Hydroxypropyl methylcellulose (HPMC) ikamu rinoshandiswa zvakanyanya muindasitiri yekuvaka, kunyanya mumatairi anonamira maumbirwo.Iyi polima inonyungudika mumvura ine huwandu hwakawanda hwezvivakwa, zvichiita kuti ive yakakurumbira musanganiswa mune zvinonamira, machira uye mamwe makemikari ekuvaka.
Nhanganyaya yeHydroxypropyl Methylcellulose (HPMC)
Hydroxypropyl methylcellulose (HPMC) isiri-chepfu, organic, mvura-soluble polymer inoshandiswa zvakanyanya muindasitiri yekuvaka.Inobva kune cellulose, yakasikwa polymer inowanikwa muhuni uye zvimwe zvinomera.HPMC inogadziriswa kemikari nekuwedzera hydroxypropyl uye methyl mapoka kumusana we cellulose, nekudaro inovandudza kuchengetwa kwayo kwemvura, kukora uye kunamatira zvivakwa.
HPMC i polymer inoshanda zvakasiyana-siyana inogona kugadzirwa kune chaiyo chigadzirwa zvinodiwa.Inowanikwa mumagiredhi akasiyana, kubva pasi kusvika pakakwirira viscosity, uye inogona kugadzirwa neakasiyana mazinga ehydroxypropyl uye methyl substitution.Izvi zvinobvumira vagadziri kuti vagadzirise maitiro ekuita kwezvigadzirwa zvavo, zvichiita kuti zvive zvakanyanya kushanda, zviri nyore kushandisa uye zvakachipa kugadzira.
Zvakanakira HPMC mune mataira adhesives
HPMC inoshandiswa zvakanyanya mumatairi adhesive formulations nekuda kwekuwanda kwayo.Hezvino zvimwe zvikonzero nei HPMC iri iyo polymer yesarudzo yekunamatira mataira:
1. Kuchengeta mvura
HPMC inogona kutora uye kuchengetedza yakawanda yemvura, ichiita yakanakisa kuchengetedza mvura mumiriri mumatairi anonamira.Izvi zvakakosha nekuti mvura inobatsira kumisikidza inonamira uye kuisunga kune substrate.NeHPMC, iyo yekunamatira mataira inoramba ichishanda kwenguva yakareba, izvo zvinopa mugadziri nguva yakawanda yekuisa anonamira uye kugadzirisa tile isati yagadzika.
2. Kukora
HPMC chikobvu chinoita kuti mataira anonamira awedzere kuoneka, zvichibatsira kuvandudza simba ravo rekubatana.HPMC inokobvuta kunamira nekuteya mamorekuru emvura, ayo anokobvusa kunamira uye kugadzira inowirirana paste.Izvi zvinoita kuti zvive nyore kuisa chinonamira zvakaenzana uye chinoderedza njodzi yekutsemuka kwemiromo (kureva kusaenzana pakati pematairi).
3. Kuvandudza kunamatira
HPMC inovandudza kusungirirwa kwematairi anonamira nekuda kwekunamatira kwayo.Kana yawedzerwa kune inonamira, HPMC inoumba firimu rakatetepa pamusoro peiyo substrate inobatsira kubatanidza inonamatira kune tile.Iyo firimu inodzivirirawo kunamira kubva pakuoma nekukurumidza, zvichiita kuti irasikirwe nesimba rekubatanidza.
4. Kuchinja-chinja
HPMC inogona kuita kuti mataira anonamira awedzere kuchinjika, izvo zvakakosha munzvimbo dzinofamba nguva zhinji, senge muzvivakwa zvinogara kana kusangana nekudengenyeka kwenyika kana kudengenyeka.HPMC inobatsira kuita kuti chinonamirwa chiwedzere kunyungudika, ichichibvumira kuchinjika uye kufamba nechivakwa, ichidzikisa njodzi yekutsemuka kana kudonha kwematiles.
5. Anti-sag pfuma
HPMC inobatsira kuderedza njodzi yemadziro mataira anonamira sagging.Nekuda kwekukora kwayo zvivakwa, HPMC inobatsira kudzivirira kunamira kubva pakutsvedza kana kudonha kubva pamadziro isati yagadzika.Izvi zvinogona kubatsira vanoisa kuti vakwanise kugadzika tile yekumisikidza uye kuderedza kudiwa kwekugadzirisa zvakare.
mukupedzisa
HPMC i polymer inoshanda zvakasiyana-siyana inopa akawanda mabhenefiti kuindasitiri yekuvaka, kunyanya mumatairi anonamira maumbirwo.Kuchengeta kwayo mvura, kukora, kusunga, kuchinjika uye anti-sag zvivakwa zvinoita kuti ive chinhu chesarudzo pakati pevashandi vekuvaka pasi rese.Nekushandisa HPMC kunyatsogadzirisa maitiro ekuita zvemataira anonamira, vagadziri vanogona kugadzira zvinonamira zviri nyore kuisa, zvine mabhondi akasimba, zvine kuramba kuri nani kutama uye kushorwa kwemvura, uye kashoma kukundikana.Hazvishamisi, saka, kuti HPMC chinhu chakakosha cheindastiri yekuvaka yemazuva ano.
