Uhlolojikelele lwe-Self-Leveling Compound

Ikhompiyutha yokuzilinganisa, izinto ezibalulekile kubunjiniyela besimanje bokwakha phansi, imvamisa yakhiwe kusuka kusimende wase-Portland, ama-aggregate amahle, ama-polymers asebenzayo, nezithasiselo ezikhethekile. Isakhiwo sazo esiyingqayizivele sokuzilinganisa sivela odaka olumanzi oluphezulu olwakhiwe ngemva kokuxubana, olungaleveli ngokuzenzakalelayo ngaphansi kwamandla adonsela phansi ukuze kwakhe izisekelo ezibushelelezi ezinogqinsi olusuka ku-3mm kuya ku-50mm.

Izicelo ezijwayelekile zifaka izitshalo zezimboni (isb., izitezi ezinemba okuphezulu ezindaweni zokusebenzela zokukhiqiza izimoto), izindawo zezentengiselwano (isb, indawo enkulu engagugi ezitolo ezinkulu eziwuchungechunge), kanye namaphrojekthi okuhlala asezingeni eliphezulu (isb., izendlalelo zokulinganisa zamasistimu okushisa angaphansi).

Izinzuzo Zokwakha

Uma kuqhathaniswa nezinqubo zokulinganisa udaka lwendabuko, izinhlanganisela zokuzilinganisa zithuthukisa ukusebenza kahle kokwakhiwa ngo-40% -60%. Isici sabo sokuphulukisa ngokushesha sifinyeza kakhulu ubude bephrojekthi, sibenze bafaneleke "ukwakhiwa kwasebusuku—ukulethwa kosuku olulandelayo" kumaphrojekthi wokulungisa.

Kungani usebenzise i-HPMC ku-Self-Leveling Compound? Injani iPerformance?

a. Umthetho Wokugcina Amanzi

Ama-molecule e-HPMC akhangisa amanzi ngamabhondi e-hydrogen, akhe inethiwekhi enezinhlangothi ezintathu ezikhulisa ukugcinwa kwamanzi odaka kuze kube ngaphezu kuka-90% (uma kuqhathaniswa nama-75% ngaphandle kwe-HPMC). Ezindaweni ezinezinga lokushisa eliphezulu (>30°C), ukukhetha i-HPMC enezinga lokushisa le-gelation ≥65°C kulibazisa ukuhwamuka kwamanzi, kuvimbele ukulahlekelwa amandla ngenxa yokunganele kukasimende ukugeleza kwamanzi.

b. Ukuthuthukiswa Kwezakhiwo Ze-Rheological

• Ukulawula Ukugeleza: I-HPMC ye-viscosity ephansi (isb, 400Mpas) inciphisa ukucindezeleka kwesivuno, ifinyelela amanani okugeleza okuqala ka-180-220mm ngokuzilinganisa kongqimba oluncane (3-5mm); izinhlobo ze-viscosity ephezulu (isb., 15000Mpas) zithuthukisa i-thixotropy, ivimbela ukuhlangana kwe-sedimentation ekwakhiweni kongqimba obukhulu (10-50mm) ukuze kuqinisekiswe ukuminyana okufanayo.

• Umphumela we-Synergistic: Uma kuhlanganiswa nezinciphisi zamanzi ze-polycarboxylate, i-HPMC ivimbela ukuhlukaniswa. Esinciphisi samanzi esingu-0.3% kanye ne-0.12% HPMC, ukulahleka kokugeleza kwemizuzu engama-30 ≤10%, kuhlangabezana nezidingo zokugeleza ezincike esikhathini zokuzilinganisa.

c. Ukuncipha kanye Nokuvimbela Ukuqhekeka

Ngokubambezela ukusikwa kwe-hydration (ukwandisa isikhathi sokuqala sokumisa ngemizuzu eyi-15-30), i-HPMC yehlisa ingcindezi yokuncipha kwangaphambi kwesikhathi ngama-30%.Ezivivinyweni zokomisa ukuncipha, udaka olune-HPMC lukhombisa izinga lokuncipha lezinsuku ezingama-28 elingu-0.018%, eliphansi kakhulu kuno-0.035% kumasampula angewona awe-HPMC, okunciphisa ngempumelelo ukuqhekeka okuncane.

Ungayikhetha kanjani i-HPMC efanele ukuze ihambisane neSimo Self-Leveling Compound Constructions?

I-HPMC yezinga lezimboni ihlukaniswa nge-viscosity yesisombululo sayo samanzi esingu-2% sibe yi-low-viscosity(30000Mpas), ezihlinzeka ngezidingo ezahlukene zokwakha.

Amamethrikhi angukhiyeYezokwakha EzihlukeneIsimo

Isibonelo Sokwakha (Ukuzilinganisa Okusekelwe eGypsum):Ukubunjwa okuyisisekelo: i-α-hemihydrate gypsum 60%, i-calcium carbonate 30%, isihlabathi se-quartz (80-120 mesh) 10%; Izithasiselo: I-HPMC (20000mPa·s, 0.18%), i-retarder (tartaric acid, 0.05%), isinciphisi samanzi (i-melamine-based, 0.3%.(Lokhu okokubhekisela kwakho kuphela) 

Isiphetho

Njengesengezo esisebenzayo kumakhompiyutha wokuzilinganisa,I-HPMCkunomthelela ekusebenzeni kwezinto ezibonakalayo kukho konke ukulungiselela, ukwakha, nokuphila kwesevisi. Ngokukhula kwezidingo zokunemba kwe-flooring ekwakheni izimboni,I-HPMCukukhetha kanye nobuchwepheshe bokusebenzisa buzocwengwa futhi buhlakaniphe kakhulu.
