Chii chinonzi Wall putty?

Wall putty imhando yemidziyo inoshandiswa kupfavisa pamusoro pemadziro nekuzadza maburi nekuiisa kunze.Iyo simende-based powder inosanganiswa nemvura kuti iite paste-like consistency inogona kuiswa kumadziro.Chimwe chezvinhu zvakakosha zvemadziro putty is cellulose ether.

Cellulose ether ipolymer inonyungudika nemvura inotorwa kubva kucellulose chaiyo.Iyo inogadzirwa nekemikari inogadzirisa cellulose, inova inongoitika polima inowanikwa muchirimwa sero madziro.Cellulose ether inoshandiswa zvakanyanya muindasitiri yekuvaka seyakakora, stabilizer, binder, uye mumiriri wekuchengetedza mvura.Inoshandiswawo mukugadzirwa kwezvinhu zvakasiyana-siyana zvevatengi, sechikafu, zvizorwa, nemishonga.

Munyaya yemadziro putty, cellulose ether inoshanda seyakakora uye binder.Kana cellulose ether inowedzerwa kumadziro putty musanganiswa, inovandudza kushanda kwayo nekupa kugadzikana kwakatsetseka.Izvi zvinoita kuti zvive nyore kuisa putty kumadziro uye inova nechokwadi chekuti inonamatira zvakanaka kumusoro.Cellulose ether inobatsirawo mukudzivirira shrinkage uye kuputika kwemadziro putty mushure mekuoma.

Rimwe basa rakakosha re cellulose ether mumadziro putty kugona kwayo kuchengetedza mvura.Wall putty inoda kugara yakanyorova kweimwe nguva yenguva mushure mekushandisa kuti ive nechokwadi chekuti inomesa nemazvo uye inoita chisungo chakasimba nemadziro emadziro.Cellulose ether inobatsira mukuchengetedza mvura mumusanganiswa weputty, iyo inoderedza kuomeswa uye inovimbisa kuti putty inogadzika zvakanaka.

Hunhu uye kuita kwemadziro putty kunokonzerwa zvakanyanya nerudzi uye huwandu hweselulosi ether inoshandiswa.Kune akasiyana marudzi ecellulose ether anowanikwa pamusika, akadai sehydroxyethyl cellulose (HEC), methyl cellulose (MC), uye carboxymethyl cellulose (CMC).Rudzi rwega rwega rune zvimiro uye hunhu hwakasiyana, uye kusarudza iyo chaiyo mhando uye huwandu hwakakosha pakuona kunaka kwemadziro putty.

Muchidimbu, cellulose ether inoita basa rakakosha mukugadzirwa kwemadziro putty.Inopa iyo inodiwa thickening, kusunga, uye kuchengetedza mvura zvivakwa kune putty musanganiswa, iyo inovimbisa kushanda kwayo, inodzivirira shrinkage uye kuputika, uye inovimbisa kuomesa kwakakodzera uye kusungirirwa kumadziro emadziro.Kusarudza rudzi rwakakodzera uye huwandu hweselulosi ether yakakosha mukugadzira yakakwirira-yepamusoro madziro putty inosangana nezvinodiwa zveindasitiri yekuvaka.
