Bamka kiimikaad, doorashada saxda ah waa bamka, doorashada khaldan waa shilka bamka kiimikada ee valve iyo qalabka dhuumaha ee cabbiraadaha ka hortagga barafka Warshadaha batroolka iyo kiimikooyinka ayaa ku jira meel aad muhiim u ah dhaqaalaha qaranka, iyo bamka habka kiimikada sida qalabka muhiimka ah ee taageeraya aad iyo aad baa loo fiirsaday. Sababtoo ah sifooyinka adag ee dhexdhexaadinta kiimikada, oo ay weheliso shuruudaha sii kordhaya ee ilaalinta deegaanka, sidee baan u dooranaa nooca bamka kiimikada? Waxa ay tahay in fiiro gaar ah loo yeesho iyo wixii la mid ah ayaa si gaar ah muhiim u ah. Xiaobian si ay kaagala hadasho doorashada bamka kiimikada waa in ay fiiro gaar ah u yeelato arimaha! Ogow mid: iska caabinta daxalka Daxalka had iyo jeer wuxuu ahaa mid ka mid ah khataraha qalabka kiimikada. Haddii aad taxaddar la'aan tahay, qalabku wuu dhaawacmi doonaa, cuslaaguna wuxuu sababi doonaa shilal ama xitaa masiibo. Marka loo eego tirakoobyada laxiriira, qiyaastii 60% waxyeelada qalabka kiimikada waxaa sababa daxalka, markaa waa in aan marka hore fiiro gaar ah u yeelano dabeecadda sayniska ee xulashada walxaha marka la dooranayo bamka kiimikada. Caadi ahaan waxaa jira isfaham la'aan ah in birta aan la taaban karin ay tahay "qalab", iyada oo aan loo eegin wax kasta oo dhexdhexaad ah iyo xaaladaha deegaanku ay hayaan birta aan la taaban karin, tani waa mid aad khatar u ah. Waxyaabaha soo socda ee qaar ka mid ah dhexdhexaadinta kiimikada caadiga ah si ay uga hadlaan qodobbada ugu muhiimsan ee xulashada alaabta: 1, sulfuric acid, Sida mid ka mid ah warbaahinta xooggan ee daxalka ah, sulfuric acid waa wax aad u badan oo muhiim ah oo warshadeed oo ceeriin ah. Heerkulka kala duwan iyo heerkulka sulfuric acid ee kala duwanaanshaha daxalka walxaha waa weyn yahay, fiirsashada in ka badan 80%, heerkulku wuxuu ka yar yahay 80 ℃ sulfuric acid. socodka xawaaraha sare ee sulfuric acid, oo aan ku habboonayn qalabka bamka; Birta caadiga ah sida 304(0Cr18Ni9), 316(0Cr18Ni12Mo2Ti) sidoo kale waxay leedahay isticmaal xaddidan oo loogu talagalay dhexdhexaadinta sulfuric acid. Sidaa darteed, bamka bamka ee gudbinta sulfuric acid sida caadiga ah waxaa laga sameeyaa bir silikon sare leh (dhibitaanka iyo processing adag), daawaha sare birta (No. 20 alloy), laakiin ay adag tahay processing iyo qaali, sidaas darteed waxa aan la jeclayn by dadka. Alaabta caagga ah ee Fluorine waxay leedahay caabbinta sulfuric acid aad u wanaagsan, waa Akademiyada Shiinaha ee Sayniska Shanghai Institute of Organic Chemistry patent material, Tijaabada Akademiyada Sayniska ee Shiinaha ayaa cadaysay in aysan jirin wax dhexdhexaad ah oo kiimiko ah oo ka falcelin kara, sidaa darteed isticmaalka fluorine ayaa safan. bamka (F46) waa doorasho dhaqaale oo badan. 2, hydrochloric acid Inta badan walxaha birta ah uma adkeysanayaan daxalka hydrochloric acid (oo ay ku jiraan noocyo kala duwan oo walxo bir ah), ferrosilicon-ka kooban molybdenum sidoo kale waxaa loo isticmaali karaa 50 ℃, 30% ka hooseeya hydrochloric acid. Si ka duwan qalabka birta ah, inta badan alaabta aan biraha ahayn waxay leeyihiin iska caabin wanaagsan oo daxalka ah ee hydrochloric acid, sidaas darteed bamka caagga ah ee safan iyo bamka caagga ah (sida balaastikada injineernimada, balaastikada fluorine, iwm.) ayaa ah doorasho wanaagsan oo lagu qaado hydrochloric acid. 3, Nitric acid Biraha guud inta badan si degdeg ah ayey ugu daxalantahay nitric acid, birta aan la taaban karin waxaa si weyn loogu isticmaalaa agabka caabbinta nitric acid, dhammaan xajmiyada nitric acid ee heerkulka qolka waxay leeyihiin iska caabin daxaleed oo wanaagsan, waxaa xusid mudan in molybdenum ay ku jirto birta aan la taaban karin (sida. 316, 316L) iska caabbinta daxalka ee nitric acid kama roona birta caadiga ah (sida 304, 321), marmar xitaa ka sii daran. Heerkulka sare ee nitric acid, walxaha daawaha caagga ah ee fluorine ayaa badanaa la isticmaalaa. 4, acetic acid, Waa mid ka mid ah maaddooyinka ugu daxalka badan ee ku jira asiidhka organic. Birta caadiga ah waxay si dhab ah ugu daxaloobaysaa aashitada acetic ee dhammaan heerarka iyo heerkulka. Birta aan lahayni waa wax aad u wanaagsan oo u adkaysta aashitada, iyo molybdenum 316 birta aan lahayn waxa kale oo loo isticmaali karaa heerkul sare iyo uumi acetic acid. Heerkulka sare ee acetic acid ama ay ku jirto dhexdhexaad kale oo daxalaysa iyo shuruudo kale oo adag, waxay dooran kartaa birta aan lahayn alloy sare ama bamka caagga ah ee fluorine. Sida CQB bamka magnetic, CQ ahama bamka magnetic. 5. Saldhig (sodium hydroxide) Guud ahaan daxalka ma aha mid aad u xoog badan, laakiin xalalka alkali guud ayaa soo saari doona crystallization, si aad u dooran kartaa nooca FSB fluoroalloy alkali bamka leh shaabadda farsamada ee silica graphite 169 wax. 6. Ammonia (ammonia hydroxide) Daxalka inta badan biraha iyo kuwa aan biraha ahayn ee dareeraha ammonia iyo ammonia (ammonia hydroxide) waa mid khafiif ah. Kaliya naxaasta iyo naxaasta daawaha waa inaan la isticmaalin. Waqtigaan, CQF injineernimada bamka magnetka caagga ah, FSB fluorine alloy bamka centrifugal ayaa ka fiican. 7. Biyaha milixda ah (biyaha badda) Birta caadiga ah ee ku jirta xalinta chloride sodium iyo biyaha badda, heerka daxalka biyaha milixdu maaha mid aad u sarreeya, guud ahaan waa in la isticmaalo ilaalinta rinjiga; Dhammaan noocyada kala duwan ee birta aan daxalka lahayn ayaa sidoo kale leh heerka daxalka isku midka ah oo aad u hooseeya, laakiin waxay keeni karaan daxal maxalli ah oo ay ugu wacan tahay ions chloride, sida caadiga ah 316 birta aan daxalka ahayn ayaa ka fiican. 8, khamriga, ketones, esters, ethers dhexdhexaad ah khamriga caadiga ah sida methanol, ethanol, ethylene glycol, propylene glycol, ketone, sida dhexdhexaad ah, waxaa jira dhammaan noocyada kala duwan ee methyl esters dhexdhexaad ah, ethyl ester, ethers media sida methyl ether, butyl ether, ay aasaasiga ah ma daxalka xoog badan, si dhan u dooran kartaa ahama caadiga ah, xulashada la taaban karo waa in sidoo kale sida ay shuruudaha guryaha dielectric iyo la xiriira samayn doorasho macquul ah. Intaa waxaa dheer, waxaa habboon in la ogaado in ketone, ester iyo ether ay ku milmayaan noocyo kala duwan oo caag ah, oo iska ilaali khaladaadka markaad dooranayso qalabka wax lagu xiro. Waxaa lagu talinayaa in la doorto bamka magnetka caagga ah ee fluorine ee xiran. Waxa jira warbaahin kale oo badan oo aan mid mid lagu soo bandhigi karin, marka la soo koobo, xulashada agabku waa in aanay noqon mid aan kala sooc lahayn oo indho la’aan ah, waa in ay la tashadaan macluumaad badan oo khuseeya ama ay bartaan khibrad qaan-gaar ah. Fiiro gaar ah laba: Dhibaatada shaabaddii bamka kiimikaad Ma jirto wax daadintu waa daba-galka daa'imka ah ee qalabka kiimikaad, waana shardigan ka qayb qaatay kordhinta codsiga bamka magnetic. Si kastaba ha ahaatee, weli waxaa jira waddo dheer oo lagu gaaro si loo gaaro wax daadinta, sida nolosha adeegga ee bamka go'doominta bamka magnetic, daxalka walxaha, isku halaynta shaabada taagan iyo wixii la mid ah. Qaar ka mid ah macluumaadka aasaasiga ah ee ku saabsan xidhidhiyaha ayaa si kooban loo soo bandhigay sida soo socota: 1. Foomka wax lagu xidho Si loo xidho xidhidhiyaha joogtada ah, inta badan waxa jira laba nooc oo ah gaasaska iyo giraanta wax lagu xidho, giraanta xidhitaanka waxa si weyn loogu isticmaalaa O-ring. Shaabada firfircoon, shaabadda bamka kiimikada, ayaa si dhib leh loo isticmaalaa in la siiyo mudnaanta shaabad farsamo, shaabad farsamo iyo weji keliya iyo weji labalaab ah, dheellitirka iyo moodelka aan dheellitirka lahayn, qaabka dheellitirka ayaa ku habboon shaabadda dhexdhexaadinta cadaadiska sare (sida caadiga ah Waxaa loola jeedaa cadaadiska waa ka weyn yahay 1.0 MPa), double dhamaadka wejiga shaabadeynta mashiinka waxaa loo isticmaalaa heerkulka sare, fududahay in la crystallization, viscosity, iyo dhexdhexaad ah sunta kacsan oo ay ku jiraan qayb, The mashiinka double-dhamaadka ah shaabad waa in lagu duro dareere go'doomin godka shaabadda, iyo cadaadisku guud ahaan wuu ka sarreeyaa cadaadiska dhexdhexaadka ah 0.07 ~ 0.1MPa. 2. Shayga lagu xidho kiimikooyinka bimka magnetic static shabada guud ahaan waxay isticmaashaa caag fluorine, kiisaska gaarka ah waxay isticmaalaan kaliya walxaha PTFE; Qalabaynta maadada farsamada farsamada giraanta firfircooni waa mid aad u muhiim ah, maaha daawaynta adag ee daawaynta adag ayaa ka fiican, qiimaha ayaa sarreeya hal dhinac, labaduba ma laha qallafsanaan liidata maaha mid macquul ah, markaa way fiicantahay in la takooro si waafaqsan sifooyinka. ee dhexdhexaadka ah. Fiiro gaar ah saddex: dhibaatada viscosity Viscosity ee dhexdhexaadka ah ayaa saameyn weyn ku leh waxqabadka bamka. Marka viscosity-ku kordho, qalooca madaxa bamka ayaa hoos u dhacaya, madaxa iyo qulqulka xaaladaha shaqada ee wanaagsan ayaa hoos u dhacaya, halka korontadu ay u kacdo si waafaqsan, markaa waxtarka ayaa hoos u dhacaya. Guud ahaan, halbeegyada muunadku waa waxqabadka gaadiidka biyaha nadiifka ah, beddelaadna waa in la sameeyaa marka la qaadayo warbaahinta viscous (fadlan tixraac jaantuska beddelka ee habboon ee isugeynta sixitaanka ee viscosity kala duwan). Si loo qaado dheecaanka viscosity-ka sare, koollada iyo dareeraha viscouska, waxaa lagu talinayaa in la doorto bamka hoobiye. Mabda'a xulashada bamka Ku rakibida qalabka, si loo go'aamiyo isticmaalka bamka iyo cabbirada waxqabadka oo dooro nooca bamka. Doorashadani marka hore waa in ay ka bilaabataa doorashada nooca iyo qaabka bamka, markaa mabda'a ah in la doorto bamka? Maxaa ku salaysan? 1. Samee nooca iyo waxqabadka bamka la doortay inuu buuxiyo shuruudaha socodka qalabka, madaxa, cadaadiska, heerkulka, gunnada cavitation, nuugista iyo hababka kale ee habka. 2, waa inuu buuxiyaa shuruudaha sifooyinka dhexdhexaadka ah ee gudbinta gubanaya, qarxa, sunta ama dhexdhexaadka qiimaha leh ee bamka, shaabadda shafka ayaa looga baahan yahay inuu noqdo mid la isku halleyn karo ama aan lahayn bamka daadinta, sida bamka gawaarida magnetic (ma jiro shaabad shaft ah, isticmaalka gooni-u-goosadka magnetic drive aan toos ahayn; Si loo gudbiyo bamka dhexdhexaadka ah ee daxalka ah, qaybaha isku dhufashada ayaa looga baahan yahay inay isticmaalaan walxaha u adkaysta daxalka, sida bamka caagga ah ee fluorine; Gudbinta bambooyin ay ku jiraan qayb dhexdhexaad ah oo adag, qaybaha convection-ka ayaa looga baahan yahay inay isticmaalaan qalab u adkaysta, iyo marka loo baahdo, shaabadda shafka waxaa lagu dhaqaa dareere nadiif ah. 3, shuruudaha farsamada ee kalsoonida sare, qaylada hoose, gariir yar. 4. Si sax ah u xisaabi qiimaha wax soo gelinta ee bamka iibsiga. 5, gaadiidka dhexdhexaadka ah daxalka (sida "sulfuric acid uruursan, nitric acid"), gaadiidka ololaya iyo dhexdhexaad ah walxaha qarxa, isticmaalka deegaanka waa in aanay yeelan wax wasakh ah: dooran kartaa bamka magnetic, sida "CQB taxane magnetic bamka, IMD bamka magnetic taxane, haddii aad u baahan tahay in aad is-priming, dooran kartaa FZB fluorine bamka is-priming caag ah 6. Bamka centrifugal IHF iyo FSB centrifugal bamka ayaa leh sifooyinka xawaaraha sare, mugga yar, miisaanka fudud, hufnaan sare, socodka weyn. qaab-dhismeedka fudud, ma pulsation ee faleebo, waxqabadka xasilloon, hawlgalka fudud iyo dayactirka ku habboon, sida isticmaalka xaaladaha aan shuruudo gaar ah, dooran kartaa bamka centrifugal waa ka fiican 7, gudbinta ee bamka dhexdhexaadka ah walxaha adag, qaybaha convection yihiin Loo baahan yahay in la isticmaalo qalabka u adkaysta: UHB bamka hoobiye ayaa ah doorashada ugu wanaagsan ee walxaha, UHB iska caabbinta daxalka u adkaysta xirashada matooriyaha ee heerka ugu sarreeya ee caagagga injineerinka cusub ee UHBWPE, waa miisaan unugyo aad u sarreeya oo la beddelay (in ka badan 5) milyan) polyetylen. Balaastikada dhexdooda, waxay leedahay iska caabin aad u fiican. Isbarbardhigga tijaabada ayaa muujinaya in caabbinta xirashada ay aad uga badan tahay tan birta, waxayna leedahay astaamo u gaar ah sida iska caabbinta saameynta, caabbinta gurguurta iyo iska caabinta daxalka wanaagsan (oo la barbar dhigi karo F4), iyo sidoo kale aan la isku dhejin. 8. Marka heerka dareeraha dhexdhexaadka ah uu ka hooseeyo booska rakibaadda ee bamka: FZB fluoroplastic bamka is-hormarinta waa in la doortaa. Haddii aad sidoo kale u baahan tahay inaad la kulanto sifooyinka matoorka magnetic, ZMD fluoroplastic bamka magnetic is-priming magnetic waa la dooran karaa 9, marka loo eego qalooca waxqabadka bamka si aad u dooratid qaab qeexan oo ka sii wanaagsan: marka shuruudaha isticmaalka ee miiska cabbirka waxqabadka ma heli karo qaabka ku habboon wuxuu tixraaci karaa qalooca waxqabadka bamka si uu u doorto nooca bamka ugu habboon.
