Maxaa HEPA ka samaysan tahay?

Waxaa jira noocyo badan oo agab ah oo ka kooban HEPA, kuwaas oo loo qaybin karo PP (polypropylene) warqad shaandhayn oo tayo sare leh, warqad shaandhayn PET, PP iyo PET oo ka kooban waraaqo shaandhayn tayo sare leh iyo fiber fiber galaas waraaq shaandhayn heer sare ah. Waxaa ka mid ah, PP (polypropylene) waa warqad, sidaas darteed guud ahaan lama dhaqi karo. Qayb kale oo ka mid ah shaandhada HEPA waxay ka samaysan tahay PET ama PTFE, taas oo ah asalka sheegashooyin badan oo online ah oo ku saabsan filtarrada HEPA ee la dhaqay, laakiin halkan Xiaobian waa inuu xasuusiyaa in waxtarka PET uu aad u hooseeyo.

Warqad shaandhayn oo tayo sare leh:

Waa nooc cusubShayga shaandhayntaka samaysan polypropylene by habka dhalaalidda kulul gaar ah, sheyga waa acid iyo caabbinta alkali, iska caabin daxalka, dhibic dhalaalaysa sare, waxqabadka xasilloon, non-sun, dhadhan lahayn, qaybinta lebis, la iska caabin hoose, hufnaan sare, xoog sare, ilaalinta deegaanka iyo sifooyinka kale.

Warqad shaandhaynta PET:

Waxay ka samaysan tahay suufka polyesterka iyo walxaha kale, qallafsanaanta sare, qallafsanaanta wanaagsan, caabbinta daxalka, iska caabbinta heerkulka sare, waxqabadka xasilloon, sida caadiga ah loo isticmaalo nadiifiyaha vacuum, nadiifiyaha vacuum iyo qalabka kale ee guriga oo leh shuruudaha saxda ah ee nadiifinta hoose ama mashiinnada nadiifinta ee waaweyn.

Waraaqaha shaandhada isku dhafan (PP iyo PET):

Waraaqaha shaandhada isku dhafan, oo si fudud loo dhejiyo, ayaa la dhalaaliyaa lakabka PP, ka dibna dhalaalaysa lakabka PET, si uu u dhexgeliyo barta PP iyo barta PET: si sahlan loo sameeyo, saxnaanta sifaynta ayaa la dammaanad qaadi karaa; Labadaba qallafsanaan, laakiin sidoo kale si loo hubiyo saamaynta sifaynta saxda ah ee sare.

Waraaqaha shaandhada waxtarka sare leh ee fiber-glas:

MuraayadahaFiber Filterwarqadu waa warqad shaandheyn oo dahab ah oo aad u sareysa, taas oo loo adeegsaday warshadaha nukliyeerka. Qaar ka mid ah noocyada waaweyn ee ajnabiga ah ee sifayaasha, sida Orange, IQAir, iwm., waxay ka samaysan yihiin fiilooyinka aluminium ama qolof kale oo bir ah, si loo hagaajiyo warqadda shaandhada oo si fiican u xirto si aysan u dhaawicin saameynta sifeynta.
