PTFE Gutunganya no Gushyira mu bikorwa

NikiPTFE?

Reka dutangire ubushakashatsi kubyo PTFE aribyo.Kuyiha ni umutwe wuzuye, polytetrafluoroethylene ni polymer synthique igizwe nibintu bibiri byoroshye;karubone na fluor.Bikomoka kuri tetrafluoroethylene (TFE) kandi bifite imitungo yihariye ituma iba ibikoresho byingirakamaro mubikorwa byinshi.Urugero:

Ahantu ho gushonga cyane: Hamwe no gushonga hafi ya 327 ° C, haribintu bike cyane aho PTFE yangizwa nubushyuhe.

Hydrophobique: Kurwanya amazi bivuze ko itigera itose, ikagira akamaro muguteka, kwambara ibikomere nibindi.

Imiti ya inert: Ubwinshi bwumuti nimiti ntabwo byangiza PTFE.

Coefficient nkeya yo guterana: Coefficient de friction ya PTFE nimwe murwego rwo hasi mubintu byose bibaho, bivuze ko ntakintu kizakomeza.

Imbaraga zo hejuru cyane: Nubushobozi bwo kunama no guhindagurika, nubwo haba hari ubushyuhe buke, bivuze ko bushobora gukoreshwa muburyo butandukanye butabuze ubunyangamugayo.

Gutunganya PTFE

PTFE irashobora kuboneka muburyo bwa granular, gutatanya nuburyo bwiza bwifu.Semi-kristalline PTFE ifite ubushyuhe bwinshi bwo gushonga no gushonga ibishishwa, bigatuma gusohora no gutera inshinge bigoye.Gutunganya PTFE rero, birasa cyane no gutunganya ifu kuruta iya plastiki gakondo.

Granular PTFE ikorwa mumazi ashingiye kumazi polymerisation reaction.Ibisigazwa bya granular resin akenshi bitunganyirizwa muburyo bwo guhunika.Ibicuruzwa byoherejwe na PTFE byakozwe muburyo busa, hiyongereyeho ibikoresho byo gukwirakwiza.Ibicuruzwa bitatanye birashobora gukoreshwa muburyo bwa PTFE cyangwa birashobora gutunganyirizwa muri firime yoroheje ukoresheje firime.Ifu ya PTFE ikorwa muri emulsion polymerisation reaction.Ifu nziza yavuyemo irashobora gushirwa muma kaseti ya PTFE, igituba cya PTFE, hamwe no kubika insinga, cyangwa gukoreshwa nkinyongera kugirango wongere imbaraga zo kwangirika mubindi bikoresho bya polymeriki.

Porogaramu 5 yambere ya PTFE

1. Gukoresha imiti irwanya ruswa

Rubber, ikirahure, ibyuma bivangwa nibindi bikoresho binanirwa kubahiriza ibihe bibi byubushyuhe, umuvuduko hamwe nibitangazamakuru bya chimique bibana bitewe nubusembwa bwabo mukurwanya ruswa.Nyamara, PTFE ifite imbaraga zo kurwanya ruswa bityo ikaba yarahindutse ibikoresho nyamukuru birwanya ruswa kuri peteroli, imiti, imyenda nizindi nganda.

2. Gushyira mu bikorwa ibintu byo guterana amagambo mu mutwaro

Gusiga amavuta ntibikwiye kubice byo guteranya ibikoresho bimwe na bimwe, kubera ko amavuta yo gusiga ashobora gushonga nuwashonga kandi ntakora, cyangwa ibicuruzwa mumiti yimiti, ibiryo, imyenda nizindi nganda bigomba kwirinda kwanduzwa namavuta.Kubera iyo mpamvu, plastike ya PTFE, coefficente yo guterana iri munsi yibindi bikoresho bizwi, byahindutse ibikoresho byiza cyane byo gusiga amavuta (bitwara imitwaro itaziguye) yibikoresho bya mashini.

3. Gusaba amashanyarazi na elegitoroniki

Igihombo gito hamwe na dielectric ntoya ihoraho yibikoresho bya PTFE ituma ishobora gukorwa mumigozi yometse kuri moteri ya moteri, thermocouples nibikoresho byo kugenzura.Filime ya PTFE nigikoresho cyiza cyo gukingira ibikoresho, gukora radiyo yerekana insinga, insinga zidafite insinga, moteri na transformateur, kandi ni kimwe mubikoresho byingirakamaro mu kirere no mubindi bikoresho bya elegitoroniki.

4. Gusaba ubuvuzi

Kwagura PTFE ni inert gusa kandi ihuza na biologiya cyane, ntabwo rero itera kwangwa numubiri, nta ngaruka mbi zifatika kumubiri wumuntu, irashobora guhindurwa muburyo ubwo aribwo bwose, kandi ifite imiterere-mikorobe myinshi.

5. Gukoresha imiti igabanya ubukana

Hamwe n'ubuso buke bwo hejuru bwibintu byose bikomeye, PTFE Teflon ntabwo ifatanye nibintu byose.Byongeye kandi, ifite imbaraga zo guhangana nubushyuhe bwo hejuru kandi buke.Nkigisubizo, yakoreshejwe cyane muburyo bwo kurwanya ibifunga ibikoresho bidafite inkoni.
