Payipu za PFA n’emiggo egy’okuweta: okwekenneenya enkozesa y’amakolero ey’ebintu eby’amaanyi -Ebikozesebwa mu kukola fluoroplastic .

Nga ekitundu ekikulu eky’ekika kya fluoroplastic, PFA (perfluoroalkoxy resin) ekozesebwa nnyo mu kemiko, semikondokita, eddagala n’emirimu emirala olw’obutebenkevu bwayo obulungi obw’eddagala, okuziyiza ebbugumu eringi n’omugerageranyo gw’okusika omuguwa omutono. Nga ebitundu ebikulu ebiyunga, omulimu gwa payipu za PFA n’emiggo egy’okuweta egy’okuwanirira gikwata butereevu ku kwesigika n’obulamu bw’empeereza y’enkola. Ekiwandiiko kino kijja kwekenneenya ebifo eby’ekikugu ebya payipu za PFA n’emiggo egy’okuweta okuva mu nsonga ssatu: eby’obugagga by’ebintu, enkola z’okukozesa n’enkola z’okuweta.

1. Ebirungi ebikulu ebiri mu payipu za PFA .

Payipu za PFA zisikira obuziyiza bw’okukulukuta kwa PTFE (polytetrafluoroethylene), ate mu kiseera kye kimu ne zilongoosa amazzi g’okulongoosa nga zireeta ensengekera ya perfluoroalkoxy, esobole okuyungibwa mu ngeri etali ya buzibu nga esaanuuka mu bbugumu. Obuwanvu bwayo obuwanvu-Ebbugumu ly’okukozesa terimu -200℃okutuuka ku +260℃, era ebbugumu lyayo erimpi-okugumira term liyinza okutuuka ku 300℃, ekiyinza okutuukiriza ebyetaago by’embeera y’okukola ennyo. Okugatta ku ekyo, PFA erina obuweweevu obw’amaanyi ennyo ku ngulu (RA value eyinza okuba wansi wa 0.1μm), ekikendeeza obulungi okuziyiza amazzi n’okukendeeza ku bulabe bw’okugerageranya, era nga ya njawulo nnyo mu nkola z’okutuusa amazzi mu bulongoofu obw’amaanyi.

2. Dizayini ekwatagana ey’emiggo gya PFA welding .

PFA Welding Rods ne Payipu zikozesa ensengekera y’emu ey’ebintu ebikulu okukakasa okukwatagana kw’eddagala n’amaanyi g’ebyuma eby’ebiyungo ebiweereddwa. Emiggo egy’okuweta egy’omutindo ogwa waggulu-gilina okutuukiriza emitendera gino wammanga: Omuwendo gw’okusaanuuka gukwatagana ne payipu (ebiseera ebisinga 3-5g/10min), ebirimu obucaafu biba wansi wa 10ppm, era amaanyi g’okusika gasinga oba okwenkana 20MPa. Special specification welding rods era zisobola okutumbula creep resistance nga ziteekamu carbon fiber oba glass microbeads, ezisaanira embeera za puleesa enkulu.

3. Ebikulu ebifuga ebifo eby’enkola ya welding .

PFA Pipe Welding okusinga yeettanira enkola bbiri: hot melt butt welding oba flaring socket. Hot melt welding yeetaaga okufuga okutuufu ku bbugumu (ebiseera ebisinga 350-400℃), puleesa (0.1-0.3MPa) n’obudde bw’okunyogoza (obutono obutakka wansi wa ddakiika 15) okwewala ebiwujjo oba okuweweevu okunnyogoga. Flaring welding yeetaaga flaring tool accuracy okutuuka ku ±0.05mm n’okukuuma embeera ennywevu okumala eddakiika 1-2 oluvannyuma lwa payipu okuyingizibwa. Kikulu okumanya nti obunnyogovu bw’embeera y’okuweta bulina okuba wansi wa 60% okuziyiza okutondebwa kw’obutuli obuva ku kufuuwa amazzi.

Olw’obwetaavu obweyongera obw’okukulukuta-ebintu ebiziyiza mu nnimiro y’amakolero, obwetaavu bw’akatale ka payipu za PFA n’emiggo egy’okuweta bikyagenda mu maaso n’okugaziwa. Okukuguka mu kulonda okutuufu ne tekinologiya w’okuweta kifuuse ekitundu ekikulu mu kukakasa enkola empanvu-term stable operation of the fluid system. Mu biseera eby’omu maaso, olw’okutumbula tekinologiya w’okukyusa ebintu, obusobozi bw’okukozesa ebintu bya PFA mu mbeera ezisingako obuzibu bujja kwongera okufulumizibwa.
