Stabilizers tuav peb mus rau tsib feem ntawm ib puas ntawm PVC formulation. Lawv yog ib qho ntawm cov kab me me tshaj plaws hauv kev sib xyaw thiab lawv txiav txim siab, ncaj qha ntau dua li qhov ntom ntom lossis tuab lossis nto tiav, lub teb chaws twg koj tso cai muag rau hauv.
Qhov kev xaiv feem ntau yog nthuav tawm raws li kev ua haujlwm. Nws tsis yog. Nws yog cov lus nug ntawm kev lag luam hnav cov khaub ncaws technical, thiab nws tau txiav txim siab ntawm qhov sib xyaw ua ke ntev ua ntej leej twg xav txog qhov kev txiav txim. Qhov no ua raws li kev sib xyaw ua ke hauv peb phau ntawv qhia rauDab tsi yog qhov tseeb hauv daim ntawv PVC.
Ib daim ntawv ua ntej nthuav dav. Kev tswj hwm txoj haujlwm hloov, thiab lawv txawv ntawm cov khoom qeb thiab los ntawm qhov chaw. Txhua yam hauv qab no yog lub hauv paus rau kev nug cov lus nug zoo dua. Txheeb xyuas txoj haujlwm tam sim no nrog rau cov cai uas cuam tshuam lossis tus kws tshaj lij ua raws cai ua ntej koj xa khoom.
I. Cov Reaction Stabilizers muaj nyob kom nres
PVC tsis tuaj yeem ua tiav yam tsis muaj qhov ruaj khov. Tsis yog "yuav tsum tsis yog". Ua tsis tau.
Los ntawm kwv yees li 180 degrees Celsius lub polymer pib los ua hydrogen chloride. HCl uas tawm los tsis yog passive. Nws catalyses ntxiv dehydrochlorination, yog li cov tshuaj tiv thaiv pub nws tus kheej thiab nrawm. Dab tsi pib raws li ib txoj kab dhau los ua ib qho kev khiav tawm hauv vib nas this ntawm extrusion kub.
Qhov pom tshwm sim yog xim. Raws li chlorine poob lawm, conjugated ob daim ntawv cog lus ua raws li cov saw, thiab cov sequences nqus lub teeb. Cov kab lus luv luv muab daj. Ntev ntev muab xim av, ces dub. Cov txiaj ntsig tsis pom yog qhov phem dua: crosslinking uas rhuav tshem cov yaj, embrittlement uas rhuav tshem qhov ua tiav, thiab cov roj hydrochloric acid uas tawm tsam cov ntsia hlau, lub thoob thiab cov tuag.
Ib tug huv txiav ntug qhia tau hais tias lub yaj yog stabilized txaus rau txoj kab ceev nws khiav ntawm. Discoloration khiav sab hauv los ntawm qhov chaw thaum nws tsis yog.
Lub stabilizer ua haujlwm ntawm peb sab. Nws scavenges HCl uas tsim, hloov cov catalytic hom nrog ib yam dab tsi inert. Nws hloov labile chlorine atoms ntawm cov pob txha polymer, tshem tawm cov chaw uas degradation nyiam pib. Thiab nws cuam tshuam lub voj voog kom qhov kev tshwm sim thawj zaug tsis dhau los ua qhov thib ob.
Txawv stabilizer chemistry ua rau peb txoj haujlwm nrog kev ua haujlwm sib txawv, ntawm tus nqi sib txawv, thiab nrog cov khoom sib txawv.
II. Peb Tsev Neeg, thiab Dab Tsi Txhua Tus Lag Luam Tawm
| Coj | Calcium{0}}zinc | Organotin | |
|---|---|---|---|
| Cov tshuaj sib xyaw | Tribasic lead sulphate, dibasic lead phosphite | Calcium thiab zinc stearates nrog co-stabilizers | Methyltin, octyltin, butyltin |
| Thaum tshav kub kub stability | Tus nqi siab tshaj rau ib chav tsev | Zoo, tab sis nqaim | Zoo heev |
| Qhov tseeb | Opaque. Tsis tuaj yeem tsim daim ntawv ntshiab | Txwv tsis pub | Zoo tshaj hauv chav kawm |
| Sib cuag zaub mov | Tsis muaj | Yog, nrog rau qib zoo | Yog rau methyltin thiab octyltin |
| Nqi | qis tshaj | Siab dua | Siab tshaj |
| Txoj hauj lwm tswj | Txwv nyob rau hauv cov khw loj | Feem ntau txais | Nyob ntawm cov tin compound |
Lead stabilizers yog cov keeb kwm yav dhau los thiab tseem ua tau zoo ntawm txoj haujlwm. Lawv tuav cov xim los ntawm cov keeb kwm kub ntev, lawv ua tau zoo sab nraum zoov, lawv muab PVC zoo hluav taws xob, thiab lawv raug nqi tsawg tshaj plaws. Yog tias qhov kev txiav txim siab yog kev txawj ntse thiab tus nqi tsuas yog lwm qhov sib txawv, cov txhuas yuav yeej hauv cov ntawv thov nruj heev.
Lawv kuj yog tshuaj lom, lawv khaws tag nrho cov khoom lag luam tawm ntawm ntau lub khw loj, thiab lawv tsis tuaj yeem ua daim ntawv pob tshab txhua.
Calcium-zinc systems hloov lawv hauv cov khw. Cov chemistry yog ib pob es tsis yog ib qho ntxiv: calcium stearate thiab zinc stearate ua haujlwm ua ke, txhawb nqa los ntawm co-stabilizers uas suav nrog hydrotalcites, beta-diketones, polyols thiab epoxidised soybean roj. Tau txais pob khoom kom raug thiab Ca-Zn ua haujlwm ze rau cov hlau lead thaum tseem tsis muaj - lom thiab muaj peev xwm ntawm zaub mov- tiv tauj kev pom zoo.
Organotin zaum saum tus nqi ntau thiab khwv tau nws qhov kev pom tseeb tseem ceeb. Daim ntawv pob tshab, zaj duab xis thiab siab -gloss profiles yog organotin thaj chaw vim tias cov hlau lead ua tsis tau thiab Ca-Zn ua nws tsis zoo. Tsev neeg faib kev nyab xeeb, txawm li cas los xij. Methyltin thiab octyltin yog siv rau hauv zaub mov-hu rau daim ntawv thov. Butyltin compounds yog qhov sib txawv kiag li thiab nqa lawv tus kheej txwv.
Xim tuav yog daim npav pom pom rau lub kaw lus stabilizer. Ib daim ntawv uas nyob dawb los ntawm kev ua tiav tau ruaj khov txaus rau cov kab ntawd.
III. Calcium-Zinc muaj ib tug ntxiab ntawm nws tus kheej
Qhov kev xav ntau tshaj plaws yog tias calcium -zinc tsuas yog qhov niaj hnub, muaj kev nyab xeeb dua ntawm cov hlau lead nrog tus nqi siab dua. Qhov kev nyeem ntawv ntawd tsis tiav, thiab qhov sib txawv ntawm ob yog qhov uas ntau lub thawv mus yuam kev.
Zinc ua nws txoj haujlwm ruaj khov los ntawm kev sib pauv nrog labile chlorine ntawm cov saw hlau polymer. Kev sib pauv neutralises qhov chaw labile, uas yog qhov koj xav tau. Cov khoom los ntawm - yog zinc chloride.
Zinc chloride yog ib qho muaj zog Lewis acid, thiab nws catalyses dehydrochlorination deb tshaj li HCl ua ntawm nws tus kheej. Kev lag luam muaj lub npe rau dab tsi hauv qab no. Zinc hlawv.
Vim li cas qhov no tseem ceeb tshaj qhov nws suab
Lead degradation yog nce zuj zus. Koj pom nws tuaj thiab koj muaj sijhawm los kho kab. Zinc kub hnyiab tau tsis muaj kev vam meej. Thaum cov zinc chloride concentration nce mus txog qhov chaw uas nws yuav siv sij hawm dhau, daim ntawv mus los ntawm kev lees txais mus rau dub hauv vib nas this, thiab cov khoom yog seem. Tsis muaj ib nrab rov qab los.
Co-stabilizers muaj los tiv thaiv qhov no. Hydrotalcites thiab beta-diketones cuam tshuam cov zinc chloride ua ntej nws tuaj yeem ua kev puas tsuaj, thiab lub pob tsim kom zoo tuav cov tshuaj tiv thaiv hauv kev txheeb xyuas thoob plaws lub qhov rais ua haujlwm. Lub qhov rais tseem nqaim dua li cov hlau lead, thiab qhov ntawd yog qhov ua tau zoo.
Ib daim ntawv calcium-zinc yog rhiab heev rau txoj kab tswj tau zoo npaum li cas. Kub drift, qeeb qeeb qeeb qeeb, lub sijhawm nyob ntev dua hauv lub thoob, nres - pib khiav nrog cov khoom zaum kub - tag nrho cov no rau txim Ca-Zn nyuaj dua lawv rau txim txhuas. Lub Hoobkas nrog cov txheej txheem nruj tswj ua tau zoo heev Ca-Zn ntawv. Lub Hoobkas tsis muaj nws ua daim ntawv nrog cov streaks dub uas tshwm hauv nruab nrab ntawm lub pallet.
Qhov no txhais tau tias cov lus nug stabilizer thiab cov lus nug ntawm tus neeg muag khoom yog tib lo lus nug. Kev yuav Ca-Zn los ntawm tus neeg muag khoom uas nws cov txheej txheem kev qhuab qhia koj tsis tau kuaj xyuas kev lag luam ib qho kev pheej hmoo rau lwm qhov tsis yog tshem tawm.
