Shaandhada Saliidda Mesh-ka ee Flange 304 ee aan lahayn birta 82x100

S1: Sidee si habboon loogu nadiifiyaa loona ilaaliyaa shaandhada saliidda ee birta aan lahayn ee 304?

A1:(1) Habka nadiifinta: Isticmaal mashiinka nadiifinta ultrasonic (soo noqnoqoshada 40kHz, heerkulka ≤ 60 ° C) ama dib-u-dhaqidda (cadaadis ≤ 0.3MPa) si aad uga saarto wasakhda qoto dheer.

(2) Shuruudaha qalajinta: Ka dib markaad nadiifiso, isticmaal hawo cadaadis leh oo aan saliid lahayn si aad u qallajiso (si looga fogaado oksaydheynta ay keento wasakhda biyaha ee hartay).

(3) Taboo: Ha ku qoynin asiidhyo xooggan (sida asiidhka hydrochloric) ama saldhigyo xooggan (sida sodium hydroxide) si looga fogaado inay waxyeello u geystaan ​​​​lakabka passivation ee dusha sare.

S2: Shaandhadani ma ku habboon tahay saliidaha viscosity-ga sareeya sida saliidda geerka iyo asfalt-ka?

A2: Hirgelinta: Waxay taageertaa dareerayaasha shaandhaynta leh isku-dhafnaan firfircoon ≤ 680 cSt (centics) (sida saliidda gear-ka ISO VG 680), maadaama qaab-dhismeedka shabagga lakabka badan leh uu u adkeysan karo kala duwanaanshaha cadaadiska ≤ 0.15 MPa.

Xadka heerkulka: Hubi in heerkulka saliidda uu yahay ≤ 300 ° C (ugu sarreeya muddada gaaban oo ah 400 ° C) si looga fogaado daalka birta ee ka dhasha heerkulka sare.

Kiiska Dhacdada: Waxaa si weyn loogu isticmaalay shaandhaynta saliidda haydarooliga iyo nidaamyada gudbinta asfalt ee mashiinnada macdanta.

S3: Saxnaanta magacaaban ee shayga shaandhaynta ma la jaanqaadaysaa saamaynta shaandhaynta dhabta ah?

A3: Qeexitaanka saxnaanta: Saxnaanta magacaaban waxay ku salaysan tahay tijaabada qiimaha beta (ISO 16889), tusaale ahaan, β ₅=200 waxay muujinaysaa hufnaanta dhexda ee ≥ 99.5% walxaha ≥ 5 microns.

Arrimaha Saameynaya: Waxtarka dhabta ah wuxuu yeelan karaa leexasho dhan ± 5% sababtoo ah nadaafadda dareeraha, heerka socodka (lagu taliyay 1-3 m/s), iyo isbeddelka heerkulka.

Habka Xaqiijinta: Cabbiraadda iyo habaynta goobta waxaa lagu samayn karaa iyadoo la adeegsanayo miis-xakameyn walxaha ah (oo waafaqsan heerka ISO 4406).

sifooyinka

Iska caabbinta daxalka: Birta aan miridhku lahayn ee 304 waxay ka kooban tahay 18% chromium iyo 8% nickel, saamigan daawaha ah wuxuu siinayaa iska caabin aad u fiican oo daxalka ah. Hadday tahay jawi qoyan, aashito, ama xaalado alkaline ah, birta aan miridhku lahayn ee 304 waxay ilaalin kartaa xaalad dusha sare oo wanaagsan mana aha mid si fudud u miridhku u daxalayso ama u milantay.

Xoogga farsamada iyo adkeysiga: Birta aan miridhku lahayn ee 304 waxay leedahay xoog iyo adkaysi wanaagsan, waxayna u adkeysan kartaa cadaadis sare iyada oo aan lahayn qaab-dhismeed ama jab. Tani waxay u suurtagelinaysaa shaandhada saliidda birta aan miridhku lahayn ee 304 inay ilaaliso waxqabadka shaandhaynta deggan xaaladaha cadaadiska sare.

Saxnaanta sifeynta la hagaajin karo: Shaandheeyayaasha saliidda ee birta aan miridhku lahayn ee 304 badanaa waxay leeyihiin cabbirro daloolo oo kala duwan oo laga dooran karo, qeexitaannada ku habboonna waxaa lagu dooran karaa iyadoo loo eegayo baahiyaha shaandhaynta gaarka ah si loo daboolo shuruudaha shaandhaynta ee dareerayaasha ama gaasaska kala duwan.

Si ballaaran ayaa loo dabaqi karaa: Shaandhada saliidda ee birta aan lahayn ee 304 waxay ku habboon tahay shaandhaynta dareerayaasha iyo gaasaska kala duwan, gaar ahaan si fiican ayay uga shaqeysaa warshadaha sida batroolka, kiimikada, iyo daawooyinka. Iska caabbinta daxalka iyo xooggeeda sare waxay u suurtagelinaysaa inay ilaaliso hufnaanta shaandhaynta sare xitaa deegaannada adag.
