Nhanganyaya: HEC Inova Chinhu Chinokosha Chinobatsira Mukudhinda Kwemachira Kwemazuva Ano

Indasitiri yekudhinda machira iri kuramba ichichinja ichienda pakunyatsorongeka, kushanda zvakanaka kwemavara, uye maitiro ekugadzira ane mutoro kune zvakatipoteredza. Sezvo mabhurandi emafashoni nevagadziri vemachira vachida mapatani akajeka, kugadzikana kwemavara kuri nani, uye maitiro ekudhinda anoshanda zvakanaka, basa rekuwedzera mashandiro mukugadzira mapesiti ekudhinda rave kukosha zvakanyanya.

Pakati pezvinhu zvakasiyana-siyana zvekukora zvinoshandiswa mukudhinda machira,Hydroxyethyl Cellulose (HEC)yakakwezva kutariswa kukuru nekuda kwekudzora kwayo rheological kwakanaka, kugona kwayo kuchengetedza mvura, kuenderana kwayo nedhayi nepigments, uye hunhu hwayo husingakuvadzi nharaunda.

HEC imhando ye cellulose ether isingashandisi ionic inobva mu cellulose yechisikigo kuburikidza nekuchinja kwemakemikari. Nekuda kwechimiro chayo chakasiyana chemamorekuru, HEC inogona kugadzirisa zvinobudirira printing paste viscosity, kugadzirisa kugadzikana kwechiso, kudzivirira kubuda kwemavara, uye kuwedzera kujeka kwemapatani akadhindwa.

Mumichina yekudhinda machira, mhando yepurinti inopesvedzera zvakananga:

• Kupinza kwepatani
• Kupinda kwedhayi
• Kupenya kwemavara
• Kuenderana kwekudhinda
• Chitarisiko chejira
• Kubudirira kwekugadzira

Chinodhindwa chakagadzirwa zvakanaka neHEC chinopa kuyerera kwakaringana: chinoramba chakasimba panguva yekuchengetwa, chinopfuudzwa zvakanaka kuburikidza nemasikirini ekudhinda, uye chinochengetedza kusimba kwakakwana mushure mekuiswa pamachira.

1. Chii chinonzi Hydroxyethyl Cellulose (HEC)?

Hydroxyethyl Cellulose (HEC)i-ether inonyungudika mumvura, isinganyungudike, inogadzirwa nekuita cellulose ne ethylene oxide pasi pemamiriro e alkaline akarongwa.

Kuunzwa kwemapoka ehydroxyethyl kunovandudza kunyungudika kweselulosi uye kunopa hunhu hwakanaka hwekukora.

Hunhu Hukuru hweHEC

HEC inoshandiswa zvakanyanya nekuti inopa kusimba kwakasimba pasina kupindirana zvakanyanya nemunyu, madhayi, kana zvimwe zvinhu zvinowanzo kuwanikwa mumafomu ekudhinda machira.

2. Nei Kudzora Kusviba Kwakakosha Mukudhinda Kwemachira

Kupenya kwepaste yekudhinda ndechimwe chezvinhu zvinonyanya kukanganisa kunaka kwekudhinda kwemachira.

Kana viscosity yakaderera zvakanyanya:

Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa)

Mubvunzo 1: Ndeipi basa guru reHEC mukudhinda kwemachira?

HEC inonyanya kushanda semuchina wekuomesa uye wekugadzirisa rheology. Inovandudza kunaka kwepaste paste, inodzivirira kupararira kwemavara, uye inowedzera kujeka kwemapatani.

Mubvunzo wechipiri: Sei HEC iri nani pane mamwe ma thickeners echinyakare?

HEC inopa kusimba kwakasimba, maitiro akanaka ekuchekerera ganda, inoenderana zvakanaka, uye kugadzikana kuri nani kwekuchengetedza zvichienzaniswa nezvimwe zvinogocha zvechinyakare.

Mubvunzo wechitatu: Ko HEC inogona kushandiswa pakudhinda pigment here?

Ehe. HEC inoenderana nemasisitimu ekudhinda pigment uye inobatsira kudzikamisa kupararira kwepigment uye kuvandudza kuenderana kwekudhinda.

Mubvunzo wechina: Ko HEC inokanganisa kupenya kweruvara rwejira here?

Ehe. Nekuvandudza kugadzikana kwepaste uye kudzora kufamba kwedhayi, HEC inogona kubatsira mukuita kuti ruvara ruve rwakafanana uye rujeke zviri nani.

Mubvunzo wechishanu: HEC yakawanda sei inoshandiswa mukudhinda machira?

Chiyero chinoenderana nezvinodiwa pakudhinda, rudzi rwedhayi, uye mamiriro ejira. Kazhinji, bvunzo dzekugadzirisa dzinodiwa kuti uwane viscosity inodiwa.

Mubvunzo wechitanhatu: HEC ine hushamwari here kune nharaunda?

HEC yakagadzirwa ne cellulose uye ine zvakanakira pakuchengetedza nguva kana tichienzanisa nezvimwe zvinhu zvinosimbisa polymer zvakagadzirwa.

Mubvunzo 7: Ndezvipi zvinhu zvinofanirwa kutariswa pakusarudza HEC yekudhindisa machira?

Zvinhu zvakakosha zvinosanganisira giredhi rekupenya, huremu hwemamorekuru, dhigirii rekutsiva, nzira yekudhinda, uye kuenderana nemadhayi.

Hydroxyethyl Cellulose (HEC) yave chinhu chakakosha chinobatsira pakudhinda kwemachira kwemazuva ano nekuda kwekugona kwayo kudzora kunaka kwekudhinda uye kunatsiridza kujeka kwemapatani.

Nekupa maitiro akagadzikana ekurapa rheological, kuderedza kufamba kwemavara, kuvandudza mashandiro ekudhinda skrini, uye kutsigira zvinangwa zvekugadzira zvinogara kwenguva refu, HEC inobatsira vagadziri vemachira kuwana machira akadhindwa emhando yepamusoro.

Sezvo kudhinda machira kuchienderera mberi nekugadzira nemazvo uye kugadzira zvine chekuita nezvakatipoteredza, HEC icharamba iri mhinduro inokosha ye cellulose ether yekuvandudza kushanda zvakanaka kwekudhinda, mhando yechigadzirwa, uye kugadzikana kwemaitiro.
