Teflon VS Nylon, Pali Kusiyana Kotani?

Kuyenda m'dziko la mapulasitiki apamwamba kwambiri ngati Teflon PTFE akhoza kukuponyerani pakati pa zokambirana monga 'nayiloni vs teflon' kapena 'delrin vs teflon.' Nayi chitsogozo chachangu chokuthandizani kuti mudutse.

Teflon, dzina lachidziwitso lomwe tili nalo kwa Chemours, likuwonekera pagulu. Zomwe zimadziwikanso kuti Polytetrafluoroethylene (PTFE), izi zimawonetsa kukana kwa mankhwala komanso kupirira kutentha kwambiri. Tangoganizani pulasitiki yomwe simasungunuka mosavuta - Teflon PTFE imadzitamandira ndi malo osungunuka a 327 ° C (620 ° F)! Izi zimapangitsa kuti ikhale yosankhika kwambiri pantchito zomwe zimafuna bata pamikhalidwe yamoto.

Koma dikirani, pali zambiri. Teflon samasakanikirana ndi mankhwala. Imakhala yosasunthika, ndikupangitsa kukhala wosewera wamphamvu pantchito yopanga, makamaka popanga zinthu monga ma gaskets ndi ma bearings. Kumbukirani mphamvu yake ya dielectric ya 60 kV/mm? Ndicho chifukwa chake kusungunula magetsi nthawi zambiri kumasankha Teflon.

Mutha kumva anthu akulankhula za 'khosi lolimba' la Teflon. Ngakhale kuuma kwakeko, kukangana kwake kochepa, komwe kumakhala pakati pa 0.05-0.10, ndikosintha. Imalowa m'mapulogalamu omwe malo osamata ndi oyenera, ganizirani za mapoto anu osamata kukhitchini.

Komabe, mukakhala mumakambirano a 'teflon vs nayiloni' kapena 'ptfe vs nayiloni' ganizirani izi: Ntchito iliyonse imafunikira ngwazi yakeyake. Teflon ikhoza kukhala yopanda ndodo komanso yosasunthika kutentha, koma ingagwirizane ndi mapulogalamu omwe amafunikira zomatira? Mwina ayi.

Kusankha pulasitiki yoyenera, kaya ndikudutsa mu 'nayiloni vs teflon' kapena kufufuza 'kukana kutentha kwa delrin,' kumatanthauza kugwirizanitsa mawonekedwe apadera a zinthu, monga mphamvu zamakina ndi makina, ndi zosowa za polojekiti yanu.

Kwenikweni, pamene Teflon PTFE ikuwoneka bwino ndi kukana kutentha ndi kuzizira kwa mankhwala, zofuna za polojekiti yanu ziyenera kuwongolera kusankha kwanu. Zonse zimatengera kufananiza zosowa ndi katundu. Sankhani mwanzeru, ndipo polojekiti yanu ikuthokozani!

Nylon: Paragon of High Tensile Strength and Durability

Kuyamba ulendo wodutsa dziko la mapulasitiki kumatibweretsera maso ndi maso ndi Nayiloni. Wolimba m'makampani apulasitiki, kulimba kwake komanso kulimba kwamphamvu kwambiri, kugwedezeka pakati pa 75-120 MPa, kumamukweza pamalo odziwika bwino.

Wobadwa kuchokera m'malingaliro a Wallace Carothers, polima wa nayiloni uyu samangowonekera; imafuula kwenikweni. Nthawi zambiri amapezeka m'zigawo zamakina monga magiya, ma bushings, ndi ma bearings, amawonetsa mawonekedwe ake amakina komanso kukana monyada. Makamaka pamene zokambirana zasinthana pakati pa 'nayiloni vs teflon' kapena 'nayiloni vs delrin,' nayiloni imakhala chizindikiro chake pamapulojekiti opanga makina ndi kusindikiza kwa 3D, chifukwa cha kuthekera kwake kukana kutha.

Komabe, ngwazi iliyonse ili ndi zokonda zake. Kwa Nylon, ndikukonda kwake chinyezi. Imamwa mpaka 1.2% ya kulemera kwake m'madzi ikaviikidwa kwa maola 24, malo apaderawa amatha kupotoza kukula kwake ndi mawonekedwe ake, zomwe zimakhudza kukhazikika kwake m'malo achinyezi. Chifukwa chake, tikamaganizira za 'chomwe chili cholimba, nayiloni kapena teflon,' ndikofunikira kuzindikira kuti m'malo omwe amakhala ndi chinyezi, nayiloni imatha kuwonetsa kusinthika kwachinyengo.

Komabe, musatengeke kwathunthu ndi mikangano ya 'ptfe vs nylon' osavomereza kusinthasintha kodabwitsa kwa Nylon. Kuchokera ku nsalu mpaka kuumba jekeseni, kusinthasintha kwake kumathandizira kudalirika kwake m'mafakitale osiyanasiyana. Poyerekeza, zinthu monga 'delrin heat resistance' kapena 'teflon ptfe' kukhazikika kwamankhwala kungayang'anire kwambiri pazantchito zina, kuwonetsetsa kuti chinthu chilichonse, kuphatikiza nayiloni, chimapeza malo omwe mawonekedwe ake apadera amawala kwambiri.

Kumbukirani, kusankha chinthu, kaya pa mkangano wa 'nayiloni ndi teflon' kapena kupitirira apo, kumayenderana ndi kugwirizanitsa zofuna za polojekiti ndi mphamvu zakuthupi. Nayiloni, yokhala ndi mphamvu zamakina olimba komanso yosamva kuvala, imachita bwino pamapulogalamu ambiri, malinga ngati kuyanjana kwake ndi chinyezi kumawerengedwa. Sinthani zisankho zanu bwino, ndikuwona ntchito zanu zikuyenda bwino!

Delrin (POM): Apex of High Stiffness and Dimensional Stability

Tiyeni tilumikize kufufuza kwathu ndi kulowa mu dziko la Delrin, dzina lachizindikiro lomwe likuluka nkhani yake mu gawo la thermoplastics, ndendende polyoxymethylene (POM).

Delrin imawonetsa zidziwitso zake ndi kuuma kodziwika, kukhazikika kowoneka bwino, komanso kutsika kwachikondi kwa chinyezi. Ganizirani izi ngati zinthu zodalirika, makamaka pamene mukusowa chinachake chokhala ndi msana pazigawo zanu zamakina chifukwa cha kukhazikika kwake kwapamwamba komanso mphamvu zowonongeka zomwe zimavina pakati pa 69-79 MPa. Kusakaniza uku kwa chithumwa chakuthupi kumapangitsa kuti ikhale yokondedwa muzochitika zomwe zimafuna kusakanikirana kulondola komanso kusasunthika.

Kuyerekeza kwa 'delrin vs nayiloni' nthawi zambiri kumachitika, makamaka pozungulira ubale wawo ndi chinyezi. Zilowerereni Delrin kwa maola 24 ndipo imangotenga chinyezi 0.25%, ndikupangitsa kuti ikhale yolimba pamene kuvina kwa zinthuzo ndi chinyezi kumaseweredwa, ndikuphimba Nayiloni m'mapulojekiti omwe chinyezi chimakhala chosewera kwambiri.

Muzochitika zomwe zimafuna chinthu chokhala ndi chikhalidwe chokhazikika, makamaka pamakina opanga makina, Delrin akukwera. Chinyezi chake chochepa komanso kusasinthika mumiyeso yake kumapangitsa kuti chiwonekere, nthawi zambiri chimachiyika pachimake pakangokambirana za 'nayiloni vs delrin'.

Ndizofunikira kudziwa kuti ngakhale ETFE ndi PTFE onse ali m'banja la fluoropolymer, nkhani zawo zopanga zimasiyana. Kudziwa nkhani zawo zopanga kumawunikira momwe amagwirira ntchito komanso njira zogwiritsira ntchito.

Mwachidule, pamene zokambirana za 'delrin vs teflon' kapena 'nayiloni vs teflon' zingakusokonezeni, kumbukirani: zonsezo ndi kugwirizanitsa zinthu zapadera za zinthu, monga mphamvu zamakina a Delrin ndi kukana kuvala, ndi zosowa za polojekiti yanu. Ndilo kiyi yotsegula chitseko cha dziko limene ntchito zanu sizimangopambana; amapambana. Chifukwa chake sankhani mwanzeru, ndipo ntchito zanu ziziyenda bwino mpaka kalekale!

Aokai ndi akatswiri opanga PTFE ❖ kuyanika zipangizo , timapereka zinthu kuphatikizapo PTFE nsalu, PTFE matepi, Malamba a conveyor a PTFE, etc., kupita ku malo athu mankhwala kuphunzira zambiri, kapena lumikizanani ndi gulu lathu , ndife okondwa kukupatsani chithandizo.
