Polycarboxylic Acid Wakiilka Yaraynta Biyaha La taaban karo (PCE)– Halbeegyada Muhiimka ah ee la taaban karo

Tilmaamaha Waxtarka

Wakiilkan hoos u dhiga biyaha ee polycarboxylic acid waxa uu bixiyaa awoodda yaraynta biyaha adag. Waxay hoos u dhigi kartaa biyaha ku jira shubka 25% ku 40% iyada oo aan saameyn ku yeelan kartida shaqada. Shayga wuxuu ilaaliyaa isku dhafka shubka ah dareeraha oo fudud in la dhigo, xitaa marka la eego saamiga biyaha-sibidhka ee hooseeya.

Qiyaasta qiyaasta

Qiyaasta lagu taliyey waa 0.15% ku 0.35% miisaanka alaabta sibidhka. Isticmaalka dhabta ah wuxuu ku tiirsan yahay nooca shubka ah, naqshadaynta isku dhafka ah, oo uu rabay niyad jab. Si joogto ah u socodsii dufcad tijaabo ah ka hor isticmaalka weyn.

Waafaqid

Wakiilka PCE-ga wuxuu si fiican ula shaqeeyaa wax badan oo shub ah oo magaalada Rose ah, dharbaaxo, dambas duuli, iyo qiiqa silica. Waxa kale oo ay si hufan ugu dhex dartaa isku-darka kale ee caadiga ah sida wakiilada hawo-mareenka ama dib-u-dhigayaasha. Weli, tijaabi iswaafajinta marka la bedelayo agabka agabka.

Dejinta Waqtiga

Alaabtani waxay saameyn yar ku leedahay waqtiyada dejinta hordhaca ah iyo kan ugu dambeeya ee dhibaatooyinka caadiga ah. Cimilada qabow ama sibidhyada qaarkood, xirid yar ayaa dhici karta. Isbeddellada waxaa lagu samayn karaa isku-dar-dardargelineed haddii loo baahdo.

Horumarka Adag

La taaban karo oo lagu sameeyay PCE-gan ayaa muujinaya faa'iido hore oo degdeg ah. Adkaynta cadaadiska hal-maalin ah ayaa badiyaa dhaafa 20 MPa. Marka 28 maalmo, xoog kor u by 20% ku 30% marka la barbar dhigo isku dhafka aasaasiga ah oo aan lahayn biyo-yareeya heer-sare.

Ku-haynaanshaha dhumucda

Wakiilku wuxuu bixiyaa haynta hoos-u-dhac heersare ah qiyaastii 90 daqiiqado. Tani waxay ka dhigaysaa mid ku habboon shixnadaha diyaarsan ee muddada dheer ama wax-soo-saarka cimilada kulul. Hoosudhaca hoos u dhaca ayaa ku hadhay 25 mm inta badan daaqadan oo dhan.

Waxyaabaha ku jira shabakadda Chloride

Shayga kuma jiro chlorides oo lagu daray. Waxay buuxinaysaa shuruudaha ASTM C494/C494M ee nooca F iyo G ee isku-dhafka biyaha-yareeya.

Goobta kaydinta iyo wax ka qabashada

Ku kaydi weelasha asalka ah heerkulka u dhexeeya 5 ° C iyo 35 ° C. Iska ilaali qabowga. Rux ama walaaq ka hor inta aan la isticmaalin haddii kala qaybsanaantu dhacdo. Nolosha adeeggu waa hal sano marka si wax ku ool ah loo badbaadiyo.

Codsiyada Polycarboxylic Acid Wakiilka Yaraynta Biyaha la taaban karo ee PCE

Codsiyada Polycarboxylic Acid Wakiilka Yaraynta Biyaha la taaban karo (PCE) ee la taaban karo Premixed

Boosted Workability and Flow

Polycarboxylic acid-based water minimizing agents, or PCEs, substantially boost the flow of premixed concrete. They allow the mix to remain fluid longer without including extra water. This makes putting and placing less complicated on site. Professionals get smooth, regular outcomes also in complicated kinds or limited areas.

Ka Awood Badan, La taaban karo cufan

By reducing the water web content while maintaining workability high, PCEs aid generate stronger concrete. Less water suggests fewer spaces after treating. The last framework ends up being denser and extra resilient. This is specifically helpful for high-strength applications like bridges, dhismayaal dhaadheer, iyo sagxadaha warshadaha.

Better Control Over Setup Time

PCE admixtures give producers better control over exactly how quick concrete collections. Tani waxay aad muhiim ugu tahay cimilada kulul ama muddada dheer ee geedka ilaa goobta shaqada. Caanaha PCE ee saxda ah waxay ilaalinaysaa isku darka ilaa ay isu diyaarinayso in la dhigo, hoos u dhigista qashinka iyo dib u habeynta.

La xoojiyay Tayada Dhamaystiran iyo Dusha sare

La taaban karo oo lagu sameeyay PCE waxay muujinaysaa arrimo ka yar oogada. Waxay ka hortagtaa kala soocidda iyo luminta dhiigga, kuwaas oo sida caadiga ah abuura malabka ama dhibco daciif ah. Natiijadu waa nadiif, dhammayn labis dheeraad ah– ugu fiican ee dhinacyada dhismaha ee la muujiyey ama muraayadaha hore loo dhejiyey.

Waafaqid iyo Joogteynta

Alaabooyinka PCE-ga casriga ah waxay si fiican ugu shaqeeyaan shubmooyin kala duwan, agabka kaalmeeya sida dambaska duqsiga ama dharbaaxada, iyo admixtures kale duwan ee caadiga ah. Dabacsanaantu waxay caawisaa iibiyeyaasha diyaarka ah ee isku darka ah inay ilaaliyaan joogteynta dufcada-ilaa-dufcada. Hufnaanta la isku halayn karo waxay ka dhigan tahay dib u dhacyo yar iyo habsocod fudud oo ku yaal bogga internetka.

Waxtarka Joogtada ah

Sababtoo ah PCE-yadu waxay hoos u dhigaan shuruudaha biyaha iyo kuwa la taaban karo iyada oo aan waxyeello loo geysan xoogga, waxay taageeraan dhismo cagaaran. Isticmaalka sibidhka oo la dhimay wuxuu gooyaa kaarboon moono-oksaydh laba qiiqa. Isla markaana, Awood-shaqaynta muddada dheer waxay yaraynaysaa baahida loo qabo safarro baabuur oo dheeraad ah ama dib-u-celin, ilaalinta shidaalka iyo shaqada.

5 FAQs of Polycarboxylic Acid Wakiilka Yaraynta Biyaha la taaban karo ee PCE ee la taaban karo

Su'aalaha Inta Badan La Isweydiiyo ee Ku Saabsan Polycarboxylic Acid (PCE) Wakiilka Yaraynta Biyaha ee la taaban karo ee la isku daray

Waa maxay wakiilka biyaha yareeya PCE?

Wakiilka biyaha yareeya PCE waa kiimiko wax qabad sare leh oo loo isticmaalo shubka premixed. Waxay yaraynaysaa cadadka biyaha loo baahan yahay iyadoo la ilaalinayo shamiitada shaqaynaysa. Tani waxay gacan ka geysaneysaa soo saarista xooggan, la taaban karo oo dheeraad ah oo aan la beddelin naqshadeynta isku dhafka ah.

Maxay tahay sababta loo isticmaalo PCE halkii aad ka isticmaali lahayd biyo-yaraynta kale?

PCE offers better water reduction than traditional agents like naphthalene or lignosulfonate types. It gives higher slump retention, which means the concrete stays easy to pour and place over time. It also works well with different cements and mineral additives.

How does PCE improve concrete strength?

Adigoo jaraya waxa ku jira biyaha, PCE lowers the water-cement ratio. A lower ratio directly leads to higher compressive and flexural strength. The concrete becomes denser, which also improves its resistance to water penetration and chemical attack.

Is PCE compatible with other admixtures?

Haa, PCE generally mixes well with common admixtures like air-entraining agents, dib u dhigista, ama dardargeliyayaasha. Weli, had iyo jeer tijaabi isku dhafka buuxa ka hor isticmaalka ballaaran. Qaar ka mid ah isku-darka ayaa laga yaabaa inay saameeyaan dejinta waqtiga ama karti-gelinta shaqada.

Waa maxay qiyaasta aan isticmaalo?

Qiyaasta caadiga ah waxay u dhexeysaa 0.15% ku 0.35% miisaanka sibidhka. The exact amount depends on the desired slump, nooca sibidhka, iyo xaaladaha deegaanka. Ka bilow talada alaab-qeybiyaha oo ku hagaaji iyada oo ku saleysan dufcadaha tijaabada ah. PCE-ga oo aad u badan wuxuu keeni karaa kala sooc ama dib u dhac xad dhaaf ah.
