Iyo cellulose ether hydroxypropylmethylcellulose (HPMC) ndeye multifunctional additive iyo yave chikamu chakakosha chemazuva ano ekuvaka zvinhu. Imwe yeanonyanya kufarirwa maapplication eHPMC ndeyekunamatira mataira. HPMC chinhu chakakosha chekuvandudza chisungo chesimba, kushanda uye kusimba kwematairi anonamira.
Bond simba ndechimwe chezvinhu zvakakosha zvekufunga nezvazvo pakusarudza tile yekunamatira
HPMC inonamira yakanakisa, inoita kuti ive chinhu chakakosha mumatairi anonamira. Inoita seanonamatira nekuzadza gaka pakati pe tile uye substrate. Iyo inovandudza kubatana uye kusimba kwechisungo chekunamatira tile, kuve nechokwadi chisungo chakanaka kune substrate. Nekuda kweizvozvo, matiles haanyanyi kubuda akasununguka, achivimbisa kugadzikana kwenguva refu uye kuderedza zvinodhura kugadzirisa.
Zvivakwa zvekuvaka zvekunamatira tile zvakakosha pakubudirira kwayo.
Inofanira kunge iri nyore kushandisa, kupararira zvakaenzana uye kunamatira kune iyo nzvimbo iyo inoshandiswa. HPMC inobatsira kuvandudza mashandiro ekuvaka ematairi anonamira. Inoshanda semafuta, kudzivirira musanganiswa kubva pakuoma, izvo zvinogona kukonzera kuputika uye kuiswa kusina kuenzana kwematairi. Kushandiswa kweHPMC kunoderedzawo nguva yekusanganiswa inodiwa, kufambisa kushandiswa kwemusanganiswa wekunamatira. Pamusoro pezvo, HPMC inowedzera kugona kweanonamira kubata mvura, ichiibvumira kuti igare zvishoma nezvishoma, ichipa vashandisi nguva yakawanda yekushanda nayo.
Pamusoro pekuvandudza kuvaka, HPMC zvakare inovandudza kuchengetedza kwemvura kweanonamatira mataira
Kuchengetedza hunyoro hwakakodzera hunokosha kuti tile yekunamatira igadzikane. Mvura inobata simba rekunamatira tile inoita basa rakakosha mukuona kuti inogadzika zvakanaka. HPMC inobatsira kuchengetedza mvura, ichibvumira iyo tile yekunamatira kuti ichengetedze kuenderana kwayo kwenguva yakareba. Iyo inonamira ine yakakwirira yekuchengeta mvura uye inoseta zvakaenzana nekuderera kudiki uye kuputika, kuve nechokwadi chekugara uye yakasimba pamusoro.
Kutsemuka uye shrinkage yematairi adhesive matambudziko akajairika kana adhesive kuumbwa kwakashata
HPMC inobatsira kuderedza njodzi yekutsemuka uye shrinkage. Inovandudza kusimba kwechisungo, kushanda uye kuchengetwa kwemvura kwematairi anonamira, anobatsira adhesive seti zvakaenzana uye inoderedza kuputika. Iko kushandiswa kweHPMC kunoderedzawo shrinkage yekunamatira, kuve nechokwadi kuti inoramba ichienderana kwenguva yakareba, ichideredza kudiwa kwekugadzirisa zvakare kunodhura.
Mataira anonamira anofanirwa kuve akasimba, unyoro uye makemikari anopikisa
HPMC ndeye yakanakira yekuwedzera yekunamira mataira sezvo ichiwedzera kemikari nekunyorova kweanonamira. HPMC inoshanda sechidziviriro chinodzivirira, ichigadzira nzvimbo inodzivirira mvura uye inovimbisa hupenyu hurefu hweiyo tile inonamira. Pamusoro pezvo, HPMC inoshingirira kuforoma, fungus uye mabhakitiriya, izvo zvinoita kuti ive yakakodzera kushandiswa mumamiriro ekunyorova.
HPMC chinhu chekuwedzera chakakosha chine mabhenefiti makuru kana ichishandiswa mumatairi anonamira maumbirwo
Sezvakakurukurwa, mabhenefiti ayo anosanganisira kuvandudzwa kwechisungo simba, processability uye kusimba kweanonamatira. Inovandudza kuchengetwa kwemvura, inoderedza kuputika uye shrinkage, ichiwedzera kupikisa kwayo kune unyoro, mold, fungus uye mabhakitiriya. Aya mabhenefiti anoita kuti ive chinhu chakakosha mumatairi adhesives, kushandiswa kwayo kunogona kuvandudza zvakanyanya kunaka kwechigadzirwa chakapedzwa. Naizvozvo, zvakakosha kugadzirira cellulose ether HPMC mumatairi anonamira kuti ipe kuita kwakanyanya.
