Uri kunetseka kusarudza CMC grade chaiyo here? Dzidza kuti viscosity, level yekutsiva, uye kuchena zvinokanganisa sei mashandiro ezvigadzirwa zveceramics, chikafu, mishonga, nezvimwewo.

Ongorora kuti RDP inovandudza sei kuchengetedza mvura uye kudzivirira kutsemuka, zvichiita kuti putty yemadziro ishande zvakanaka uye yakavimbika.

HPMC neMHEC imhando mbiri dze cellulose ethers dzinoshandiswa mukuvaka nekugadzira, asi dzakasiyana sei? Chinyorwa chino chinoongorora musiyano mukuru uripo pakati peHydroxypropyl Methylcellulose (HPMC) neMethyl Hydroxyethyl Cellulose (MHEC), kusanganisira hunhu hwadzo hwemakemikari, kuchengetedza mvura, kugona kwayo kukora, uye mashandisirwo akanakisa.

Tsvaga kuti MHEC (Methyl Hydroxyethyl Cellulose) inowedzera sei simba rekubatanidza mataira uye inowedzera nguva yekuiswa kwenguva refu uye inoshanda. Dzidza mazano ekugadzira, mabhenefiti anotsigira sainzi, uye mhinduro dzematambudziko akajairika ekunamatira mataira.

Tsvaga kuti Hydroxyethyl Cellulose (HEC) inovandudza sei kunaka, kugadzikana, uye nyore kushandisa pendi dzakagadzirwa nemvura.

Chinyorwa chino chinoongorora basa reHPMC semunhu chinosimbisa, chinosimbisa, uye chinosimbisa mune zvakasiyana-siyana zvekudya, zvichiita kuti zvive nyore kushandisa, kuchengetedza hunyoro, uye kushanda zvakanaka kwechigadzirwa. Dzidza nezvemabhenefiti acho, mashandisirwo acho, uye kutevedzera mitemo yekuchengetedza chikafu.

Tsvaga maitiro matsva ekugadzira HPMC—kubva pakuburitsa cellulose yechisikigo uye etherification kusvika pakuomesa kwepamusoro uye kudzora mhando—zvichiratidza kuvandudzwa kwemaitiro matsva uye zvirongwa zvekuchengetedza nharaunda mukugadzira HPMC.

Ongorora kuti Hydroxypropyl Methyl Cellulose (HPMC) inovandudza sei thermal insulation mortar nekuvandudza kuchengetedza mvura, kushanda zvakanaka, uye kunamira. Dzidza nezvemabhenefiti ayo makuru uye mashandisirwo ayo mukuvaka.

Dzidza kuti HPMC inovandudza sei mashandiro edhaka rakasanganiswa negypsum nesimende nekuvandudza mashandiro aro, kuchengetedza mvura, uye kunamira. Tsvaga nzira dzakanakisisa uye mabhenefiti ekubudirira kwekuvaka kwakanaka.
