Ekizigo kya PTFE kinyungibwa 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 ne Teflonhigh-temperaturecl othmanufacturer–JiangsuAokaiNewMaterialTechnologyCo.,Ltd., okukwatagana wakati w’ebibiri kutera okutuukibwako okuyita mu kusiba eby’omubiri n’okusiba ebyuma, okwongerwako n’obujjanjabi bwa kemiko primer n’ebikosa ebikolwa eby’okukwatagana 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 olulimu obutuli.Bwe PFEemulsion oba dispersion efumbiddwa oba esiigiddwa ku fiberglass fabric, PTFE eyingira mu bbanga n’ebifo ebikwatagana wakati w’ebiwuzi.Oluvannyuma lw’okukala n’ebbugumu eringi intering(nga 360–400°C),obutundutundu bwa PTFE busaanuuka mu firimu egenda mu maaso, nga bunyweza ebibumbe by'obuwuzi nga'enkoba ezitabalika.'Naye, okwesigama ku nkola eno yokka kikyavaamu amaanyi g'okukwatagana agakoma, era okutwalira awamu kyetaagisa emitendera egy'okugatta.

2.SilaneCouplingAgentPretreatment (Eddagala okuzimba omutala) .

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 ebisiiga 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 obubi 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 obulungi obunnyogovu n’okunyweza okunyweza ku fibers za giraasi, era nga zisobola okugumira ebbugumu ly’ekisambi eriddakoPTFE mu nkola wakati.

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

Layer eno eya primer etuuka ku kukwatagana kwa kemiko n’okusiba okw’omubiri n’olugoye lwa fiberglass olulongooseddwa-ekirungo ky’okuyunga, n’ekola layeri y’enkyukakyuka ennene.Omuzannyi 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(ethylenpropylene) oba PFA(perfluoroalkoxy) firimu ,ezirina ebifo eby’okusaanuuka 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 ya PTFE n’olugoye lwa fiberglass, ebuguma era n’enyigirizibwa, n’oluvannyuma lw’okunyogoza, n’enkyukakyuka ey’amaanyi.

Ebintu bingi eby’ebbugumu eringi ebitambuza oba emisipi n’ebintu eby’olususu 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 okuwera okuddirira n’emulsion ya PTFE 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 waliwo amaanyi ag’omunda n’amaanyi ag’okusiba ag’amaanyi.
