Hydroxyprishpropyl methyl cellelose hpmc matambudziko

1. Ndeipi iyo huru kushandiswa kwehydroxypropyl methyl cellulose?

HPMC inoshandiswa zvakanyanya mukuvakwa, marara, majasi, ceramics, mushonga, chikafu, zvinyorwa, zvekurima, zvidhori, zvidhori uye mamwe maindasitiri. HPMC inogona kukamurwa kuita giredhi reindasitiri, giredhi rekudya uye giredhi rekurapa zvinoenderana nekushandiswa.

2..

HPMC inogona kukamurwa kupinda Anenge maminetsi maviri, iyo viscosity yemvura inowedzera zvishoma, kugadzira yakajeka uye inonamira gel. Zvipfuyo zvezvipfuyo zvinonyungudika, zvinokatyamadzwa mumvura inotonhora, chinogona kukurumidza kupararira mumvura inopisa, sekupisa kwemvura inopisa, sekudziya kwemvura inodonha

1) Whiteness, kunyangwe hazvo whiteness haikwanisi kusarudza kuti HPMC yakanaka, uye kana ichiwedzerwa mukugadzirwa kwechinguvana, uye, zvigadzirwa zvakanaka zvakanyanya kuchena kwakanaka.
2) chidimbu: HPMC chidiki chinowanzoita makumi masere nemakumi mairi mesh uye zana nemakumi mashanu emakumi maviri, ane madiki mashoma, iye akanaka kwazvo.
3) Kupfuurirazve: HPMC mumvura, kuwongorora chidimbu chechiedza chevakanaka, chingotumira kugadzirwa kwechiitiko.
4) proportion: the larger the proportion, the heavier the better, than the major, generally because of the high content of hydroxypropyl inside, hydroxypropyl content is high, the water retention is better.

4. Ndedzipi nzira dzekupaza dze hydroxyprupyl methyl cellulose?
1) Mhando dzese dzinogona kuwedzerwa mune izvo zvinyorwa nenzira yakaoma yekusanganisa;
2) Unoda kuwedzerwa zvakananga kune yakajairika yekupisa kwemvura mhinduro, zviri nani kushandisa inotonhora mvura kupararira, mushure mekuwedzera kazhinji mumaminitsi gumi-90 kusvika kumhepo (stir stir stir)
3) Mhando dzakajairika dzinogona kunyungudutswa mushure mekusanganisa uye kupararira nemvura inopisa uye kuwedzera mvura inotonhora mushure mekunudza uye kutonhora;
4) Kana ichinyungudika, kana chiitiko cheAgglomerating zvikaitika, imhaka yekuti kusimudzira hakuna kukwana kana iyo yakajairika muenzaniso inowedzerwa mumvura inotonhora. Panguva ino, inofanira kukurudzirwa nekukurumidza.
5) Kana mabhuru anoitika panguva yekupararira, ivo vanogona kubviswa nekumira kwemaawa 2-12 (nguva chaiyo zvinoenderana nekuenderana kwemhinduro) kana nekumanikidza, kana nekuwedzera huwandu hwakakodzera hwekuita mumiririri.

5 hydroxypruppropyl methyl cellelose mune vhoriyamu yePutty poda?
HPMC mukushandisa chaiko kwehuwandu, nenzvimbo yemamiriro ekunze, tembiricha yemhando yemhando, putty poda formula yemhando dzakasiyana, uye pane misiyano yakatenderedza, kazhinji pakati pe4-5 makiromita.

6. Ndeipi iyo yakakodzera viscosity ye hydroxyprusyl methyl cellulose?
Putty poda kazhinji 100000 inogona, maumbwe anokwanisa kukwirira, kusvika 150000 zvakanaka chete, uye Hpmc inonyanya kukosha basa kuchengetwa kwemvura, kuteverwa nekukora. MuPutty poda, chero bedzi kuchengetwa kwemvura kwakanaka, iyo visikoka yakaderera (7-8), zvinoita kuti vanhu vazhinji vanopfuura zviuru zana, iyo visikoka yekuchengetwa kwemvura haina zvakawanda.

7. Ndezvipi zvinhu zvikuru zvekushandisa zvehydroxyprupyl methyl cellulose?
HPMC mainini main zvinhu zvinhu: Yakanatswa Cotton, chlomethane, propylene oxide, zvimwe zvigadzirwa, piritsi alkali, acid tluene.

MuPutty poda, kuremerwa, kudzokorora kwemvura uye kuvakwa kwemabasa matatu. Kukora, cellulose kunogona kuitwa kumiswa, kuti mhinduro yacho ichiramba yanyatsojeka uye pasi basa reAnti-kuyerera kurembera. Kuchengeta kwemvura: Gadzira putty poda yakaoma zvishoma, auxileary grey calcium mukuita kwemvura. Kuvaka: Cellulose Lubrication, kunogona kuita kuti purode itty ine kunaka kuvaka. HPMC haibatanidzi mune chero mhedzisiro yemakemikari, asi inopa basa rinotsigira.

9 .hydroxyprondryl methyl cellelose haisi-ionic cellulose eter, saka chii chisiri chisiri-ionic?
MuMitemo yaLayman, inert zvinhu hazvipindirani mumakemikari maitiro.
CMC (CarboxyMethyl Cellelose) ndeye cationic cellulose, saka kusangana nekoge calcium ichava bhinzi curd.

. Kana tembiricha yedofu inodarika 40 degrees, kuchengetwa kwemvura methyl cellelose kuchave kwakaipisisa, uko kunokanganisa zvakanyanya kuvakwa kwemotokari.
. Kudonhedza pano kunoreva kune chinonamatira simba kwakanzwa pakati pechishandiso uye madziro substrate nemushandi, ndiko kuti, iyo Shear Ristance yerudzi. Kududzira kwakakura, shear kurwisa mongwe yakakura, iyo simba rinodiwa nevashandi vari mumamiriro ekushandisa zvakare rakakura, uye kuvakwa kwemutyairi murombo.
