Hom kev sib txuas ntawm cov yeeb nkab hluav taws: xov, qhov zawj, flange, thiab lwm yam. Cov yeeb nkab hlau epoxy sib xyaw sab hauv thiab sab nraud rau kev tiv thaiv hluav taws yog cov hmoov epoxy resin tiv thaiv xeb uas tau hloov kho hnyav, uas muaj kev tiv thaiv tshuaj lom neeg zoo heev. Nws daws tau ntau yam teeb meem xws li kev xeb ntawm qhov chaw thiab phab ntsa sab hauv ntawm cov khoom zoo sib xws tom qab siv ntev, kom tsis txhob muaj kev thaiv sab hauv uas cuam tshuam rau kev siv, kom txhim kho lub neej ua haujlwm ntawm cov yeeb nkab tua hluav taws tshwj xeeb. Vim yog ntxiv cov khoom siv tiv thaiv hluav taws hauv cov ntaub ntawv txheej, qhov kub thiab txias ntawm cov khoom tau zoo dua piv rau lwm cov khoom zoo sib xws. Yog li ntawd, nws yuav tsis cuam tshuam rau kev siv thaum qhov kub thiab txias ib puag ncig nce siab. Lub neej ua haujlwm thiab kev ua haujlwm ntawm cov yeeb nkab hluav taws sab hauv thiab sab nraud zoo dua li cov yeeb nkab galvanized. Xim yog liab.

Peb lub Hoobkas tshwj xeeb hauv kev tsim cov yeeb nkab hluav taws, cov yeeb nkab hlau galvanized, cov yeeb nkab hmoov txheej, cov yeeb nkab hmoov txheej thiab cov yeeb nkab hlau 6-nti. Daim ntawv thov: kev muab dej tua hluav taws, kev muab roj thiab cov raj xa dej ua npuas ncauj. Cov khoom zoo dhau qhov kev lis kev cai thiab dhau ntau qhov kev sim ua ntej tawm hauv lub Hoobkas. Ua raws li cov qauv zoo hauv tebchaws thiab thoob ntiaj teb.

(1) Cov khoom siv kho tshuab siab. Epoxy resin muaj kev sib koom ua ke zoo thiab cov qauv molecular ntom ntom, yog li nws cov khoom siv kho tshuab siab dua li cov thermosetting resins dav dav xws li phenolic resin thiab unsaturated polyester.

(2) Cov txheej txheem ntawm cov yeeb nkab yas coated hluav taws siv epoxy resin, uas muaj kev nplaum zoo. Epoxy resin curing system muaj epoxy pawg, hydroxyl pawg, ether bond, amine bond, ester bond thiab lwm cov pawg polar nrog kev ua haujlwm zoo, uas muab cov khoom kho epoxy zoo heev rau hlau, ceramics, iav, pob zeb, ntoo thiab lwm yam polar substrates.

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

(4) Ua haujlwm zoo. Epoxy resin feem ntau tsis tsim cov khoom tsis tshua muaj molecular thaum lub sijhawm kho, yog li nws tuaj yeem tsim nyob rau hauv qhov siab qis lossis qhov siab sib cuag. Nws tuaj yeem koom tes nrog ntau tus neeg sawv cev kho kom tsim cov txheej txheem ib puag ncig xws li cov tshuaj tsis muaj kuab tshuaj, cov khoom khov kho siab, cov txheej txheem hmoov thiab cov txheej txheem dej.

(5) Kev rwb thaiv hluav taws xob zoo heev. Epoxy resin yog cov thermosetting resin nrog cov khoom tiv thaiv zoo.

(6) Kev ruaj khov zoo thiab tiv taus tshuaj lom neeg zoo heev. Epoxy resin tsis muaj alkali, ntsev thiab lwm yam tsis huv tsis yooj yim puas. Tsuav yog nws khaws cia kom zoo (kaw, tsis muaj dej noo thiab kub siab), lub sijhawm khaws cia yog 1 xyoos. Tom qab hnub tas sij hawm, yog tias kev tshuaj xyuas tau tsim nyog, nws tseem siv tau. Epoxy curing compound muaj kev ruaj khov tshuaj lom neeg zoo heev. Nws qhov kev tiv thaiv corrosion rau alkali, acid, ntsev thiab lwm yam xov xwm zoo dua li cov polyester resin tsis muaj roj, phenolic resin thiab lwm yam thermosetting resins. Yog li ntawd, epoxy resin yog siv dav ua primer tiv thaiv xeb. Vim tias cov epoxy resin kho muaj cov qauv network peb-seem thiab tuaj yeem tiv taus cov roj impregnation, nws yog siv dav hauv phab ntsa sab hauv ntawm cov roj tank, cov roj tanker thiab dav hlau.

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