Iyiphi indima i-hydroxyyethyl methyllulose play ekushicilelweni kwendwangu nodayi?

I-Hydroxyyethyl methyllulose (hemc) iyingxenye evamile ye-cellulose ether compound esetshenziswa kabanzi kuzinqubo zokuphrinta nezinkinga zokudaya, ikakhulukazi edlala izindima eziningi ezinjengesisekelo sokubona, ukuzinza, kanye nokwakheka kwefilimu.

1. Njengomuntu omkhulu ukulawula ukubonwa kwe-slurry
Enqubweni yokuphrinta nokudaya, ukubonakala kwe-slurry yokuphrinta kungenye yezinto ezibalulekile ezanquma ikhwalithi yokuphrinta. I-Hemc ine-solubility yamanzi enhle kanye nemithetho yokulawulwa kwe-viscosity, futhi isixazululo saso singagcina izakhiwo ezizinzile ze-rherological ngaphezulu kobubanzi bezinga lokushisa. Usebenzisa i-hemc ukulungisa i-slirry viscosity ingathuthukisa ngempumelelo ukucaciswa nokufana kwephethini yokuphrinta nokudaya, ukuvimbela ukungena ngokweqile noma ukubekezela kokukhanya kwelanga, futhi kuqinisekiswe nemingcele yephethini ecacile.

2. Ukwenza ngcono ukuqina kwe-slurry
I-Hemc inokumiswa okuhle nokukhulisa amakhono, okungavimba imvula kanye nokuhlukaniswa kwezinhlayiya noma izinhlayiya zamadayi ekuphrintiwe nokudaya okusatshalaliswa ngokulinganayo. Lokhu kuzinza kubalulekile ekuqhubekeni nokuguquguquka kwenqubo yokuphrinta, futhi kusiza ukunciphisa ukwehla komehluko wombala nokungalingani.

3. Nikeza ukusebenza okuhle kakhulu nokusebenza kokwakha
Enqubweni yokuphrinta, i-hemc ingakhulisa izakhiwo ze-rhelogical ze-slurry, okwenza kube nokusebenza okuhle nokusebenza. Ngesikhathi sokuphrinta nokudaya, ama-slurry angasakazeka ngobuqili ebusweni bendwangu ukuze agweme amaphutha afana namamaki okuhudula nama-bubble, ngaleyo ndlela athuthukise ikhwalithi yokuphrinta.

4. Ukwakha amafilimu nokwemelana namanzi
Isixazululo se-hemc sizokwakha ifilimu elincanyana ngemuva kokomiswa. Le mpahla eyakha ifilimu ingadlala indima evikela inqubo yokuphrinta nokudaya. Ngakolunye uhlangothi, kungalungisa udayi noma umbala wokuphrinta ku-slurry yokuphrinta ukuvikela ukulahleka kwawo; Ngakolunye uhlangothi, futhi kungathuthukisa ukunamathela kokushayisana kokuphrinta, ukuze udayi afakwe ngokuqinile endaweni ye-fiber ngesikhathi sokulungiswa kombala olandelayo kanye nenqubo yokugeza.

5. Kulula ukugeza kanye nezimpawu zokuvikela imvelo
I-Hemc igcotshwa kalula emanzini, futhi izinsalela zingasuswa ngokugeza kwamanzi okulula ngesikhathi senqubo yokwelashwa kwangemva kokuthinta kabi izindwangu. Ngasikhathi sinye, kuyindawo engeyona eye-ionic, futhi akukho ukungcoliswa kwe-ion okweqile okuzokwethulwa ngesikhathi sokusetshenziswa, okuhlangabezana nezidingo zomkhakha wanamuhla wokuphrinta wokuvikela ukuvikelwa kwemvelo kanye nentuthuko esimeme.

6. Ukuguquguquka kwemicu ehlukene
IHemc ilungele izinhlobo ezahlukahlukene zezinto zokwenziwa zefayibha, ezinjengokotini, i-polyester, isilika, njll. Ekushicilelweni kwendwangu nokotini, i-hemc ingathuthukisa kakhulu ukuvumela kanye nokufana kwamadayi; Enqubweni yokuphrinta yemicu yokwenziwa njenge-polyester kanye nosilika, i-hemc nayo inomthelela obalulekile wokulawula ku-slurry, esiza ukuthuthukisa ukusebenza kahle nokudaya nokudaya ukusebenza kanye nekhwalithi.

7. Thuthukisa ukumelana kwe-freeze-thaw kanye nokumelana nokushisa
Ezindaweni ezibandayo noma eziphakeme zokushisa, ukuphrinta nokudaya ama-slurlies angathola ukuguqulwa kwe-viscosity noma izinkinga zokuthambekela. I-HEMC inokumelana kahle nokumelana nokushisa okushisa, okungaqinisekisa ukuthi amaSlurry ahlala azinzile ngaphansi kwezimo ezahlukahlukene zezemvelo futhi ayithinti umphumela wokuphrinta ngenxa yokushintshashintsha kwezinga lokushisa.

8. Umphumela we-Synergistic nezinye izengezo
I-Hemc ingasetshenziswa ngokuhambisana nezinye izifebe, ama-ejenti axhumanisa ama-cellulose, ama-ejenti kanye nezinye izengezo ukuze zithuthukise ukusebenza okuphelele kokuphrinta nokudaya ukuncibilikisa. Isibonelo, lapho kusetshenziswa ngokuhlanganiswa ne-hydroxypropylly methylcellulose (HPMC), izakhiwo zesimbobo sezikhumba zingathuthukiswa; Kuhlanganiswe ne-ejenti exhumanisayo, kungathuthukisa ukumelana nokuhlanza nokuqina kwephethini yokuphrinta nokudaya.

IHydroxYethyl Methylcellulose idlala izindima eziningi ekuphrintweni kwendwangu nodayi. Ukuqina kwayo okuhle kakhulu, ukwakha amafilimu, ukuqina kanye nokuvikelwa kwemvelo akunakuthuthukisa ikhwalithi yemikhiqizo yokuphrinta nokudaya, kepha futhi kuhlangabezana nezidingo zemboni yanamuhla yokuvikelwa kwemvelo okuluhlaza. Iqhutshwa ngobuchwepheshe obusha kanye nokwenza kahle kwesicelo, i-hemc izokwenza amandla amakhulu emkhakheni wokuphrinta wendwangu nodaya futhi anikeze ukwesekwa kwentuthuko yemboni.
