Ukuhambisana kwei-polycarboxylate superplasticizernezinye izixube

i-polycarboxylate superplasticizerfuthi ama-superplasticizers amaningi awakwazi ukuxutshwa futhi ahlanganiswe kunoma iyiphi ingxenye efana ne-naphthalene kanye ne-aliphatic superplasticizers. Isibonelo, umthelela ongemuhle ekugcinweni kokuwohloka kwepulasitiki mkhulu kakhulu lapho i-polycarboxylic acid nesinciphisi samanzi se-naphthalene kuhlanganiswa, futhi kufanele kuqashelwe ngokukhethekile. Lokhu kuphinde kwashukumisela abakhiqizi abaningi abanciphisa amanzi e-polycarboxylate ukuthi bahlanganise utshwala bomama obunemisebenzi ekhethekile ehlukahlukene njengokugcinwa kokuwohloka kanye namandla angaphambi kwesikhathi ukuze bavumelane nezidingo zokwakha ukhonkolo ezinkathini ezihlukene zonyaka, izinto zokwakha kanye nezilinganiso zokuxuba, futhi ekugcineni bathole imiphumela egculisayo. Kodwa-ke, ukuhlanganiswa kanye nokusetshenziswa okungokoqobo kotshwala kamama kudinga isikhathi, futhi uhlobo olulodwa lotshwala lukamama alukwazi ukuxazulula izinkinga eziningi ekusetshenzisweni kobunjiniyela kwama-superplasticizers. Kuyisithasiselo esidingekayo sokusetshenziswa kwei-polycarboxylate superplasticizer, futhi kubaluleke kakhulu ukuxazulula izinkinga zobuchwepheshe ezibhekene nesizinda sobunjiniyela ngokusebenzisa izici zotshwala kamama kanye nesimiso sokuhlanganiswa ngokomzimba sezinto ezincane. Kunconywa ukusebenzisa i-i-polycarboxylate superplasticizerngokuhlanganiswa nezinye izingxenye. Qinisekisa ukuthi uqinisekisa umphumela wokuhlanganisa kanye nomthelela wangempela kukhonkolo ngokusebenzisa izivivinyo, bese wahlulela ukuthi ngabe i-i-polycarboxylate superplasticizeringahlanganiswa nezinye izingxenye.

Inkinga yesikhutha sesitorejii-polycarboxylate superplasticizer

Lapho i-i-polycarboxylate superplasticizerkugcinwa enkathini yokushisa okuphezulu ehlobo, izenzakalo zesikhunta ezifana nokuphuma kwephunga elibi, ukugobhoza kwemiphongolo yokupakisha evaliwe, izindawo ezintantayo endaweni ewuketshezi ethangini lokugcina elivulekile, kanye nezinto ezintantayo ezimise okwestrip zivame ukwenzeka. Isizathu esiyinhloko ukuthi yonke inquboi-polycarboxylate superplasticizerkusukela ekukhiqizweni kuya ekusetshenzisweni nasekusetshenzisweni kugcinwa esimweni sebhaktheriya semvelo, kuyilapho izingxenye ezivame ukusetshenziswa ezibuyisela emuva njengoshukela nama-hydroxycarboxylates zihlinzeka ngesikhunta. Izakhamzimba ezinhle kakhulu, endaweni enezinga lokushisa elifanele kanye nomswakama kanye ne-pH engathathi hlangothi, inani lesikhunta landa kakhulu. Ngemva kokufa kwesikhunta, kusala inani elikhulu lezidumbu, okuyimbangela eyinhloko yesikhutha.i-polycarboxylate superplasticizer. Ngakho-ke, izithako ezisebenzayo ku-mildewedi-polycarboxylate superplasticizerazithinteki kakhulu, futhi ukusebenza kohlelo lokusebenza kuzinzile.

Isikhuntai-polycarboxylate superplasticizerinephunga elinamandla kanye negwebu eliningi ebusweni, elingahambisani nempilo yabasebenzi kanye nesilinganiso esinembile se-superplasticizer. Kuyadingeka ukuthatha izinyathelo zokuyicindezela. Phakathi kwazo, indlela ephumelela kakhulu ukuxuba ama-bactericides ukuze kuzuzwe umphumela we-bacteriostasis nokuvala inzalo. Ngesikhathi esifanayo, izindlela ezinjengokulungisa i-pH ye-ejenti yokunciphisa amanzi ukuze ingathathi hlangothi (pH≤3. noma i-pH>9.0) kanye nokushintsha uhlobo lwe-retarder nakho kungasetshenziswa.
