1. Nheyo
Kana iyo mvura-based resin yakaputirwa pamusoro peiyo substrate, chikamu chekunyorova mumiriri chiri pazasi pejasi, iyo inosangana nepamusoro kuti inyoroveswe, iyo lipophilic segment inoshambadzirwa panzvimbo yakasimba, uye boka re hydrophilic rinowedzera kunze kumvura.Iko kusangana pakati pemvura ne substrate inova kusangana pakati pemvura neboka re hydrophilic remugadziri wemvura, kugadzira sandwich chimiro neanonyorova seyepakati layer.Ita kuti zvive nyore kuparadzira chikamu chemvura, kuitira kuti uwane chinangwa chekunyorova.Chimwe chikamu chemvura-based wetting agent chiripo pamusoro pemvura, boka rayo re hydrophilic rinosvika kumvura yemvura, uye boka re hydrophobic rinoratidzwa kumhepo kuti rigadzire monomolecular layer, iyo inoderedza kushushikana kwepamusoro kwejasi uye. inokurudzira kunyorova kwejira.substrate, kuitira kuti uwane chinangwa chekunyorova.
2. Chimwe chiitiko mukushandiswa kwemvura-based wetting agents
Mukugadzirwa chaiko, kana uchitarisa kugona kunyorova kweresin, kwete chete saizi yekusimba kwayo kwakamira pamusoro, asiwo saizi yekusimba kwepasi tension inoda kutariswa, nekuti mukuita kwekuputira resin, pasi pekuita kwekushushikana. panguva ino Kudzikira kusimba kwesimba kwepasi, kunowedzera kunyorova.Panguva ino, iyo inokurumidza kunyorovesa mumiriri inoumba monomolecular layer pamusoro peiyo coating, ndiko kuti, nekukurumidza kuumbwa kweiyo oriented molecular layer, iyo inonyanya kuita wetting.Iyo fluorine-ine wetting agent inonyanya kuderedza iyo static surface tension, uye iyo silicone-based wetting agent inogona kuderedza kusimba kwepasi kusimba zvakanyanya.Nokudaro, mukushanda kwekushanda kwekushanda, zvakakosha zvikuru kusarudza yakakodzera wetting agent maererano nemamiriro chaiwo.zvakakosha
3. Basa remvura-based dispersants
Basa remvura-based dispersants nderokushandisa kunyorova uye kuparadzira vamiririri kuderedza nguva uye simba rinodiwa kuti ripedze kupararira, kudzikamisa yakapararira pigment dispersion, kushandura nzvimbo dzepamusoro dze pigment particles, uye kugadzirisa kufamba kwe pigment particles.Kunyanya kuratidzwa muzvikamu zvinotevera:
1. Kuvandudza kupenya uye kuwedzera kuenzana kwemaitiro.Kupenya kunonyanya kuenderana nekupararira kwechiedza pamusoro pekupfeka (kureva kuti, imwe nhanho yekupfava. Chokwadi, zvinodikanwa kuti uone kana iri sandara zvakakwana nechiridzwa chekuyedza, kwete chete nhamba uye chimiro. yezvikamu zvekutanga, asiwo nzira yavo yekusanganiswa), apo chiyero chechidimbu chiri pasi pe 1/2 yechiedza chechiitiko (ichi kukosha hachina chokwadi), chichaonekwa sechiedza chakasvibiswa, uye gloss haizowedzere.Saizvozvo, iyo inovhara simba inotsamira pakuparadzira kupa iyo huru yekuvharisa simba haizowedzere (kunze kwekunge Carbon dema inonyanya kutora mwenje, kanganwa nezve organic pigments).Cherechedza: Chiedza chechiitiko chinoreva huwandu hwechiedza chinooneka uye kuenzana hakuna kunaka;asi teerera kuderedzwa kwenhamba yezvikamu zvekutanga, izvo zvinoderedza maitiro e-viscosity, asi kuwedzera kweiyo nzvimbo chaiyo kunoderedza nhamba yemahara resins.Kana pane bharanzi poindi hazvina kunaka.Asi kazhinji, kuenzana kwehupfu hwehupfu hakuna kunaka sezvinobvira.
2. Dzivirira ruvara runoyangarara kubva pakutumbuka.
3. Kuvandudza tinting simba Cherechedza kuti tinting simba haina yakakwirira sezvinobvira mune otomatiki toning system.
4. Deredza viscosity uye kuwedzera pigment loading.
5. Kuderedza flocculation kwakafanana neizvi, asi iyo yakatsetseka iyo particle, iyo yakakwirira pamusoro pesimba, uye
iyo inoparadzanisa ine yakakwirira adsorption simba inodiwa, asi iyo inopararira ine yakawandisa adsorption simba inogona kukonzera yakashata mhedzisiro pakuita kweiyo bhaisikopo rekuvhara.
6. Chikonzero chekuwedzera kugadzikana kwekuchengetedza kwakafanana nepamusoro apa.Kamwe kugadzikana kweanoparadzira hakuna kukwana, kugadzikana kwekuchengetedza kunowedzera kuipa (zvechokwadi, haisi dambudziko kubva pamufananidzo wako).
7. Wedzera kukura kwemavara, kuwedzera kuzara kwemavara, kuwedzera kujeka (organic pigments) kana kuvanza simba (inorganic pigments).
