Hydroxypropyl methylcellulose (HPMC muchidimbu) imhando yakakosha ye ether, inova polymer isinganyunguduke mumvura, uye inoshandiswa zvakanyanya mukudya, mishonga, indasitiri yemakemikari yezuva nezuva, coating, polymerization reaction uye kuvaka se dispersion suspension, thickening, emulsifying, stabilizing uye glues, nezvimwewo, uye pane musiyano mukuru mumusika wemuno.
Hydroxypropyl methylcellulose inoshandiswa zvakanyanya muindasitiri yekuvaka sechinhu chinogadzira mafirimu, chinosunga, chinoparadzira, chinosimbisa, chinosimbisa mvura, nezvimwewo, uye chave chigadzirwa chine mukurumbira chakakwezva kutariswa kubva payakatanga kushandiswa pamutsetse uyu.

Zita rakazara rechirungu: Hydroxypropyl Methyl Cellulose Chidimbu cheChirungu: HPMC
Nekuti HPMC ine hunhu hwakanaka hwakadai sekukora, emulsification, film forming, protective colloid, moisture retention, adhesion, enzyme resistance uye metabolic inertness, inoshandiswa zvakanyanya mukuputira, polymerization reactions, zvinhu zvekuvaka, kugadzira mafuta, machira, chikafu, mishonga, Daily-use ceramics, electronic devices nembeu dzekurima nedzimwe nzvimbo.
zvinhu zvekuvaka
Muzvinhu zvekuvaka, HPMC kana MC inowanzo wedzerwa kusimende, dhaka, uye dhaka kuti ivandudze hunhu hwekuvaka uye hwekuchengetedza mvura.
Inogona kushandiswa se:
1). Chinhu chinonamira uye chinobata madziro chetepi inonamira yakagadzirwa negypsum;
2). Kubatanidzwa kwezvidhinha, mataira nenheyo zvakagadzirwa nesimende;
3). Stucco yakagadzirwa neplasterboard;
4). Purasi yekuvaka yakagadzirwa nesimende;
5). Muchimiro chemushonga wekubvisa pendi nependi.

Indasitiri yekupenda
Muindasitiri yekupenda, HPMC inonyanya kushandiswa muzvikamu zvependi yelatex neresin inonyungudika mumvura sechinhu chinoumba firimu, chinosimbisa, chinosimbisa uye chinosimbisa.
Kugadziriswa kwePVC
Nzvimbo inonyanya kushandiswa kwezvigadzirwa zveHPMC munyika yangu ndeye suspension polymerization yevinyl chloride. Mu suspension polymerization yevinyl chloride, nzira yekupararira inokanganisa zvakananga mhando yePVC resin yechigadzirwa uye kugadziriswa kwayo uye zvigadzirwa; inogona kuvandudza kugadzikana kwekupisa kweresin uye kudzora kugoverwa kwehukuru hwezvidimbu (ndiko kuti, kugadzirisa density yePVC). Huwandu hweHPMC hunosvika 0.025% ~ 0.03 yePVC output%.
Resin yePVC yakagadzirwa neHPMC yepamusoro-soro, pamusoro pekuona kuti mashandiro ayo anoenderana nezvinodiwa nenyika, inewo hunhu hwakanaka hwemuviri, hunhu hwakanaka hwezvimedu uye hunhu hwakanaka hwe rheological hwakanyungudika.
mamwe maindasitiri
Mamwe maindasitiri anosanganisira zvizoro, kugadzira mafuta, sipo, zviumbwa zvemumba nezvimwe.
inonyungudika mumvura
HPMC ndeimwe yemapolymer anonyungudika mumvura, uye kunyungudika kwayo mumvura kunoenderana nehuwandu hweboka remethoxyl. Kana huwandu hweboka remethoxyl hwakaderera, inogona kunyungudika mualkali yakasimba uye haina nzvimbo yekupisa ye thermodynamic. Nekuwedzera kwehuwandu hwemethoxyl, inonyanya kubatwa nekuzvimba kwemvura uye inonyungudika mualkali yakanyungudika uye alkali isina simba. Kana huwandu hwemethoxyl huri >38C, inogona kunyungudika mumvura, uye inogonawo kunyungudika muhalogenated hydrocarbons. Kana periodic acid ikawedzerwa kuHPMC, HPMC ichapararira nekukurumidza mumvura isina kugadzira zvinhu zvisinganyungudike. Izvi zvinonyanya kukonzerwa nekuti periodic acid ine dihydroxyl groups iri panzvimbo ye ortho pa glycogen yakapararira.
