Tihlanganisi Letisebenta Kahle Letinciphisa Emanti: Kutfutfukisa Kusebenta Kwakhonkolo Ekwakhiweni Lokuluhlata
Tindzawo Letinkhulu Tesicelo
Tihlanganisi letisebenta kahle kakhulu letinciphisa emanti (njengetihlanganisi letisekelwe ku polycarboxylate) timelela luhlobo loluhamba embili kakhulu lwetintfo letinciphisa emanti letitfolakala emakethe. Tisebenta ngekwakha lucwencwe lwekusakateka etulu kwetinhlayiya tasimende, kuvikela kuhlanganiswa kwetinhlayiya tasimende ngaleyondlela kwenta ncono kugeleta kanye nekusebenta kwakhonkolo. Lomphumela wekusakateka awunciphisi kuphela kusetjentiswa kwemanti kepha uphindze ukhulise bukhulu kanye nemandla akhonkolo. Nawucatsanisa nekuhlanganiswa kwesintfu lokunciphisa emanti, tingucuko letisebenta kahle kakhulu tiniketa emazinga laphakeme ekunciphisa emanti (kuvame kuba ngu 25%-40%) kanye netidzingo letiphansi temthamo (kuvame kuba ngu 0.1%-0.3% welinani leliphelele letintfo tesimende), ngemtselela lomncane wemvelo.
Emaphrojekthi ekwakha, kusetjentiswa kwetihlanganisi letinciphisa emanti kungenta ncono kakhulu emandla ekucindzetela kanye nekumelana nemanti akhonkolo, kwelula imphilo yekusebenta yetakhiwo. Sibonelo, ekwakhiweni kwetakhiwo letiphakeme kanye nemabhuloho lamakhulu, tintfo letihlanganisiwe letinciphisa emanti letisebenta kahle kakhulu ticinisekisa kugeleta lokuhle kwakhonkolo ngaphansi kwetidzingo temandla lamakhulu, kwenta kutsi kube nemisebenti yekwakha. Ngekwengeta, tintfo letihlanganisiwe letinciphisa emanti tinganciphisa kukhopha kanye nekuhlukaniswa kukhonkolo, kwenta ncono kufana kwayo kanye nekungagucugucuki.
Emkhakheni wekwakha lokuluhlata, timphawu temvelo tekuhlanganiswa lokunciphisa emanti tibaluleke kakhulu. Kusetjentiswa kwetihlanganisi letisebenta kahle kakhulu letinciphisa emanti kungehlisa kusetjentiswa kwesimende, ngaleyondlela kwehlise kukhishwa kwekhabhoni. Ngetulu kwaloko, letintfo letihlanganisiwe tingakhulisa kucina kwakhonkolo, kunciphise tindleko tekunakekela kanye nekusebentisa tinsita tetakhiwo. Tihlanganisi letiningi letisebenta kahle kakhulu letinciphisa emanti nato titfole titifiketi temvelo temave emhlaba, letihambisana nemigomo yentfutfuko lesimeme yekwakha lokuluhlata.
Ngekutfutfuka lokuchubekako kwebuchwepheshe bekwakha, kusetjentiswa kwetinhlanganisela letinciphisa emanti nako kuyakhula. Sibonelo, kukhonkolo losebenta ngendlela lesetulu (HPC) kanye nakhonkolo loticinisako (SCC), tintfo letihlanganisiwe letinciphisa emanti tintfo letibalulekile leticinisekisa timphawu tekutilinganisa takhonkolo ngaphansi kwetimo letisetulu tekucina kanye nemandla. Ngekwengeta, tintfo letihlanganisiwe letinciphisa emanti tingasetjentiswa ngekuhlanganiswa naletinye tintfo letihlanganisiwe (njenge retarders kanye ne air-entraining agents) kwentela kuchubeka nekukhulisa timphahla takhonkolo.
Emaphrojekthi ekwakha, kusetjentiswa kwetihlanganisi letinciphisa emanti kungenta ncono kakhulu emandla ekucindzetela kanye nekumelana nemanti akhonkolo, kwelula imphilo yekusebenta yetakhiwo. Sibonelo, ekwakhiweni kwetakhiwo letiphakeme kanye nemabhuloho lamakhulu, tintfo letihlanganisiwe letinciphisa emanti letisebenta kahle kakhulu ticinisekisa kugeleta lokuhle kwakhonkolo ngaphansi kwetidzingo temandla lamakhulu, kwenta kutsi kube nemisebenti yekwakha.

Ngalokufishane
Tihlanganisi letinciphisa emanti tiyintfo lebalulekile yekungeta kubuchwepheshe bakhonkolo besimanje. Akugcini nje ngekutfutfukisa kusebenta kwakhonkolo kepha kuphindze futsi kusekele kwakha lokuluhlata kanye nekutfutfukiswa lokusimeme. Ngekuchubeka kwebuchwepheshe, ematfuba ekufaka sicelo sekuhlanganiswa lokunciphisa emanti atawuba makhulu kakhulu.
