Kev ntsuam xyuas ntawm cov khoom siv yas yuav suav nrog kev txiav txim ntawm cov khoom kub (qhov kub nyhiab), cov khoom siv hluav taws xob los ntawm ntau lub thermal thiab hluav taws xob, hluav taws xob kev soj ntsuam thiab cov hluav taws xob ntxiv, thiab kev tshuaj ntsuam xyuas. Cov cuab yeej tuav tseg tom qab kis tau tus kab mob mus ntev (huab cua kub laus), dej, ultraviolet light, txias, thiab lwm yam sab nraud.
Cov kev soj ntsuam los ntawm UL muaj xws li:
Cov ntaub ntawv siv rau hauv cov cheeb tsam tshwj xeeb yog tshawb xyuas kev siv cov khoom siv thaum xaus uas tsim nyog rau kev tuav tseg ntawm cov khoom tom qab raug qee yam hauj lwm tseem ceeb thiab / los yog ib puag ncig. Qhov no suav nrog ntau hom ultraviolet (UV) hluav taws xob.
Xim concentration (QMQS2)
Thaum twg qhov chaw tsim khoom tsim tshuaj yuav tsum tau muab cov khoom siv rau xim muag, cov khoom muag pom zoo yuav tsum nres ntau, ntxuav cov tshuab, thiab npaj mus nrog ib qho chaw tshwj xeeb rau kev tsim tawm ntawm cov kev cai xim no. Qhov no yog lub sij hawm siv thiab siv tus txheej txheem uas feem ntau yog thaws tus nqi ntawm qhov kev txiav txim. Tsis tas li ntawd, Cov chaw muag khoom uas tau lees paub yuav tsum xav tau yam tsawg kawg nkaus ntshe tshwj tsis yog tias qhov kev txiav txim siab yog ua kom zoo dua qub.
Cov xim ntawm cov xim (QMQS2) muaj cov khoom lag luam cov khoom lag luam uas tau ntsib nrog rau cov teeb meem no kev xaiv kom tau qhov tsim nyog npaum li cas ntawm cov ntaubntawv povthawj tshwjxeeb uas zoo lawm thaum tseem ua kom muaj xim yeem Zoo rau kev siv nrog Cov Ntawv Pov Thawj. Los ntawm qhuav blending ob cov ntaub ntawv tsis muaj ntau tshaj tawm tshaj qhov tshaj tawm-down piv, cov khoom kawg-tuam ntxhab tau tsim qhov kev sib cog lus, uas yog feem ntau raug ntau tshaj qhov kev txiav txim siab ntawm ib qho kev cai Cov Nyiaj Txiag.
Kev lees paub ntawm cov xim nqaij nyuj siv rau kev siv nrog vertically rated Cov ntaub ntawv qhia qis los ntawm tus kheej yog qhov tshwj xeeb thiab yuav tsum tau xa cov ntawv tso cai ntawm cov ntawv xeem. Cov kev kuaj uas muaj cov xim ntawm cov xim uas muaj peev xwm ua rau hauv cov ntaub ntawv qhia tias yuav tsum ua kom pom tseeb tias kev siv cov xim tsis zoo yuav tsis cuam tshuam qhov ntsuas qhov ntsuas ntawm Recognized base resin. Kev Lees Paub ntawm cov xim nqaij tawv yuav tsum xa thiab kuaj rau txhua daim ntawv txhais tau tias cov ntaub ntawv uas tsis xam nrog cov ntaub ntawv.
Zoo tib yam, Kev Lees Paub siv nrog HB Cov Npaj Luv Cov Nqaij Ntxawg los yuav siv cov ntawv tso tawm ntawm cov qauv kev ntsuam xyuas ntawm cov xim nqaij tawv kom mus rau hauv lub HB-rated base resin rau kev kuaj xyuas. Yog tias qhov kev ntsuas no tsis cuam tshuam qhov kev ntsuam xyuas ntawm HB liam ntawm Cov Txiaj Ntsig Zoo Tshaj Plaws, Cov xim tshiab pom tau zoo tshaj plaws uas muaj feem xyuam siv nws cov ntaub ntawv siv hauv HB-nqi los ntawm lub hom phiaj ntawm hom.
Cheebtsam Taw Qhia (QMLJ2)
Lub tuam txhab muaj kev sib txuas ntawm cov khoom siv feem ntau yuav yog cov khoom zoo nkauj los ntawm cov khoom lag luam coj los ua thiab ua rau cov kev tsim tawm los ntawm kev tawm tswv yim ntxiv rau cov khoom tshiab. Cov ntaub ntawv tshiab no tau raug kuaj thiab luam tawm hauv qeb ntawm cov khoom tivthaiv hauv plastics (QMFZ2). Cov kev tivthaiv kabmob (QMLJ2) tau pom zoo rau Kev Lees Paub ntawm cov khoom siv ntxiv rau cov khoom uas tau muab coj los siv nrog cov Recognized zoo huv si los tsim tsim cov ntaub ntawv tshiab uas tau txais kev lees paub.
Q Qixi QMLJ2 kuj tau tso cai rau cov ntaub ntawv los ntawm cov ntaub ntawv uas tau muab xa tuaj ncaj qha mus rau qhov chaw kawg ntawm cov khoom muag. Kev paub cov ntsiab lus zoo tau muab xa ncaj nraim rau lub khw thiab. Ua ntej moulding, pob khoom thiab pob yog qhuav-blended ntawm tus piv txwv-down-down los ntawm lub khw muag khoom pov thawj. Rau cov txheej txheem no, cov chaw tsim tsheb yuav tsum raug lees paub raws li cov ntaub ntawm cov ntaub ntawv, Cov khoom ntuas tau pom zoo (QMMY2).
Txoj kev ntawm qhov muab lub hauv paus cob qhia muab cov khoom lag luam khoom kawg rau lub tuam txhab ua khoom loj thiab kev xa khoom tuaj ntawm lub hauv paus. Qhov kev paub tau zoo tshaj plaws tuaj yeem raug yuam kom xa thiab xa raws li cov sijhawm ua haujlwm. Hom no kuj muaj cov khoom lag luam nrog lub peev xwm ntawm cov khoom loj zus ntawm lub hauv paus puag es tsis yog cov kev cai yuam kev.
Hauv Tshaj Tawm Kev Tshaj Tawm rau lub tswv yim zoo, Lub Pob Ntseg Zoo Tshaj Tawm, Cov ntaub ntawv lees paub lub npe, tus naj npawb cov ntaub ntawv thiab cov qib ntawv muab teev rau hauv Daim Ntawv Pov Thawj. Cov ntaub ntawv tshiab uas tau lees paub txog, cov ntaub ntawv najnpawb thiab cov npe lag luam tseem raug sau tseg.
Los xyuas kom paub tseeb ntawm reproducibility ntawm Recognized concentrate pob, nrhiav kev ntsuas kom pom ntawm infrared spectroscopy (IR), thermogravinetry (TGA), thiab kev soj ntsuam sib txawv ntawm calorimetry (DSC) nyob rau hauv Cov Kev Ntsuam Xyuas Pob Ntseg Cia rau hauv nws cov cab kuj. Kev soj ntsuam ib ntus nyob rau hauv UL's Cov Kev Pab Taug Qab Tom Qab.
IEC pob Siab Kub (BP)
IEC pob siab kub raws, raws li IEC 695-10-2, qhia tias qhov kub (hauv C) thaum 5 millimeter inch pob ua rau 2-millimeter inch los yog tsawg dua lub tswv yim.
Kev Tawm Sab Nraud
Cov khoom siv tsim nyog rau kev siv sab nraum zoov tau ploj mus los ntawm kev soj ntsuam raws li UL 746C, Polymeric Materials, Siv cov khoom siv hluav taws xob raws li nram no:
1,000 xuab moos ntawm xenon-arc weatherometer txias
Kev siv dej rau xya hnub ntawm 70 degrees C.
Cov khoom siv sim rau kev kub ntxhov, kev ua txhua yam thiab kev dag zog ua ntej thiab tom qab raug mob rau cov mob no. Cov txiaj ntsig ntawm kev sim yuav ua tau rau ib qho ntawm cov txiaj ntsig tau nram qab no:
(f1) - Daim ntawv qhia no txhais tau tias cov khoom tau ntsib UV thiab dej los yog kev tiv thaiv kab mob raws li hu ua UL 746C. Cov khoom siv yog tsim rau kev siv sab nraum zoov nrog rau kev sib raug zoo ntawm ultraviolet light, raug dej, thiab immersion raws li UL 746C.
(f2) - Daim ntawv qhia no txhais tau tias cov khoom siv tau los tsuas tau los yog tau raug kuaj ib ce rau UV lossis dej raug mob los yog kab mob. Cov khoom siv raug rau ib lossis ntau qhov kev ntsuam xyuas hauv qab no: UV, dej raug mob los yog immersion raws li UL 746C, qhov twg qhov kev tsim nyog siv rau sab nraum zoov yog txiav txim los ntawm UL.
Thermal-aging program
Feem ntau cov ntaub ntawv uas tau muaj los ntawm qhov kev pab no tau raug tshawb xyuas txog qee yam tseem ceeb xws li dielectric, tensile thiab cuam tshuam raws li ib qho kev pabcuam long term thermal-aging program ua raws li UL 746B, Polymeric Materials, Kev Ntsuam Xyuas Ntev Ntev .
Qhov kawg ntawm lub neej ntawm txhua yam kev ntsuas hauv qhov kev kawm no yog xav tias yog lub sij hawm thaum tus nqi ntawm qhov khoom tseem ceeb tau poob mus rau 50 feem pua ntawm nws qhov qub (raws li tau txais) tus nqi. Yog tias cov khoom raug tshawb fawb hauv thermal-aging program, qhov ntsuas kub ntawm qhov ntsuas (degrees), nyob hauv cov qib C, tau qhia raws li kev sib piv nrog cov khoom uas muaj kev pabcuam thiab cuam tshuam nrog cov kub saum toj no uas cov khoom yog yuav ua rau me nyuam poob ntxov.
Yog tias cov khoom tsis tau raug tshawb xyuas nyob rau hauv qhov kev pab cuam thermal-ageing, cov neeg muaj lub siab qhia tau raws li cov chav kawm ntawm cov khoom siv. Ib qho kev sib piv ntawm qhov ntsuas kub raws li cov khoom siv hluav taws xob muaj nyob rau hauv UL 746B thiab yog raws li yav dhau los ntawm txoj kev ntsuas thiab kev ua tshuaj.
Ntau tshaj li ib qho kev hnnav plaub ntug yuav tsim nyog rau cov khoom siv nyob ntawm seb yuav tsum tau ua li cas rau tej yam khoom siv rau ib daim ntawv thov. Nyob rau qee rooj plaub, muaj peevxwm dua yog tias tau teev muaj los ntawm qhov khoom siv kawg.
Ntsuas kub ntsuas (degrees) yog qhov ntsuas kub siab tshaj plaws rau ib yam khoom uas ib qho tseem ceeb ntawm cov cuab yeej yuav tsis raug tsis cuam tshuam los ntawm cov tshuaj thermal degradation. Qhov no ncua sij hawm ntawm lub neej tsim nyog ntawm cov khoom hluav taws xob ntsig txog cov khoom siv uas muaj kev lees paub, ua tau zoo los ntawm kev ua haujlwm-txhais kev taw RTI.
Cov pa roj hmab nruab nrog yog ua rau hluav taws xob hluav taws xob tseem ceeb heev.
Mechanical qhov kev sib haum xeeb yog txuam nrog kev ua haujlwm tseem ceeb, kev muaj zog thiab kev yooj yim.
Qhov chaw ua hauj lwm muaj zog nruab nrog tsis muaj kev cuam tshuam nrog kev sib raug zoo ntawm qhov sib zog txhua yam uas ua rau qhov tsis zoo, resilience thiab yooj tsis tseem ceeb.
