Fluoroelastomer yi endliwile hiku humelela naswona yi vekiwile eka vuhumelerisi bya ti indasitiri hi DuPont exikarhi ka malembe yava 1950s kuringana kutlula 60 wa malembe. Yina ku tiya ka kahle swinene ka oyili, ku tiya ka mahiselo yale henhla, ku lwisana na acid leyi hlanganisiweke, ku lwisana na alkali, ku lwisana na radiation, ku lwisana na corrosion, ku lwisana swinene na oxidant, ku tiya swinene ka ti khemikhali, ku tiya kahle ka gasi, swivumbeko swa kahle swa miri na michini, na ku pfaleriwa ka gezi, ku tshikileriwa ka le hansi na ku onhaka ka nkarhi hinkwawo. Tanihi rhaba yo hlawuleka ya synthetic, yitirhisiwa ngopfu eka indasitiri ya tikhemikhali, aerospace, timovha, indasitiri ya petroliyamu, michini, electronics na swin’wana. Raba ya fluorine yina matirhelo ya kahle swinene xikan’we na ntshembo wo anama wa ku tirhisiwa. Yi tumbuluxiwile hi ku tiyimela hi rhaba ya fluoroether ya mahiselo ya le hansi ya China yi tirhisiwile hi ndlela leyi humelelaka eku endleni ka nxaxamelo wa Long March wa nxaxamelo wa swisirhelelo swa michini ya servo ya movha wo sungula, xikan’we na ku hlanganisiwa eka swihahampfhuka swa nyimpi, mathangi lamantshwa eka phayiphi ya oyili, ku pfariwa ka xirhendzevutani xa gezi na switirhisiwa swin’wana. Eka ku tirhisiwa ka vaaki ka swiphemu swa timovha, ku andza siku na siku, eka nsimu ya tiindasitiri hakatsongo-tsongo ku khutaza ku tirhisiwa ka rhaba ya fluorine.

Hambi leswi rhaba ya fluorine yinga na ku tiya swinene eka swihangalasamahungu xikan’we na mahiselo yale henhla tani hileswi swinga boxiwaka laha henhla, kuna swin’wana leswinga tolovelekangiki na swiphiqo eka maendlelo yo lulamisa naku humelerisa switirhisiwa swa rhaba ya fluorine, laha leswi tolovelekeke kunga swilo leswi feke leswi hisiweke loko swikatsa, ku pfuleka ku basisiwa ti sticky rollers, minkarhi yin’wana ti dots letintsongo to basa ta kumeka loko ku tsemiwa naku kambela endzhaku kaloko filimi yi humesiwile, switirhisiwa swa olova ku swi endla ku handzuka, ku hunguteka naku pandzeka, ku hisa makumu, kuna swirhabyani eka swihlanganisi, ku pfumaleka ka rhaba, ku onhaka ka xiendliwa, ku tshukatshuka lokukulu ka mould na swiendlakalo swin’

Ku hlamula eka ku nga tolovelekangi loku nga laha henhla eka maendlelo ya vuhumelerisi, swintshuxo leswi landzelaka swi endliwile.

Nhlamuselo 1. Swilo leswi feke swa rhaba ya fluorine leyi pfanganisiweke

Xivangelo xa ku khumbana ka rhaba ya xiaki na switirhisiwa swo tshwuka swa sulphur kumbe swo tshwuka swa sulphur, mabindzu yo tala a ya na muchini wo hlawuleka wo basisa rhaba ya fluorine, hakanyingi ku basisa swilo swin’wana swa rhaba yo tshwuka ya sulfur, ku basisa a ku le ku endliweni, kumbe swiaki leswi thyakeke hi xihoxo hi sulphur yellow kumbe mati, leswaku swi nga hlanganisiwa na promoter ya rhaba ya fluorine leyi vangiwaka hi ku scorching, kumbe ku ntirho wa mati ku endla leswaku fluorine rubber surface activation decomposition. Ntlhantlho, muchini wo hlawuleka lowunene, loko swi nga ri tano, wu fanele wu tlhela wu va eka ku hundzuriwa ka rhaba ya fluorine loko ku nga si basisiwa, wu fanele ku basisiwa hi ku helela baffle plate na plate ya swilo, papalata hi ku helela ku khumbana na mati na sulphur yellow, swiaki ku cheriwa switirhisiwa swo hlawuleka, nchumu wun’we xipunu, ku sivela ku cross-contamination. Hlayisa calcium hydroxide na magnesium oxide swi pfaleriwile naswona swi lulamerile ku tirhisiwa.

Point 2. Xiendlakalo xa xirhendzevutani xo namarhela

Ngopfu ngopfu eka maendlelo yo hlanganisa eka muchini wo pfula, swilo swa rhaba swi phutseriwe swinene eka roller yale ndzhaku, kutani hi nkarhi wun’we swi phutseriwe emahlweni na le ndzhaku ka ti rollers timbirhi, leswi endlaka leswaku swilo swa khale swa rhaba swinga hundzuki ku basisiwa, naswona leswinga hundza na agent leyi engeteriweke swikandziyeriwa hiku olova eka ti flakes naswona swiwa, leswi endlaka leswaku kuva na ku hangalaka lokunga ringaniki. Xivangelo nkulu xa fluorine rubber material leyi namarhelaka eka ti rollers i Menny yale hansi kumbe molecular yale hansi ya fluorine rubber. Ntlhantlho wa xiphiqo lexi iku hlawula rhaba yoka yinga swekiwanga leyingana viscosity ya kwalomu ka 70, naswona kutirhisa rhaba yoka yinga swekiwanga leyingana ku hangalasiwa ka molecular weight leyintsongo, kutani u chela nhlayo yintsongo ya Brazilian wax kumbe fluorine wax kumbe polyethylene ya molecular weight yale hansi eka formula, leswinga tlhela swi tlhantlha xiendlakalo xa sticky roller.

Nhlamuselo 3. Malunghana na swivati ​​leswintsongo swo basa eka rhaba yo hlanganisa

Swivangiwa hi ku hangalaka kun’wana ka powder ya fluorine rubber compounding agent ayi fani, kumbe hikokwalaho ka powder moisture caking, kufana na acid absorbers calcium hydroxide, magnesium oxide na diatomaceous earth, barium sulfate, etc., solution, ku sivela compounding agent ndzhongho naku tiyisisa maendlelo ya thin pass.

Point 4. Xiendliwa lexi xa olova ku xi handzula

Xivangelo, kungava burr yo tiya swinene, ku tsemeta loko ku handzuriwa, kumbe mould na tight ngopfu, ehandle ka xivumbeko swiphemu swa burr swi khomiwile eka xivumbeko, swi olova kusuka eka xiendliwa na burr loko swinga se handzula, matimba lawa yanga ringaniki loko kusunguriwa xivumbeko, swi olova ku handzula xiendliwa. Minkarhi yin’wana ku lulamisiwa ka xivumbeko xa xivumbeko xa xivumbeko xa rough, kutani nchumu lowu namarhelaka wu namarhela eka xivumbeko, naswona loko vulcanization yi herile, swivanga swiphiqo swo hluvula xivumbeko naswona swi handzula xitirhisiwa hiku olova. Ku engetela kwalano, mahiselo ya vulcanization yale henhla swinene, leswinga tlhela swi endla leswaku switirhisiwa swiva na brittle naswona swi olova ku handzula. Eka ku nga tolovelekangi loku nga laha henhla, swi nga tlhantlhiwa kusuka eka swiyenge leswi landzelaka: ku kongoma ka ku lulamisiwa ka mould kufanele kuva kahle cavity roughness Ra ehansi ka 0.8, fit gap ayifanelanga kuva yikulu swinene, vulawuri bya mahiselo ya vulcanization lebyi siyiweke exikarhi ka 170 degrees byi kahle, naswona ku pima ka swilo swa rhaba swifanele kuva swiri kahle.

Point 5. ku pandzeka Xiphiqo xa ku hunguteka na

Swivangiwa hi ntshikelelo lowu susiwaka loko xivumbeko xi pfuriwile, kuhunguteka ka rhaba ya fluorine, naswona xiphemu xa burr xi khomelela eka xivumbeko lexinga na vuandlalo exikarhi, kutani exikarhi ka xiphemu xa xiendliwa na burr swihumelerisa matimba yo koka, leswaku xiendliwa na burr swi avana, loko xivala xa ku pandzeka xi andlariwile kuya eka xiphemu xa xiendliwa, swivanga xiendlakalo xa kuhunguteka na ku pandzeka. Ntlhantlho iku hunguta mahiselo ya vulcanization hindlela leyi faneleke, hlawula Menny viscosity eka kwalomu ka 70 [ML1+4] 121 degrees, kasi mold fit degree yifanele kuva leyi faneleke, kungari ku olova ngopfu naswona yi tiya swinene.

Point 6. Edge yi fana na ku hisa

I mahiselo ya vulcanization yale henhla swinene, ngopfu ngopfu switirhisiwa swo tiya, leswi faneleke ku hunguta mahiselo ya vulcanization yanga hluriwa.

Point 7. Kuna swikoweto eka nhlangano

I t swivangiwa hi lap xiphemu xa adhesive material ayi hlanganisiwanga hiku hetiseka, kumbe hikokwalaho ka adhesive strip yina thyaka kumbe oil fouling, solution iku hlayisa preformed adhesive strip eka vuhlayiselo, ku fambisiwa, loading glue yi basile, ku sivela ku thyakisa.

Mhaka 8. Ku pfumaleka ka glue

Swi fambelana na xivumbeko xa xivumbeko na liquidity ya glue. Xivumbeko lexi pfalekeke xi tala ku humesa ku pfumaleka ka glu ku tlula xivumbeko lexi pfulekeke. Ntlhantlho iku lulamisa liquidity ya rhaba naku pfula hole yo humesa moya eka mold cavity.

Nhlamuselo ya 9. Ku onhiwa ka swikumiwa

Swi vangiwa hi fluorine rubber shrinkage rate yikulu, endzhaku ko vumba xiendliwa shrinkage anisotropy, coefficient ya thermal expansion ya rhaba eka matlhelo yo hambana yi hambanile, maendlelo mambirhi ya vulcanization ya ta vumba cross-linking yo engetela, ngopfu ngopfu xiphemu xa vulcanization ehansi ka sulphur, vulcanization timbirhi ta xiendliwa, ku onhaka loku nga erivaleni swinene, leswaku ku nyikiwa ku hlanganisiwa loku heleleke eka nkarhi wa nkarhi wa vulcanization, ku papalata vulcanization yimbirhi ya deformation ya xiendliwa.

Point 10.Mold stain xiendlakalo lexikulu

Hi ntolovelo hi tirhisa 26 type fluorine rubber, phenol vulcanization system, eka endlelo ra vulcanization yita endliwa HF, i acid yo tiya swinene, yina mbuyelo lowukulu wo bola eka xivumbeko, formula yo engetela acid absorbent i ku tswonga HF leyi endliweke, ku sivela ku thyakisa ka xivumbeko. Ntlhantlho iku tirhisa calcium hydroxide leyi ringaneleke na magnesium oxide kuya hi formula, mpimo hi xitalo i 6 wa swiphemu na 3 wa swiphemu, naswona Brazilian wax yinga cheriwa eka formula, leyi yinga rhurhela eka vuandlalo bya rhaba hinkarhi wa vulcanization kuva yi endla film kuva yi sivela mould kuva yi thyakisiwi.

Swilo leswi tolovelekeke swa khume leswi tolovelekeke eka vuhumelerisi na ku lulamisiwa ka rhaba ya fluorine swinga tlhantlhiwa hi magoza yohambana hambana.
