Jiangsu Aokai New Materials, inyanzvi inogadzira PTFE yakakwirira-yetembiricha machira, anogovera nhungamiro yehunyanzvi. Wrinkles inogadzirwa paPTFE high-temperature jira (fiberglass jira rakaputirwa nePTFE) panguva yekupisa kunonyanya kukonzerwa nekusaenzana kwekupisa kwekupisa uye kusagadzikana kushushikana kwe substrate, kupfeka uye midziyo pasi pekupisa kwakanyanya. Kudzivirira kuunyana hakugone kungotarisa pachoto che sintering chete; Kudzora kwakarongeka kunovhara kuzara kwebasa rekugadzirira kwezvinhu, kuiswa, kuomesa, kunyura uye kutonhora kunodiwa.
Iwo akakosha ekudzora malink uye anoshanda mhinduro akanyorwa seanotevera:
I. Raw Material Substrate Control: Bvisa Kushushikana Kwemukati Pakunobva
Hunhu hwefiberglass substrate inosarudza kuoma kwekutevera kugadzirisa. Sarudza jira refiberglass rine yakaderera twist uye yakagadzikana chimiro, ine kushoma skew uye yunifomu kumucheto kusimba, iyo inoburitsa isingachinjike yekupisa shrinkage kana yapiswa.
1. Yakazara pre-dewaxing uye kupisa kugadzika: Iyo substrate inofanirwa kudzika-yepamusoro-tembiricha dewaxing uye yekupisa yekumisikidza kubvisa zvizere kuruka kushushikana kwemukati uye kudzikamisa kwayo kupisa kwekudzikira. Kusakwana kurapwa muchikamu ichi kuchakonzera kusingadzoreki kuderera kwakanyanya uye makwinya kana jira rapinda muchoto chekupisa.
2. Incoming inspection: Ongorora jira rakapfava nemachira akatwasuka kana machira ekuongorora. Cheka kana kudzosa mabhechi ane mipendero yakasununguka, mipendero yakaoma uye mabulges.
Kusaenzana kwekuputira ukobvu kunotungamirira mukusaenderana nekuderera kwePTFE yakanyungudutswa panguva yekunyungudika, zvisingadzivisiki kugadzira makwinya.
1. Multiple thin coating inopfuura panzvimbo peimwe inorema coating: Gamuchira akadzokororwa impregnation uye kuomesa maitiro ane diki, nyangwe yekuputira uremu papasi kuti uunganidze PTFE resin zvishoma nezvishoma. Dzivisa gobvu rimwe-layer coating iyo inokonzeresa kusapindirana kwemukati nekunze kwekuomesa kumhanya.
2. Kunyorova tembiricha gradient muovheni yekuomesa: Tanga nenzvimbo dzakadzika-tembiricha kuti uwedzere mvura uye zviyamuro zvishoma nezvishoma, kudzivirira kukurumidza kuumbwa kweganda repamusoro rinoteya kushushikana kwemukati kubva kune isina kuoma yemukati.
3. Synchronous active drive rollers muchikamu chekuomesa: Yese magidhi roller anotyairwa nemota uye anowiriraniswa nejira rejira rekumhanya kudzivirira kureba kutambanudza kubva pakudhonza chete.
4. Yakananga inline kuendesa kune sintering muchoto mushure mekuomesa kuti ubvise mhepo inopinda mukati. Kana kumonereka kwepakati kuchidikanwa, nyatsotonhorera jira kutanga uye nemhepo ine tension yakaderera uye dhayamita remapumburu kuti udzivise zvimedu zvechigarire zvinotakurwa muchikuva.
III. Sintering Furnace: Chaiyo Kufananidza kweTembiricha, Kuyerera Kwemhepo uye Tension
Iyi ndiyo core control segment yekudzvanya makunakuna.
1. Tension Control: Chengetedza Yakakwana Nzvimbo yeThermal Shrinkage
Kana PTFE ichinyunguduka pamusoro pekunyunguduka kwayo (~ 327°C), zvese zviri zviviri substrate nekuputira zvinoburitsa kupisa kuderera. Kunyanya tension nechisimba anotambanudza jira, kukiya zvachose deformation wrinkles pashure kutonhora; kusakwana kudhonzerana kunokonzera kuderera uye makwinya akasununguka.
Isai ma roller anodyisa muchoto chinopinza: Dyisa jira muchoto ne1% ~ 3% yakawandisa kuti uchengete mvumo yekudziya kupisa.
· Yakavharwa-loop micro-tension control mukati mechoto: Chaiyo-nguva mhinduro kuburikidza netension sensors inogadzirisa kumhanya kwemota yechikamu chega chega, kuchengetedza chete kudiki kudiki kunodiwa kuchengetedza jira rakati sandara munzvimbo yese yekushisa kwepamusoro, nejira rinoramba rakarembera pasina kurongedza.
Kutsauka kukuru kwetembiricha mukati mechoto kunokonzeresa kusawirirana pakati pemachira epakati nemapendero, ndicho chikonzero chikuru chekureba kwewavy edges uye epakati bulges.
· Chengetedza kushivirira kwekushisa mukati me ± 5 ° C: Gamuchira ma-multi-zone akazvimirira epamusoro / akadzika tembiricha kutonga uye kutenderedza mhepo inopisa kuti igadzire tembiricha yakafanana.
Inonzwisisika sintering curve: Gamuchira gradient yepreheating → yakakwirira-tembiricha sintering → inononoka kutonhora kuti igone kunyungudika zvishoma nezvishoma uye kuenzana kwePTFE pasina pakarepo kupisa kwemhepo.
· Koshesa mhepo-yemhepo sintering mavira: Mucheka unomiswa uye unofambiswa nekumusoro uye pasi-kuvhuvhuta-kuvhuvhuta kwemhepo yakachena inopisa isina ma rollers, zvakanyanya kubvisa makwinya anokonzerwa nemechani kukweshera uye kunamatira, iyo yakakwana mhinduro ye premium yepamusoro-tembiricha yekugadzira machira.
3. Kudzora Kuyerera Kwemhepo: Dzivirira Fabric Fluctuation & Stabilize Leveling
Kumhanya kwemhepo kunotenderera hakufanire kunge kwakanyanyisa, uye mafambiro emhepo achagadziriswa kudzivirira machira ane chisimba anozununguka kubva kumhepo yakananga. Alternately akarongedzerwa epamusoro uye epasi mhepo nozzles anounza yakatsiga yunifomu kuyerera kwemhepo kuitira vimbiso yekutsinhana kwekupisa pasina kukanganisa jira pamusoro.
4. Anti-Wrinkle Roller Zvikamu zveMuviri Kupararira
Isa curved banana spreader rollers kana korona spreader rollers panzvimbo dzakakosha mukati mechoto nekubuda. Iyo camber ye curved rollers inoshandisa lateral kutambanudza simba kubva pakati kusvika kumacheto kuti inyatso bvisa yakanaka longitudinal wrinkles. Ese anotakura ma roller anofanirwa kuverengerwa kuti akachinjika uye anoenderana nemazvo nguva nenguva nekukanganisa kuri pasi pe0.1mm/m.
IV. Kutonhodza & Kuisa Danho: Kiya Flat Surface zvachose
Mucheka unoramba uri thermoplastic paunobuda muchoto chinopisa; kutonhodza zvisina kunaka kunozoramba zvese zvakatanga kugadzirisa.
1. Kunonoka kutonhora zvishoma nezvishoma: Dzivisa mhepo inotonhora yakananga kudzima pakarepo mushure mekupisa kwakanyanya. Pfuura nepakati peiyo insulated inononoka kutonhora chikamu kuti udzikise tembiricha yePTFE coating uye substrate zvinyoro nyoro pazasi pekunyungudika kwekuzara kwemukati kusagadzikana kusunungurwa.
2. Chengetedza kupararira uye kuwandisa panguva yekutonhodza: Micheka inoramba ichidonha ichitonhora, saka kudyisa zvishoma uye ma roller roller achiri kudikanwa kusvika tembiricha yejira yadzika pasi pe100 ° C.
3. Kutonhora kwakazara pamberi pekupedzisira kupetwa: Ita shuwa kuti tembiricha yejira inosvika tembiricha yekamuri pasina yasara kuunganidza kupisa, ipapo mhepo ine kudzikama kwakadzikama kwemayunifomu akafuratira rolls.
V. Online Monitoring & Timely Adjustment
Rongedza vashandi vakazvipira kuti vaongorore machira ane mwenje wakasimba pachoto chechoto uye nezvikamu zvekutonhodza. Fine-tune tension, tembiricha kana kumhanya kwemutsara pakarepo kana micro-wrinkles yaonekwa. Isa isingabatanidzi infrared scanning masisitimu kuti utarise chaiyo-nguva transverse tembiricha kugovera neatomatiki maaramu ekunze-kwe-kushivirira mamiriro. Makwinya mashoma asingaperi anogona kugadziriswa pamhepo kuburikidza neanopisa calender rollers, asi kudzivirira kunoramba kuri chinhu chakakosha.
Core Summary Principle
Inokodzera yakagadzikana substrate kupisa kugadzika + yakaonda yunifomu yakawanda-layer coating + yakakwana overfeed & micro tension panguva sintering + inopindirana yakachinjika cheto tembiricha + ebetsero spreader rollers = wrinkle-isina sintered PTFE jira.
Kukanganisa kwakawanda kwemakwinya kunogona kubviswa nekunyatso kudzora kushushikana uye kufanana kwekushisa. Kunyangwe mavhiri emhepo-anotenderera anogona kuburitsa makwinya kana maparamendi ekugadzirisa akasaenderana ne substrate maitiro, ayo anoratidza kurongeka kwakazara-maitiro manejimendi anopfuura imwe chete optimization yemidziyo.
Izvo zviri pamusoro pehunyanzvi zvemukati zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.
Kana iwe uchida kuwana tsanangudzo dzakadzama, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere chepodfolio chinosanganisira PTFE yakakwirira-tembiricha jira, PTFE yakakwirira-temperature adhesive tepi, PTFE yakakwirira-temperature mesh bhandi, seamless kupisa kupisa bhandi, single-sided PTFE jira, yakakwirira-tembiricha inodzivirira pazasi inodzivirira girazi, tapota taura nesu pazasi-inodzivirira girazi.
