Bacaha shaandhada siigada waa qalabka ilaalinta deegaanka ee si weyn loogu isticmaalo wax soo saarka warshadaha. Inta badan waxaa loo isticmaalaa in lagu qabto oo lagu sifeeyo boodhka{1}}gaas ka kooban si loo ilaaliyo deegaanka iyo caafimaadka dadka. Heerarka wax soo saarka iyo tijaabinta ee bacaha shaandhada boodhka ayaa muhiim u ah tayada.
Kuwa soo socda ayaa ah heerarka wax soo saarka iyo tijaabinta ee bacaha shaandhada boodhka:
1. Heerarka habka wax-soo-saarka waa sida soo socota
Qalab tayo sare leh oo fibre -, sida PPS, PTFE, NMO, iwm., waa in la doortaa, kuwaas oo u adkaysta heerkulka sare, daxalka, iyo antistatic.
Habka tolida loo isticmaalo, sida calending dusha iyo calending, ka dhigaysa bacda shaandhaysa boodhka ay leeyihiin permeability hawada aad u fiican iyo saamaynta nadiifinta boodhka.
Farsamaynta farsamaynta macquulka ah, sida goynta, tolida, dhalaalka kulul, iwm, waxay hubisaa in qaab dhismeedka bacda shaandhada boodhka ay tahay mid deggan oo aan fududayn in la jebiyo.
Nidaamka xakamaynta tayada adag, si adag u xakameynaya soo iibsiga alaabta ceeriin, habka wax soo saarka, kormeerka alaabta la dhammeeyey iyo xiriirinta kale si loo hubiyo tayada bacaha shaandhada boodhka.
Daawaynta dusha wanaagsan, sida heesaha, dejinta kulaylka, daahan PTFE, iwm., waxay wanaajisaa iska caabbinta xidhashada iyo ka-hortagga- dhexgalka bacaha shaandhada boodhka.
2. Heerarka kormeerka
Kormeerka muuqaalka: Hubi in dusha bacda shaandhada boodhka ay leedahay cillado sida burbur, wasakh, dalool, iyo midab labis ah.
Kormeerka jirka: sida cabbirka, miisaanka, dhumucda, xajinta hawada iyo tilmaamayaasha kale si loo hubiyo in bacda shaandhada boodhka ay buuxiso shuruudaha naqshadaynta.
Kormeerka makaanikada: sida xoogga, dhererka, xoogga jebinta iyo tilmaamayaasha kale si loo qiimeeyo nolosha adeegga iyo xoogga xajinta ee bacda shaandhada boodhka.
Kormeerka iska caabinta daxalka: Iyada oo loo marayo tijaabada buufinta milixda, aashitada iyo alkali immersion iyo habab kale, caabbinta daxalka ee bacda shaandhaynta boodhka ee deegaanno kala duwan ayaa la tijaabiyaa.
Kormeerka hufnaanta sifaynta: Iyada oo loo marayo habka miisaanka go'an, habka oscillation ee wakhtiga iyo habab kale, hufnaanta sifaynta bacda shaandhaynta boodhka ee boodhka-gaaska ka kooban ayaa la tijaabiyaa.
Nadiifi{0}kormeerka kormeerka: Iyada oo loo marayo tijaabada saxanka qaybinta socodka hawada, cabirka cadaadiska cadaadiska iyo habab kale, bacda shaandhada boodhka waxaa lagu qiimeeyaa saameenteeda nadiifka ah{1}.
Kormeerka caabbinta heerkulka: Iyada oo loo marayo foornada heerkulka joogtada ah, foornada heerkulka sare iyo qalabka kale, bacda shaandhada boodhka waxaa lagu tijaabiyaa dulqaadkeeda heerkul kala duwan.
Kormeerka badbaadada: Hubi in bacda shaandhada boodhka ay si adag u tolan tahay si looga hortago daadinta siigada iyo wasakhowga deegaanka ee ay keento burbur.
