Hydroxypropyl Methylcellulose sevanoparadzanisa vamiririri, zvigadzirwa zvakawanikwa zvine zvakarongeka uye zvakasununguka zvimedu, zvakakodzera zvinooneka density uye kuita kwakanakisa kugadzirisa.Nekudaro, kushandiswa kweHydroxypropyl Methylcellulose chete kunogona kubatsira mukusawirirana kwakanaka kweresin.Kushanda kwese kweresin kwakashata.Iko kushandiswa kwemubatanidzwa kwehydroxypropyl methylcellulose uye akati wandei akasiyana alcoholysis degree yepolyvinyl doro inogona kuita kuti mashandiro ezvigadzirwa zvive nani, mhando iri nyore kudzora uye panguva imwe chete inogona kuderedza mutengo.Iyo inoparadzira mumiriri ndicho chinhu chikuru chinokanganisa chimiro chepolyvinyl chloride resin.Iyo idiki iyo kushushikana kwepamusoro kweiyo aqueous mhinduro yeakawanda anoparadzira maajenti uye kupindirana kwechiso neVinyl chloride monomer ndiko, kunonakisa madonhwe eVCM anogona kuparadzirwa.Uye saka iyo chidimbu dhayamita yePVC resin ichave idiki.Iyo yakasimba simba rekudzivirira yeanoparadzira mumiriri ndeye, padyo neiyo inowanikwa PVC resin particles ichave uye idiki iyo porosity ichave.Uye intergranular coalescence zvakare yakaoma, saka zviri nyore kugadzira resins.
Semuyenzaniso, mucompound dispersion system yePVA neHPC, iyo yakakwira iyo alcoholysis degree yePVA iri, iyo yakanyanya kusimba pamusoro pemushonga wemvura inoyerera uye kusimba kwesimba rekudzivirira kunenge kuri, nepo imwe denderedzwa yehydroxypropyl methylcellulose ine. kuita zvakanaka kwekuparadzira.Naizvozvo, kushandisa PVA ine yakakwira alcoholysis degree seyekutanga
chinoparadzira, uye kusanganisa a
humwe huwandu hwehydroxypropyl methylcellulose
seanoparadzira mumiriri wekumiswa kwepolymerization, zviri nyore kugadzirira iyo PVC resin inogona kusangana nezvinodiwa zvechidimbu morphology.Semuyenzaniso, mucompound dispersion system yePVA neHPC, iyo yakakwira iyo alcoholysis degree yePVA iri, iyo yakanyanya kusimba pamusoro pemushonga wemvura inoyerera uye kusimba kwesimba rekudzivirira kunenge kuri, nepo imwe denderedzwa yehydroxypropyl methylcellulose ine. kuita zvakanaka kwekuparadzira.
