Kev ua tiav thiab daim ntawv thov tus nqi ntawm aluminate coupling agents hauv kev lag luam PVC Hauv kev ua cov khoom siv polyvinyl chloride (PVC), ntsuas cov khoom ua tau zoo, cov nqi tsim khoom, thiab kev siv thev naus laus zis ib txwm yog qhov teeb meem tseem ceeb ntawm kev lag luam. Raws li kev hloov pauv hloov pauv tau zoo, aluminate coupling cov neeg ua haujlwm tau coj cov kev daws teeb meem tshiab rau PVC kev lag luam, ua kom pom tus nqi tshwj xeeb hauv kev txhim kho cov khoom sib cais, txhim kho cov khoom lag luam, thiab txo cov nqi tsim khoom.
I. Technical Principple:
Cov qauv molecular ntawm aluminate coupling tus neeg sawv cev, uas ua kom ruaj khov PVC -filler interface, muaj cov yam ntxwv amphiphilic. Cov pab pawg aluminate ntawm ib qho kawg tuaj yeem tsim cov tshuaj tiv thaiv ruaj khov nrog cov pab pawg ua haujlwm ntawm cov khoom siv tsis zoo xws li calcium carbonate thiab titanium dioxide. Cov saw hlau ntev ntev ntawm lwm qhov kawg pom zoo sib xws nrog PVC molecular saw. Cov qauv tshwj xeeb no tsim kom muaj kev sib txuas tshuaj muaj zog ntawm cov muab tub lim thiab PVC matrix.
Thaum lub sij hawm ua cov khoom ntawm PVC, aluminate coupling agents exert lawv cov teebmeem los ntawm peb lub ntsiab technical mechanisms:
Deg tshuaj hloov kho mechanism:
Hloov cov khoom saum npoo ntawm cov muab tub lim kom txhim khu kev sib raug zoo nrog PVC cob;
Dispersion thiab stability tswj mechanism:
Tsim cov nyhuv steric hindrance los tiv thaiv agglomeration ntawm fillers thaum ua;
Interfacial mechanical txhim khu kev qha mechanism:
Tsim kom muaj kev sib txuas tshuaj ruaj khov los txhim kho cov khoom siv hluav taws xob ntawm cov khoom sib xyaw.
II. Professional thiab Technical Advantages Applied in the PVC Industry
1. Txhim kho cov cuab yeej cuab tam ntawm cov khoom tseem ceeb
Nyob rau hauv PVC formulations, untreated fillers yog nquag mus ua kev nyuaj siab concentration ntsiab lus. Aluminate coupling agents hloov cov fillers los ntawm "cov chaw tsis muaj zog" mus rau "cov ntsiab lus ntxiv dag zog" los ntawm kev txhim kho kev sib txuas ntawm lub ntsej muag. Cov ntaub ntawv thov tiag tiag qhia tau hais tias PVC cov khoom hloov kho nrog aluminate coupling agents tuaj yeem muaj 25% -40% nce tensile lub zog, 30% -50% kev txhim kho hauv kev cuam tshuam lub zog, thiab 20% -35% kev txhim kho hauv kev khoov lub zog, txhim kho qhov ruaj khov thiab kev ntseeg siab ntawm cov khoom xws li cov kav dej thiab cov kav dej.
2. Optimize kev ua tau zoo thiab ntau lawm efficiency
PVC ua tiav xav tau siab rheological zog ntawm cov yaj. Tom qab aluminate coupling tus neeg saib xyuas txhim kho lub xeev dispersion ntawm lub muab tub lim, lub yaj lub fluidity yog ho txhim kho. Tshwj xeeb, qhov extrusion siab txo los ntawm 15% -25%, thiab kev siv hluav taws xob raug txo qis; kev ruaj ntseg ntawm cov khoom molding yog txhim kho, thiab qhov zoo ntawm qhov chaw yog ho txhim khu kev qha; ntau lawm efficiency yog nce los ntawm 18% -30%, ua nws tshwj xeeb tshaj yog haum rau high-ceev extrusion thiab txhaj tshuaj molding txheej txheem.
3. Ua tau zoo filling thiab economic optimization
Aluminate coupling agents tsim tej yam kev mob rau siab -feem ntau filling los ntawm kev txhim kho interfacial compatibility. Kev lag luam kev xyaum qhia tau hais tias qhov zoo tshaj qhov sib ntxiv ntawm aluminate coupling agents rau PVC yog tswj los ntawm 5% thiab 10% ntawm qhov ntom, uas tso cai rau kev nyab xeeb ntawm cov muab tub lim ntxiv, xws li calcium carbonate, mus rau 40% mus rau 60%. Thaum tswj xyuas cov khoom ua tau zoo, nws txo qis cov nqi raw khoom los ntawm 25% mus rau 40%.
4. Txhim kho qhov zoo thiab ruaj khov ntawm cov khoom
Cov muab tub lim hloov tau sib npaug ntau dua nyob rau hauv PVC matrix, ua rau cov khoom lag luam smoother thiab flatter nrog 20% -35% nce hauv glossiness thiab 30% -50% txo qhov tsis xws luag. Nyob rau tib lub sij hawm, qhov seem stability, tshav kub tsis kam, thiab huab cua tsis kam ntawm cov khoom kuj tseem ho txhim kho.
5. Txhim khu lub peev xwm ntawm kev ua haujlwm tau zoo
Qhov saum npoo ntawm cov muab tub lim kho nrog cov neeg ua haujlwm sib txuas muab lub platform zoo dua qub rau lwm cov khoom siv ntxiv. Thaum siv ua ke nrog cov cua sov stabilizers, lubricants, nplaim retardants, thiab lwm yam., nws muaj peev xwm ua tau ib tug tseem ceeb synergistic nyhuv, muab kev pab rau kev loj hlob ntawm high -kev ua tau zoo ntawm PVC khoom.
III. Kev Pab Txhawb Kev Ua Haujlwm:
Raws li ib tug qub tub rog chaw tsim tshuaj paus ntawm aluminate coupling agents, Shandong Chunqian New Materials Co., Ltd.
IV. Kev siv tswv yim
Effect Verification A PVC profile manufacturing enterprise thawj zaug ntsib teeb meem xws li cov khoom tsis txaus lub zog thiab ntxhib nto thaum siv cov calcium carbonate zoo tib yam li cov muab tub lim. Tom qab qhia tus neeg sawv cev aluminate coupling muab los ntawm Chunqian Cov Khoom Tshiab (nrog rau qhov sib ntxiv ntawm 8% ntawm qhov muab tub lim), calcium carbonate filling tus nqi tau nce los ntawm 35% mus rau 50%. Nyob rau tib lub sijhawm, qhov cuam tshuam lub zog ntawm cov khoom tau nce los ntawm 45%, lub zog tensile nce los ntawm 32%, lub ntsej muag gloss zoo dua los ntawm 40%, tag nrho cov nqi txo los ntawm 30%, thiab kev ua lag luam kev sib tw ntawm cov khoom tau nce ntxiv.
V. Application Fields thiab Development Trends Daim ntawv thov ntawm aluminate coupling agents hauv PVC kev lag luam npog ntau qhov chaw:
Lub tsev profiles:Txhim kho cov khoom siv kho tshuab thiab huab cua tsis kam ntawm profiles;

Raws li kev lag luam PVC hloov zuj zus mus rau kev ua tau zoo dua thiab ib puag ncig tus phooj ywg, aluminate coupling agents muaj cov ntawv thov dav dav hauv thaj chaw tshiab xws li lead-cov tshuab tsis pub dawb thiab cov tshuab yas zoo ib puag ncig.
VI. Cov tswv yim siv scientific:
Xaiv cov qauv sib txuas tsim nyog raws li cov khoom siv PVC;
Txiav txim siab qhov txiaj ntsig zoo ntxiv los ntawm kev sim, thiab ua kom zoo dua li ntawm 5% -10%;
nruj me ntsis tswj cov txheej txheem kub thiab sib tov lub sij hawm;
Ua tib zoo saib xyuas kev sib raug zoo nrog stabilizers, lubricants, thiab lwm yam additives;
Tsim kom muaj kev tswj xyuas zoo kom paub meej cov khoom ruaj khov.
Aluminate coupling agents ua lub luag haujlwm tseem ceeb hauv PVC kev lag luam los ntawm lawv cov kev hloov kho kev hloov kho thev naus laus zis. Lawv tsis tsuas yog daws tau cov teeb meem kev sib tw ua tau zoo los ntawm kev ua haujlwm siab, tab sis kuj muab cov kev daws teeb meem rau kev lag luam kom txo tau cov nqi thiab ua kom muaj txiaj ntsig zoo. Shandong Chunqian New Material Co., Ltd., raws li cov kws tshaj lij kev tsim khoom, tau dhau los ua tus khub txhim khu kev qha rau PVC cov tuam txhab hauv kev tsim kho tshiab thiab cov khoom lag luam kho dua tshiab, ua tsaug rau nws cov kev pabcuam raws sijhawm, tau lees paub tom qab- kev cog lus muag, thiab muaj peev xwm cia ntau, ua ke nrog ntau xyoo ntawm kev tsim khoom thiab kev muag khoom. Nrog kev nce qib ntawm cov khoom siv thev naus laus zis tsis tu ncua, aluminate coupling agents yuav muaj tseeb ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa siab - kev txhim kho zoo ntawm PVC kev lag luam.
