Pendi yezviratidzo zvenhandare yendege inoda mwero wepamusoro-soro, nekuti haingofanire kungotsungirira kukanganiswa kwakanyanya kwendege dzinosimuka nekumhara, kukweshana kwematayi (zvichikonzera kupisa kwakanyanya uye zvichiratidza simba rakasimba rekudonha), asiwo mhedzisiro yenguva refu yehuremu hwendege, mwaranzi ye ultraviolet, mvura, kusvibiswa kwemafuta, uye kushanduka kwekushisa. Nokudaro, kusarudza pendi yezviratidzo zvakakodzera kwakakosha kune nhandare dzendege. Kune mhando dzakawanda dzependi dzezviratidzo dziri pamusika, dzakadai se water-based acrylic, solvent-based acrylic, thermoplastic road coating, uye two component road marking paint (MMA) nezvimwewo, pakati pezvimwe. Kusarudza pendi chaiyo kunogona kunetsa. Chinyorwa chino chichaongorora pendi yezviratidzo yakajairika uye chichakutungamira kuti ungasarudza sei pendi yakanakisa yemapurojekiti ako enhandare dzendege.
Kuisa chiratidzo chemigwagwa yendege panhandare yendege kunotevera mitemo yakatarwa yeindasitiri. Sekureva kweCivil Aviation Administration yeChina's latest "Technical Specifications for Basic Maintenance of Civil Airport Flight Areas" (MH/T 5086-2025), pendi yekuisa chiratidzo chemugwagwa yemhando yethermoplastic haibvumidzwe pakuisa chiratidzo chemigwagwa yendege munzvimbo dzenhandare yendege. Parizvino, pendi yekuisa chiratidzo chemugwagwa yeacrylic inobva mumvura inonyanya kukurudzirwa pakuisa chiratidzo chemigwagwa yendege panhandare yendege, ine solvent-based kana kuti ine zvikamu zviviri zvinogonawo kutariswa mumamiriro ezvinhu chaiwo. Pazasi pane kuenzanisa kwemhando dzacho:
1. Pendi yeAcrylic Road Marking Pendi yemvura
Pendi yekuisa migwagwa yeacrylic yakagadzirwa nemvura inobatsira zvakatipoteredza. Yakagadzirwa ne emulsion yeacrylic yakagadzirwa nemvura, pigments, fillers, mvura, aids dzinogadzira firimu, nezvimwewo, uye haina kukuvadza nharaunda zvichienzaniswa nependi yekuisa migwagwa yeacrylic yakagadzirwa nemvura. Pendi iyi inooma nekukurumidza, ichikurumidzisa kuvaka uye ichideredza nguva yekunonoka.
Zvimiro:
- VOC Yakaderera: Fomura inobva mumvura, kuburitsa kushoma kwemakemikari anoshanduka kuita organic (VOCs), vashandi vekuvaka nharaunda vane hushamwari uye nharaunda.
- Kuomesa Nokukurumidza: Kune nhandare dzendege, kuomesa nekukurumidza kwakakosha nekuti nhandare dzendege dzinofanira kuderedza nguva yekuvharwa kwenhandare dzendege.
- Zviri Nyore Kuisa: Tsigira bhurashi/roller/spray, zvichiita kuti zvive nyore kune vakawanda vanogadzira mapuranga kushandisa.
Kuongorora Kushandiswa: Inokurudzirwa zvikuru; iyi ndiyo mhando inoshandiswa zvakanyanya pari zvino munhandare dzendege munyika nekunze kwenyika (inoenderana nezvinodiwa pasi rose zvakaita seUS FAA P-620).
2. Pendi yeMigwagwa Inoshandiswa Pakunyungudutsa
Pendi yekuisa chiratidzo chemugwagwa ine solvent isarudzo yechinyakare yagara ichishandiswa kwemakore mazhinji. Inoumbwa ne acrylic resin, organic solvents, pigments, fillers, uye additives, uye inozivikanwa nekugara kwayo kwenguva refu uye kuramba kukwesha. Nekuda kwehupenyu hwayo hurefu hwekushanda, inowanzova sarudzo yekutanga munzvimbo dzine vanhu vakawanda, kusanganisira nzira dzendege.
Zvimiro:
- Kugara Kwenguva Yakareba: Pendi dzinonyungudika dzinogona kutsungirira mamiriro ekunze akaoma uye kuwanda kwemotokari, zvichiita kuti dzive dzakakodzera nzira dzekumhanya nendege.
- Kunamira Kwakanaka: Rudzi urwu rwependi runonamira zvakanaka panzvimbo dzakasiyana-siyana, zvichiita kuti zviratidzo zvionekwe kwenguva refu.
- Kusava neushamwari pakati pezvakatipoteredza
Kuongorora Kushandiswa: Kana zvinodiwa zvakatipoteredza zvisina kukwira, zvinokurudzirwawo zvikuru.
3. Pendi yeMMA (Methacrylic Acid) yeKuisa Zviratidzo Mumugwagwa
MMA ipendi ine zvikamu zviviri inoratidza mitsetse. Iine resin yemethyl methacrylate (MMA), zvikamu zviviri (A naB), pigments, fillers, glass beads, nezvimwewo.
Zvimiro:
- Inodzivirira zvakanyanya kukwenya uye inonamatira, ine hunhu hunogara kwenguva refu hwekuratidzira
- Yakakodzera nzvimbo dzine zvinodiwa zvekugara kwenguva refu
- Kushandiswa kwakaoma: Kusanganisa zvinhu zviviri panzvimbo iyi kunoda michina yakakosha uye maitiro, uye mutengo wacho unodhurawo kupfuura mamwe marudzi.
Kuongororwa Kwekushandisa: Nekuda kwezvinodiwa zvekusanganisa panzvimbo, zvinodiwa zvemichina yakawanda uye maitiro, uye mitengo yakakwira, zvisiri nyore kutumira mukutengeserana kwenyika dzese, isarudzo inosarudzwa kana bhajeti yakakwana uye ine michina yehunyanzvi yekushandisa uye mapoka.
4. Pendi yekuisa chiratidzo chemugwagwa weThermoplastic
Kuisa chiratidzo chemugwagwa muThermoplastic ipendi yekuisa chiratidzo cheupfu. Inogadzirwa neC5 petroleum resin, pigments, fillers, glass beads, plasticizers, nezvimwewo. Ihupfu hwakasimba patembiricha yemumba, asi hunoda kupiswa kusvika 180℃-220℃ kuti hunyunguduke kuita mvura nemuchina wakakosha panguva yekuvaka. Inozokweshwa kana kupfapfaidzwa pamusoro pemugwagwa yoita crystallize kuita firimu mushure mekutonhodza. Nekuti mutengo wezvinhu zvakabikwa wakaderera, inonyanya kushandiswa mumigwagwa yemaguta.
Zvimiro:
- Mutengo wakaderera: Mari shoma yezvinhu zvakabikwa uye yekuvaka
- Kupfeka kwakakora kunopa simba guru rekuvaka
- Inowanzo pfava uye kutsemuka
Kuongorora Kushandiswa Kwayo: Kushandiswa kwayo kwakarambidzwa zvachose nekuda kwenjodzi dzayo dzeFOD; yakarambidzwa zvakajeka neCivil Aviation Administration yeChina.
Zvichibva pakunzwisisa kwataurwa pamusoro apa nezvekupeta, pendi yekuisa chiratidzo pamugwagwa wendege inofanirawo kufunga nezvekuenderana uye kuisazve chifukidziro. Mukugadzirisa nzira dzendege, kuwirirana pakati pekuisa chifukidziro chitsva nechekare kwakakosha. Zvinoenderana nemitemo, pendi dzemvura chete ndidzo dzinogona kupetazve pamusoro pechero rudzi rwekuisa chifukidziro chekare, asi pendi dzekuisa chiratidzo pamugwagwa dzine solvent uye mbiri-component (MMA) hadzigone kupetazve pamitsetse yekare isingaenderane, zvikasadaro zvichaita kuti pave nekukweshwa. Ichi ndicho chimwe chezvikonzero zvakakosha nei pendi dzemvura dziri sarudzo inosarudzwa. Iyi ndiyo mhinduro yakachengeteka, inoenderana neFAA P-620 standards.
Uyezve, kuenzana pakati pekushanda nemutengo chinhu chakakoshawo. Kunyangwe pendi dzekupaka migwagwa (MMA) dzine zvikamu zviviri dzichishanda zviri nani, kuomarara kwekushandiswa kwadzo uye mutengo wadzo zvakanyanya. Kune nzvimbo dzepakati penzira dzinofamba nemotokari, MMA, ine kugara kwayo kwenguva refu uye hunhu hunogara kwenguva refu hunoratidza chiedza, ndiyo sarudzo yakanakisa; nepo kune nzira dzekutakura vanhu kana maapuroni, pendi dzinobva mumvura ndiyo sarudzo yakanakisa, nekuda kwekureruka kwadzo, hushamwari hwezvakatipoteredza, uye kushanda kwakakwana, dzinova sarudzo inodhura zvakanyanya uye inoshanda.
Heano mamwe matinofanira kufunga nezvawo pakusarudza pendi yekuisa chiratidzo panhandare yendege:
1. Kufamba Kwemotokari Nerudzi: Kufamba kwemotokari nerudzi rwenzira yekumhanyira ndiyo nzira huru yekusarudza pendi yakakodzera. Nzira dzekumhanyira dzinofamba nemotokari dzakawanda dzingada pendi dzakasimba, dzakadai sependi dzinonyungudutsa mvura kana kuti pendi dzakagadzirwa nemaoko, kuti dzisaparare nekusakara kwendege.
2. Nzira Yokushandisa: Nzira yekushandisa inokanganisawo kusarudzwa kwependi. Mamwe mapendi anoda michina yakasarudzika, nepo mamwe anogona kushandiswa uchishandisa michina yekuisa chiratidzo chemugwagwa. Iva nechokwadi chekuti pendi yakasarudzwa inoenderana nemidziyo iripo.
3. Kutevedzera Mutemo: Nhandare dzendege dzinofanira kutevedzera mitemo yakasimba ine chekuita nezviratidzo zvemumugwagwa. Kusarudza pendi inoenderana nezvinodiwa nevakuru vendege kwakakosha kuti zvive nechokwadi chekuti zviratidzo zvacho zvinoenderana uye zvakachengeteka.
4. Bhajeti: Chekupedzisira, zvirambidzo zvebhajeti zvichabatsira zvikuru pakuita sarudzo. Kunyange zvazvo machira ekudzivirira migwagwa yendege akakosha achigona kupa mashandiro akanaka, anogonawo kudhura zvakanyanya. Kuenzanisa mutengo, mashandiro, uye kuchengetedzeka kwakakosha.
Kusarudza pendi yekuisa chiratidzo chemugwagwa chaiyo yenhandare yendege chisarudzo chakakosha chinokanganisa kuchengetedzeka uye kushanda zvakanaka. Kana uri kutsvaga pendi yakakodzera chirongwa chako chekuisa chiratidzo chenhandare yendege, ipa zano rekusarudza pendi yekuisa chiratidzo chemvura yeForest Paint, uye vanopawo sampuro dzemahara dzekuyedza.
