Antistatic Agent: Txoj Cai, Hom thiab Daim Ntawv Thov
I. Kev Taw Qhia
Hauv kev lag luam niaj hnub thiab lub neej niaj hnub, hluav taws xob zoo li qub yuav ua rau muaj ntau yam tsis yooj yim thiab muaj kev puas tsuaj. Antistatic agents, raws li ib yam khoom uas tuaj yeem txo lossis tshem tawm hluav taws xob zoo li qub, tab tom ua lub luag haujlwm tseem ceeb.
II. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov tshuaj antistatic
Kev ua haujlwm ntawm cov neeg ua haujlwm antistatic yog tsuas yog los txhim kho cov conductivity ntawm cov khoom nto, kom cov nqi zoo li qub tuaj yeem raug tshem tawm sai sai, yog li tiv thaiv cov tsub zuj zuj ntawm cov hluav taws xob zoo li qub. Feem ntau hais lus, cov tshuaj tiv thaiv kab mob tuaj yeem muab faib ua sab nraud thiab sab hauv. Cov tshuaj tiv thaiv sab nraud yog txuas rau saum npoo ntawm cov khoom los ntawm smearing, txau, thiab lwm yam los tsim cov txheej txheem conductive; Internal antistatic agents yog ntxiv thaum lub sij hawm tsim khoom ntawm cov khoom thiab tusyees dispersed nyob rau hauv cov khoom, kom cov khoom nws tus kheej muaj antistatic zog. Piv txwv li, thaum ntxiv cov tshuaj tiv thaiv kab mob rau polyolefins thiab npaj cov ntaub ntawv foaming los ntawm molding, tus neeg sawv cev antistatic tuaj yeem ua lub luag haujlwm hauv cov khoom, txo qhov tsis kam ntawm cov khoom, thiab tiv thaiv kev tsim thiab tsub zuj zuj ntawm hluav taws xob zoo li qub.
3. Hom tshuaj tiv thaiv kab mob
1. Anionic antistatic tus neeg sawv cev
- Hom tshuaj tiv thaiv kab mob no muaj anionic pawg hauv cov qauv molecular, xws li sulfonate, phosphate, thiab lwm yam. Lawv tuaj yeem raug adsorbed rau ntawm qhov chaw ntawm cov khoom thiab tshem tawm cov hluav taws xob zoo li qub los ntawm ionic conduction. Cov kev tshawb fawb tau pom tias cov khoom antistatic ntawm anionic antistatic cov neeg ua hauj lwm hauv cov fibers sib txawv muaj lawv tus yam ntxwv. Piv txwv li, hauv qee cov fibers, qhov ntom ntom ntom tuaj yeem txo tau sai.
2. Cationic antistatic agents
- Feem ntau yog quaternary ammonium ntsev cationic antistatic agents. Hom antistatic tus neeg sawv cev no muaj zoo adsorption thiab conductivity. Kev tsim khoom thiab kev siv quaternary ammonium ntsev cationic antistatic agents muaj qee yam kev txhim kho hauv tsev thiab txawv teb chaws. Piv txwv li, hauv kev lag luam textile, nws tuaj yeem siv los ua tus neeg sawv cev antistatic los txhim kho cov khoom antistatic ntawm cov ntaub. Ntxiv mus, los ntawm kev ntxiv cationic antistatic agents rau polypropylene resins rau blending thiab spinning, polypropylene fibers nrog antistatic zog tuaj yeem npaj rau zus tau tej cov BCF ntaub pua plag yarns thiab polypropylene multifilaments.
3. Nonionic antistatic agents
-Nonionic antistatic cov neeg ua haujlwm tsuas yog tso siab rau lawv tus kheej cov pab pawg hydrophilic kom cov av noo ntawm cov khoom nto, yog li txhim kho conductivity. Lawv muaj qhov cuam tshuam me me rau lub cev ntawm cov khoom siv thiab tsim nyog rau qee cov ntaub ntawv uas xav tau siab rau lub cev. Ntau hom nonionic antistatic cov neeg ua haujlwm muaj cov teebmeem antistatic sib txawv hauv cov fibers sib txawv. Cov kws tshawb fawb tau txuas ntxiv txhim kho kev siv cov tshuaj tiv thaiv kab mob los ntawm kev kawm txog cov teebmeem ntawm ntau hom tshuaj tiv thaiv kab mob (xws li anions, cations thiab nonionics) hauv fibers.
4. Amphoteric antistatic agents
- Amphoteric antistatic agents muaj cov yam ntxwv ntawm ob qho tib si anionic thiab cationic antistatic cov neeg ua haujlwm, tuaj yeem ua lub luag haujlwm antistatic hauv ntau qhov pH, thiab muaj kev hloov tau zoo.
IV. Daim ntawv thov teb ntawm cov tshuaj antistatic
1. Kev lag luam textile
- Hauv kev lag luam textile, antistatic agents tau siv dav hauv kev tsim cov khoom siv fiber ntau. Thaum cov feem ntau ntawm cov tshuaj tiv thaiv kab mob yog 0.6%, cov cuab yeej antistatic thiab ntxuav tsis kam ntawm cov fiber ntau zoo heev thiab ruaj khov. Piv txwv li, siv tus neeg sawv cev antistatic CAS thiab disperse dyes los kho polyester fabrics hauv tib da dej tuaj yeem ua tiav lub hom phiaj ntawm dyeing thiab antistatic tag tib lub sijhawm, txhim kho qhov hnav ntawm polyester fabrics, thiab txo cov teeb meem xws li plua plav nqus thiab hluav taws xob poob siab. los ntawm hluav taws xob zoo li qub thaum hnav thiab siv.
2. Cov khoom lag luam yas
- Ntxiv cov tshuaj tiv thaiv kab mob hauv cov txheej txheem tsim khoom ntawm cov khoom yas tuaj yeem tiv thaiv cov khoom yas los ntawm kev nqus plua plav thiab tsim cov hluav taws xob vim hluav taws xob zoo li qub thaum tsim khoom, kev thauj mus los thiab siv. Piv txwv li, nyob rau hauv zus tau tej cov polypropylene, antistatic polypropylene yog npaj los ntawm kev ntxiv antistatic agents, thiab cov teebmeem ntawm blending txoj kev thiab hnyav siv nyob rau hauv lub antistatic zog ntawm polypropylene yog kawm los txhim kho qhov zoo thiab kev ruaj ntseg ntawm cov khoom polypropylene. Kev xyaum tau ua pov thawj tias hauv kev tsim cov PVC nplaim-retardant conveyor txoj siv sia, los ntawm kev ntxiv cov tshuaj tiv thaiv kab mob thiab cov khoom siv hluav taws xob, cov khoom lag luam uas muaj cov nyhuv antistatic zoo tuaj yeem tsim ua kom tau raws li cov kev cai siv hauv ib puag ncig tshwj xeeb.
3. Kev lag luam Electronics
- Hauv kev tsim khoom, ntim khoom thiab kev thauj mus los ntawm cov khoom siv hluav taws xob, hluav taws xob zoo li qub tuaj yeem ua rau cov khoom siv hluav taws xob puas. Cov tshuaj tiv thaiv kab mob tuaj yeem siv rau hauv cov khoom ntim rau cov khoom siv hluav taws xob, xws li cov thawv ntim khoom yas, thiab lwm yam, los tiv thaiv cov khoom siv hluav taws xob los ntawm hluav taws xob zoo li qub.
V. Xaus
Antistatic agents ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, kev ua tau zoo ntawm cov neeg ua haujlwm antistatic kuj tseem nce ntxiv, xws li yuav tsum tau ua kom zoo dua qub thiab qis dua tus nqi ntxiv kom ua tiav cov nyhuv antistatic zoo. Nyob rau hauv lub neej yav tom ntej, kev tshawb fawb thiab kev loj hlob ntawm antistatic cov neeg sawv cev yuav tsim nyob rau hauv ib tug ntau npaum li cas, environmentally friendly thiab multifunctional kev taw qhia kom tau raws li kev loj hlob ntawm cov kev xav tau ntawm ntau industries.
