Abavelisi beengubo bathi iingubo ezixutywa ngamanzi zibhekisela kwiingubo ezilungiselelwe ngee-emulsions njengezinto zokwenza ifilimu, apho ii-resin ezisekelwe kwi-solvent zinyibilika kwii-organic solvents, kwaye emva koko, ngoncedo lwee-emulsifiers, ii-resin zisasazwa emanzini ngokuxutywa okunamandla koomatshini ukwenza ii-emulsions, ezibizwa ngokuba yi-post-emulsion, zinokuxutywa ngamanzi ngexesha lokwakha.
Ipeyinti elungiselelwe ngokongeza inani elincinci le-emulsion kwi-resin enyibilikayo emanzini ayinakubizwa ngokuba yipeyinti ye-latex. Enyanisweni, ipeyinti enciphisa amanzi ayinakubizwa ngokuba yipeyinti ye-latex, kodwa ikwahlulwa njengepeyinti ye-latex ngokwendlela eqhelekileyo.
Iingenelo kunye nokungalungi kokwambathiswa okusekelwe emanzini
1. Ukusebenzisa amanzi njengesinyibilikisi kusindisa izixhobo ezininzi. Iingozi zomlilo ngexesha lokwakha ziyathintelwa kwaye ungcoliseko lomoya luyancitshiswa. Kusetyenziswa isixa esincinci kuphela se-alcohol ether organic solvent esingenatyhefu kangako, nto leyo ephucula iimeko zokusebenza.
2. Isinyibilikisi sendalo sepeyinti eqhelekileyo esekwe emanzini siphakathi kwe-10% kunye ne-15%, kodwa ipeyinti ye-cathodic electrophoretic yangoku incitshisiwe yaya ngaphantsi kwe-1.2%, nto leyo enefuthe elicacileyo ekunciphiseni ungcoliseko kunye nokonga izixhobo.
3. Uzinzo lokusasazeka ukuya kumandla oomatshini aqinileyo alukho semgangathweni. Xa isantya sokuhamba kombhobho wokuhambisa sahluka kakhulu, amasuntswana asasazekileyo acinezelwa abe ngamasuntswana aqinileyo, nto leyo eya kubangela ukuba kubekho imingxunya kwifilimu yokugquma. Kufuneka ukuba umbhobho wokuhambisa ube kwimeko entle kwaye udonga lombhobho lungabi naziphene.
4. Ingcolisa kakhulu izixhobo zokugquma. Izinto ezithintela ukugqwala okanye intsimbi engagqwaliyo ziyafuneka, kwaye iindleko zezixhobo ziphezulu. Ukugqwala kunye nokunyibilika kwesinyithi kumbhobho wokuhambisa kunokubangela ukuna kunye nokuqhekeka kwamasuntswana asasazekileyo kwifilimu yokugquma, ngoko ke nemibhobho yentsimbi engagqwaliyo nayo iyasetyenziswa.
Indlela yokugqiba ukusetyenziswa kunye nendlela yokwakha yabenzi bepeyinti
1. Lungisa ipeyinti ibe yi-spray viscosity efanelekileyo ngamanzi acocekileyo, uze ulinganise i-viscometer nge-Tu-4 viscometer. I-viscometer efanelekileyo idla ngokuba yimizuzwana emi-2 ukuya kwengama-30. Umenzi wepeyinti uthe ukuba akukho viscometer, ungasebenzisa indlela ebonakalayo yokuxuba ipeyinti ngentonga yesinyithi, uxube ukuya kubude obuyi-20 cm uze ume ukuze ubone.
2. Uxinzelelo lomoya kufuneka lulawulwe kwi-0.3-0.4 MPa kunye ne-3-4 kgf/cm2. Ukuba uxinzelelo luphantsi kakhulu, ipeyinti ayizukuba yi-atomi kakuhle kwaye umphezulu uya kuba nemingxunya. Ukuba uxinzelelo lukhulu kakhulu, kulula ukugoba, kwaye inkungu yepeyinti inkulu kakhulu ukuba ingachithi izinto kwaye ichaphazele impilo yabasebenzi bokwakha.
3. Umgama phakathi kwe-nozzle nomphezulu wento yi-300-400 mm, kwaye kulula ukugoba ukuba ikufutshane kakhulu. Ukuba ikude kakhulu, inkungu yepeyinti ayizukulingana kwaye kuya kubakho imingxuma. Kwaye ukuba inkungu ikude nomphezulu wento, inkungu yepeyinti iya kusasazeka endleleni, ibangele inkunkuma. Umenzi wepeyinti uthe umgama othile unokufunyanwa ngokohlobo lwepeyinti, i-viscosity kunye noxinzelelo lomoya.
4. Isibhamu sokutshiza singahamba phezulu nasezantsi, ekhohlo nasekunene, kwaye singahamba ngokulinganayo ngesantya se-10-12 m/min. Sifanele sithe tye kwaye sijonge ngqo kumphezulu wento. Xa kutshizwa kumacala omabini omphezulu wento, isandla esitsala i-trigger yesibhamu sokutshiza kufuneka sikhululwe ngokukhawuleza. Sivuliwe, oku kuya kunciphisa inkungu yepeyinti.
