Cov Khoom Siv Kub Sib Xyaws
Cov Khoom Siv Kub Sib Xyaws
Cov tshuaj stabilizers ua los ntawm cov ntsev ua ke tsis yog tsuas yog muaj kev ruaj khov zoo thiab siv tau ua lub ntsiab pvc stabilizer rau cov khoom PVC, tab sis kuj muaj lawv tus kheej cov yam ntxwv ywj pheej, uas yuav tsum tau them sai sai rau thaum siv lawv. Raws li ntau xyoo ntawm kev tsim qauv mis, cov ntsiab lus uas yuav tsum tau them sai sai rau thaum siv cov tshuaj monomeric lead salt stabilizers tau muab tso ua ke raws li hauv qab no:
1. Nkag siab txog cov yam ntxwv thiab cov sijhawm siv ntawm txhua lub tshuaj stabilizer ntsev ua ke, thiab sim thiab kho nws hauv kev xyaum.
Txhua lub tshuaj stabilizer ua los ntawm cov ntsev txhuas muaj nws tus kheej cov yam ntxwv thiab ntau yam kev siv. Yog tias peb xav siv lub stabilizer zoo, peb yuav tsum nkag siab txog nws cov yam ntxwv, paub tias nws muaj txiaj ntsig zoo li cas, thiab tsis haum rau kev siv. Piv txwv li, dibasic lead phosphite muaj kev tiv thaiv huab cua zoo, thiab nws cov txiaj ntsig tuaj yeem siv tau tag nrho hauv cov khoom siv sab nraum zoov uas hais txog kev tiv thaiv huab cua, yog li nws feem ntau ua lub stabilizer tseem ceeb hauv cov khoom no, thaum tribasic lead sulfate muaj kev ua haujlwm zoo heev, tuaj yeem siv ua lub stabilizer tseem ceeb hauv lub sijhawm xav tau kev ruaj ntseg thermal siab.
2. Xaiv lub stabilizer tsim nyog raws li cov txheej txheem ua tiav thiab daim ntawv thov tshwj xeeb
Cov khoom sib txawv muaj cov kev cai sib txawv, thiab cov stabilizers sib txawv yuav tsum tau xaiv. Cov khoom siv sib txawv thiab cov xwm txheej ua tiav muaj cov kev cai sib txawv rau cov stabilizers. Peb ua tib zoo xav txog cov xwm txheej siv tshwj xeeb hauv kev tsim cov qauv thiab xaiv cov stabilizer sib txawv thiab kev sib xyaw ua ke. Dosage. Ntawm cov khoom tseem ceeb, cov kav dej feem ntau tsis xav tau kev tiv thaiv huab cua siab, yog li tribasic lead sulfate nrog kev ruaj khov thermal zoo feem ntau yog siv ua lub stabilizer tseem ceeb. Tsis tas li ntawd, vim yog cov duab yooj yim ntawm cov kav dej thiab keeb kwm thermal luv luv thaum lub sijhawm ua tiav, qhov ntau ntawm stabilizer tsis loj heev.
3. Cov nyhuv synergistic ntawm cov stabilizers
Muaj peb qhov sib txawv ntawm kev sib xyaw ua ke ntawm cov stabilizers: ib qho yog qhov synergistic effect, uas yog qhov cuam tshuam ntawm 1 + 1> 2; qhov tod yog qhov additive effect, uas yog qhov cuam tshuam ntawm 1 + 1 = 2; qhov tod yog qhov antagonistic effect, uas yog Qhov cuam tshuam ntawm 1 + 1 <2. Peb yuav tsum ua tib zoo nkag siab txog kev sib cuam tshuam ntawm cov stabilizers sib txawv thaum tsim cov qauv tsim, siv ntau dua ntawm qhov synergistic effect ntawm cov stabilizers, thiab sim peb qhov zoo tshaj plaws kom tsis txhob muaj qhov sib cav sib ceg ntawm cov stabilizers, yog li kom tau txais lub kaw lus stabilizer cua sov uas pheej yig.
1. Tus nqi qis ntawm cov tshuaj stabilizers ua los ntawm cov ntsev txhuas yog tus nqi qis tshaj plaws ntawm txhua cov tshuaj stabilizers, yog li txawm hais tias muaj kev qhia txog cov tshuaj stabilizers tshiab tas li, cov tshuaj stabilizers ua los ntawm cov ntsev txhuas tseem nyob hauv kev lag luam tseem ceeb rau cov tshuaj stabilizers ib nrab xyoo tom qab;
2. Qhov tshuaj lom ntawm cov tshuaj lom txhuas ntsev stabilizers txwv nws daim ntawv thov hauv ntau lub sijhawm nrog cov kev cai huv huv nruj;
3, tsis zoo dispersibility ntsev lead dispersibility yog pluag, tab sis cov khoom tshiab tso tawm nrog lubricants, los ntawm ib qho twg los daws qhov teeb meem ntawm dispersibility
1. Zoo heev txhim kho qhov sib npaug ntawm kev sib tov thiab kev sib kis nrog cov tshuaj resin;
2. Tsim nyog thiab ua haujlwm tau zoo sab hauv thiab sab nraud lubrication collocation;
3. Pab txhawb kev tsim khoom thiab kev tswj xyuas zoo;
4. Thaum cov mis sib xyaw, tus naj npawb ntawm cov sijhawm ntsuas tau yooj yim dua.
