1.Puas carbon steel / stainless hlau lined nrog fiberglass pom zoo?
Tsis pom zoo.
Teeb meem: Txias dov pickling siv siab -kub hydrochloric acid, uas muaj zog heev chloride ion nkag mus rau lub zog. Yog hais tias muaj pinholes nyob rau hauv fiberglass (FRP) hauv ob sab phlu ntawm carbon steel, cov hydrochloric acid yuav instantly corrode cov carbon steel substrate, ua perforation nyob rau hauv hnub.
Qhov xwm txheej tam sim no: Tsuas yog siv rau hauv ntu dej los yog hauv txoj kev qub sulfuric acid pickling.
2.Dab tsi yog qhov kev txiav txim siab tseem ceeb thaum xaiv granite/acid-cov vuas ceramic resistant?
Kev Cai Xaiv:
Khoom siv:
Yuav tsum yog Qingdao Bluestone lossis Jinan Bluestone (diabase), ntom thiab tawg -dawb.
Sandstone raug txwv nruj heev; nws cov porosity siab ua rau muaj kev pheej hmoo ntawm to.
Grouting:
Grouting pob qij txha yog qhov tsis muaj zog. Potassium silicate grout los yog furan resin grout yuav tsum tau.
Kev zam: Ordinary cement grout yuav inevitably xau hauv 7 hnub.
Temperature: Excellent temperature resistance (>150 degree), tsis muaj kev laus.
Lifespan: Ntau tshaj 20 xyoo.
Kev phom sij:
Hnyav, yuav tsum muaj lub hauv paus zoo - zoo.
Tsis yooj yim los soj ntsuam cov xau: Cov kua qaub nkag mus rau hauv cov pob qij txha, tsis tuaj yeem tawm sab nraud, tab sis ncaj qha corroding lub hauv paus steel reinforcement.
Kev kho yuav tsum tau kaw thiab pob zeb chiseling, nrog rau lub sij hawm tsim kho nyob rau hauv lub lis piam.
3.Yuav ua li cas txog Hastelloy C276?
Daim ntaub ntawv: Pickling ntawm titanium thiab titanium alloys, kuaj daim ntawv thov, thiab siab - qhov kub thiab txias nrog ntim me me.
Txias -kwv yees kab hydrochloric acid tsis tshua siv C276 vim:
Nqe: C276 yog npib tsib xee-raws li alloy, raug nqi ntau tshaj 100 npaug tshaj PPH.
Tsis tsim nyog: Thaum hydrochloric acid yeej tiv taus C276, qhov kub ntawm qhov txias txias -rolled carbon steel tsis siab (<100℃), making PPH and granite perfectly adequate.
Kev zam: Qee zaus, C276 yog siv los ua ib lub hauv ob sab phlu rau kev tiv thaiv hauv zos hauv acid regeneration thiab concentration (high temperature, high chloride ion, abrasive).
4.Yuav ua li cas txiav txim siab rau kev xaiv ntawm lub txias dov pickling tank?
Ua ntej, xav txog qhov kub thiab txias:
Acid kub ≤90℃→ PPH (tus nqi zoo tshaj rau cov nyiaj).
Acid kub 90-100℃→ Granite los yog imported high-temperature PPH (chaw tsim tshuaj paus qhov ntsuas kub kuj yuav tsum tau).
Acid temperature >100℃→ Tsuas yog granite/acid-cov bricks resistant yog haum.
Tom ntej no, xav txog qhov ntim / ntev:
Extra-long tanks (>40 meters) → Granite segmented (uniform thermal expansion).
Cov tso tsheb hlau luam luv / cov nkoj hauv av → PPH (kev tsim khoom sai, kev saib xyuas yooj yim).
Thaum kawg, xav txog kev nkag mus saib xyuas:
Cov kab ntau lawm uas tsis tuaj yeem zam tau ntev - lub sijhawm kaw → PPH modularization raug pom zoo; yog tias puas lawm, tshem tawm ib daim thiab hloov nrog ib qho khoom seem.
Tau txais lub sijhawm txij nkawm ntau tshaj ib nrab ib hlis → Granite.
5.Txawm li cas los xij ntawm cov khoom xaiv, dab tsi yuav tsum tau ua raws li lub tank qauv?
Classic tsis ua hauj lwm piv txwv: Ib tug zoo nkauj nteg granite paving nto tau nthuav tawm, nrog lub hauv paus pob zeb ncaj qha hu rau granite.
Qhov tshwm sim: Ib qho me me tshwm sim hauv cov pob qij txha, tso cai rau cov kua qaub nkag mus rau hauv cov pob zeb, ua rau nws nthuav, hmoov, thiab thaum kawg tawg.
Txoj hauv kev kom raug: Ib txheej fiberglass (vinyl ester resin) waterproofing txheej yuav tsum tau siv rau hauv qab ntawm granite paving, nrog granite so rau sab saum toj ntawm fiberglass.
