I-Cellulose ether yama-Compounds azimele
Udaka oluzilinganisayo luwumkhiqizo wokuvikela imvelo wobuchwepheshe obuphezulu onokuqukethwe okuphezulu kobuchwepheshe kanye nezixhumanisi zobuchwepheshe eziyinkimbinkimbi. Luyimpahla exutshwe nempuphu eyomile eyakhiwe izithako eziningi, ezingasetshenziswa ngokuxuba amanzi endaweni. Ngemva kokusabalala kancane kwesikrufu, ungathola izinga eliphezulu lobuso besisekelo. Usimende ozilinganisayo unesivinini sokuqina ngokushesha. Ungahamba kuwo ngemva kwamahora angu-4-5, kanti ukwakhiwa kobuso (njengephansi lokhuni, ibhodi ledayimane, njll.) kungenziwa ngemva kwamahora angu-24. Ukwakhiwa okusheshayo nokulula akunakuqhathaniswa nokulinganisa ngesandla kwendabuko.
Usimende/udaka oluzilinganisayo luhlobo lobuso obuphansi obuyisicaba nobubushelelezi obungafakwa ngesendlalelo sokugcina (njengekhaphethi, phansi kokhuni, njll.). Izidingo zalo zokusebenza ezibalulekile zifaka phakathi ukuqina okusheshayo kanye nokuncipha okuphansi. Kunezinhlelo ezahlukene zephansi emakethe, njenge-simende, i-gypsum noma izingxube zazo.
Izakhiwo zobuchwepheshe eziyinhloko zesimende/udaka oluzilinganisayo
(1) Uketshezi
Ukugeleza kwamanzi kuyinkomba ebalulekile ekhombisa ukusebenza kwesimende/udaka oluzilinganisayo. Ngokuvamile, ukugeleza kwamanzi kungaphezu kuka-210 ~ 260mm.
(2) Ukuqina kodaka
Le index ibonisa ukuzinza kwesimende/udaka oluzilinganisayo. Thela i-slurry exubile epuletini lengilazi elibekwe ngokuvundlile, bese uqaphela ngemva kwemizuzu engama-20. Akufanele kube khona ukuphuma kwegazi okusobala, ukuhlukanisa, ukuhlukaniswa, noma ukuphenduka kwamabhamuza. Le index inomthelela omkhulu esimweni sobuso kanye nokuqina kwezinto ngemuva kokubumba.
(3) Amandla okucindezela
Njengezinto zokwakha phansi, lolu hlu kumele luhlangabezane nezimfuneko zokwakha phansi kwesamente. Iphansi elijwayelekile lesamente elingaphansi lidinga amandla okucindezela angu-15MPa noma ngaphezulu, futhi amandla okucindezela engqimba elingaphezulu lesamente elingaphansi lingu-20MPa noma ngaphezulu.
(4) Amandla okugobeka
Amandla okuguquguquka kwesimende/udaka oluzilinganisayo lwezimboni kufanele abe ngaphezu kuka-6Mpa.
(5) Isikhathi sokusetha
Ngesikhathi sokubeka usimende/udaka oluzilinganisayo, ngemva kokuqinisekisa ukuthi udaka luxubene ngokulinganayo, qiniseka ukuthi isikhathi sokusebenzisa singaphezu kwemizuzu engama-40, futhi ukusebenza kwalo ngeke kuthinteke.
(6) Ukumelana nomthelela
I-simende/udaka oluzilinganisayo kufanele lukwazi ukumelana nokushayisana okubangelwa yithrafikhi evamile nezinto ezithuthwayo, futhi ukumelana komthelela womhlaba kufanele kube kukhulu noma kulingane nama-joules ama-4.
(7) Ukumelana nokuguguleka
Usimende/udaka oluzilinganisa lusetshenziswa njengento engaphansi komhlaba futhi kumele lukwazi ukumelana nokuhamba komhlaba okuvamile. Ngenxa yokugeleza kwalo
Ingqimba eyisicaba incane, futhi uma isisekelo somhlabathi siqinile, amandla ayo okuthwala aphezu kobuso, hhayi phezu kobukhulu. Ngakho-ke, ukumelana kwayo nokuguguleka kubaluleke kakhulu kunamandla ayo okucindezela.
(8) Ukubopha amandla okunamathela kwesendlalelo sesisekelo
Amandla okubopha phakathi kwesamente/udaka oluzilinganisayo kanye nesendlalelo sesisekelo ahlobene ngqo nokuthi udaka luzogoqwa futhi luhlutshulwe yini ngemva kokuqina, okunomthelela omkhulu ekuqineni kwezinto. Enqubweni yokwakha yangempela, penta i-ejenti yokuxhumana komhlabathi ukuze ifinyelele esimweni esifaneleka kakhulu ekwakhiweni kwezinto ezizilinganisayo. Amandla okubopha izinto ezizilinganisayo phansi kwesamente yasekhaya ngokuvamile angaphezulu kuka-0.8MPa.
(9) Ukumelana nokuqhekeka
Ukumelana nokuqhekeka kuyisibonakaliso esibalulekile se-simende/udaka oluzilinganisayo, futhi ubukhulu balo buhlobene nokuthi izinto ezizilinganisayo zinemifantu, imigodi, kanye nokuchitheka ngemva kokuqina. Ukuhlolwa okufanele kokumelana nokuqhekeka kwezinto ezizilinganisayo kuhlobene nokuhlolwa okufanele kwempumelelo noma ukwehluleka kwezinto ezizilinganisayo.
