Ama-ejenti ahlanganisiwe asuselwa ku-gypsum abucayi embonini yezokwakha yokuhlinzeka ngokuqeda okubushelelezi ezindongeni nophahla, ukugcwalisa izikhala, nokuqinisekisa indawo ehlala isikhathi eside, ebusayo. Ukusebenza kanye nezici zalawa ma-ejenti zithonywa kakhulu yizithasiselo ezahlukahlukene, eziguqula izakhiwo ezifana nokusebenza, ukunamathela, isikhathi sokusoma namandla, namandla okugcina. Phakathi kwalezi zengezo, isitashi ether sithole ukunakwa ngezakhiwo nezinzuzo ezihlukile.
Isitashi i-ether
I-Starch Ether ngumkhiqizo wesitashi oguquliwe ovame ukuthathwa kwimithombo yemvelo efana nommbila, amazambane, noma i-tapioca. Ithola ukuguqulwa kwamakhemikhali ukuthuthukisa izici zayo zokusebenza, okwenza kube lula ukusetshenziswa ezintweni zokwakha ezifana ne-Gypsum Coaling Agents.
Izinzuzo zeStarch Ether
Ukusebenza nokugcinwa kwamanzi: isitashi i-ether ithuthukisa ukusebenza kwezindawo zokuhlangana ezenzelwe ama-gypsum. Kuthuthukisa i-viscosity kanye nomthamo wokugcina amanzi, ukuvimba le ngxube ekumisweni ngokushesha okukhulu futhi okuvumela isikhathi esingeziwe sokusebenza. Le mpahla inenzuzo ikakhulukazi ezikhathini ezishisayo nezomile lapho ukomisa okusheshayo kungaba yinkinga.
Ukuphikiswa kwe-SAG okuthuthukisiwe: ngokwandisa i-viscosity, isitashi i-Ether kusiza ekugcinweni kokuqina kwengxenye ehlanganayo, kunciphisa ukugcwala noma ukushelela kokuqukethwe lapho kufakwa endaweni ebheke phezulu.
Ukuqedwa okubushelelezi: Ukuba khona kwe-Starch Ether kunomthelela oxukwini olubushelelezi nolwengeziwe, okuholela ekuqedeni okuhle okulula ukupenda nokupenda.
I-Eco-Friendly: Itholakala emithonjeni yemvelo, isitashi i-Ether iyi-biodegradable futhi inobungane bemvelo, ivumelana nesidingo esandayo sezinto zokwakha ezizinzile.
Ukulinganiselwa kwe-Starch Ether
Izindleko: Ngokuya ngomthombo nangezinga lokuguqulwa, isitashi i-ether ingabiza kakhulu kunezinye izengezo, ngokungezelela izindleko zizonke zekhilodi ehlanganayo.
Ukungaguquguquki: Ukusebenza kweStarch ETHER kungahluka ngokuya ngomthombo wayo kanye nokuguqulwa okuthile kwamakhemikhali okusetshenzisiwe, okuholela ekungatholelekeni kwekhwalithi yomkhiqizo.
Ezinye izengezo ezijwayelekile
I-Cellulose Afers
I-Cellulose Tashers, enjenge-methylcellose (MC) kanye ne-hydroxypropyll methylcellulose (HPMC), isetshenziswa kabanzi kwizinhlanganisela ezihlangene ze-gypsum zokuqothula, ukugcinwa kwamanzi, nezindawo ezibophayo.
Ukujikeleza nokugcinwa kwamanzi: okufana ne-starch ether, abaphikisi be-cellulose bathuthukisa ukubonwa nokugcinwa kwamanzi kwendawo. Lokhu kuqinisekisa ukusebenziseka okuhle futhi kuvimbela ukoma ngaphambi kwesikhathi, ukuthuthukisa kalula uhlelo lokusebenza.
Ukunamathela kanye nokubumbana: Abathengisi beCellulose bathuthukisa izakhiwo ezinamathela zendawo ehlanganayo, baqinisekisa ukubopha okungcono ku-substrates kanye nokuhlangana ngaphakathi kwengxube.
Ukuzilwa Kwezinga lokushisa: Lezi izengezo zihlinzeka ngokusebenza okungaguquki kuwo wonke amazinga okushisa, okwenza baguquguquke ngezimo ezahlukahlukene zesimo sezulu.
I-Biodegradeabilibility: Njenge-Starch Heather, ama-Cellulose Afers ayi-biodegradable futhi enobungane bemvelo.
Ama-polymer polymer polymer (ama-rdps)
Ama-polymer polymer polymer, njengalezo ezisuselwa ku-vinyl acetate ethylene (VAE) COPOLYERMERS, zengezwa ukuthuthukisa ukuguquguquka nokuqina kwama-gypsum ahlanganile abenzeli.
Ukuguquguquka okuthuthukisiwe: I-RDPS Thuthukisa ukuguquguquka kwe-Conting Compound, ukunciphisa ubungozi bokuqhekeka kanye nokufiphaza ngokuhamba kwesikhathi, okubaluleke kakhulu ezindaweni ezibheke phambili ekuhambeni okuhlelekile.
Adhesion: Lawa mapondo athuthukisa kakhulu izakhiwo ezinamathela, aqinisekise ukubopha okuqinile ezinhlobonhlobo zezigatshana ezifaka phakathi okunzima njengodaka oludala noma indawo edwetshwe.
Ukumelana Amanzi: I-RDPS Thuthukisa ukumelana kwamanzi kwe-Compound, okwenza kube nzima kakhulu ezindaweni ezinomswakama.
Retaarders kanye namashevu
Ama-ejenti ahlanganisiwe asuselwa ku-gypsum angafaka futhi ama-retardars noma ama-accelerator ukulawula isikhathi sokubeka ingxube.
Ama-retaarders: izengezo njenge-citric acid noma i-tartaric acid zisetshenziselwa ukwehlisa isikhathi sokusetha, ukuhlinzeka isikhathi esithe xaxa samaphrojekthi amakhulu noma izinhlelo eziyinkimbinkimbi.
Ama-accelerator: Ngakolunye uhlangothi, amakhompiyutha afana ne-potassium sulfate angasetshenziswa ukusheshisa isikhathi sokusetha, okuwusizo kumaphrojekthi wokwakha asheshayo adinga ukuguquguquka okusheshayo okudinga imali esheshayo edinga ukuba kube nokungena ngokushesha.
Ukuqhathanisa Ukuqhathanisa
Uma uqhathanisa isitashi ether nge-cellulose izithathekisa, ama-rdps nezinye izithasiselo, kuvela amaphuzu athile asemqoka:
Ukusebenza ekusebenzeni nasekugcinweni kwamanzi: Kokubili i-Starch ether kanye ne-cellulose i-excer excel ekuthuthukiseni ukukhiqizwa nokugcinwa kwamanzi. Kodwa-ke, i-Starch Ether ingahlinzeka ngokuqedwa okubushelelezi ngenxa yesakhiwo sayo esiyingqayizivele samakhemikhali.
Izindleko kanye nokutholakala: Abathengisi beCellulose kanye nama-RDPs ngokuvamile batholakala kabanzi futhi bangabiza kakhulu kune-starch ether, okwenza bavame ukusetshenziswa kakhulu embonini. Kodwa-ke, izinzuzo zemvelo ze-starch ether zingacacisa izindleko eziphakeme kumaphrojekthi we-eco-akwazi.
Ukuvumelana nezimo nokuqina: ama-RDPs anikela ngentuthuko ephakeme ekuguqulekeni nasekudakeni isikhathi eside ngokuqhathaniswa ne-starch ether kanye ne-cellulose afer, okwenza babaluleke kakhulu kuzinhlelo zokusebenza lapho inhlangano yesakhiwo ibalulekile.
Ukubeka isikhathi sokulawula: Isitashi ether asithobeli kakhulu isikhathi sokusetha, kanti ama-retaarders athile kanye nama-accelerator acugela amaphrojekthi anezingqinamba zesikhathi esiqinile.
Umthelela Wezemvelo: Kokubili i-Starch Ether kanye ne-cellulose afer kuyinto bioderhradable futhi enobungane, ukuvumelana nemikhuba yokwakha esimeme. I-RDPS, ngenkathi ithuthukisa ukusebenza, anhlobo futhi ingaba nesinyathelo esiphakeme semvelo.
Endaweni ye-Gypsum asungula ama-ejenti, ukukhethwa kwezithambiso kudlala indima ebaluleke kakhulu ekunqumeni izici zokusebenza komkhiqizo wokugcina. I-Starch Ether inikela ngezinzuzo eziphawuleka ekusebenzeni, ukugcinwa kwamanzi, kanye nobungane bezemvelo, okwenza kube yinto ebalulekile naphezu kwezindleko zayo eziphakeme kanye nokwehluka. AbakwaCellulose Abather bahlinzeka ngezinzuzo ezifanayo futhi babiza kakhulu futhi bengaguquki. I-RDPs ithuthukisa ukuguquguquka nokuqina, okubalulekile ekwakhekeni okuthambekele ekuhambeni. Okokugcina, ama-retaarders nama-accelerator asemqoka ngokulawula izikhathi zokubeka.
