Izithasiselo ze-polymer zekhonkrithi yizinto ezisetshenziselwa ukuthuthukisa ukusebenza kokhonkolo. Bathuthukisa izakhiwo ezingokwenyama namakhemikhali kakhonkolo ngokwethula ama-polymers, ngaleyo ndlela bathuthukise amandla, ukuqina, ukusebenza, njll. Izithasiselo ze-polymer zingahlukaniswa zibe izinhlobo eziningana, okuhlanganisa ama-polymers ancibilika emanzini, ama-emulsion polymers, ama-polymers angu-powder, nama-polymers asebenzayo.
Izinhlobo zezithasiselo ze-polymer
Ama-polymers ancibilikayo emanzini: Lawa ma-polymers ngokuvamile akhona ngendlela yezixazululo ezinamanzi, ikakhulukazi kufaka phakathi i-polyvinyl alcohol (PVA), i-polyacrylamide (PAM), njll. ukungakwazi ukungena emanzini kanye nokumelana nokuqhekeka kukakhonkolo.
Ama-emulsion polymers: Ama-emulsion polymers awuhlobo lwama-polymers olwenziwa nge-emulsion polymerization, futhi ezivamile zihlanganisa ama-styrene-acrylate copolymers nama-ethylene-vinyl acetate copolymers. Lolu hlobo lwe-polymer lungathuthukisa izakhiwo zokubopha ukhonkolo futhi lwandise ukuqina nokumelana nokuqhekeka kukakhonkolo.
Ama-polymers angu-Powder: Ama-polymers angu-powdered angengezwa ngokuqondile emixubeni eyomile, njenge-ethylene-vinyl acetate powder (EVA), i-acrylate powder, njll. Lawa ma-polymers angu-powder angathuthukisa amandla acindezelayo kanye nokumelana nokuncibilika kokukhonkolo, futhi futhi asize ukunciphisa ukushwabana. kanye nokuqhekeka kukakhonkolo.
Ama-polymers asebenzayo: Lawa ma-polymers angasabela ngamakhemikhali nezingxenye zikasimende ukuze akhe into eyinhlanganisela ezinzile futhi ehlala isikhathi eside. Isibonelo, ama-epoxy resins, ama-polyurethanes, njll., angathuthukisa kakhulu ukumelana nokugqwala kwamakhemikhali, ukumelana nokuqina nokumelana nokugqoka kukakhonkolo.
Indlela yokusebenza yezithasiselo ze-polymer
Izithasiselo ze-polymer zithuthukisa ukusebenza kukakhonkolo ngemiphumela yomzimba namakhemikhali. Umphumela womzimba ngokuyinhloko ukugcwalisa ama-pores kusimende unamathisele, ukwandisa ukuminyana kukakhonkolo, nokunciphisa ukungena kwamanzi. Umphumela wamakhemikhali uwukwenza into eyinhlanganisela enwebekayo ngokusebenzisana phakathi kwe-polymer nemikhiqizo ye-cement hydration, ngaleyo ndlela kuthuthukiswe ukuqina nokuqina kukakhonkolo.
Thuthukisa ukusebenza kwebhondi: Izithasiselo ze-polymer zingakha ifilimu phakathi kwezinhlayiya zikasimende nama-aggregate, zithuthukise ukuhlangana phakathi kwakho kokubili, futhi ngaleyo ndlela zithuthukise amandla nokumelana nokuqhekeka kukakhonkolo.
Yehlisa ukuqhekeka kwe-shrinkage: Amanye ama-polymers angakhuphula ukuguquguquka kanye ne-ductility kakhonkolo, anciphise imifantu ebangelwa ukuncipha, futhi ngaleyo ndlela andise impilo yesevisi yezakhiwo zikakhonkolo.
Ukumelana nokugqwala kwamakhemikhali: Izithasiselo ze-polymer zingathuthukisa ukumelana nokugqwala kwamakhemikhali kakhonkolo, ikakhulukazi ezindaweni ezigqwalile njenge-asidi, i-alkali, nosawoti. Lawa ma-polymers angakwazi ukuvimbela ngempumelelo ukungena kwemithombo yezindaba ebolayo futhi avikele izakhiwo zekhonkrithi.
Thuthukisa ukumelana nokuncibilika kweqhwa: Ezindaweni ezibandayo, ukhonkolo uvame ukulinyazwa imijikelezo yokuqhwaza. Izithasiselo ze-polymer zingathuthukisa ngempumelelo ukumelana nokuncibilika kukakhonkolo ngokuthuthukisa ukuminyana kanye nokumelana nokuqhekeka.
Izindawo zokufaka izicelo
Izithasiselo ze-polymer zisetshenziswa kabanzi emikhakheni eminingi, kufaka phakathi:
Ubunjiniyela bokwakha: Ekwakhiweni kwezakhiwo zokuhlala nezohwebo, izithasiselo ze-polymer zivame ukusetshenziswa phansi, izindonga nezinye izingxenye ukuze kuthuthukiswe ukumelana nokuqhekeka nomphumela wokuhlobisa ukhonkolo.
Imigwaqo namabhuloho: Izithasiselo ze-polymer zisetshenziswa kabanzi ekwakhiweni kwemigwaqo namabhuloho ukuze kuthuthukiswe amandla acindezelayo nokuqina kokhonkolo, ngaleyo ndlela andise impilo yenkonzo yengqalasizinda.
Amaphrojekthi wokongiwa kwamanzi: Kumaphrojekthi okonga amanzi njengamadamu namadamu, izithasiselo ze-polymer zingathuthukisa ukungagxili kanye nokumelana nokugqwala kwamakhemikhali kakhonkolo, kuqinisekise ukuphepha nokuzinza kwephrojekthi.
Amaphrojekthi okulungisa: izithasiselo ze-polymer zivame ukusetshenziselwa ukulungisa nokuqinisa izakhiwo zekhonkrithi ezindala, ukuthuthukisa amandla azo esakhiwo nokuqina, nokugwema izindleko eziphezulu zokubhidliza nokwakhiwa kabusha.
Izithasiselo ze-polymer zekhonkrithi ziyingxenye ebalulekile yobuchwepheshe besimanje bokukhonkolo. Ngokwethula izinhlobo ezahlukene zama-polymers, izakhiwo ezahlukahlukene zikakhonkolo ziye zathuthukiswa kakhulu. Kungakhathaliseki ukuthi ekwakhiweni okusha noma ekulungiseni izakhiwo ezindala, ukusetshenziswa kwezithasiselo ze-polymer kunokubaluleka okusebenzayo okubalulekile. Ngokuthuthuka okuqhubekayo kobuchwepheshe, izithasiselo ze-polymer zesikhathi esizayo zizothuthukisa ukusebenza kukakhonkolo futhi zihlangabezane nezidingo zobunjiniyela ezidingeka kakhulu.
