Mapangidwe a maselo a antistatic agent amakhala ndi gawo losamba komanso gawo la hydrophilic ndi antistatic.
[1]. Pochiza nsalu za polyester, gawo la hydrophilic limachokera ku gawo la unyolo wa polyether, ndipo gawo losamba limachokera ku mapangidwe a filimu a gawo la polyester chain ndi polima lonse. Mapangidwe a molekyulu a polyester chain segment ndi ofanana ndi a polyester. Pambuyo pa chithandizo cha kutentha, eutectic imapangidwa ndipo imakhala mu fiber, yomwe imathandizira kwambiri kusungunuka. Kutalikirapo kwa gawo la unyolo wa ma molekyulu, kukula kwake kwa molekyulu yokulirapo, ndikosavuta kuchapa. Pogwiritsidwa ntchito pazinthu zapulasitiki, njira yowonjezera mkati imagwiritsidwa ntchito. Malingana ngati maziko a hydrophilic ndi maziko a oilphilic akuphatikizidwa bwino, chowonjezera cha antistatic sichimangokhalira kugwirizanitsa ndi pulasitiki, komanso imatha kuyamwa madzi mumlengalenga, ndikusewera antistatic effect. Mwa kuyankhula kwina, ma ion a antistatic agent amagawidwa mosiyanasiyana mkati mwa utomoni, ndi ndende yapamwamba komanso yotsika kwambiri yamkati, monga momwe tawonetsera pa Chithunzi 1. Antistatic action makamaka imadalira gawo la monomolecular lomwe limagawidwa pamtunda. Uv chitetezo nsalu utomoni ndi antistatic zowonjezera kuchiritsa pamodzi monga momwe chithunzi 2opanga nsalu zoletsa moto
[2], magulu a hydrophilic a antistatic agents amakonzedwa ku mbali ya mpweya, ndipo madzi mumlengalenga amakongoletsedwa ndi magulu a hydrophilic kuti apange gawo limodzi loyendetsa maselo. Pamene antistatic monomolecular wosanjikiza pamwamba pa utomoni kuwonongeka chifukwa cha mikangano, kutsuka ndi zifukwa zina, ndi ntchito antistatic yafupika, ndi antistatic wothandizila mamolekyulu mkati utomoni kupitiriza kusamukira kumtunda, kotero kuti pamwamba chilema cha monomolecular. wosanjikiza ukhoza kusinthidwa kuchokera mkati. Kutalika kwa nthawi yofunikira pakubwezeretsa katundu wa antistatic kumadalira kusamuka kwa mamolekyu a antistatic mu utomoni ndi kuchuluka kwa antistatic wothandizila anawonjezera, ndi kusamuka kwa antistatic wothandizila zikugwirizana ndi galasi kusintha kutentha kwa utomoni, ngakhale ngakhale. wa antistatic wothandizira ndi utomoni ndi wachibale molekyulu wolemera wa antistatic wothandizira. Pamenepo,opanga nsalu zoletsa motonsalu zopangidwa ndi ulusi wamankhwala, zopangidwa ndi pulasitiki zimakhala ndi gawo lina la kutchinjiriza, zida zilizonse zotchingira, kutayikira kwake kosasunthika kuli ndi njira ziwiri, imodzi ndi pamwamba pa insulator, inayo ndi insulator mkati. Zakale zimagwirizana ndi kukana kwapamwamba ndipo zotsirizirazo zimatsutsana ndi thupi. Kwa mapulasitiki ndi nsalu, magetsi ambiri osasunthika amatuluka kuchokera pamwamba, zoyesera zatsimikizira kuti lamulo lofananalo limagwira ntchito kwa insulators.opanga nsalu zoletsa moto
[3] Njira yogwiritsira ntchito zoletsa moto ndizovuta, koma cholinga chodula kuzungulira kuyaka kumatheka kudzera munjira zamakina ndi zakuthupi. Mu kuyaka kwa lawi retardant multifunctional gulu nsalu mapulasitiki ndi nsalu CHIKWANGWANI nsalu, ndi zachiwawa anachita pakati mpweya unyolo ndi mpweya, pa dzanja limodzi, organic kosakhazikika mafuta kwaiye, ndipo nthawi yomweyo, ambiri yogwira hydroxyl. radical HO imapangidwa. Ma chain reaction of free radicals amapangitsa kuti lawi likhale loyaka. Antimony okusayidi ndi bromine pawiri lawi retardant ndi peroxide ufulu ankafuna kusintha zinthu mopitirira intiators kulimbikitsa m'badwo wa bromine ufulu ankafuna kusintha zinthu mopitirira muyeso kutentha, m'badwo wa antimoni bromidi, amene ndi kosakhazikika mpweya mankhwala, osati mwamsanga kuyamwa umuna wa zinthu zoyaka; kuchepetsa kuchuluka kwa zinthu zomwe zimayaka, komanso zimatha kugwira ma radicals a HO, kupewa kuyaka, kuti mukwaniritse bwino nsalu yotchinga moto.
