Kev txau epoxy thiab txheej Halar

I. Dab tsi yog epoxy tsuag txheej?

Epoxy tsuag txheej yog ob-component txheej nrog epoxy resin ua cov khoom tseem ceeb-tsim zaj duab xis. Nws yog siv rau ntawm qhov chaw hlau los ntawm kev tsuag lossis txhuam kom tsim ib txheej tiv thaiv. Nws yog tus cwj pwm los ntawm kev nplaum zoo thiab zoo heev tiv thaiv cathodic peeling. Ib txheej txheej tuaj yeem ua tiav cov qauv tsim tuab (txog li 1250 microns) yam tsis muaj sagging. Nws yog kho ntawm chav tsev kub thiab yooj yim rau kev tsim kho. Epoxy txheej yog tsim rau kev yaig thiab kev tiv thaiv xeb ntawm cov kav dej, cov thawv, twj tso kua mis thiab cov li qub thiab lwm yam khoom siv, thiab qhov kub ua haujlwm feem ntau tuaj yeem ncav cuag li 120 ° C.

II. Halar txheej yog dab tsi?

Halar yog lub npe lag luam ntawm ECTFE (ethylene-chlorotrifluoroethylene copolymer) fluoropolymer hmoov txheej, uas yog cov khoom siv muaj fluorine ua tau zoo. Nws yog siv rau ntawm qhov chaw ntawm cov hlau substrates los ntawm cov txheej txheem electrostatic spraying, nrog rau qhov chaw yaj ntawm 220-245 ° C thiab qhov kub siab tshaj plaws siv tas mus li ntawm 150 ° C.

III.Qhov txawv ntawm kev tiv thaiv xeb tshuaj lom neeg ntawm ob qho no yog dab tsi?

Cov txheej txheej Halar muaj ntau yam thiab zoo dua hauv kev tiv thaiv tshuaj lom neeg. Nws tuaj yeem tiv taus yuav luag txhua cov kua qaub muaj zog, cov hauv paus muaj zog thiab cov kuab tshuaj organic nrog pH ntawm 1-14. Nws tuaj yeem raug tsau tas li hauv cov tshuaj lom neeg hnyav xws li 98% concentrated sulfuric acid thiab 37% hydrochloric acid ntawm 121 ° C rau 30 hnub. Qhov hnyav ntawm txheej txheej hloov pauv tsawg dua 1% thiab cov khoom siv kho tshuab tsis muaj kev hloov pauv tseem ceeb. Nws muaj hydrophobicity zoo heev thiab kev tiv thaiv nkag mus, uas tuaj yeem tiv thaiv cov xov xwm corrosive los ntawm kev nkag mus rau hauv txheej txheej thiab ncav cuag cov hlau substrate. Txawm hais tias cov txheej txheej epoxy kuj muaj kev tiv thaiv tshuaj lom neeg zoo, lawv lub peev xwm los tiv taus cov kua qaub muaj zog (xws li sulfuric acid, hydrochloric acid) thiab qhov kub siab yog qhov tsis muaj zog dua li cov txheej txheej Halar.

IV.Qhov twg zoo dua ntawm kev ua tau zoo ntawm qhov chaw thiab kev ua haujlwm ntev?

Qhov saum npoo ntawm Halar txheej yog du heev (qhov nruab nrab roughness Ra tsuas yog li 22nm), uas zoo dua li txheej epoxy. Qhov saum npoo du tuaj yeem tiv thaiv kev sib txuas thiab kev sib sau ua ke ntawm cov khoom me me thiab cov ntsev hlau, txo qhov tsim ntawm biofilm, txo qhov kev pheej hmoo ntawm pinholes, thiab txhim kho kev ntseeg siab tiv thaiv xeb. Tsis tas li ntawd, Halar txheej yog tawv, tiv taus khawb thiab cuam tshuam, thiab muaj zog tiv taus UV, yog li nws yuav tsis ploj lossis ploj thaum siv sab nraum zoov.

V. Yuav ua li cas xaiv cov tshuaj pleev kom haum?

Nws raug pom zoo kom xaiv Halar txheej thaum——

1. Tiv tauj nrog cov kua qaub muaj zog, cov alkali muaj zog lossis cov tshuaj sib xyaw ua ke;

2. Qhov kub ua haujlwm tshaj 120 ℃ (siab tshaj 150 ℃);

3. Sab nraum zoov lossis muaj zog ultraviolet ib puag ncig;

4. Yuav tsum muaj ib qho chaw du heev kom tiv thaiv cov khoom me me kom tsis txhob lo rau;

Nws raug pom zoo kom xaiv cov txheej epoxy hauv cov xwm txheej hauv qab no:

1. Ib puag ncig tsis muaj zog lossis tsis muaj zog corrosive, kub hauv qab 120 ° C;

2. Lub sijhawm tsim kho tsis ntev thiab xav tau kev kho sai;

3. Kev tswj tus nqi yog qhov nruj heev.
