I-Extrusion of Plastics - Isimiso Esisebenzayo kanye Nemingcele Yenqubo
I-Extrusion iyinqubo yokukhiqiza umthamo ophezulu.Impahla yepulasitiki iyancibilika ngokufakwa kokushisa futhi ikhishwe nge-die ibe yisimo oyifunayo.Isikulufu esijikelezayo esiyicylindrical sifakwa ngaphakathi emgqonyeni esiphoqa ukuthi kukhishwe impahla yepulasitiki encibilikisiwe ngedayizi.Impahla enwetshiwe ithatha...Funda kabanzi -
Inqubo Yokukhiqiza ye-PTFE
I-Tetrafluoroethylene yalungiswa okokuqala ngo-1933. I-synthesis yamanje yezohwebo isekelwe ku-fluorspar, i-sulfuric acid ne-chloroform.Inqubo Yokukhiqiza Eyisisekelo ye-PTFE Polymer: Ukwenziwa Kwe-PTFE Polymer/Resin ngokuyisisekelo kwenziwa ngezigaba ezimbili.Okokuqala, i-TFE Monomer ngokuvamile isetshenziswa...Funda kabanzi -
Ukukhishwa kwama-polymers
I-Extrusion iyinqubo yokukhiqiza imikhiqizo emide ye-cross-section engaguquki (izinduku, amashidi, amapayipi, amafilimu, i-insulation coating) ephoqelela ukuthambisa i-polymer ngokusebenzisa ifa elinembobo.Izinto ze-polymer ngendlela yama-pellets zifakwa ku-extruder nge-hopper.Impahla ithi...Funda kabanzi -
I-Polyether ether ketone (PEEK) Izakhiwo Nezinhlelo zokusebenza
I-Polyether ether ketone (PEEK) i-polymer ye-organic thermoplastic engenambala emndenini we-polyaryletherketone (PAEK), esetshenziswa ezinhlelweni zobunjiniyela.Yaqala yethulwa yi-Victrex PLC, kwase kuba yi-Imperial Chemical Industries (ICI) ekuqaleni kwawo-1980.Izakhiwo: I-PEEK iyi-semicrystalline th...Funda kabanzi -
Izicelo ze-Polymer Adsorption
I-Adsorption ukunamathela kwama-ion noma ama-molecule phezu kwesinye isigaba.I-Adsorption ingenzeka nge-physisorption kanye ne-chemisorption.Ama-ion nama-molecule angakhanga ezinhlotsheni eziningi zezindawo ezihlanganisa izindawo ze-polymer.I-polymer iyi-molecule enkulu eyakhiwe amayunithi aphindaphindayo aboshwe ukuze...Funda kabanzi -
I-polymer adsorption
I-Adsorption ukunamathela kwama-ion noma ama-molecule ebusweni besinye isigaba.I-Adsorption ingase yenzeke nge-physisorption kanye ne-chemisorption.Ama-ion nama-molecule angakhanga ezinhlotsheni eziningi zezindawo ezihlanganisa izindawo ze-polymer.I-polymer iyi-molecule enkulu eyakhiwe amayunithi aphindaphindayo aboshwe ndawonye...Funda kabanzi
