Ifenitshala yesikhumba yenziwe ngokusebenzisa iintlobo ezininzi zesikhumba ezidalwe ngokusebenzisa iinkqubo ezahlukeneyo. Yiloo nto ebangela inkangeleko eyahlukileyo, imvakalelo kunye nomgangatho wefenitshala yesikhumba, kwaye ekugqibeleni nokuba uyicoca njani.

Isikhumba sivela kwimithombo emininzi eyahlukeneyo. Ezinye zicacile, njengeenkomo, iigusha kunye neehagu, kwaye ezinye azibonakali kangako, njengezinambuzane kunye neenciniba. Nangona kunjalo, yindlela elungiswa ngayo ufele emisela ukuba zeziphi iindidi ezintathu eziphambili eziwela kwi-aniline, i-semi-aniline, kunye nesikhumba esikhuselweyo okanye esinemibala.

Aniline Isikhumba

Isikhumba seAniline sixabiswa kakhulu ngendlela ekhangeleka ngayo. Lolona hlobo lukhangeleka ngokwendalo lwesikhumba kwaye lugcina iimpawu ezizodwa zomphezulu njengemivalo yemingxuma. Isikhumba se-Aniline sidaywe ngokuntywiliselwa kwisikhumba kwindawo yokuhlambela idayi ebonakalayo, kodwa inkangeleko yobuso iyagcinwa ngenxa yokuba ayifakwanga naziphi na iipolymers ezongezelelweyo okanye i-pigments. Kuphela ezona zikhumba zibalaseleyo, malunga neepesenti ezi-5 okanye kunjalo, zisetyenziselwa ufele lweaniline kuba zonke iimpawu zomhlaba zihlala zibonakala. Esi sesona sizathu sisoloko sibizwa ngokuba "yisikhumba seze."

Iingenelo: Isikhumba se-Aniline sikhululekile kwaye sithambile ukubamba. Ekubeni igcina zonke iimpawu ezikhethekileyo kunye neempawu zesikhumba, isiqwenga ngasinye sihluke kuyo nayiphi na enye.

Iingxaki: Ekubeni ingakhuselwanga, isikhumba se-aniline sinokungcoliswa lula. Akukhuthazwa ukuba kusetyenziswe ifenitshala kwiintsapho ezincinci okanye kwiindawo eziphezulu zezithuthi ngenxa yeso sizathu.

Semi-Aniline Isikhumba

Isikhumba se-aniline siqinile kancinci kunesikhumba se-aniline ngenxa yokuba umphezulu waso uphathwe ngedyasi ekhanyayo equlethe i-pigment, eyenza umhlaba- kunye nokumelana namabala. Oko kwenza isiphumo sokufa sahluke kancinane kuba nolona tshintsho luncinci kwinkqubo ludala isiphumo esahlukileyo.

Iingenelo: Nangona igcina ukungafani kwesikhumba se-aniline, i-semi-aniline yesikhumba inombala ongaguqukiyo kwaye iyakwazi ukumelana namabala. Iyakwazi ukumelana neemeko ezinzima kwaye ayonakaliswa ngokulula. Iziqwenga eziphakanyiswe ngesikhumba semi-aniline nazo zinokungabizi kakhulu.

Iingxaki: Iimpawu azibonakali kwaye ngoko ke isiqwenga asinaso isibheno esikhethekileyo esenziwa ngesikhumba se-aniline. Ukuba ungumlandeli wesikhumba se-aniline esijongeka ngokwendalo, ke le asiyoyakho.

Isikhumba esikhuselweyo okanye esinePigmented

Ulusu olukhuselweyo lolona hlobo oluhlala luhlala lwesikhumba, kwaye ngenxa yeso sizathu, sesona sithwathwa esisetyenziswa ngokuqhelekileyo kwifenitshala yokuvelisa kunye nemoto yemoto. Ulusu olukhuselweyo lunomgangatho wepolymer wokugquma oqulathe ibala, nto leyo eyenza ukuba lolona luqilima kwezi ntlobo zintathu.

Ulusu olukhuselweyo lunoguquko kwi-coat surface, kodwa ngokuyongeza njengenxalenye yenkqubo umenzi unolawulo olungakumbi kwiipropati zesikhumba. Ukwaleka kwakhona yongeza ukuxhathisa ngakumbi scuffing okanye fading.

Iingenelo: Isikhumba esikhuselweyo okanye esinemibala kulula ukuyigcina kwaye ime kwiimeko ezahlukeneyo kunye nokusetyenziswa. Kukho amanqanaba ahlukeneyo okhuseleko, kwaye kufuneka ukwazi ukufumana uhlobo oluhambelana neemfuno zakho.

Iingxaki: Olu hlobo lwesikhumba alunayo into ekhethekileyo yesikhumba se-aniline kwaye ibonakala ingaphantsi kwendalo. Kunokuba nzima ukwahlula olunye uhlobo lwengqolowa kolunye ngenxa yokuba umphezulu womhlaba ugqunywe kwaye ugxininiswe.
