Muindasitiri yemazuva ano yekupfeka, kuita kwezvakatipoteredza kwave chimwe chezviratidzo zvakakosha zvekuyera kunaka kwekupfeka.Hydroxyethyl cellulose (HEC), seyakajairwa mvura-soluble polymer thickener uye stabilizer, inoshandiswa zvakanyanya mukugadzira machira, latex pendi uye mvura-based coatings. HEC haingonatsiridza mashandiro ekushandisa kwejasi, asi zvakare ine simba rakadzama pane yavo yezvakatipoteredza zvivakwa.
1. Kwakabva uye maitiro eHEC
HEC musanganiswa wepolymer unowanikwa nekugadziriswa kwemakemikari echisikigo cellulose, iyo inoodza uye isina chepfu. Sechinhu chechisikigo, kugadzirwa kwayo uye nzira yekushandisa ine yakaderera kukanganisa nharaunda. HEC inogona kudzikamisa dispersions, kugadzirisa viscosity uye kutonga rheology mumasisitimu ekuputira, ichidzivirira kushandiswa kwemakemikari ekuwedzera ayo anokuvadza kune zvakatipoteredza. Aya maitiro anoisa hwaro hweHEC kuti ive chinhu chakakosha mune zvakatipoteredza zvine hushamwari coating formulations.
2. Optimization yekuputira zvigadzirwa
HEC inoderedza kutsamira pazvinhu zvinosvibisa zvakanyanya nekuvandudza kuita kwekupfeka. Semuenzaniso, mumvura-based coatings, HEC inogona kuvandudza dispersibility ye pigments, kuderedza kudiwa kwezvinogadziriswa-based dispersants, uye kuderedza kubudiswa kwezvinhu zvinokuvadza. Uye zvakare, HEC ine yakanaka solubility yemvura uye munyu kuramba, iyo inogona kubatsira iyo coating kuchengetedza yakatsiga kushanda munzvimbo dzakanyanya kunyorova, izvo zvinoderedza kutadza uye kuparara kwekuputira kunokonzerwa nemamiriro ekunze, nekudaro zvisina kunanga kutsigira kuchengetedzwa kwezvakatipoteredza zvinangwa.
3. VOC kutonga
Volatile organic compounds (VOC) ndiyo imwe yenzvimbo huru dzekusvibisa mumachira echinyakare uye inoisa njodzi inogona kuitika kunharaunda uye hutano hwevanhu. Seyakakora, HEC inogona kunyungudika zvachose mumvura uye inoenderana zvakanyanya nemvura-based coating system, inonyatso kudzikisa kutsamira kune organic solvents uye kuderedza kuburitswa kweVOC kubva kunobva. Kuenzaniswa neyechinyakare thickeners senge silicones kana acrylics, kushandiswa kweHEC kune hushamwari hwakatipoteredza uku uchichengetedza mashandiro ejasi.
4. Kukurudzira budiriro inoenderera mberi
Kushandiswa kweHEC hakungoratidzi kurudziro yezvinhu zvine hushamwari kwezvakatipoteredza, asi zvakare inosimudzira kusimudzira kwakasimba kweindasitiri yekupfeka. Kune rumwe rutivi, sechinhu chakatorwa kubva kune zvinogadziriswazve, kugadzirwa kweHEC kunotsamira zvishoma pamafuta emafuta; kune rumwe rutivi, kushanda kwepamusoro kweHEC mukuputira kunowedzera hupenyu hwebasa rechigadzirwa, nokudaro kuderedza kushandiswa kwezviwanikwa uye kugadzirwa kwemarara. Semuenzaniso, mumapendi ekushongedza, mafomu ane HEC anogona kusimudzira kukwesha uye anti-sagging zvimiro zvepende, zvichiita kuti zvigadzirwa zvinoshandiswa nevatengi zvigare zvakasimba, nekudaro kuderedza kuwanda kwekuvaka kwakadzokororwa uye kuremerwa kwezvakatipoteredza.
5. Matambudziko Ounyanzvi uye Kubudirira Kwemangwana
Kunyangwe HEC ine mabhenefiti akakosha mukuita kwezvakatipoteredza kwependi, kushandiswa kwayo kunotarisanawo nemamwe matambudziko ehunyanzvi. Semuenzaniso, chiyero chekuparara uye kugadzikana kwekuveura kweHEC kunogona kuderedzwa mune mamwe maitiro, uye kushanda kwayo kunoda kuvandudzwa nekuwedzera kuvandudza maitiro. Pamusoro pezvo, nekuramba kusimbaradzwa kwemitemo yezvakatipoteredza, kudiwa kwebio-based ingredients mumapendi kuri kuwedzerawo. Maitiro ekusanganisa HEC nezvimwe zvakasvibirira zvinhu inzira yekutsvagisa ramangwana. Semuenzaniso, kuvandudzwa kweiyo composite system yeHEC nemananomaterials haigone kungowedzera kuvandudza michina yependi, asi zvakare inovandudza antibacterial uye anti-fouling masimba ekusangana nepamusoro pezvakatipoteredza zvinodiwa.
Semushonga wehushamwari wezvakatipoteredza unobva kune yakasikwa cellulose,HECinovandudza zvakanyanya kushanda kwezvakatipoteredza kwepende. Inopa rutsigiro rwakakosha kushanduko yakasvibira yeindasitiri yependi yemazuva ano nekudzikisa kuburitswa kweVOC, kukwenenzvera maumbirwo ependi, uye kutsigira budiriro inoenderera. Kunyangwe mamwe matambudziko ehunyanzvi achiri kuda kukundwa, tarisiro yekushandiswa kwakakura kweHEC mumapendi ane hushamwari kwezvakatipoteredza pasina mubvunzo akanaka uye azere nekugona. Kutarisana nemamiriro ekuwedzera ekuziva kwezvakatipoteredza pasi rose, HEC icharamba ichiwedzera simba rayo kutyaira iyo indasitiri yekupfeka kune remangwana rakasvibira uye rakasimba.
