4 Mibvunzo nezve HPMC

1. Ndezvipi zvinoshandiswa zvakanyanya zvehydroxypropyl methylcellulose (HPMC)?
HPMC inoshandiswa zvakanyanya mukuvaka, machira, ekugadzira resin, ceramics, mishonga, chikafu, machira, kurima, zvizorwa, fodya uye mamwe maindasitiri.HPMC inogona kukamurwa kuita giredhi rekuvaka, chikafu giredhi uye giredhi remishonga zvinoenderana nekushandiswa kwayo.Parizvino, kugadzirwa kwakawanda kweChinese mudzimba kuri padanho rekuvaka.Padanho rekuvaka, putty poda inoshandiswa muhuwandu hwakawanda, ingangoita 90% yeputty poda uye imwe yesamende dhaka uye mataira adhesive.

2. Ndezvipi zvikonzero zvekuputika muputty powder panguva yekushandiswa kweHPMC mune putty powder?
HPMC inoita seyakakora, inochengetedza mvura uye muvaki mune putty hupfu.Hazvina kubatanidzwa mune chero maitiro.

Zvinokonzera kutumbuka: 1. Mvura yakawandisa.2. Musoro wepasi hauna kuoma, ingotsvaira mutsara pamusoro pepamusoro, iyo inoputikawo nyore nyore.

3. Ndeapi marudzi ehydroxypropyl methylcellulose (HPMC) aripo?Ndeupi musiyano uripo pakati pavo?
HPMC inogona kukamurwa kuita pakarepo uye inopisa soluble.Pakarepo soluble zvigadzirwa, bvisa nekukurumidza uye kunyangarika mumvura mumvura inotonhora.Panguva ino, mvura haina viscosity sezvo HPMC inongopararira mumvura uye isinganyungudika.Mushure memaminitsi maviri, viscosity yemvura inowedzera zvishoma nezvishoma, ichigadzira gel yakajeka.Iyo inopisa soluble chigadzirwa inogona kupararira nekukurumidza mumvura inopisa uye inonyangarika mumvura inopisa.Sezvo tembiricha inodonha kune imwe tembiricha, iyo viscosity inooneka zvishoma nezvishoma kusvikira yakajeka viscous gel inoumbwa.

Iyo inopisa yakanyunguduka mhando inogona kungoshandiswa mumaputty poda uye dhaka.Mumvura glues uye pendi, caking inoitika uye haigone kushandiswa.Rudzi rwepakarepo rune huwandu hwakasiyana hwekushandisa uye hunogona kushandiswa mune putty hupfu uye dhaka pamwe chete mune yemvura glues uye pendi.

4. Hunhu hwehydroxypropyl methylcellulose (HPMC) hunogona kutsanangurwa sei zviri nyore uye nekuona?
(1) Simba rinokwevera zvinhu pasi: Kukwirira kwesimba rinokwevera zvinhu pasi, ndikowo kunaka kwemhando.
(2) Kuchena: Zvigadzirwa zvemhando yepamusoro zvine kuchena kwakanaka.Kunze kweavo vane akawedzera whitening agents.Whitening agents anogona kukanganisa kunaka.
(3) Kunaka: Kana kunaka kwacho kunowedzera, ndikowo kunaka kwacho.Iko kunaka kweHPMC yedu kunowanzo 80 mesh uye zana mesh, 120 mesh inowanikwawo.
(4) Transmittance: Isa HPMC mumvura kuti igadzire gel inoonekera uye tarisa kutapurirana kwayo.Iyo yakakura iyo transmittance, zvishoma zvisinganyunguriki zvinhu.Vertical reactors kazhinji ane zvirinani transmittance uye horizontal reactors haana kutapurirana kwakashata, asi izvi hazvireve kuti mhando yekugadzira yemareactors yakatwasuka iri nani pane yedzimwe nzira dzekugadzira.Pane zvinhu zvakawanda zvinotarisa kunaka kwechigadzirwa mumareactors akaenzana, ane high hydroxypropyl content uye high hydroxypropyl content, iyo yakanakisisa yekuchengetedza mvura.
