Hydroxypropylmethylcellulose (HPMC) i polymer yekugadzira inoshandiswa mumaindasitiri akasiyana siyana anosanganisira emishonga, zvekuzora nekuvaka. Iyo isiri-chepfu uye biodegradable komboni ine yakanakisa kuchengetedza mvura. Nekudaro, mune mamwe maapplication, HPMC inogona kuratidza yakawandisa kuchengetwa kwemvura, izvo zvinogona kunetsa. Muchikamu chino, tinokurukura zvikonzero zvina zvikuru nei HPMC ichichengeta mvura uye dzimwe nzira dzinogona kugadzirisa dambudziko.
1. Particle size uye dhigirii yekutsiva
Chimwe chezvinhu zvinonyanya kukosha zvinokanganisa kuchengetwa kwemvura kweHPMC ihukuru hwayo uye dhigirii rekutsiva (DS). Kune akasiyana mamakisi eHPMC, imwe neimwe iine chaiyo DS uye particle size. Kazhinji kutaura, kukwirisa dhigirii rekutsiva HPMC, ndiko kukwira kwesimba rekuchengetedza mvura. Nekudaro, izvi zvinotungamira kune yakakwira viscosity, iyo inokanganisa processability kune mamwe maapplication.
Saizvozvo, saizi yechikamu inokanganisawo kuchengetwa kwemvura kweHPMC. Diki particle size HPMC ichava nenzvimbo yepamusoro yepamusoro inogona kuchengetedza mvura yakawanda, zvichikonzera kuchengetwa kwemvura kwakakwirira. Nekune rimwe divi, hukuru hukuru hukuru hweHPMC hunobvumira kupararira kuri nani uye kusanganisa, zvichikonzera kugadzikana kuri nani pasina kukosha kwekuchengetedza mvura.
Zvinogoneka mhinduro: Kusarudza giredhi rakakodzera reHPMC ine yakaderera dhigirii yekutsiva uye yakakura particle size inogona kuderedza kuchengetwa kwemvura pasina kukanganisa kushanda kwechikumbiro.
2. Mamiriro ezvakatipoteredza
Mamiriro ekunze akadai sekushisa uye humidity anogona zvakare kukanganisa zvakanyanya kuchengetwa kwemvura kweHPMC. HPMC inogona kutora uye kuchengetedza hunyoro kubva kune yakatenderedza nharaunda, izvo zvinogona kutungamirira kune yakawandisa kuchengetwa kwemvura kana kunonoka kuoma. Tembiricha yakakwira inomhanyisa kunyura nekuchengeta mwando, ukuwo tembiricha yakaderera ichinonoka kuomeswa, zvichikonzera kuchengetedza mwando. Saizvozvowo, nzvimbo dzakanyanya hunyoro dzinogona kukonzera kuwandisa kwemvura kuchengetedza uye kunyangwe kudzoreredzwa kweHPMC.
Zvinogoneka mhinduro: Kudzora mamiriro ezvakatipoteredza umo HPMC inoshandiswa inogona kuderedza zvakanyanya kuchengetedza kwemvura. Semuenzaniso, kushandisa dehumidifier kana air conditioner kunogona kuderedza humidity ambient, nepo kushandisa feni kana hita kunogona kuwedzera mhepo uye kuderedza nguva inotora HPMC kuoma.
3. Mixed processing
Iko kusanganiswa uye kugadzirisa kweHPMC kunogonawo kukanganisa maitiro ayo ekuchengetedza mvura. Iyo HPMC yakasanganiswa uye kugadziriswa sei inogona kuona iyo mvura inobata simba uye dhigirii re hydration. Kusakwana kusanganiswa kweHPMC kunogona kukonzera clumping kana makeke, izvo zvinokanganisa kubata kwemvura. Saizvozvo, kunyanya-kusanganisa kana kuwedzeredza-kugadziridza kunogona kukonzera kuderedzwa kwechikamu saizi, izvo zvinowedzera kuchengetwa kwemvura.
Zvinogoneka Solutions: Kusanganiswa kwakakodzera uye kugadzirisa kunogona kuderedza zvakanyanya kuchengetedza kwemvura. HPMC inofanirwa kusanganiswa kana kusanganiswa zvakakwana kuti ive nechokwadi chekugoverwa kwakafanana uye kudzivirira kuumbwa kwemapundu kana mapundu. Kuwedzeredza kunofanirwa kudziviswa uye kugadzirisa mamiriro akanyatso kudzorwa.
4. Formula
Chekupedzisira, kuumbwa kweHPMC kunokanganisawo zvimiro zvayo zvekuchengetedza mvura. HPMC inowanzoshandiswa pamwe chete nezvimwe zvinowedzera, uye kuenderana kwezvinowedzera izvi kuchakanganisa kuchengetwa kwemvura kweHPMC. Semuenzaniso, mamwe makobvu kana ma surfactants anogona kudyidzana neHPMC uye kuwedzera simba rayo rekubata mvura. Kune rimwe divi, mamwe mainorganic salts kana acids anogona kuderedza simba rekubata mvura nekudzivirira kuumbwa kwehydrogen bond.
Zvinogoneka mhinduro: Kunyatsogadzira uye kusarudzwa kwezvinowedzera zvinogona kuderedza zvakanyanya kuchengetwa kwemvura. Kugarisana pakati peHPMC nezvimwe zvinowedzerwa zvinofanirwa kunyatsotariswa uye kukanganisa kwavo pakuchengetedza mvura kuongororwa. Kusarudza zvinowedzera zvine simba shoma pakuchengetedza mvura inogona kuva nzira inoshanda yekuderedza kuchengetwa kwemvura.
mukupedzisa
Mukupedzisa, HPMC yave yakakosha polima mumaindasitiri akasiyana nekuda kwekunaka kwayo kuchengetedza mvura. Nekudaro, kune mamwe maapplication, yakawandisa kuchengetwa kwemvura kunogona kunetsa. Nekunzwisisa zvinhu zvinokanganisa kuchengetedza kwemvura uye kushandisa mhinduro dzakakodzera, kuchengetwa kwemvura kweHPMC kunogona kuderedzwa zvakanyanya pasina kukanganisa kushanda.
