1. Intshayelelo kunye nokuhlelwa kwesamente / udaka lokuzilinganisa
I-samente/udaka oluzilinganisayo luhlobo olunokubonelela ngomphezulu othe tyaba nogudileyo apho kungabekwa khona isiphelo sokugqibela (njengekhaphethi, umgangatho weplanga, njl. njl.). Iimfuno zayo eziphambili zokusebenza ziquka ukuqina ngokukhawuleza kunye nokunciphisa okuphantsi. Kukho iinkqubo zomgangatho ezahlukeneyo kwimarike ezifana nesamente-based, gypsum-based okanye imixube yazo. Kweli nqaku siza kugxila kwiinkqubo ezihambayo ezineempawu zokulinganisa. Umhlaba oqukuqelayo wehydraulic (ukuba usetyenziswa njengomaleko ogqumayo wokugqibela, ubizwa ngokuba yimathiriyeli yomphezulu; ukuba usetyenziswa njengomaleko ophakathi wotshintsho, ubizwa ngokuba yi-cushion material) zibizwa ngokuba yi: isamente-based self-leveling. umgangatho (umaleko womphezulu) kunye nesamente-based self-leveling floor (cushion layer) ).
2. Ukubunjwa kwezinto zemveliso kunye nomlinganiselo oqhelekileyo
I-Self-leveling Cement / mortar yi-hydraulically hardened composite material eyenziwe ngesamente njengesiseko sesiseko kwaye ihlanganiswe kakhulu kunye nezinye izinto eziguquliweyo. Nangona iifomula ezahlukeneyo ezikhoyo ngoku zahlukile kwaye zahlukile, kodwa ngokubanzi izixhobo
Ukwahlula kwiintlobo ezidweliswe ngezantsi, umgaqo uphantse ufana. Ubukhulu becala iqulunqwe zezi zahlulo zintandathu zilandelayo: (1) imathiriyeli yesamente exutyiweyo, (2) isihluzi seminerali, (3) isilawuli sokujiya, (4) isilungisi serheology, (5) icandelo lokuqinisa, (6) ukwakheka kwamanzi, oku kulandelayo imilinganiselo eqhelekileyo yabanye abavelisi.

(1) Inkqubo yayo yezinto ze-cementitious ngokuqhelekileyo iqulunqwe nge-samente ye-Portland eqhelekileyo (i-OPC), i-alumina cement ephezulu (CAC) kunye ne-calcium sulfate, ukwenzela ukubonelela nge-calcium eyaneleyo, i-aluminium kunye nesulfure ukwenza ilitye le-calcium vanadium. Oku kungenxa yokuba ukubunjwa kwelitye le-calcium vanadium kuneempawu ezintathu eziphambili, ezizezi (1) isantya sokubunjwa ngokukhawuleza, (2) umthamo wokubopha amanzi aphezulu, kunye (3) nokukwazi ukuncedisa ukucutheka, okuhambelana ngokupheleleyo neempawu ze-macroscopic ezizithandayo. -i-samente yokulinganisa / udaka kufuneka ibonelele ngokuFuna.
(2) Ukuhlelwa kwe-self-leveling ye-cement / mortar particles kufuna ukusetyenziswa kwe-coarser fillers (njengesanti ye-quartz) kunye nezihlunu ezicolekileyo (ezifana ne-conely ground calcium carbonate powder) ngokudibanisa ukufezekisa umphumo wokudibanisa.
(3) I-calcium sulfate eveliswe kwi-sement / mortar yokuzimela ngokuzimeleyo yi--hemihydrate gypsum (-CaSO4•½H2O) okanye i-anhydrite (CaSO4); banokukhupha i-sulfate radicals ngokukhawuleza ngokwaneleyo ngaphandle kokunyusa ukusetyenziswa kwamanzi. Umbuzo osoloko ubuzwa ukuba kutheni i--hemihydrate gypsum (ene-chemical composition efana ne--hemihydrate), efumaneka ngokukhawuleza kwaye ingabizi kakhulu kune--hemihydrate, ayikwazi ukusetyenziswa. Kodwa ingxaki kukuba umlinganiselo ophezulu we-void we--hemihydrate gypsum uya kwandisa kakhulu ukusetyenziswa kwamanzi, okuya kubangela ukuhla kwamandla omdaka olukhuni.
(4) I-powder ye-rubber e-dispersible iyona nxalenye ephambili ye-sement / mortar yokuzilinganisa. Inokuphucula ubumanzi, ukuxhathisa kwe-arbrasion surface, amandla okukhupha kunye namandla okuguquguquka. Ukongezelela, iyanciphisa i-modulus ye-elasticity, ngaloo ndlela inciphisa uxinzelelo lwangaphakathi lwenkqubo. Umgubo werabha ophinda uhlakazwe kufuneka ukwazi ukwenza iifilimu zepolymer ezomeleleyo. Iimveliso zesamente/udaka ezisebenza ngokuphezulu ziqulathe ukuya kuthi ga kwi-8% yomgubo werabha odispersible, kwaye ubukhulu becala zisamente yealumina ephezulu. Le mveliso iqinisekisa ukuqina ngokukhawuleza kunye namandla aphezulu kwangoko emva kweeyure ezingama-24, ngaloo ndlela ihlangabezana neemfuno zomsebenzi wokwakha wosuku olulandelayo, njengemisebenzi yokuhlaziya.
(5) I-Self-leveling cement / mortar idinga ukuseta i-accelerators (efana ne-lithium carbonate) ukufezekisa amandla okubeka i-samente ekuqaleni, kunye ne-retarders (njenge-tartaric acid) ukunciphisa isantya sokumisa i-gypsum.
(6) I-Superplasticizer (i-polycarboxylate superplasticizer) isebenza njengesinciphisi samanzi kwi-self-leveling cement / mortar kwaye ngaloo ndlela inikezela ukuhamba kunye nokusebenza komgangatho.
(7) I-defoamer ayikwazi ukunciphisa kuphela umxholo womoya kwaye iphucule amandla okugqibela, kodwa iphinde ifumane indawo efanayo, egudileyo kunye neqinile.
(8) Inani elincinci lokuzinza (elifana ne-cellulose ether) linokuthintela ukuhlukana komdaka kunye nokubunjwa kwesikhumba, ngaloo ndlela kubangele impembelelo embi kwiindawo zokugqibela zomhlaba. Umgubo werabha ophinda uhlakazwe uphucula ngakumbi iimpawu zokuqukuqela kwaye ube negalelo kumandla.
4. Iimfuno zomgangatho wemveliso kunye nobuchwepheshe obuphambili

Ulwelo luphawu olubalulekileyo olubonisa ukusebenza kwesamente/udaka lokuzilinganisa. Ngokuqhelekileyo, ukumanzi kungaphezulu kwe-210-260mm.
(2) Uzinzo oluludaka
Esi salathiso sisalathiso esibonisa uzinzo lwesamente/udaka lokuzilinganisa. Phalaza i-slurry edibeneyo kwi-plate yeglasi ebekwe ngokuthe tye, jonga emva kwemizuzu engama-20, akufanele kubekho ukopha okucacileyo, i-delamination, ulwahlulo, ukuxubha kunye nezinye izinto. Esi salathisi sinempembelelo enkulu kumphezulu kunye nokuqina kwezinto emva kokubumba.
(3) Amandla acinezelayo
Njengemathiriyeli ephantsi, esi salathisi kufuneka sihambelane nemigaqo yolwakhiwo lwemigangatho yesamente, imigangatho yesamente eqhelekileyo yasekhaya.
Amandla oxinzelelo omgangatho wokuqala kufuneka abe ngaphezulu kwe-15MPa, kwaye amandla oxinzelelo omgangatho wesamente wesamente angaphezulu kwe-20MPa.
(4) Amandla okuguquguquka
Amandla e-flexural ye-industrial self-leveling cement / mortar kufuneka ibe mkhulu kune-6Mpa.
(5) Ixesha le-Coagulation
Ngexesha lokumisela i-sement / mortar, emva kokuqinisekisa ukuba i-slurry ixutywe ngokulinganayo, qinisekisa ukuba ixesha lokusetyenziswa kwayo lingaphezu kwemizuzu engama-40, kwaye ukusebenza akuyi kuchaphazeleka.
(6) Ukuchaswa kwempembelelo
I-Self-leveling Cement / mortar kufuneka ikwazi ukumelana nefuthe lomzimba womntu kunye nezinto ezithuthwayo kwi-traffic eqhelekileyo, kwaye ukuchasana kwempembelelo yomhlaba kukhulu okanye kulingane ne-4 joules.
(7) Nxiba ukuxhathisa
Isamente/udaka oluzilinganisa ngokwalo njengemathiriyeli esemhlabeni kufuneka imelane netrafikhi eqhelekileyo emhlabeni. Ngenxa yomgangatho wayo omncinci wokulinganisa, xa isiseko somhlaba siqinile, amandla ayo okuthwala ubukhulu becala aphezu komhlaba, kungekhona kumthamo. Ngoko ke, ukumelana kwayo nokunxiba kubaluleke ngakumbi kunamandla oxinzelelo.
(8) Bond tensile amandla ukuya umaleko isiseko
Amandla okudibanisa phakathi kwe-sement / udaka oluzimeleyo kunye nomgangatho wesiseko uhambelana ngokuthe ngqo nokuba kuya kubakho ukugoba kunye nokuwa emva kokuba i-slurry iqinisiwe, enempembelelo enkulu ekukhoneni kwezinto. Kwinkqubo yokwakhiwa kwangempela, gcoba i-agent ye-interface yomhlaba ukuze ufikelele kwimeko efanelekileyo kakhulu yokwakhiwa kwezinto zokuzilinganisa. Amandla okuqina okuqina kwemathiriyeli yesamente yasekhaya ekwazi ukuzilinganisa ihlala ingaphezulu kwe-0.8MPa.
(9) Ukuxhathisa i-crack
Ukuchasana nokuqhekeka luphawu oluphambili lwesamente / udaka lokuzilinganisa, kwaye ubungakanani bayo buhambelana nokuba kukho iintanda, ukugoba, kunye nokuwa emva kokuba izinto zokuzilinganisa ziqina. Nokuba ungavavanya ngokuchanekileyo ukuxhathisa kokuqhekeka kwezixhobo zokuzilinganisa kunxulumene nokuba ungavavanya ngokuchanekileyo na impumelelo okanye ukusilela kwemveliso yemathiriyeli yokuziphakamisa.
5. Ukwakhiwa kwesamente/udaka lokuzilinganisa
(1) Unyango olusisiseko
Coca umaleko wesiseko ukususa uthuli oludadayo, amabala e-oyile kunye nezinye izinto ezingathandekiyo zokubopha. Ukuba kukho imingxuma emikhulu kwisiseko sesiseko, ukuzaliswa kunye nokulinganisa unyango luyafuneka.
(2) Unyango lwangaphandle
Faka iidyasi ezi-2 ze-arhente yojongano lomhlaba kumgangatho osezantsi ocociweyo.
(3) Ukwakhiwa komgangatho
Bala ubungakanani bezinto ezahlukeneyo ngokwesixa sezinto, umlinganiselo wamanzi-oluqilima (okanye umlinganiselo we-liquid-solid) kunye nommandla wokwakha, ugxobhoze ngokulinganayo nge-mixer, ugalele i-slurry enyakazelayo emhlabeni, kwaye ukhuhle ngobunono umququ.
(4) Ulondolozo
Inokugcinwa ngokweemfuno zezinto ezahlukeneyo zokuzilinganisa.
