Xav txog tias koj yog lub tuam txhab tsim tsheb tsim khoom tawv tawv, muab koj lub siab thiab tus ntsuj plig los tsim cov khoom zoo meej. Koj tau xaivkua barium - zinc stabilizers, ib qho kev xaiv zoo li txhim khu kev qha, los tiv thaiv koj cov PVC - raws li tawv tawv thaum tsim khoom. Tab sis tom qab ntawd, lub sijhawm txaus ntshai tuaj txog - koj cov khoom tiav ntsib qhov kev sim siab kawg: kev sim ntsuas kub ntawm 120 - degree Celsius. Thiab rau koj dismay, yellowing rears nws lub taub hau dab tuag. Dab tsi hauv ntiaj teb tab tom mus? Puas yog qhov zoo ntawm phosphite nyob rau hauv koj cov kua barium - zinc stabilizers, los yog puas muaj lwm yam tsis ncaj ncees lawm culprits ntawm kev ua si? Cia peb pib ntawm tus neeg tshawb nrhiav - style taug kev txhawm rau txhawm rau cov ntaub ntawv muaj yeeb yuj!
Lub luag haujlwm ntawm Liquid Barium - Zinc Stabilizers hauv ArtificialTawv
Ua ntej peb dhia mus rau hauv qhov paub tsis meej ntawm yellowing, cia peb rov qab sai sai lub luag haujlwm ntawm cov kua barium - zinc stabilizers hauv cov tawv tawv tsim. Cov stabilizers no zoo li cov neeg saib xyuas ntawm koj lub PVC, ua haujlwm hnyav los tiv thaiv nws los ntawm kev kub ntxhov, lub teeb, thiab oxygen. Lawv neutralize hydrochloric acid tso tawm thaum lub sij hawm PVC degradation, hloov chlorine atoms tsis ruaj tsis khov, thiab muaj kev tiv thaiv antioxidant. Nyob rau hauv lub ntiaj teb tsheb, qhov twg cov tawv nqaij yog raug rau txhua yam ntawm ib puag ncig tej yam kev mob, los ntawm scorching tshav ntuj mus rau huab cua kub hloov nyob rau hauv lub tsheb, cov stabilizers yog ib qho tseem ceeb rau kev ua kom lub neej ntev thiab zoo ntawm cov khoom.
Cov Lus Nug: Phosphite Zoo hauv Cov Kua Dej Barium - Zinc Stabilizers
Tam sim no, cia peb tig mus rau qhov kev xav phem tshaj plaws - phosphite hauv kua barium - zinc stabilizers. Phosphite yog ib feem tseem ceeb uas ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm tag nrho ntawm lub zog stabilizer. High-zoo phosphite muaj cov txiaj ntsig zoo antioxidant, uas txhais tau hais tias nws tuaj yeem tiv thaiv oxidative degradation uas feem ntau ua rau yellowing.
Xav tias phosphite yog superhero, swooping nyob rau hauv kom txuag lub hnub thaum dawb radicals (cov neeg phem hauv zaj dab neeg no) sim tua koj cov tawv nqaij. Thaum phosphite yog subpar zoo, nws yuav tsis tuaj yeem ua nws txoj haujlwm zoo. Tej zaum nws yuav tsis tuaj yeem cuam tshuam tag nrho cov dawb radicals tsim thaum lub sij hawm ntsuas kub, tso cai rau lawv ua kev puas tsuaj rau PVC qauv thiab ua rau yellowing.
Piv txwv li, yog tias cov phosphite nyob rau hauv koj cov kua barium - zinc stabilizer tau ua tsis zoo los yog tau kis kab mob thaum lub sij hawm ntau lawm, nws yuav poob nws cov antioxidant potency. Qhov no yuav ua rau koj cov tawv nqaij tawv tsis zoo rau qhov kub siab - qhov kub thiab txias, ua rau qhov tsis xav tau daj daj.
Lwm Yam Ua TauCov neeg ua txhaum
Tab sis tos, phosphite tsis yog tib tus uas tuaj yeem nyob tom qab qhov tsis paub daj daj no. Muaj ob peb lwm yam uas yuav ua rau muaj teeb meem.
Kub thiabSijhawm
Kev ntsuas kub ntawm nws tus kheej yog qhov nyuaj. Kev sib xyaw ua ke ntawm 120 - degree Celsius tshav kub thiab lub sijhawm ntawm kev sim tuaj yeem ua rau muaj kev ntxhov siab ntau rau ntawm cov tawv nqaij. Yog tias qhov ntsuas kub tsis sib npaug thaum lub sijhawm kuaj lossis yog tias cov tawv nqaij raug tshav kub ntev dua li qhov tsim nyog, nws tuaj yeem ua rau muaj qhov yellowing. Nws zoo li tso lub ncuav mog qab zib rau hauv qhov cub ntev heev - tej yam pib mus tsis ncaj ncees lawm, thiab xim hloov.
Nyob ntawmCov impurities
Txawm tias me me ntawm impurities nyob rau hauv PVC resin los yog lwm yam additives siv nyob rau hauv cov khoom siv tawv tawv yuav muaj kev cuam tshuam loj. Cov impurities no tuaj yeem hnov mob nrog cov stabilizers lossis PVC hauv qhov kub thiab txias, ua rau muaj tshuaj lom neeg uas ua rau yellowing. Nws yog zoo li ib tug zais saboteur, ntsiag to ua chaos los ntawm sab hauv.
Kev sib haum xeebTeeb meem
Cov kua barium - zinc stabilizer yuav tsum ua hauj lwm nyob rau hauv kev sib raug zoo nrog rau lwm yam khoom nyob rau hauv cov khoom siv tawv, xws li plasticizers thiab pigments. Yog tias muaj teeb meem kev sib raug zoo ntawm cov khoom siv no, nws tuaj yeem cuam tshuam cov stabilizer kev ua tau zoo thiab ua rau yellowing. Nws yog me ntsis zoo li ib pab pawg tsis sib haum - yog tias cov tswv cuab tsis ua haujlwm zoo ua ke, lub suab paj nruag tawm.
Kev daws qhovTsis paub
Yog li, koj yuav ua li cas daws qhov tsis paub yellowing no thiab xyuas kom koj cov tawv tawv dhau los ntawm kev ntsuas kub nrog cov xim ya?
Ua ntej, nws yog ib qho tseem ceeb heev rau qhov zoo tshaj plaws - zoo kua barium - zinc stabilizers los ntawm ib tug txhim khu kev qha tsum. Xyuas kom tseeb tias cov phosphite nyob rau hauv lub stabilizer yog cov saum toj kawg nkaus - tsis zoo thiab tau raug kuaj kom zoo rau nws cov antioxidant zog.
Tom ntej no, ua tib zoo tshuaj xyuas thiab txhim kho koj cov txheej txheem ntau lawm. Xyuas kom meej tias qhov ntsuas kub thiab lub sij hawm thaum lub sij hawm ntsuas kub yog tswj kom meej, thiab tias tag nrho cov khoom siv ua haujlwm zoo los xyuas kom meej tias qhov hluav taws xob faib tawm.
Tsis tas li ntawd, xyuam xim rau qhov zoo ntawm cov khoom siv raw uas koj siv. Ua tib zoo sim cov PVC resin thiab lwm yam khoom ntxiv rau impurities thiab xyuas kom tseeb tias lawv tau sib xws nrog cov stabilizer system.
Los ntawm kev ua cov kauj ruam no, koj tuaj yeem tawg qhov teeb meem ntawm yellowing thiab tsim cov tawv tawv uas tsis tsuas yog zoo nkaus li zoo, tab sis kuj sawv cev rau cov kev ntsuas kub hnyav tshaj plaws, ua rau koj cov neeg siv khoom siv tsheb zoo siab thiab koj cov khoom sib tham hauv nroog.
Nyob rau hauv lub ntiaj teb no ntawm cov khoom siv tawv tawv, txhua qhov tsis paub meej muaj kev daws teeb meem. Nws yog txhua yam hais txog kev ua tus paub txog kev tshawb nrhiav, txheeb xyuas cov neeg raug tsim txom, thiab ua cov kauj ruam zoo los daws qhov teeb meem. Yog li, npaj, thiab cia cov khoom siv tawv tawv zoo saib lawv qhov zoo tshaj plaws!
