Lead ntsev sib xyaw stabilizers tsis tsuas yog muaj kev ruaj ntseg zoo thiab tuaj yeem siv los ua lub ntsiab pvc stabilizer rau PVC cov khoom, tab sis kuj muaj lawv tus kheej cov yam ntxwv, uas yuav tsum tau them sai sai rau thaum siv lawv. Raws li ntau xyoo ntawm kev tsim qauv qauv, cov ntsiab lus uas yuav tsum tau them sai sai rau thaum siv monomeric lead ntsev stabilizers tau sau tseg raws li hauv qab no:
1. Ua kom tiav cov yam ntxwv thiab kev siv lub sijhawm ntawm txhua cov hlau lead ntsev sib xyaw kom ruaj khov, thiab sim thiab kho nws hauv kev xyaum.
Txhua cov hlau lead ntsev puas stabilizer muaj nws tus yam ntxwv ywj pheej thiab kev siv ntau yam. Yog tias peb xav siv lub stabilizer zoo, peb yuav tsum nkag siab tag nrho nws cov yam ntxwv, paub nyob rau hauv cov xwm txheej twg nws tuaj yeem qhia nws qhov zoo, thiab nyob rau hauv cov xwm txheej dab tsi tsis haum rau kev siv. Piv txwv li, dibasic lead phosphite muaj huab cua tsis zoo, thiab nws cov txiaj ntsig tuaj yeem siv tag nrho hauv cov khoom siv sab nraum zoov uas hais txog huab cua tsis kam, yog li nws feem ntau ua lub ntsiab stabilizer hauv cov khoom lag luam, thaum tribasic lead sulfate muaj kev ua haujlwm zoo thermal stability, muaj peev xwm ua tau zoo. siv los ua lub ntsiab stabilizer nyob rau hauv lub ntees yuav tsum siab thermal stability.
2. Xaiv lub stabilizer tsim nyog raws li cov txheej txheem tshwj xeeb thiab kev thov
Cov khoom sib txawv muaj qhov sib txawv, thiab cov stabilizer sib txawv yuav tsum tau xaiv. Cov cuab yeej sib txawv thiab cov txheej txheem ua haujlwm muaj qhov sib txawv rau cov stabilizers. Peb ua tib zoo xav txog cov kev thov tshwj xeeb hauv kev tsim qauv thiab xaiv qhov tsim nyog stabilizer ntau yam thiab kev sib xyaw ua ke. Kev noj tshuaj. Ntawm cov khoom tseem ceeb, cov kav dej feem ntau tsis tas yuav muaj huab cua ua haujlwm siab, yog li tribasic lead sulfate nrog thermal stability yog siv los ua lub ntsiab stabilizer. Tsis tas li ntawd, vim qhov yooj yim cross-sectional zoo ntawm cov yeeb nkab thiab cov keeb kwm luv luv thermal thaum lub sij hawm ua, tus nqi ntawm stabilizer tsis loj heev.
3. Synergistic nyhuv ntawm stabilizers
Muaj peb qhov sib txawv ntawm kev sib xyaw ua ke ntawm cov stabilizers: ib qho yog cov nyhuv synergistic, uas yog cov nyhuv ntawm 1 + 1> 2; lwm qhov yog cov nyhuv additive, uas yog cov nyhuv ntawm 1 + 1 = 2; Lwm qhov yog cov nyhuv antagonistic, uas yog Cov nyhuv ntawm 1 + 1 <2. Peb yuav tsum ua tib zoo tuav qhov kev sib cuam tshuam ntawm cov stabilizers sib txawv thaum tsim cov qauv tsim, ua kom muaj kev sib koom ua ke ntawm cov stabilizers, thiab sim peb qhov zoo tshaj plaws kom tsis txhob muaj kev sib cav sib ceg ntawm cov stabilizers, thiaj li yuav tau txais cov nqi hluav taws xob zoo.
1. Tus nqi qis ntawm cov hmoov lead ntsev stabilizers yog tus nqi qis tshaj ntawm tag nrho cov stabilizers, yog li txawm tias cov kev taw qhia tsis tu ncua ntawm cov stabilizers tshiab, txhuas ntsev stabilizers tseem tuav lub lag luam tseem ceeb rau stabilizers ib nrab xyoo tom qab;
2. Cov tshuaj toxicity ntawm cov hmoov lead ntsev stabilizers txwv nws daim ntawv thov nyob rau hauv ntau zaus nrog rau kev tu cev nruj;
3, tsis zoo dispersibility ntsev lead dispersibility yog tsis zoo, tab sis cov khoom tshiab launched nrog lubricants, los ntawm ib tug tej yam kev daws teeb meem ntawm dispersibility.
1. Kev txhim kho zoo heev ntawm kev sib xyaw thiab dispersing nrog cob;
2. Tsim nyog thiab ua tau zoo hauv thiab sab nraud lubrication collocation;
3. Kev tsim khoom thiab kev tswj xyuas zoo;
4. Thaum cov qauv sib xyaw, tus naj npawb ntawm lub sijhawm ntsuas tau yooj yim.
