Polymerisation no gutunganya PTFE

Monomer wa PTFE ni tetrafluoroethylene (TFE), naho aho itetse ni dogere selisiyusi 76.3.Iraturika cyane imbere ya ogisijeni kandi irashobora kugereranywa nimbunda.Kubwibyo, umusaruro wacyo, kubika no gukoresha mu nganda bisaba uburinzi bukomeye, ibisohoka nabyo bigomba kugenzurwa, nabyo bikaba bimwe mubisoko nyamukuru byigiciro cya PTFE.Ubusanzwe TFE ikoresha polymerisiyasi yubusa yubusa mu nganda, ikoresheje persulfate nkuwatangije, ubushyuhe bwa reaction burashobora kuba hagati ya dogere selisiyusi 10-110, ubu buryo bushobora kubona uburemere buke cyane bwa PTFE (ndetse bushobora kuba burenga miliyoni 10), nta munyururu ugaragara ihererekanyabubasha.

Kubera ko gushonga kwa PTFE ari hejuru cyane, ikaba yegereye ubushyuhe bwangirika, kandi ubwinshi bwa molekile yayo ntabwo ari nto, ntibishoboka ko umuntu agera ku gipimo cyiza cyo gushonga yishingikirije gusa ku bushyuhe nka polimeri isanzwe ya termoplastique.Nigute kaseti ya Teflon cyangwa Teflon ikorwa?Kubijyanye no kubumba, ifu ya PTFE isukwa mubibumbano, hanyuma igashyuha hanyuma igashyirwaho igitutu kugirango ifu.Niba hakenewe gusohora, ibice bya hydrocarubone bigomba kongerwaho PTFE kugirango bifashe gukurura no gutemba.Ingano yibi bikoresho bya hydrocarubone igomba kugenzurwa murwego runaka, bitabaye ibyo biroroshye gutera umuvuduko ukabije cyangwa ibicuruzwa byarangiye.Nyuma yuburyo bwifuzwa, ibice bya hydrocarubone bivanwaho no gushyuha gahoro, hanyuma bigashyuha hanyuma bigahinduka ibicuruzwa byanyuma.

Imikoreshereze ya PTFE
Bumwe mu buryo bukoreshwa bwa PTFE ni nk'igifuniko.Uhereye ku isafuriya ntoya idafite inkoni murugo kugeza kurukuta rwinyuma rwa cube yamazi, urashobora kumva ingaruka zubumaji ziyi kote.Ibindi bikoreshwa ni ugufunga kaseti, kurinda insinga zo hanze, igipimo cyimbere cyimbere, ibice byimashini, ibikoresho bya laboratoire, nibindi. Niba ukeneye ibikoresho byakoreshwa mubihe bibi, noneho ubitekerezeho, birashobora kugira ibisubizo bitunguranye.
