Hydroxyethyl cellulose (HEC)ipolymer inonyungudika isinganyungudike mumvura inowanikwa nekushandiswa kwe cellulose yechisikigo nemakemikari. Nekuda kwehunhu hwayo hwakanaka hwekukora, emulsifying, suspending, stabilizing, uye compatibility, HEC inoshandiswa zvakanyanya muindasitiri yemakemikari yezuva nezuva, kunyanya muzvigadzirwa zvekuchenesa mvura zvakaita sezvinwiwa zvekusuka ndiro, sipo dzemaoko, uye shampoos.
1. Basa reHEC muMidziyo yekugeza ndiro
Mukugadzira mvura yekugeza ndiro, mabasa makuru eHEC anosanganisira zvinotevera:
Kukora uye Kudzora: HEC inowedzera kunaka kwechishandiso chemvura yekugeza ndiro, zvichiita kuti chigadzirwa chitaridzike zvakanaka, chigone kuyerera zvakanaka, uye chive neruzivo rwemushandisi.
Kugadzika Kwesimbi: Muzvinwiwa zvinosuka ndiro zvine zvinhu zvinowedzera (zvakadai sekubvisa zvidimbu uye hupfu hwemaparera), HEC inogona kudzivirira kudonha kwezvidimbu uye kuchengetedza kufanana kwekugadzirwa.
Kugadzika Kwefuro: HEC inogona kushanda pamwe chete nemasurfactants kuti ivandudze kunaka uye kugara kwenguva refu kwefuro.
Kugadziriswa Kwekuenderana: Sepolymer isiri yeionic, HEC inoenderana zvakanyanya neanionic, cationic, uye nonionic surfactants, zvichidzivirira kupatsanurwa kwekugadzirwa.
2. HEC Kugadzikana Mechanism
2.1. Kugadzikana kwekupisa
HEC inoratidza kugadzikana kwakanyanya kwekupisa kana tichienzanisa nemapolymer mazhinji echisikigo. Mumasystem emakemikari ezuva nezuva pa25–50°C, HEC inochengetedza chimiro chemorekuru chakasimba uye haikurumidzi kuora.
Kunyangwe mukugadzirwa kwemvura inopisa zvakanyanya (senge panguva yekunyunguduka nekudziya) kana munzvimbo dzekuchengetera kwenguva refu, masisitimu akakora eHEC anochengetedza kunaka kwakanaka pasina kutetepa zvakanyanya. Hunhu uhwu hwakakosha zvikuru pakutengeswa kwakagadzikana kwesipo panguva yekufambisa inopisa zvakanyanya kana mumisika yekumaodzanyemba.
2.2. Kugadzikana kweIonic
Zvinwiwa zvekusuka ndiro zvinowanzova nemunyu wakasiyana-siyana usingashandi (wakadai sesodium chloride nesodium sulfate) uye zvikamu zve electrolyte. Maion aya anowanzo deredza simba rezvishandiso zvinogozha. Zvisinei, sepolymer isiri yeionic, kushanda kweHEC thickening hakukanganisike nekuchinja kwehuwandu hwe electrolyte.
Munzvimbo dzine munyu wakawanda, HEC ichiri kuchengetedza kusviba kwakasimba uye kujeka, ichidzivirira kunaya kwemunyu uye kupatsanurwa kwemusanganiswa wezvinonhuhwirira panguva yekuchengetwa.
2.3. Kugadzikana kwepH
pH yemvura yekugeza ndiro inowanzova pakati pe6.5 ne8.5. HEC inoratidza kugadzikana kwakanaka kwemakemikari mukati merudzi urwu, pasina kuora kana kusashanda. Kunyangwe paine zvinhu zvine alkaline kana acidic zvishoma muchimiro, maHEC molecular chains anoramba aine hydration yakasimba, achichengetedza homogeneity yesystem.
Uyezve, hunhu hweHEC husina ionic hunodzivirira kukanganiswa kwechaji kunokonzerwa nekuchinja kwepH, zvichiita kuti mvura inosuka ndiro irambe yakachena kwenguva yakareba.
2.4. Kugadzikana Kunoenderana
HEC inoenderana zvakanaka nema surfactants akasiyana-siyana (akadai seAES, LAS, APG, nezvimwewo) pasina kukonzera flocculation kana stratification. Maketani ayo emamorekuru anogona kugadzira kusashanda zvakanaka nema surfactants mumushonga, nokudaro zvichivandudza viscoelasticity uye kugadzikana kwefuro remushonga.
Mumasystem akaomarara ane kunhuhwirira kwakagadzirwa, pigments, uye preservatives, HEC inochengetedza kupararira kwakanaka, ichidzivirira kupatsanurwa kwechikamu kana kunaya kwemvura panguva yekuchengetwa kwenguva refu.
3. Zvinhu Zvikuru Zvinokanganisa Kugadzikana kweHEC
3.1. Dhigirii rekutsiva (DS) uye Giredhi rekusviba:
MaHEC ane mwero wekutsiva ane mwero wekuchinjisa zvinhu anonyungudika zviri nani uye anotsungirira munyu zviri nani, zvichiita kuti akwanise kushandiswa mukugadzira sipo yakajeka; zvigadzirwa zvine mwero wekutsiva zvine mwero wekuchinjisa zvinhu zvine mwero wekukora wakasimba asi kugadzikana kwakaderera zvishoma. Kazhinji, maHEC ane mwero wekukora wepakati kusvika wepamusoro (25000–60000 mPa·s) anosarudzwa kuti aenzanise kukora uye kupenya zviri nani.
3.2. Maitiro Ekugadzirisa:
HEC inofanira kutanga yapararira zvakaenzana mumvura inotonhora, yozodziiswa zvishoma nezvishoma kuti inyungudike zvachose, kudzivirira kuungana. Kusanyungudika kwakakwana kunogona kukonzera tumarara kana turbidity musystem, zvichikanganisa kugadzikana kwekugadzirwa kwayo.
3.3. Kuwanda kweElectrolyte mukugadzirwa:
Kunyange zvazvo HEC ichikwanisa kushivirira munyu zvakanaka, kuderera kudiki kwe viscosity kunogona kuitika kana huwandu hwe electrolyte mu system hwakanyanya (>6% NaCl). Saka, mumafomu ane munyu wakawanda, huwandu hweHEC hunowedzerwa hunofanira kuwedzerwa zvakakodzera, kana kuti mhando yeHEC yakagadziriswa inofanira kusarudzwa.
3.4. Rudzi rweSurfactant:
Kuenderana kweHEC nemasisitimu akasiyana esurfactant kunosiyana zvishoma. Semuenzaniso, HEC inoratidza kugadzikana kwakanyanya kwefuro mumasisitimu eLAS neAES; nepo mumadhishi ekuwachisa ndiro asina njodzi kune zvakatipoteredza ane APG, mhedzisiro yeHEC yekusimba uye yekumisa inoonekwa zvakanyanya.
4. Mabhenefiti eHEC muMidziyo Yekushambidza Dishwashing
Kujeka Kwakanyanya: Mvura yakanyungudutswa yakajeka uye inoonekera, isingakanganisi chitarisiko chemvura inosuka ndiro.
Kuora Kwezvinhu Zvakanaka: Yakabva mu cellulose yechisikigo, inoenderana nemaitiro ezvigadzirwa zvemakemikari zvezuva nezuva zvisingakuvadzi nharaunda.
Kusatsamwisa: Hazvikonzeri kurwara kweganda uye zvakakodzera kushandiswa musanganiswa wemvura inosuka ndiro zvishoma.
Kuenderana Kwakakura: Inoshanda kumhando dzakasiyana dzemasisitimu emvura yekugeza ndiro, senge mvura yekugeza ndiro isina kusimba, mafomura akaomeswa, uye mafomura ane furo rakawanda kana rakaderera.
HECHaingori chete chinhu chinosimbisa ganda zvakanaka mukugadzira mvura yekugeza ndiro asiwo chinhu chakakosha chinosimbisa hurongwa. Kugadzikana kwayo kwakanyanya kwekupisa, kugadzikana kweionic, kugadzikana kwepH, uye kuenderana kunoita kuti mvura yekugeza ndiro irambe ichitaridzika zvakanaka uye ichishanda zvakanaka panguva yekuchengetwa, kutakurwa, uye kushandiswa. Nekusarudza zvine musoro mhando dzeHEC uye maitiro ekuwedzera, mhando yese uye kukwikwidzana kwemusika kwemvura yekugeza ndiro kunogona kuvandudzwa zvakanyanya. Mune ramangwana, nekuvandudzwa kwekuchengetedzwa kwezvakatipoteredza zvakasvibira uye makemikari anogara kwenguva refu, HEC icharatidza mikana yakakura yekushandisa muzvigadzirwa zve detergent zvepamusoro.
