1. Chii chinangwa chikuru chehydroxypropyl methyl cellulose (HPMC)?
HPMC inoshandiswa zvakanyanya mukuvaka, machira, ekugadzira resin, ceramics, mushonga, chikafu, machira, kurima, zvizorwa, fodya uye mamwe maindasitiri.
HPMC inogona kukamurwa kuita giredhi rekuvaka, chikafu giredhi uye yekurapa giredhi zvinoenderana nechinangwa chayo.
Parizvino, zvigadzirwa zvemumba zvakawanda ndezve giredhi rekuvaka. Mugiredhi rekuvaka, putty poda inoshandiswa muhombe, inenge 90% inoshandiswa kune putty poda, uye imwe yasara inoshandiswa simende dhaka uye glue.
2. Kune marudzi akawanda ehydroxypropyl methyl cellulose (HPMC). Ndeupi musiyano pakati pekushandiswa kwavo?
HPMC inogona kukamurwa kuva pakarepo mhando uye inopisa nyunguduka mhando.
Chigadzirwa chacho chinopararira nokukurumidza mumvura inotonhora uye chinopera mumvura. Panguva ino, mvura haina viscosity, nokuti HPMC inongopararira mumvura uye haina kunyatsopera. Anenge maminetsi maviri, viscosity yemvura yakawedzera zvishoma nezvishoma, ichigadzira sparent viscous colloid.
Instant type, yakafararira maapplications, inogona kushandiswa mune putty poda uye dhaka, pamwe chete mune yemvura glue uye pendi.
Iyo inopisa-yakanyunguduka chigadzirwa, kana ikasangana nemvura inotonhora, inogona kupararira nekukurumidza mumvura inopisa uye inonyangarika mumvura inopisa. Kana tembiricha yadonha kusvika kune imwe tembiricha, viscosity inooneka zvishoma nezvishoma kusvika yakajeka viscous colloid yaumbwa.
Kupisa kunyungudika mhando inogona chete kushandiswa muputty poda uye dhaka.
3. Ndedzipi nzira dzekuparara kwehydroxypropyl methyl cellulose (HPMC)?
Mvura inopisa yekumisa nzira: Sezvo HPMC isinganyungudika mumvura inopisa, HPMC inogona kuparadzirwa zvakafanana mumvura inopisa padanho rekutanga, uye yobva yanyungudika nekukurumidza kana yatonhodzwa. Nzira mbiri dzakajairika dzinotsanangurwa sezvizvi:
(1) Isa huwandu hunodiwa hwemvura inopisa mumudziyo uye kupisa kusvika ku70°C. Zvishoma nezvishoma wedzera hydroxypropyl methylcellulose nekukasira kunonoka, tanga HPMC ichiyangarara pamusoro pemvura, uye ipapo zvishoma nezvishoma gadzira slurry, uye kutonhorera slurry nekukurudzira.
(2). Isa 1/3 kana 2/3 yehuwandu hunodiwa hwemvura mumudziyo wopisa kusvika 70°C. Maererano pamusoro nzira, kuparadzira HPMC kugadzirira inopisa mvura slurry; wobva wawedzera huwandu hwakasara hwemvura inotonhorera kune inopisa mvura slurry. Mune slurry, tonhorera musanganiswa mushure mekusimudzira.
Powder kusanganisa nzira: Sanganisa HPMC hupfu nehuwandu hukuru hwezvimwe zviyo zvehupfu nemusanganisi, wobva wawedzera mvura kuti inyunguduke, ipapo HPMC inogona kunyungudutswa panguva ino pasina kudhumhana, nekuti kona yega yega diki, pane zvishoma zvishoma zveHPMC. Hupfu huchanyungudika pakarepo kana hwasangana nemvura.
4. Nzira yekutonga sei kunaka kwehydroxypropyl methylcellulose (HPMC) nyore uye intuitively?
(1) Kuchena: Kunyangwe kuchena kusingakwanise kuona kana HPMC iri nyore kushandisa, uye kana inopenya yakawedzerwa mukuita kwekugadzira, ichakanganisa kunaka kwayo. Zvisinei, zvizhinji zvezvigadzirwa zvakanaka zvine kuchena kwakanaka.
(2) Fineness: Kunaka kweHPMC kunowanzo 80 mesh uye 100 mesh, 120 mesh ishoma, iyo yakatsetseka kunaka, kazhinji zviri nani.
(3) Transmittance: Mushure mekuisa HPMC mumvura kuti iite yakajeka colloid, tarisa kutapurirana kwayo. Iyo yakakura iyo transmittance, zviri nani, zvichiratidza kuti kune mashoma insolubles mukati.
(4) Chiyero: chikuru chikamu, chinorema ndicho chiri nani. Iyo yakanyanya kujeka inowanzoitika nekuda kweiyo yakakwira hydroxypropyl zvirimo, uye iyo yakakwirira iyo hydroxypropyl yemukati, zviri nani kuchengetedza mvura.
5. Ndeapi makuru ehunyanzvi zviratidzo zvehydroxypropyl methyl cellulose (HPMC)?
Hydroxypropyl yemukati uye viscosity, mazhinji ayo ane hanya nezve izvi zviviri zviratidzo. Kuchengetwa kwemvura kunowanzo kuve nani kune avo vane yakakwira hydroxypropyl zvemukati. High viscosity, kuchengetedza mvura, hama (pane mhedziso) zviri nani, uye high viscosity, zviri nani kushandiswa mumatope esimende.
6. Ndezvipi zvinhu zvakakosha zvehydroxypropyl methyl cellulose (HPMC)?
Iyo huru yezvigadzirwa zveHPMC: yakanatswa donje, methyl chloride, propylene oxide, nezvimwe.
7. Ndeipi basa guru rekushandiswa kwehydroxypropyl methyl cellulose (HPMC) mu putty powder? Pane chemical reaction here?
Mune putty poda, HPMC inoita mabasa matatu ekukora, kuchengetedza mvura uye kuvaka.
Kukora: Cellulose inogona kukobvu kumisa uye kuchengeta mhinduro yunifomu uye kumusoro uye pasi, uye anti-sagging.
Kuchengeta mvura: ita kuti putty poda iome zvishoma nezvishoma, uye batsira grey calcium kuita pasi pekuita kwemvura.
Kuvaka: Cellulose ine lubricating effect, iyo inogona kuita kuti putty powder ive nekushanda kwakanaka.
HPMC haitore chikamu mune chero chemakemikari reaction, inongoita basa rekutsigira.
8. Chii chinonzi kunhuwa kwehydroxypropyl methyl cellulose (HPMC)?
Iyo HPMC inogadzirwa nenzira yekunyungudutsa inoshandisa toluene uye isopropanol sechinhu chinonyungudutsa. Kana isina kugezwa zvakanaka, inenge iine kunhuhwirira kwasara.
9. Nzira yekusarudza yakakodzera hydroxypropyl methylcellulose (HPMC) nekuda kwezvinangwa zvakasiyana?
Kushandiswa kweputty powder: zvinodiwa zvakaderera, viscosity ndeye 100,000, zvakakwana, chinhu chinokosha ndechokuchengeta mvura iri nani.
Kushandiswa kwedhaka: zvinodiwa zvakanyanya, high viscosity, 150,000 iri nani.
Glue application: zvigadzirwa zvekukurumidza zvinodiwa, zvine viscosity yakakwirira.
10. Kushandiswa kwehydroxypropyl methyl cellulose (HPMC) mu putty powder, chii chinokonzera kuti putty powder ibudise mabhubhu?
