Kev sib txuas ntawm cov yeeb nkab hluav taws: xov, zawj, flange, thiab lwm yam. Cov yeeb nkab sab hauv thiab sab nraud epoxy puas steel yeeb nkab rau kev tiv thaiv hluav taws yog hloov kho hnyav-tiv thaiv corrosion epoxy resin hmoov, uas muaj cov tshuaj tiv thaiv zoo heev.Nws yooj yim daws tau ntau yam teeb meem xws li nto xeb xeb thiab sab hauv phab ntsa scaling ntawm cov khoom zoo sib xws tom qab siv mus ntev, kom tsis txhob muaj kev thaiv sab hauv cuam tshuam rau kev siv, txhawm rau txhim kho kev pab cuam lub neej ntawm cov kav dej tshwj xeeb tua hluav taws.Vim yog qhov sib ntxiv ntawm cov nplaim hluav taws kub nyhiab hauv cov ntaub ntawv txheej, qhov kub tsis kam ntawm cov khoom tau zoo dua piv nrog lwm cov khoom zoo sib xws.Yog li ntawd, nws yuav tsis cuam tshuam rau kev siv thaum lub ambient kub nce sharply.Kev pabcuam lub neej thiab kev ua haujlwm ntawm cov kav hluav taws kub sab hauv thiab sab nraud yog zoo dua li cov kav dej galvanized.Cov xim yog liab.

Peb lub Hoobkas tshwj xeeb hauv kev tsim cov yeeb nkab hluav taws, galvanized steel yeeb nkab, hmoov txheej yeeb nkab, hmoov txheej yeeb nkab thiab 6-nti steel yeeb nkab.Daim ntawv thov: hluav taws kub dej, khoom siv roj thiab ua npuas dej nruab nrab kev thauj mus los kav.Cov khoom zoo dhau ntawm kev lis kev cai thiab dhau ntau qhov kev xeem ua ntej tawm hauv lub hoobkas.Ua raws li lub teb chaws thiab thoob ntiaj teb cov qauv zoo.

(1) High mechanical zog.Epoxy resin muaj zog cohesion thiab ntom molecular qauv, yog li nws cov khoom siv kho tshuab siab dua li cov thermosetting resins xws li phenolic resin thiab unsaturated polyester.

(2) Cov txheej txheej ntawm cov yas coated hluav taws xob yeeb nkab siv epoxy resin, uas muaj zog adhesion.Epoxy resin curing system muaj epoxy pawg, pawg hydroxyl, ether daim ntawv cog lus, amine daim ntawv cog lus, ester daim ntawv cog lus thiab lwm pawg polar nrog kev ua haujlwm zoo, uas muab epoxy kho cov khoom zoo heev adhesion rau hlau, ceramics, iav, qhob, ntoo thiab lwm yam polar substrates.

(3) Kev kho me me shrinkage.Feem ntau 1% ~ 2%.Nws yog ib qho ntawm ntau hom nrog qhov tsawg tshaj plaws curing shrinkage ntawm thermosetting resins (phenolic resin yog 8% ~ 10%; unsaturated polyester resin yog 4% ~ 6%; silicone resin yog 4% ~ 8%).Lub linear expansion coefficient kuj yog me me, feem ntau 6 × 10-5 / ℃. Yog li ntawd, lub ntim hloov me ntsis tom qab kho.

(4) Kev ua haujlwm zoo.Epoxy resin yeej tsis tsim cov tsis tshua muaj molecular volatiles thaum kho, yog li nws tuaj yeem tsim nyob rau hauv qis qis lossis kev sib cuag.Nws tuaj yeem koom tes nrog ntau yam tshuaj tua kab mob los tsim cov txheej txheem ib puag ncig xws li hnyav-dawb, khoom siab, hmoov txheej thiab dej-raws li txheej.

(5) Cov rwb thaiv tsev hluav taws xob zoo heev.Epoxy resin yog ib qho thermosetting resin nrog zoo antistatic zog.

(6) Zoo stability thiab zoo heev tshuaj tiv thaiv.Epoxy resin tsis muaj alkali, ntsev thiab lwm yam impurities tsis yooj yim rau deteriorate.Tsuav nws khaws cia kom zoo (sau, tsis muaj dej noo thiab kub), lub sijhawm cia yog 1 xyoos.Tom qab hnub tas sij hawm, yog tias qhov kev kuaj xyuas tsim nyog, nws tseem tuaj yeem siv tau.Epoxy curing compound muaj tshuaj lom neeg zoo heev.Nws corrosion kuj rau alkali, acid, ntsev thiab lwm yam xov xwm yog zoo dua li ntawm unsaturated polyester resin, phenolic resin thiab lwm yam thermosetting resins.Yog li ntawd, epoxy resin yog dav siv los tiv thaiv corrosion primer.Vim hais tias cov kho epoxy resin muaj peb-dimensional network qauv thiab tuaj yeem tiv taus cov roj impregnation, nws yog dav siv nyob rau hauv lub puab phab ntsa hauv ob sab phlu ntawm cov roj tso tsheb hlau luam, roj tankers thiab aircraft.

Daim duab 1 cov yeeb nkab hluav taws (5 pieces)

(7) Lub tshav kub tsis kam ntawm epoxy curing compound feem ntau yog 80 ~ 100 ℃.Lub tshav kub-resistant ntau yam ntawm epoxy resin tuaj yeem ncav cuag 200 ℃ lossis siab dua.
