Uma kuqhathaniswa nezinye izinto zokwakha, amapulasitiki anezimpawu zokusebenza ezinhlanu ezilandelayo:
Isisindo esilula: Ipulasitiki iyinto elula enokusabalalisa kokuminyana okuhlobene phakathi kuka-0.90 no-2.2.Ngakho-ke, kungakhathaliseki ukuthi ipulasitiki ingantanta emanzini, ikakhulukazi ipulasitiki enegwebu, ngenxa yama-micropores akuwo, ukuthungwa kulula, futhi ukuminyana kwesihlobo ku-0.01 kuphela.Le ndawo ivumela amapulasitiki ukuthi asetshenziswe ekukhiqizeni imikhiqizo edinga isisindo esincishisiwe.
Ukuzinza kwamakhemikhali okuhle kakhulu: Amapulasitiki amaningi anokumelana nokugqwala okuhle kumakhemikhali anjengama-asidi nama-alkali.Ikakhulukazi i-polytetrafluoroethylene (F4) ngokuvamile eyaziwa ngokuthi inkosi yamapulasitiki, ukuzinza kwayo kwamakhemikhali kungcono nakakhulu kunegolide, futhi ngeke kubi uma ibiliswa ku-“aqua regia” amahora angaphezu kweshumi.Ngenxa yokuthi i-F4 inokuzinza okuhle kakhulu kwamakhemikhali, iyinto efanelekile ukumelana nokugqwala, njenge-F4 ingasetshenziswa njengempahla yokudlulisa amapayipi oketshezi olubolayo kanye ne-viscous.
Ukusebenza kahle kokufakwa kukagesi kagesi: Amapulasitiki ajwayelekile angabaqhubi abampofu bakagesi, futhi ukumelana kwawo kwendawo nokumelana nevolumu kukhulu kakhulu, okungavezwa ngezinombolo kuze kufike ku-109-1018 ohms.I-voltage yokuhlukana inkulu, futhi inani le-tangent lokulahlekelwa kwe-dielectric lincane.Ngakho-ke, amapulasitiki anezinhlobonhlobo zezicelo ezimbonini zikagesi nezemishini.
Ama-conductor okushisa aphansi anomphumela wokunciphisa umsindo nokumuncwa kokushaqeka: Ngokuvamile, ukuqhutshwa kokushisa kwamapulasitiki kuphansi, kulingana ne-1/75-1/225 yensimbi., ukungezwani kahle komsindo nokumelana nokushaqeka.Mayelana nokufakwa kwe-thermal, amafasitela epulasitiki yengilazi eyodwa aphakeme ngo-40% kunamafasitela engilazi eyodwa ye-aluminium, futhi amafasitela engilazi amabili aphezulu ngo-50%.Ngemuva kokuthi iwindi lepulasitiki lihlanganiswe nengilazi yokushisa, lingasetshenziswa ezindaweni zokuhlala, izakhiwo zamahhovisi, izigceme namahhotela, ukonga ukushisa ebusika nokugcina izindleko zomoya ehlobo, futhi izinzuzo zisobala kakhulu.
Ukusatshalaliswa okubanzi kwamandla emishini namandla athile aphezulu: amanye amapulasitiki aqinile njengetshe nensimbi, kanti amanye athambile njengephepha nesikhumba;ngokombono wezakhiwo zemishini ezinjengobulukhuni, amandla aqinile, ukunwebeka namandla okuthinta amapulasitiki, ububanzi bokusabalalisa Okubanzi, kunendawo enkulu yokuzikhethela.Ngenxa ye-gravity encane ethile namandla aphezulu epulasitiki, inamandla athile aphezulu.Uma kuqhathaniswa nezinye izinto, amapulasitiki nawo anamaphutha asobala, njengokushiswa kalula, hhayi ukuqina okuphezulu njengezinsimbi, ukungakwazi ukumelana nokuguga, nokungazweli ukushisa.
