Daim ntawv thov tus nqi thiab kev tsim kho tshiab ntawm Aluminate Coupling Agent hauv Polypropylene Drawing Filler Kev Lag Luam
Hauv kev lag luam polypropylene hlau kos duab khoom lag luam, kev ua haujlwm ntawm cov khoom xws li woven hnab, thawv ntim, geotextiles, ropes, thiab lwm yam yog ncaj qha ntsig txog lawv lub neej kev pabcuam thiab kev nyab xeeb ntawm daim ntawv thov. Nrog rau kev nce ntxiv hauv cov nqi raw khoom thiab nce ib puag ncig nruj, yuav ua li cas ntxiv cov khoom siv tsis zoo xws li calcium carbonate thiab talc hmoov rau polypropylene (PP) cov khoom siv hlau los txo cov nqi thaum tswj lossis txawm tias txhim kho cov khoom siv thiab kev ruaj ntseg ntawm cov khoom siv hlau kos duab tau dhau los ua teeb meem ceev hauv kev lag luam. Aluminium ester coupling tus neeg sawv cev, raws li kev hloov pauv hloov pauv tau zoo, muab cov tswv yim thiab ua tau zoo rau kev lag luam polypropylene hlau kos duab los ntawm nws qhov tshwj xeeb "molecular bridging" cov nyhuv, thiab tau dhau los ua cov khoom tseem ceeb los txhawb kev kawm txuj ci thiab kev txhim kho hauv kev lag luam.
1, Lub mechanism ntawm kev txiav txim ntawm txhuas ester coupling tus neeg saib xyuas nyob rau hauv polypropylene hlau daim duab muab tub lim
Cov qauv molecular ntawm aluminium ester coupling cov neeg ua haujlwm muaj cov yam ntxwv ntawm amphiphilic: pawg aluminium ester ntawm ib kawg tuaj yeem tsim cov tshuaj lom neeg ruaj khov nrog cov pab pawg ua haujlwm nyob rau saum npoo ntawm inorganic fillers xws li calcium carbonate thiab talc hmoov, ua tiav cov txheej txheej ntawm muab tub lim; Cov organic ntev - cov qauv saw ntawm lwm qhov kawg muaj kev sib raug zoo nrog polypropylene molecular chains thiab tuaj yeem tsim kev sib raug zoo los ntawm kev cuam tshuam ntawm cov saw hlau molecular.
Hauv kev tsim thiab ua ntawm polypropylene hlau kos duab fillers, aluminate coupling cov neeg ua haujlwm feem ntau ua lub luag haujlwm peb npaug:
Surface activation hloov kho:
Cov nyhuv hloov kho deg: Los ntawm kev sib koom ua ke thiab npog lub ntsej muag ntawm cov muab tub lim, lub zog saum npoo ntawm cov khoom muab tub lim tau txo qis, txhim kho lawv cov wettability thiab affinity nrog polypropylene resin, thiab transforming lub keeb kwm hydrophilic muab tub lim rau hauv hydrophobic.
Dispersion stability txhim khu kev qha:
Dispersion stabilization nyhuv: Ib txheej steric hindrance yog tsim nyob rau saum npoo ntawm cov khoom muab tub lim, zoo tiv thaiv lawv los ntawm kev sib sau ua ke vim van der Waals rog thaum ua thiab khaws cia, ua kom zoo ib yam thiab ruaj khov dispersion ntawm qib micrometer hauv resin matrix.
Interface kev nyuaj siab kis tau tus mob:
Interface txhim kho kev ua haujlwm: Tsim kom muaj cov tshuaj muaj zog "choj" ntawm cov muab tub lim thiab polypropylene resin interface, tsim cov organic tag nrho ntawm ob. Thaum cov khoom raug rau sab nraud quab yuam, kev ntxhov siab tuaj yeem kis tau zoo los ntawm qhov kev sib tshuam no, tsis txhob tsim cov ntsiab lus ntawm kev ntxhov siab nyob ib ncig ntawm lub muab tub lim thiab ua rau cov hlau puas.
2, Cov txiaj ntsig zoo ntawm kev siv polypropylene hlau kos duab sau cov khoom
1. Txhim kho cov cuab yeej cuab tam ntawm cov khoom kos
Nyob rau hauv cov tsoos polypropylene xaim kos duab fillers, cov khoom siv tsis kho feem ntau dhau los ua cov ntsiab lus tsis zoo, cuam tshuam rau lub zog tensile, lub zog nodule, thiab hnav tsis kam ntawm hlau kos duab. Aluminium ester coupling cov neeg ua haujlwm txhim kho kev sib txuas ntawm kev sib txuas, ua kom cov khoom ntim tau zoo thiab xa cov kev ntxhov siab. Cov ntaub ntawv siv tau pom tau hais tias ntxiv qhov tsim nyog ntawm tus neeg sawv cev sib txuas rau cov khoom ntim tuaj yeem ua rau lub zog tensile ntawm polypropylene kos duab los ntawm 20% -30%, thiab elongation ntawm kev tawg los ntawm 15% -25%, txhim kho lub peev xwm thauj khoom thiab kev pabcuam lub neej ntawm cov hnab ntim khoom, lub hnab ntim khoom thiab lwm yam khoom.
2. Txhim kho kev ua haujlwm fluidity thiab ntau lawm stability
Kev tsim cov txheej txheem ntawm polypropylene hlau daim duab yuav tsum tsis tshua muaj siab rheological zog ntawm cov yaj. Aluminium ester coupling tus neeg saib xyuas txhim kho lub xeev kev sib txuas ntawm cov muab tub lim thiab cov cob, ua rau cov yaj viscosity ruaj khov thiab cov dej ntws tau zoo tuaj. Qhov no txhais tau tias cov ntsia hlau torque raug txo los ntawm 10% -15%, uas ua rau muaj kev txo qis hauv kev siv zog; Cov txheej txheem spinning yog ruaj khov dua, thiab tus nqi tawg tau txo qis; Txhim kho kev ua haujlwm zoo thiab cov khoom lag luam tawm los ntawm cov kab ntau lawm, tshwj xeeb tshaj yog tsim rau high-speed hlau kos duab ntau lawm kab.
3. Optimize qhov tsos thiab nto zoo ntawm cov khoom
Cov muab tub lim kho nrog aluminium ester coupling tus neeg sawv cev yog sib npaug sib npaug hauv cov polypropylene matrix, uas ua rau lub ntsej muag ntawm lub rub tawm filament smoother thiab ntau yam zoo, txo qhov tshwm sim ntawm fuzz thiab tawg. Qhov no tsis tsuas yog txhim kho cov tsos zoo ntawm cov ntaub, tab sis kuj txhim khu kev ua tau zoo ntawm cov txheej txheem weaving tom ntej thiab txo qis sijhawm.
4. Ua tau zoo filling thiab nqi optimization
Kev nce tus nqi filling yog ib txoj hauv kev zoo tshaj plaws los txo cov nqi tsim khoom thaum ua kom ntseeg tau qhov kev ua tau zoo. Aluminium ester coupling cov neeg ua haujlwm txhim kho cov dispersibility thiab interfacial bonding ntawm cov muab tub lim, ua kom siab filling ua tau yam tsis muaj kev txi ntau dhau. Cov ntaub ntawv thov kev lag luam qhia tau hais tias kev tswj hwm qhov sib ntxiv ntawm aluminium ester coupling tus neeg sawv cev rau polypropylene hlau kos duab muab tub lim nruab nrab ntawm 5% -10% ntom tuaj yeem ua kom cov nyiaj ntxiv ntawm calcium carbonate thiab lwm cov fillers mus rau 30% -40%, thaum tuav cov kev ua haujlwm tseem ceeb ntawm cov hlau kos duab raws li kev xav tau. Lub tshuab filling siab no tuaj yeem txo cov nqi raw khoom los ntawm 15% -25%, tsim cov txiaj ntsig kev lag luam tseem ceeb rau cov tuam txhab kos duab kos duab.
5. Txhim kho huab cua tsis kam thiab kev ua haujlwm ntawm cov khoom
Qhov saum npoo ntawm fillers kho nrog coupling cov neeg ua haujlwm yog qhov ua rau muaj kev cuam tshuam nrog lwm cov khoom siv ntxiv. Piv txwv li, thaum siv ua ke nrog cov tshuaj tiv thaiv kev laus, UV absorbers thiab lwm yam khoom siv ntxiv, nws tuaj yeem ua lub luag haujlwm ntawm ntau yam additives, txhim kho huab cua tiv thaiv thiab kev pab cuam lub neej ntawm polypropylene hlau kos duab khoom, thiab tshwj xeeb tshaj yog haum rau cov khoom siv sab nraum zoov.
