Momwe Mungatsimikizire Kukhazikika kwa PTFE Nsalu Yotentha Kwambiri Panthawi ya Sintering

Sintering ndi gawo lofunikira pomwe tinthu tating'onoting'ono ta PTFE timasungunuka, timatuluka, ndikuphatikizana kukhala filimu yopitilira. Koma ndi siteji kumene flatness kutayika mosavuta. Kukangana kosagwirizana, kutentha kwachangu, kapena kusadziletsa kokwanira kungayambitse makwinya osasinthika, m'mphepete mwa mafunde, ndi ma warpage omwe sangathe kuwongoleredwa pambuyo pake.

Mfundo yofunika kwambiri pakusunga kusalala bwino ndikuwongolera kupsinjika, kutentha, ndi njira zodziletsa - kupangitsa mawonekedwe ogwirizana a gawo lapansi la fiberglass ndi zokutira zosungunuka za PTFE.

Aokai PTFE  (PTFE fiberglass cloth ) yapanga njira zolimba za sintering kuti zitsimikizire kukhazikika kosasinthasintha. Bukuli lili ndi mfundo zisanu zofunika kwambiri zowongolera kukhazikika kosasunthika pakupanga kwakukulu.

Kuletsa Zida - Stenter Machine Ndi Yovomerezeka

Iyi ndiye njira yayikulu yopewera kuchepa kwa weft ndi ma wavy selveges. Pin stenter (kapena clip stenter) iyenera kuyikidwa mkati mwa ng'anjo yotentha.

1. Kujambula mopingasa

Pini mbale kuboola nsalu m'mphepete. Posintha makulidwe a unyolo wa conveyor, kupsinjika kocheperako kumagwiritsidwa ntchito - kapena osachepera, m'lifupi mwansalu yoyambirira imasungidwa kuti ithane ndi kupsinjika kwa kutentha kwa gawo lapansi pakutentha kwakukulu. Popanda choletsa ichi, m'lifupi mwake nsaluyo imachepa ndipo m'mphepete mwake mumakhala wavy.

2. Kuwongolera kwa nthawi yayitali

Kusiyanitsa kwa liwiro lolondola pakati pa zodzigudubuza zakutsogolo ndi zakumbuyo kuphatikiza kuwongolera kotsekeka kotsekeka kumapereka kupsinjika kwautali kwambiri komanso kokhazikika:

• Kuvuta kwambiri - kumang'amba zokutira kapena kumayambitsa kuchepa kwa kuzizira komanso kutha kwa nkhondo

• Kukanika kosakwanira - kumayambitsa makwinya aatali (nsaluyo 'magulu mmwamba')

Mbiri ya Kutentha kwa Sayansi - Kutentha kwa Gradient ndi Kuzizira Kochepa

Kupendekera kopendekera kwa kutentha pang'ono, kusungunuka kwathunthu, ndi kuziziritsa pang'onopang'ono kumafunikira kuti muchepetse kugwedezeka kwamafuta ndi kupsinjika komwe kumayambitsa kupsinjika.

1. Malo otentha

Kutentha kumakwera pang'onopang'ono kuzungulira malo osungunuka a PTFE (327 ° C) kuti azitha kutentha mkati ndi pamwamba pa nsalu. Kutentha kwakukulu kwaderalo kapena kutentha kwachangu kumabweretsa kutsika kosagwirizana ndi ma creases okhazikika. Cholinga chake ndi kulola kuti kutentha kulowerere mofanana kudzera mu makulidwe a nsalu kusanayambe kusungunuka kwathunthu.

2. Sintering holding zone

Kutentha kosalekeza kumasungidwa pa 380-400 ° C kwa nthawi yokwanira yokhalamo. Izi:

• Amasungunula kwathunthu tinthu tating'ono ta PTFE kukhala filimu yopitilira

• Imamasula kupsinjika kotsalira kwamkati kwa fiberglass pansi pamikhalidwe yokhazikika

• Imawonetsetsa kusakanikirana kwathunthu ndi kachulukidwe

3. Malo ozizirira - nthawi zambiri amanyalanyazidwa, koma ovuta

Iyi ndi nthawi yomwe nkhondo zambiri zimachitika. Kuziziritsa pang'onopang'ono kumafunika pamene mukusunga zoletsa mpaka kutentha kumatsika pansi pa PTFE crystallization point (pafupifupi 310 ° C ).

Lamulo lofunikira: Kuziziritsa mwachangu kwa mpweya kumapangitsa kutsika kosagwirizana pakati pa zokutira ndi gawo lapansi - kumabweretsa kupindika kosalekeza kapena kupindika komwe sikungafanane pambuyo pake. Sungani nsaluyo moletsa mpaka PTFE itasungunuka bwino ndikutsekedwa mu mawonekedwe ake omaliza.

Substrate Pretreatment ndi Coating Uniformity

Kutsika pansi pa sintering kumadalira zomwe zimachitika nsalu isanalowe mu ng'anjo.

1. Pre-kuchepa kwa nsalu yoyambira

Pamaso PTFE impregnation, fiberglass nsalu akukumana mkulu-kutentha dewaxing ndi chisanadze kutsika kuchotsa kuluka yotsalira nkhawa. Izi zimachepetsa kwambiri kuchepa kwachiwiri panthawi ya sintering ndikuyika maziko a flatness apamwamba.

Chidziwitso cha Aokai PTFE: Popanda kutsika, galasi la fiberglass lidzayesa kugwirizanitsa panthawi ya sintering - kumenyana ndi kuletsa kwa stenter ndikuyambitsa kugawanika kosagwirizana.

2. Uniform ❖ kuyanika makulidwe

PTFE wosanjikiza wolowetsedwa ayenera kukhala ndi makulidwe osasinthasintha pansalu yonse. Kupaka kosagwirizana kumayambitsa kusungunuka kwa nthawi - madera owonda amasungunuka mwachangu kuposa madera okhuthala - kutulutsa kupsinjika komwe kumafanana ndi mawonekedwe a peel lalanje ndikuwononga kukhazikika.

• Kuwongolera kolondola kwa kulowetsedwa, kuphimba tsamba la dokotala, ndikufinya njira zopukutira ndikofunikira.

• Ngakhale kusiyanasiyana kwakung'ono (0.01mm) kumatha kuyambitsa zolakwika zowonekera.

Kukonzekera kwa Airflow ndi Zowongolera Zolondola

1. Kutentha kwa mpweya wotentha

Adopt pamwamba-ndi-pansi-kuwomba kapena yunifolomu yozungulira mpweya wotentha mkati mwa ng'anjo kuti mupewe mpweya wolimba wa mbali imodzi womwe umagunda mwachindunji nsalu - zomwe zimayambitsa zizindikiro za flutter. Thandizo lokhazikika la mpweya wokhazikika mu uvuni wopingasa limalepheretsa nsalu kuti isagwedezeke pazitali zomwe zayimitsidwa.

2. Kufanana kwakukulu kwa zodzigudubuza

Zodzigudubuza zonse ndi zodzigudubuza ziyenera kukhala zogwirizana kwambiri ndikukhala zaukhondo popanda zotsalira zomata:

• Kupatuka kwa nsalu ting'onoting'ono kumabweretsa kukangana kosagwirizana mbali zonse ndi makwinya akunja

• Makina owongolera m'mphepete mwawokha adzakhala ndi zida

• Kuyeretsa nthawi zonse kumalepheretsa zomatira zomwe zimayambitsa kusintha kwamphamvu

Chidule - The Flatness Formula

Kukhazikika kwangwiro sikutheka ndi mphamvu yakunja kukanikiza. M'malo mwake, pansi pa kuletsa koyenera kwa makina a stenter, kutentha kwa yunifolomu ndi kukanikiza kumasungunuka ndikuphatikiza zokutira za PTFE ndi gawo lapansi la fiberglass kuti likhale losalala, ndi kupsinjika konse kotsalira kumatulutsidwa kudzera mukuzizira pang'onopang'ono.

Kupatuka mu ulalo uliwonse wanjira kumatha kuwoneka ngati pamwamba pansalu.

Aokai PTFE imayang'anira magawo onsewa kuti apereke nsalu za PTFE zotsimikizika. Pazinthu zomwe zimafuna nsalu zopyapyala (mwachitsanzo, PCB laminating, ma solar laminators), timapereka mawonekedwe olimba a flatness ndi njira zina zowonjezera.

Zomwe zili pamwambapa zaukadaulo zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mukufuna kuphunzira mwatsatanetsatane, zochitika zogwiritsira ntchito ndi njira zothetsera makonda amtundu wathu wonse, kuphatikizapo nsalu ya PTFE yotentha kwambiri, tepi yomatira ya PTFE, lamba wotentha kwambiri wa PTFE, lamba wosasunthika, lamba wamtundu umodzi wa PTFE, nsalu yotchinga kutentha kwambiri, kukhudzana ndi magalasi otetezedwa ndi kutentha, chonde lemberani magalasi otetezedwa ndi kutentha.
