Rau cov chaw tsim khoom PVC, kev nrhiav cov khoom ruaj khov uas sib npaug kev ua tau zoo, kev ua haujlwm tau zoo, thiab kev ruaj khov tau ntev los ua ib qho kev tshawb nrhiav nyuaj. Cov khoom PVC ruaj khov xws li cov thav qhov rai, cov vaj huam sib luag qhov rooj, thiab cov qauv tsim kho xav tau kev tiv taus cua sov tas li, qhov chaw du, thiab ua raws li cov cai ib puag ncig nruj - tag nrho thaum ua kom cov khoom tsim tau zoo thiab tsis muaj qhov tsis zoo. Nkag muscov tshuaj calcium-zinc (Ca-Zn) uas ua rau cov tshuaj stabilizers ntau ntxiv: ib qho kev daws teeb meem hloov pauv kev ua si uas daws cov teeb meem tseem ceeb hauv kev lag luam thaum qhib cov cib fim tshiab rau kev tsim khoom PVC zoo.
Cov Txuj Ci Tom Qab Cov Granules: Vim Li Cas Daim Ntawv Tseem Ceeb
Tsis zoo licov hmoov stabilizersCov khoom uas tsis huv, nyuaj rau ntsuas, lossis yooj yim sib sau ua ke, cov khoom Ca-Zn stabilizers tau tsim los kom raug. Lawv qhov loj me sib npaug ua kom yooj yim sib xyaw rau hauv PVC cov sib xyaw, tshem tawm qhov teeb meem ntawm kev sib kis tsis sib xws - qhov ua rau muaj kev tsis sib xws ntawm cov khoom. Tab sis cov txiaj ntsig kev siv tshuab mus dhau qhov kev tuav:
• Kev Ruaj Ntseg Kub Zoo Tshaj Plaws:Tseem ceeb rau kev ua cov PVC tawv (piv txwv li, extrusion, txhaj tshuaj molding), cov stabilizers no tiv taus kev puas tsuaj thermal thaum lub sijhawm tsim khoom kub siab, tiv thaiv kev hloov pauv thiab kev tsis muaj zog ntawm cov qauv hauv cov khoom kawg.
• Kev Nqus Tau Zoo Dua:Cov duab granular txo qhov kev sib txhuam ntawm cov khoom me me ntawm PVC resin, txhim kho kev yaj thaum lub sijhawm ua tiav. Qhov no tsis yog tsuas yog ua kom cov voj voog ntau lawm sai dua xwb tab sis kuj ua rau cov nplaim du ntawm cov profiles thiab panels - tsis muaj cov npoo ntxhib lossis cov qhov tsis zoo ntawm qhov chaw.
• Lubrication ua ke:Ib qho txiaj ntsig tseem ceeb rau cov ntaub ntawv siv hauv kev tsim kho, cov khoom siv roj nplua nyeem uas muaj cov stabilizers ua rau kev tsim khoom yooj yim dua, ua rau cov khoom siv PVC nyuaj tsis lo rau cov tshuab.
Kev Siv Tau Ntau Yam: Txij Li Kev Tsim Kho Mus Txog Dhau Mus
Cov khoom siv granular Ca-Zn stabilizers ci ntsa iab tshaj plaws hauv kev tsim khoom PVC ruaj khov, qhov twg lawv cov kev ua tau zoo cuam tshuam ncaj qha rau cov khoom ruaj khov thiab kev zoo nkauj. Piv txwv li, cov thav qhov rai thiab cov vaj huam sib luag qhov rooj vam khom lawv qhov kev ruaj khov ntawm cua sov kom tiv taus huab cua hnyav dhau sijhawm, thaum cov qauv tsim kho tau txais txiaj ntsig los ntawm kev sib kis tas li kom tswj tau qhov ruaj khov ntawm cov qauv. Tab sis lawv qhov kev hloov pauv tsis xaus rau ntawd - lawv kuj zoo tagnrho rau cov kav dej PVC, cov khoom siv, thiab txawm tias cov khoom dai kom zoo nkauj, hloov kho rau ntau txoj kev ua tiav yam tsis muaj kev cuam tshuam zoo.
Rau cov chaw tsim khoom uas tsom mus rau kev lag luam vaj tse ntsuab, cov stabilizers no yog qhov yeej ua raws li txoj cai: tsis zoo li lwm cov khoom siv hlau hnyav (piv txwv li, cov stabilizers ua los ntawm txhuas lossis cadmium), lawv tsis ua rau ib puag ncig puas tsuaj, tsis muaj tshuaj lom, thiab ua tau raws li cov qauv ib puag ncig thoob ntiaj teb (xws li EU REACH thiab US EPA cov cai). Qhov no ua rau lawv yog qhov kev xaiv zoo rau cov hom lag luam uas muab qhov tseem ceeb rau kev ruaj khov yam tsis muaj kev txo qis kev ua tau zoo.
Kev daws teeb meem cov neeg tsim khoom'Cov Teeb Meem Mob Tshaj Plaws
Cov chaw tsim khoom PVC ntsib teeb meem tshwj xeeb uas tuaj yeem ua rau kev tsim khoom tsis zoo thiab qhov zoo ntawm cov khoom. Nov yog li cas cov tshuaj Ca-Zn stabilizers daws cov teeb meem tseem ceeb tshaj plaws:
▼ Qhov Mob 1: Kev tawg tsis zoo ua rau muaj qhov tsis zoo
Cov tshuaj stabilizers uas tsis sib npaug ua rau muaj cov pob kub, xim tsis sib xws, thiab cov pob tawg hauv cov khoom PVC—ua rau cov tuam txhab tsim khoom siv sijhawm thiab nyiaj txiag hauv kev rov ua dua. Kev daws teeb meem: Hom ntawv granular ua kom muaj kev sib xyaw nrog PVC resin, txawm tias nyob rau hauv cov extruders ceev ceev. Cov neeg tsim khoom tsis tas yuav nqis peev rau cov khoom siv sib xyaw ntxiv lossis ncua sijhawm ua tiav; lubcov tshuaj stabilizerfaib tawm tas li, txiav cov kev puas tsuaj tseem ceeb.
▼ Qhov Mob 2: Kev Ua Haujlwm Tsis Zoo Vim Yog Kev Nqus Dej Tsis Zoo
Cov tshuaj PVC uas nplaum ua rau qeeb qeeb ntawm kev tsim khoom, ua rau lub tshuab hnav, thiab ua rau cov khoom loj tsis sib xws. Kev daws teeb meem: Cov tshuaj Ca-Zn stabilizers ua rau cov dej yaj los ntawm kev txo cov kev sib txhuam sab hauv. Qhov no ua rau cov kab ceev dua, lub sijhawm luv dua, thiab lub sijhawm tsis ua haujlwm rau kev ntxuav tshuab tsawg dua - ua rau tag nrho cov khoom tsim tau txog li 15% (raws li cov qauv kev lag luam).
▼ Qhov Mob 3: Kev Pheej Hmoo ntawm Kev Ua Raws Cai Ib puag ncig
Cov tshuaj stabilizers uas ua los ntawm cov hlau hnyav ntsib kev txwv ntau zuj zus thoob ntiaj teb, ua rau cov chaw tsim khoom muaj kev phom sij rau kev nplua thiab kev puas tsuaj rau lub koob npe nrov. Kev daws teeb meem: Yog tsis muaj cov hlau hnyav uas ua rau muaj kev phom sij, cov tshuaj stabilizers Ca-Zn granular tshem tawm cov kev pheej hmoo ntawm kev puas tsuaj rau ib puag ncig. Lawv yooj yim rau kev sib xyaw rau hauv cov kab ntau lawm uas twb muaj lawm (tsis tas yuav hloov kho cov khoom siv kim) thiab pab cov hom lag luam ua tiav cov hom phiaj kev ruaj khov thaum ua raws li txoj cai.
▼ Qhov Mob 4: Qhov Nyuaj Hauv Kev Ntsuas Kom Tseeb
Cov tshuaj stabilizer hmoov nyuaj rau ntsuas kom raug, ua rau siv ntau dhau (nqi nce ntxiv) lossis siv tsis txaus (ua rau tsis ruaj khov). Kev daws teeb meem: Cov khoom me me yooj yim rau kev noj nrog cov khoom siv pub mis txheem, ua kom muaj kev tswj hwm meej ntawm cov qib ntxiv (feem ntau 3-5 PHR). Qhov no tsis yog tsuas yog txo cov khoom pov tseg xwb tab sis kuj tseem tswj tau cov khoom zoo ib yam tom qab ib zaug.
Vim li cas Granular Ca-Zn Stabilizers Yog Yav Tom Ntej ntawm PVC
Hauv kev ua lag luam uas kev ua haujlwm tau zoo, kev ruaj khov, thiab qhov zoo tsis yog qhov sib tham tau, cov tshuaj calcium-zinc complex stabilizers ua tau txhua yam. Lawv daws cov teeb meem kev tsim khoom uas tau ntev los lawm, hloov kho rau ntau yam kev siv PVC ruaj khov, thiab ua raws li kev lag luam hloov mus rau kev tsim khoom uas tsis ua rau ib puag ncig puas tsuaj. Rau cov neeg tsim khoom uas xav kom sib tw, cov thev naus laus zis no tsis yog kev hloov kho tshiab xwb - nws yog qhov tsim nyog.
Txawm koj tab tom tsim cov qauv tsim kho, cov thav duab qhov rai, lossis cov khoom siv PVC, cov khoom siv Ca-Zn stabilizers muab kev ntseeg siab thiab kev ua tau zoo uas xav tau los sawv tawm hauv kev ua lag luam uas muaj neeg coob coob. Thaum cov kev cai ib puag ncig nruj dua thiab cov neeg siv khoom xav tau cov khoom lag luam ruaj khov loj hlob, cov khoom siv stabilizers no yuav txuas ntxiv mus ua qhov kev xaiv zoo tshaj plaws rau kev xav txog yav tom ntej.Cov chaw tsim khoom PVC.
