Nhanganyaya kuIndustrial Grade HPMC

1. Chii chinonzi Industrial Grade HPMC

Giredhi reMaindasitiriHPMC (Hydroxypropyl Methylcellulose)imhando ye ether inogadzirwa ne cellulose isina ionic, inowanzova upfu huchena kana kuti hwero zvishoma. Inogadzirwa kubva kumafiber edonje echisikigo kuburikidza nekurapa kwealkali uye maitiro akasiyana-siyana emakemikari (akadai se etherification), uye ine biocompatibility yakanaka uye kugadzikana kwemakemikari. Nekuda kwehunhu hwayo hwakasiyana hwepanyama nemakemikari, HPMC inoshandiswa zvakanyanya muminda yakawanda yemaindasitiri senge kuvaka, kuputira, ceramics, uye makemikari ekurima.

2. Kushanda Kukuru kweGiredhi reIndasitiri HPMC

Kukora

HPMC ine kugona kukuru kwekukora uye inogona kuwedzera kunaka kwemvura inoyerera, nokudaro ichivandudza magadzirirwo, slurry uye hunhu hwekukwesha kwechigadzirwa.

Kuchengetwa kweMvura

Mukushandiswa kwakadai semortar neputty, HPMC inogona kuvandudza zvakanyanya kuchengetwa kwemvura kwechinhu chacho, kudzivirira kurasikirwa nemvura nekukurumidza, kuwedzera nguva yekushanda, uye kuvandudza huwandu uye kunamira kwechigadzirwa chapera.

Kugadzira Mafirimu

HPMC inogona kugadzira firimu rakasimba uye rinoonekera pamusoro, zvichiita kuti chigadzirwa chive nechimiro chakanaka chekudzivirira uye chinopenya.

Kupararira uye emulsification

HPMC inogona kupararira mumvura zvakanaka uye inogona kushandiswa semushonga wekusimbisa muviri uye kugadzirisa kugadzikana uye kugadzikana kwemushonga.

Kupisa kwemafuta

Mvura inobuda muHPMC inozogadzira gel kana yapiswa kusvika patembiricha yakati. Iyi gel inodzoreka inobatsira zvikuru mune mamwe mashandisirwo akakosha.

3. Nzvimbo huru dzekushandisa dzeHPMC dzemhando yepamusoro

Indasitiri yekuvaka

Dhaka rakasanganiswa nemvura (rakaita sedhaimani remataira, dhaka replaster, dhaka rinozvienzanisa): HPMC inogona kuvandudza kuchengetedza mvura, kunamira uye mashandiro ekuvaka kwedhaka.

Upfu hweputty: Hunovandudza kutaridzika kwechivakwa, kudzivirira kutsemuka nekubuda kwemvura, uye kunatsiridza kunaka kwechigadzirwa chapera.

Sisitimu yekudzivirira kunze (EIFS): Inosimudzira kunamira uye kuchinjika kwedhaka uye inowedzera kugara kwenguva refu.

Indasitiri yekupenda

HPMC inoshandiswa semushonga wekusimbisa muviri, mutsigiri uye mugadziri wefirimu kuti ivandudze mashandiro ekudzivirira kusadzikama, kugadzikana uye kufanana kwepafirimu.

Indasitiri yeCeramic

Mukugadzirwa kwemazai eceramic, HPMC inoita basa rekuchengetedza mvura, kukwiza mafuta, kuumba, nezvimwewo, zvichibatsira kuvandudza huwandu hwechigadzirwa uye kuramba kutsemuka.

Zvigadzirwa zvemakemikari zvezuva nezuva

Kuwedzera HPMC muzvishandiso zvekuchenesa nedhishi rekuchenesa kunogona kuwedzera kuenderana kwechigadzirwa, kuita kuti furo rive rakapfava uye rigare kwenguva refu, uye kuvandudza kugadzikana kwefomula.

Kuchera mafuta

Sechinowedzerwa pakushandisa mvura yekuboora, HPMC inogona kugadzirisa rheology yemvura yekuboora, kudzivirira kuputsika kwemadziro etsime, uye kuvandudza kushanda zvakanaka kwekuchera.

4. Mashandisirwo eHPMC yemhando yepamusoro yeindasitiri

Kazhinji, HPMC inofanira kudirwa mumvura inotonhora kuti igadzire mhinduro yakafanana kuti ishande zvizere. Matanho akajairika ekushandisa ndeaya anotevera:

Dururirai HPMC zvishoma nezvishoma uye zvakaenzana mumvura inotonhora yakasanganiswa kuti musaungane.

Ramba uchikurunga kusvika zvatanga kupararira.

Mira kwenguva yakati (kazhinji maawa anopfuura maviri) kuti unyorovese uye unyungudise cellulose zvizere.

Kana zvichidikanwa, kurungai nokungwarira kusvika mvura yanyatsojeka kana kuti yanyatsojeka yagadzirwa.

Mukushandiswa chaiko kwemaindasitiri, huwandu hweHPMC hunowedzerwa dzimwe nguva hunogadziriswa sezvinodiwa, hunowanzo dzorwa pakati pe0.1% ne2.0%, uye chiyero chaicho chinoenderana nesystem yefomula uye mhedzisiro inodiwa.

5. Kudzora mhando uye kusarudzwa kwesarudzo

HPMC yemhando yeindasitiri ine magadzirirwo akasiyana e viscosity (akadai se400 mPa.s, 15000 mPa.s, nezvimwewo) uye dhigirii rekutsiva (kureva dhigirii rekutsiva hydroxypropyl nemethyl) zvichienderana nezvinodiwa zvakasiyana zvekushandisa. Kusarudza modhi yakakodzera kune simba guru pakushanda kwechigadzirwa. Zvinhu zvekuedza zvemazuva ese zvinosanganisira:

Viscosity (2% mhinduro patembiricha yemumba)

Hunyoro

Zviri mukati medota

Zviri mukati meMethoxy nehydroxypropyl

pH kukosha (1% mhinduro yemvura)

HPMC yemhando yepamusoro yeindasitiri inofanira kunge iine hunhu hwemadota mashoma, kupararira kwakanaka, kusimba kwakasimba, uye kukurumidza kunyungudika.

6. Kuchengeta nekurongedza

HPMC inofanira kuchengetwa munzvimbo inotonhorera, yakaoma, ine mhepo inofefetera zvakanaka, ichidzivirira kupisa kwakanyanya, hunyoro uye chiedza chezuva kudzivirira kunyungudika kwehunyoro, kubatanidzwa kana kushanduka kwekushanda. Inowanzo kuputirwa mumabhegi epepa ane layer yakawanda akafukidzwa nemabhegi epurasitiki. Chimiro chepurasitiki chakajairika i25 kg/bhegi, chinogonawo kugadziriswa zvichienderana nezvinodiwa nevatengi.

HPMC yemhando yeindasitiriine basa risingatsivike muminda yakawanda yemaindasitiri nekuda kwehunhu hwayo hwakanaka hwemuviri nemakemikari. Nekukwira kwezvinhu zvekuvaka zvakasvibirira, machira asingakuvadzi nharaunda uye zvinhu zvine musanganiswa wepamusoro, kudiwa kweHPMC yepamusoro kuri kukurawo. Mune ramangwana, nekugadziriswa kwemaitiro ekugadzira uye kuwedzera kweminda yekushandisa, HPMC yemhando yepamusoro icharatidza mukana wakakura wekuvandudza.
