Ndeapi mashandisirwo e hydroxyropropyl methylcellose?
Inoshandiswa zvakanyanya muzvivakwa zvekuvaka, majasi, ceramics, ceramics, mushonga, chikafu, zvinyorwa, zvekurima, zvidhori, zvidhori, fodya uye mamwe maindasitiri. HPMC inogona kukamurwa mu: Giredhi rekuvaka, giredhi rekudya uye giredhi rechiratidzo maererano nechinangwa. Parizvino, yakawanda yezvinhu zvigadzirwa zvemberi ndeyekuvaka giredhi. Mugiredhi rekuvaka, huwandu hweiyo putty poda yakakura kwazvo, inenge 90% inoshandiswa kune putty poda, uye kuzorora kunoshandiswa kune simende dhiri uye glue.
Ndedzipi nzira dzekunyungudika hydroxypruppropyl methyl fiber?
1. Mvura inopisa inonyungudika
2..
Maitiro ekusarudza iyo visikopa yehydroxyropyl methylcellose?
Sarudza akasiyana visikopo zvinoenderana nekushandisa kwakasiyana, kushandiswa kwePutty poda: Unogona kusarudza zvikwangwani zvezviuru zvemazana, chinhu chakakosha ndechekuchengeta mvura iri nani. Kushandiswa kweMoter: Zvakakwirira zvinodiwa, Yakakwira viscosity, sarudza viscosity 150,000. Kushandiswa kweGlue: Unoda zvigadzirwa zvekunze, yakakwira viscosity, sarudza viscosity 200,000.
Maitiro ekuziva hunhu hwe hydroxyprupyl methylcellose?
Whiteeness: Kunyangwe White haisingaone kana HPMC iri nyore kushandisa, uye kana mumiririri akacheneswa achiwedzerwa mukugadzira, ichakanganisa kunaka kwayo. Nekudaro, zvakawanda zvezvigadzirwa zvakanaka zvine machena machena.
Fineness: Iyo yakajeka yeHPMC inowanzoita makumi masere nemateshi uye 100 mesh, uye 120 mesh ishoma. Mazhinji hpmc yakagadzirwa mu hebei is 80 mesh. Iye anokakavara, zviri nani.
Transmittance: Isa HydroxyPropyl methylcellose (HPMC) mumvura kuti ugadzire iyo yakajeka colod colloid, uye tarisa its transmittance. Iko kubvumidzwa kweiyo Vertical Recort Kazhinji, uye iyo inotsanangurwa inowedzera, asi haigone kutaurwa kuti mhando yemutambi wechiitiko iri nani pane iyo yekutsauka, uye pane zvinhu zvakawanda zvinoona maitiro echigadzirwa.
Kunyatso giraira: yakakura iyo chaiyo gravity, inorema zviri nani. Simba renyama rakakura, kazhinji nekuti hydroxyprupropiropropyari mukati mayo yakakwira, uye iyo hydroxyprupropropyl yezviri kumusoro, kuchengetwa kwemvura kuri nani.
Hukama pakati peviscosity uye tembiricha yehydroxyprusyl methylcellose
Iyo viscosity coefficient yeHPMC yakaenzana neiyo tembiricha, kureva kuti tembiricha inoderedza, iyo viscosity coefficient inowedzera, uye iyo 2% mhinduro inoedzwa pakudziya kwemadhigirii makumi maviri celsius. Mune zvinoshandiswa zvinoshanda, munzvimbo dzine mutsauko wakakura wekupisa pakati pezhizha uye chando, zvinofanirwa kucherechedzwa kuti zviso zvakaderera zvinoshandiswa munguva yechando, izvo zvinonyanya kuitwa kuvaka.
Ndeipi basa reHPMC mune putty poda?
MuPutty poda, HPMC inotora zvikamu zvitatu: kururamisa, kudzoreredza kwemvura uye kuvaka.
Kukakavara: Cellulose kunogona kuitwa kuti umise, chengetedza iyo yekugadzirisa yunifomu uye isingachinjiki, uye kuramba sagging.
Kuchengeta kwemvura: Ita iyo POWDY POWDY yakaoma zvishoma nezvishoma, uye ubatsire zvakaitwa neAsh calcium pasi pechiitiko chemvura.
Kuvaka: Cellulose ine mwero unogadzirisa, izvo zvinogona kuita kuti ibwe rekutya riwedzere kushanda zvakanaka. HPMC haitore chikamu mune chero maitiro emakemikari uye anongoita basa rebonde. Kuwedzera mvura kune iyo putty poda uye kuiisa pamadziro maitiro emakemikari. Nekuda kwekuumbwa kwezvinhu zvitsva, tora iyo poro poda pamadziro kubva pamadziro, ichikuya muupfu, uye uishandise zvakare. Izvo hazvizoshande, nekuti zvinhu zvitsva (calcium carbonate) zvakaumbwa. ) kumusoro.
Izvo zvinhu zvikuru zveAsh calcium poda: Ah positi yeCA (OH) 2, CACE CACECATION inogadzirwa, neHPMC chete inochengetedza mvura uye inobatsira iri nani kuita ash Calcium, uye haitore chikamu mune chero maitiro pachawo.
