Matambudziko Anowanikwa uye Matanho ekudzivirira eKuparadzira Dhayi

Disperse madhayi anotarisana nezvinetso zvakaita sekudhaya zvisina kuenzana, recrystallization, agglomeration uye coking.Kudzidzivirira sei?Disperse Dyeing Supplier ichakuzivisa iwe nezvazvo.

1. Kudhaya Kusina Kuenzana
Kufanana kwekutorwa kwedhayi kune hukama nereshiyo pakati pedhayi doro rekuyerera mwero uye kunyura.Muchikamu chekutora ruvara, gwara rekuyerera kwemvura rinoshandurwa ese masere masekete.Kuderedza chiyero chekugezera kubva pa1: 12 kusvika ku1: 6 kunogona kuchinja kufanana kwechikwata chekufamba, kunyange zvazvo dhigirii yekusaenzana pakutanga kwekudhaya iri pachena.Pakusanganisa uye kudhaya, hazvina kukwana kusarudza madhayi ane akafanana diffusion zvimiro kuti ave nechokwadi chekudhaya.

Panguva ino, chiyero chekusanganiswa chinoita basa rinokosha.Kana huwandu hwedhayi hutatu hunoshandiswa mukufananidza ruvara hwakafanana, zvakaringana kushandisa madhayi ane madhizaini akafanana.Zvisinei, kana chikamu chemavara maviri chiri chikuru, diffusible yedhayi yechitatu inofanira kunge yakaderera, kana zvisina kudaro ichapedzwa nokukurumidza kupfuura mamwe madhayi maviri, ayo achaita nyore nyore kudhaya kusina kuenzana.

2. Recrystallization
Disperse Kudhaya kunowanzo dzokorora zvimedu zvakakura kupfuura 1nm nekuda kwekudziya kwakadzokororwa uye kutonhora.Kuwedzera mamwe ma dispersants anogona kuderedza recrystallization.Munguva yekudhayiwa, kana yekugezera yekudhaya yakatonhodzwa kubva pa130 ° C kusvika 90 ° C, mamwe madhayi anowanzo kuve nyore kudzoreredza, zvichikonzera kusasimba kwekutsvaira kwechigadzirwa chakadhayiwa, uye kunyange kuvhara sefa mukupisa kwakanyanya uye kudzvanywa kwemuchina wekudhaya. .

Kudzivirira Matanho
Chengetedza 100 ℃ kwenguva yakareba, dhayi iri nyore kuita agglomerate, gadzirisa kumhanya kwekupisa kubva ku100 ℃ kusvika ku130 ℃;

Kana dhayi iri mubhati rekugezera dhayi recrystallizes mushure mekusvika pachiyero chekudhaya, yakawanda dispersant inofanira kuwedzerwa;

Mamwe madhayi dzvuku anoparadzira anowanzoita recrystallization pakupera kwekudhaya, kunyangwe kana fungidziro yavo yakadzikira pane iyo saturation level, kunyanya kana vachidhaya mavara akasviba.Kunyanya kana uchidhaya nemvura yakaoma, zviri nyore kuita chelate nesimbi ions.Iyo chelate inoguma haina kunyungudika kwakashata pasi pemamiriro ekudhaya uye inosiya mavara ebhuruu kana mitsetse yemavara pamucheka.

Zvinhu zvinokonzera recrystallization

Zvishandiso, mafuta anoputika, masara ealkaline, nezvimwewo akawedzerwa panguva yekutenderera.Aya matambudziko anogona kudzivirirwa nekunatsa usati wadhaya kana kuwedzera chelating agents mudhayi yekugezera.Kana chivara chaitika, chinogona kubviswa nekuchenesa alkaline kuderedza kana kurapwa kweasidhi.

3. Agglomeration uye Focus

Zvinhu zvinoparira
Iyo inoderedza kunyungudika kweiyo dispersant, inoderedza kudzoreredzwa kwemagetsi, uye inowedzera kudhumhana kwezvikamu zvedhayi uye inovandudza kinetic simba ravo.Kazhinji, kukwirisa kwekudhaya uye tembiricha, uye nekurebesa nguva yekudhaya, kunowedzera mukana weagglomeration uye coke.Kudhaya kwekubatsira senge vatakuri uye maajenti ekuyera anogona kutsiva nyore dispersant yakasanganiswa mudhayi, nekudaro ichideredza kupararira kugadzikana.

Matanho ekuvandudza kugadzikana panguva yekudhaya
Kuparadzira dhayi pa40 ° C uye shandisa kupararira kwakanyanyisa;

Iyo yakanakisa tembiricha kutonga kana dhayi doro rinopisa;

Kushandisa dispersant ine inodzivirira colloidal effect;

Usashandise additives ane cloud point pane yakakwirira tembiricha;

Geza dhayi neshinda zvese zvinosanganisira emulsifiers usati wadhaya;

Munguva yekushisa kwekushisa kwepamusoro, hapana mutakuri uye kwete-ionic leveling agent inofanira kuwedzerwa madhayi akawanda asati aiswa dhayi pamucheka;

Hapana munyu, chete acetic acid kugadzirisa kukosha kwePH;

Shinda kana machira akadhayiwa chidimbu anofanirwa kuve akaumbwa zvakanaka, uye bvunzo dzemurabhoritari dzinofanirwa kuitwa kuti ive nechokwadi chekupararira kwedhayi.
