Dhuumaha birta caagga ah ee lagu dhejiyay tuubo bir ah oo galvanized ah iyo tuubo bir ah oo welded ayaa loo isticmaalaa sida tuubada salka.Derbiga gudaha waxa lagu dahaadhay tuubo-protein (PE)-cunto ah oo dhexroorkeedu la mid yahay tuubada galvanized ka dib marka feeraha alxanka laga saaro.Dhumucda dahaarka polyetylenka waa inuu buuxiyaa heerka HG/T 20538-2016.
Baaxadda Codsiga
(Ilaalinta deegaanka) Tiknoolajiyada birta birta ah ee la safeeyey ee birta birta ah ee caagga ah waxay dhaxashay faa'iidooyinka birta birta iyo tuubada caaga ah, iyo sida ku cad baahida suuqa, habka wax soo saarka, tallaabooyinka ka hortagga daxalka, isku xirka, kharash-ku-ool ah iyo dhinacyo kale oo badan oo macquul ah. naqshadaynta tuubada ka dib falanqayn dhamaystiran.Sidaa darteed, tuubadu waxay leedahay sifooyin farsamo oo badan, oo si ballaaran loo isticmaalo dhammaan noocyada dhismayaasha ee nidaamka sahayda biyaha qabow iyo kulul.Habka isku xirka wuxuu leeyahay isku xirka giraanta xajinta ee gaarka ah, jeexdin (clamp) isku xirka ama isku xirka xarigga xargaha, habka dhismuhu wuxuu la mid yahay isku xirka tuubada birta iyo isku xirka xadhigga siliga.
Iyada oo ay caan ku tahay wacyiga dadka ee ilaalinta deegaanka iyo caafimaadka, tubooyinka biyaha deegaanka ee cusub ayaa u soo baxa sida caleemaha bamboo roobka ka dib, waxaana jira noocyo badan oo aan la tirin karin.Dhuumaha birta ee balaastigga ah ee safan waxay dhaxlaan faa'iidooyinka birta birta iyo tuubooyinka caagga ah, laakiin waxay ka tagaan faa'iidooyinkooda.Mid ka mid ah waxyaabaha ugu muhiimsan ee naqshadeynta tuubada waa in la go'aamiyo dhumucda derbiga ee tuubada si macquul ah iyadoo loo eegayo shuruudaha iyo shuruudaha isticmaalka, iyo qiyaastani waxay si toos ah u saameyneysaa waxqabadka kharashka alaabta.Naqshadeynta dhumucda gidaarka gaarka ah ee tuubada birta safan waxaa ka mid ah dhumucda gidaarka tuubada caagga ah ee gudaha iyo dhumucda gidaarka welded ee dibadda, kaas oo go'aamiya sifooyin farsamo oo taxane ah:
1. Codsi ballaaran oo ballaadhan, qeexitaanno dhammaystiran iyo noocyo kala duwan;
2. Farsamada wax soo saarka gaarka ah;
3. Habka isku xirka la isku halleyn karo oo degdeg ah;
4. ka hortagga daxalka dusha sare wuxuu cabbiraa qumman, qurux badan;
5. Naqshadeynta dhumucda gidaarka tuubooyinka dibadda ee welded waa macquul;
6. Dhumucda derbiga ee tuubada caagga ah ee gudaha waa macquul si loo hubiyo dhexroorka;
7. badbaadinta tamarta iyo ilaalinta deegaanka, awood horumarineed oo weyn;
Dhuumaha birta dahaarka leh ee caagga ah, sidoo kale loo yaqaano tuubo dahaarka caag ah, bir-caag tuubo isku dhafan, tuubo bir ah oo isku dhafan oo caag ah, waa tuubo bir ah sida matrixka, iyada oo loo marayo buufinta, rogidda, quusinta, nuujinta habka tuubada birta (tuubada hoose) gudaha dusha sare ee lakabka caagga ah ee ka-hortagga balaastigga ah ama gudaha gudaha iyo dibadda ee tuubada birta isku dhafan ee balaastiga ah.Dhuumaha birta ee dahaarka leh waxay leedahay iska caabin daxalka oo aad u wanaagsan iyo iska caabin xun oo yar.Epoxy resin-dahaarka birta birta ah waxay ku habboon tahay sahayda biyaha iyo qulqulka, biyaha badda, biyaha diirran, saliidda, gaaska iyo gaadiidka kale ee warbaahinta, tuubooyinka birta ah ee daboolan ee PVC waxay ku habboon yihiin qulqulka, biyaha badda, saliidda, gaaska iyo gaadiidka kale ee warbaahinta.
Astaamaha Alaabta
Dhuumaha birta dahaarka leh waxay ka samaysan tahay PE (polyethylene la beddelay) oo loogu talagalay balaastiig kulul ama EP (resin epoxy) oo loogu talagalay alaabada daahan gudaha iyo dibedda, oo leh iska caabin daxaleed aad u fiican.Isla mar ahaantaana, dahaarka laftiisa ayaa sidoo kale leh korantada korantada oo wanaagsan, ma laha wax koronto ah.Nuugista biyaha hooseeya, xoogga farsamada sare, iskudhafka yar ee isku-dhafka, waxay gaari kartaa ujeedada isticmaalka muddada dheer.Waxa kale oo ay si wax ku ool ah uga hortagi kartaa dhaawaca xididdada dhirta iyo cadaadiska deegaanka ee ciidda.Isku xirka ku habboon iyo dayactirka fudud.
Faa'iidada Alaabta
1. La qabso deegaanka la aasay iyo qoyaanka, waxayna u adkeysan kartaa heerkulka sare iyo mid aad u hooseeya.
2. Awood xoog leh oo ka-hortagga faragelinta, haddii tuubada birta lagu dahaadhay sida gacanka fiilada, waxay si wax ku ool ah u ilaalin kartaa faragelinta dibadda.
3. Xoog cadaadis wanaagsan, cadaadiska ugu badan ilaa 6Mpa.
4. Waxqabadka dahaarka wanaagsan, sida tuubada ilaalinta siliga weligeed ma dhici doonto ifafaale daadsan.
5. Burr la'aan, gidaarka tuubada siman, oo ku habboon dhismaha wakhtiga xirashada fiilada ama fiilada.
