Titanium Dioxide uas soj ntsuam kev kawm zauv rau cov
Nov 17, 2015

Pub ntxiv tshaj ntawm titanium dioxide uas, yuav muaj ib tug ntxim rau rheological zog cov uas khiav. Ntxiv ntawv, uas yuav muaj ib qhov nyhuv. Dawb masterbatch (tshwj xeeb yog END hom) nyob rau hauv daim ntawv thov titanium dioxide, thiab ua kev soj ntsuam yuav tsum raug npaj, zoo thiab disadvantages titanium dioxide ua ua ntau lawm efficiency thiab nqi yog cov tseem ceeb tshaj.

Machinability ntawm titanium dioxide dynamic torque rheological txoj kev no yuav muab siv rau qhov kev tshuaj ntsuam. Kev kuaj hauv raws xyaw es thiaj nrhiav thiab ntxuav cov kub, ntaub ntawv lub sij hawm uas xeeb cov nyiaj pab ntau tshaj torque, yeej yog cov khoom yas lub sij hawm, vim tias thaum cov khoom no tag plasticized torque yuav tau txo ntev tom qab judging, lwm hom titanium dioxide tsis ua kom muaj kev sib txawv li cas plasticizing sij hawm. Uas khiav hauv qhov khoom ua, plasticizing sij hawm txiav txim los ntawm tus kub siab thiab shear txhuam nyhuv. Ntau hom kev titanium dioxide, thermal conductivity, hardness, thiab kev sib txhuam of coefficient tsis yog qhov txawv ntau, ntau npaum sib npaug ntawm yas thermal conductivity thiab shear txhuam nyhuv yeej dua qub, plasticizing tsis txawv. Torque torque ntau thiab tshuav nyiaj li cas, txo qhov txheej txheem yuav du, hwj huam noj kuj muaj tsawg. Tom qab muab titanium rau yas, viscosity si liquidity, nws nyuaj mus kev, thiab torque kuas ncaj qha qhia li ntawv lawv kawg viscosity, tshuav tsawg torque lawv ntawd Machinability ntawm titanium dioxide tau tsim.

Thiaj li yuav xaiv ib tug polymer xyuas cov neeg mob, uas kev lag luam txiav txim los ntawm khoom rheological polymer kua torque rheometer, Brabender torque muaj rheometer (Braband) rheometer Hake (Huck) rheometer. Hom ntsuas tau simulate tiag polymer molding txoj kev mob uas siv los txiav txim txog ntawm rheological zog ntawm polymer nyob rau hauv tus txheej txheem, thiab xaiv seb cov tshuab rau polymer ua zoo tshaj plaws. Nyob twj ywm xab polymer uas muab caij rheological ntsuas rau txoj kev xyuas Shi, kev txiav txim txog qhov rheological ntsuas ntawm tus nqi muab caij, thiab tus nqi khoom kub, thiab yaj siab lub cev thiab lub sij hawm ua hauj lwm, parameter, poom painting tawm yog xab polymer "txoj kev ua" Shi uas muab caij-sij hawm nkhaus, nkhaus kub-lub sij hawm, thiab tau raws li txiav txim plaub ntug polymer yaj lub cev ntawm pas degrees hloov qhov xwm txheej ntawd (uas muab caij tus nqi hloov li) , melting hauv tus muaj zog noj li, melting cov yam ntxwv, kub sij hawm ruaj khov, thiab tus polymer ntawm cov yam ntxwv decomposition, series txheej txheem parameter, rau teb rau yaj polymers tus xyuas txog kev muab cov ntaub ntawv kev tsim nyog.
