Txhawb Kev Lag Luam Roj Hmab: Kev Hloov Kho Daim Ntawv Thov ntawm Isopropyl Distearoyl Aluminate hauv Kev Txhim Kho Cov Fillers
Nyob rau hauv cov txheej txheem ntawm cov khoom siv roj hmab, qhov sib ntxiv ntawm cov khoom siv ntxiv xws li carbon dub, silica, av nplaum, thiab lwm yam, yog qhov tseem ceeb rau kev txhim kho cov khoom siv ntawm cov khoom. Txawm li cas los xij, qhov kev tsis sib haum xeeb ntawm cov fillers thiab cov roj hmab matrix yeej ib txwm yog ib qho kev txwv tsis pub muaj kev txhim kho ntxiv ntawm cov khoom lag luam. Lub sijhawm no, tus neeg sawv cev aluminate sib txuas ua tau zoo dhau los ua tus yuam sij rau kev rhuav tshem qhov kev tuag. Isopropyl distearoyl aluminate, ua ib qho zoo heev aluminate coupling tus neeg saib xyuas, nthuav tawm qhov zoo tshaj plaws hauv kev txhim kho cov khoom sib cais thiab ua kom tiav kev ua tau zoo ntawm cov roj hmab tag nrho. Shandong Chunqian Cov Khoom Siv Tshiab, raws li tus kws tshaj lij ntawm cov neeg ua haujlwm sib txuas ntawm aluminate, muab lub zog muaj zog rau kev txhim kho kev lag luam roj hmab nrog nws cov kev txiav -ntug thev naus laus zis.
1. Core mechanism: Los ntawm "lub cev doping" mus rau "chemical bonding"
Isopropyl distearoyloxy aluminate, raws li tus neeg sawv cev zoo aluminate coupling, boasts ib tug ntse tsim qauv molecular. Cov pab pawg isopropoxy ntawm ib kawg tuaj yeem ua tshuaj lom neeg nrog cov pab pawg hydroxyl nyob rau saum npoo ntawm cov khoom siv xws li carbon dub, silica, thiab av nplaum, ua kom muaj zog Al-O-Si lossis Al-O- tshuaj bonds. Lub caij no, cov saw ntev stearoyloxy nyob rau lwm qhov kawg qhia txog kev sib raug zoo thiab kev cuam tshuam nrog roj hmab molecular chains. Qhov no yog zoo li txhim kho qhov ruaj khov "molecular choj" ntawm inorganic fillers thiab organic roj hmab, hloov lub cev yooj yim sib xyaw rau hauv cov tshuaj ruaj khov. Qhov kev hloov pauv hauv nruab nrab ntawm lub ntsej muag no ua lub hauv paus rau kev txhim kho kev ua haujlwm tom ntej.
II. Tsib qhov txiaj ntsig zoo hauv kev siv roj hmab
Tseem ceeb txhim khu lub dispersibility ntawm lub reinforcing muab tub lim
Untreated fillers yog nquag mus spontaneous agglomeration vim lub zog saum npoo, tsim cov ntsiab lus kev ntxhov siab. Thaum coated nrog no aluminate coupling tus neeg sawv cev, lub zog saum npoo ntawm cov khoom muab tub lim tau txo qis, hloov ntawm hydrophilic mus rau oleophilic, yog li txhim kho lawv kev sib raug zoo nrog cov roj hmab matrix. Qhov no txhais tau hais tias cov fillers xws li carbon dub thiab silica tuaj yeem sib npaug thiab ruaj khov nyob hauv cov roj hmab, kom tsis txhob muaj kev ntxhov siab hauv zos los ntawm agglomeration, nteg lub hauv paus ruaj khov kom tau txais cov khoom sib xws thiab siab -kev ua haujlwm vulcanized roj hmab.
Comprehensively txhim khu lub mechanical zog ntawm roj hmab
Tensile zog
Cov khoom sib cais sib cais yog nruj nreem khi rau cov roj hmab matrix los ntawm kev sib txuas ntawm cov tshuaj aluminate coupling. Raws li kev quab yuam sab nraud, kev ntxhov siab tuaj yeem hloov tau zoo dua los ntawm cov roj hmab matrix mus rau qhov siab -modulus filler particles, yog li ua kom cov modulus ntawm qhov txuas ntxiv thiab lub zog tensile ntawm cov khoom sib xyaw.
kua muag zog
Zoo interfacial bonding tiv thaiv kev nthuav tawm ntawm cov kab nrib pleb ntawm qhov sib cuam tshuam ntawm cov muab tub lim thiab roj hmab. Thaum cov khoom raug rhuav tshem quab yuam, cov kab nrib pleb yuav tsum muaj zog ntau dua los nthuav tawm, yog li nthuav tawm cov kua muag zoo heev.
Hnav tsis kam
Qhov zoo dispersion thiab ruaj khov kev sib txuas ntawm cov khoom ua kom cov roj hmab saum npoo los tsim cov txheej txheem tiv thaiv kom muaj zog thiab ntau dua, uas tsis tshua muaj tev thiab hnav thaum muaj kev sib txhuam, ua kom ntev lub neej ntawm cov khoom.
Ua kom zoo txo cov viscosity ntawm cov roj hmab compound thiab txhim kho nws cov fluidity
Cov saw ntev ntawm stearoyl oxy pawg ntawm cov molecular kawg ntawm no aluminate coupling tus neeg saib xyuas pom zoo lubricating zog. Thaum lub sij hawm sib tov, nws tuaj yeem cais cov coated muab tub lim zoo, txo cov kev sib txhuam sab hauv ntawm cov khoom, yog li txo qhov Mooney viscosity ntawm cov roj hmab compound. Qhov no ua rau cov roj hmab sib xyaw siv lub zog tsawg dua thaum qhib milling lossis sib xyaw ua ke, thiab yooj yim rau extrude, calender, thiab pwm, zoo heev txhim kho cov txheej txheem thiab tseem pab txo cov khoom ua haujlwm ntawm cov khoom siv ntau lawm.
Tso cai rau kev sau ntau dua kom ua tiav cov nqi optimization
Vim qhov kev txhim kho hauv kev sib cais thiab txo qis hauv viscosity, kev siv cov khoom siv kho nrog cov khoom no tso cai rau kev ua kom zoo dua qub yam tsis muaj kev cuam tshuam kev ua haujlwm thiab cov khoom siv lub cev kawg. Rau cov khoom siv roj hmab uas xav tau cov khoom ntim ntau, xws li cov khau khau, cov hlua khi, cov ntaub qhwv lub cev, thiab lwm yam, qhov no txhais tau hais tias thaum tuav lossis txhim kho kev ua tau zoo, tus nqi ntawm cov khoom siv raw tuaj yeem txo qis, txhim kho kev lag luam kev sib tw ntawm cov khoom.
Nws yog tshwj xeeb tshaj yog haum rau silica dawb filling tshuab
Hauv cov log tsheb ntsuab lossis lub teeb -cov khoom siv roj hmab muaj xim uas muaj silica, ntau ntawm silanol pawg nyob rau saum npoo ntawm silica yog thawj qhov laj thawj rau nws yooj yim agglomeration. Cov khoom no tuaj yeem ua rau muaj txiaj ntsig zoo nrog cov pab pawg hydroxyl, kov yeej qhov nyuaj ntawm kev sib cais ntawm silica, uas yog qhov tseem ceeb rau kev ua tiav qib siab - cov ntsuas kev ua tau zoo xws li txo cov dov tsis kam thiab txhim kho kev tuav ntub dej.
III. Synergistic Advantages ntawm Shandong Chunqian Cov Khoom Tshiab
Xaiv isopropyl distearoyl aluminate los ntawm Shandong Chunqian Cov Khoom Tshiab txhais tau tias tau txais kev daws teeb meem. Chunqian Cov Khoom Tshiab 'aluminate coupling tus neeg sawv cev muaj npe nrov rau nws cov purity siab, siab reactivity, thiab zoo heev batch stability.
