Pente ea matšoao a litsela tsa boema-fofane e hloka maemo a holimo haholo, hobane ha e tlameha feela ho mamella litlamorao tse matla tsa ho tloha le ho lula ha lifofane, khohlano ea mabili (e hlahisang mocheso o phahameng le ho bontša matla a matla a ho petsoha), empa hape le litlamorao tsa nako e telele tsa boima ba lifofane, mahlaseli a ultraviolet, pula, tšilafalo ea mafura le ho feto-fetoha ha mocheso. Ka hona, ho khetha pente e nepahetseng ea matšoao ho bohlokoa bakeng sa litsela tsa boema-fofane. Ho na le mefuta e mengata ea lipente tsa matšoao 'marakeng, joalo ka acrylic e thehiloeng metsing, acrylic e thehiloeng ho solvent, thermoplastic road coating, le pente ea likarolo tse peli ea matšoao a litsela (MMA) jj., har'a tse ling. Ho khetha pente e nepahetseng ho ka ba boima haholo. Sengoloa sena se tla hlahloba pente e tloaelehileng ea matšoao le ho u tataisa hore na u ka khetha pente e ntle ka ho fetisisa joang bakeng sa merero ea hau ea litsela tsa boema-fofane.
Ho tšoaea litsela tsa boemafofane ho latela maemo a itseng a indasteri. Ho ea ka Tsamaiso ea Lifofane tsa Sechaba ea Chaena ea morao-rao ea "Litlhaloso tsa Tekheniki bakeng sa Tlhokomelo ea Motheo ea Libaka tsa Lifofane tsa Boema-fofane" (MH/T 5086-2025), pente ea ho tšoaea litsela ea mofuta oa thermoplastic e thibetsoe bakeng sa matšoao a litsela tsa boema-fofane libakeng tsa mesebetsi ea boema-fofane. Hona joale, pente ea ho tšoaea litsela ea acrylic e thehiloeng metsing e khothaletsoa haholo bakeng sa ho tšoaea litsela tsa boema-fofane, e thehiloeng ho solvent kapa likarolo tse peli le eona e ka nahanoa boemong bo itseng. Ka tlase ke papiso ea mefuta ea tsona:
1. Pente ea ho Tšoaea Litsela ea Acrylic e Thehiloeng Metsing
Pente ea ho tšoaea litsela ea acrylic e thehiloeng metsing ke e sireletsang tikoloho. E entsoe ka emulsion ea acrylic e thehiloeng metsing, li-pigment, li-filler, metsi, lithuso tsa ho etsa filimi, jj., 'me ha e kotsi hakaalo tikolohong ha e bapisoa le pente ea ho tšoaea litsela e thehiloeng ho solvent. Pente ena e omella kapele, e potlakisa kaho le ho fokotsa nako ea ho lieha.
Likaroloana:
- VOC e Tlase: Foromo e thehilweng metsing, mesi e fokolang e tswang metswakong e feto-fetohang ya manyolo (VOCs), basebetsi ba kaho ba tikoloho e mosa le tikoloho.
- Ho Omisa ka Potlako: Bakeng sa boema-fofane, ho omisa ka potlako ho bohlokoa hobane boema-fofane bo tlameha ho fokotsa nako ea ho koaloa ha litsela tsa ho matha.
- Ho bonolo ho e sebelisa: Tšehetsa borashe/rolara/spray, e leng se etsang hore ho be bonolo hore borakontraka ba bangata ba e sebelise.
Tlhahlobo ea Tšebeliso: E khothaletsoa haholo; hona joale mofuta ona ke o sebelisoang haholo boema-fofaneng ka hare ho naha le machabeng (o latela maemo a machaba a kang US FAA P-620).
2. Pente ea ho Tšoaea Litsela e Thehiloeng ho Solvent
Pente ea ho tšoaea litsela e thehiloeng ho solvent ke khetho ea setso e 'nileng ea sebelisoa ka lilemo tse ngata. E entsoe ka resin ea acrylic, li-solvent tsa organic, li-pigment, li-filler le li-additives, 'me e tsebahala ka ho tšoarella ha eona le ho hanyetsa ho khoptjoa. Ka lebaka la bophelo ba eona bo bolelele ba tšebeletso, hangata ke khetho ea pele bakeng sa libaka tse nang le sephethephethe se seholo, ho kenyeletsoa le litsela tsa boema-fofane.
Likaroloana:
- Ho Tšoarella Haholo: Pente e thehiloeng ho solvent e ka mamella maemo a leholimo a thata le sephethephethe se phahameng, e leng se etsang hore e be e loketseng litsela tsa ho matha.
- Ho khomarela ka bokhabane: Mofuta ona oa pente o khomarela hantle libakeng tse fapaneng, o netefatsa hore matšoao a bonahala nako e telele.
- Botsoalle bo Fosahetseng ba Tikoloho
Tlhahlobo ea Tšebeliso: Haeba litlhoko tsa tikoloho li se holimo, le tsona li khothaletsoa haholo.
3. Pente ea ho Tšoaea Litsela ea MMA (Methacrylic Acid)
MMA ke pente e tšoaeang mela e nang le likarolo tse peli. E entsoe ka resin ea methyl methacrylate (MMA), likarolo tse peli (A le B), li-pigment, li-filler, li-glass beads, jj.
Likaroloana:
- Ho hanyetsa ho kgopama le ho khomarela ho hoholo haholo, thepa e bontshang nako e telele
- E loketse libaka tse nang le litlhoko tse phahameng tsa ho tšoarella
- Tšebeliso e rarahaneng: Ho kopanya likarolo tse peli sebakeng seo ho hloka lisebelisoa le lits'ebetso tse khethehileng, 'me theko le eona e theko e boima ho feta mofuta oa tse ling.
Tlhahlobo ea Tšebeliso: Ka lebaka la litlhoko tsa ho kopanya sebakeng seo, litlhoko tse phahameng tsa lisebelisoa le ts'ebetso, le litšenyehelo tse phahameng, ho se bonolo ho li romella khoebong ea machabeng, ke khetho e khethiloeng haeba tekanyetso e lekaneng 'me e na le lisebelisoa tsa ts'ebeliso ea litsebi le lihlopha.
4. Pente ea ho Tšoaea Tsela ea Thermoplastic
Letshwao la tsela la thermoplastic ke pente ya ho tšoaea phofo. E entswe ka resin ya peterole ya C5, di-pigment, di-filler, di-glass beads, di-plasticizer, jj. Ke phofo e tiileng mochesong wa kamore, empa e hloka ho futhumatswa ho fihlela ho 180℃-220℃ ho qhibilihisa mokelikeli ke mochini o ikgethang nakong ya kaho. Ebe e hohla kapa e fafatswa hodima tsela mme e etsa kristale hore e be filimi kamora ho phodisa. Hobane theko ya thepa e tala e tlase, e sebediswa haholo ditseleng tsa ditoropo.
Likaroloana:
- Litšenyehelo tse tlase: Litšenyehelo tse tlase tsa thepa e tala le tsa kaho
- Seaparo se teteaneng se fana ka matla a motheo a sebopeho
- E sekametse ho nolofala le ho petsoha
Tlhahlobo ea Tšebeliso: Tšebeliso ea eona e thibetsoe ka tieo ka lebaka la likotsi tsa FOD tseo e li bakang; e thibetsoe ka ho hlaka ke Tsamaiso ea Lifofane tsa Sechaba ea Chaena.
Ho latela kutloisiso e kaholimo ea lipente tsa ho roala, pente ea ho tšoaea litsela tsa boema-fofane le eona e hloka ho nahana ka ho lumellana le ho roala hape. Tlhokomelong ea lipente tsa ho roala, ho lumellana pakeng tsa lipente tse ncha le tsa khale ho bohlokoa. Ho ea ka melaoana, ke lipente tse thehiloeng metsing feela tse ka koaheloang hape holim'a mofuta ofe kapa ofe oa pente ea khale, empa lipente tsa ho tšoaea litsela tse thehiloeng ho solvent le tse peli (MMA) li ke ke tsa koaheloa hape ka mokhoa o sa reroang meleng ea khale e sa lumellaneng, ho seng joalo ho tla lebisa ho peoeng. Lena ke le leng la mabaka a bohlokoa a hore na ke hobane'ng ha lipente tse thehiloeng metsing e le khetho e khethiloeng. Ena hape ke tharollo e sireletsehileng ka ho fetisisa, haholo-holo e lumellanang le maemo a FAA P-620.
Ho feta moo, tekano pakeng tsa tshebetso le ditjeo le yona ke ntlha ya bohlokwa. Le hoja dipente tsa ho tshwaya ditsela tse nang le dikarolo tse pedi (MMA) di na le tshebetso e betere, ho rarahana ha tshebediso ya tsona le ditjeo le tsona di phahame ka ho fetisisa. Bakeng sa dibaka tsa mantlha tsa difofane tse nang le sephethephethe se seholo, MMA, ka ho tshwarella ha yona ho hoholo le thepa e bontshang nako e telele, ke kgetho e ntle ka ho fetisisa; athe bakeng sa diteksi kapa di-aprone tse akaretsang, dipente tse thehilweng metsing ke kgetho e ntle ka ho fetisisa, ka lebaka la boiketlo ba tsona, tikoloho e mosa, le tshebetso e lekaneng, e ba kgetho e theko e tlase le e sebetsang ka ho fetisisa.
Mona ke lintlha tse ling tseo u lokelang ho li nahana ha u khetha pente ea matšoao a litsela tsa boema-fofane:
1. Phallo le Mofuta oa Sephethephethe: Phallo le mofuta oa sephethephethe lebaleng la lifofane ke lintlha tsa bohlokoa ho khethoeng ha pente e loketseng. Libaka tsa lifofane tse nang le sephethephethe se seholo li ka hloka pente e tšoarellang haholoanyane, joalo ka pente e thehiloeng ho solvent kapa e khethehileng ea lifofane, ho mamella ho senyeha ha lifofane.
2. Mokhoa oa ho Sebelisa: Mokhoa oa ho Sebelisa o boetse o ama khetho ea pente. Lipente tse ling li hloka lisebelisoa tse khethehileng, ha tse ling li ka sebelisoa ho sebelisoa mechine e tloaelehileng ea ho tšoaea litsela. Netefatsa hore pente e khethiloeng e lumellana le lisebelisoa tse seng li ntse li le teng.
3. Ho Latela Melao: Maema-fofane a tlameha ho latela melao e thata mabapi le matšoao a litsela tsa sefofane. Ho khetha pente e fihlelang maemo a bolaoli ba lifofane ho bohlokoa ho netefatsa hore matšoao aa latela ebile a bolokehile.
4. Tekanyetso: Qetellong, lithibelo tsa tekanyetso li tla bapala karolo ea bohlokoa ts'ebetsong ea ho etsa liqeto. Le hoja liphahlo tse khethehileng tsa litsela tsa ho palama li ka fana ka ts'ebetso e phahameng, li ka boela tsa bitsa chelete e ngata. Ho leka-lekanya litšenyehelo, ts'ebetso le polokeho ke tsa bohlokoa.
Ho khetha pente e nepahetseng ea ho tšoaea tsela bakeng sa lebala la lifofane la boema-fofane ke qeto ea bohlokoa e amang ka ho toba polokeho le katleho ea ts'ebetso. Haeba hajoale u batla pente e loketseng projeke ea hau ea ho tšoaea litsela tsa lifofane tsa boema-fofane, etsa tlhahiso ea hore u khethe pente ea ho tšoaea ea acrylic e thehiloeng metsing ea Forest Paint, 'me ba boetse ba fana ka lisampole tsa mahala bakeng sa liteko.
