Udaka oluxutywe nomxube owomileyo ludla ngokubandakanya iintlobo ngeentlobo zezongezo ezisebenzayo ukuphucula ukusebenza kwalo, ukunamathela, ukuqina, kunye nokuhambelana neemfuno ezahlukeneyo zokusetyenziswa. Ezi zongezo zidlala indima ebalulekileyo kudaka, kungekuphela nje ukuphucula ukusebenza kwalo ngokubanzi kodwa nokwandisa ukusetyenziswa kwalo kwiiprojekthi zokwakha. Oku kulandelayo yinkcazo emfutshane yezongezo eziqhelekileyo zodaka oluxutywe nomxube owomileyo kunye nemisebenzi yazo.
1. Ii-ether ze-cellulose (ezifana ne-HPMC kunye ne-MHEC)
I-Hydroxypropyl methylcellulose (HPMC)kwayei-methyl hydroxyethyl cellulose (MHEC)zezona zinto zisetyenziswa kakhulu ukugcina amanzi kunye neziqinisi, zibonelela ngokutyeba okugqwesileyo, ukugcina amanzi, kunye nokusebenza kakuhle. Zingacothisa ukulahleka kwamanzi, zonyuse ixesha lokuvula kwe-mortar, kwaye ziphucule ukuthambisa ukuze isetyenziswe kakuhle. Ii-cellulose ethers zikwaphucula iipropati ze-mortar zokulwa nokuqhekeka nokuqhekeka, okwenza ukuba zifaneleke ngakumbi kwizicelo ezifana nezincamathelisi zethayile, ii-plaster mortars, kunye nee-self-leveling mortars.
2. Umgubo wePolymer ophinda uchitheke (RDP)
I-RDPsisithako somgubo esisasazekayo ukuze senze ifilimu yepolymer. Umsebenzi waso ophambili kukuphucula ukunamathela, ukuguquguquka, ukumelana nokuqhekeka, kunye nokumelana namanzi kwe-mortar. Iphinda inyibilike ibe yi-emulsion emanzini, yenze isakhiwo esidibeneyo se-organic-inorganic ngesamente, iphucula ukumelana kwemozulu ye-mortar kunye namandla oomatshini. I-RDP isetyenziswa rhoqo kwi-adhesives zethayile, ii-mortars ezingangeni manzi, kunye nee-adhesive mortars ezikhusela udonga lwangaphandle.
3. I-Polycarboxylate Superplasticizer
Ii-polycarboxylate superplasticizers zizinto ezisebenza kakuhle kakhulu ekunciphiseni amanzi ezisetyenziswa kakhulu kwiimortars zanamhlanje ezomileyo, ikakhulu kwiimortars ezizilinganisayo kunye neemortars ezisebenzisa iplasta ephezulu. Iingenelo zazo ziquka ukuphucula kakhulu ukuhamba kwemortar, ukunciphisa ukusetyenziswa kwamanzi, kunye nokwandisa amandla kunye nokuqina. Xa kuthelekiswa nee-superplasticizers zemveli ezisekelwe kwi-naphthalene, ii-polycarboxylate superplasticizers zinobuhlobo ngakumbi nokusingqongileyo kwaye zifanelekile ukusetyenziswa kwizixhobo zokwakha eziluhlaza.
4. Ii-Defoamers kunye nee-Air-Entraining agents
Ii-defoamers zisusa ngempumelelo amaqamza aveliswa ngexesha lenkqubo yokuxuba i-mortar, zithintela iingxaki ezinje ngokugqobhoza nokuqhekeka, kwaye ziphucula umgangatho womphezulu. Kwelinye icala, ii-arhente zokungenisa umoya zinesiphumo esichaseneyo: zingenisa amaqamza amancinci, afanayo ukuphucula ukugcinwa kwamanzi kwi-mortar, ukumelana neqabaka, kunye nokusebenza kakuhle. Zingasetyenziswa ngokwahlukeneyo okanye zidityaniswe, kuxhomekeke kwiimfuno zemveliso.
5. Izinto eziqinisa amanzi kunye nezinto ezigcina amanzi (ezingeyo-cellulose)
Ukongeza kwi-cellulose ethers, ezinye ii-polymers zendalo okanye ezenziwe ngokwenziwa, ezifana ne-starch ethers, i-guar gum, kunye ne-polyvinyl alcohol, nazo zisetyenziswa rhoqo. Ezi zongezo zinokunceda ukuphucula i-mortar viscosity kunye nokugcinwa kwamanzi kwaye zihlala zidityaniswa ne-HPMC ukuze kufezekiswe iziphumo ezifanelekileyo zokusetyenziswa.
6. I-Retarder kunye ne-Hardening Accelerator
Izithinteli zokulungisa zandisa ukusebenza kwesamente kwaye zithintela ukuqina kwangethuba xa kushushu. Zihlala zisetyenziswa kwiiprojekthi zokwakha ezinkulu. Kwelinye icala, izithinteli zokuqinisa, zikhawulezisa ukuqina kwesamente kumaqondo obushushu aphantsi okanye phantsi kweemeko ezingxamisekileyo, ziphucula amandla okuqala kwaye zikhawulezise inkqubela phambili yeprojekthi.
7. Isithinteli-qhwa
I-antifreeze isetyenziswa kakhulu kwiindawo zokwakha zasebusika ukuthintela ukuba i-mortar ingaqandi kwaye ingaphumeleli kumaqondo obushushu aphantsi, igcine umswakama oqhelekileyo kunye nokunamathelana.
8. Izinto zokugxotha amanzi kunye nezinto zokuthintela amanzi
Isetyenziselwa ukuphucula ukumelana namanzi kwe-mortar kunye nokunciphisa ukuguquka kwe-alkali kunye nokungunda okubangelwa kukungena kwamanzi. Zisetyenziswa kakhulu kwi-mortar yangaphandle eludongeni, kwi-mortar engangeni manzi, nakwiindawo ezimanzi ezifana nezindlu zangasese kunye neekhitshi.
9. Ezinye izongezo ezisebenzayo
Ezi ziquka iifayibha ezithintela ukuqhekeka (ezifana neefayibha zepolypropylene), izixhasi zebhondi, izizalisi (ezifana nee-aggregates ezilula), ii-anti-slip agents, kunye neziguquli zombala. Ezi zongezo zinokukhethwa ngokuguquguquka kwaye zilinganiswe ngokwesicelo esithile se-mortar (ezifana ne-mortar yokulungisa, i-mortar yokuhombisa, kunye ne-mortar yenkqubo yokugquma).
Ukusebenza kodaka oluxutywe nomxube owomileyokuxhomekeke kakhulu ekudibaneni kunye nomlinganiselo wezongezo ezikhethiweyo. Iintlobo ezahlukeneyo ze-mortar, ezifana nezincamathelisi zethayile, ii-mortar ezizilinganisayo, ii-plaster zangaphandle zodonga, kunye nee-mortar ezingangeni manzi, zifuna izongezo ezahlukeneyo. Ukukhetha ngokufanelekileyo kunye nokwenza ngcono iintlobo zezongezo kunye needosi kubalulekile ekuqinisekiseni ukusebenza okuzinzileyo kunye nokusebenza kakuhle kwe-mortar eyomileyo.
