Classification yeConcrete hardening agent uye simende inokurumidza-setting agent
Chii chinonzi a kongiri kuomesa mumiririri?
Concrete hardening agent ndiyo imwe yemhando dzakakura dzekusanganisa dzakashandiswa kare munhoroondo yebudiriro yezvakasanganiswa zvekongiri.. Kure kure, iyo indasitiri yakabudirira kugadzira zvakasiyana-siyana zvekongiri zvinoomesa, kusanganisira chloride uye sulfate. Pahwaro uhwu, tsvakurudzo yakawana zvakasiyana-siyana zvakasanganiswa kongiri admixtures, zvakadai seyekutanga-simba rekudzikisira mvura, yekutanga-simba mhando Antifreeze uye yekutanga simba yekupomba mumiririri, etc. Maererano nemakemikari ayo, yekutanga simba vamiririri vanogona kukamurwa kuita inorganic ekutanga simba vamiririri, organic ekutanga simba vamiririri uye composite admixtures.
Chii chinonzi simende chinokurumidza-setting agent?
Cement quick-setting agent musanganiswa wekongiri unogadzira simende sete uye inoomesa nekukurumidza. Simende inokurumidza-setting agent inomiririra chete 2% ku 3% yehuwandu hwesamende mukongiri. Zvakadaro, inogona kuita kongiri pakutanga yakaiswa mukati 5 maminitsi. Iyo accelerator inoisa mukati 12 maminetsi ekuzadzisa chinangwa chekugadzirisa kwekukurumidzira kana kukurumidza kuseta kongiri mu shaft. Cement inokurumidza-setting agent inonyanya kushandiswa mukongiri yakapfapfaidzwa uye yakapfapfaidzwa dhaka engineering. Inoshandiswa zvakanyanya muuinjiniya hwepasi, tunnel engineering, dyke slope kusimbisa, mvura plugging engineering, slip form kugadzira, kugadzirisa migwagwa, pfapfaidza anchor rutsigiro, etc. Kukurumidza kuomesa teknolojia. Cement inokurumidza kuseta agent inogona kupatsanurwa kuita poda simende inokurumidza-kuseta agent uye liquid simende inokurumidza-kuseta agent zvichienderana nemamiriro.; zvinoenderana neiyo alkali metal ion content, inogona kupatsanurwa kuita alkaline simende inokurumidza-kuseta ajenti uye yakaderera alkali simende inokurumidza kuseta ajenti uye alkali-isina simende inokurumidza-kuseta zvikamu zvitatu.; maererano nehukuru hwemakemikari zvinhu, inogona kukamurwa kuita aluminium oxide clinker pamwe necarbonate system, sulfoaluminate system, girazi remvura system uye yakaderera Alkali kana alkali-isina simende inokurumidza-kuisa mumiririri, etc. Besides, kune mishumo yekuti organic-inorganic composite simende inokurumidza-setting agents anoshandiswa kugadzira organic-inorganic yakasanganiswa simende inokurumidza-setting agents.. Simba rayo rekumanikidza rinowedzera uye rinogona kuderedza zvakanyanya huwandu hweguruva uye rebound panguva yekuvaka. Zvisinei, organic simende Kuunzwa kwechimbichimbi-inogadzirisa kazhinji kunokanganisa kukurumidza-kuseta mhedzisiro ye simende slurry..
Iyo meshini yekongiri yekuomesa agent uye simende inokurumidza-kuseta agent
Ingave iyo kongiri inoomesa agent kana simende inogadzirisa-inogadzirisa agent, mhando dzakasiyana, uye magadzirirwo echiito ndezvimwewo, uye yekutanga kusimbisa kana coagulation mhedzisiro yekongiri inoomesa ajenti kana simende inokurumidza kuseta ajenti inowanzoda kuitwa kuburikidza nemaitiro akawanda ekuita..
Ko kongiri inoomesa agent inoshanda sei?
Iyo mashandiro ekuita kwekongiri yekuomesa agent uye simende inokurumidza-kuisa agent yakafanana, ese ari maviri anowana simba rekutanga kana kukurumidza-kumisa mhedzisiro nekusimudzira hydration ye tricalcium aluminate uye tricalcium silicate muPortland simende.. Musiyano ndewekuti yekutanga-simba simba rekutanga-simba mumiriri rinowanzo kuratidzwa mune zvakawanda zvinhu.. Izvo hazvizongosimudzira iyo hydration ye tricalcium aluminate asi zvakare inosimudzira iyo hydration ye tricalcium silicate kuitira kuti kongiri inoomesa mumiriri inogona kushandiswa mukutanga nhanho ye hydration.. Ramba uchitamba basa rekutanga simba kuti usakanganise simba rekupedzisira rekongiri zvakanyanya.
Iyo simende inoshanda sei nekukurumidza-setting agent?
Iyo coagulation kukwidziridza simende inokurumidza-kuseta agent inowanzo kunangwa zvakanyanya. Kutevedzana kwemakemikari kuita kunoparadza kudzoreredza mhedzisiro yegypsum mu simenti uye nekukurumidza uye zvakanyanya kugadzira calcium aluminate hydrate., uye calcium sulfoaluminate hydrate Senge insoluble matter inopfupisa nguva yekupinza simende uye inosimudzira kukurumidza kuseta simende paste., asi panguva imwe cheteyo, zvinozongo tungamira kumatambudziko senge kusakwana kwesimba resamende dhaka (kana kongiri yakapfapfaidzwa) munguva inotevera.
Chinangwa chekongiri yekuomesa agent uye simende inokurumidza-kuseta agent
Pane misiyano yakakura pakati pekongiri yekuomesa ajenti uye simende inokurumidza-kuisa ajenti mumhando, performance, maitiro uye michina, uye mashandisirwo azvo akasiyanawo.
Mukuita kongiri, kuwedzera kongiri inoomesa mumiriri inogona kuwedzera zvakanyanya simba rekutanga rekongiri pasina kukanganisa simba rayo rekupedzisira, uye inogona kupfupisa zvinoshamisa nguva yekurapa. Naizvozvo, kutanga simba vamiririri anonyanya kushandiswa muchando kuvaka uye kongiri chikamu kugadzirwa. Mukuvaka kwechando, iyo kongiri ine yekutanga simba zvinodiwa kazhinji inoda kuwedzera yekutanga simba mumiriri kupfupisa kudhiza uye kurapa nguva, kukurumidzisa kufambira mberi kwekuvaka, uye zvinobudirira kudzivirira kukuvara kwechando, nokudaro zvinobudirira kuvandudza kushanda kwekuvaka uye kuchengetedza mari yekuvaka kongiri. Mukugadzirwa kwekongiri zvikamu, kushandiswa kwekongiri yekuomesa maajenti kwakatonyanya kuwanda kutambanudza simbi mbariro nokukurumidza sezvinobvira, mhanyisa formwork turnover uye pedestal utilization.
Nokuti nguva yekugadzika ye simenti inokurumidza-kugadzirisa agent ipfupi, hazvibviri kuve nechokwadi kuti kongiri yakanyatsosanganiswa uye inodururwa mukati menguva pfupi isati yatanga. Izvo hazvina kukodzera kune general formwork nzira yekudurura kongiri. Naizvozvo, accelerators haifanirwe kushandiswa mune general engineering. Cement inokurumidza-setting agent inonyanya kushandiswa kupfapfaidza kongiri kuvaka kana seyekukurumidza plugging zvinhu.
Cie-China.org ndiyo inotungamira furo kongiri yekuwedzera inopa inopa kongiri inopupuma mumiriri, superplasticizer,foam kongiri simba rekusimudzira kune lightweight kongiri, CLC inovhara. Kana uri kutsvaga kongiri kuomesa mumiririri ndapota inzwa wakasununguka taura nesu.
