Teflon VS Nylon, Ni irihe tandukaniro?

Kugenda mwisi yisi ya plastike ikora cyane nka Teflon PTFE irashobora kugutera hagati yimpaka nka 'nylon vs teflon ' cyangwa 'delrin vs teflon. ' Dore inzira yihuse igufasha kunyuramo.

Teflon, izina ryirango dukesha Chemours, iragaragara mubantu. Azwi kandi nka Polytetrafluoroethylene (PTFE), ibi bikoresho byerekana iyo bigeze ku kurwanya imiti no guhangana n'ubushyuhe bwinshi. Tekereza plastike idashonga byoroshye - Teflon PTFE yishimira ko ishonga rya 327 ° C (620 ° F)! Ibi bituma ihitamo akazi gakomeye gasaba ituze mubihe byumuriro.

Ariko rindira, haribindi. Teflon ntabwo ivanga n'imiti. Iguma irwanya, ikagira uruhare rukomeye mubikorwa byo gukora, cyane cyane mukubyara ibintu nka gaseke na bombo. Wibuke imbaraga za dielectric ya 60 kV / mm? Niyo mpamvu amashanyarazi akunda guhitamo Teflon.

Urashobora kumva abantu bavuga kubyerekeranye na 'ijosi rikomeye.' Iranyerera mubisabwa aho ubuso butari inkoni bugomba, tekereza kubikoresho byawe bitari inkoni mugikoni.

Ariko, mugihe ugumye mubiganiro teflon vs nylon 'cyangwa ' ptfe vs nylon ', tekereza kuri ibi: Buri mushinga ukeneye intwari yawo. Teflon irashobora kuba idakomeye kandi ntishobora kwihanganira ubushyuhe, ariko byakwiranye nibisabwa bikenera guhuza? Birashoboka ko atari byo.

Guhitamo plastike iboneye, yaba iyo kunyura muri 'nylon vs teflon ' cyangwa gushakisha 'delrin ubushyuhe bwo kurwanya, ' bisobanura guhuza imiterere yihariye yibikoresho, nkimbaraga zingutu hamwe nubukanishi, hamwe nibyifuzo byumushinga wawe.

Mubyukuri, mugihe Teflon PTFE itangaje hamwe nubushyuhe bwayo hamwe nubusembure bwimiti, ibyifuzo byumushinga wawe bigomba kuyobora amahitamo yawe. Byose bijyanye no guhuza ibikenewe hamwe nibintu. Hitamo neza, kandi umushinga wawe uzagushimira!

Nylon: Paragon yimbaraga zikomeye kandi ziramba

Gutangira urugendo ruzenguruka isi ya plastiki bituzanira imbonankubone na Nylon. Intangarugero mu nganda za plastiki, kuramba no gukomera kwinshi, guhindagurika hagati ya MPa 75-120, ikazamura ikamenyekana cyane.

Yavutse mubitekerezo bya Wallace Carothers, iyi nylon polymer ntabwo igaragara gusa; induru. Akenshi iboneka mubice byubukanishi nka gare, ibihuru, hamwe nu biti, byerekana imiterere yubukanishi kandi bikambara birwanya ubwibone. Cyane cyane iyo ibiganiro bihindagurika hagati ya 'nylon vs teflon ' cyangwa 'nylon vs delrin, ' Nylon yigaragaza cyane mubikorwa byo gutunganya no gucapa 3D, bitewe nubushobozi ifite bwo kurwanya kwambara.

Ariko, buri ntwari igira akajagari. Kuri Nylon, ni urukundo rwayo kubushuhe. Gukuramo kugeza kuri 1,2% yuburemere bwayo mumazi mugihe ushizemo amasaha 24, uyu mutungo udasanzwe urashobora kugoreka ubunini nubunini, bikagira ingaruka kumurongo wacyo ahantu hatose. Mugihe rero, mugihe dutekereza kuri 'birakomeye, nylon cyangwa teflon, ' nibyingenzi kumenya ko mubidukikije bikunze kwibasirwa nubushuhe, Nylon ishobora kwerekana impinduka zoroshye.

Nyamara, ntugahungabanye rwose nimpaka za 'ptfe vs nylon ' utiriwe wemera ko Nylon ihindagurika. Kuva imyenda kugeza kubumba inshinge, guhuza n'imihindagurikire yayo bishimangira kwizerwa mu nganda zitandukanye. Mugereranije, ibintu nka 'delrin ubushyuhe bwo kurwanya ' cyangwa 'teflon ptfe ' imiterere yimiti irashobora gufata umwanya mubikorwa bimwe na bimwe, bigatuma buri kintu, Nylon kirimo, kibona ahantu ibintu byihariye birabagirana cyane.

Wibuke, guhitamo ibikoresho, haba hagati ya 'nylon vs teflon ' cyangwa birenze, bizenguruka guhuza ibyifuzo byumushinga nimbaraga zumubiri. Nylon, nimbaraga zayo zikomeye hamwe na kamere irwanya kwambara, rwose irwanya porogaramu nyinshi, mugihe ubushuhe bwayo bwabazwe. Hindura amahitamo yawe neza, kandi urebe imishinga yawe itera imbere!

Delrin (POM): Apex yo Kwinangira gukomeye no guhagarara neza

Reka dusuzume ubushakashatsi bwacu twibira mu isi ya Delrin, izina ryirango riba inkuru yaryo murwego rwa thermoplastique, neza na polyoxymethylene (POM).

Delrin yerekana ibyangombwa byayo hamwe no gukomera gukomeye, guhagarara neza kurwego, hamwe nubushyuhe buke. Bitekerezeho nkibikoresho byizewe, cyane cyane mugihe ukeneye ikintu gifite umugongo wibice bya mashini bitewe nuburinganire bwacyo buhanitse hamwe nimbaraga zingana zibyina hagati ya 69-79 MPa. Uru ruvange rwubwiza bwumubiri rutuma rukundwa mubintu bisaba kuvanga ibintu neza kandi bikomeye.

Kugereranya 'delrin vs nylon ' akenshi bivuka, cyane cyane mubucuti bwabo nubushuhe. Shira Delrin mumasaha 24 kandi ikuramo 0.25% gusa yubushuhe, bikabigira intangarugero mugihe imbyino yibikoresho hamwe nubushuhe irimo gukina, kandi igatwikira Nylon mumishinga aho ubuhehere bugira uruhare runini.

Mubihe bisaba ibikoresho bifite imiterere ihamye, cyane cyane mubikorwa byo gutunganya, Delrin arazamuka. Ubushuhe bwacyo buke hamwe no guhora mubipimo bituma bugaragara, akenshi bugashyirwa kuntebe mugihe impaka za 'nylon vs delrin '.

Birakwiye ko tumenya ko nubwo ETFE na PTFE byombi ari umuryango wa fluoropolymer, imigani yabo yo gukora iratandukanye. Kumenya inkuru zibyara umusaruro byerekana imikorere yabo n'inzira zo gukoresha.

Muri make, mugihe 'delrin vs teflon ' cyangwa 'nylon vs teflon ' ibiganiro bishobora kuguhindura, wibuke: byose ni uguhuza imiterere yihariye yibikoresho, nkimbaraga za Delrin nubukanishi bwo kwambara, hamwe numushinga wawe ukeneye. Nurufunguzo rwo gukingura umuryango wisi aho imishinga yawe itagerwaho gusa; barusha abandi. Hitamo neza rero, kandi imishinga yawe itere imbere iteka!

Aokai ni a umwuga wumwuga wibikoresho bya PTFE , dutanga ibicuruzwa birimo Imyenda ya PTFE, Kaseti ya PTFE, Umukandara wa PTFE, nibindi, jya mubicuruzwa byacu kugirango wige byinshi, cyangwa vugana nitsinda ryacu , twishimiye cyane kuguha ubufasha.
