Buza

Ngaphambi kokugquma kwe-PTFE, ukufakwa kwe-resin, okanye ukulanywa, Ilaphu lefiberglass kufuneka lomiswe kwangaphambili. Injongo isenokuba kukususa ukufuma, okanye kunokubandakanya ukutshisa i-ajenti yokulinganisa i-textile (i-dewaxing), okanye ukufudumeza ilaphu kwiqondo lobushushu elizinzileyo ngaphambi kokugquma. Injongo nganye ifuna ubushushu obuhlukeneyo kunye nezicwangciso zexesha.

Iiparamitha ezingalunganga zingakhokelela ekungangeni kakuhle, ukudibanisa okubuthathaka, ukuthungwa kwelaphu, ukulahlekelwa kwamandla - okanye i-scrap epheleleyo.

I-Aokai PTFE inamava abanzi kwi-glass fiber processing. Esi sikhokelo sichaza amacandelo amathathu onyango oluphambili, amanqanaba abo okushisa afanelekileyo, ukulawula ixesha, kunye neengcebiso ezisebenzayo kwiziphumo ezihambelanayo.

IiNjongo eziNtathu eziPhambili zoNyango kunye noLuhlu lwazo lobushushu

Injongo yoNyango	Uluhlu lobushushu	Injongo engundoqo	Usetyenziso oluqhelekileyo
Ukususwa kobumanzi (eyona ixhaphakileyo)	105°C – 120°C	Susa amanzi e-adsorbed ngaphandle kokonakalisa ii-agent zokulinganisa	I-Lamination, i-PTFE / i-silicone yokubeka, i-prepreg layup
Ukukhutshwa kwewaxing / ukucocwa kobushushu (ukususwa kobukhulu)	300°C – 450°C	Yitshise ngokupheleleyo imilinganiselo yelaphu (isitatshi, iPVA, njl.njl.)	Iinkqubo ezifuna umgangatho ococekileyo kakhulu: ukufakwa kwe-resin, unyango lwekhemikhali
Ukufudumeza kwangaphambili kwinguqu yenkqubo	60°C – 100°C	Phakamisa ubushushu belaphu lokugquma okanye ukufakwa	Imigca eqhubekayo yokugquma, ngaphambi kokuba i-glue dip tanks; ikhusela i-resin viscosity ukunyuka kwilaphu elibandayo

Ukususwa kobumanzi rhoqo - Eyona Nkqubo iQhelekileyo

Eli linyathelo eliqhelekileyo lokumisa kwangaphambi kokumiswa kwelaphu elininzi ngaphambi kokugquma okanye ukulanyiswa. Injongo kukukhupha amanzi ngokucokisekileyo ngelixa ukhusela ii-agent zokulinganisa ezibamba iifiber kunye.

1. Ukulawula ubushushu

Kumalaphu e-elektroniki ngokubanzi kunye nawomeleza: gcina i-105°C - 120°C.
Kwiimpahla eziphathwe nge -silane coupling agents : gcina izinga lokushisa elingaphantsi kwe-110 ° C ukuze ugweme ukuphula iibhondi zokudibanisa.
Ukutenxa kweqondo lobushushu ngaphakathi kwi-oven kufuneka kulawulwe ngaphakathi kwe- ±5°C ukuthintela ukufudumeza kwendawo.

2. Ulawulo lwexesha (ngokusekwe kubunzima belaphu)

Ubunzima belaphu	Ixesha elicetyiswayo
Ilaphu elibhityileyo (<100 g/m²)	10 - 15 imizuzu
Ilaphu eliphakathi & elinzima (200 – 400 g/m²)	20 – 30 imizuzu
Ilaphu elishinyeneyo / imathi (>600 g/m²)	1 - 2 iiyure okanye ngaphezulu

Ikhrayitheriya yokuphelisa: Ubunzima obuqhubekayo buphunyezwa xa umahluko wobunzima phakathi kwemilinganiselo emibini elandelelanayo ungaphantsi kwe-0.1%. Amalaphu aqengqelekayo, uwaxhome ngokukhululekileyo okanye usebenzise imicu ye-spacer ngexesha lokumisa ukunqanda ingxaki yomile ngaphandle kodwa ngaphakathi kumanzi.

3. Amanqaku olawulo aphambili

I-oven kufuneka ibe ne -dehumidification ngenkani . Vula iivalvu zomoya omtsha ukukhupha umoya ofumileyo kwangethuba.
Musa ukulayisha ngaphezulu i-oven; qinisekisa ukuhamba komoya malunga nomqulu okanye ishidi ngalinye.

Ukucocwa kweDewaxing kunye ne-Thermal - kwiMimandla ecocekileyo kakhulu

Xa ilaphu kufuneka likhululeke ngokupheleleyo kwi-organic sizeng agents (umzekelo, phambi kokufakwa kwe-resin ephezulu yokusebenza kwi-aerospace okanye i-composites yobushushu obuphezulu), ukucocwa kwe-thermal kuyafuneka.

1. Ukulawula ubushushu

Ukuguquguquka kunye nenqanaba lokutshaya: malunga ne-300°C. Ifuna ioksijini eyaneleyo kunye nokukhupha umsi osebenzayo.
Inqanaba lokudinwa kwentsalela: kancinci kancinci unyusa amaqondo obushushu aye kuma 380°C – 450°C kwaye ubambe, ukukhupha ngokupheleleyo intsalela yekhabhoni.
Ungaze udlule kwi-500 ° C - kungenjalo i-fiberglass ngokwayo iya kuba brittle kwaye yonakaliswe.

2. Ukulawula ixesha

Kwiziko zokushisa eziqhubekayo, hlengahlengisa isantya sokuhamba kwelaphu ukuze uqinisekise ukuba ilaphu lihlala kwindawo enobushushu obuphezulu kangangemizuzu emininzi ukuya ngaphezulu kweshumi, kuxhomekeke kubunzima belaphu. Amalaphu anzima afuna ukuvezwa ixesha elide.

3. Iinqobo zokwamkela

Ilahleko xa kucinywa (LOI) iya kuba ngaphantsi kwe-0.1%. Lo ngumgangatho wegolide.
Uvavanyo olulula lwentsimi: Basa ikona yelaphu ngesibane. Izinto ezifanelekileyo azivelisi umsi omnyama okanye ivumba elikhethekileyo, kunye nentsalela yothuthu oluncinci.
Ilaphu elifanelekayo libonakala limhlophe okanye ligcina umbala walo wokuqala, ngaphandle kwamabala amnyama okanye imicu etyheli.

4. Amanqaku okulandelela

Ilaphu le-fiberglass ene-dewax linomsebenzi omphezulu ophezulu . Yitshintshele kwinkqubo elandelayo yokukhulelwa kwangoko, okanye utywine kwaye upakishe ngokufanelekileyo ukuthintela ukufunxwa kwakhona kokufuma kunye nokungcoliseka.

Ukufudumeza Ngaphambi Kokugquma - Ukuzinza kweNkqubo

Ngaphambi kokufaka i-PTFE emulsion okanye i-silicone yerabha yokwaleka, ilaphu linokufuna ukufudumeza okuthambileyo kwiqondo lobushushu elizinzileyo.

1. Iiparamitha zokufudumala

Seta iqondo lobushushu: 60°C – 80°C , ngaphezulu kancinane kwindawo enombethe ukuthintela ukomiswa komphezulu okhawulezayo.
Ixesha lokuhlala: ngokuqhelekileyo imizuzwana emininzi ukuya kwimizuzu enye okanye emibini usebenzisa i-infrared okanye ii-oveni zomoya ezishushu - ngokwaneleyo nje ukuzisa ilaphu kwiqondo lobushushu ekujoliswe kulo.

2. Izikhokelo zokusebenza ezisebenzayo

Thatha ubushushu belaphu lokwenyani njengomgangatho, hayi ubushushu bomoya we-oveni. Sebenzisa ithemometha ye-infrared okanye izixhobo zokulinganisa ubushushu ezikhaphayo ukujonga ixesha lokwenyani.
Ukuhamba komoya okulinganayo kunye nokujikeleza - ukuhanjiswa komoya oshushu kuqinisekisa ukomisa ukusebenza kakuhle. Isantya somoya esilinganayo siqinisekisa ukusasazwa kobushushu kububanzi belaphu.
Uvavanyo lokuqala lwesampulu: Iibhetshi ezahlukeneyo zinokusebenzisa iiarhente zokulinganisa ezahlukeneyo. Thatha iisampuli ezincinci kwaye zomise kumaqondo okushisa ahlukeneyo (105 ° C, 120 ° C, 130 ° C, njl.). Qwalasela ukuguga komphezulu kunye nokutshintsha kwamandla ukuqinisekisa ubuninzi bobushushu obukhuselekileyo kwibhetshi nganye.

Ugcino Emva Kokomisa – Thintela UkuNgcona kwakhona

Ilaphu elomileyo, ingakumbi ilaphu eligalelwe iwax, liyihygroscopic kwaye lingcoliseka lula.

Ukuba akusetyenziselwanga ukusetyenziswa ngokukhawuleza, tywina kwiingxowa ze-aluminium foil kunye ne-desiccants.
Enye indlela: gcina kwigumbi lokomisa elinobushushu obungaphantsi kwe 30°C kunye nokufuma okungaphantsi kwe 40%.
Ifestile yokusetyenziswa ecetyiswayo: kwiiyure ezi-4 ukuya kwezi-8 emva kokumisa iziphumo ezilungileyo. Ngaphandle koko, yome kwakhona ngaphambi kokusetyenziswa.

Ingcebiso ye-Aokai PTFE: Kwizicelo ezithembeke kakhulu (i-aerospace composite, ukufakwa kwe-voltage ephezulu), sincoma ukusebenzisa ilaphu ngoko nangoko emva kokumiswa okanye kwiiyure ezi-2.

IsiShwankathelo – IiParameters eziPhambili ngokuKhawuleza

Inkqubo	Ubushushu	Ixesha (ngokobunzima)	Iitshekhi ezibalulekileyo
Ukususwa kobumanzi	105-120°C (<110°C yonyango lwe-silane)	I-10-30 min (incinci ukuya phakathi); 1-2h (inzima)	Ubunzima obuqhubekayo (<0.1% utshintsho); ukuphelisa ukufuma ngenkani
Ukukhutshwa kwewaxing / ukucocwa kwe-thermal	300-450°C (soze>500°C)	Eziliqela ukuya kwi-10+ imiz	LOI <0.1%; akukho msi omnyama; mhlophe/imbonakalo ecocekileyo
Ukufudumala ngaphambi kokutyabeka	60-100°C	Imizuzwana ukuya kwi-2 min	iqondo lokushisa ngelaphu; ukuhamba komoya okufanayo
Ukugcinwa kwasemva kokumisa	<30°C, <40% RH	Sebenzisa kwiiyure ezingama-4-8	Iingxowa ezitywiniweyo okanye igumbi lokumisa

I-Aokai PTFE ibonelela ngeenkcukacha zokomisa kwangaphambili kuwo onke amalaphu ethu e-fiberglass. Kwizicelo ezibalulekileyo, sinokubonelela ngelaphu elomiswe ngaphambili kwaye livalwe ngevacuum elungele ukusetyenziswa kwangoko. Qhagamshelana nathi ngeeparamitha zokumisa ngokwesiko ngokusekelwe kuhlobo lwelaphu lakho kunye nenkqubo elandelayo.

Lo mxholo ungentla unikwe ngu I-Jiangsu Aokai yeZixhobo eziNtsha zeTekhnoloji Co., Ltd.

Ukuba unqwenela ukwazi ngakumbi malunga neenkcukacha ezicacileyo, iimeko zesicelo kunye nezisombululo ezilungiselelwe uluhlu lwethu olupheleleyo lwemveliso, kubandakanywa amalaphu e-PTFE anobushushu obuphezulu, iiteyiphu ze-PTFE ezinobushushu obuphezulu, amabhanti e-mesh ye-PTFE, amabhanti omatshini wokubopha angenamthungo, ilaphu le-PTFE elinamacala elinye, amalaphu anobushushu obuphezulu obunganyangekiyo, kunye ne-fiberglass enganyangekiyo.
