb hauv toughness. Qhov thib ob, kev khiav hauj lwm siab yog qhov tseem ceeb: qhov kub thiab txias txo qhov kev tawm tsam ntawm PTFE, thiab nyob rau hauv siab, cov yeeb nkab phab ntsa yuav maj mam deform (txias ntws), ua rau lub foob tsis ua hauj lwm hauv compression fittings. Thaum kawg, cov khoom ntawm qhov siab - kub nruab nrab yog qhov txiav txim siab: ntau cov tshuaj inert nyob rau hauv chav tsev kub (xws li tej yam organic solvents los yog muaj zog oxidants) muaj ntau yam kev ua si nyob rau hauv high kub, muaj peev xwm ua rau nkag mus, o, los yog kev nyuaj siab tawg.
Raws li kev txheeb xyuas saum toj no, koj tuaj yeem tsim cov saw hlau txiav txim siab hauv peb kauj ruam: Ua ntej, lees paub cov khoom tseem ceeb. Rau cov ntawv thov uas yuav tsum tau ntev -lub sij hawm kub siab tshaj 260℃los yog xav tau zoo heev creep kuj, ua ntej sau thiab hloov PTFE kav, xws li cov iav fiber ntau ntxiv los yog carbon hmoov, uas ho txhim kho qhov seem stability thiab siab tsis kam ntawm kub kub. Thib ob, suav cov ntsiab lus tseem ceeb. Kev ruaj ntseg phab ntsa thickness yuav tsum tau muab xam thiab nce raws li kev khiav hauj lwm siab thiab kub los them rau lub zog degradation ntawm kub kub; ib txhij, tsim cov qauv kev txhawb nqa (xws li armor lossis kev txhawb nqa) kom txo tau kev ntxhov siab ntawm cov yeeb nkab kub. Thib peb, txheeb xyuas cov khoom muaj peev xwm. Thov cov neeg muab khoom siv los muab cov ntaub ntawv ntsuas kev kub ntxhov ntev ntev thiab siab - qhov ntsuas kub siab ntsuas nkhaus rau cov khoom lag luam ntawm qhov kub siab, tsis yog tsuas yog xa mus rau cov ntaub ntawv kub hauv chav. Ib tus kws tshaj lij kev lag luam yuav tsum muaj peev xwm piav qhia txog hom kev ua tsis tiav thiab kev nyab xeeb ntawm lawv cov khoom ntawm qhov kub thiab txias.
Yog li ntawd, xaiv PtFE Tubing rau siab - qhov kub thiab txias ib puag ncig yog qhov tseem ceeb xaiv cov ntaub ntawv - tsav kev sib koom tes. Nws xav kom cov neeg muag khoom muab tsis yog cov khoom lag luam nkaus xwb tab sis kuj muaj kev kwv yees kev ua tau zoo thiab kev daws teeb meem nyob rau hauv thermal stress. Peb pom zoo kom koj muab peb cov kev ntsuas kub tshwj xeeb, lub voj voog siab, thiab cov ntaub ntawv xov xwm. Peb pab neeg ua haujlwm engineering tuaj yeem muab cov thermos dawb rau koj- kev ntsuas kev sib txuas ntawm cov tshuab sib txuas, nrog rau cov lus qhia rau kev hloov kho thiab kho cov phab ntsa tuab kom ntseeg tau tias qhov ruaj khov ntawm koj qhov siab - qhov kub thiab txias thoob plaws hauv nws lub neej.
