Liphaephe tsa polyurethane li phahame-liphaephe tsa indasteri tse sebetsang hantle haholo tse entsoeng ka resin ea polyurethane. Ka lebaka la thepa ea bona e ntle ea mochini, khanyetso ea kutu ea lik'hemik'hale, le ho ikamahanya le maemo a tikoloho, li sebelisoa haholo mafapheng a fapaneng. Sengoliloeng sena se tla kenyelletsa ka mokhoa o hlophisehileng litšobotsi tsa tekheniki le boleng bo sebetsang ba li-tubes tsa polyurethane ho tsoa likarolong tsa thepa ea thepa, lits'ebetso tsa tlhahiso, lits'ebetso tsa mantlha, le mekhoa ea nts'etsopele.
I. Litšobotsi tsa Boitsebiso le Melemo ea Ts'ebetso
Thepa ea mantlha ea polyurethane tubes ke polyurethane (PU), e phahameng-motsoako oa limolek'hule o hlahisoang ke polymerization reaction ea polyols le isocyanates, ho kopanya elasticity ea rabara le matla a polasetiki. Lintho tsa eona tsa bohlokoa li kenyelletsa:
1. High Abrasion Resistance: Ho hanyetsa ha abrasion ea li-tubes tsa polyurethane ke makhetlo a 3-5 a rabara ea tlhaho, e leng se etsang hore e tšoanelehe bakeng sa maemo a lipalangoang tsa mokelikeli o nang le likhohlano tse phahameng le tšusumetso e phahameng, tse kang liphaephe tsa hydraulic mechineng ea merafo le ea boenjiniere.
2. Chemical Corrosion Resistance: E hanyetsana hantle le li-acids tse ngata, alkalis, matsoai, le metsoako ea organic, 'me e tsitsitse ka ho khetheha tikolohong eo e seng{1}}e se nang matla a oxidizing.
3. Ho Fetolana le Boemo ba Boemo ba Leholimo: E boloka ho feto-fetoha ha maemo esita le mocheso o tlase (hangata o mamella -40℃ho 80℃), 'me e bonts'a khanyetso e phahameng ea botsofali ea UV ha e bapisoa le li-hose tse tloaelehileng tsa rabara.
4. Boima bo Bobebe le Matla a Holimo: Ka boima ba 1/8 feela ba liphaephe tsa tšepe, e ka mamella likhatello tse phatlohileng tsa 20-30 MPa, e leng se etsang hore e tšoanelehe bakeng sa lisebelisoa tse thibelang boima ba 'mele.
II. Production Process and Technology Classification Lithapo tsa Polyurethane li hlahisoa ka mokhoa oa extrusion molding, ka mokhoa o ikhethileng ho kenyeletsoa prepolymerization ea lintho tse tala, ho kopanya le ho etsa polasetiki, sebopeho sa hlobo, le ho sebetsa{1}}ka poso. Ho latela liphapang tsa sebopeho, li ka aroloa ka mekhahlelo e 'meli e latelang:
1. Li-hose tse le 'ngoe- tse entsoeng ka polyurethane: E loketse lipalangoang tse tloaelehileng tse tlase- tse nang le litjeo tse tlase, empa khatello ea hae e sa khonehe.
2. Li-hose tse entsoeng ka polyurethane: Fumana mesebetsi e mengata ho kopanyelletsa le ho hanyetsa khatello e phahameng, ho se khone ho sesa, le ho thibela ho taboha ka har'a lesela le ka hare-le sa tsitsang, lesela le matlafatsang le mahareng (joalo ka terata ea spiral kapa fiber braided layer) le lesela le ka ntle le sireletsang. E sebelisoa hangata ho-litsamaiso tse phahameng tsa khatello ea metsi.
Ho feta moo, li-hose tse ling tse khethehileng-li-purpose polyurethane li fetotsoe ka li-flame retardants, antistatic agents, le li-additives tse ling ho finyella litekanyetso tsa polokeho liindastering tse kang tsa petrochemical le morafo oa mashala.
III. Libaka tse Tloaelehileng tsa Ts'ebeliso Li-tubing tsa polyurethane, tse nang le melemo ea ts'ebetso e felletseng, li bapala karolo ea bohlokoa libakeng tse latelang:
1. Industrial Hydraulic Systems: E sebelisoa e le-liphaephe tsa oli tse hatellang haholo kapa lithapo tsa moea tse kenang mochining oa boenjineri, lisebelisoa tsa metallurgical, le methapo e itirisang ea tlhahiso, e nkela liphaepe tsa khale tsa rabara ho lelefatsa tšebeletso.
2. Sepalangoang sa Metsi: Se sebelisoa indastering ea lik'hemik'hale, lijo, le meriana ho tsamaisa lintho tse senyehang kapa{1}}li metsi a hloekileng. Tubing ea eona ea bohloeki-ea boemo ba polyurethane e kopana le maemo a FDA 'me e ka sebelisoa bakeng sa liphaephe tsa lino le lihlahisoa tsa lebese.
3. Lipalangoang tsa Likoloi le tsa Terene: E sebelisoa e le lithapo tsa mafura, lithapo tse pholisang, kapa lihokelo tse kopanyang lintho tse thellang; litšobotsi tsa eona tse bobebe li thusa ho fokotsa tšebeliso ea matla.
4. Marine Engineering: Hydrolysis{1}}resistant polyurethane tubing e loketse likhokahano tsa lisebelisoa tse ka tlas'a metsi likepeng le liforomong tse haufi le maoatle, tse thibelang ho bola ha metsi a leoatle.
IV. Mekhoa ea Ntlafatso le Liqholotso Ka ntlafatso ea theknoloji ea indasteri, polyurethane tubing e ntse e tsoela pele ho ea ts'ebetsong e phahameng le ho sebetsa ka bongata:
• Lintlafatso tsa Tikoloho: Ho ntlafala ho{{0}lisebelisoa tse entsoeng ka polyurethane e leng ho fokotsa khabone; ho ntlafatsa mekhoa ea ho tsosolosa ho fokotsa litšila.
• Integration e Bohlale: E kenya lisensara ho fihlella-khatello ea nako ea sebele le tlhahlobo ea mocheso, e sebelisoang lefapheng la tlhahiso e bohlale.
• Extreme Environment Adaptability: For ultra-high temperature (>120℃) kapa mecha ea litaba e nang le oxidizing haholo, theknoloji ea nanocomposite e ntlafatsa moeli oa mamello.
Leha ho le joalo, liphaephe tsa polyurethane le tsona li na le mefokolo. Ka mohlala, ho pepeseha ha nako e telele- UV ho ka 'na ha etsa hore bokaholimo bo thatafale, bo hloke tšireletso e sireletsang; mefuta e meng e fetotsoeng e ka eketsa litšenyehelo, e hlokang ho leka-lekana pakeng tsa ts'ebetso le moruo.
Joalo ka lekala la bohlokoa la lipeipi tsa sejoale-joale tsa indasteri, liphaephe tsa polyurethane, tse nang le khanyetso e ntle ea ho roala, ho hanyetsa kutu, le ho feto-fetoha ha maemo, e se e le khetho ea bohlokoa haholo libakeng tse ngata. Nakong e tlang, ka tsoelo-pele ea mahlale a thepa le theknoloji ea tlhahiso, sebaka sa ts'ebeliso ea liphaephe tsa polyurethane li tla hola le ho feta, athe boqapi bo tsoelang pele ba botsitso le bohlale bo tla fana ka tharollo e ntle bakeng sa ts'ebetso e nepahetseng ea litsamaiso tsa indasteri.
