Isingeniso

I-Pigment red 179, eyaziwa nangokuthi i-azo red 179, i-organic pigment. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha lwe-Pigment Red 179:

 

Ikhwalithi:

- Umbala: I-Azo ebomvu engu-179 ibomvu ngokumnyama.

- Isakhiwo samakhemikhali: inkimbinkimbi eyakhiwe amadayi e-azo nama-axiliary.

- Ukuzinza: Izinzile ngokuqhathaniswa phezu kwebanga elithile lokushisa ne-pH.

- Ukugcwaliswa kwesikhala: I-Pigment Red 179 inombala ophezulu wokugcwala.

 

Sebenzisa:

- Ama-Pigments: I-Azo ebomvu engu-179 isetshenziswa kakhulu ku-pigments, ikakhulukazi kumapulasitiki, amapende kanye nama-coatings, ukuhlinzeka ngombala obomvu noma owolintshi obomvu ohlala njalo.

- Oyinki bokuphrinta: Iphinde isetshenziswe njenge-pigment kumayinki wokuphrinta, ikakhulukazi ekuphrinteni okusekelwe emanzini kanye ne-UV.

 

Indlela:

Indlela yokulungiselela ngokuvamile ihlanganisa lezi zinyathelo ezilandelayo:

Amadayi e-Azo okwenziwa: Odayi be-azo bokwenziwa bahlanganiswa ngezinto ezingavuthiwe ezifanele ngokusabela kwamakhemikhali.

Ukwengezwa kwe-adjuvant: Udayi wokwenziwa uxutshwa ne-adjuvant ukuze uwuguqule ube nemibala.

Ukucutshungulwa okuqhubekayo: I-Pigment Red 179 yenziwa yaba usayizi wezinhlayiyana oyifunayo kanye nokuhlakazwa ngezinyathelo ezinjengokugaya, ukuhlakazwa kanye nokuhlunga.

 

Ulwazi Lokuphepha:

- I-Pigment Red 179 ngokuvamile ibhekwa njengephephile uma kuqhathaniswa, kodwa okulandelayo kufanele kuqashelwe:

- Ukucasuka kwesikhumba kungenzeka lapho uthintana, ngakho-ke amagilavu ​​kufanele agqoke lapho usebenza. Uma uthinta isikhumba, geza ngokushesha ngensipho namanzi.

- Gwema ukuhogela uthuli, sebenzisa endaweni enomoya omuhle, futhi ufake imaskhi.

- Gwema ukudla nokugwinya, futhi ufune usizo lwezokwelapha ngokushesha uma udliwe ungaqondile.

- Uma kukhona ukukhathazeka noma ukungakhululeki, yeka ukusebenzisa futhi uthintane nodokotela.
