Indlela iFiberglass Thermal Shrinkage echaphazela ngayo PTFE Tape Dimensional Stability

A I-PTFE tape ecuthekayo, i-curls, okanye i-warps ngexesha lokusetyenziswa kukungaphumeleli kwentsimi eqhelekileyo. Unobangela wengcambu uhlala ubuyela emva kwipharamitha enye: izinga lokucutheka kwe-thermal ye-fiberglass substrate..

Ngexesha le-PTFE i-sintering kwi-360-400 ° C kunye nokunyanga okunamathelayo kwi-150-200 ° C, Ilaphu le-fiberglass lifumana ukwanda kwe-thermal kwaye, ngokubaluleke ngakumbi, ukushwabana okungenakubuyiseka kuxinzelelo lokuluka olushiyekileyo. Ukuba olu xinzelelo alupheliswanga ngaphambi kokugubungela, luba sisiphene esifihliweyo - esibangela ukuba i-tape iyancipha, i-curl, okanye i-delaminate xa ishushu.

I-Aokai PTFE isebenzisa i-fiberglass substrates eseti ngokupheleleyo ubushushu ukuphelisa le ngxaki. Eli nqaku lichaza ingcambu ye-shrinkage ye-thermal, iimpembelelo zayo kwinqanaba ngalinye lokucubungula, kunye nesisombululo esisisiseko: i-preheat-set-set fabric kunye ne-<0.5% iyancipha kwi-400 ° C.

Unobangela Wengcambu – Uxinzelelo lweNtsalela oluvela ekuLukweni

Ukucutheka kwe-Thermal ngokusisiseko kuvela kuxinzelelo lwentsalela lwangaphakathi oluqokelelwe ngexesha lomzobo wefiber yeglasi kunye nokulukwa kwelaphu. Ilaphu le-Fiberglass ngaphandle kokumiselwa kobushushu obugcweleyo liya kucutheka ngokungenakujikwa lakuba lishushu ngaphezu komda wokukhululwa koxinzelelo (ukuncipha okumangalisayo kuqala ngaphezulu kwe-300 ° C).

Naluphi na uxinezeleko olungakhutshwanga ngokupheleleyo okanye olungathintelekiyo lokucutheka luba yeyona ngxaki ifihlakeleyo ebangela imilinganiselo yeteyipu engazinzanga. Olu xinzelelo 'lutshixiwe' kwisakhiwo selaphu ngexesha lokuluka kwaye lukhupha kuphela xa lufudunyezwe kwiqondo lobushushu elaneleyo.

Impembelelo Ngexesha le-PTFE Sintering-Inqanaba Elibalulekileyo

Ubushushu be-PTFE sintering bufikelela kwi-360-400 ° C, bugqithise kakhulu ubushushu bokuqala be-fiberglass shrinkage thermal, okwenza eli nqanaba libe yinto egqibayo yokusebenza komda.

1. Uxinzelelo lokucutheka olutshixiweyo ludala iziphene ezifihlakeleyo

Ukuba icutshungulwe phantsi koxinzelelo oluphantsi, ilaphu le-fiberglass licutheka ngokukhululekileyo kwaye ngokugqithisileyo, okukhokelela kubude obunganeno kunye nobubanzi bobubanzi. Ukuba uxinzelelo olugqithisileyo lusetyenziswa ekuthinteleni ukucutheka, imicu yeglasi yoluswa ngenkani. Malunga ne-380 ° C, i-PTFE etyhidiweyo iyangena kwaye isonge imicu eyoluliweyo; emva kokupholisa kunye nokumila, ukuthambekela kokucutheka okufihlakeleyo kutshixelwe ngokusisigxina ngaphakathi kwi-substrate njengoxinzelelo olukhulu olushiyekileyo. Nje ukuba itheyiphu iphinde ifudunyezwe kwiinkqubo zamva, olu xinzelelo lushiyekileyo lubangela ukuncipha kwe-substrate kwaye bonakalise ngokuthe ngqo ukuzinza kwe-dimensional.

2. Ukungalingani kwe-substrate flatness kujongela phantsi ukufana kwengubo

Amazinga okucutheka okuthe cwaka kuzo zonke iizowuni zelaphu ezahlukeneyo (umzekelo, umphetho xa uthelekiswa nombindi) ngexesha le-sintering trigger deformations kuquka i-wavy edges, i-cupped margins, kunye namaqhuma angaphezulu . Umphezulu we-substrate ongalinganiyo ukhokelela kubunzima obungalinganiyo bokuncamathelisa kwiinkqubo ezilandelayo, kubangele lula amaqamza omoya okanye ukuncamathela okungalunganga ngexesha le-lamination, kunye nokuwohloka ngokungangqalanga kokuzinza komgangatho kunye nokusebenza kweeteyiphu ezigqityiweyo.

Impembelelo Ngexesha lokuNyangwa kweAdhesive-Secondary Stress Relief

Iinkqubo zokubambelela (i-silicone i-adhesive-sensitive adhesives, i-acrylic adhesives, njl.) iphilisa kwi-150-200 ° C. Eli qondo lobushushu lisezantsi kunoluhlu lwe-sintering kodwa lwanele ukwenza intsalela yoxinzelelo olutshixekileyo ngaphakathi kwi-substrate, izisa iziphumo ezibi ezininzi.

1. I-shrinkage yesibini ibangela iziphene zomhlaba kunye nokuphambuka kwe-dimensional

Xa ungena kwi-oven yokunyanga, uxinzelelo lwe-shrinkage eseleyo ngaphakathi kwe-substrate ikhupha kwaye ibangele ukucutha kwe-tape enokulinganiswa. Oku kukhokelela ekubeni:

• Ukunciphisa ububanzi obugqithisileyo

• I-Micro-cracks, ukuthungwa kwe-orenji yamaxolo, okanye ukungaphumeleli kokubambisana kumphezulu wokunamathela (njengoko ukushwabana kwenzeka ngaxeshanye nokunyanga)

• Ukuguquguquka okude kubukhulu bokuncamathelisa kunye nokushwabana kweentambo zokukhulula (ngenxa yokungahambelani phakathi kwesantya sokushwabana kwelaphu kunye nesantya sokutyabeka somgca werola)

2. I-Thermal curling isusa ukuchaneka kokucubungula

I-substrate layer idibanisa ngokusebenzayo phantsi koxinzelelo lwe-residual evuthayo, ngelixa i-adhesive layer enyangeke ngokupheleleyo ine-coefficient eyahlukileyo yokwandiswa kwe-thermal, idala ukungahambi kakuhle koxinzelelo phakathi kwemigangatho emibini. I-tape curls ngokukhawuleza xa ihlanjululwe kwi-liners yokukhulula okanye ibonakaliswe kubushushu ngexesha lokusetyenziswa - ukusilela ukubeka isicaba kunye nokulahlekelwa ukulawulwa kwe-dimensional kunye nokusebenza.

Ukukhutshwa koxinzelelo oluqhubekayo ngexesha lokusetyenziswa kokuphela - ukungazinzi kwexesha elide

Uxinzelelo lokucutheka olushiyekileyo olungapheliswanga ngokupheleleyo ngexesha lokuncamathelisa luyaqhubeleka kwimveliso egqityiweyo. Ngaphantsi kwe-masking ephezulu yokushisa, i-lamination ye-thermal, okanye i-thermal cycling iimeko (umzekelo, i-260 ° C i-powder coating), i-tape iyancipha ngokuthe ngcembe kwaye ngokuqhubekayo.

Iziphumo:

• Imida yokufihla ishenxisiwe (imigca yetywina iyashukuma)

• Ukunyuswa komphetho okanye ukungaphumeleli kokubambelela

• Ilahleko epheleleyo yokuzinza kwe-dimensional

Yiyo loo nto ezinye iiteyiphu zisilela kwintsimi nasemva kokudlula uhlolo lokuqala - uxinzelelo olufihlakeleyo lukhutshwa kancinci ngokuhamba kwexesha kunye nokuvezwa kobushushu.

Isisombululo esingundoqo-Susa i-Shrinkage phambi kokuSintering

Ukwenza iiteyiphu zokuncamathelisa ze-PTFE ezizinzileyo, ukunyanzeliswa koxinzelelo ngexesha lokulungiswa akunako ukusombulula imiba yokuncipha ngokusisiseko. Ukususwa ngokupheleleyo kwe-fiberglass shrinkage kufuneka kuphunyezwe kumthombo.

1. Indlela ye-Aokai PTFE

1. Sebenzisa ubushushu obupheleleyo (i-pre-shrunk) i-fiberglass base cloth - izinga lokunciphisa i-thermal elawulwa ngokungqongqo ngaphantsi kwe -0.5% phantsi kweemeko zovavanyo ze-400 ° C × imizuzu ye-10 (imigangatho eqinile ekhoyo kumabakala e-premium).

2. Yongeza i-high-temperature pre-filling process ngaphambi kokufakwa okanye ukugquma kwe-PTFE-ukuvumela ilaphu le-fiberglass ukuba lizalise i-shrinkage yamahhala kwaye likhulule ngokupheleleyo lonke uxinzelelo lwangaphakathi ngaphambi kokungena kwindawo ye-sintering.

2. Isiphumo

Nje ukuba isantya sokucutheka sobushushu belaphu le-fiberglass sicuthiwe, ukuguquguquka kobukhulu ngexesha lokucwina okulandelayo kunye nokuncamathelisa kuya kuvela kuphela kulwandiso lobushushu kunye nokucutheka kweresin kunye neeleya zokuncamathelisa - ngobungakanani obuncinci kakhulu kunokuncipha okushiyekileyo okuqhutywa luxinzelelo. Oku kuqinisekisa ngokusisiseko:

• Uzinzo lweDimensional (ubude nobubanzi)

• Umphezulu othe tyaba

• Ukumelana nokushisa kunye nokuthembeka kwexesha elide

I-Aokai PTFE ikhetha kuphela ubushushu obugcweleyo obusetiwe kwi-fiberglass substrates ezinamazinga ashicilelweyo okucutheka. Sinokubonelela ngedatha yovavanyo ngokweemfuno zabathengi.

IsiShwankathelo – Umgaqo waPhambi kokucutheka

I-Aokai PTFE icebisa i-fiberglass esele isetyenzisiwe kunye ne-shrinkage <0.5% yazo zonke izicelo ezibaluleke kakhulu. Kubathengi abafuna ubungakanani obuzinzile kakhulu, sinikezela ngamabanga eprimiyamu ngokucutheka <0.3% kwi-400°C.
