Hydroxypropyl methylcellulose (HPMC)imhando inokosha ye nonionic cellulose ether inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, anosanganisira kuvaka, mishonga, chikafu, uye zvizoro. Vanhu vazhinji vanonetseka nezvekushandiswa kweHPMC. Zvisinei, chiyero hachina kugadzika; chinosiyana zvichienderana neindasitiri, rudzi rwechigadzirwa, zvinodiwa pakushanda, uye fomura.
1. Mwero wekushandiswa kweHPMC muIndasitiri yeKuvaka
Indasitiri yekuvaka ndeimwe yemashandisirwo makuru eHPMC, kunyanya mudry-mix mortar, tile adhesive, putty powder, self-leveling mortar, uye thermal insulation mortar. HPMC inonyanya kubatsira kuchengetedza mvura, kukora, uye kuvandudza kushanda kwayo. Mwero wekushandiswa kwayo unowanzova pakati pe0.2% kusvika 0.8%, seizvi:
Kunamira mataira: Chiyero cheHPMC chinowanzova pakati pe0.3% ne0.5%, chinogadziriswa zvichienderana nekuwanda kwemvura yemataira, nzvimbo yekuvaka, uye giredhi rekunamira.
Putty yemadziro: Chipimo chakajairika i0.2% kusvika 0.4% kuti ive nechokwadi chekuti pamusoro peputty pakapfava, pasina kutsemuka. Dura rinozvienzanisa: Chipimo chinowanzova 0.1% kusvika 0.3%, uye kudzora viscosity kunodiwa kuti irambe ichiyerera.
Kudzivirira dhaka: Chiyero cheHPMC chinowanzova 0.3% kusvika 0.6% kuti mvura irambe ichichengetwa uye inamire, uye kudzivirira kutsemuka nekupwanyika.
Zvinhu zvinopesvedzera chiyero ichi zvinosanganisira giredhi rekupenya reHPMC (giredhi rakajairika rinosanganisira 40,000 mPa·s, 75,000 mPa·s, uye 100,000 mPa·s), kugadzirwa kwechigadzirwa, tembiricha yekushandisa, uye hunhu hwesimende.
2. Kushandiswa kweHPMC muIndasitiri yeMishonga
Muchikamu chemishonga, HPMC haiwanzo shandiswa sezvinhu zvemapiritsi ekuputira, maformula anoburitswa kwenguva refu, uye macapsule shells, asi inoda kuchena kwakanyanya uye kuchengetedzeka. Mashandisirwo Akajairika:
Kuputira piritsi: Kazhinji 2% kusvika 5% yehuremu hwepiritsi inoshandiswa kudzora mwero wekunyungudika uye kuvandudza chitarisiko.
Mapiritsi anobuda kwenguva refu: Huremu hweHPMC hunogona kusvika 10% kusvika 40%, zvichishanda sematrix zvinhu zvinononotsa kuburitswa kwemushonga. Makapisi asina chinhu: HPMC ndiyo inonyanya kushandiswa mumakapisi, ichidarika 50%.
3. Kushandiswa kweHPMC muIndasitiri yeChikafu
HPMC inoshandiswa sechinhu chinosimbisa, chinosanganisa, uye chinosimbisa muzvikafu, uye inowanzoshandiswa muzvikafu zvakabikwa, zvinwiwa, uye zvigadzirwa zvemukaka zvine mafuta mashoma. Mwero wekushandiswa unowanzova pakati pe0.1% kusvika 0.5%. Semuenzaniso:
Ice cream: Inenge 0.2% inowedzerwa kunatsiridza kuravira uye kudzivirira kuumbwa kweice crystal.
Zvikabikwa: Zvinosvika 0.3% zvakawedzerwa kuti zviwedzere kuchengetedza hunyoro uye kupfava.
4. Kushandiswa kweHPMC muindasitiri yemakemikari yezuva nezuva
HPMC inoshandiswa semushonga wekukora uye wekunyorovesa ganda mumashampoo, ma shower gels, uye zvigadzirwa zvekuchengetedza ganda, kazhinji pakushandiswa kwe0.3% kusvika 1.0%. Pakati peizvi:
Shampoo: 0.3% kusvika 0.6% yakawedzerwa kuti iwedzere kunaka kwetsinga dzemudumbu uye kunzwa kwadzo.
Mafuta ekuchengetedza ganda: Anenge 0.5% kusvika 1.0% anowedzerwa kuti awedzere kupararira uye kugadzira firimu rinonyorovesa ganda.
5. Zvinhu Zvikuru Zvinokanganisa Kushandiswa kweHPMC
Rudzi rweChigadzirwa: Masisitimu akasiyana ane zvinodiwa zvakasiyana, semuenzaniso, dhaka > chikafu.
Kusviba kweHPMC: Kusviba kwakanyanya HPMC inoda dosi shoma, asi ine mvura yakawanda inochengetedza.
Kupisa uye Nzvimbo: Kushandiswa kwemvura yakawanda kunoda kuti mvura irambe ichichengetwa zvakanyanya, izvo zvinoita kuti kushandiswa kweHPMC kuwedzere.
Kubatana Kwekugadzira: Kushandiswa kweHPMC kunogona kuderedzwa kana RDP kana starch ether ikashandiswa semubatsiri.
Hapana mwero wakatarwa wekushandiswa kweHPMC; inofanira kugadziriswa zvichienderana nezvinodiwa neindasitiri chaiyo uye maitiro ayo. Kazhinji, mwero wekushandiswa kweindasitiri yekuvaka i0.2%-0.6%, kune indasitiri yemishonga inogona kusvika pa40%, kune indasitiri yezvekudya ingave 0.1%-0.5%, uye kune zvigadzirwa zvemakemikari zvezuva nezuva i0.3%-1.0%.Kusarudza rudzi rweHPMC rwakakodzerauye mwero wekushandiswa kwemushonga hazvingobatsiri chete pakuita kwemushonga asiwo zvinodzora mitengo zvinobudirira.
