Foorno bir ah oo midab guri leh
Fikradda
Laga bilaabo dhammaystirka warshaddii ugu dambeysay ee birta kulul ee ka soo baxda qaboojinta qulqulka laminar ilaa heerkulka la dejiyay, kaas oo ka kooban gariiradda dabaysha, gariiradda birta ka dib qaboojinta, iyadoo loo eegayo baahiyaha kala duwan ee isticmaalayaasha, oo leh khad dhammaystiran oo kala duwan (fidsan, toosin, jarid isdhaafsan ama dherer leh, kormeer, miisaan, baakad iyo astaan, iwm.) oo noqda saxan bir ah, duub fidsan iyo alaabada jarista dhererka leh ee birta.
Qalabka Q235B, Q345B, SPHC, 510L, Q345A, Q345E
Waxay ku habboon tahay dhismayaasha warshadaha iyo kuwa madaniga ah, bakhaarrada, dhismayaasha gaarka ah, saqafka guriga ee qaab dhismeedka birta ah ee ballaaran, qurxinta derbiga iyo gudaha iyo dibadda, oo leh miisaan fudud, xoog sare, midab qani ah, dhisme ku habboon, dhulgariir, dab, roob, cimri dheer, dayactir la'aan iyo astaamo kale, si ballaaran ayaa loo dhiirrigeliyay loona dabaqay.
Birta midabaysan ee gariiradda ah waa nooc ka mid ah walxaha isku dhafan, oo sidoo kale loo yaqaan saxan bir ah oo midabaysan oo laga sameeyay bir xarig ah oo ku jirta khadka wax soo saarka ka dib marka si joogto ah loo nadiifiyo dusha sare, loo isticmaalo phosphating iyo daaweynta kale ee dahaarka wareejinta kiimikada, oo lagu dahaadhay dahaarka dabiiciga ah ee alaabada dubista.
Gariiradda midabku waa nooc ka mid ah walxaha isku dhafan, labadaba saxan bir ah iyo walxo dabiici ah. Ma aha oo kaliya xoogga farsamada ee saxanka birta iyo waxqabadka qaabaynta fudud, laakiin sidoo kale agabka qurxinta dabiiciga ah ee wanaagsan, iska caabbinta daxalka.
Noocyada dahaarka isku-xidhka midabka waxaa loo qaybin karaa: polyester (PE), silicon modified polyester (SMP), polyvinylidene fluoride (PVDF), polyester-ka iska caabbinta cimilada sare (HDP), iyo clinker sol.
Qalabka birta midabka leh waxaa loo qaybiyaa shan qaybood: baakadaha, qalabka guriga, qalabka dhismaha, qalabka indhaha iyo agabka qurxinta. Kuwaas waxaa ka mid ah, tignoolajiyada qalabka guriga ee midabka leh ee birta ah ayaa ah shuruudaha ugu fiican uguna wanaagsan, uguna sarreeya ee wax soo saarka.
Warshadaha Kale
Adeegsiyada kale ee warshadaha waa qaybaha baaskiillada, tuubooyinka kala duwan ee la alxamay, armaajooyinka korontada, ilaalada waddooyinka waaweyn, khaanadaha dukaamada waaweyn, khaanadaha bakhaarka, deyrarka, dahaarka kuleyliyaha biyaha, sameynta foosto, jaranjarada birta ah iyo qaybaha shaambadaynta ee qaabab kala duwan leh. Iyadoo horumarka joogtada ah ee dhaqaalaha, habaynta eber ee warshadaha oo dhan, horumarka degdegga ah ee warshadaha wax lagu farsameeyo oo boqoshaadaya, baahida saxanka aad ayuu u kordhay, laakiin sidoo kale wuxuu kordhiyay baahida suurtagalka ah ee saxanka la shiiday ee kulul.
Foornada ka hortagga daxalka waa qalabka dhismaha ee loogu talagalay warshadaha kiimikada. Waa maxay faa'iidooyinka gaarka ah ee foornada ka hortagga daxalka ee warshadaha kiimikada? Aan eegno.
1) Ka hortagga daxalka:
Foornada ka hortagga daxalka ma aha mid fudud in la noqdo daxalka aashitada iyo alkali, si ka duwan foornada birta iyo agabka kale oo keliya lakabka dibadda si loo sameeyo farsamaynta, laakiin waxay ka timid dabeecadda daxalka kiimikada. Iska caabbinta daxalka ee aadka u fiican waa doorashada ugu fiican ee agabka saqafka kiimikada ee warshadaha.
2) Xoog iyo adkaysi:
Iska caabbinta saameynta, iska caabbinta jiidista, ma fududa in la jabiyo. Haddii ay jirto masaafada taageerada 660mm, culayska rarista waa 150kg. Foornooyinka ma dillaacaan oo ma dhaawacmaan.
3) Iska caabbinta cimilada:
Iyada oo ay ugu wacan tahay ku darista walaxda ka hortagga UV-ga ee agabka, waxay runtii ciyaari kartaa shucaac ka hortagga UV-ga. Waxay xallisaa dhibaatada iska caabbinta cimilada ee balaastikada caadiga ah, cimriga adeegga ee taaylada ka hortagga miridhku waa 3 jeer ka badan badeecadaha birta caadiga ah.
4) Buuqa hoose:
Marka roob da'o, buuqu wuxuu ka badan yahay 30dB marka loo eego muraayadaha saqafka birta ah oo ay ku jiraan foornada birta midabka leh. Haddii roob da'o ama cimilo xun timaado, buuqa iyo saameynta ayaa la yareyn karaa.
5) Daxal la'aan:
Foornada ka hortagga daxalka lafteedu ma miridho, midabkeeduna waa mid dhalaalaya oo qurux badan. Waxay ka hortagtaa dhibaatada wasakhda miridhku keeno oo ay keento daxalka.
