Xa kuthelekiswa nezinye iipeyinti zokuphawula zendlela (ukunyibilika okushushu, ipeyinti ebandayo),iipeyinti zophawu lwendlela enamacandelo amabinizinezi mpawu zilandelayo:

Ixesha lokumisa lihambelana kuphela nobushushu be-ambient, ubuninzi be-agent ephilisayo, njl., kwaye akukho nto inxulumene nobukhulu befilimu yokugqoka.Oku kuvumela ipeyinti yophawu lwendlela enamacandelo amabini ukuba iyilwe ibe yifilim eshinyeneyo kunye nezinye iimpawu zendlela ezisebenzayo, ezifana namacandelo amabini oscillating oscillating oscillating wemvula ebusuku indlela ebonakalisa iimpawu zendlela, iimpawu ezinamachokoza, njl.njl.;

Impembelelo yokudibanisa i-cross-link in the marking film forming process iphucula kakhulu amandla omatshini wokumakisha ifilimu, ukunamathela kwindlela kunye namandla okudibanisa kwizinto ezibonakalayo;ezinye iindlela ezimbini zokumakisha iindlela zokumakisha zingasetyenziswa kwiindlela ezimanzi Ukunyanga, ngoko kunokusombulula imeko engathandekiyo yepeyinti yokumakisha indlela emvuleni.

Ngale ndlela, amanqaku amacandelo amabini aneenzuzo zawo ezizodwa xa kuthelekiswa nezinye iintlobo zokumakisha.Okulandelayo, ndiza kukwazisa amacandelo amaninzi aqhelekileyo kunye neempawu zawo.

Ukumakishwa kwamacandelo amabini e-epoxy

Iimpawu ze-epoxy zidla ngokusetyenziswa ukuzoba iipavumente ezinemibala ezingatyibilikiyo.Kuba i-epoxy resin ekrwada isezantsi ngexabiso eliphantsi, ixabiso lokumakishwa kwe-epoxy lisezantsi noko, kodwa ukunyangeka kwayo kubushushu obuphantsi.I-epoxy resin ifuna ukunyangwa kwiqondo lobushushu elingaphezulu kwe-10°C.Ukuba iphantsi kakhulu, ixesha lokunyanga liya kuba lide kakhulu.Ixesha lokunyanga liya kuba ngaphezu kweeyure ezisi-8 kubushushu obuphantsi obungaphantsi kwe-10℃.Le yeyona ngxaki inkulu ethintela ukusetyenziswa kweepoxy resin iindlela zokumakisha iindlela.Okwesibini, iimpawu zayo zokuguga zilula kakhulu kwaye zikhona kwiimolekyuli.Ibhondi ye-ether enephunga elimnandi iyaphulwa ngokulula phantsi kwe-irradiation yokukhanya kwe-ultraviolet, kunye nokuchasana kwemozulu yangaphandle kwefilimu yokugqoka ihlwempu.

I-polyurethane yokumakisha amacandelo amabini

Iimpawu zePolyurethane zikwasetyenziswa kwiipavumente ezinemibala.Inkqubo yokwakhiwa kwayo ifana ne-epoxy.Akuyi kugqithwa emva kokwakhiwa, kodwa ixesha lokunyanga lide kakhulu, ngokubanzi ngaphezu kweeyure ezingama-4-8.Iingubo ze-polyurethane zinokutsha kunye netyhefu ethile, ebangela iingozi ezithile ezifihlakeleyo kwimpilo kunye nokhuseleko lwabasebenzi bokwakha.Ngelo xesha, umxholo oqinileyo wezinto eziluhlaza ze-polyurethane zihluke kakhulu ngenxa yeendlela ezahlukeneyo, kwaye ukubunjwa kwe-solvent jikelele kuphakathi kwe-3% kunye ne-15%, okubangelwa iingubo ezigqityiweyo.Umahluko wamaxabiso ngetoni nganye ungaphezulu kwe-yuan ezili-10,000, kwaye imarike inombhodamo.

I-Polyurea yokumakisha amacandelo amabini

Ukumakishwa kwe-polyurea yinto e-elastic eveliswa yi-reaction ye-isocyanate component A kunye ne-cyano compound component B. Ngokuqhelekileyo isetyenziswa kwiipavements ezinemibala.Ifilimu yokugqoka i-polyurea iphilisa ngokukhawuleza, kwaye ifilimu inokuqulunqwa kwimizuzwana engama-50 yabahamba ngeenyawo, enokunciphisa kakhulu ixesha lokwakha., Kodwa isantya sokusabela sikhawuleza kakhulu, nto leyo ebangela ubunzima obuthile bokwakha.Isetyenziselwa kakhulu ukutshiza kwaye ifuna ubuchwepheshe obuphezulu bokutshiza.Eyona ntsilelo icacileyo kukuba iyabiza kwaye iyabiza.

Ukumakishwa kwamacandelo amabini e-MMA

I-MMA yokumakishwa kwamacandelo amabini ayinakuzoba iindlela ezinemibala kuphela, kodwa kunye nemigca ephuzi kunye nemhlophe.Inoluhlu olubanzi lwezicelo.Inezi ncedo zilandelayo:

1. Isantya sokoma sikhawuleza kakhulu.Ngokuqhelekileyo ixesha lokunyanga liyi-3 ~ 10min, kwaye indlela iya kubuyiselwa kwi-traffic ngexesha elifutshane lokwakha.Nangona kwindawo yokushisa ephantsi, inani le-ejenti yokunyanga linganyuswa ngokufanelekileyo ngokohlobo lwe-resin, kwaye ukunyangwa kunokufezekiswa kwi-5 ° C kwi-15 ~ 30min.

2. Ukusebenza okugqwesileyo.

① Ukuba bhetyebhetye okulungileyo.Ukuguquguquka okuyingqayizivele kwe-methyl methacrylate kunokuphepha ukwenzeka kokuqhekeka kwefilimu yokumakisha.

②Ukunamathela okugqwesileyo.Ubunzima bemolekyuli obuphantsi bepolima esebenzayo bunokungena kakuhle kwiicapillaries ezishiyekileyo kwipavumente, kwaye inokusombulula ingxaki yokuba ezinye iipeyinti zokumakisha azidityaniswa lula kunye neepavumente zesamente zekhonkrithi.

③Ukumelana nokukrazuka okukhulu.I-polymerization reaction yenkqubo yokwenza ifilimu yenza i-network ye-molecular structure, edibanisa ngokuqinileyo amacandelo ahlukeneyo kwi-coating ibe yi-dense yonke.

④Ukumelana nemozulu elungileyo.Ukumakishwa akuvelisi ukuphuka kweqondo eliphantsi lobushushu okanye ukuthambisa okuphezulu, kwaye akukho phantse ukuguga ngexesha lokusetyenziswa;amacandelo amabini enza imolekyuli entsha yothungelwano emva kokwenziwa kwepolymerization, eyipolymer enkulu yobunzima bemolekyuli, kwaye imolekyuli entsha ayinazo iibhondi zemolekyuli ezisebenzayo.

3. Iimpawu eziphakamileyo zokusingqongileyo.

Ukunyibilika kwe-solvent kuya kutshabalalisa umaleko we-ozone emoyeni kwaye kubangele iingxaki ezinzulu zokusingqongileyo.Xa kuthelekiswa nepeyinti yokumakisha yendlela enye, iipeyinti ezimbini ze-acrylic zinyangwa yi-polymerization yeekhemikhali, kunokuba i-volatilization yomzimba kunye nokomisa.Kukho phantse i-solvent kwi-system, kuphela inani elincinci le-monomer volatilization eyenzekayo ngexesha lokwakhiwa (ukuvuselela, ukugubungela), kwaye ukukhutshwa kwe-solvent kuphantsi kakhulu kune-solvent-based marking peyinti.
