Momwe Fiberglass Thermal Shrinkage Imakhudzira PTFE Tape Dimensional Stability

A Tepi ya PTFE yomwe imafota, yopindika, kapena yopindika mukamagwiritsa ntchito ndikulephera kofala. Zomwe zimayambitsa nthawi zambiri zimachokera ku gawo limodzi: kuchuluka kwa kutentha kwa gawo lapansi la fiberglass..

Pa PTFE sintering pa 360-400 ° C ndi zomatira kuchiritsa pa 150-200 ° C, ndi Nsalu ya magalasi a fiberglass imakula ndipo, movutikira kwambiri, imachulukira osasinthika chifukwa cha kupsinjika kotsalira koluka. Ngati kupsyinjika kumeneku sikunathetsedwe musanayambe kuvala, kumakhala cholakwika chobisika - kuchititsa kuti tepiyo ikhale yocheperapo, yopindika, kapena delaminate ikatenthedwa.

Aokai PTFE imagwiritsa ntchito magawo otenthetsera a fiberglass kuti athetse vutoli. Nkhaniyi ikufotokoza chomwe chimayambitsa kuchepa kwa kutentha, zotsatira zake pa gawo lililonse lokonzekera, ndi njira yothetsera: nsalu yokonzedweratu kutentha ndi <0.5% shrinkage pa 400 ° C.

Choyambitsa Mizu - Kupanikizika Kotsalira Kuchokera Kuluka

Kutsika kwamafuta kumachokera ku nkhawa zotsalira zamkati zomwe zimasonkhanitsidwa panthawi yojambula ulusi wagalasi ndi kuluka nsalu. Nsalu ya fiberglass yopanda kutentha kwathunthu imatha kutsika mosasinthika ikatenthedwa pamwamba pa kutulutsa kwake kupsinjika (kuchepa kodabwitsa kumayambira pamwamba pa 300 ° C).

Kupsinjika kulikonse komwe kumatulutsidwa mosakwanira kapena kutsika kosasunthika kumakhala vuto lalikulu lobisika lomwe limayambitsa miyeso yosakhazikika ya tepi. Kupsyinjika kumeneku 'kotsekedwa' mkati mwansalu panthawi yoluka ndipo kumatulutsa kokha ikatenthedwa kufika kutentha kokwanira.

Zokhudza Panthawi ya PTFE Sintering - The Critical Stage

PTFE sintering kutentha kufika 360-400 ° C, kutali kwambiri isanayambike kutentha kwa fiberglass shrinkage matenthedwe matenthedwe, kupanga siteji imeneyi chinthu chofunika kwambiri dimensional ntchito.

1. Kutsekeka kotsekeka kumapangitsa kuti pakhale zovuta zobisika

Ngati atakonzedwa pansi pa kupsinjika pang'ono, nsalu ya fiberglass imachepa momasuka komanso mozama, zomwe zimapangitsa kutalika kwake komanso kukula kwake. Ngati kupanikizika kwambiri kumagwiritsidwa ntchito kuti muchepetse kuchepa, ulusi wagalasi umakulitsidwa mwamphamvu. Pafupifupi 380 ° C, PTFE yosungunuka imalowa ndikukulunga ulusi wotambasula; kuziziritsa ndi kupanga, chizolowezi chobisika cha shrinkage chimatsekeredwa mpaka kalekale mkati mwa gawo lapansi ngati kupsinjika kwakukulu kotsalira. Tepiyo ikatenthedwanso m'machitidwe amtsogolo, kupsinjika kotsaliraku kumayambitsa kuchepa kwa gawo lapansi ndikuwononga mwachindunji kukhazikika kwa mawonekedwe.

2. Kusagwirizana kwa gawo lapansi kumachepetsa ❖ kuyanika kufanana

Kuchepa kofanana kwa kutentha kumachulukira m'magawo osiyanasiyana a nsalu (monga m'mphepete motsutsana ndi malo apakati) panthawi ya sintering triggers deformations kuphatikiza m'mphepete mwa mafunde, m'mphepete mwake, ndi zotupa pamwamba . Kutsika kwa gawo lapansi kosagwirizana kumabweretsa makulidwe a zomatira zosagwirizana m'njira zotsatizana, kupangitsa thovu la mpweya mosavuta kapena kusamata bwino pa nthawi ya kuyanika, ndikuwonongeka kwapakatikati komanso kukhazikika kwamatepi omalizidwa.

Zomwe Zimakhudza Pamachiritso Omatira - Kuchepetsa Kupsinjika Kwambiri

Machitidwe omatira (zomatira za silicone-sensitive-sensitive, zomatira za acrylic, etc.) zimachiritsa pa 150-200 ° C. Kutenthaku ndikocheperako poyerekeza ndi kuchuluka kwa sintering koma kokwanira kuyambitsa kupsinjika kotsalira kotsekeka mkati mwa gawo lapansi, zomwe zimabweretsa zovuta zingapo.

1. Kutsika kwachiwiri kumayambitsa zolakwika zapamtunda ndi kupotoza kwa dimensional

Mukalowa mu uvuni wochiritsira, kupsinjika kotsalira mkati mwa gawo lapansi kumatulutsa ndikupangitsa kuchepa kwa tepi. Izi zimabweretsa:

• Kuchepetsa m'lifupi kwambiri

• Ming'alu yaying'ono, mawonekedwe a peel lalanje, kapena kulephera kophatikizana pa zomatira (monga shrinkage imachitika nthawi imodzi ndikuchiritsa)

• Kusinthasintha kwautali mu makulidwe a zomatira ndi makwinya a zomangira zotulutsa (chifukwa cha kusagwirizana pakati pa liwiro la shrinkage ya nsalu ndi liwiro lopaka mphira)

2. Kupiringa kwamatenthedwe kumathetsa kulondola kwa kukonza

Gawo laling'ono limalumikizana mwachangu ndi kupsinjika kotsalira kotentha, pomwe zomatira zochiritsidwa bwino zimakhala ndi gawo losiyana la kukulitsa kwamafuta, zomwe zimapangitsa kusagwirizana kwakukulu pakati pa zigawo ziwiri. Tepiyo imapindika nthawi yomweyo ikatulutsidwa kuchokera kuzitsulo zotulutsa kapena kutenthedwa pakagwiritsidwa ntchito - kulephera kukhazikika ndikutaya kuwongolera ndi magwiridwe antchito.

Kutulutsa Kupsinjika Kwambiri Pamapeto Ogwiritsa Ntchito - Kusakhazikika Kwanthawi Yaitali

Kupsyinjika kotsalira komwe sikumathetsedwa kwathunthu pakuchiritsa zomatira kumapitilirabe mpaka kumaliza ntchito. Pansi pa masking otentha kwambiri, kutentha kwa kutentha, kapena kutentha kwa njinga zamoto (mwachitsanzo, 260 ° C zokutira ufa), tepiyo imachepa pang'onopang'ono ndi mosalekeza.

Zotsatira:

• Malire a masking osinthidwa (mizere yosindikizira imasuntha)

• Kukweza m'mphepete kapena kulephera kumamatira

• Kutayika kwathunthu kwa kukhazikika kwazithunzi

Ichi ndichifukwa chake matepi ena amalephera m'munda ngakhale atadutsa kuyendera koyambirira - kupanikizika kobisika kumatulutsidwa pang'onopang'ono pakapita nthawi komanso kutentha.

Core Solution - Chotsani Shrinkage Musanayambe Sintering

Kupanga matepi omatira a PTFE okhazikika, kukakamira kukakamira panthawi yokonza sikungathetse vuto la kuchepa kwambiri. Kuchotsa kwathunthu kwa fiberglass shrinkage iyenera kukwaniritsidwa pa gwero.

1. Njira ya Aokai PTFE

1. Gwiritsani ntchito nsalu yoyambira yotentha (yosakhazikika) ya fiberglass - kuchuluka kwa kutentha kumayendetsedwa mosamalitsa pansi pa 0.5% pansi pamiyeso ya 400 ° C × 10 mphindi (miyezo yolimba yomwe ikupezeka pamakalasi apamwamba).

2. Onjezani njira yowotchera yotentha kwambiri musanalowetse PTFE kapena kupaka - kulola kuti nsalu ya fiberglass imalize kutsika kwaulere ndikumasula kwathunthu kupsinjika kwamkati musanalowe m'dera la sintering.

2. Zotsatira zake

Kuchepa kwa kutentha kwa nsalu ya fiberglass kukachepa, kusiyanasiyana kwapang'onopang'ono pakumangirira ndi zomatira kumangochokera kukukula kwamafuta ndi kutsika kwa utomoni ndi zomatira - ndi kukula kochepa kwambiri kuposa kutsika kotsalira koyendetsedwa ndi kupsinjika. Izi zimatsimikizira:

• Kukhazikika kwa Dimensional (kutalika ndi m'lifupi)

• Kusalala kwa pamwamba

• Kukana kutentha ndi kudalirika kwa nthawi yaitali

Aokai PTFE imasankha magawo a fiberglass okhala ndi kutentha kwathunthu okhala ndi mitengo yolembedwa yocheperako. Titha kupereka mayeso malinga ndi zomwe kasitomala amafuna.

Chidule - Mfundo Yoyamba Kuchepa

Aokai PTFE imalimbikitsa magalasi a fiber oikidwa kale ndi kutentha ndi kuchepera <0.5% pazantchito zonse zofunika kwambiri. Kwa makasitomala omwe amafunikira miyeso yokhazikika kwambiri, timapereka magiredi apamwamba kwambiri okhala ndi shrinkage <0.3% pa ​​400°C.

Izi zaukadaulo zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Material Technology Co., Ltd.

Ngati mukufuna mwatsatanetsatane, mawonekedwe ogwiritsira ntchito ndi njira zothetsera makonda athu opangira zinthu zonse kuphatikiza nsalu za PTFE zotentha kwambiri, matepi amamatira otentha kwambiri a PTFE, malamba a PTFE ma mesh conveyor, malamba osakanikirana opanda makina, nsalu yotchinga mbali imodzi ya PTFE, magalasi osasunthika, kulumikizana ndi magalasi apamwamba, chonde tumizani magalasi osagwira kutentha ndi ma fiber. njira pansipa:
