Faa'iidooyinka SANDUUQA 0-Ging

Marka qaybo ka mid ah giraanta 0-ga la waayo, oo cabbirka shaabadda la yaqaan halka qaybaha aan la heli karin, xirmooyinka giraanta 0-ga ah cabbirka aagga sababtoo ah waxay bixiyaan doorasho isku-dhafan iyo cabbirro O-ga ah oo loogu talagalay codsiyada kala duwan.

Qalabka 0-ring waxaa laga sameeyay noocyo tayo sare leh iyo caag nitrile ah oo waara. Faraantiyadu si fiican ayay ugu habboon yihiin sanduuqa si loogu kaydiyo meel ammaan ah.

Qalabka 0-ring waa heerka warshadaha, waxayna leeyihiin dabool dibadda ah, oo ka kooban faahfaahinta tirada, iyo cabbirka dhammaan shaabadaha 0-ring ee ku jira qayb kasta.

Qalabka 0-ring waxaa lagu bixiyaa cinjirka nitrile sababtoo ah inta badan dadka ku takhasusay isticmaalka qalabka inta ay ku jiraan biyaha cusbada leh, ozone-ku wuxuu ka caawiyaa inay weeraraan NBR. Sidaa darteed, sanduuqa Viton iyo NBR ayaa si wada jir ah u isticmaalay si ay u jebiyaan adkaanta nitrile-ka.

Sanduuqa Viton oring waa lama huraan marka la hagaajinayo tuubooyinka sababtoo ah NBR, qalabka giraanta ft valves-ka kala duwan ayaa si gaar ah u sameeya moodooyinka caanka ah.

Giraanta 0-ring waxay waxtar u leedahay yareynta kharashyada dayactirka iyo sidoo kale shaqaalaha isu-imaatinka iyadoo meesha ka saareysa mala-awaalka xulashada waqtigan badbaadinta ah.

0-ring waxay bixisaa raaxo waana fududahay in la isticmaalo, taasoo ka dhigaysa mid ku habboon in la isticmaalo oo la dayactiri karo.

Faahfaahin

Giraanta shaabadaysan (giraanta dahaarka leh ee ptfe) waxay isku daraysaa dabacsanaanta iyo sifooyinka shaabadaysan ee caagga iyo iska caabbinta kiimikada ee Teflon. Waxay ka samaysan tahay xudunta gudaha ee caagga silicone ama Viton (fluororubber) iyo Teflon FeP (polyperfluorinated ethylene propylene) ama Teflon Pfa (polytetrafluoron milmi kara) oo lagu dahaadhay isku darka, giraanta TEflon-kan caagga ah waxay bixisaa waxqabad shaabadaysan oo aad u fiican.

Giraangiraha O-ring-ka ee caagga ah si fudud loo xidho, iska caabbinta daxalka kiimikada iyo iska caabbinta gaaska ee gaaska waa mid liita, adkaanta saafiga ah ee O-ring-ka ayaa ka sarreysa in la iska caabbiyo cadaadiska laakiin dabacsanaan liidata. Giraangiraha Teflon FeP/TeFLon ee PFA O-rings waxay leeyihiin milmi wanaagsan iyo xasillooni kiimiko (haddii aysan weerarin biraha alkali, fluorine iyo qaar ka mid ah halides heerkulka sare) waxayna leeyihiin dabacsanaan wanaagsan oo u dhow giraangiraha O-ring-ka ee caagga ah, FeP/TeFLon. PFA waxay leedahay isku-darka is-goysyada oo aad u hooseeya (kaliya 0.1 ilaa 0.2) iyo iska caabbin aad u fiican oo ku saabsan is-goysyada gaaska, taas oo ka dhigaysa shaabadaha giraanta ee dahaarka leh inay ku habboon yihiin codsiyada adag. Sidaa darteed, giraanta O-ring-ka ee dahaarka leh ee ptfe, halkii ay ka ahaan lahayd giraanta O-ring-ka ee PERfluorinated ee qaali ah.

Shaqada

Dusha sare ee isku-xidhka xorta ah iyo midaysan ee dahaarka teFLon FEP/TEFLon PFA iyo xudunta gudaha ee caagga ah ayaa ka dhigaya giraanta shaabadda oo dhan inay ilaaliso shaabadda isku mid ah, dabacsanaanta iyo cadaadiska dhibic kasta oo ku taal isku-dhafka giraanta shaabadda, ayaa si isdaba joog ah loogu rakibi karaa iyadoo la adeegsanayo cadaadis joogto ah. Marka la kordhiyo cadaadiska dhexdhexaadka ah, giraanta shaabadda ayaa la cadaadiyaa guud ahaan. Giraanta shaabadda waxay la mid tahay dareere dheellitiran oo sarreeya, cadaadiska ku shaqeeyana waxaa loo gudbiyaa jihooyin kasta iyada oo aan la dhimin.

Alaab

Teflon FEP iyo Teflon PFA asal ahaan waa isku mid, laakiin teflon PFA waxay leedahay iska caabin heerkul sare oo ka wanaagsan Teflon FEP

Giraanta shaabadda ee dahaarka adag waa *, tiro badan oo codsiyo ah iyo shaabadda taagan iyo shaabadda firfircoon. Dhexroorka silikoon ee dahaarka leh ee giraanta shaabadda ee dahaarka leh guud ahaan waa ka weyn yahay, waxaana loo isticmaalaa shaabadda taagan, adkaanteeda iyo iska caabinteeda cadaadiska ayaa ka hooseysa giraanta shaabadda ee dahaarka leh ee xudunta adag.

Cadaadis

Jiritaanka dahaarka dibadda ee feP wuxuu ka dhigayaa giraanta shaabadaysan inay leedahay iska caabin adag oo wanaagsan iyo iska caabin jajaban, xudunta gudaha ee laga sameeyay caagga silikoon ama caagga Viton waxay ka dhigaysaa giraanta shaabadaysan inay wali ilaaliso dabacsanaan wanaagsan heerkulka sare ee 205℃. Isbarbardhigga waxqabadka shaabadaynta ee caagga kalrez (kabka perfluoroether), caagga Viton iyo giraanta feP ee lagu dahaadhay qalabka cadaadiska waxaa lagu muujiyay sawirka: Natiijooyinka tijaabada waxay muujinayaan in sifooyinka jireed ee caagga silikoon ama caagga Viton iyo Teflon FeP/TeFLon Sifooyinka kiimikada ee PFA waxaa la isku daray si loo sameeyo giraanta shaabadda daboolka ah, kaas oo leh cadaadis wanaagsan iyadoo la ilaalinayo sifooyinka caagga. Shaabadda giraanta dahaarka leh waxaa lagu sameeyay xakamayn tayo adag iyada oo la adeegsanayo hab gaar ah oo polymer-ka Teflon FeP si buuxda loogu dahaadhay xudunta gudaha ee caagga iyo giraanta O-ring-ka loo sameeyay dulqaadka heerka loo baahan yahay. Xogta la isticmaalay waxay muujinaysaa inaan leenahay ballanqaad tayo wanaagsan oo ku aaddan alaabtayada dahaarka, taas oo ku salaysan tijaabinta waxqabadka iyo kontaroolada adag si loo hubiyo qanacsanaanta macaamiisha iyo isticmaalka badbaadada leh ee badeecada. Marka la barbar dhigo giraanta kale ee caagga ah ama giraanta saafiga ah ee TEflon, giraanta shaabadaysan waxay leedahay shaabad aan la barbar dhigi karin iyo cimri dheer, gaar ahaan warbaahinta adag.

Iska caabbinta Daxalka Kiimikada

Teflon FEP/Teflon PFA waa qayb aasaasi ah oo ka mid ah giraanta dahaarka. Waxay leedahay iska caabin aad u fiican oo ka dhan ah nabaad-guurka kiimikada. Heerkulka adeegga caadiga ah, Teflon FeP/Teflon PFA waxaa weerara dhowr kiimikood oo keliya, kiimikooyin aan is-waafaqsanayn oo keliya ayaa halkan lagu taxay. Tusaale ahaan, saldhigyo bir ah oo xooggan, fluorine iyo qaar halides ah ayaa aan la jaan qaadi karin Teflon FeP/Teflon PFA.

Marka la kulmo Teflon FeP (heerkulka xadka lagu taliyay: 204℃/ 400F)/ Teflon PFA (heerkulka xadka lagu taliyay: 260℃/ 500F), kiimikooyin qaar oo ku jira xaddi badan ayaa la falgeli doona. Heerkulka sare, Teflon FeP/Teflon PFA waxaa mirdhiya iskudhisyo dabiici ah oo ka kooban 80% NaOH iyo KOH, hydrides bir ah sida boric acid (B2 H6), aluminium chloride, ammonia (NH3) iyo qaar ka mid ah amino acids (NH2) iyo imino (R = NH). Heerka 80f, falcelinta oksaydhka daba-dheeraada ee 70% nitric acid sidoo kale waxay noqon kartaa 80f.

Haddii loo isticmaalo xaaladahan, badeecaddu waxay ku xiran tahay tijaabo gaar ah. Marka laga soo tago kiimikooyinka la sheegay, giraanta dahaarka badanaa waa mid aan kiimiko ahayn oo ku xiran kiimikooyinka kale.

Tilmaamaha rakibidda giraanta shaabadaynta ee giraanta daboolka

1, rakibidda ama iyada oo loo marayo giraanta shaabadda ee qaybta giraanta daboolka waxay u baahan tahay siman, aan lahayn burr, jeexdin iyo xagal fiiqan, muuqaalka godka gudaha waa inuu gaaraa 20 miliinji, muuqaalka usha waa inuu gaaraa 10 miliinji.

2. Isticmaal saliid khafiif ah ama dufan si aad u saliidayso dusha sare ee giraanta shaabadaysan iyo taabashada qaybaha khuseeya.

3. Haddii giraanta shaabadaysan ee giraanta daboolka ah ay adag tahay in lagu rakibo usha, waxaa lagu dhex gelin karaa biyo kulul dhowr daqiiqo si uu u ballaariyo. Giraanta O-ga ee jilicsan oo la ballaariyay ayaa si fudud loo rakibi karaa. Ku rakib giraanta O-ga inta ay kulul tahay oo ku celi cabbirkeedii asalka ahaa marka uu qaboobo.

4. Ha si xoog leh u laabin giraanta dahaarka, haddii kale waxay sababi doontaa laalaabkii teflon waxayna saameyn doontaa isticmaalka.

Cadaadiska loo baahan yahay ee giraanta shaabadaynta waa sida soo socota

Shaabad taagan: 15% -20%

Shaabadda firfircoon: 10% -12%

Xaaladda sambabbada: 7%-8%

Qayb isdhaaf ah

Giraanta shaabadda qaybta O-qaabaysan waa badeecad caadi ah, dabcan, waxay sidoo kale samayn kartaa giraanta shaabadda qaybta laba jibbaaran iyo afargeeslaha ah, giraanta shaabaddan waxaa lagu dabaqaa dusha sare ee shaabadda waxayna u adkeysan kartaa cadaadis togan oo weyn, cabbirka rakibaaddana waxaa lagu samayn karaa giraanta shaabadda qaybta o-qaabaysan isla, laakiin waxay u baahan tahay cadaadis hoose.

Shaabadaha giraanta ee qaybta O-section-ka lagu dahaadhay aad bay u badan yihiin, shaabadaha giraanta ee qaybta laba jibbaaran ama afargeeslaha ah ayaa badanaa loo isticmaalaa xaalado gaar ah, fadlan la xiriir shirkaddayada ama qaybiyeyaasha ka hor intaadan dalban oo la tashan.

Qaybta leydi ee giraanta shaabadaynta giraanta dahaarka leh waxaa loogu talagalay iyadoo la raacayo daloolka magacaaban ee dusha sare ee shaabadaynta daboolka, gaaskan shaabadaynta ah waxaa loo yaqaan giraanta shaabadaynta leydi ee dahaarka leh, dibaddana waxaa lagu dahaadhay teFLon FEP/PFA qeexitaanno iyo dhexroor kala duwan oo ah taxanaha cabbirka shaabadaynta leydi ee dahaarka leh iyo giraanta dahaarka leh sidoo kale waa dhammaystiran tahay.
