Lik'hemik'hale tse kotsi li bolela lik'hemik'hale tse chefo haholo le lik'hemik'hale tse ling tse chefo, tse senyang, tse phatlohang, tse ka chang, tse tšehetsang mollo le tse kotsi 'meleng oa motho, lisebelisoa le tikoloho.
Lisebelisoa tse phahameng tsa ho fokotsa metsi bakeng sa konkreite haholo-holo li kenyelletsa letoto la naphthalene, letoto la melamine le li-agent tse fokotsang metsi tse kopantsoeng ho tsona, tseo lihlopha tsa naphthalene e leng tsona tse ka sehloohong, tse ikarabellang bakeng sa 67%. Naphthalene letoto la melamine ha se lik'hemik'hale tse kotsi. Ka hona, superplasticizer ea konkreite ha se ea sehlopha sa lik'hemik'hale tse kotsi.
Motsoako o ka fokotsang haholo molumo oa metsi a kopanyang tlas'a boemo ba hore ho putlama ha konkreite ha e le hantle ho tšoana ho bitsoa moemeli oa ho fokotsa metsi o sebetsang hantle haholo.
Sekhahla sa phokotso ea metsi ea sesebelisoa sa ho fokotsa metsi se sebetsang hantle haholo se ka fihla ho feta 20%. Haholo-holo e entsoe ka letoto la naphthalene, letoto la melamine le li-agent tse fokotsang metsi tse kopantsoeng ho tsona, tseo lihlopha tsa naphthalene e leng tsona tse ka sehloohong, tse etsang 67%. Haholo-holo Chaena, boholo ba li-superplasticizers ke li-superplasticizers tsa naphthalene tse nang le naphthalene e le eona ntho e ka sehloohong e tala. Naphthalene series superplasticizer e ka aroloa ka lihlahisoa tse phahameng tsa mahloriso (Na2SO4 content <3%), lihlahisoa tsa mahloriso tse mahareng (Na2SO4 content 3% ~ 10%) le lihlahisoa tse tlaase tsa mahloriso (Na2SO4 content>10%) ho ea ka litaba tsa Na2SO4 lihlahisoa tsa eona. . Boholo ba naphthalene letoto la li-superplasticizer synthesis limela li na le bokhoni ba ho laola litaba tsa Na2SO4 ka tlase ho 3%, 'me likhoebo tse ling tse tsoetseng pele li ka li laola ka tlase ho 0.4%.
Sebaka sa ts'ebeliso:
E sebetsa ho konkreite e matlafalitsoeng esale pele le ho lahloa meahong e fapaneng ea liindasteri le ea lehae, paballo ea metsi, lipalangoang, likoung, masepala le merero e meng.
E sebetsa ho konkreite e matla, e phahameng-ea matla le e bohareng, hammoho le konkreite e hlokang matla a pele, ho hanyetsa serame ka mokhoa o itekanetseng le metsi a mangata.
Likarolo tsa konkreite tse entsoeng esale pele tse loketseng ts'ebetso ea ho folisa mouoane.
E loketse ho etsa likarolo tsa ho fokotsa le ho matlafatsa metsi (ke hore masterbatch) ea metsoako e mengata e fapaneng.
Ha se ea. Lik'hemik'hale tse kotsi ke lisebelisoa tse phatlohang. Leha ho le joalo, superplasticizer ea konkreite e akaretsang ha e na likarolo tse phatlohang le tse phatlohang, kahoo superplasticizer ea konkreite ha se ea lik'hemik'hale tse kotsi.
