Funda malunga nezongezo zekhemikhali eziphambili kwi-mex-mix mortar

I-Ready-mix mortar yinto yokwakha eyilelwe ukusetyenziswa kwiiprojekthi zokwakha.Yenziwe ngokuxuba i-samente, isanti kunye namanzi ngomlinganiselo ohlukeneyo, kuxhomekeke kumandla afunwayo kunye nokuhambelana kwemveliso egqityiweyo.Ukongeza kwezi zithako ezisisiseko, udaka olulungele ukuxuba kwakhona luqulethe uluhlu lwezongezo zekhemikhali ezilungiselelwe ukuphucula ukusebenza kwayo kunye nokuqina.

Izongezo zemichiza zizinto ezongeziweyo kwizinto zokuphucula okanye ukuguqula iimpawu zayo.Kwimibhobho esele ilungile, ezi zongezo zihlala zikhethwa ngenxa yokukwazi ukuphucula ukusebenza, ukunciphisa ixesha lokumisela, ukwandisa ukugcinwa kwamanzi, kunye nokuphucula amandla kunye nokuqina kwemveliso egqityiweyo.

Kweli nqaku siza kujonga ezinye zezongezo zekhemikhali eziphambili eziqhelekileyo ezisetyenziswa kwimveliso yodaka esele ilungile.

1.Umnciphisi

I-retarders iklasi yezongezo zeekhemikhali ezisetyenziselwa ukunciphisa ixesha lokumisela izinto ezisekelwe kwi-samente.Basebenza ngokulibazisa ukusebenza kwemichiza okwenzeka xa isamente idibana namanzi, nto leyo enika abasebenzi ixesha elingakumbi lokugqiba umsebenzi ngaphambi kokuba udaka lufakwe.

Iiretaretha ziluncedo ngakumbi kwiimeko zemozulu eshushu okanye xa zisebenza ngodaka oluninzi, olunokuthi lusekwe ngokukhawuleza.Ngokuqhelekileyo zongezwa kumxube wodaka kwizinga le-0.1% ukuya kwi-0.5% yesiqulatho sesamente.

2. Iplastiki

Iiplastiki zolunye uhlobo lwezongezo zeekhemikhali ezisetyenziswa ngokuqhelekileyo kwiimbumba ezisele zixutywe.Injongo yabo kukunciphisa i-viscosity yodaka, okwenza kube lula ukuphatha nokusebenzisa.

Iiplastiki zidla ngokudityaniswa kumxube wodaka kwisantya se-0.1% ukuya kwi-0.5% yesiqulatho sesamente.Baphucula iimpawu zokuhamba komdaka, okwenza kube lula ukusabalalisa kunye nokufezekisa umphezulu womgangatho ofanayo.

3. Iarhente yokugcina amanzi

I-agent yokugcinwa kwamanzi luhlobo lwezongezo zeekhemikhali eziphucula ukusebenza kokugcina amanzi kwidaka.Injongo yabo kukunciphisa ubuninzi bamanzi alahlekileyo ngokunyuka kwamanzi ngexesha lenkqubo yokunyanga, okunceda ukuthintela ukushwabana nokuqhekeka.

Iiarhente zokugcina amanzi zidla ngokudityaniswa kumxube wodaka ngesantya se-0.1% ukuya kwi-0.2% yesiqulatho sesamente.Baphucula ukusebenza kodaka, okwenza kube lula ukuyifaka kunye nokufezekisa i-smooth, even surface.

4. I-arhente yokungenisa umoya

Ii-agent zokungenisa umoya zisetyenziselwa ukwazisa amaqamza amancinci omoya kumxube wodaka.La maqamza asebenza njengezinto ezincinci zokufunxa ukothuka, okonyusa ukuqina kunye nokumelana nokunyibilika kwemveliso egqityiweyo.

Ii-agent zokungenisa umoya zongezwa ngokuqhelekileyo kumxube wodaka kwizinga le-0.01% ukuya kwi-0.5% yesiqulatho sesamente.Banokuphucula ukusebenza kodaka kwaye benze kube lula ukufaka isicelo, ngakumbi xa usebenza ngee-aggregates ezinzima.

5. I-Accelerator

I-accelerators izongezo zekhemikhali ezisetyenziselwa ukukhawulezisa ixesha lokubeka udaka.Ngokuqhelekileyo zisetyenziswa kwiimeko ezibandayo zemozulu okanye xa udaka kufuneka lugqitywe ngokukhawuleza.

Ii-accelerators zivame ukufakwa kumxube wodaka kwizinga le-0.1% ukuya kwi-0.5% yesiqulatho se-samente.Zinokunceda ukunciphisa ixesha elithathwayo ukuze udaka lunyange kwaye lufikelele kumandla apheleleyo, nto leyo ebalulekileyo kwiiprojekthi zokwakha ezithatha ixesha.

6. I-arhente yokunciphisa amanzi ngobuchule obuphezulu

I-Superplasticizer yiplastiki esetyenziselwa ukunyusa ukusebenza kodaka.Basebenza ngokusabalalisa amaqhekeza e-samente ngokulinganayo kulo lonke umxube wodaka, ngaloo ndlela bephucula iimpawu zayo zokuhamba.

I-Superplasticizers idla ngokudibaniswa kumxube wodaka kwizinga le-0.1% ukuya kwi-0.5% yesiqulatho sesamente.Baphucula ukusebenza kodaka, okwenza kube lula ukuyifaka kunye nokufezekisa i-smooth, even surface.

I-Ready-mix mortar yinto yokwakha eyaziwayo esetyenziswa ngokubanzi kwiiprojekthi ezahlukeneyo zokwakha.Iqukethe umxube wesamente, isanti kunye namanzi, kunye noluhlu lwezongezo zekhemikhali ezisetyenziselwa ukuphucula ukusebenza kwayo kunye nokuqina.

Ezinye zezongezo zekhemikhali eziphambili ezisetyenziswa kudaka olusele luxutyiwe ziquka iiretarders, iiplasticizers, ii-agent ezigcina amanzi, ii-air intraining agents, ii-accelerators kunye ne-superplasticizers.Ezi zongezo zikhethwe ngononophelo ukuphucula ukuqhutyelwa phambili, ukunciphisa ixesha lokumisela, ukwandisa ukugcinwa kwamanzi kunye nokuphucula amandla kunye nokuqina kwemveliso egqityiweyo.

Ngokuqonda indima yezongezo zekhemikhali nganye, iingcali zokwakha zinokukhetha uhlobo oluchanekileyo lodaka olulungele ukuxuba kwiprojekthi yabo ethile kunye nokuqinisekisa ukuba ihlangabezana neemfuno zayo zokusebenza kunye nokuqina.
