Ekizigo kya PTFE kiyungibwa kitya ku substrate y’olugoye lwa fiberglass mu lugoye lwa Teflon olw’ebbugumu eringi?

Olugoye Lw'okusiiga PTFE ku TeflonOlugoye olw'ebbugumu erya wagguluByekwata Kitya Ku Lugoye lwa Fiberglass?

PTFE(polytetrafluoroethylene)erina amaanyi amatono ennyo ag'okungulu era nga gamanyiddwa nnyo ng'ekintu 'ekitali kikwata'.N'olwekyo,tesobola kuyungibwa butereevu mu kemiko ku lugoye lwa fiberglass ng'ebizigo ebya bulijjo.Ekeberebwa Teflonhigh-temperaturecl othmanufacturer–JiangsuAokaiNewMaterialTechnologyCo.,Ltd., okukwatagana wakati w’ebibiri kutera okutuukibwako okuyita mu kusiba omubiri n’okusiba ebyuma, okwongerwako n’obujjanjabi bwa kemiko primer n’ebikosa ebiva mu kukwatagana n’okusaanuuka.

Enkola ezenjawulo ez’okusiba olugoye olwa Teflon olw’ebbugumu eringi okusinga mulimu bino wammanga:

1.MechanicalInterlocking(Okukwatagana mu mubiri) . Eno y’enkola esinga obukulu.Olugoye lwa fiberglass lwennyini lwe lugoye olw’obuziba.Bwe PFEemulsion oba okusaasaana kufumbiddwa oba okusiigiddwa ku lugoye lwa fiberglass,PTFE eyingira mu bbanga n’ebifo ebikwatagana wakati w’ebiwuzi.Oluvannyuma lw’okukala n’ebbugumu eringi intering(nga 360–400°C),thePTFEparticlesmeltintoacontinuous film, firmly grippingthe fiberbundleslikecountless'anchohooks.'Naye, okwesigama ku nkola eno yokka kikyavaamu amaanyi g'okukwatagana agakoma, era okutwalira awamu kyetaagisa emitendera egy'okugatta.

2.SilaneCouplingAgentPretreatment (Eddagala okuzimba omukutu) .

Eno kumpi nkola enkulu ey’emifaliso egy’omutindo ogwa waggulu egyaPTFEfiberglass.Ekitundu ky’emifaliso gya fiberglass esooka kulongoosebwa n’ekirungo ekigatta silane (nga saminosilane,epoxysilane, n’ebirala):

Enkomerero emu eya silane(siloxygroup),oluvannyuma lw’okusaanuusa amazzi, esobola okukwatagana mu ngeri y’eddagala n’ebibinja bya hydroxyl(-OH)ku ngulu w’ebiwuzi bya giraasi;

Ekirala, nga zirimu ebibinja ebikola ebiramu, zisobola okusalako okuyunga oba okukwatagana n'amaanyi n'ebitundu ebinyweza mu primer erimu fluorin mu kiseera ky'okufunyisa oba okusiiga okuddirira.Kino kizimba 'molecularbridge'wakati w'enkolagana z'ebiramu n'ebiramu.

3.Eddagala lyaPrimerTransitionLayer

Okusiiga obutereevuPTEkivaamu okunywerera okubi oluvannyuma lw’okusiba, primeri eziweereddwa amazzi zitera okusooka okusiigibwa ku lugoye lwa fiberglass.Okutwalira awamu layeri eno eya primer erimu:

Adhesiveresins: Nga poliyamide-imide(PAI),polyphenylenesulfide(PPS),polyethersulfone(PES),oba polyetheretherketone(PEEK),ezirina okunyweza obulungi n’okunyweza okunyweza ku fibers za giraasi, era nga zisobola okugumira ebbugumu ly’ekisambi eriddakoPTFE mu nkola ekwatagana.

PTFEmicropowder: Okukakasa nti PTFE eyasooka n’esembayo ku muzannyi asobola okugatta wamu.

Layer eno eya primer etuuka ku kukwatagana kwa kemiko n’okusiba kw’omubiri n’olugoye lwa fiberglass olulongooseddwa-ekirungo ky’okuyunga, n’ekola layeri ey’enkyukakyuka ennene.Omuzannyi ono PTFE olwo n’agatta n’ekitundu kya PTFE mu primer mu kiseera ky’okusiba, bwe kityo mu ngeri etali butereevu n’atuuka ku maanyi g’okunyweza aga waggulu.

4.Hot-MeltAdhesiveFilmLamination (Enkola ya Lamination) Enkola eno, ekozesebwaJiangsuAokaiNewMaterialTechnologyCo.,Ltd.,ekozesebwa okukola bondpre-formed,thickPTFEfilmtofiberglassfabric.KubangaPTFEerina extremelyhighmeltviscosity(approxim ately10⊃1;0–10⊃1;⊃2;Pa·s),thardlyflowsevennga ebuguma waggulu w'ekifo kyayo eky'okusaanuuka, so directhot-pressbonding isnot possible.Amelt-processable'hot-meltadhesive'mustbeused,typically: FEP(ethylenepropylene) oba PFA(perfluoroalkoxy) firimu ,ezirina ebifo eby’okusaanuuka ebya wansi okusingaPTFE(nga 260–310°C).Oluvannyuma lw’okusaanuuka, zisobola okufukirira engoye za fiberglass ne zisaasaana/okusaanuuka nePTFEfil msurface.Mu nkola, firimu yaFEP/PFA eteekebwa wakati wa firimu yaPTFE n’olugoye lwa fiberglass, ebuguma n’enyigirizibwa, n’oluvannyuma lw’okunyogoza, omuguwa ogw’amaanyi ne gukyusiddwa.

5.GradientStructureviaEmitendera mingi egy’okufukirira n’okusiba

Ebintu bingi eby’ebbugumu eringi ebitambuza oba emisipi n’ebintu eby’oluwuzi lw’ebizimbe bikolebwa mu nkola y’okufukirira emirundi mingi: Okufunyisa okusooka kukozesa okusaasaana okwa dilutePTFE okulimu ebisiba n’ebiyunga, ekisobozesa primer okuyingira mu buziba mu bibumbe by’obuwuzi. Oluvannyuma lw’okufukirira, okufukirira okuwerako okuddirira n’emulsion yaPTFE ennongoofu n’emitendera egy’okusengejja egy’omuddiring’anwa gikolebwa, ekivaamu obulongoofu bwaPTFE obweyongera ku ngulu. Kino kitondekawo layeri y’enkyukakyuka mu butonde okuva mu fabricto ya fiberglassfabrictothepurePTFE, nga erimu amaanyi ag’omunda n’amaanyi ag’okusiba ag’amaanyi.

Mu bufunzi

Mu bufunze, okukwatagana wakati w'okusiiga kwa PTFE n'engoye za fiberglassfabricinTeflon ez'ebbugumu eringi si'okusiiga'–kizibu (enkola ya yinginiya ey'enkola): okuyita mu kunyweza eby'omubiri okutwala emirandira mu biwuzi, okuyita mu cou plingagents ne primer okutuuka ku kemiko bonding ne transition, era okuyita mu bbugumu erya waggulu intering okumaliriza okusaanuuka-okugatta kwa filmmlayers.Singa purePTFEzaali zisiigiddwa butereevu, layer yonna yandisekula nelear emu.
