Mukutonga kwekugadzira putty poda yakaoma dhiri, kusarudzwa kwekusarudza kwehydroxpropropyl methylcellose (HPMC) yakakosha pakuita kwechigadzirwa. HPMC ndeye yakakosha cellulose ether, inoshandiswa zvakanyanya muzvivakwa zvekuvaka, kunyanya muPutty hupfu uye yakaoma motokari, ichiridza dzakasiyana-siyana mabasa akakura, kuchengetwa kwemvura, uye kugadzirisa maitiro ekuvaka.
Mabasa uye mhedzisiro yeHPMC
MuPutty Poda Dry Darar, HPMC inonyanya kutamba mabasa anotevera:
Kudzokorora kwemvura: HPMC inogona kutora uye kuchengetedza mvura, kuderedza kurasikirwa kwemvura panguva yekushandisa, nekudaro nekutsvaga nguva yekudyara yezvinyorwa uye ichine hunhu hwekuvaka.
Kukakavara: HPMC inopa yakakodzera viscosity uye kuwirirana, saka iyo denty poda kana kuti yakaoma dhiraivha inopararira panguva yekusanganisa, kuwedzera kushushikana uye kusimba kwekuvaka.
Anti-slip: Iyo viscosity yakapihwa neHPMC inogona kunyatso kuderedza iyo yekutsvedza yezvinhu panguva yekuvaka, kunyanya panguva yekuvaka wall.
Kuvandudza Anti-Sagging: Wedzera kugadzikana kwezvinhu panguva yekuvira kwekuvira kuti udzivise kutsvedza.
Kusarudzwa kweHPMC viscosity
Iyo viscosity yeHPMC yakanangana nayo yekuita uye kushandiswa kwekushandisa kwePutty poda yakaoma, saka zvakakosha kwazvo kusarudza iyo yakakodzera viscosity. Heano mamwe mikana uye kufunga kwesarudzo yekusarudza viscosity:
1. Zvinodiwa zvekuvaka
Yakakwira viscosity HPMC (100,000CPS uye pamusoro):
Inokodzera kuvakwa neyakanyanya verticity zvinodiwa, senge poro poda pamadziro akakwirira.
Inogona kuvandudza zvivakwa-zvinotsvedza-kutsvedza uye kuderedza kuyerera kwezvinhu pane zvimedu zvemukati.
Wedzera kuchengetwa kwemvura, yakakodzera kupisa kwakanyanya kana kuoma mamiriro emamiriro ekunze kudzivirira kurasikirwa kwakanyanya kwemvura.
Ipa simba rakasimba rakasimba, iyo inokodzera pakuvakwa kwemakonzo akaumbwa.
Pakati peva viscosity HPMC (20,000cps kusvika 100,000CPS):
Inokodzera kujairika kwekuvaka kuvaka uye pasi kuwanda.
Inorarukira nguva yekuvhiya uye yekuvakira fluity, yakakodzera mamiriro akasiyana emamiriro ekunze.
Inokodzera zvikumbiro izvo zvinoda zvakanaka anti-sagging asi haadi yakanyanya kukwirira viscosity.
Yakadzika viscosity HPMC (10,000CPS uye pazasi):
Inoshandiswa kune prody poda inoda yakakwira fluidity, yakadai seyakaonda marara.
Inobatsira kuvandudza kuwanda uye kushoma kwezvinyorwa uye zvakakodzera kuti ubatwe zvakanaka.
Yakakodzera nzvimbo nenzvimbo dzakanyorova dzekuvaka.
2. Kuumbwa kwezvinhu uye chiyero
FomuUlas ine yakakwira filer yezvinyorwa kazhinji inoda yakakwira viscosity Hpmc kuti ipe kukwana kwakakwanira simba uye kuve nechokwadi chekugadzikana kwechinyorwa.
Mafomula ane allalas ane aggregates kana achida kuseka zvakanyanya anogona kushandisa yakaderera viscosity HPMC kuti ive nechokwadi chehunhu hwakanaka uye kubhururuka kwechinyorwa panguva yekuvaka.
FomuUlas nePolymers Polymers inogona kuda pakati kana yakaderera viscosity HPMC kuti udzivise zvakanyanya kukanganisa kuita kuita kwekuvaka.
3. Mamiriro ekunze
Kupisa tembiricha uye kuoma mamiriro ekunze: Sarudza Yakakwira viscosity HPMC kuti uwedzere nguva yakavhurika yezvinhu uye kuderedza matambudziko ekuvaka anokonzerwa kubuda kwemvura.
Tembiricha yakaderera uye yakanunurwa nzvimbo: Sarudza yakaderera kana yepakati viscosity HPMC kuti udzivise kabhuku kana kuwandisa zvevatarisiti zvezvinyorwa zviri munzvimbo yakanyorova.
4. Maitiro ekuvaka
Spaning Spray inowanzoda fluidity yakanaka yezvinyorwa, saka yakaderera viscosity HPMC inosarudzwa.
Zvekunyorera zvinyorwa, pakati peVicesity HPMC inogona kusarudzwa kuve nechokwadi chekuvaka kugona kwekuvaka.
Kuedza uye Kudzora kweHPMC viscosity
Paunenge uchisarudza HPMC, kuwedzera kune iyo viscosity kukosha, yayo solubility, mhinduro transpency, kudzokorora kwemvura, nezvimwe zvinofanirwa zvakare kufungwa nezvazvo. A rotcational parcometer inowanzo shandiswa kuyera iyo yeHPMC solution pakasiyana tembiricha uye Shear tate kuti ive nechokwadi chekuita nezvayo mukushandisa chaiko mukushandisa chaiko.
Laboratori Kuongororwa
Iyo viscosity uye kuita kweHPMC inogona kuedzwa mumarabhoritari nematanho anotevera:
Kugadziriswa kwekunyangarirwa: Dissolve HPMC pamhepo tembiricha uye simbisa kupaza kwakakwana uye hapana zvimedu.
Viscossity Kuyerwa: Shandisa iyo yekutenderera yekutenderera kuyera iyo viscosity pane dzakasiyana shear mitengo.
Kuchengeta mvura Kuongorora
Chikumbiro Chekushandisa: sungidzira mamiriro chaiwo ekuvaka kuti uone mhedzisiro yeHPMC pane yekuvaka kuita kwePutty poda yakaoma yakaoma.
Mhando yekudzora
Munguva yekugadzira, imwe neimwe batch yeHPMC inoda kudzorwa nemhando, kusanganisira yekuyedza yekuyedza, kuongororwa kwekuedza, nezvimwe, kuti uve nechokwadi chekuenderana uye kuita kwakagadzikana.
Kusarudza HPMC ine yakakodzera viscosity inokosha yekugadzirwa kweiyo putty poda yakaoma yakaoma. Yakakwira viscosity HPMC yakakodzera nzvimbo dzekuvaka dzinoda kukwikwidza kwakakwirira-sAG Vagadziri vanofanirwa kurudzira viscosity yeHPMC zvichibva pane chaiyo yekushandisa zviitiko, mamiriro ekunze, uye zvinodikanwa zvekuvaka, zvakasanganiswa nemabhiramu emhedzisiro, kugadzirisa zvigadzirwa zvemhando yepamusoro uye zvinokuvadza.
