Aluminium ester coupling tus neeg sawv cev: ib qho "txhim kho" rau kev hloov pauv thiab kho dua tshiab ntawm kev lag luam casting film filling khoom
Nyob rau hauv niaj hnub yas zaj duab xis ua technology, cam khwb cia zaj duab xis occupies ib tug tseem ceeb txoj hauj lwm nyob rau hauv lub teb xws li cov zaub mov ntim, cov ntaub ntawv kho mob, hluav taws xob tiv thaiv, thiab lwm yam vim nws thickness uniformity, zoo heev optical zog, thiab ruaj khov lub cev. Txawm li cas los xij, nrog kev nce ntxiv hauv cov nqi raw khoom thiab nce kev nruj ib puag ncig, yuav ua li cas txo cov nqi los ntawm kev ntxiv cov khoom siv tsis zoo xws li calcium carbonate thiab talc hmoov thaum tuav cov kev ua tau zoo ntawm cov yeeb yaj kiab cam khwb cia, thiab tib lub sijhawm txhim kho lossis tswj cov kev ua tau zoo ntawm cov yeeb yaj kiab, tau dhau los ua qhov teeb meem tseem ceeb uas kev lag luam txuas ntxiv tshawb nrhiav. Aluminium ester coupling tus neeg saib xyuas, raws li cov khoom siv hloov pauv hloov pauv tau zoo, yog ib qho tseem ceeb ntawm kev siv los daws qhov teeb meem no.
1, Lub hauv paus ntsiab lus ntawm kev ua ntawm aluminium ester coupling tus neeg sawv cev hauv cov khoom ntim ntawm cov yeeb yaj kiab casting
Cov qauv molecular tsim ntawm aluminium ester coupling cov neeg ua haujlwm yog qhov tshwj xeeb thiab muaj cov yam ntxwv "amphiphilic": cov pab pawg aluminium ester ntawm ib kawg ntawm cov molecule tuaj yeem tsim cov tshuaj ruaj khov nrog cov pab pawg nquag (xws li hydroxyl pawg) rau ntawm qhov chaw ntawm inorganic fillers xws li calcium carbonate thiab talc hmoov, ua tiav cov txheej txheem ntawm cov muab tub lim; Cov organic ntev - cov qauv saw nyob rau lwm qhov kawg ntawm cov molecule muaj kev sib raug zoo nrog cov khoom siv matrix feem ntau rau cov yeeb yaj kiab xws li polypropylene (CPP), polyethylene (CPE), thiab polyamide (PA), thiab tuaj yeem ua tiav kev sib raug zoo los ntawm cov saw hlau molecular entanglement lossis van der Waals rog.
Hauv kev tsim thiab ua cov yeeb yaj kiab casting, aluminate coupling cov neeg ua haujlwm feem ntau ua lub luag haujlwm tseem ceeb triple:
Nto hloov cov nyhuv:
Nws txo qis lub zog saum npoo ntawm cov khoom siv inorganic, txhim kho lawv cov wettability thiab affinity nrog cov organic resins, thiab transforms lub hauv paus hydrophilic muab tub lim rau hauv hydrophobic.
Dispersion stabilization nyhuv:
Lub steric hindrance txheej 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 lawv zoo ib yam thiab ruaj khov dispersion ntawm nanometer lossis micrometer qib hauv resin matrix.
Kev nyuaj siab kis tau tus mob:
Tsim kom muaj cov tshuaj muaj zog "choj" ntawm qhov sib cuam tshuam ntawm cov muab tub lim thiab cov resin, 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, zam kev tsim cov ntsiab lus ntawm kev ntxhov siab nyob ib puag ncig cov muab tub lim thiab ua rau tsis ua haujlwm ntxov ntawm zaj duab xis.
2, Cov txiaj ntsig zoo siv rau cov khoom ntim ntawm cov yeeb yaj kiab casting
1. Txhim kho qhov zoo ntawm lub cev thiab lub zog ntawm cov yeeb yaj kiab
Rau siab filling npaum li cas cam khwb cia films, untreated fillers yog cov "shortcoming" nyob rau hauv lub mechanical zog ntawm cov zaj duab xis. Aluminium ester coupling cov neeg ua haujlwm txhim kho cov kev sib txuas ntawm kev sib txuas, hloov cov khoom siv los ntawm "cov ntsiab lus tsis raug" mus rau "cov ntsiab lus txhawb zog". Daim ntawv thov kev xyaum qhia tau hais tias kev siv cov fillers hloov nrog cov nqi tsim nyog ntawm aluminium ester coupling cov neeg ua haujlwm tuaj yeem ua rau lub zog tensile, elastic modulus, thiab kev cuam tshuam tsis zoo (tshwj xeeb tshaj yog qis-kub tsis kam) ntawm cov yeeb yaj kiab cam khwb cia los ntawm 15% -30%, txhim kho qhov ruaj khov ntawm zaj duab xis hauv lub hnab tom ntej, kev thauj mus los, thiab siv cov txheej txheem.
2. Ua kom zoo rau cov khoom siv kho qhov muag thiab cov tsos zoo ntawm cov yeeb yaj kiab
Cov kev xav tau rau pob tshab, tsis tshua muaj haze, thiab siab glossiness ntawm cam khwb cia zaj duab xis yog feem ntau siab dua li cov tshuab cua tshuab. Coupling cov neeg ua haujlwm zoo heev txo cov teeb tawg tshwm sim tshwm sim los ntawm kev sib sau ua ke los ntawm kev txhawb nqa qhov kawg dispersion ntawm fillers. Qhov no tso cai rau lub siab filling cam khwb cia ua kom muaj lub teeb xa hluav taws xob siab thiab qis qis, nrog lub ntsej muag zoo nkauj dua thiab ua kom zoo dua qub, ua tau raws li qhov xav tau nruj heev rau cov tsos zoo hauv siab - kawg ntim, cov khoom siv hluav taws xob tiv thaiv zaj duab xis, thiab lwm yam kev siv.
3. Txhim kho kev ua haujlwm fluidity kom ntseeg tau tias kev tsim khoom tas mus li thiab ruaj khov
Kev tsim cov yeeb yaj kiab cam khwb cia muaj cov yam ntxwv ntawm kev kub ceev, txuas ntxiv, thiab precision, thiab tsis tshua muaj siab rau cov khoom rheological ntawm cov yaj. Tom qab ntxiv aluminium ester coupling tus neeg sawv cev, lub yaj viscosity ntawm lub filling system txo qis, flowability nce, thiab ntws stability zoo. Qhov no coj tau ntau yam txiaj ntsig: txo cov extruder rov qab siab thiab torque, thiab txo qis zog noj; Txhim kho qhov sib xws ntawm cov yaj dhau los ntawm qhov tseeb tuag, ua kom muaj kev tswj xyuas ntau dua ntawm cov yeeb yaj kiab thickness tolerances; Txo cov yaj tawg thiab sharkskin tshwm sim, qis zaj duab xis breakage tus nqi, yog li ho txhim kho ntau lawm efficiency thiab cov khoom yield.
4. Ua tau zoo filling thiab zoo tswj cov nqi tsim khoom
Qhov no yog qhov qhia ncaj qha tshaj plaws ntawm kev lag luam tus nqi ntawm aluminium ester coupling agents. Los ntawm nws qhov kev ua kom nto thiab kev hloov kho, qhov sib xyaw ua ke thiab dispersibility ntawm fillers nyob rau hauv cov resin tau zoo heev, tso cai rau ib tug ntau yam ntawm cov filling ratio thaum xyuas kom meej tias cov khoom tseem ceeb ntawm cov zaj duab xis ua tau raws li cov qauv. Kev lag luam kev paub tau lees paub tias qhov kev pom zoo ntxiv ntawm aluminium ester coupling tus neeg sawv cev rau casting film fillers feem ntau yog tswj los ntawm 5% thiab 10% ntawm cov muab tub lim, uas tuaj yeem ua rau muaj qhov sib ntxiv ntawm cov khoom ua haujlwm. Piv txwv li, nyob rau hauv ib co CPP ntim zaj duab xis, qhov ntim ntawm calcium carbonate tuaj yeem ruaj ntseg nce mus rau 30% -40% lossis siab dua, ua tiav qhov txo qis ntawm 15% -25% hauv cov nqi raw khoom thaum tswj kev ua tau zoo, thiab yeej tus nqi tseem ceeb rau kev lag luam hauv kev sib tw ua lag luam hnyav.
5. Txhim khu kev ua haujlwm thiab nthuav dav daim ntawv thov
Lub interface ntawm cov muab tub lim kho nrog cov neeg sawv cev sib txuas tuaj yeem siv los ua lub platform los qhia ntxiv lossis koom tes nrog lwm cov khoom siv ntxiv. Piv txwv li, synergistically txhim kho qhov zoo li qub dissipation kev ua tau zoo ntawm cov yeeb yaj kiab nyias nrog cov tshuaj tiv thaiv zoo li -; Koom tes nrog barrier fillers los txhim kho zaj duab xis lub peev xwm los thaiv cov pa oxygen thiab dej vapor. Qhov no muab txoj hauv kev txhim khu kev qha rau kev txhim kho siab -kev ua tau zoo thiab tus nqi siab- ntxiv cov khoom siv yeeb yaj kiab tshwj xeeb xws li cov khoom ntim cov yeeb yaj kiab siab thiab tiv thaiv- cov yeeb yaj kiab tiv thaiv zoo li qub.
3, Kev txhawb nqa: Tus nqi pab ntawm Shandong Chunqian New Materials Co., Ltd
Daim ntawv thov cov nyhuv ntawm aluminium ester coupling tus neeg saib xyuas tsis yog nyob ntawm qhov kev ua tau zoo ntawm cov khoom nws tus kheej, tab sis kuj muaj peev xwm muab kev pab cuam ntawm tus neeg muag khoom. Shandong Chunqian New Materials Co., Ltd. tau dhau los ua tus khub zoo rau ntau cov yeeb yaj kiab casting thiab masterbatch ntau lawm kev lag luam raws li nws cov xyoo ntawm kev tsim khoom thiab kev muag khoom hauv kev ua haujlwm additives.
