Kuenzaniswa nemamwe mapendi emigwagwa (inopisa inonyungudika, pendi inotonhora),mativi maviri emugwagwa anomaka pendiIva nezvinhu zvinotevera zvinoshamisa:

Nguva yekuomeswa inongobatana chete neambient tembiricha, kuwanda kweanorapa agent, nezvimwewo, uye haina chekuita nehukobvu hwefirimu yekuputira.Izvi zvinobvumira pendi ine zvikamu zviviri zvemugwagwa kuti igadziriswe kuita firimu gobvu uye mamwe makiyi emumugwagwa anoshanda, akadai sezvikamu zviviri-zviviri zvinotsvukisa mvura inonaya usiku inoratidzira mamaki emugwagwa, mavanga ane madoti, nezvimwewo;

Iko kuchinjika kwekubatanidza mucherechedzo wekugadzira firimu inovandudza zvakanyanya simba remakanika reiyo yekumaka firimu, kunamatira kumugwagwa wepamusoro uye kusimba kwekubatanidza kune inofungidzira zvinhu;zvimwe zvikamu zviviri zvemumugwagwa zvekumaka mabhanhire zvinogona kushandiswa mumigwagwa yakanyorova Kurapa, saka inogona kugadzirisa mamiriro asina kunaka emugwagwa wekumaka pendi mumvura inonaya.

Neiyi nzira, maviri-zvikamu mamaki ane zvawo akasiyana mabhenefiti kana achienzaniswa nemamwe marudzi emakamaka.Tevere, ini ndichasuma kwauri akati wandei akajairwa maviri-chikamu mamaki uye maitiro avo.

Epoxy maviri-chikamu chekumaka

Epoxy markings anowanzo shandiswa kudhirowa mavara asina-kutsvedza pavements.Sezvo iyo mbishi epoxy resin isingadhuri, mutengo weiyo epoxy mamaki wakadzikira, asi kudzika-tembiricha kwayo kwakashata.Iyo epoxy resin kazhinji inoda kurapwa patembiricha iri pamusoro pe10°C.Kana yakanyanya kuderera, nguva yekurapa ichave yakareba.Nguva yekurapa ichave inopfuura maawa masere pane yakaderera tembiricha iri pasi pe10 ℃.Iri ndiro dambudziko guru rinorambidza kushandiswa kwe epoxy resin road marking coatings.Chechipiri, chiedza chayo chekuchembera zvimiro zvakare chine hurombo uye chiripo mumamorekuru.Iyo inonhuwira ether bond inoputsika nyore pasi pekuvhenekesa kwechiedza che ultraviolet, uye kunze kwekupikisa kwekunze kwefirimu yekuputira kwakashata.

Polyurethane maviri-chikamu chekumaka

Polyurethane markings anoshandiswawo pamapavha ane mavara.Kuvaka kwayo kwakafanana neye epoxy.Iyo haizofukidzwe mushure mekuvaka, asi nguva yekurapa yakarebesa, kazhinji inopfuura maawa 4-8.Polyurethane coatings ine kumwe kupisa uye chepfu, izvo zvinokonzeresa dzimwe njodzi dzakavanzika kuhutano nekuchengetedzeka kwevashandi vekuvaka.Panguva imwecheteyo, iyo yakasimba yemukati ye polyurethane raw materials yakasiyana zvakanyanya nekuda kwezvakasiyana maumbirwo, uye general solvent kuumbwa kuri pakati pe3% ne15%, zvichikonzera kupedzwa kwekuputira.Musiyano wemutengo patani unodarika zviuru gumi zveyuan, uye musika une bongozozo.

Polyurea maviri-chikamu chekumaka

Polyurea marking is an elastic substance inogadzirwa nekuita kwe isocyanate component A uye cyano compound component B. Inowanzoshandiswa pamapavement ane mavara.Iyo polyurea coating film inoporesa nekukurumidza, uye firimu rinogona kuumbwa mumasekondi makumi mashanu kune vanofamba netsoka, izvo zvinogona kupfupisa zvakanyanya nguva yekuvaka., Asi kumhanya kwekuita kwakakurumidza, izvo zvinokonzeresa kumwe kuoma kwekuvaka.Inonyanya kushandiswa pakupfapfaidza uye inoda tekinoroji yepamusoro yekufirita.Chinhu chinonyanya kuipa ndechokuti inodhura uye inodhura.

MMA maviri-chikamu chekumaka

MMA mbiri-chikamu chekumaka haigone chete kudhirowa migwagwa ine mavara, asiwo yero uye chena mitsetse.Iine huwandu hwakawanda hwekushandisa.Iine zvinotevera zvakanakira:

1. Kuomeswa kwemvura kunokurumidza kukurumidza.Kazhinji nguva yekurapa ndeye 3 ~ 10min, uye mugwagwa unozodzoserwa kune traffic mukati menguva pfupi yekuvakwa.Kunyangwe munzvimbo yakadzika tembiricha, huwandu hweanorapa hunogona kuwedzerwa zvakakodzera zvichienderana nerudzi rweresin, uye kurapa kunogona kuwanikwa pa5 ° C kwe15 ~ 30min.

2. Kuita kwakanakisa.

① Kunaka kuchinjika.Iyo yakasarudzika inoshanduka yemethyl methacrylate inogona kudzivirira kuitika kwekutsemuka kweiyo yekumaka firimu.

②Kunamira zvakanaka.Iyo yakaderera molecular huremu inoshanda polymer ine yakanaka kupenya kune macapillaries akasara pane yakarongwa, uye inogona kugadzirisa dambudziko rekuti mamwe mapendi ekumaka haasanganiswe nyore nesamende kongiri pavements.

③Super abrasion kuramba.Iyo polymerization maitiro eiyo firimu yekugadzira maitiro inoumba network mamorekuru chimiro, iyo inosanganisa zvakasimba izvo zvakasiyana-siyana zviri mujasi kuita dense yakazara.

④Kuramba kwakanaka kwemamiriro ekunze.Iko kucherekedza hakubudisi kutsika-kutsemuka kutsemuka kana kunyorova kwepamusoro, uye panenge pasina kuchembera panguva yekushandiswa;zvikamu zviviri izvi zvinoumba mamorekuru matsva etiweki mushure mepolymerization, inova hombe yemamorekuru huremu hwepolymer, uye iyo molecule itsva haina chero inoshanda mamorekuru mabhondi.

3. High kuchengetedzwa kwezvakatipoteredza maitiro.

Solvent volatilization ichaparadza iyo ozone layer uye kukonzera matambudziko makuru ezvakatipoteredza.Kuenzaniswa nechikamu chimwe-chikamu chekumaka pendi, maviri-chikamu acrylic pendi inoporeswa nemakemikari polymerization, pane kuvhurika kwemuviri uye kuomesa.Iko kune inenge isina solvent muhurongwa, zvishoma chete zvishoma zvemonomer volatilization inoitika panguva yekuvaka (kubvongodza, kuvhara), uye kubudiswa kwe solvent kwakaderera kudarika solvent-based road marking pendi.
