Waa maxay sababta u dooratid tuubada PTFE ee jilicsan ee wareejinta kiimiko heer-sare ah?

Warshadaha wax ka qabta dareerayaasha gardarrada ah, doorashada tuubada saxda ah waxay muhiim u tahay hubinta badbaadada iyo waxtarka labadaba. Marka la wareejinayo asiidhyada kulul, saldhigyada, ama dareerayaasha organic, injineeradu inta badan waxay la kulmaan hal caqabad oo adag: sida loo hubiyo waxqabadka xasilloon ee heerkulka aadka u daran iyo xaaladaha daxalka. Tani waa meeshaTuubbo siman oo PTFE ahnoqday xalka la door bidayo.

Maqaalkan, waxaan ku baari doonaa sababta Smooth Bore tuubooyinka PTFE ay uga sarreeyaan fursadaha kale ee wareejinta kiimikada heerkulka sare, diiradda saaraya caabbinta kiimikada, xasilloonida kuleylka, iyo faa'iidooyinka badbaadada.

Caqabadda Wareejinta Kiimikada Heerkulka Sare

Dheecaannada Gardarada ah ee ku jira Xaalado Adag

Dhirta kiimikooyinka, wershadaha, iyo shaybaadhka ayaa inta badan gacanta ku haya dareerayaasha sida sulfuric acid, sodium hydroxide, ethanol, ama acetone. Warbahintani maaha oo kaliya mid aad u daxalaysa laakiin sidoo kale inta badan lagu wareejiyo heerkul sare. Tuubooyinka caagga ah ama caag ah ayaa ku dhibtooday xaaladahan oo kale, oo ay qabaan:

- Burburka ama bararka marka ay la kulmaan asiidhyada iyo dareerayaasha

- dildilaaca ama adkaanta heerkulka sare

- Ku shubista wasakhda dareere xasaasi ah

Injineerada, cabsida ayaa ah in tuubada uu ku guuldareysto inta lagu jiro hawlgalka, taasoo keenaysa daadinta, wax soo saarka hoos u dhaca, ama xataa khataro badbaado..

Waa maxay sababta tuubada PTFE ee jilicsan u taagan tahay

Si ka duwan tuubooyinka caadiga ah, PTFE (Polytetrafluoroethylene) waxay bixisaa isku-dar gaar ah oo aan falcelin lahayn iyo iska caabin kulaylka. Naqshaddeeda jilicsan waxay sidoo kale yaraynaysaa qulqulka iyo ururinta dareeraha, taasoo ka dhigaysa mid aad loogu kalsoonaan karo codsiyada tuubooyinka kiimikada heerkulka sare.

Faa'iidooyinka muhiimka ah eeTuubbo siman oo PTFE ah

1. Caabbinta Kiimikada Gaarka ah

Mid ka mid ah sababaha ugu muhiimsan ee loo doorto tuubada PTFE ee iska caabbinta kiimikada waa awoodda ay u leedahay in ay u adkeysato ku dhawaad ​​dhammaan walxaha daxalka. PTFE waa mid aan firfircoonayn inta badan asiidhyada, alkalisyada, iyo dareerayaasha, hubinta waarta muddada dheer iyada oo aan hoos u dhicin.

- Asiidhyada: Laga soo bilaabo hydrochloric acid ilaa sulfuric acid, PTFE wali wax saamayn ah kuma yeelan.

- Saldhigyada: Caustic soodhaha ama potassium hydroxide ma wiiqaan darbiyada PTFE.

- Xalalka dabiiciga ah: U adkaysta khamriga, ketones, iyo hydrocarbons.

Marka la barbardhigo caag ama tuubooyinka PVC, waafaqid kiimikaad sare ee PTFE waxay meesha ka saaraysaa welwelka ku saabsan weerarka kiimikada, qallafsanaanta, ama burburka walxaha.

2. Deganaanshaha Heerkulka Sare

Tuubada PTFE ee jilicsans waxaa loogu talagalay in ay si la isku halleyn karo ugu shaqeeyaan heerkul aad u daran, sida caadiga ah laga bilaabo -70°C ilaa +260°C (-94°F ilaa +500°F). Awooddani waxay ka dhigaysaa inay ku habboon yihiin wareejinta kiimikaad heerkulka sare leh, halkaasoo tuubooyinka kale ay jilciyaan, beddelaan, ama dillaacaan.

Codsiyada kulaylka sarreeya ee joogtada ah: PTFE waxay ilaalisaa dabacsanaanta iyada oo aan lumin awoodda farsamada.

Baaskiilka kulaylka: Awood u leh u adkeysiga isbeddelada degdega ah ee ka imanaya kulaylka iyo qabowga iyada oo aan waxyeello kadeedku keenin.

Margin Badbaadada: Waxay yaraynaysaa khatarta ah in tuubada degdega ah ay xumaato marka la qabanayo warbaahinta kiimikada ee kulul.

3. Naqshad jilicsan oo dhalaalaysa oo loogu talagalay socodka nadiifka ah

Si ka duwan tuubooyinka isku dhafka ah, tuubooyinka PTFE ee siman waxay ka muuqdaan dusha gudaha oo leh khilaaf aad u hooseeya oo aan lahayn godad ay dareeruhu ku urursan karaan. Naqshadani waxay bixisaa faa'iidooyin dhowr ah:

Hoos u dhaca cadaadiska ee wareejinta dareeraha hufan

Khatarta faddaraynta oo la yareeyey, taas oo muhiim u ah codsiyada dawada iyo heerka cuntada

Way fududahay in la nadiifiyo oo la nadiifiyo, oo muhiim u ah warshadaha u baahan heerarka nadaafadda adag

4. Xoogga Makaanikada oo leh Xoojinta Doorashooyinka

PTFE lafteedu waa xoog badan tahay laakiin waxaa lagu xoojin karaa tidcan birta ah ama lakabyo kale oo dibadda ah si loo kordhiyo caabbinta cadaadiska. Tani waxay ka dhigaysaa tuubooyinka PTFE ee Smooth Bore kuwo badan oo kala duwan oo ah codsiyada wareejinta kiimikada, laga bilaabo khadadka shaybaadhka cadaadiska hooseeya ilaa tuubooyinka warshadaha cadaadiska sarreeya.

- Tidcan birta ah: Waxay ku daraysaa adkeysiga iyo dabacsanaanta cadaadiska

- Xadhkaha ka-hortagga-static-ka: Ka-hortagga kharashka joogtada ah ee wareejinta kiimikada gubanaysa

- Jaakad ka-ilaaliye: Waxay ku ilaalisaa tuubooyinka meelaha cidhiidhiga ah ama bannaanka

Codsiyada caadiga ah ee tuubada PTFE ee jilicsan

Tuubooyinka PTFE ee jilicsan ayaa si weyn looga qaataa dhammaan warshadaha halkaas oo badbaadada iyo waxqabadka heerkulka sare ay muhiim u yihiin:

- Dhirta farsamaynta Kiimikada - loogu talagalay asiidhka, alkalis, iyo dareerayaasha

- Soo saarista Dawooyinka - wareejinta nadiifka ah iyo nadiifinta maaddooyinka firfircoon

- Warshadaha Saliida & Gaaska - maaraynta dareeraha gardarrada leh ee xaaladaha kulaylka sareeyo

- Soo saarista Cunnada & Cabbitaannada - wareejinta nadaafadda ee saliidaha, sharoobada, iyo walxaha dhadhanka

- Wax-soo-saarka Semiconductor - wareejin kiimiko ah oo aadka u saafi ah oo aan wasakhayn

Waa maxay sababta PTFE u tahay Maalgelinta Muddada dheer ee ugu Fiican

Halka tuubooyinka Smooth Bore PTFE laga yaabo inay lahaadaan qiime sare oo hore marka loo eego caag ama tuubooyinka heerkulbeegga, cimrigooda adeeg oo dheer, soo noqnoqoshada beddelka oo yaraatay, iyo badbaadada sare waxay ka dhigaysaa doorashada ugu kharash-oolsan mustaqbalka fog.

- Kharashaadka dayactirka oo hooseeya - beddelaad yar iyo burbur

- U hoggaansanaanta amniga oo la hagaajiyay - hoos u dhaca khatarta daadinta iyo shilalka

- Hufnaanta hawlgalka - waxqabadka xasilloon ee xaaladaha daran

Injineerada iyo maamulayaasha dhirta, doorashada tuubada PTFE ee iska caabbinta kiimikaad ma aha oo kaliya waxqabadka - waxay ku saabsan tahay ilaalinta qalabka, shaqaalaha, iyo wax soo saarka.

Gabagabo

Marka ay timaado codsiyada heerkulka sare ee tuubada kiimikada, ma jirto doorasho ka fiican oo aan ahayn Tuubada PTFE ee siman. Isku darka caabbinta kiimikada, xasiloonida kulaylka, socodka nadiifka ah, iyo cimri dhererka ayaa hubiya isku halaynta aan la isku halayn karin ee deegaanka ugu adag.

Haddi lagu maamulayo asiidhka warshad kiimikaad, dareerayaasha shaybaadhka ku jira, ama dareerayaasha kulaylka leh ee hababka warshadaha, Tuubooyinka Smooth Bore PTFE waxay bixiyaan nabada maskaxeed ee injineeradu u baahan yihiin inay si badbaado leh oo hufan u shaqeeyaan.

Maalgelinta tuubooyinka PTFE macnaheedu waa maalgelinta badbaadada muddada dheer, waxqabadka, iyo kaydinta kharashka.
