Habka Connection ee tuubada dabka: dun, jeexdin, flange, iwm The epoxy gudaha iyo dibadda tuubada birta ka kooban ee ilaalinta dabka waa wax ka beddelka-waajib culus anti-daxalka budada epoxy, kaas oo uu leeyahay iska caabin kiimikada aad u fiican.Waxay asal ahaan xallisaa dhibaatooyin badan sida daxalka dusha sare ee miridhku iyo maqaarka gudaha ee gidaarka gudaha alaabada la midka ah ka dib isticmaalka muddada dheer, si looga fogaado xannibaadda gudaha ee saameeya isticmaalka, si ay si weyn u wanaajiso nolosha adeegga ee tuubooyinka dab-damiska ee gaarka ah.Sababtoo ah ku darida walxaha ololka ee alaabta daahan, caabbinta heerkulka alaabta ayaa la wanaajiyey marka la barbar dhigo alaabta kale ee la midka ah.Sidaa darteed, ma saameyn doonto isticmaalka marka heerkulka deegaanku si xoog leh u kaco.Nolosha adeegga iyo waxqabadka tuubooyinka dabka ee gudaha iyo dibaddaba waxay aad uga fiican yihiin kuwa tuubooyinka galvanized.Midabku waa casaan.

Warshadeenu waxay ku takhasustay soo saarista tuubooyinka dabka, tuubada birta galvanized, tuubada daahan budada, tuubada daahan budada ah iyo tuubada birta 6-inch.Codsiga: Biyaha dabka, sahayda gaaska iyo nidaamka dhuumaha gaadiidka dhexdhexaadka ah ee xumbo.Tayada alaabadu waxay dhaaftaa kastamka waxayna ku gudubtaa imtixaano badan ka hor inta aanad ka tagin warshadda.U hoggaansamaan heerarka tayada qaranka iyo kuwa caalamiga ah.

(1) Qalabka farsamada sare.Xabagta Epoxy waxa ay leedahay isku xirnaan xooggan iyo qaab dhismeed unugyo cufan, sidaa awgeed astaamihiisa farsamaysan ayaa ka sarreeya resins-ku-dhejinta guud sida resin phenolic iyo polyester aan saturated lahayn.

(2) Dahaarka tuubada dabka ee dahaarka leh waxay qabataa resin epoxy, kaas oo leh dhejis adag.Nidaamka daawaynta resin Epoxy ka kooban epoxy group, hydroxyl group, ether bond, amine bond, ester bond iyo kooxaha kale ee polar oo leh firfircooni weyn, kaas oo siinaya epoxy la daaweeyay adhesion aad u fiican in birta, ceramics, galaas, shuban, alwaax iyo substrates kale.

(3) Yaraynta daawaynta yar.Guud ahaan 1% ~ 2%.Waa mid ka mid ah noocyada ugu yar ee daawaynta ugu yar oo ka mid ah resins heerkulbeegga (resin phenolic waa 8% ~ 10%; xabagta polyester-ka aan saturated waa 4% ~ 6%; xabagta silikoon waa 4% ~ 8%).Iskuxidhka fidinta tooska ah sidoo kale waa mid aad u yar, guud ahaan 6 × 10-5/℃. Sidaa darteed, mugga ayaa isbedelaya wax yar ka dib daaweynta.

(4) Shaqo wanaag.Xabagta Epoxy asal ahaan ma soo saarto kacsanaanta unugyadu hooseeyaan inta lagu jiro daawaynta, sidaa darteed waxa lagu samayn karaa cadaadis hoose ama cadaadiska xidhiidhka.Waxay la shaqayn kartaa wakiilada daaweynta kala duwan si ay u soo saaraan dahaarka deegaanka u fiican sida dareere-free, adag adag, daahan budada ah iyo daahan biyaha ku salaysan.

(5) Dabool koronto oo heersare ah.Xabagta Epoxy waa resin heerkulbeeye leh sifooyin antistatic wanaagsan.

(6) Degenaansho wanaagsan iyo iska caabin kiimiko oo aad u wanaagsan.Xabada Epoxy oo aan lahayn alkali, milix iyo wasakh kale ma fududa in ay xumaato.Ilaa iyo inta si habboon loo kaydiyo (shaabadaysan, xor ka ah qoyaanka iyo heerkulka sare), muddada kaydinta waa 1 sano.Ka dib taariikhda dhicitaanka, haddii kormeerku u qalmo, weli waa la isticmaali karaa.Xarunta daweynta Epoxy waxay leedahay xasilooni kiimikaad oo heer sare ah.Iska caabbinta daxalka ee alkali, acid, milixda iyo warbaahinta kale way ka fiican tahay tan xabagta polyesterka aan saturated lahayn, resin phenolic iyo resins kale oo heerkulbeeg ah.Sidaa darteed, xabagta epoxy-ga ayaa si weyn loogu isticmaalaa sidii hore ee ka hortagga daxalka.Sababtoo ah xabagta epoxy ee la daweeyay waxay leedahay qaab-dhismeedka shabakad saddex-geesood ah waxayna iska caabin kartaa impregnation ee saliidda, waxaa si weyn loo isticmaalaa in dahaarka gudaha gidaarka ee haamaha saliidda, kuwa saliidda iyo diyaaradaha.

(7) caabbinta kulaylka ee xarunta daweynta epoxy guud ahaan waa 80 ~ 100 ℃.Noocyada kulaylka u adkaysta ee resin epoxy waxay gaari karaan 200 ℃ ama ka sareeya.
