Fluoroelastomer ekoleddwa bulungi era n’eteekebwa mu kukola mu makolero nga kkampuni ya DuPont mu makkati g’emyaka gya 1950 okumala emyaka egisukka mu 60. Eriko okugumira amafuta okulungi ennyo, okugumira ebbugumu eringi, okugumira asidi omungi, okugumira alkali, okugumira emisinde, okugumira okukulukuta, okugumira okw’amaanyi mu oxidant, okugumira eddagala okw’amaanyi, okunyweza ggaasi okulungi, eby’obugagga ebirungi eby’omubiri n’ebyuma, n’okuziyiza amasannyalaze, okunyigirizibwa okutono n’okukyukakyuka okw’olubeerera. Ng’omupiira ogw’enjawulo ogw’obutonde, gukozesebwa nnyo mu makolero g’eddagala, mu by’omu bwengula, mu by’emmotoka, mu makolero g’amafuta, ebyuma, ebyuma n’ebirala. Fluorine rubber erina omulimu omulungi ennyo ate nga esuubira okugikozesa mu ngeri egazi. Ekoleddwa mu ngeri eyeetongodde eya China eya fluoroether rubber ey’ebbugumu eritono ebadde ekozesebwa bulungi mu kukola Long March series of launch vehicle servo mechanism seals, wamu n’okukuŋŋaanyizibwa mu nnyonyi ennwaanyi, ttanka empya ku payipu y’amafuta, okubikka ku circuit y’amasannyalaze n’ebikozesebwa ebirala. Mu nkozesa ya civil ku bitundu by’emmotoka, okweyongera buli lunaku, mu kisaawe ky’amakolero mpolampola okutumbula enkozesa ya fluorine rubber.
Newankubadde nga kapiira ka fluorine agumira bulungi nnyo emikutu n’ebbugumu eringi nga bwe kyayogeddwa waggulu, waliwo ebitali bya bulijjo n’obuzibu mu nkola y’okulongoosa n’okufulumya ebintu ebikolebwa mu kapiira ka fluorine, nga mu bino ebya bulijjo mulimu ebintu ebifu ebyokeddwa nga bitabuddwa, ebizingulula ebizingulula ebinyweza ebizingulula, oluusi obutundutundu obutono obweru busangibwa nga basala n’okukebera nga firimu emaze okufuluma, ebintu byangu okukola okukutuka, okukendeera n’okukutuka, okwokya ku mbiriizi, waliwo obubonero ku biyungo, obutaba na kapiira, okukyukakyuka kw’ebintu, okusiiga ebikuta eby’amaanyi n’ebintu ebirala, ebikosa omutindo gw’ebintu. Omutindo gw’ebintu gukosebwa.
Mu kwanukula ebitali bya bulijjo ebyo waggulu mu nkola y’okufulumya, eby’okugonjoola bino wammanga byakolebwa.
Ensonga 1. Ebintu ebifu ebya fluorine rubber ebitabuddwa
Ensonga lwaki ekirungo kya kapiira kikwatagana n’ebintu ebya kiragala ebya salufa oba ebya kyenvu kya salufa, amakampuni mangi tegalina kyuma kya kapiira kya fluorine eky’enjawulo ekirongoosa, emirundi mingi erongoosa ebintu ebirala ebya kapiira ebya kyenvu ebya salufa, okuyonja tekuli mu kifo, oba ebirungo ebifuuse ekivundu mu butanwa ne kiragala kya salufa oba amazzi, bwe kityo ne kisobola okugattibwa ne promoter wa kapiira ka fluorine ekiva ku kukwatagana, oba the omulimu gw’amazzi okukola okuvunda kw’okukola ku ngulu kwa kapiira ka fluorine. Solution, ekyuma ekisinga obulungi eky’enjawulo, bwe kitaba bwe kityo, era kirina okuba mu kukyusa kapiira ka fluorine nga tonnalongoosa, kirina okuba nga kiyonjo ddala baffle plate ne material plate, weewale ddala okukwatagana n’amazzi ne sulphur yellow, ebirungo okusiiga ebikozesebwa eby’enjawulo, ekintu ekijiiko, okuziyiza cross-contamination. Kuuma calcium hydroxide ne magnesium oxide nga bisibiddwa era nga byetegefu okukozesebwa.
Ensonga 2. Ekintu ekiyitibwa sticky roller phenomenon
Okusinga mu nkola y’okutabula ku kyuma ekiggulawo, ekintu kya kapiira kizingiddwa bulungi mu muzingo ogw’emabega, oba mu kiseera kye kimu nga kizingibwa nga tekunnabaawo n’oluvannyuma lw’emizingo ebbiri, ekivaamu ekintu ekya kapiira ekyali tekisobola kukyuka kulongoosa, ate eky’oluvannyuma n’ekirungo ekigattibwako kyangu okunyigirizibwa mu bikuta ne kigwa, ekivaamu okusaasaana okutali kwenkanankana. Ensonga enkulu lwaki ekintu kya kapiira kya fluorine okunywerera ku biwujjo ye Menny entono oba molekyu entono mu kapiira ka fluorine. Ekigonjoola ekizibu kino kwe kulonda kapiira embisi nga alina obuzito nga 70, n’okukozesa kapiira embisi nga bulina ensaasaanya y’obuzito bwa molekyu enfunda, n’oluvannyuma n’ossaamu akatono aka Brazilian wax oba fluorine wax oba low molecular weight polyethylene mu formula, ekiyinza n’okugonjoola ekizibu kya sticky roller phenomenon.
Ensonga 3. Ebikwata ku butundutundu obutono obweru mu kapiira akagatta
Kiva ku kusaasaana kwa butto okumu okwa fluorine rubber compounding agent si kwa kimu, oba kiva ku butto obunnyogovu caking, nga acid absorbers calcium hydroxide, magnesium oxide ne diatomaceous earth, barium sulfate, n’ebirala, solution, okuziyiza ekirungo ekigatta obunnyogovu n’okunyweza enkola ya thin pass.
Ensonga 4. Ekintu kino kyangu okukutuka
Ekivaako, kiyinza okuba burr enzito ennyo, okusala nga okutula, oba ekikuta n’ekinywevu ennyo, okuva mu kibumba ebitundu by’ekibumbe bikwatiddwa mu kibumba, byangu okuva ku kivaamu ne burr nga tebinnakutula, amaanyi agatali ga bwenkanya nga otandika ekibumba, kyangu okukutula ekintu. Oluusi okulongoosa mu kisenge ky’ekikuta kiba kikalu, oba ekintu ekisiiga kinywerera ku kibumba, era vulcanization bwe kumalibwa, kireeta obuzibu okuggyako ekibumbe ne kikutula ekintu mu ngeri ennyangu. Okugatta ku ekyo, ebbugumu ly’okufuuka vulcanization liri waggulu nnyo, ekijja n’okuleetera ebintu okufuuka ebikutuka era ebyangu okukutuka. Ku butabeera bwa bulijjo waggulu, kiyinza okugonjoolwa okuva mu bintu bino wammanga: obutuufu bw’okukola ekikuta bulina okuba obulungi obukaluba bw’ekituli Ra wansi wa 0.8, ekituli ekikwatagana tekirina kuba kinene nnyo, okufuga ebbugumu ly’okuwunyiriza okulekebwa wakati wa diguli 170 kirungi, n’okupima ebintu bya kapiira kulina okuba okutuufu.
Ensonga 5. n’okukutuka Ekizibu ky’okukendeera
Kiva ku puleesa eggyibwawo nga ekibumbe kigguddwawo, fluorine rubber okukendeera, era ekitundu kya burr ne kisibira mu kibumba nga kungulu kuli wakati, kale wakati w’ekitundu ky’ekintu n’ekibumbe ne kivaamu empalirizo y’okusika, olwo ekintu n’ekibumbe ne bikutuka, ekizimbe ky’enjatika bwe kigaziwa okutuuka ku kitundu ky’ekintu, kireeta ekintu eky’okukendeera n’okukutuka. Ekigonjoola kwe kukendeeza ku bbugumu ly’okufuuka vulcanization mu ngeri esaanidde, okulonda Menny viscosity mu diguli nga 70 [ML1+4] 121, ate nga diguli y’okukwatagana kw’ekikuta erina okuba esaanidde, si kusumululwa nnyo era nga nnywevu nnyo.
Ensonga 6. Edge eringa okwokya
It is the vulcanization temperature is too high, naddala ebintu ebinene, ebisaanira okukendeeza ku vulcanization temperature esobola okuvvuunukibwa.
Ensonga 7. Waliwo obubonero ku kiyungo
I t is due to the lap part of the adhesive material is not completely fused together, oba olw’okuba nti adhesive strip erina obucaafu oba oil fouling, eky’okugonjoola kwe kukuuma preformed adhesive strip mu kutereka, okutambuza, okutikka glue nga nnyonjo, okuziyiza obucaafu.
Ensonga 8. Obutabeera na kalaamu
Kikwatagana n’ensengekera y’ekibumbe n’obuziba bwa kalaamu. Ekibumbe ekiggaddwa kitera okuvaamu obutaba na kalaamu okusinga ekibumbe ekiggule. Ekiyinza okugonjoolwa kwe kutereeza amazzi ga kapiira n’okuggulawo ekituli ekifulumya empewo mu kisenge ky’ekibumbe.
Ensonga 9. Okukyukakyuka kw’ebintu
Kiva ku fluorine rubber shrinkage rate munene, oluvannyuma lw’okubumba ekintu shrinkage anisotropy, omugerageranyo gw’okugaziwa kw’ebbugumu kwa kapiira mu ndagiriro ez’enjawulo gwa njawulo, bbiri vulcanization enkola ejja kukola cross-linking ey’enjawulo, naddala ekitundu kya vulcanization wansi wa sulphur, bbiri vulcanization y’ekintu, okusingawo okweyoleka deformation, bwe kityo okuwa full-linking mu kiseera kya vulcanization time, okwewala vulcanization bbiri ez’okukyukakyuka kw’ekintu.
Point 10.Ekikuta ky'amabala eky'amaanyi ekintu
Okutwalira awamu tukozesa ekika kya 26 fluorine rubber, phenol vulcanization system, mu nkola ya vulcanization ejja kukolebwa HF, ye acid ya maanyi nnyo, erina kinene corrosive effect ku kibumba, formula y’okugattako acid absorbent kwe kunyiga HF ekoleddwa, okuziyiza obucaafu bw’ekikuta. Ekigonjoola kwe kukozesa calcium hydroxide ne magnesium oxide ebimala okusinziira ku nkola, okutwalira awamu ddoozi eba ya bitundu 6 n’ebitundu 3, ate Brazilian wax asobola okugattibwa ku formula, asobola okusenguka n’agenda ku ngulu kwa kapiira mu kiseera ky’okufuuka vulcanization okukola firimu okuziyiza ekikuta okubeera ekikyafu.
Ebizibu ekkumi waggulu ebitera okubaawo mu kukola n’okulongoosa kapiira ka fluorine bisobola okugonjoolwa nga tuyita mu bipimo eby’enjawulo.
