Zofunika Pakuzizira Mlingo Pa Sintering wa PTFE High-Kutentha Nsalu

I. Zofunikira Zoyambira pa Kuzizira kwa Mtengo

Mofulumira kudutsa crystallization-sensitive zone Malo osungunuka a PTFE ndi 327 ° C, ndipo kutentha kwa sintering kumachokera ku 380 ° C mpaka 400 ° C. Pakuchepetsa kutentha, chofunikira kwambiri ndikuwoloka mwachangu malo otentha mozungulira 310 ~ 315 ° C pomwe kuchuluka kwa crystallization kumakwera kwambiri.

Njira zogwiritsidwira ntchito zomwe mwalangizidwa Mukangotuluka mung'anjo ya sintering, gwiritsani ntchito kuziziritsa mpweya mokakamiza, kuziziritsa kuphulika kwa mpweya, kapena gwiritsani ntchito makina oziziritsira / madzi ozizira kuti muchepetse kutentha kwa nsalu pansi pa 250 ° C.

 

Zizindikiro zoziziritsa zolozera Kutengera makulidwe azinthu, kuzizirira kwanthawi zonse kuyenera kukhala kosachepera 30~50°C/mphindi. Pa nsalu yopyapyala yotentha kwambiri (0.08mm ~ 0.25mm), kuziziritsa kwa mpweya kumatha kuzirala kuposa 100 ~ 200 ° C/mphindi, kupangitsa kuti ndidutse nthawi yomweyo kudera lofunika kwambiri la crystallization.

 

II. Njira Yoyendetsera Ntchito: Momwe Kuzirala Kumakhudzira Kagwiritsidwe Ntchito Kazinthu

Crystallinity imatsimikizira zomwe zili pachiwopsezo Mitundu yoziziritsa imayang'anira crystallinity ya PTFE, yomwe imawonjezeranso mikhalidwe yofunika kwambiri yokutira kuphatikiza kusinthasintha, kumamatira komanso kusagwira ndodo.

 

Kufananiza kwa Magwiridwe Pakati pa Kuzizira Kwambiri ndi Pang'onopang'ono

Kufotokozera kwa Microstructural Kuzizira kofulumira kumalepheretsa kukula kwa ma spherulites akuluakulu ndikupanga mawonekedwe abwino a microcrystalline. Izi zimapangitsa kuti filimu ya PTFE ikhale yowonjezereka komanso yowonjezereka, pamene kuchepetsa kupanikizika kotsalira pakati pa zokutira ndi fiberglass gawo lapansi.

 

III. Mfundo zazikuluzikulu zowongolera mu Mass Production

 

Chitsimikizo kuzirala yunifolomu Kuziziritsa kutuluka kwa mpweya kapena zodzizirira zoziziritsa kuyenera kukhalabe kutentha kosasinthasintha m'lifupi mwa nsalu. Kusafanana kwa kristalo kumapangitsa kuti pakhale mawanga kapena makwinya.

 

Pewani kutenthedwa kwambiri kwa nsalu Pansalu yokhuthala kwambiri yotentha kwambiri (0.5mm ndi kupitilira apo), kupopera mbewu mankhwalawa madzi mwachindunji kapena kukhudzana pompopompo ndi zodzigudubuza zozizira kwambiri kungayambitse kupunduka kwakukulu komwe kumadza chifukwa cha kuchepa kwa kutentha kosagwirizana pakati pa gawo lapansi ndi zokutira. Kayendedwe kabwino ka ntchito ndi kamphepo kamene kamakhala kozizirira mpaka pansi pa 250°C musanazizirenso.

 

Kasamalidwe koziziritsa kwa ma multi-pass sintering Panjira za kulowetsedwa kwa ma multi-impregnation & multi-sintering, kuziziritsa kwapang'onopang'ono ndikovomerezeka pamayendedwe apakatikati a sintering. Komabe, gawo lomaliza la sintering liyenera kuziziritsa mwachangu kuti muteteze magwiridwe antchito abwino kwambiri.

IV. Chidule Chachidule

1. Kuziziritsa mwachangu ndikofunikira positi PTFE nsalu sintering kuti PTFE yosungunula kudumpha mkulu-kutentha crystallization zone mwamsanga.

2. Kuzizira kofulumira kumapanga mawonekedwe otsika a crystallinity microcrystalline, omwe ndiye chinsinsi cha kusinthasintha kwapadera, kukana kupindika komanso kusagwira ndodo kwanthawi yayitali.

3. Yang'anirani bwino kuzizira kofanana, kupewa kugwedezeka kwa kutentha, ndikukhazikitsa nthawi yoziziritsa ya sintering yamitundu ingapo kuti mukhazikitse mtundu wokhazikika wazinthu.

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

Ngati mukufuna kudziwa mwatsatanetsatane, zochitika ntchito ndi mayankho makonda athu zonse katundu katundu kuphatikizapo PTFE mkulu kutentha nsalu, PTFE mkulu-kutentha zomatira tepi, PTFE mkulu-kutentha mauna lamba, msokonezo kutentha atolankhani lamba, single-mbali PTFE nsalu, mkulu kutentha zosagwira magalasi, kukhudzana ndi magalasi zosagwira magalasi, chonde kukhudzana ndi magalasi zosagwira magalasi conveyor.

Nthawi zonse timatsatira filosofi yautumiki waukatswiri ndi kukhulupirika, kupereka ndi mtima wonse mayankho amakampani omwe amasiyanitsidwa ndi ntchito zamakasitomala oganiza bwino kwa onse othandizana nawo!
