Isku-darka Wakiilada Yaraynta Biyaha ee Polycarboxylic Acid
JF POLYCARBOXYLATE SUPERPLASTICIZER Sharaxaada Alaabta:
La mid ah: Biyo yaraynta PCE
Polycarboxylic acid Biyo-yareeyaha Xalka Saamiga (dhamaystiran) Xalka Biyo-yareeyaha Polycarboxylic acid waa jiil cusub oo biyo-yareeya wax-qabad sare leh oo ay si madax-bannaan u soo saartay shirkadeena.Waa wax qabad heersare ah oo dhammaystiran oo biyo-yareeya oo ah kobolymer-ka-tallaalidda aashitada karboksilic.(Biyo-yaraynta sare iyo haynta balaastikada) Alaabtani waxay leedahay sifooyinka isticmaalka tamarta wax-soo-saarka hooseeya, ma jiro formaldehyde iyo ma laha qashinka wax-soo-saarka.Waa wax soo saarka tamarta-badbaadinta iyo deegaanka-saaxiibtinimo.Tusaha waxqabadka isku-dhafan ee ay leedahay ayaa gaadhay heerka ugu horreeya gudaha iyo dibaddaba.Alaabtan ayaa si weyn loogu isticmaalay ilaalinta biyaha, korontada, dekedda, jidka tareenka, buundada iyo mashaariicda kale.

Polycarboxylic acid waxtarka sare leh ee hoos u dhigaya waxqabadka wakiilka:
1. Qaab dhismeedka molecular ee gaarka ah iyo qaab dhismeedka laanta gaarka ah, kaas oo loo isticmaalo falcelinta hydrolysis ee shubka cusub.Iyadoo la hagaajinayo qaab dhismeedka laanta, heerka hydrolysis waxaa lagu hagaajin karaa wakhtiga waxtarka leh si loo gaaro saameynta ilaalinta xulashada.
2. Hantida si tartiib tartiib ah loo sii daayo, Alaabtani waxay ku dhex milmay la taaban karo, si tartiib tartiib ah hydrolyzed, sii daaya kooxaha karboksylic acid si loo gaaro saamayn firidhsan muddo dheer waarta, gaadhista saamaynta ilaalinta ku habboon.
3. Heerka korodhka xoogga sare, la taaban karo oo lagu qaso badeecadu ma beddeleyso wakhtiga dejinta, waxay ka gudubtaa cilladaha dib-u-dejinta guud si ay u sameyso wakhtiga ugu dambeeya ee la taaban karo oo aad u dheer, iyo horumarinta xoogga hore waa mid aad u gaabis ah.
Saamaynta qiimaha PH ee wakiilka yaraynta biyaha polycarboxylic:
1. Kor u kaca qiimaha PH, saamiga xoogga cufan ee shubka ayaa u muuqda inuu kordho wax yar, laakiin xooggu si weyn uma beddelo marxaladda dambe.
2. Kor u kaca qiimaha PH, heerka yaraynta biyaha bilowga ah ee la taaban karo ma laha isbeddel muuqda, laakiin hoos u dhaca iyo balaadhinta la taaban karo ayaa si cad u yaraaday hal saac oo lumis ah.
3. Kor u kaca qiimaha PH, nuxurka gaasta ee shubka ah ma laha isbeddel muuqda, laakiin viscosity ee shubka ayaa kordha iyo xawaaraha socodka ayaa hoos u dhacaya.
4. Kor u kaca qiimaha PH, saamiga xoogga cufan ee la taaban karo wuxuu kordhiyaa wax yar da'da, laakiin xoogga si weyn uma beddelo marxaladda dambe.
Tilmaamaha alaabta:
1. Heerka yaraynta biyaha oo sarreeya
2. adhesion wanaagsan
3. Heerka koritaanka xoogga sare
4. Xoog iyo adkeysi wanaagsan
5. La qabsiga wanaagsan
6. Cagaar: ma jiro formaldehyde iyo maaddooyinka kale ee waxyeellada leh.
Ka taxadaritaan:
1. Alaabtani waa mid aan sun ahayn oo aan waxyeello lahayn, wax-soo-saarka, laakiin aan la cuni karin.
2. Haddii ay indhaha gasho, waa in lagu dhaqaa biyo badan waqtigeeda.
3. Haddii aad xasaasiyad ku keento qayb ka mid ah jidhka bini'aadamka, waa inaad la tashataa dhakhtarka wakhtiga.
