Paint cleaners anoshandiswa zvakanyanya munzvimbo dzakasiyana siyana dzeindasitiri nedzemumba kubvisa pendi, machira uye zvimwe zvakaoma-ku-kuchenesa zvinhu. Kuti uwedzere kushanda kweaya ekuchenesa, akasiyana emakemikari anounzwa mavari, uye hydroxyethyl cellulose (HEC) chinhu chakakosha chekuwedzera.
Kuongorora kwe hydroxyethyl cellulose
Hydroxyethyl Cellulose (HEC) isiri-ionic mvura-inonyungudika polymer zvinhu zvakawanikwa nekugadziriswa kwemakemikari echisikigo cellulose. Hunhu hwayo hukuru hunosanganisira yakanaka solubility yemvura, yakagadzikana viscosity kugadzirisa kugona, yakanakisa firimu-kugadzira pfuma uye yakasimba thickening mhedzisiro. Aya maitiro anoita kuti HEC ive yakakosha mumhando dzakasiyana dzemaindasitiri ekushandisa, kusanganisira pendi, detergents, cosmetics, zvinodhaka, chikafu nemimwe minda.
Kemikari chimiro che hydroxyethyl cellulose
Iyo yakakosha chimiro cheHEC iketani molecule inoumbwa nekubatanidza β-D-glucose mayunitsi e cellulose kuburikidza ne1,4-glycosidic bond. Iro hydroxyethyl boka rinotsiva chikamu chemapoka ehydroxyl mune cellulose molecule, ichipa iyo yakagadziridzwa solubility uye physicochemical properties. Nekugadzirisa dhigirii rekutsiva uye huremu hwemamorekuru eboka rehydroxyethyl, iyo viscosity uye solubility yeHEC inogona kugadziridzwa, iyo yakakosha pakugadzirisa mashandiro mumashandisirwo akasiyana.
Basa reHydroxyethyl Cellulose muPaint Cleaners
1. Kukora
Rimwe remabasa akanyanya kukosha eHEC nderekukora. Mukuchenesa pendi, HEC inogona kunyatso kuwedzera viscosity yemhinduro. Uku kukora mhedzisiro kunogona kudzivirira iyo yekuchenesa kubva pakumhanya kana yaiswa, nekudaro ichivandudza kusununguka kwayo kwekushandisa uye kushanda. Iko kukora mhedzisiro inobvumirawo muchenesi kuti agadzire jira rakakora panzvimbo yakatwasuka kana yakarerekera, ichirebesa nguva yekuita uye nekunatsiridza maitiro ekuchenesa.
2. Kudzikamisa Kumiswa
HEC inoshandiswawo seyakagadzika mukuchenesa pendi kubatsira kumisa zvisinganyunguriki zvimedu kana zvinhu zvakasimba. Ichi chivakwa chakakosha zvakanyanya kune multiphase masisitimu. HEC inogona kudzivirira sedimentation yezvikamu zvakasimba mukuchenesa, nekudaro kuve nechokwadi chekugadzirisa yunifomu uye inopindirana yekuchenesa maitiro. Uku kudzikamisa kunoenderana netiweki chimiro chakaumbwa neHEC kutora uye kumisa masisitimu akasimba mumhinduro.
3. Kugadzira Mafirimu
HEC ine unhu hwakanaka hwekugadzira firimu, iyo inobvumira muchenesi kuti aite firimu rekudzivirira pamusoro pepamusoro mushure mekushandisa. Iyi firimu inogona kudzivirira detergent kubva pakubuda kana kunyudzwa nekukurumidza panguva yekuchenesa, nekudaro ichiwedzera nguva yekuita uye nekuvandudza maitiro ekuchenesa. Panguva imwecheteyo, iyo firimu-inogadzira pfuma inogonawo kuchengetedza yakacheneswa nzvimbo kubva pakusvibiswa kwechipiri uye kukuvara.
4. Kuzora mafuta
Munguva yekuchenesa maitiro, iyo lubrication yeHEC inobatsira kudzikisa mechanical friction, iyo inonyanya kukosha pakuchenesa nzvimbo dzakaoma. Iyo colloidal mhinduro yakaumbwa nekunyungudika kweHEC mumvura inogona kupa lubrication, kuderedza kupokana pakati pechishandiso chekuchenesa uye pamusoro, uye kuderedza njodzi yekukuvara.
5. Synergist
HEC inogona kushanda pamwe chete nezvimwe zvinongedzo kuti iwedzere kuita kwese kwe detergent. Semuenzaniso, HEC inogona kuvandudza kugovera uye kushanda kwevanoshandisa surfactants mune detergent, nokudaro vachivandudza maitiro ekuchenesa. Mukuwedzera, HEC inogonawo kukanganisa kupararira uye kupindira kwe detergent pamusoro pepamusoro nekugadzirisa rheology yemhinduro, ichiwedzera kuwedzera kukwanisa kwayo kusvibiswa.
Maitiro ekushandisa hydroxyethyl cellulose
1. Dissolution process
Kushandiswa kweHEC mukuchenesa pendi kunowanzotanga nekuparara. Kuparara kwemaitiro kunowanzobatanidza zvishoma nezvishoma kuwedzera HEC poda kumvura pasi pekukurudzira. Kuti udzivise kusangana uye kuve nechokwadi chekupararira kwakafanana, tembiricha yemvura inowanzodzorwa mukati mehumwe huwandu. HEC inonyungudika kuti igadzire yakajeka viscous mhinduro, iyo zvimwe zvinongedzo zvinogona kuwedzera kuwedzerwa sezvinodiwa.
2. Kurongeka kwekuwedzera
Mukugadzirisa kwekuchenesa pendi, kurongeka kweHEC kuwedzera kunogona kukanganisa kushanda kwechigadzirwa chekupedzisira. Inowanzokurudzirwa kuwedzera HEC mushure mokunge zvigadzirwa zvikuru zvakanyungudutswa zvachose kana kusanganiswa zvakafanana. Izvi zvinovimbisa kuti HEC inogona kushandisa zvizere kukora uye kudzikamisa mhedzisiro uku ichideredza zvinogoneka zvinokonzeresa maitiro nezvimwe zvinongedzo.
3. Concentration control
Iko kusungirirwa kweHEC kunokanganisa zvakananga viscosity uye kushandisa mhedzisiro yekuchenesa. Nekugadzirisa huwandu hweHEC, iyo fluidity uye kuwirirana kwekuchenesa kunogona kudzorwa kusangana nezvinodiwa zvakasiyana zvekushandisa. Kazhinji kutaura, kusungirirwa kweHEC mukuchenesa kunotangira kubva ku0.1% kusvika ku2%, zvichienderana nezvinodiwa viscosity uye kuumbwa zvinodiwa.
Zvakanakira zve hydroxyethyl cellulose
1. Kuchengeteka
Sechigadzirwa chakagadziridzwa cheyakasikwa cellulose, HEC ine yakanaka biocompatibility uye kushamwaridzana kwezvakatipoteredza. Kushandiswa kweHEC mukuchenesa pendi hakuzosvibisa nharaunda kana kukonzera njodzi dzehutano kune vashandisi, zvichiita kuti HEC ive yakachengeteka uye isiri-chepfu yekuwedzera.
2. Kugadzikana
HEC inoratidza kugadzikana kwakanaka muhupamhi hwepH uye tembiricha mamiriro uye haakonzeri kukanganisa kana kukundikana. Uku kugadzikana kunovimbisa kuti muchenesi anogona kuchengetedza kuita kwakanaka pasi pekuchengetedza kwakasiyana uye mamiriro ekushandisa.
3. Zveupfumi
Iyo yakaderera mutengo weHEC zvakare chimwe chezvikonzero zvekushandisa kwayo kwakafara. Nekuda kwekuita kwayo kwakanakisa uye mutengo wakaderera, HEC haingopi kuita kwakanakisa mukuchenesa pendi, asiwo ine yakanyanya kudhura-inoshanda.
Kukanganisa kweHydroxyethyl Cellulose
Kunyangwe zvakanakira zvakawanda, HEC zvakare ine zvimwe zvipimo mukushandiswa kwayo mukuchenesa pendi. Semuenzaniso, HEC inogona kuderedza pasi peimwe yakasimba asidhi kana alkaline mamiriro, iyo inomisa kushandiswa kwayo mune mamwe maitiro akakosha. Mukuwedzera, iyo nzira yekuparara kweHEC inoda kunyatsodzorwa kuti irege kuungana uye kupararira kusina kuenzana, zvikasadaro zvinokanganisa kuita kweanochenesa.
Future Development Direction
Nekufambira mberi kwehunyanzvi uye shanduko mukudiwa, kushandiswa kweHEC mukuchenesa pendi kunogona kuwedzera kuwedzerwa. Tsvakurudzo yenguva yemberi inogona kutarisa pane zvinotevera zvinhu:
Kuvandudzwa kwebasa: Kuwedzera kunatsiridza kuita kwe synergistic uye kugadzikana kweHEC kuburikidza nekugadziriswa kwemakemikari kana kusanganisa nezvimwe zvinhu.
Kusimukira kweGreen: Gadzira maitiro ekugadzira ane hushamwari HEC kudzikisa kukanganisa kwezvakatipoteredza uku uchivandudza biodegradability.
Kuwedzera kwechikumbiro: Ongorora mashandisirwo eHEC mune mamwe marudzi e detergents kuti asangane neakasiyana ekuchenesa zvinodiwa, kunyanya mumunda wepamusoro-inodiwa kuchenesa maindasitiri.
Basa rehydroxyethyl cellulose mukuchenesa pendi harigone kufuratirwa. Sezvinoita thickener, stabilizer uye firimu rekare, HEC inovandudza zvakanyanya kushanda kwe detergents uye inoita kuti iite zvakanaka mumashandisirwo akasiyana-siyana. Pasinei nezvimwe zvisingakwanisi, HEC ichine tarisiro yakakura yebudiriro mune ramangwana kuburikidza nekuvandudzwa kwehunyanzvi uye tsvakiridzo yekushandisa. Seyakachengeteka, yakagadzikana uye yehupfumi inowedzera, HEC icharamba ichiita basa rinokosha mumunda wekuchenesa pendi.
