Iindaba

Kule mihla, abantu banikela ingqalelo kwikharbhon esezantsi kunye nokukhusela kwendalo, ke xa kuhlotywa, uninzi lwabantu luya kukhetha iingubo ezimbi zendalo. Namhlanje sithetha ngokusingqongileyo. Ingubo yangaphantsi yamanzi ihlulwe ikakhulu ibe ziindlela ezimbini zokunxiba: iingubo ezinyibilikayo zamanzi (iingubo ezisekwe ngamanzi) kunye neengubo ezisekwe kwi-Solvent. Ke yintoni umahluko phakathi kwezi zitya zimbini zokunxiba amanzi?

Umahluko phakathi kwengubo esekwe emanzini kunye neengubo ezisekwe kwi-Solvent inokuchazwa kwezi mbono zilandelayo:

A. Umahluko kwiinkqubo zokudibana

1. I-resin yahlukile. I-resin yepeyinti esekwe emanzini kukunyibilika kwamanzi kwaye inokusasazeka (inyibilikisiwe) emanzini;

I-2. I-dieuent (isolvent) yahlukile. Iipeyinti ezisekwe emanzini zinokuchithwa ngamanzi edini (amanzi) nakweyiphi na indawo, ngelixa iipeyinti ezisekwe kwi-Solvent zinokuchithwa kuphela zizinyibilikisi zendalo (ioyile ye-odorsed, njl. Njl.).

B. Iimfuno ezahlukeneyo zokwakha

1. Kwindawo yokwakha, indawo yokwakhiwa kwamanzi yi-0 ° C, i-caatS enamanzi ayinakusetyenziswa ngaphantsi kwe-5 ° C, ngelixa iingubo ezisekwe kwiSolvent zinokusetyenziswa ngaphezulu -5 ° C, kodwa isantya sowoyikayo siyacothisa phantsi kwaye isithuba esiphakathi kweendlela ziya kuqiniseka;

2. Kwi-viscofity yokwakha, ukuncitshiswa kwe-viscofity yamanzi akulunganga, kwaye ipeyinti esekwe emanzini iya kuba yingxaki xa ithe yancitshiswa kwaye incitshisiwe kwi-viscofity (ukuncitshiswa kwe-viscosity kuya kunciphisa kakhulu umxholo oqinileyo we-fluid, ukuchaphazela amandla okuphupha, kwaye kwandise inani lokuqhubeka kokwakhiwa), uhlengahlengiso olusekwe ngokusekelwe kwi-Sonvent lube lula, kwaye umda wokubonakala uza kuchaphazela nokukhetha indlela yokwakha;

3. Ukomisa kwaye kucandwe, ipeyinti esekwe emanzini icocekile, umswakama uphakamileyo kwaye iqondo lokushisa liphantsi, kodwa ukuba amaqondo obushushu avuthiwe, Ipeyinti kufuneka ifuduselwe kwigrafient, kwaye iya kungena kwindawo yobushushu obuphezulu. Emva komphezulu wepeyinti esekwe emanzini okupheliswa komgangatho wangaphakathi wamanzi kunokubangela i-pinholes okanye i-bubbling enkulu, kuba kuphela amanzi asetyenziswa njengepeyinti esekwe emanzini, kwaye akukho prodialculculculty esekwe emanzini, kwaye akukho prodialculculculation. Ngeengubo ezisekwe kwisiseko, i-dieuent yenziwa zizicolo zezinto eziphilayo ngamanqaku awolisayo abilayo, kwaye kukho iigragils ezininzi zokuzivocavoca. I-phenomena efanayo ayizukwenzeka emva kokukhanya (ixesha elomileyo emva kokuba ulwakhiwo lugqityiwe kwithuba elomileyo ngaphambi kokungena kwi-oveni).

C. Umahluko ekuhlekiseni ukuhonjiswa emva kokuqulunqwa kwefilimu

C-1. Inkcazo eyahlukileyo yeglosass

I-1. Ukunxiba okusekwe kwi-Solvent kungawulawula ukulunga kwee-pigments kunye neefilitha ngokwesigaba, kwaye akukho lula ukuthambeka ngexesha lokugcina. Ngokongeza i-resins ukulawula i-PVC yokuthintela i-PVC (i-pigment-ye-oxtiment), i-arsertives (njengabamelisi) ukufezekisa iinguqu kwi-Glossical Bible, iMatte, iMatte, i-Semi-Matte, glass. I-Gloss yepeyinti yemoto inokuba phezulu njenge-90% okanye ngaphezulu;

2. Ukubonakaliswa kwe-gloss yepeyinti esekwe emanzini akubanzi kangako kwiipeyinti ezisekwe kwioyile, kunye nentetho ephezulu kakhulu ihlwempu. Kungenxa yokuba amanzi kwipeyinti esekwe emanzini asetyenziswa njengelindle. Iimpawu zokuzibongoza kwamanzi zenza kube nzima kwiipeyinti ezisekwe emanzini

Vakalisa ngaphezulu kwe-85% ephezulu. .

C-2. Inkcazo yemibala eyahlukeneyo

I-1. Iingubo ezisele zisekwe kwi-Solvent zinoluhlu olubanzi lwee-pigments kunye neefilitha, nokuba i-inrganic okanye i-organic, ke imibala eyahlukeneyo ilungelelaniswe, kwaye intetho yombala igqibelele;

2. Uluhlu lokukhetha ii-pigments kunye neefilimu zeepeyinti ezisekwe emanzini zincinci, kwaye uninzi lwee-pigments azinakusetyenziswa. Ngenxa yethoni yombala engaphelelanga, kunzima ukuhlengahlengisa imibala etyebileyo efana nepeyinti esekwe kwiSolvent.

D. Ukugcina kunye nokuhamba

Iipeyinti ezisekwe emanzini aziqukethe izinyibilikisi ezinokutsha, kwaye zikhuselekile ukugcina kunye nokuhambisa. Kwimeko yongcoliseko, banokuhlanjwa kwaye bathenjelwa ngamanzi amaninzi. Nangona kunjalo, iipeyinti ezisekwe emanzini zinemifuno yobushushu yokugcina nokuhamba. Ubisi kunye nezinye ii-bill.

E. Denal Devercendence

Iingubo ezisekwe kwi-SOLLPE kakhulu ziimveliso zezinto eziphilayo, kwaye iimveliso zezinto eziphilayo ziya kuba nothotho lweengxaki ezifana nekatiko kunye nekharbhonization phantsi kweemeko zobushushu obuphezulu. Okwangoku, ukuchasana kobushushu obuphezulu beemveliso ze-organic akudluli kwi-400 ° C.

Iingubo ezikhulu eziphezulu zeqondo lokunganyangeki zisebenzisa i-Inorganic ekhethekileyo kwi-Inorganic ekhethekileyo kwi-cares-esekwe emanzini inokumelana namaqondo obushushu amawaka. Umzekelo, ii-ZS ezinamanzi anokuhlala phantsi kwamaqondo obushushu angathathi ntweni zingangeni nje ipropathi ye-anti-yosulelo kunye ne-anti-oxidation yeengubo eziqhelekileyo, kodwa kunye nexesha elide lobushushu, ukuya kuthi ga kwi-3000 ℃ iqondo lobushushu eliphezulu, eliyiyo akunakwenzeka ukuba kwenziwe ikhreyithi.

G. Umahluko kwizokhuseleko kunye nokukhusela okusingqongileyo

Iingubo ezisele zisekwe kwi-Solvent zinengxaki yokhuseleko yomlilo kunye nokuqhuma ngexesha lokuvelisa, ukuhambisa, ukugcinwa, kunye nokusetyenziswa. Ingakumbi kwiindawo ezivaliweyo, zinokwenzeka ukuba zibangele ukufudumeza kunye nokuqhuma. Kwangelo xesha, izinyibilikisi zezinto eziphilayo ziya kubangela umonakalo othile emzimbeni womntu. Esona tyala lidumileyo yimeko ye-toluene ebangela umhlaza, kwaye u-Euluene akasavunyelwa ukuba asetyenziswe. I-VOC yewotshi esekwe kwiSolvent iphezulu, kwaye iimveliso eziqhelekileyo ziphezulu kakhulu nangaphezulu kwe-400. Amashishini aphantsi koxinzelelo olukhulu lokukhusela okusingqongileyo nokhuseleko xa besenza ikhreyithi esekwe kwi-Solvent.

I-cares ezikwekwe emanzini inobuhlobo kwaye ikhuselekile kwimveliso, ukuthutha, ukugcinwa, kunye nokusetyenziswa (ngaphandle kwemveliso emanzini e-pseudo).

ISIQINISEKISO:

Iingubo ezisekwe emanzini kunye neengubo ezisekwe kuwo amanzi kunye nezinyibilikisiweyo zineengenelo zazo nezingalunganga. Ngenxa yokuba uphando ngamandla onxibelelwano olusekwe emanzini lusakhula, ukusebenza kwamanzi asekwe emanzini akunakuhlangabezana ngokupheleleyo neemfuno zemveliso yentlalo. Ukusetyenziswa kwengubo esele inyibilikisi kuseyimfuneko. Eyona meko ihlalutyelutyo kwaye igwetyiwe, kwaye ayinakuphinjwa ngenxa yokuphazamiseka okuthile kohlobo oluthile lwepeyinti. Kukholelwa ukuba ngenjongo yokwaleka kophando lwezenzululwazi kwi-caoats esekwe emanzini, ngenye imini, imihla ngemihla enobuhlobo kunye nemveliso ekhuselekileyo iya kusetyenziswa ngokubanzi kwikona nganye yomhlaba.
