Muchidhindo chenguva refu, iyo inki inorasikirwa zvishoma nezvishoma, uye viscosity inowedzera zvisingawanzoitiki, izvo zvinoita kuti ingi jelly-yakafanana, Kushandiswa kunotevera kweinki yakasara kunonyanya kuoma.
Chikonzero chisina kujairika:
1, Kana iyo inonyungudutsa muinki inodhinda yakanyungudika, dova rinogadzirwa nekunze kwakadzika tembiricha rinosanganiswa muinki yekudhinda (kunyanya zviri nyore kuitika muyuniti umo kushandiswa kweingi yekudhinda kudiki kwazvo).
2, Kana iyo inki ine hukama hwepamusoro nemvura ikashandiswa, iyo inki itsva inokora zvisingaite.
Mhinduro:
1,Kurumidza-kuomesa zvinonyungudutsa zvinofanirwa kushandiswa zvakanyanya sezvinobvira, asi dzimwe nguva mvura shoma inozopinda muinki yekudhinda kana tembiricha yakakwira uye ine mwando.Kana kukanganisa kukaitika, inki itsva inofanira kuzadzikiswa kana kutsiviwa nenguva.Iyo inki inosara inoshandiswa kakawanda inofanira kusefa kana kuraswa nguva nenguva nekuda kwekubatanidzwa kwemvura neguruva.
2, Kurukurai kukora kusingaite nemugadziri weinki, uye gadzirisa magadzirirwo einki kana zvichidikanwa.
Kunhuhwirira (solvent residue):Iyo organic solvent muinki yekudhinda ichanyanya kuomeswa muomesa ipapo ipapo, asi yasara trace solvent ichasimbiswa uye yoendeswa kune yekutanga firimu kuti irambe iripo.Kuwanda kwepamusoro-concentration organic solvent residues munyaya yakadhindwa inogadzirisa zvakananga kunhuwa kwechigadzirwa chekupedzisira.Kuti hazvina kujairika zvinogona kutongwa nekunhuhwa mhuno.Ehe, nekufambira mberi kwesainzi uye tekinoroji, kunhuwa kuburikidza nemhino kwakawira kumashure zvakanyanya.Kune zvinhu zvine zvakakwirira zvinodiwa kune zvinonyungudutsa zvinosara, zviridzwa zvehunyanzvi zvinogona kushandiswa kuzviyera.
Chikonzero chisina kujairika:
1,Kudhinda kumhanya kwakanyanya
2, Inherent zvimiro zve resins, additives uye binder mukudhinda inki
3, Kuomeswa kwekuita kwakadzikira kana nzira yekuomesa iri kushomeka
4,Nhepo yemhepo yakavharwa
Mhinduro:
1. Kuderedza zvakakodzera kudhinda nokukurumidza
2. Mamiriro ezvakasara solvent mukudhinda inki inogona kutaurirana nemugadziri weinki kutora matanho.Iko kushandiswa kwekukurumidza-kuomesa solvent kunongoita kuti solvent inyunguke nekukurumidza, uye haina zvakawanda zvinokonzeresa kudzikisa yakasara huwandu hwekunyungudutsa.
3. Shandisai-fast-drying solvent kana pasi-temperature drying (kukurumidza-kuomesa kuchaita kuti pamusoro peinki crusted, izvo zvichakanganisa evaporation yemukati solvent. Kunonoka-kuoma kunoshanda mukuderedza kusara kwehuwandu hwekugadzirisa.)
4. Sezvo iyo yakasara organic solvent inobatanidzawo nemhando yefirimu yepakutanga, chiyero chezvakasara chinogadziriswa chinosiyana nemhando yefirimu yepakutanga.Kana zvakakodzera, tinogona kukurukura dambudziko rezvinonyungudutsa zvakasara nevagadziri vefirimu neinki yepakutanga.
5. Nguva dzose kuchenesa mhepo yemhepo kuti iite kupera zvakanaka
Nguva yekutumira: Kubvumbi-14-2022
