HPMC (HYDROXYPROPYL MetHylcellose) is is is is-ionic cellylose inoshandiswa zvakanyanya sediki, stabilizer, emulsifier akasiyana-siyana ekushandisa maindasitiri. Mumakore achangopfuura, HPMC yave inowedzera kuwedzera mukugadzirwa kweuchi kweuchi kwechiyero nekuda kwezvivakwa zvaro zvakasarudzika uye hunhu.
HoneyCombb ceramics ndiyo yakakosha mhando yeCeramic inoratidzwa nehuchi-senge sizi yemuchina kana nzira yekumhanya kuburikidza navo. Iyi nzira inowanzo zadzwa nemhepo kana mamwe magasi, ichipa huchi ceramic yakanaka kwazvo manhamba, inopisa uye yemakemikari zvivakwa. HoneyCombi dzinowanzo shandiswa muindasitiri maindasitiri senge contaltic vashanduri, vanodziya mafirita uye vanodziya venhema nekuda kwenzvimbo yavo yakakwirira pamusoro pekodhi, kudzvinyirira kuderera uye kudzvinyirira kwakanakisa.
Kuti ubudise honeycb ceramics, slurry ye ceramic poda uye binder yakadururwa mune imwe mold ine huchi core. Mushure mekupfidza slurry Nekudaro, imwe yematambudziko makuru mukugadzira ceramic honeycombs kusimba kweiyo slurry. Iyo slurry inoda kuve yakagadzikana zvakakwana kuti izadze huchi uye kudzivirira chero kukanganisa, kupwanya kana kuremara mu chigadzirwa chekupedzisira.
Apa ndipo panowanikwa HPMC mukutamba. HPMC ine yakanakisa mvura yekuchengetwa kwemvura, viscosity uye kuomesa zvivakwa, izvo zvinoita kuti ive yakanaka yakanakisa uye stabilizer yeuchi ceramics. Nekuwedzera HPMC to ceramic slurry, iyo visikopo yeiyo slurry inowedzera, iyo inobatsira mukuchengetedza chimiro chayo uye kudzivisa kuraswa kana kugadzirisa nguva yekukanda. Mukuwedzera, HPMC inobatsira kuvandudza iyo yekushambadzira pakati peCeramic zvikamu, nekudaro ichisimbisa simba rekuita uye kugadzikana kweuchi kwehuchi ceramic chimiro.
Pamusoro pekukakavara uye kusimbisa zvivakwa, HPMC inopa zvimwe zvinokonzerwa nemamwe cellular ceramics. Semuenzaniso, HPMC inogona kuita seyava yaimboita, ichibatsira kugadzira yunifomu uye yakadzora mapores mune ceramic zvivakwa. Uyezve, izvi zvinogona kuwedzera nzvimbo yemusoro uye hupfumi hweuchi hweuchi, nekudaro uchisimbisa mashandiro azvo secakitori kana yefaira. Mukuwedzera, HPMC inoenderana nemhando dzakasiyana siyana dzeCeramic Pounds, ichiita kuti iite yakakodzera kune huwandu hwakawanda hwehuchi hweuchi hwekushandisa.
Nekudaro, pane mamwe matambudziko anoenderana nekushandisa HPMC seanotenderedza uye stabilizer yeuchi ceramics. Chimwe chezvinetso chikuru ndechekukudzwa kweHPMC yekuvhara uye viscosity. Yakawandisa HPMC inogona kukonzera yakawandisa viscosity, iyo inogona kukanganisa kuyerera kweiyo slurry uye kutungamira kuremara muchero yekupedzisira. Kune rimwe divi, idiki hpmc inogona kunge isingagone kugadzikana kwakaringana uye kushushikana, izvo zvinogona kukonzera huchi ceramic chimiro chekupaza kana deform. Naizvozvo, zvakakosha kuwana chiyero chakakodzera cheHPMC yekuvhara uye viscosity zvichibva pane chaiyo application zvinodiwa.
Rimwe dambudziko mukushandisa HPMC ndiko kugadzikana kwayo. Huchi cereracs dzinowanzo kudzingwa pakudziya kwakanyanya, izvo zvinogona kukonzera hpmc kusvibisa kana kuora. Izvi zvinoenderana zvinogona kukanganisa mechancal uye makemikari zvivakwa zveuchi cheuchi ceramic chimiro. Naizvozvo, zvakakosha kwazvo kusarudza giredhi rakakodzera reHPMC nekugadzikana kwakaringana uye kuwirirana neCeramic Pound.
HPMC ndeye multifauntional advertitive iyo ine zvakawanda zvakanakira sedhickener uye stabilizer yeuchi ceramics. Zvivakwa zvaro zvakasarudzika uye zvivakwa zvinoita kuti zvive zvakanaka pakuvandudza kugadzikana, kushamwaridzana uye nemakaniki simba reuchi kweuchi cramic zvivakwa. Nekudaro, matambudziko anoenderana nekushandiswa kwaro, akadai sekubhadhara kwekusangana, zvokuona, uye kugadzikana kwekunyora, kunoda kunyatsotarisirwa kuve nechokwadi chekuita zvakanaka uye kuita kwechigadzirwa chekupedzisira.
