2. Likarolo tse ka hare: haholo-holo li kenyelletsa ho lula ha endoscope, li-wiper brackets le li-valve tsa tsamaiso ea taolo;

3. Likarolo tsa motlakase oa likoloi: li-coil tse sothehileng tsa li-tubes le li-connectors tse sa tšoaneng tsa motlakase, joalo-joalo.

c.Lisebelisoa tsa mochini: sekoaelo sa lebanta la sehatisi sa video, sekoaelo sa komporo ea elektroniki, sekoaelo sa lebone la mercury, sekoaelo sa tšepe ea motlakase, likarolo tsa mochini oa ho baka le likere tse ngata, lik'hamera, likonopo, li-casing tsa elektroniki, likarolo tsa khamera ( e hanyetsanang le mocheso, litlhoko tsa ho thibela mollo)

Tlamahano

Ho ea ka litlhoko tse fapaneng, o ka khetha li-adhesive tse latelang:

1. G-955: Karolo e le 'ngoe ea mocheso oa kamore e phekola sekhomaretsi se bonolo sa elastic shockproof, se hanyetsanang le mocheso o phahameng le o tlaase, empa lebelo la ho kopanya le lieha, hangata sekhomaretsi se nka letsatsi le 1 kapa matsatsi a' maloa ho phekola.

2. KD-833 sekhomaretsi sa hang-hang se ka kopanya polasetiki ea PS ka potlako ka metsotsoana e seng mekae kapa metsotsoana e mashome, empa sekhomaretsi sa sekhomaretsi se thata ebile se brittle, 'me ha se hanyetsane le ho qoelisoa ka metsi a chesang ka holimo ho likhato tse 60.

3. QN-505, sekhomaretsi sa likarolo tse peli, lera le bonolo la sekhomaretsi, se loketseng PS sebaka se seholo sa ho kopanya kapa ho kopanya.Empa ho hanyetsa mocheso o phahameng ho fokola.

4. QN-906: Sekhomaretsi sa likarolo tse peli, ho hanyetsa mocheso o phahameng.

5. G-988: Mocheso oa mocheso oa kamore e le 'ngoe oa vulcanizate.Kamora ho folisoa, ke elastomer e nang le sekhomaretsi se sa keneleng metsi hantle, se khomarelang ho ts'oha, ho hanyetsa mocheso o phahameng le o tlase.Haeba botenya bo le 1-2mm, bo tla fola ka lihora tse 5-6 mme bo na le matla a itseng.Ho nka bonyane lihora tse 24 ho fola ka botlalo.Karolo e le 'ngoe, ha ho hlokahale hore e kopane, e sebelise feela ka mor'a extruding' me e tlohele e eme ntle le ho futhumatsa.

6. KD-5600: Sekhomaretsi se phekolang sa UV, se tlamahanyang lipampitšana tse pepeneneng tsa PS le lipoleiti, li ke ke tsa fihlella phello ea mohlala, li hloka ho phekoloa ke leseli la ultraviolet.Phello e ntle ka mor'a ho khomarela.Empa ho hanyetsa mocheso o phahameng ho fokola.

Ts'ebetso ea lintho tse bonahalang

Motlakase o motle haholo (haholo-holo maqhubu a phahameng), o se nang 'mala ebile o bonaletsa, o fetisa leseli la bobeli feela ho plexiglass, coloration, ho hanyetsa metsi, botsitso ba lik'hemik'hale, matla a tloaelehileng, empa a brittle, ho bonolo ho baka khatello ea maikutlo, le ho se mamelle Litlhapi tsa tlhaho tse kang benzene. le peterole.E loketse ho etsa likarolo tse hlakileng tsa insulating, likarolo tse khabisitsoeng, lisebelisoa tsa lik'hemik'hale, lisebelisoa tsa optical le likarolo tse ling.

Ho etsa tshebetso

- Thepa ea amorphous, ho kenngoa ha mongobo o tlaase, ha ho hlokahale hore e omisitsoe ka ho feletseng, 'me ha ho bonolo ho senya, empa coefficient ea ho atolosa mocheso o moholo,' me ho bonolo ho hlahisa khatello ea kelello ka hare.E na le mokelikeli o motle mme e ka bōptjoa ka mochini oa ente ea screw kapa plunger.

⒉Ho eletsoa ho sebelisa mocheso o phahameng oa thepa, mocheso o phahameng oa hlobo, le khatello e tlase ea ente.Ho lelefatsa nako ea ente ho molemo ho fokotsa khatello ea kelello ka hare le ho thibela ho fokotseha le ho senyeha.

⒊Ho ka sebelisoa mefuta e fapaneng ea liheke, 'me liheke li kopantsoe le likarolo tsa polasetiki tsa arc ho qoba tšenyo ea likarolo tsa polasetiki ha heke e tlosoa.The angle demolding e kholo 'me ejection e tšoana.Botenya ba lerako la likarolo tsa polasetiki bo tšoana, ka ho khetheha ntle le ho kenya, joalo ka Ho kenya tse ling ho lokela ho behoa pele.

tshebediso

PS e sebelisoa haholo indastering ea optical ka lebaka la phetiso ea eona e ntle ea leseli.E ka sebelisoa ho etsa likhalase tsa optical le lisebelisoa tsa optical, hammoho le mebala e hlakileng kapa e khanyang, e kang li-lampshades, lisebelisoa tsa mabone, joalo-joalo PS e ka boela ea hlahisa likarolo tse ngata tsa motlakase le lisebelisoa tse sebetsang sebakeng se phahameng sa maqhubu.Kaha polasetiki ea PS ke ntho e thata ho e kenya ka holim'a metsi, hoa hlokahala ho sebelisa sekhomaretsi sa setsebi sa PS ho ikopanya le indasteri.

Ho sebelisa PS feela joalo ka sehlahisoa ho na le brittleness e phahameng.Ho kenyelletsa lintho tse ling tse nyane ho PS, joalo ka butadiene, ho ka fokotsa bofokoli haholo le ho ntlafatsa ho tiea ha tšusumetso.Plastiki ena e bitsoa PS e hanyetsanang le tšusumetso, 'me thepa ea eona ea mochine e ntlafala haholo.Likarolo tse ngata tsa mochini le likarolo tse nang le ts'ebetso e ntle haholo li entsoe ka polasetiki.
