I-Polycarboxylate(PCE, iPolycarboxylate Ether) sisixhobo esibalulekileyo sekhemikhali esisetyenziswa kakhulu kwiikhemikhali zokwakha, ingakumbi kwimilo yekhonkrithi esebenza kakhulu. Ngenxa yokukwazi kwayo ukusasaza kunye nokuhambelana kwayo neenkqubo ezahlukeneyo zesamente, iimveliso ezisekwe kwi-polycarboxylate ziye zaba yinxalenye ebalulekileyo kubuchwepheshe banamhlanje bokudibanisa ikhonkrithi.

Ukuphucula ukusebenza kakuhle kokusasazwa kwesamente

Kwimveliso yekhonkrithi, ukugcina ukusebenza kakuhle ngelixa kunciphisa ukusetyenziswa kwamanzi ngumceli mngeni ophambili kubavelisi. Izongezo ezisekelwe kwi-polycarboxylate zinceda ukuphucula ukusasazeka kwamasuntswana esamente, zivumela umxube wekhonkrithi ukuba ufumane ukunyibilika okungcono kunye nokuzinza ngokusetyenziswa kwamanzi okuphuculweyo.

Xa kuthelekiswa nee-arhente zemveli zokunciphisa amanzi, iimveliso ze-polycarboxylate zibonelela ngokuguquguquka okukhulu kuyilo lwefomyula. Zisetyenziswa rhoqo kwizicelo ezifuna ukusebenza okuphezulu, kubandakanya ikhonkrithi exutywe kakuhle, ikhonkrithi elungisiweyo, kunye neeprojekthi zekhonkrithi ezinamandla aphezulu.

Ukubaluleka kwezixhobo zokwakha ezisebenza kakuhle

Njengoko iiprojekthi zokwakha zifuna izinto ezihlala ixesha elide kwaye zisebenza kakuhle ekucubunguleni, ii-superplasticizers ezisekelwe kwi-polycarboxylate zisetyenziswa kakhulu kwiinkqubo ezahlukeneyo zekhonkrithi.

Iingenelo zabo ziquka:

• Ukuphucula ukuhamba kwamanzi kwekhonkrithi;
• Ukugcinwa okungcono kokusebenza;
• Ukuncipha kwemfuno yamanzi;
• Ukuhambelana nezinto ezahlukeneyo zesamente.

Ezi mpawu zenza i-polycarboxylate ibe yinxalenye ebalulekileyo ekuphuhlisweni kwezinto zokwakha zanamhlanje.

Ukuhambelana Komgangatho Kubalulekile Kubathengi Bemizi-mveliso

Kubavelisi bezinto ezixutywayo zekhonkrithi, uzinzo lomgangatho weemveliso ze-polycarboxylate luchaphazela ngokuthe ngqo ukusebenza komxube wokugqibela. Ngexesha lokuthenga, abathengi badla ngokugxila koku kulandelayo:

• Ukusebenza kweekhemikhali okuzinzileyo phakathi kweebhetshi;
• Ukuhambelana neentlobo ezahlukeneyo zesamente;
• Umxholo oqinileyo ohlala uhleli kunye neeparameter zobugcisa;
• Ubuchule bokubonelela obunokuthenjwa.

Ubonelelo oluzinzileyo lwezinto eziluhlaza lunceda abavelisi ukuba bagcine umgangatho wemveliso ungaguquguqukiyo kwaye baphucule ukusebenza kakuhle kwemveliso.

Izinto ekufuneka ziqwalaselwe kukugcinwa nokuphathwa

Iimveliso zePolycarboxylate mazigcinwe phantsi kweemeko ezifanelekileyo ukuze zigcine ukusebenza kwazo. Abasebenzisi bemizi-mveliso ngokubanzi banika ingqalelo kubushushu bokugcina, ukuthembeka kokupakishwa, kunye nokukhuselwa ekungcoleni ngexesha lokuthuthwa.

Ulawulo olufanelekileyo lokugcina imveliso lunceda ukugcina uzinzo kwaye luqinisekisa ukusetyenziswa kakuhle kwiifomyula ezisezantsi.

Ukuxhasa uPhuhliso lweeKhemikhali zoKwakha eziPhambili

Ngenxa yendima yayo ebalulekileyo kwiinkqubo zokudibanisa i-concrete, i-polycarboxylate iyaqhubeka nokuxhasa uphuhliso lwezixhobo zokwakha ezisebenzayo nezizinzileyo. Amandla ayo okuphucula ukusebenza kwezinto ngelixa iphucula uyilo lwefomyula iyenza ibe yinxalenye ebalulekileyo yeekhemikhali kumashishini okwakha anamhlanje.

Kubathengi bemizi-mveliso, umgangatho wemveliso othembekileyo, inkxaso yobuchwephesha, kunye nokukwazi ukubonelela okuzinzileyo kuhlala kuyizinto ezibalulekileyo xa ukhethai-polycarboxylateababoneleli.
