Sipo yeLiquid inogoneka uye inoshandiswa zvakanyanya yekuchenesa mumiriri inokosheswa nekureruka kwayo uye kushanda kwayo.Nekudaro, mune dzimwe nguva, vashandisi vangangoda kusimba kwakasimba kwekuvandudza kuita uye kushandisa.Hydroxyethylcellulose (HEC) yakakurumbira thickening agent inoshandiswa kuwana yaidiwa viscosity mukugadzira sipo yemvura.
Dzidza nezve Hydroxyethyl Cellulose (HEC):
Kemikari chimiro uye zvivakwa:
HEC ipolymer inonyungudika nemvura inotorwa kubva ku cellulose, polima yemusikirwo inowanikwa mumadziro esero.
Chimiro chayo chemakemikari chinosanganisira cellulose musana nemapoka e-hydroxyethyl, zvichiita kuti zvive zvakanyanya kunyunguduka mumvura uye inoenderana nemhando dzakasiyana-siyana.
thickening mechanism:
HEC inokora zvinwiwa nekuwedzera viscosity kuburikidza nekuchengetedza mvura uye firimu-kugadzira zvivakwa.
Iyo inoumba matatu-dimensional network mumvura, ichigadzira gel-senge chimiro chinosimudzira kuenderana kwezvinwiwa.
Kuenderana ne surfactants:
HEC ine kuenderana kwakanaka nemasurfactants anowanzo shandiswa mukugadzira sipo yemvura.
Kugadzikana kwayo muhupo hwemakemikari akasiyana-siyana kunoita kuti ive yakanakira kukora sipo zvigadzirwa.
Zvinhu zvinokanganisa kukora sipo:
Sipo resipi:
Izvo zvakakosha kuti unzwisise zvakakosha zvesipo yemvura.Kuvapo kwemamwe maion, pH, uye zvimwe zvikamu zvinogona kukanganisa HEC kuita.
Inodiwa viscosity:
Chiratidzo chakajeka chinotsanangurwa viscosity chakakosha pakusarudza kusungirirwa kwakakodzera kweHEC kushandiswa.
tembiricha:
Kupisa panguva yekugadzira kunokanganisa kupera uye kushandiswa kweHEC.Inogona kuda kugadziriswa kunoenderana nekushisa kwekushanda.
Kubatanidza HEC mune yekubika sipo yemvura:
Zvishandiso nemidziyo:
Unganidza izvo zvinodiwa zvinosanganisira sipo yemvura base, HEC hupfu, mvura, uye chero zvimwe zvinowedzera.
Yakashongedzerwa nemudziyo wekusanganisa, stirrer uye pH mita.
Kugadzirira kweHEC mhinduro:
Weresa huwandu hunodiwa hweHEC hupfu hunoenderana neinoda viscosity.
Zvishoma nezvishoma wedzera HEC kumvura inodziya, ichikurudzira nguva dzose kudzivirira kukoromoka.
Bvumira musanganiswa kuti uise mvura uye uwedzere.
Sanganisa HEC mhinduro ine sipo yemvura base:
Zvishoma nezvishoma wedzera mhinduro yeHEC kune sipo yemvura pachigadziko uchikurudzira zvinyoro.
Iva nechokwadi chekugovera zvakaenzana kuti udzivise clumps uye kusagadzikana.
Monitor viscosity uye gadzirisa sezvinodiwa.
pH kugadzirisa:
Edza pH yemusanganiswa uye gadzirisa kana zvichidikanwa uchishandisa citric acid kana sodium hydroxide.
Kuchengetedza iyo yakakodzera pH siyana kwakakosha pakugadzikana kwekuumbwa.
Edzai uye gadzirisa:
Viscosity bvunzo dzakaitwa pamatanho akasiyana siyana kukwidziridza kuwanda kweHEC.
Gadzirisa resipi zvichibva pamhedzisiro yebvunzo kusvikira kuenderana kunodiwa kwaitwa.
Kugadzikana uye kuchengetedza kufunga:
Anti-corrosion system:
Batanidzai akakodzera kuchengetedza system kudzivirira kusvibiswa kwehutachiona uye kuwedzera hupenyu hwesherufu yesipo yakakora yemvura.
Package:
Sarudza akakodzera ekurongedza zvinhu izvo zvisingaite nesipo yemvura kana kukanganisa HEC kugadzikana.
Mamiriro ekuchengetera:
Chengeta sipo yemvura yakakora munzvimbo inotonhorera, yakaoma kure nechiedza chezuva kuti ichengetedze kugadzikana uye kunaka kwayo kwenguva refu.
Hydroxyethylcellulose yakakosha thickener inopa mhinduro yekuwana inodiwa viscosity mune yemvura sipo maumbirwo.Nekunzwisisa zvimiro zvayo, zvinhu zvinokanganisa kukora, uye nhanho-ne-nhanho yekusanganisa maitiro, vagadziri vanogona kugadzira emhando yepamusoro sipo yemvura ine kuwirirana kukuru uye kuita.Kuedza, kuyedza uye optimization zvinhu zvakakosha zvemaitiro, kuve nechokwadi chekuti chigadzirwa chekupedzisira chinosangana nekushanda uye nekunakisa zvinodiwa.Nekunyatsofunga nezve zvinongedzo uye maitiro ekugadzira, vagadziri vesipo yemvura vanogona kupa vatengi chigadzirwa chemhando yepamusoro uye chinonakidza.
