4. Hydroxyprusyl methylcellose (HPMC) nzira yekudzvinyirira:
Kana hydroxyprupylpropyl methylcellose (HPMC) zvigadzirwa zvinowedzerwa zvakananga nemvura, ivo vachatora uye vanobva vanyungudika, asi kupaza uku kunononoka uye kwakaoma. Pane nzira nhatu dzakakurudzirwa dzakaputswa pasi apa, uye vashandisi vanogona kusarudza nzira yakanyanya nyore maererano nekushandisa kwavo:
1. Mvura inopisa nzira: Kubva hydroxypropyl methylcellose (HPMC) haina kuparadzaniswa nemvura inopisa (HPMC) inogona kutapurwa nemvura inopisa, uye kana ichinge yapetwa, nhatu imwe nzira inotsanangurwa se Inotevera:
1). Isa huwandu hunodiwa hwemvura inopisa mumudziyo uye uzvidzise kusvika pamakore makumi manomwe c. Zvishoma nezvishoma Wedzera HydroxyPropyl methylcellose (HPMC) Inononoka Kukurudzira, Iyo HPMC) inotanga kuyerera pamusoro pemvura, uyezve zvishoma nezvishoma inoumba slurry, inotonhorera iyo slurry pasi pekumutsa.
2). Kupisa 1/3 kana 2/3 (inodiwa huwandu) yemvura mumudziyo uye kupisa iyo kusvika pamakumi manomwe c. Maererano nenzira ye1), kuparadzira hydroxypressl methylcellose (HPMC) yekuwedzera iyo yasara yemvura, wobva wawedzera iyo hydroxproproproproproplose (HPMC) mvura inopisa slurry kune iyo mvura inotonhora, uye kumutsa, uye wozotonhorera musanganiswa.
3). Wedzera 1/3 kana 2/3 yehuwandu hunodiwa hwemvura mumudziyo uye uzvidzise kusvika pamakumi manomwe c. Sekureva kwenzira ye1), kuparadzira hydroxyprupyl methylcellose (HPMC) kugadzirira mvura inopisa slurry; Mari yakasara yechando kana yechando mvura inowedzerwa kune inopisa mvura slurry uye musanganiswa wacho wakatonhorera mushure mekukurudzira.
2.. . 3. Organic solvent yekunyaradza nzira: pre-kupararira kana yakanyorova hydroxpremyl methylcellose (HPMC) ine organic sol, ethylene glycol kana mafuta, obva azvinyima mumvura. Panguva ino, hydroxyprupyl methylcellose (HPMC) inogona zvakare kunyungudutswa zvakanaka.
5. Kushandiswa kukuru kwehydroxyprupyl methylcellose (HPMC):
HydroxyPropyl methylcellose (HPMC) inogona kushandiswa seanotenderedza, inoparadzira, emulsifier uye firimu-inogadzira mumiririri. Zvigadzirwa zvayo zvegiredhi-giredhi zvinogona kushandiswa mumakemikari ezuva nezuva, zvemagetsi, zvigadziko zvekugadzira, kuvaka uye huviri.
1. Kumiswa Polymerization:
Mukugadzirwa kweiyo synthetic nzvimbo dzakadai saPolyvinyl chloride (PVC), Polyvinylidene chloride chloride chloride chloride chloride chloride Semvura-ye-myruxpremypropyl methylcellose (HPMC) zvigadzirwa zvine chekuita neyekudzivirira kwemumiriri uye kuita zvinobudirira kudzivirira kuunganidzwa kwePolymer zvikamu zvePolymer. Uyezve, kunyangwe hydroxyprightlmellose (HPMC) ndeye poldu-soluble polymer yemvura uye inowedzera porosekishi kubva kune iyo polymerics inogadzirwa, kuitira kuti inogona kupa polymers nekugona kwakanakisa kubvisa kusara kwemasere uye kusimudzira kwekunyora kwepurasitiki.
2. Mukuumbwa kwezvinhu zvekuvaka, hydroxyprusyl methylcellose (HPMC) inogona kushandiswa:
1). Kunamatira uye kunyengedza mumiririri weGypsum-based adishive tepi;
2). Kusungwa kwezvidhinha zve coment-basement, matairi nenheyo;
3). Plasterboard-based stucco;
4). Simende-yakavakirwa chivakwa plaster;
5). Mune formula yekupenda uye pendi remover.
