Hydroxypropylmethylcellulose (HPMC) is a cellulose ether inotorwa kubva kune yakasikwa cellulose. HPMC inoshandiswa mumhando dzakasiyana siyana dzekushandisa dzinosanganisira kugadzira chikafu, kuvaka, mishonga yemishonga uye zvekuzora. Semugadziri weHPMC, takazvipira kugadzira zvigadzirwa zvemhando yepamusoro zvinosangana nezvinodiwa nevatengi vedu.
Mumakore achangopfuura, yakaderera-viscosity HPMC yakawedzera kufarirwa muindasitiri yekuvaka nekuda kwekuvandudzwa kwayo kwekushandisa zvivakwa uye zviri nani kuparadzira zvivakwa. Low-viscosity HPMC inowanzoshandiswa mumadhaka, plasters uye mataira anonamira seanokora, bhainda uye anochengetedza mvura. Muchikamu chino, tinotsanangura yakaderera viscosity HPMC uye mabhenefiti ayo eindastiri yekuvaka.
Chii chinonzi low viscosity HPMC?
Low Viscosity HPMC is a cellulose ether ine yakaderera viscosity zvichienzaniswa netsika HPMC. Izvi zvinoita kuti kubata uye kugovera kuve nyore, uye zvakare kunovandudza kushanda kwezvinhu zvekuvaka. Yakaderera-viscosity HPMC inowanzoshandiswa mudhaka uye zvimwe zvekuvaka kuita seyakakora uye kunatsiridza kubatana kwechinhu uye kushanda.
Ndezvipi zvakanakira yakaderera viscosity HPMC?
Kuvandudzwa Kwekushanda: Yakaderera viscosity HPMC inovandudza kushanda kwezvinhu zvekuvaka nekuvandudza kuyerera uye kupararira kwezvinhu. Izvi zvinoita kuti application ive nyore uye inovandudza huwandu hwese hwechigadzirwa chakapedzwa.
Zvirinani Adhesion: Yakaderera-viscosity HPMC inoita seanonamira kuvandudza kunamatira kwezvinhu zvekuvaka kune substrates. Izvi zvinoita kuti ive yakanaka yekuwedzera kune dhaka, plasters uye mataira anonamira.
Kunatsiridza kuchengetedza kwemvura: Yakaderera viscosity HPMC inogona zvakare kuwedzera kuchengetwa kwemvura mune zvekuvaka, kuderedza huwandu hwemvura inodiwa kuti uwane inodiwa kushanda. Izvi zvinochengetedza mari uye zvinovandudza mashandiro echigadzirwa.
Isiri-chepfu uye ine hushamwari kwezvakatipoteredza: yakaderera-viscosity HPMC haina chepfu uye inoshamwaridzana nenharaunda, uye isarudzo yakachengeteka yezvinhu zvekuvaka. Iyo zvakare ine biodegradable uye inogona kushandiswa zvakare nyore.
Wide Range of Applications: Low-viscosity HPMC inogona kushandiswa mune zvakasiyana-siyana zvekuvaka, zvinosanganisira madhaka, plasters, grouts uye mataira anonamira. Inoshandiswawo mukugadzirwa kwemishonga, cosmetic uye chikafu.
Ko yakaderera viscosity HPMC inogadzirwa sei?
Low viscosity HPMC inogadzirwa uchishandisa maitiro akafanana neyechinyakare HPMC. Maitiro acho anosanganisira kushandura yemuno selulosi kuita methylcellulose, wobva wawedzera hydroxypropyl mapoka kune methylcellulose kuumba HPMC. Low viscosity HPMC inogadzirwa nekudzora dhigirii rekutsiva (DS) uye molecular huremu hweHPMC, zvichikonzera yakaderera viscosity chigadzirwa.
Ndeapi marudzi eyakaderera viscosity HPMC aripo?
Low viscosity HPMC inowanikwa mumhando dzakasiyana dzemagiredhi, imwe neimwe iine zvimiro zvayo uye maitiro. Mamwe akajairika akaderera viscosity HPMC marudzi anosanganisira:
- LV: yakaderera viscosity giredhi ine viscosity renji ye50 - 400 mPa.s. LV HPMC inowanzoshandiswa mumapurasita, madhaka uye zvinonamira mataira.
- LVF: yakaderera viscosity inokurumidza kuseta giredhi ine viscosity renji ye50 - 400 mPa.s. LVF HPMC inowanzoshandiswa mukukurumidza kuseta mataira anonamira uye grouts.
- LVT: Yakaderera viscosity thickening giredhi ine viscosity renji ye400 - 2000 mPa.s. LVT HPMC inowanzoshandiswa mumakomisheni akabatana, kudhinda machira uye zvigadzirwa zvekuchengeta munhu.
Ndeapi mashandisirwo eyakaderera viscosity HPMC?
Yakaderera viscosity HPMC inoshandiswa zvakanyanya muindasitiri yekuvaka seyakakora, inonamira uye inochengetedza mvura mumiriri. Mamwe maapplication akajairika eyakaderera viscosity HPMC mukuvaka anosanganisira:
- Mota: Yakaderera viscosity HPMC inoshandiswa mumadhaka kuvandudza kushanda, kunamatira uye kuchengetedza mvura. Iyo zvakare inokora dhaka, zvichiita kuti zvive nyore kuisa uye kuderedza njodzi yekutsemuka.
-Plastering: Yakaderera viscosity HPMC inoshandiswa mukupurasita kuvandudza kushanda uye kuchengetwa kwemvura. Inonatsiridzawo chitarisiko cheshanduro dzako, ichiita kuti nzvimbo dzadzo dzive dzakapfava.
- Tile Adhesives: Yakaderera viscosity HPMC inoshandiswa mumatairi anonamira kuvandudza kushanda, kunamatira uye kuchengetedza mvura. Iyo zvakare inovimbisa kuti iyo tile yekunamatira inoramba ichichinjika mushure mekunge yagadzika.
- Grouting: Yakaderera viscosity HPMC inoshandiswa mukugadzika kuvandudza kushanda uye kuchengetedza mvura. Inobatsirawo kudzivirira grout kubva pakutsemuka nekuderera.
mukupedzisa
Yakaderera-viscosity HPMC chinhu chakakosha chekuwedzera muindasitiri yekuvaka, iyo inogona kuvandudza kushanda, kunamatira uye kuchengetwa kwemvura kwezvinhu zvekuvaka. Semugadziri weHPMC, takazvipira kugadzira zvigadzirwa zvemhando yepamusoro zvinosangana nezvinodiwa nevatengi vedu. Tichaenderera mberi nekuvandudza nekuvandudza zvigadzirwa zvedu kuti tive nechokwadi chekuti zvinoramba zviri pamberi peindastiri yekuvaka.
