PE-da bannaanka ah ee tuubo caag ah oo dahaarka leh
PE ka baxsan tuubo caag ah oo dahaarka leh, Dahaarka (duubay) caag isku dhafan tuubo bir ah oo aan xaddidnayn dhexroorka, dhumucda lakabka dahaarka ayaa sidoo kale si aan kala sooc lahayn loo dooran karaa, marka loo eego xaaladaha dhexdhexaadka ah ee daxalka, dooro dhumucda dahaarka kala duwan, dhererka sidoo kale wuxuu gaari karaa 6-12 mitir;Dhexroorka isku midka ah ee isku midka ah, dahaarka (duuban) caag ka samaysan tuubo bir ah ayaa guud ahaan u dhexeeya 0.5-1mm, dusha tuubada siman, ma aha oo kaliya isku-dheelitirnaanta khilaafku waa mid yar, iyo isku-dhafka is-qabsiga sidoo kale waa yar yahay, luminta dareeraha tuubada waa yar tahay. socodka gudbintu waa weyn yahay, si loo gaaro badbaadinta tamarta.Sanadihii la soo dhaafay, tuubooyinka birta spiral anti-daxalka ayaa si weyn loo isticmaalaa in dhismaha biyaha iyo dheecaanka, cabitaanka biyaha qaybinta tuubooyinka injineernimada, kantaroolka dabka, ee tuubooyinka birta ugu badan dab daxalka ka hor inta aan la isticmaalin kulul maquufin bir galvanized, bulshada badan, hotels, dhismayaasha xafiisyada ayaa hadda isticmaalaya epoxy budada birta ka hortagtaa oo leh labada dhinac caag dahaarka ah waxaa laga codsadaa in gudaha iyo dibaddaba sida walxaha tuubada dabka, muuqaalkeeda qurux badan oo waara, Waxay noqotay wax soo saarka ugu weyn ee warshadaha soo baxaya qarniga 21aad.PE gudaha EP dahaarka caag tube bir xirfadle iibka budo dahaarka tube bir caag ku daray olol retardant iyo epoxy resin budada modified, iska caabin heerkulka daahan waa ka sarreeya, in isticmaalka muddada-dheer ma guban, ha jilcin.
Dibedda Beebka Caaga ah ee Dahaarka leh ee Pe Composite, Faa'iidooyinka
Filimka rinjiga ah ee budada epoxy tube birta lidka ku ah waa mid adag, biyaha u adkaysta oo aan sun ahayn.Xabag adag, dhejis wanaagsan oo u dhexeeya filimka rinjiga iyo filimka rinjiga.Iska caabin heer sare ah oo ka hortagga miridhku iyo biyaha, isticmaalka alaabada cayriin ee heer sare ah ee ka hortagga miridhku, si loo hubiyo waxqabadkeeda ka hortagga miridhku.Waxay leedahay awood farsamo oo wanaagsan, filim adag, caabbinta naaxinta iyo iska caabinta saameynta.Mawduuc adag oo sarreeya, filim qaro weyn.Qaab dhismeedka kelli ee budada epoxy birta anticorrosive waxaa lagu gartaa kooxaha epoxy firfircoon ee silsiladda kelli, kaas oo ku yaalaan karaa dhamaadka, qaab dhismeedka dhexe ama giraanta silsilad kelli.
Sababtoo ah kooxaha epoxy-ga firfircoon ee qaab-dhismeedka molecular, waxay la xiriiri karaan noocyo kala duwan oo ah wakiilka daaweynta si ay u sameeyaan polymers aan la milmi karin oo aan la dafiri karin oo leh qaab-dhismeedka shabakad saddex-gees ah.Dahaarka budada Thermosetting waxaa inta badan loo isticmaalaa dalal kala duwan: epoxy-polyester daahan budo ah, epoxy phenolic daahan budada ah, daahan budada polyester, epoxy-polyester daahan.iyaga ka mid ah, daahan budada epoxy waa kala duwan ee hore ee codsiga, sidoo kale waa wax soo saarka hadda ee daahan budo caag ah, oo si ballaaran loo isticmaalo geeddi-socodka buufinta electrostatic, in daahan madaxtooyada ka ciyaara meel aad u muhiim ah;Sababtoo ah caabbinta daxalka kiimikada sare, daahan budada epoxy phenolic waxaa inta badan loo isticmaalaa daahan ka hortagga daxalka.
Dahaarka budada ah ee Thermoplastic ayaa u badan
Dahaarka budada polyetylen, dahaarka budada POLYvinyl chloride, daahan budada polypropylene, daahan budada chlorinated polyether, daahan budada naylon, polyphenylene sulfide daahan budada ah, iwm, kuwaas oo daahan budo thermoplastic leeyihiin faa'iidooyin iyo faa'iido darrooyinka.Balaastikada heerkulbeegga ah waxay leeyihiin heer-ku-daweyn ka wanaagsan iyo qoynta sababtoo ah miisaankooda kelliga ah ee yaryar, taas oo ka dhigaysa inay ku dhegganaadaan jirka tuubada marka ay dahaaran yihiin tuubada birta, waxayna ka dhigi kartaa tuubada birta dahaarka leh inay hesho dusha filim caag ah oo siman.Balaastikada heerkulbeegga ee sida caadiga ah loo isticmaalo waa: resin epoxy, resin phenolic, resin amino iyo wixii la mid ah.Dhumucdiisuna waxay u dhaxaysaa 100 micron iyo 500 microns, badiyaa 350 microns.
PE ka baxsan tuubo caag ah oo dahaarka leh, 1. Caafimaadka, aan sunta ahayn, qolof lahayn, taranta noolaha, hubi tayada dareeraha 2. 3. Habka rakibaadda waa qaan, ku habboon oo degdeg ah, iyo xidhiidhka la leh tuubada galvanized caadiga ah waa isku mid.4. Iska caabin cimilada wanaagsan.5. Darbiga tuubada siman, hagaajinta hufnaanta gudbinta, nolosha adeeg dheer.
Meesha ka baxsan PE-da isku-dhafka ah ee tuubada balaastiigga ah ee dahaarka leh, Habka isku xirka:isku xirka dunta: isticmaal silig qalloocan ama mashiinka gacanta silig koronto si aad u farsamayso dunta tuubada, fiiro gaar ah u yeelo qaboojinta inta lagu jiro hawsha;Isku xirka flange, cabbiraadda goobta, sawirida khariidad farsamaynta khad qudha, dahaarka farsamaynta, dahaarka caagga ah, ka dibna loo raro rakibaadda goobta;Tuubooyinka birta ah ee aan dahaarka lahayn, ee balaastigga ah iyo qalabka tuubooyinka ayaa loo isticmaali karaa gudaha garoonka, alxanka flange, isku xirka dhuumaha, ka dibna la kala diro si loogu dhejiyo, farsamaynta balaastiigga, ka dibna loo qaado goobta rakibidda;Qalabka tuubooyinka caagga ah ee dahaarka leh ee la dhammeeyey waa in la door bidaa;Godadka waa in lagu cadaadiyaa mashiinka duubista, iyo jeexjeexyada waa in ay noqdaan kuwo waafaqsan heerarka ku habboon.
