Kodi mawonekedwe a microstructural a nsalu ya Teflon yotentha kwambiri ndi yotani?

I. Chigoba Cham'munsi: Maonekedwe Opaka Ulusi Wagalasi

1. Mapangidwe a Warp-Weft Interwoven

The Nsalu imalukidwa kuchokera ku ulusi wa magalasi amitundu yambiri mu plain, twill, kapena zoluka zina kuti zipange ma mesh skeleton, okhala ndi ma diameter a monofilament kuyambira ma microns angapo mpaka ma microns khumi, ndi malo osalala.

2. High Porosity

Pamaso pa zokutira, pali ma pores ambiri ang'onoang'ono mkati mwa mitolo ya ulusi komanso pamphambano za warp-weft, zomwe zimapatsa mpata kulowetsedwa kwa PTFE.

II. Coating Morphology: Mapangidwe a 'Island-Coating' a PTFE

1. Full Impregnation Encapsulation

PTFE utomoni likulowerera mu mipata pakati pa aliyense ulusi, kupanga ' analimbitsa konkire ' -mtundu gulu, kumene ulusi galasi kutumikira monga kulimbikitsa gawo ndi PTFE akutumikira monga masanjidwewo mosalekeza. M'magawo ophatikizika, ulusiwo ukhoza kuwonedwa mofananamo mkati mwa utomoni.

2. Surface Nodular Microstructure

The koyera PTFE padziko zimasonyeza osiyana maukonde kapangidwe kake ka tinatake tozungulira (tinthu ting'onoting'ono) cholumikizidwa ndi fibrils zabwino, opangidwa ndi aggregation a apangidwe-unyolo lamellae pa ndondomeko sintering, amene amapereka sanali ndodo ndi kudziona mafuta katundu kwa zakuthupi.

3. Wosanjikiza Wosanjikiza Khungu

Chosanjikiza chapamwamba chimakhala ndi PTFE yoyera, imapanga filimu yapakhungu yowundana, yopanda magalasi yopanda magalasi angapo mpaka makumi a ma microns wandiweyani, yomwe imakhala ngati chotchinga chachikulu cha kusagwira ntchito kwamankhwala, zinthu zopanda ndodo, komanso kutchinjiriza kwamagetsi.

III. Zowonongeka Zazikulu: Microporosity ndi Interface Characters

1. Ma Micropores Otsalira

Kulowetsedwa kosakwanira kapena kucheperachepera panthawi ya sintering kumatha kusiya ma micron-scale voids kapena ming'alu pakati pa mitolo ya ulusi ndi ma interweaving node, zomwe zimapangitsa kuchepa kwa magwiridwe antchito komanso kukana kwa mankhwala.

2. Kulumikizana kwa Chiyankhulo

Ulusi wagalasi ndi PTFE sizigwirizana; microscope, maenje osalala osiyidwa ndi ulusi wokoka amatha kuwonedwa. Kupyolera mu chithandizo chogwirizanitsa wothandizira kapena kulumikiza makina, PTFE imangirira mwamphamvu ulusi, kupititsa patsogolo mphamvu ya mgwirizano.

IV. Makhalidwe a State Condensed: Semi-Crystalline Structure

1. Spherulites ndi Banded Crystals

PTFE ndi semi-crystalline polima. Pambuyo pa sintering wamba, imawonetsa kukhalapo kwa ma spherulites ndi ma kristalo omangika, okhala ndi crystallinity nthawi zambiri kuyambira 50% mpaka 70%, komanso dongosolo lokonzedwa bwino la ma cell.

2. Zotsatira za Crystallinity

Kuwala kwambiri kumapangitsa kuti zinthuzo zikhale ndi kutentha kwanthawi yayitali mpaka 260 ° C komanso kutsika kotsika kwambiri. Kudumphira mopitirira muyeso kapena kutsika pang'onopang'ono kungayambitse kristalo wachilendo, kufupikitsa moyo wautumiki.

Zomwe zili pamwambazi zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Material Technology Co., Ltd.

Ngati mukufuna kudziwa zambiri zatsatanetsatane, mawonekedwe ogwiritsira ntchito, ndi njira zosinthira makonda pazogulitsa zathu zonse, kuphatikiza nsalu ya Teflon yotentha kwambiri, tepi ya Teflon yotentha kwambiri, malamba amtundu wa Teflon, malamba opanda msoko amakina omangira makina, nsalu yotchinga imodzi ya PTFE, yosamva kutentha kwambiri, yosasunthika. fiberglass nsalu, chonde omasuka kulankhula nafe kudzera zotsatirazi:

Nambala Yothandizira:

Bambo Guo +86 18944819998  

Bambo Liu +86 13705266308

Nthawi zonse timatsatira nzeru zaukadaulo komanso zodalirika zautumiki, ndipo tadzipereka ndi mtima wonse kukupatsirani mayankho okhazikika komanso ntchito yachidwi!
