Zoo sib xws nrog txhua yam ntawm nplooj ntawv no, qhov no yog ib qho piv txwv ntawm Ntxiv polymerization . Ib ntxiv cov tshuaj tiv thaiv yog ib qho uas ob lossis ntau lub molecules koom ua ke los muab ib yam khoom.
Kev tsim khoom.
| Kub: | txog 60 ° C |
|---|---|
| Siab: | qis - ob peb qhov cua |
| Catalyst: | Ziegler-Natta catalysts lossis lwm cov hlau sib txuas |
Hauv qhov no, dab tsi ntxiv polymerization GCSE?
Polymerization . Ntxiv cov polymers yog tsim los ntawm kev sib koom ua ke ntawm ntau cov monomers uas muaj C = C bonds. Ib daim ntawv cog lus hauv txhua C = C tawg thiab tsim ib daim ntawv cog lus nrog cov monomer uas nyob ib sab. Lub polymer tsim muaj tsuas yog carbon carbon ib daim ntawv cog lus. Ntau polymers tuaj yeem ua los ntawm ntxiv ntawm alkene monomers.
Tsis tas li ntawd, muaj pes tsawg hom monomers ntxiv rau polymerization? Qhov ob daim ntawv cog lus, txawm li cas los xij, yog qhov tseem ceeb uas tso cai rau cov no cov monomers tsim kom ntev polymer chains. Tam sim no, cia peb saib lwm plaub cov monomers . (Faj seeb: peb muaj ob txawv pab pawg ntawm cov monomers vim peb muaj ob txawv Cov tshuaj tiv thaiv polymerization.) Cov plaub no cov monomers muaj qhov peb hu ua pawg ua haujlwm.
Yog li ntawd, vim li cas qhov no yog ib qho ntxiv polymerization?
Me me unsaturated ethene monomers koom nrog los ntawm kev qhib ntawm ob daim ntawv cog lus tso cai rau lawv los koom ua ib qho kev sib txuas ntev carbon. Polymers ua li no hu ua ntxiv polymers. Muab cov qauv ntawm lub monomer tus qauv qauv ntawm lub ntxiv polymer tuaj yeem kos.
Ob hom polymerization yog dab tsi?
Muaj ob yooj yim hom ntawm polymerization , chain-reaction (los yog ntxiv) thiab kauj ruam-reaction (los yog condensation) polymerization . Ib qho ntawm feem ntau hom ntawm polymer cov tshuaj tiv thaiv yog chain-reaction (ntxiv) polymerization . Hom ntawm polymerization yog peb kauj ruam txheej txheem uas muaj ob cov koom haum tshuaj.

ICS thaj chaw ua haujlwm twg teeb tsa cov phiaj xwm phiaj xwm phiaj xwm thiab ua ntej thiab muaj lub luag haujlwm tag nrho rau qhov xwm txheej?
Cov lus txib xwm txheej yog lub luag haujlwm rau kev teeb tsa lub hom phiaj xwm txheej, cov tswv yim thiab qhov tseem ceeb. Nws kuj muaj lub luag haujlwm tag nrho rau qhov xwm txheej
Dab tsi yog cov ntsiab lus tseem ceeb ntawm qhov phiaj xwm phiaj xwm xwm txheej?
Lub Hom Phiaj Xwm Txheej Xwm Txheej yog dab tsi? Cov hom phiaj xwm txheej tshwm sim (qhov twg cov lus teb xav tau thaum kawg ntawm cov lus teb) Lub sijhawm ua haujlwm lub hom phiaj (cov cheeb tsam loj uas yuav tsum tau hais hauv lub sijhawm ua haujlwm tau teev tseg kom ua tiav cov hom phiaj lossis cov hom phiaj tswj hwm) Cov tswv yim teb (qhov tseem ceeb thiab txoj hauv kev kom ua tiav hom phiaj)
Dab tsi yog qhov txawv ntawm qhov tsis muaj xwm txheej thiab cov xwm txheej sentinel?
Cov xwm txheej Sentinel tau txhais tias yog 'qhov tshwm sim tsis tau xav txog uas cuam tshuam txog kev tuag lossis kev puas tsuaj loj ntawm lub cev lossis kev puas siab puas ntsws, lossis kev pheej hmoo ntawm qhov ntawd.' Lub NQF's Never Events kuj tseem suav tias yog cov xwm txheej xa mus los ntawm Pawg Neeg Sib Koom Tes. Lub Koom Haum Koom Tes ua haujlwm tau ua tiav ntawm qhov kev tshuaj xyuas hauv paus tom qab kev tshwm sim sentinel
Dab tsi yog cov cuab yeej lossis cov txheej txheem siv los hloov cov ntaub ntawv kev ua haujlwm rau hauv cov ntaub ntawv kev ua haujlwm hauv cov txheej txheem tswj Scope?
Variance Analysis yog ib qho cuab yeej & Cov txheej txheem ntawm Kev Tswj Scope Txheej Txheem thiab Kev Ntsuas Kev Ua Haujlwm Ua Haujlwm (WPM) yog qhov tso tawm ntawm cov txheej txheem no
Dab tsi yog qhov xwm txheej thiab qhov xwm txheej uas koj yuav tsum tau tshaj tawm rau FAA?
Cov lus teb luv luv yog tias "kev sib tsoo" thiab "qhov xwm txheej hnyav" yuav tsum raug qhia rau NTSB, tab sis qhov xwm txheej tsis loj tsis tas yuav tsum tau tshaj tawm, raws li 49 CFR 830.2 thiab 830.5. Tsis muaj xwm txheej lossis qhov xwm txheej loj raug tshaj tawm rau FAA tshwj tsis yog FAA thov cov ntaub ntawv raws li ib feem ntawm kev tshawb nrhiav
