Uhlalutyo lwe-Mechanism lwabavelisi be-antistatic flame retardant

Ulwakhiwo lwemolekyuli ye-agent ye-antistatic iquka inxalenye ehlambekayo kunye ne-hydrophilic kunye ne-antistatic part.

 

[1]. Kunyango lwamalaphu e-polyester, inxalenye ye-hydrophilic ivela kwi-polyether chain chain segment, kwaye inxalenye ehlambekayo ivela kwifilimu yokwenziwa kwecandelo le-polyester chain kunye ne-polymer yonke. Isakhiwo se-molecular yecandelo le-polyester chain ifana ne-polyester. Emva kokunyanga ukushisa, i-eutectic yenziwe kwaye iqulethwe kwifiber, ephucula kakhulu ukuhlamba. Okukhona icandelo letsheyina lemolekyuli lide, kokukhona lilikhulu ubunzima bemolekyuli, kokukhona ukuhlambeka kubhetele. Xa isetyenziselwa iimveliso zeplastiki, indlela yokongeza yangaphakathi isetyenziswa. Ngethuba nje isiseko se-hydrophilic kunye nesiseko se-oilphilic zidibaniswe ngokufanelekileyo, isongezelelo se-antistatic asigcini nje ukugcina ukuhambelana okuthile kwiplastiki, kodwa sinokufunxa amanzi emoyeni, kwaye sidlale umphumo we-antistatic. Ngamanye amazwi, i-ion yale arhente ye-antistatic isasazwa ngokungalingani ngaphakathi kwe-resin, kunye noxinzelelo oluphezulu lwe-surface kunye ne-concentration yangaphakathi ephantsi, njengoko kuboniswe kuMzobo 1. Isenzo se-antistatic sixhomekeke ikakhulu kwi-monomolecular layer isasazwa kwi-resin surface. I-resin yelaphu lokukhusela i-Uv kunye ne-antistatic additives ephilisa kunye njengoko kubonisiwe kuMfanekiso 2abavelisi belaphu abangafuni mlilo

[2], amaqela e-hydrophilic ee-antistatic alungelelaniswe kwicala lomoya, kwaye amanzi emoyeni adsorbed ngamaqela e-hydrophilic ukwenza umaleko omnye we-molecular conductive. Xa umaleko we-antistatic monomolecular kumphezulu we-resin wonakaliswe ngenxa yokukhuhlana, ukuhlanjwa kunye nezinye izizathu, kunye nokusebenza kwe-antistatic kuncitshisiwe, iimolekyuli ze-antistatic arhente ngaphakathi kweresin ziyaqhubeka nokufudukela kumphezulu, ukuze isiphene somphezulu we-monomolecular. umaleko unokutshintshwa ukusuka ngaphakathi. Ubude bexesha elifunekayo ukubuyiswa kweempawu ze-antistatic kuxhomekeke kwisantya sokufuduka kweemolekyuli ze-antistatic kwi-resin kunye nenani le-agent ye-antistatic eyongeziweyo, kunye nesantya sokufuduka kwe-agent ye-antistatic ihambelana nobushushu beglasi benguqu ye-resin, ukuhambelana. ye-agent ye-antistatic kunye ne-resin kunye nobunzima be-molecular agent ye-antistatic agent. Inyaniso,abavelisi belaphu abangafuni mliloAmalaphu eekhemikhali zefiber, iimveliso zeplastiki zinenqanaba elithile lokugquma, nayiphi na imathiriyeli yokugquma, ukuvuza kwayo okumileyo kuneendlela ezimbini, enye ingumphezulu we-insulator, enye yi-insulator ngaphakathi. Eyangaphambili inxulumene nokumelana nomphezulu kunye nokugqibela ukuxhathisa umzimba. Kwiiplastiki kunye namalaphu, uninzi lokuvuza kombane ongatshintshiyo ukusuka kumphezulu, iimvavanyo ziye zangqina ukuba umthetho ofanayo uyasebenza kwii-insulators.abavelisi belaphu abangafuni mlilo

 

[3] Indlela yokusebenza ye-flame retardants iyinkimbinkimbi, kodwa injongo yokunqumla umjikelezo wokutsha ifezekiswa ngeendlela zekhemikhali kunye nezomzimba. Ekutshisweni kwelaphu lelangatye elibuyisela izinto ezininzi zeplastiki kunye nelaphu lefayibha yemichiza, kunye nesenzo sobundlobongela phakathi kwetsheyini yekhabhoni kunye neoksijini, kwelinye icala, i-organic volatile fuel yenziwa, kwaye kwangaxeshanye, inani elikhulu le-hydroxyl esebenzayo kakhulu. radical HO yenziwa. Itsheyini yokusabela kweeradicals zasimahla igcina idangatye livutha. I-Antimony oxide kunye ne-bromine compound flame retardant kunye ne-peroxide free radical Initiators ikhuthaza ukuveliswa kwe-bromine free radical phantsi kwesenzo sobushushu, isizukulwana se-antimony bromide, esisisixhobo segesi esiguquguqukayo, asikwazi ukufunxa ngokukhawuleza ukukhutshwa kwezinto ezivuthayo, nciphisa ukuxinana kwezinto ezitshayo, kodwa unokubamba i-HO simahla iiradicals, ukuthintela ukutsha, ukufezekisa isiphumo esingcono selaphu le-flame retardant.
