Hydroxyethyl methylcellulose (HEMC)imhando ye cellulose ether isingashandisi ionic inoshandiswa zvakanyanya mumaindasitiri mazhinji. Iupfu huchena kana husina kuchena hwakagadzirwa nezvinhu zvechisikigo zvepolymer - donje rakanatswa kuburikidza nemakemikari akadai sealkalizing uye etherification. Ine mvura inonyunguduka zvakanaka, inochengetedza mvura, inoita firimu, inoita kuti iwedzere kukora, inosimbisa uye inogadzikana.
1. Kushandiswa muindasitiri yekuvaka
Hydroxyethyl methylcellulose inoshandiswa zvakanyanya muindasitiri yekuvaka, kunyanya muzvigadzirwa zvemortar zvakasanganiswa zvakaoma, izvo zvinonyanya kuratidzwa muzvinhu zvinotevera:
Kuchengetwa kwemvura kwakasimba: Mushure mekuwedzera HEMC mumota yesimbi kana zvigadzirwa zvegypsum, mashandiro ayo ekuchengetedza mvura anogona kuvandudzwa zvakanyanya, kudzivirira kurasikirwa nemvura zvakanyanya, kukurudzira kunyorova kwesimbi, uye kuwedzera kunamira uye kusimba.
Kuvandudza mashandiro ekuvaka: HEMC inogona kuvandudza kunyorova uye kushanda zvakanaka kwedhaka, kuita kuti kupurasita, kuisa zvidhinha nezvimwe zvinhu zvive nyore, kuderedza kunamira kwezvishandiso, uye kuvandudza kushanda zvakanaka kwekuvaka.
Hunhu hunodzivirira kudonha: Muzvigadzirwa zvekuvaka zvakamira zvakaita se tile adhesive ne putty powder, HEMC inogona kuwedzera zvakanyanya hunhu hwayo hwekudzivirira kudonha uye kudzivirira zvinhu kuti zvisayerera panguva yekuvaka.
Kukora: HEMC inogona kuwedzera kusimba kwedhaka, zvichiita kuti zvive nyore kunamira pamusoro pe substrate, zvichiwedzera kunaka kwekuputira uye slurry.
Kuvandudza nguva yekushanda: Wedzera nguva yekuvhura, vandudza kuchinjika kwekushanda, uye batsira kugadzirisa kuvaka.
Zvigadzirwa zvinoshandiswa zvakanyanya zvinosanganisira: kunamira mataira, dhaka rekudzivirira madziro ekunze, upfu hweputty, dhaka rekupurasita, dhaka rinozvienzanisa, dhaka rakasanganiswa rakaoma, nezvimwewo.
2. Kushandiswa muindasitiri yekuputira
Muindasitiri yekupenda nekupenda, hydroxyethyl methyl cellulose inoshandiswa sechinhu chinosimbisa, chinosanganisa, chinoparadzira uye chinoita kuti firimu riwedzere. Mabasa ayo ndeaya anotevera:
Kukora uye kugadzikana: HEMC inogona kuwedzera kunaka kwependi yelatex, kudzivirira kunaya kwepigment, uye kugadzirisa kugadzikana kwekuchengetedza.
Kuvandudza mashandiro ekukwesha: Kuvandudza mashandiro ekukwesha, kutenderedza kana kupfapfaidza pendi, zvichiita kuti kuvakwa kwayo kuve kwakapfava uye kuderedza kupfapfaidza nekudonhedza mvura.
Kuchengetwa kwemvura uye kugadzirwa kwefirimu: Kuchengetedza hunyoro pamusoro pepende kunobatsira pakuumbwa kwefirimu uye kunatsiridza kufanana uye kutsetseka kwefirimu repende.
Kugadzikana kwakanaka kwepH: HEMC inogona kuvapo zvakanaka muhuwandu hwakakura hwepH (3~11) uye yakakodzera kune akasiyana masisitimu ependi.
Saka, HEMC inoshandiswa mumapendi ane mvura akadai sependi dzemukati nekunze dze latex pamadziro, pendi dzemumaindasitiri dzine mvura, uye pendi dzehuni.
3. Kushandiswa muzvigadzirwa zvemakemikari zvezuva nezuva
Hydroxyethyl methylcellulose inoshandiswa zvakanyanya muzvigadzirwa zvemazuva ese zvemakemikari zvakaita seshampoo, shower gel, toothpaste, uye zvigadzirwa zvekuchengetedza ganda. Mabasa ayo makuru ndeaya:
Chinokora: Wedzera kunaka kwezvigadzirwa zvemvura uye kuvandudza ruzivo rwechigadzirwa.
Kubatanidza uye kumisa: Kusimbisa sisitimu ye emulsion, kudzivirira kupatsanurwa kwechikamu chemafuta nechikamu chemvura, uye kuita kuti paste igadzikane uye ifanane.
Kunyorovesa: Inobatsira kuchengetedza mvura zvakanaka, inodzivirira kubuda kwemvura paganda kana bvudzi, uye inowedzera mafuta.
Kunyorova kwakanaka: HEMC icellulose isiri ionic isingatsamwise ganda uye yakakodzera ganda rinonzwa kurwadza uye zvigadzirwa zvevana.
4. Kushandiswa muindasitiri yemishonga neyekudya
Kunyangwe kushandiswa kukuru kweHEMC kwakanyanya kushandiswa mumaindasitiri, HEMC inogona kushandiswawo mumaindasitiri emishonga nechikafu pasi pezvimwe zvinodiwa.
Zvinhu zvinobatsira pakurapa: HEMC inoshandiswa semushonga unosunga, unofukidza firimu uye unoburitsa mapiritsi kwenguva refu kuti udzore huwandu hwemishonga inoburitswa.
Zvinowedzerwa muchikafu: Mune dzimwe nyika/nzvimbo, HEMC inotenderwa kushandiswa sechinhu chinosimbisa chikafu, chinosanganisa chikafu uye chinosimbisa chikafu, senge muzvikafu zvakachengetwa mufiriji, masiwiti, zvinonhuhwirira, nezvimwewo.
Zvinhu zvekufukidza zvinoburitswa kwenguva refu: HEMC inoshandiswa kugadzira mishonga inoburitswa kwenguva refu, uye hunhu hwayo hwekugadzira firimu hunodzora nguva yekuburitswa kwemishonga uye mwero wemishonga mudumbu.
5. Kushandiswa mune mamwe maindasitiri
Kuboora oiri: HEMC inoshandiswa senzira yekuderedza uye kuomesa muboora mvura kuti ivandudze kugadzikana kweboora nemvura uye kuderedza kurasikirwa kwemvura.
Indasitiri yekugadzira mapepa: HEMC inogona kushandiswa pakugadzirisa pamusoro pemapepa kuti iwedzere kupfava, kuramba mafuta uye kudhindwa kwayo.
Indasitiri yemachira: Inoshandiswa sedhiringi uye dhayi kuti machira akwanise kukura zvakanaka uye kuwachiswa zvakanaka.
Indasitiri yeCeramic: Munguva yekugadzira ceramic, HEMC inowedzera simba remuviri wegirini uye inovandudza kufanana kweglazing.
Hydroxyethyl methylcellulosei cellulose ether inoshanda zvakasiyana-siyana ine mashandiro akanaka uye inoshandiswa zvakanyanya. Kukora kwayo, kuchengetedza mvura, kugadzira mafirimu, emulsifying nezvimwe zvinhu zvinoita kuti ive nechinzvimbo chakakosha mumaindasitiri akawanda akadai sekuvaka, machira, makemikari ezuva nezuva, mishonga, uye chikafu. Nekufambira mberi kwekuchengetedzwa kwezvakatipoteredza kwakasvibirira uye pfungwa dzekusimudzira nharaunda, HEMC, sechinhu chinobatsira zvakatipoteredza chinobva mufiber yechisikigo, inotarisirwa kuramba ichiwedzera kudiwa kwayo kwemusika nenzvimbo dzekushandisa.
