Apa peran hydroxypropyl methylcellulose ing beton busa

Suda dhuwur saka blok test ing cetakan sawise ngecor ciri efek hydroxypropyl methylcellulose ing stabilitas volume konkrit foamed. Bisa dideleng yen dosis 0,05% hydroxypropyl methylcellulose minangka dosis becik, lan nalika dosis hydroxypropylmethylcellulose 0,05%, dhuwur reduksi saya tambah. Analisis nuduhake yen nalika hydroxypropyl methylcellulose cocok, bisa nyuda volume shrinkage saka hardened awak nalika nambah fluidity saka slurry. Sajrone proses hardening slurry, banyu terus ilang. Umpluk internal uga terus-terusan disillusioned, lan shortening saka awak hardened ora bisa dihindari. Iki nyebabake volume awak hardened dadi ora stabil, lan campuran hydroxypropyl methylcellulose ora mung nyedhiyakake awak hardened Ora mung nduweni efek penylametan banyu sing apik, nanging uga stabil lan hardens umpluk pisanan liwat karakteristik hardening slurry lan hydroxypropyl. hardening film methylcellulose ing wektu sing padha, supaya bisa muter efek stabil umpluk apik lan nyuda shrinkage saka hardened volume awak.

Stabilisasi busa tambahan

Minangka jumlah hidroksipropil metilselulosa tambah dadi 0,5%, slump rada mudhun. Data nuduhake yen nalika isi hydroxypropyl methylcellulose ora ngluwihi 0,05%, Kajaba saka hydroxypropyl methylcellulose bisa Ngartekno nambah fluidity lan viskositas saka slurry konkrit foamed. Sawise hydroxypropyl methylcellulose dibubarake, film elastis fleksibel sing lembab dibentuk ing antarane partikel fase padat lan gelembung fase gas, sing nduweni efek Gamelan sing apik sajrone proses pencampuran. Slurry gratis lan seragam "bal", sing èfèktif mbenakake fluidity saka slurry anyar dicampur: nanging yen jumlah hydroxypropyl methylcellulose ngluwihi 0,5%, slurry bakal dadi banget kenthel lan fluidity bakal suda banget. Nanging, 0,05% hydroxypropyl methylcellulose ora mung njamin slump, nanging uga stabil umpluk udhara, kang becik kanggo nambah wong.
