I-Fiberglass Thermal Shrinkage Ithinta kanjani i-PTFE Tape Dimensional Stability

A Itheyiphu ye-PTFE eshwabana, egoqa, noma i-warps ngesikhathi sokusetshenziswa ukwehluleka kwenkambu okuvamile. Imbangela ngokuvamile ilandela emuva kupharamitha eyodwa: izinga lokuncipha okushisayo kwe-fiberglass substrate..

Ngesikhathi se-PTFE sintering ku-360-400 ° C kanye nokuphulukisa okunamathelayo ku-150-200 ° C, Indwangu ye-fiberglass ithola ukunwetshwa okushisayo futhi, ngokubaluleke kakhulu, ukushwabana okungenakulungiseka okusuka ekucindezelweni kokwaluka okusalayo. Uma lokhu kucindezeleka kungaqediwe ngaphambi kokumboza, kuba yisici esifihliwe - okwenza i-tape inciphise, igobe, noma i-delaminate lapho ishisa.

I-Aokai PTFE isebenzisa ama-substrates e-fiberglass asethwe ngokugcwele ukuze iqede le nkinga. Lesi sihloko sichaza umsuka wokuncipha kokushisa, imithelela yawo esigabeni ngasinye sokucubungula, kanye nesixazululo esiyinhloko: Indwangu esethwe ngaphambilini ukushisa eno-<0.5% ishwabana ku-400°C.

Imbangela - Ukucindezeleka Okusalelayo Okuvela Ekwalukeni

Ukuncipha kokushisa okushisayo ngokuyisisekelo kuvela ekucindezelekeni kwensalela yangaphakathi enqwabelene ngesikhathi somdwebo we-fiber yengilazi kanye nokulukwa kwendwangu. Indwangu ye-fiberglass ngaphandle kokusetha ukushisa okugcwele izoncipha ngendlela engenakulungiseka uma isishisiswe ngaphezu komkhawulo wayo wokukhipha ingcindezi (ukuncipha okuphawulekayo kuqala ngaphezu kuka-300°C).

Noma iyiphi ingcindezi yokuncipha ekhululwe ngokungaphelele noma engaphoqelekile iba inkinga ecashile edala izilinganiso zamatheyiphu ezingazinzile. Lokhu kucindezeleka 'kukhiyiwe' esakhiweni sendwangu ngesikhathi sokweluka futhi kukhishwa kuphela uma kushisiswe ezingeni lokushisa elanele.

Umthelela Ngesikhathi Se-PTFE Sintering - Isiteji Esibalulekile

Izinga lokushisa le-PTFE sintering lifinyelela ku-360-400°C, lidlula kude izinga lokushisa lokuqala le-fiberglass shrinkage ezishisayo, okwenza lesi sigaba sibe yisici esinqumayo sokusebenza kobukhulu.

1. Ukucindezeleka kokuncipha okukhiyiwe kudala amaphutha acashile

Uma icutshungulwa ngaphansi kwe-tension ephansi, indwangu ye-fiberglass incipha ngokukhululekile futhi kakhulu, okuholela kubude obungalingani nobukhulu nobubanzi. Uma ukungezwani okudlulele kusetshenziswa ukuze kunqandwe ukuncipha, imicu yengilazi yelulwe ngenkani. Cishe ku-380°C, i-PTFE encibilikisiwe ingena bese isonga imicu elulekile; ngemva kokupholisa nokubunjwa, ukuthambekela kokuncipha okucashile kukhiywa unomphela ngaphakathi kwe-substrate njengokucindezeleka okukhulu kwensalela yokuqina. Uma itheyiphu isishisiswe kabusha ezinqubweni zakamuva, lokhu kucindezeleka okusalayo kubangela ukuncipha kwe-substrate futhi kubhidlize ngokuqondile ukuqina kwe-dimensional.

2. Ukungalingani kwe-substrate flatness kubukela phansi ukufana kwe-coating

Amazinga okuncipha okushisayo angahambisani kuzo zonke izindawo zendwangu ehlukene (isb., umphetho uma uqhathaniswa nendawo emaphakathi) phakathi nokuguqulwa kwe-sintering trigger okuhlanganisa imiphetho yamagagasi, amamajini ayinkomishi, namaqhuqhuva angaphezulu . Indawo engalingani ye-substrate iholela ekujikeni kokunamathelayo okungalingani ezinqubweni ezilandelayo, kubangele kalula amabhamuza omoya noma ukunamathela okungekuhle ngesikhathi sokucwala, kanye nokuwohloka ngokungaqondile kokubili kokuqina nokusebenza kwamateyipu aqediwe.

Umthelela Ngesikhathi Sokwelapha Okunamathelayo - Ukunciphisa Ukucindezeleka Kwesibili

Amasistimu okunamathela (okunamathelayo okuzwela ukucindezela kwe-silicone, okunamathelayo kwe-acrylic, njll.) aphulukisa ku-150-200°C. Leli zinga lokushisa liphansi kunebanga le-sintering nokho lanele ukwenza kusebenze ingcindezi esele ekhiyiwe ngaphakathi kwe-substrate, okuletha imiphumela emibi eminingi.

1. Ukuncipha kwesibili kubangela ukonakala kwendawo kanye nokuchezuka kobukhulu

Lapho kungena kuhhavini wokwelapha, ingcindezi yokuncipha kwensalela ngaphakathi kwe-substrate ikhipha futhi ibangele ukuncipha kwetheyiphu elinganisekayo. Lokhu kuholela kokuthi:

• Ukwehliswa kobubanzi obudlulele

• Imifantu emincane, ukuthungwa kwekhasi lewolintshi, noma ukwehluleka ukuhlangana endaweni enamathelayo (njengoba ukushwabana kwenzeka kanyekanye nokuphulukiswa)

• Ukushintshashintsha kwe-longitudinal kugqinsi lokunamathelayo kanye nokushwabana kwama-liner akhululayo (ngenxa yokungafani phakathi kwesivinini sokuncipha kwendwangu kanye nesivinini somugqa wamarola wokunamathela)

2. Ukugoqa okushisayo kuqeda ukunemba kokucubungula

Isendlalelo se-substrate sisebenza ngokusebenza ngaphansi kwengcindezi eshisiwe yensalela, kuyilapho ungqimba olunamathelayo olulapheke ngokugcwele lune-coefficient ehlukile yokunwetshwa okushisayo, okudala ukungafani kokucindezeleka okukhulu phakathi kwezingqimba ezimbili. Itheyiphu iyagoqa ngokushesha lapho ihlutshiwe kuma-liner okukhishwayo noma ichayeke ekushiseni ngesikhathi sokusetshenziswa - yehluleka ukubeka isicaba futhi ilahlekelwa ukulawuleka kobukhulu nokusebenza.

Ukukhishwa Kwengcindezi Eqhubekayo Ngesikhathi Sokusebenzisa - Ukungaqini Kwesikhathi Eside

Ingcindezi yokuncipha kwensalela engaqediwe ngokuphelele ngesikhathi sokunamathisela okunamathelayo iyaqhubeka nokusetshenziswa komkhiqizo oqediwe. Ngaphansi kokufihla izinga lokushisa eliphezulu, i-thermal lamination, noma izimo zebhayisikili ezishisayo (isb, i-powder coating engu-260°C), itheyiphu incipha kancane kancane futhi ngokuqhubekayo.

Imiphumela:

• Imingcele yokufihla eguquliwe (imigqa yokuvala iyahamba)

• Ukuphakamisa umphetho noma ukwehluleka ukunamathela

• Ukulahlekelwa okuphelele kokuzinza kwe-dimensional

Yingakho amanye amateyipu ehluleka ensimini ngisho nangemva kokudlula ukuhlolwa kokuqala - ukucindezeleka okucashile kukhishwa kancane kancane ngokuhamba kwesikhathi kanye nokuchayeka kokushisa.

Isixazululo Esiyinhloko - Khipha Ukuncipha Ngaphambi Kokwenza I-Sintering

Ukwenza amateyipu okunamathisela e-PTFE azinze ngohlangothi, ukungezwani okuphoqelekile okwelula ngesikhathi sokucubungula akukwazi ukuxazulula izinkinga zokuncipha ngokuyisisekelo. Ukususwa okuphelele kwe-fiberglass shrinkage kufanele kufinyelelwe emthonjeni.

1. Indlela ye-Aokai PTFE

1. Sebenzisa indwangu yesisekelo ye-fiberglass esethwe ngokugcwele (eyashwabana ngaphambi kokushwabana) - izinga lokushwabana elishisayo elilawulwa ngokuqinile ngaphansi kuka -0.5% ngaphansi kwezimo zokuhlola ezingu-400°C × 10 amaminithi (izindinganiso eziqinile zitholakala kumamaki e-premium).

2. Engeza inqubo yokushisa yangaphambili yokushisa ephezulu ngaphambi kokukhulelwa kwe-PTFE noma ukunamathela - okuvumela indwangu ye-fiberglass ukuthi iqedele ukuncipha kwamahhala futhi ikhulule ngokugcwele konke ukucindezeleka kwangaphakathi ngaphambi kokungena endaweni ye-sintering.

2. Umphumela

Uma izinga lokushwabana okushisayo kwendwangu ye-fiberglass seluncishisiwe, ukuhluka kobukhulu ngesikhathi sokugoba okulandelayo kanye nokunamathiswa kuzovela kuphela ekwandeni okushisayo kanye nokufinyela kweresin nezingqimba ezinamathelayo - ngobukhulu obuncane kakhulu kunokuncipha kwensalela okuqhutshwa yingcindezi. Lokhu kuqinisekisa ngokuyisisekelo:

• Ukuzinza kwe-Dimensional (ubude nobubanzi)

• Ubucaba bobuso

• Ukumelana nokushisa nokuthembeka kwesikhathi eside

I-Aokai PTFE ikhetha kuphela ama-substrates e-fiberglass asethwe ngokugcwele ngokushisa anezilinganiso zokushwabana ezibhaliwe. Singahlinzeka ngedatha yokuhlola ngokwezidingo zekhasimende ngalinye.

Isifinyezo - Isimiso Sangaphambi Kokuncipha

I-Aokai PTFE incoma i-fiberglass esethwe ngaphambili ngokushisa enokuncipha okungu-<0.5% kuzo zonke izinhlelo zokusebenza ezibaluleke kakhulu. Kumakhasimende adinga ubukhulu obuzinze kakhulu, sinikeza amamaki e-premium anokuncipha okungu-<0.3% ku-400°C.
