Antistatic agents feem ntau muaj cov yam ntxwv ntawm surfactants, thiab muaj ob pawg polar thiab non-polar hauv lawv cov qauv. Feem ntau siv cov pawg polar (piv txwv li, pawg hydrophilic) suav nrog: anions ntawm carboxylic acid, sulfonic acid, sulfuric acid, thiab phosphoric acid, cations ntawm amine ntsev, quaternary ammonium ntsev, thiab -OH, -O- thiab lwm pab pawg. Feem ntau siv cov pawg uas tsis yog-polar pawg Kev sib deev (xws li lipophilic lossis hydrophobic pawg) suav nrog: pawg alkyl, alkaryl pawg, thiab lwm yam, yog li tsim tsib hom ASA feem ntau siv hauv kev lag luam fiber ntau, xws li amine derivatives, quaternary ammonium ntsev, sulfate esters. , thiab phosphoric acid esters thiab derivatives ntawm polyethylene glycol. Thaum ASA siv los ua txheej txheej, cov pab pawg hydrophobic yog adsorbed rau ntawm cov khoom siv, thiab txheej txheej txheej txheej txheej molecular ntawm ASA;
Thaum cov txheej txheem copolymerization siv los tsim cov fibers bicomponent, txheej txheej ASA molecular raug rhuav tshem, thiab sab hauv ASA tuaj yeem nkag mus rau hauv cov khoom nto; cov khoom nto muaj ib tug du ASA molecular txheej, thiab qhov txo nyob rau hauv qhov kev sib txhuam coefficient yuav txo tau lub sij hawm ntawm static hluav taws xob. Txawm li cas los xij, kev ntxuav ceev ntawm sab nraud ASA tsis zoo, yog li koj tuaj yeem xav txog kev siv cov tshuaj reactive los ua covalent bonds nrog fibers ntawm qhov kub thiab txias.
Sab nrauv ASA feem ntau yog coated nrog dej, cawv los yog lwm yam kuab tshuaj organic ua kuab tshuaj los yog dispersants. Cov pab pawg hydrophobic txuas nrog rau saum npoo ntawm cov khoom, thiab cov txheej txheem sab nrauv hydrophilic nqus cov dej noo nyob hauv ib puag ncig, vim tias dej muaj qhov dielectric siab tas li. Cov kua ua ib txheej conductive, thiab cov kab electrolyte uas muaj nyob rau hauv cov fibers kuj txo cov nto kuj mus rau ib tug tej yam; ASA siv nyob rau hauv fabrics feem ntau yog ib tug saturated ntev carbon saw cationic surfactant, uas yog yooj yim adsorbed thiab tsim vim tsis zoo hluav taws xob ntawm lub fiber nto. Moisture zaj duab xis, qhov dielectric tas li ntawm kev sib txhuam qhov sib txawv ntawm cov khoom kuj tseem txhim kho zoo; Yog tias ASA yog ib qho ionic compound, nws tus kheej muaj ionic conductivity. Kev faib tawm ntawm sab hauv ASA hauv cov polymer yog tsis sib xws. Thaum ntxiv rau ib qho nyiaj, qhov saum npoo ntawm cov khoom sib xyaw yuav tsim ib zaj duab xis nrog hydrophilic pawg txheej txheem sab nraud. Nyob rau tib lub sijhawm, sab hauv ASA tuaj yeem nkag mus rau saum npoo los ntxiv cov txheej txheem zaj duab xis. Yog li, kev sib raug zoo ntawm ASA thiab polymers tsim ob qhov sib txawv. Kev sib raug zoo zoo yuav ua rau qeeb tus nqi nkag mus rau saum npoo, ua rau nws nyuaj rau rov ua dua qhov poob ntawm ASA hauv lub sijhawm. Txwv tsis pub, cov khoom yuav poob nws cov kev tiv thaiv ntxov ntxov. Electrostatic zog.
