Chii chinonzi hydroxypropyl methyl cellulose?

Hydroxypropyl methyl cellulose (HPMC), inozivikanwawo se hydroxypropyl methylcellulose, cellulose hydroxypropyl methyl ether, cellulose, 2-hydroxypropylmethyl ether, PROPYLENE GLYCOL ETHER OF METHYLCELLULOSE, CAS Nha. 9004-65-3, inogadzirwa kubva ku cellulose yakachena kwazvo ne etherification yakakosha pasi pemamiriro e alkaline. HPMC inogona kukamurwa kuita building grade, food grade uye pharmaceutical grade zvichienderana nekushandiswa kwayo. Inoshandiswa zvakanyanya mukuvaka, chikafu, mishonga nezvizoro, makemikari ezuva nezuva nemamwe maindasitiri.

Ndezvipi zvinoshandiswa neHPMC?

Indasitiri yekuvaka

1. Duri rekugadzira matombo
Kusimbisa kunamira pamusoro pematombo ekuvaka kunogona kuwedzera kuchengetwa kwemvura, nokudaro zvichivandudza kusimba kwedhaka, uye kuvandudza kunyorova uye purasitiki kuti zvibatsire kushanda zvakanaka kwekuvaka. Kuvaka kuri nyore kunochengetedza nguva uye kunovandudza kushanda zvakanaka kwemari.
2. Zvigadzirwa zveGypsum
Inogona kuwedzera nguva yekushanda kwedhaka uye kugadzira simba remuchina rakawanda panguva yekusimba. Kuputira kwepamusoro-soro kunoumbwa nekudzora kugadzikana kwedhaka.
3. Pendi inobviswa nemvura uye inobvisa pendi
Inogona kuwedzera nguva yekushanda kwayo nekudzivirira kunaya kwemvura, uye inoenderana zvakanaka uye ine kugadzikana kwakanyanya kwehupenyu. Kunyungudika kwayo kunokurumidza uye hakusi nyore kuungana, izvo zvinobatsira kurerutsa maitiro ekusanganisa. Inogadzira hunhu hwakanaka hwekuyerera, kusanganisira kudonha kwakaderera uye kuenzana kwakanaka, inoita kuti pamusoro payo pave nependi yakanaka, uye inodzivirira kudzika kwependi. Wedzera kusimba kwemuchina wekubvisa pendi wakagadzirwa nemvura uye muchina wekubvisa pendi weorganic solvent, kuitira kuti muchina wekubvisa pendi usabude kubva pamusoro pebasa.
4. Namatira yeceramic
Zvinhu zvinosanganiswa nemafuta akaoma zviri nyore kusanganisa uye hazviunganidzike, zvichichengetedza nguva yekushanda nekuti zvinoshandiswa nekukurumidza uye zvinobudirira, zvichivandudza kugona kugadzikiswa uye kuderedza mari. Wedzera kushanda zvakanaka kwekuisa mataira uye kupa kunamira kwakanaka nekuwedzera nguva yekutonhodza.
5. Zvinhu zvepasi zvinozvienzanisa
Inopa kusviba uye inogona kushandiswa sechinhu chinodzivirira kugadzika pasi kuti ibatsire kuvandudza kushanda zvakanaka kwepasi. Kudzora kuchengetwa kwemvura kunogona kuderedza zvikuru kutsemuka nekuoma.
6. Kugadzirwa kwematombo ekongiri akaumbwa
Inowedzera kugona kwekugadzirisa zvinhu zvakaburitswa, ine simba rekubatanidza uye mafuta akawanda, uye inovandudza kusimba kwemvura uye kunamira kwemachira akaburitswa.
7. Kuzadza plate joint
Hydroxypropyl methyl cellulose ine mvura inochengetedza zvakanaka, inogona kuwedzera nguva yekutonhodza, uye mafuta ayo akawanda anoita kuti kuiswa kwayo kuve kwakapfava. Inovandudza kunaka kwenzvimbo, inoita kuti ive yakapfava uye yakaenzana, uye inoita kuti nzvimbo yekubatanidza ive yakasimba.
8. Gypsum yakavakirwa pa simende
Inochengetedza mvura yakawanda, inowedzera nguva yekushanda kwedhaka, uye inogonawo kudzora kupinda kwemhepo, nokudaro ichibvisa zvidimbu zvidiki zvejira uye kugadzira nzvimbo yakatsetseka.

Indasitiri yezvekudya

1. Citrus yakakangwa: kudzivirira kuchena uye kuora nekuda kwekuora kwemichero yecitrus glycosides panguva yekuchengetwa, kuitira kuti irambe yakachena.
2. Zvigadzirwa zvemichero inotonhora: zvinowedzerwa mumuto wemichero nechando kuti kuravira kuve kuri nani.
3. Sosi: inoshandiswa semushonga wekusimbisa muviri kana kuti inosimbisa muto nedomasi.
4. Kuputira nekupukuta nemvura inotonhora: kunoshandiswa pakuchengetera hove dzakaomeswa nechando kudzivirira kusviba kweruvara uye kuora kwemhando. Mushure mekuputira nekupukuta nemethyl cellulose kana hydroxypropyl methyl cellulose aqueous solution, chando pachando.
5. Namatira yemapiritsi: Sechinamira chekuumba mapiritsi nemagranules, ine "kuputsika panguva imwe chete" kwakanaka (kuputsika nekukurumidza, kuputsika uye kupararira kana uchitora).

Indasitiri yemishonga

1. Kuvharira: Mushonga wekuvharira unogadzirwa kuita mushonga we organic solvent kana mushonga wemvura wekuisa mapiritsi, kunyanya wekuisa zvidimbu zvakagadzirwa mufiriji.
2. Mushonga unononoka: 2-3 magiramu pazuva, 1-2G panguva imwe chete, kwemazuva 4-5.
3. Mushonga wemaziso: Sezvo kumanikidzwa kwe osmotic kwe methyl cellulose aqueous solution kwakafanana nekwemisodzi, hainyanyi kutsamwisa maziso. Inowedzerwa mumushonga wemaziso semafuta ekubata ne lenzi yemaziso.
4. Jeli: Inoshandiswa sechinhu chepakutanga chejeli senge mushonga wekunze kana mafuta ekuzora.
5. Mushonga unoisa pamuviri: unoshandiswa semushonga unokodza uye unochengetedza mvura.

Indasitiri yezvizoro

1. Shampoo: Wedzera kusimba uye kugadzikana kwemabhurumu eshampoo, mushonga wekuwachisa uye sipo.
2. Mushonga wemazino: wedzera kuyerera kwemushonga wemazino.

Indasitiri yekubikira

1. Zvinhu zvemagetsi: sechinamira chinonamira che ceramic electric compactor ne ferrite bauxite magnet, chinogona kushandiswa pamwe chete ne 1.2-propanediol.
2. Mushonga weGlaze: unoshandiswa semushonga weglaze weceramics uye pamwe chete nependi ye enamel, izvo zvinogona kuvandudza kubatana uye kugona kushandiswa.
3. Dura rinonyungudutsa: Rinogona kuwedzerwa kudhaka rezvidhinha rinonyungudutsa kana zvinhu zvechitofu kuti riwedzere kuchena uye kuchengetedza mvura.

Mamwe maindasitiri

HPMC inoshandiswawo zvakanyanya mukugadzira resin yekugadzira, petrochemical, zvedongo, kugadzira mapepa, dehwe, inki yemvura, fodya nedzimwe nzvimbo. Inoshandiswa sechinosimbisa, chinonyungudutsa, chinosunga, chinosanganisa uye chinosimbisa muindasitiri yemachira.

Nzira yekuona sei kunaka kwehydroxypropyl methyl cellulose (HPMC) nemaziso?

1. Chromaticity: kunyangwe isingakwanise kuona zvakananga kana HPMC iri nyore kushandisa, uye kana chinhu chichena chikawedzerwa mukugadzirwa, hunhu hwayo huchakanganiswa. Zvisinei, zvigadzirwa zvemhando yepamusoro zvava kuda kutengwa.
2. Kupfava: HPMC ine ma meshes makumi masere uye ma meshes zana, uye ma meshes zana nemakumi maviri mashoma. Mazhinji ma HPMC ane ma meshes makumi masere. Kazhinji, kupfava kwe offside kuri nani.
3. Kutumira chiedza: isa hydroxypropyl methyl cellulose (HPMC) mumvura kuti igadzire colloid inoonekera, wobva waona kufambiswa kwayo kwechiedza. Kufambiswa kwechiedza kwakakura, zviri nani, zvichiratidza kuti hapana chinhu chisinganyunguduke mairi.
4. Simba remudenga rakasiyana: Simba remudenga rakasiyana rinorema, uye simba remudenga rakasiyana rinova nani. Chiyero chacho chakakosha, kazhinji nekuti huwandu hwehydroxypropyl hwakakwira. Kana huwandu hwehydroxypropyl hwakakwira, kuchengetedza mvura kunova nani.
Hydroxypropyl methyl cellulose inogara yakagadzikana kune acids uye mabhesi, uye mhinduro yayo yemvura inogara yakagadzikana zvikuru muhuwandu hwe pH = 2 ~ 12. Isu tiri vagadziri vane hunyanzvi. Kana uchida chigadzirwa ichi, unogona kutibata. Ndizvo zvese zvekugovana HPMC muchinyorwa chino. Ndinovimba zvinogona kukubatsira kunzwisisa HPMC.
