Waa maxay sababta aan u doorano valves PVDF, qalabyada tuubooyinka iyo tuubooyinka?
Waa maxay sababta aan u doorano valves PVDF, qalabyada tuubooyinka iyo tuubooyinka?
Waxaa jira UPVC, CPVC, PPH, PVDF, FRPP valves, qalabyada tuubooyinka iyo tuubooyinka suuqa. Waa maxay sababta aan u doorano alaabta PVDF? Marka hore waa inaan ogaanaa sifada PVDF ee soo socota:
Waa maxay Sifada Maaddada PVDF?
Polyvinylidene fluoride, oo loo yaqaan PVDF, waa monomer ay sameeyeen trifluoroethylene, hydrofluoric acid iyo budada zinc, iyo ka dib polymerization si loo dhaliyo crystalline cad oo adag.
Alxanka dabada kulul ka dib, xiriiriyaha waa in lagu hagaajiyaa mashiinka alxanka dabada dhalaalaysa kulul, iyo qaboojinta xiriiriyaha sida waafaqsan xilliga qaboojinta kaas oo ku qeexan xeerarka ilaalinta cadaadiska iyo qaboojinta ee kululaynta dabada mishiinka alxanka. qaboojinta ka dib, cadaadiska eber ka dhig, ka dibna ka saar tuubada alxanka leh.

1.Cabsiga heerkulka:
Nidaamka tuubada PVDF wuxuu leeyahay xasillooni heerkuleed oo wanaagsan, wuxuu ilaalin karaa waxqabadka xasilloon ee heerkul kala duwan, isticmaalka muddada dheer ee heerkulka ugu sarreeya ilaa 150 ° C ama wax ka badan.
2.Awoodda makaanikada:
Marka la barbardhigo alaabada kale ee caaga ah, PVDF-ga, tuubooyinka tuubooyinka iyo tuubooyinka waxay leeyihiin awood adag oo adag, iska caabin saameyn leh iyo caabbinta xajinta, waxayna ilaalin kartaa adagaanta iyo adkaanta wanaagsan xitaa heerkulka hooseeya.
3.Deganaanshaha cabbirka:
Dooxooyinka PVDF, xirmooyinka tuubooyinka iyo tuubooyinka waxay muujinayaan iskudhaf yar oo balaadhinta kulaylka marka kulaylka ama qabowgu hoos u dhaco, si ay u ilaaliso saxnaanta cabbirka deggan.
4. Adag iyo qallafsanaan:
qallafsanaanta sare iyo qallafsanaanta wanaagsan, samaynta tuubada ma fududa in la qaabeeyo oo si sahlan loo rakibo.
Waa maxay sifooyinka kiimikada PVDF?
1. Caabbinta daxalka kiimikada:
Dooxooyinka PVDF, xirmooyinka tuubooyinka iyo tuubooyinka waxay leeyihiin qallafsanaan kimikal sare leh inta badan asiidhka, alkalis, cusbada iyo dareerayaasha organic badan, taas oo ah walxaha ugu fiican ee gudbinta warbaahinta daxalka ah ee warshadaha kiimikada.
2.Adhejin la'aan:
oogada siman, ma fududa in loo hoggaansamo maaddada, taas oo yarayn karta isu-ururinta miisaanka iyo ifafaale xidhidhidda habka gudbinta.
Waa maxay habka isku xidhka alaabta PVDF?
Si la mid ah PPH, nidaamka dhuumaha PVDF waxaa ku xiran dhalaal kulul sidoo kale, kaas oo sidoo kale loo qaybin karo alxanka dhalaalka kulul iyo alxanka dhalaalka kulul. Tallaabooyinka gaarka ah ee alxanka dhalaalka kulul ee la mid ah kan PPH sidoo kale.
Tallaabooyinka gaarka ah ee alxanka dhalaalka kulul ee PVDF la mid ah sidoo kale PPH, laakiin waxaa jira qaar ka duwan tixraaca habka, faahfaahinta sida hoos ku qoran:

Waa kuwee warshadaha codsiyada PVDF valves, xirmooyinka tuubooyinka iyo tuubooyinka?
1. Warshadaha Kiimikada:
Si ballaaran loo isticmaalo hababka kala duwan ee kiimikooyinka nidaamka bixinta dareeraha, sida qaadista aashitada, xalalka alkali, oxidants, dareerayaasha iyo walxaha kale ee daxalka.
2. Semiconductor iyo warshadaha elektiroonigga ah:
Deegaanka qolka nadiifka ah ee nidaamka bixinta biyaha ultrapure, iyo sidoo kale kaydinta kiimikada iyo nidaamka qaybinta sida alaabta tuubooyinka ee doorbidaya.
3. injineernimada ilaalinta deegaanka:
Dooxooyinka PVDF, xirmooyinka tuubooyinka iyo tuubooyinka ayaa si weyn loogu isticmaalaa caabbinta daxalka iyo ku habboonaanta noolaha ee daaweynta biyaha wasakhda ah, nadiifinta biyaha badda, iyo daawaynta ka hor iyo marxaladaha daawaynta ka dib ee hababka xuubka osmosis-ka.
4. Farmashiyaha iyo tignoolajiyada bayoloji:
In geeddi-socodka wax soo saarka u baahan yahay in si adag loo xakameeyo wasakhowga iyo ka hortagga dhacdooyinka taranta microbial, dhuumaha PVDF sababta oo ah nadaafadda sare, aan sun iyo ur la'aan waxaana loo isticmaalaa gudbinta biyo saafi ah, dhexda dawooyinka ama dareerayaasha kale.
5. Tamarta iyo warshadaha nukliyeerka:
Sababtoo ah iska caabbinta shucaaca iyo iska caabinta heerkulka sare, waxaa sidoo kale loo isticmaalaa nidaamka qaboojinta biyaha ee qaar ka mid ah dhirta tamarta nukliyeerka iyo tas-hiilaadka kale ee tamarta.
Marka la soo koobo, tuubooyinka fluoride ee polyvinylidene waxay noqdeen doorashada ugu fiican ee tuubooyin badan oo heer sare ah oo qallafsan sababtoo ah caabbinta kiimikaad ee heer sare ah, xoog sare, iska caabin heerkul aad u fiican iyo sifooyin koronto oo wanaagsan.
