1. Kune marudzi akati wandei ehydroxypropyl methylcellulose HPMC, uye ndeupi musiyano uripo pakati pemashandisiro ayo?
Mhinduro: Hydroxypropyl methylcellulose HPMC inogona kukamurwa kuva pakarepo mhando uye inopisa-kunyunguduka mhando.Instant-type products zvinopararira nokukurumidza mumvura inotonhora uye inonyangarika mumvura.Panguva ino, mvura haina viscosity, nokuti HPMC inongopararira mumvura, hapana kunyungudika kwechokwadi.Mushure memaminitsi maviri, viscosity yemvura yakawedzera zvishoma nezvishoma, ichigadzira yakajeka viscous colloid.Zvigadzirwa zvinopisa-zvinopisa, paunosangana nemvura inotonhora, zvinogona kukurumidza kupararira mumvura inopisa uye kupera mumvura inopisa.Kana tembiricha yadzikira kune imwe tembiricha, viscosity inooneka zvishoma nezvishoma kusvika yakajeka viscous colloid yaumbwa.Iyo inopisa-yakanyunguduka mhando inogona kungoshandiswa muputty poda uye dhaka.Mumvura glue uye pendi, clumping phenomenon ichaitika uye haigone kushandiswa.Rudzi rwepakarepo rune huwandu hwakakura hwemaapplication.Inogona kushandiswa mu putty poda uye dhaka, pamwe chete mumvura glue uye pendi, pasina contraindications.
2. Chii chinangwa chikuru chehydroxypropyl methylcellulose (HPMC)?
A: HPMC inoshandiswa zvakanyanya mukuvaka, machira, ekugadzira resin, ceramics, mushonga, chikafu, machira, kurima, zvizorwa, fodya uye mamwe maindasitiri.HPMC inogona kukamurwa kuita: giredhi rekuvaka, giredhi rekudya uye giredhi remishonga zvinoenderana nechinangwa.Parizvino, zvizhinji zvezvigadzirwa zvepamba ndezvekuvaka giredhi.Mugiredhi rekuvaka, huwandu hweputty hupfu hwakakura kwazvo, inenge 90% inoshandiswa kune putty powder, uye imwe yakasara inoshandiswa kune simende dhaka uye glue.
3. Ndedzipi nzira dzekunyungudutsa dzehydroxypropyl methylcellulose HPMC?
Mhinduro: Kupisa mvura inopisa nzira: Sezvo HPMC isina kunyungudika mumvura inopisa, HPMC inogona kuparadzirwa zvakafanana mumvura inopisa padanho rekutanga, uye yobva yanyungudika nekukurumidza kana yatonhodzwa.Nzira mbiri dzakajairika dzinotsanangurwa sezvizvi:
1), wedzera 1/3 kana 2/3 yehuwandu hunodiwa hwemvura mumudziyo, uye kupisa kusvika 70 ° C, maererano nenzira ye1), paradzira HPMC, gadzirira slurry yemvura inopisa;wobva wawedzera huwandu hwakasara hwemvura inotonhora kumvura inopisa Mu slurry, musanganiswa wacho wakanyoroveswa mushure mekukurudzira.
Powder kusanganisa nzira: Sanganisa HPMC poda nehuwandu hukuru hwezvimwe zvinhu zvehupfu, nyatso sanganisa nemuvhenganisi, wobva wawedzera mvura kuti inyunguduke, ipapo HPMC inogona kunyungudutswa panguva ino pasina kuungana, nekuti pane chete HPMC diki mune yega yega. kakona kadiki.Upfu huchanyungudika pakarepo mukusangana nemvura.——Iyi nzira inoshandiswa nevanogadzira putty poda nedhaka.[Hydroxypropyl methylcellulose (HPMC) inoshandiswa seyakakora uye inochengetedza mvura mu putty powder mortar.
2), isa huwandu hunodiwa hwemvura inopisa mumudziyo, uye kupisa kusvika ku70 ℃.Iyo hydroxypropyl methylcellulose yakawedzerwa zvishoma nezvishoma nekukurudzira kunonoka, pakutanga HPMC yakayangarara pamusoro pemvura, uye zvishoma nezvishoma yakagadzira slurry, iyo yakanyoroveswa nekukurudzira.
4. Nzira yekutonga sei kunaka kwehydroxypropyl methylcellulose (HPMC) nyore uye intuitively?
Mhinduro: (1) Chaiyo giravhiti: iyo yakakura iyo chaiyo giravhiti, iyo inorema zvakanyanya nani.hombe, kazhinji nekuti
(2) Kuchena: Kunyangwe kuchena kusingataridzi kana HPMC iri nyore kushandisa, uye kana mumiriri wekuchena akawedzerwa mukugadzira, zvinokanganisa kunaka kwayo.Zvisinei, zvizhinji zvezvigadzirwa zvakanaka zvine kuchena kwakanaka.
(3) Fineness: Kunaka kweHPMC kunowanzo 80 mesh uye 100 mesh, uye 120 mesh ishoma.Yakawanda yeHPMC inogadzirwa muHebei ndeye 80 mesh.Kunyanya kunaka, zviri nani pane zvese.
(4) Transmittance: Isa hydroxypropyl methylcellulose (HPMC) mumvura kuti iite yakajeka colloid, uye tarisa iyo transmittance.Iyo yakakwirira iyo transmittance, zviri nani, zvichiratidza kuti kune zvishoma zvisinganyunguriki mu.Kupinda kwemaactors akatwasuka kazhinji kwakanaka, uye kuya kwemareactors akachinjika kwakaipisisa, asi hazvigone kutaurwa kuti kunaka kwemaactors ari nani pane emareactor akachinjika, uye pane zvakawanda zvinotaridza kunaka kwezvigadzirwa.Iyo hydroxypropyl yemukati mayo yakakwirira, uye iyo hydroxypropyl yemukati yakakwira, kuchengetwa kwemvura kuri nani.
5. Ndeapi makuru ehunyanzvi zviratidzo zvehydroxypropyl methylcellulose (HPMC)?
Mhinduro: Hydroxypropyl content uye viscosity, vazhinji vashandisi vane hanya nezviratidzo zviviri izvi.Iyo yakakwirira iyo hydroxypropyl yemukati, zviri nani kuchengetedza mvura.Viscous, kubata-mvura, zvishoma (panzvimbo ye
6. Chii chakakodzera viscosity yehydroxypropyl methylcellulose (HPMC)?
Mhinduro: Putty powder inowanzoita 100,000 yuan, uye dhaka rinonyanya kudiwa, uye iri nyore kushandisa pa150,000 yuan.Uyezve, basa rakakosha reHPMC nderekuchengeta mvura, zvichiteverwa nekukora.Mune putty powder, chero bedzi kuchengetwa kwemvura kwakanaka uye viscosity yakaderera (70,000-80,000), zvinogonekawo.Ehe, kana viscosity yakakwira, hukama hwekuchengetedza mvura huri nani.Kana iyo viscosity inopfuura 100,000, mhedzisiro yeviscosity pakuchengetedza mvura haina zvakawanda.Absolutely) zvakare zviri nani, uye viscosity yakakwira, uye zviri nani kushandisa mune simende dhaka.
7. Ndezvipi zvinhu zvakakosha zvehydroxypropyl methylcellulose (HPMC)?
Mhinduro: Iyo huru yezvigadzirwa zve hydroxypropyl methylcellulose (HPMC): yakanatswa donje, methyl chloride, propylene oxide, zvimwe zvigadzirwa zvinosanganisira flake alkali, asidhi, toluene, isopropanol, nezvimwe.
