I-PTFE High-Temperature Fabric: Kungani Igoqa Kakuhle nokuthi Yini Ongayenza

Uma uke wasonga ucezu lwe Indwangu ye-fiberglass eboshwe nge-PTFE ngokucijile, mhlawumbe ubone umugqa omhlophe we-crease uvela khona manjalo. Lisonge futhi endaweni efanayo, futhi indwangu ingase idabuke.

Lokhu akulona iphutha - ukuziphatha okungokwemvelo kwezinto ezibonakalayo. Indwangu ye-PTFE enezinga eliphezulu lokushisa iphumelela kakhulu ekumelaneni nokushisa, amakhemikhali, nokunamathela, kodwa ukumelana nokuguquguquka (ukubekezela okugoqiwe okuphindaphindiwe) kuyimpahla yayo eyimishini ebuthakathaka.

I-Aokai PTFE ihlole impilo eguquguqukayo kuwo wonke ugqinsi nama-weave amaningi. Lesi sihloko sichaza ukuthi kungani indwangu igoqa kabi, iyiqhathanise nezinye izinto, futhi inikeze izindlela ezisebenzayo zokubhekana nomkhawulo.

Kungani i-PTFE Fabric Ine-Flex Ukumelana Okubi?

Imbangela ye- fiberglass substrate , hhayi ukunamathela kwe-PTFE.

1. I-Fiberglass - iqinile kodwa i-brittle

Amafayibha engilazi anamandla aqine kakhulu kodwa amade aphansi kakhulu ngesikhathi sekhefu (imvamisa engu-2-4%). Uma igobile ngokuphindaphindiwe, imicu ngayinye ibhekana nokukhathala nokuphuka. Uma ama-fiber ambalwa ephuka, ukucindezeleka kugxile kokusele, okuholela ekusakazweni okusheshayo - indwangu ikhala kalula.

2. I-PTFE enamathelayo – isigcinalwazi esilinganiselwe

Isendlalelo se-PTFE sigcoba imicu yefayibha, sinciphise ukungqubuzana kwangaphakathi futhi sithuthukise ukusebenziseka kalula. Nokho, ayikwazi ukuqeda ukonakala kwengilazi. Ibambezela kuphela ukuphuka kwe-fiber ngamajini amancane.

Iqhathaniswa Kanjani Nezinye Izinto?

Okuthathwayo okungukhiye: I-fiberglass ehlanganiswe ne-PTFE ihlala ekugcineni phakathi nokuya phansi phakathi kwezindwangu ezinezinga lokushisa eliphezulu lokumelana nokuguquguquka. Kungcono kunengilazi engenalutho kodwa kubi kakhulu kunefilimu ye-PTFE emsulwa.

Izici Eziyinhloko Ezithinta Ukumelana Ne-Flex

1. Ukuqina - isici esibaluleke kakhulu

Umthetho wesithupha: Izindwangu ezizacile ziyagobeka kangcono. Ngezinhlelo zokusebenza ezidinga ukugoba okuphindaphindiwe, cacisa ibanga elincane elihlangabezana nezinye izidingo zakho (amandla, izinga lokushisa).

2. Ukwakhiwa kwe-weave

• I-Satin weave - ukuntanta okude kuvumela izintambo ukuthi zishelele kancane, zisakaze ingcindezi egobayo. Impilo engcono yokuguquguquka kune-plain weave.

• I-Plain weave - amaphuzu axhumene aqinile akhiya izintambo; ukucindezeleka kugxile ezimpambanweni zomgwaqo. Ukumelana nokuguquguquka okubi kakhulu.

3. Izinga lokushisa lokusebenza

Emazingeni okushisa aphakeme (200-260°C), ukunamathela kwe-PTFE kuyathambisa, futhi amandla emishini ye-fiberglass ayehla. Lokhu kwenza kube nzima ukumelana nokukhathala. Uma isicelo sakho sibandakanya kokubili ukushisa okuphezulu nokugoba njalo, lindela ukuphila okufushane.

4. I-radius egobayo

Irediyasi enkulu = impilo ende. Ukwakheka okucijile (irediyasi engu-<1mm) kudala ukugoqa okufile ngokuphuka ngokushesha kwefayibha. Kumarola angumhlahlandlela, sebenzisa ububanzi obusebenzayo obukhulu kakhulu. Njengomhlahlandlela onzima, ubukhulu be-roller obuncane obunconywayo bungu-10-20x ubukhulu bendwangu.

Idatha yokuhlola yangaphakathi (Aokai PTFE) : Ngendwangu yokuluka ye-satin engu-0.13mm, ukugoba phezu kwe-mandrel engu-10mm kuzuze imijikelezo engu-500-800 ngaphambi kokuqhekeka okubonakalayo. Ngaphezulu kwe-5mm mandrel, imijikelezo yehla yaya ku-100-150. Over a 2mm mandrel (crease ebukhali), ukwehluleka kwenzeka phakathi 20 imijikelezo.

Izincomo Zokusebenza Ezisebenzayo

Uma okokusebenza kwakho kudinga ukugoba okuphindaphindekayo - okufana nalokhu:

• Amabhande edrayivu we-welder high-frequency

• Amabhande abophezelayo azungeze ama-pulleys amancane

• Ukubhidliza amabhande okuthutha anamajika abukhali

Unezinketho ezintathu:

1. Inketho 1 - Lungiselela ukukhetha kwendwangu ye-PTFE ngaphakathi kwemikhawulo yayo

• Khetha amamaki amancanyana (0.08mm ukuya ku-0.13mm) kunalawo asindayo

• Uncamela ukwaluka kwe-satin kunokulukwa okungenalutho

• Cela idatha yokuhlola ye-MIT kumphakeli wakho (i-ASTM D2176 noma efanayo)

• Idizayini yerediya yokugoba emikhulu esakhiweni somshini

• Yamukela indwangu ye-PTFE njengento esebenzisekayo - hlela ukushintshwa ngezikhathi ezithile (njalo ezinyangeni ezimbalwa kuye ngokubala komjikelezo)

2. Inketho 2 - Shintshela kwifilimu ye-PTFE eqinile

Ifilimu ye-PTFE ehlanzekile (skived) inokumelana nokuguquguquka okukhethekile. Kodwa-ke, ayinakho ukuqiniswa kwe-fiberglass, ngakho-ke inamandla aphansi okuqina futhi ikhala kalula ngaphansi kwengcindezi. Ilungele ukugoba okukhanyayo, okunomfutho ophansi.

3. Indlela yesi-3 - Sebenzisa i-aramid noma enye indwangu ye-organic fiber

I-Aramid (isb, i-Nomex) noma indwangu ye-PPS ehlanganiswe ne-PTFE inikeza impilo engcono eguquguqukayo kunendwangu ye-PTFE esengilazini. I-trade-off: ukumelana nokushisa okuphansi okuqhubekayo (imvamisa engu-≤200 ° C) kanye nezakhiwo ezihlukile zendawo. Ngezinhlelo zokusebenza ezingaphansi kuka-200°C ezinokugoba okukhulu, cabanga ngalezi zindlela ezihlukile.

I-Aokai PTFE ikhiqiza indwangu ye-aramid ehlanganiswe ne-PTFE uma icelwa. Xhumana nathi mayelana nezinga lokushisa nedatha eguquguqukayo.

Isifinyezo - Yazi Imikhawulo, Yakha Ngokufanele

Indwangu ye-PTFE enezinga eliphezulu lokushisa ime kahle ngokumelene nokushuba, ukushisa okuphezulu (260°C), nokuhlasela kwamakhemikhali. Kodwa ukumelana kwayo nokuguquguquka okungekuhle kuyisithiyo sangempela. Ayikwazi ukumelana nokugoqeka okucijile njengamabhande enjoloba noma ifilimu ye-PTFE emsulwa.

Yisebenzise lapho ukugoba kuthambile noma kungavamile.
Lapho ukugoba okucijile noma okuvamile kungenakugwenywa, ncipha, sebenzisa i-satin weave, khulisa i-radius egobayo, noma shintsha okubalulekile.

I-Aokai PTFE inikeza idatha yokuhlola eguquguqukayo yawo wonke amabanga ethu endwangu. Singakusiza ukuthi ukhethe ukujiya okulungile nokuluka ngezidingo zokugoba zohlelo lwakho lokusebenza.

Okuqukethwe kobuchwepheshe kuhlinzekwe ngu I-Jiangsu Aokai New Materials Technology Co., Ltd.

Ukuze uthole imininingwane eningiliziwe nezixazululo ezenziwe ngokwezifiso zendwangu ye-PTFE enezinga lokushisa eliphezulu, itheyiphu, ibhande lemeshi, ibhande lokuhlanganisa, nokuningi:
