Sebopeho sa limolek'hule tsa sehlahisoa:
PMMA ke mokhoa o mong oa moruo ho feta polycarbonate (PC) ha matla a tsitsitseng, matla a flexural, ponaletso, polishability, le mamello ea UV e le tsa bohlokoa ho feta matla a amang, ho hanyetsa lik'hemik'hale, le ho hanyetsa mocheso.[6] Ho feta moo, PMMA ha e na li-subunits tse ka bang kotsi tsa bisphenol-A tse fumanehang ho polycarbonate mme ke khetho e ntle haholo bakeng sa ho itšeha ka laser. Hangata e ratoa ka lebaka la thepa ea eona e itekanetseng, ho sebetsana le ho sebetsa habonolo, le litšenyehelo tse tlaase. PMMA e sa fetoloang e sebetsa ka mokhoa o brittle ha e le tlas'a moroalo, haholo-holo tlas'a tšusumetso e matla, 'me e na le tšekamelo ea ho ingoaea ho feta likhalase tse tloaelehileng tsa inorganic, empa PMMA e fetotsoeng ka linako tse ling e khona ho finyella khanyetso e phahameng le tšusumetso.
Kaho ea maiketsetso ea Acrylic Meno a maiketsetso Botaki le botle bo sebelisa PMMA, ka mokhoa oa khoebo oa Technovit 7200 o sebelisoa haholo lefapheng la bongaka. E sebelisoa bakeng sa histology ea polasetiki, electron microscopy, hammoho le lisebelisoa tse ling tse ngata. PMMA e 'nile ea sebelisoa ho bopa lera le bosoeu bo bosoeu bo tenyetsehang 'me le fetohe ponahalo e bonaletsang ha le kolobile.[50] Acrylic e sebelisoa libetheng tsa ho fifala e le bokaholimo bo bonaletsang bo arohanyang motho ea lutseng ho li-bulbs tsa ho fifala ha matlalo a ntse a fifala. Mofuta oa acrylic o sebelisoang libetheng tsa ho fifala hangata o etsoa ho tloha mofuteng o khethehileng oa polymethyl methacrylate, motsoako o lumellang ho feta ha mahlaseli a ultraviolet. Lipampiri tsa PMMA li sebelisoa hangata indastering ea matšoao ho etsa litlhaku tse sehiloeng ka botenya ka tloaelo ho tloha ho 3 ho isa ho 25 millimeters (0.1 ho 1.0 in). Litlhaku tsena li ka sebelisoa li le mong ho emela lebitso la k'hamphani le/kapa letšoao, kapa e ka ba karolo ea litlhaku tsa kanale tse bonesitsoeng.

PMMA e ne e sebelisoa ho Laserdisc optical media.[51] (Li-CD le li-DVD li sebelisa li-acrylic le polycarbonate bakeng sa ho hanyetsa tšusumetso). E sebelisoa e le tataiso e khanyang bakeng sa mabone a morao-rao a TFT-LCDs. litšenyehelo li feta mamello ea eona e fokolang ea mocheso le ho fokotseha ho phahameng ho feta fiber ea khalase. PMMA, ka mokhoa o hloekisitsoeng, e sebelisoa e le matrix ka laser dae-doped organic solid-state gain media bakeng sa lilasers tsa dae tse tiileng tsa naha.[52] Lipatlisisong le indastering ea semiconductor, lithuso tsa PMMA e le khanyetso ts'ebetsong ea electron beam lithography.

Chemwin e ka fana ka mefuta e mengata ea li-hydrocarbon tse ngata le li-solvents tsa lik'hemik'hale bakeng sa bareki ba indasteri.Pele ho moo, ka kopo bala lintlha tse latelang mabapi le ho etsa khoebo le rona:
1. Tshireletso
Tšireletseho ke eona ntho e tlang pele bophelong ba rona. Ntle le ho fa bareki tlhahisoleseling mabapi le ts'ebeliso e sireletsehileng le e baballang tikoloho ea lihlahisoa tsa rona, re boetse re ikemiselitse ho netefatsa hore likotsi tsa polokeho ea basebetsi le borakonteraka li fokotsoa ho ba bonyane bo utloahalang le bo ka khonehang. Ka hona, re hloka hore moreki a etse bonnete ba hore litekanyetso tse nepahetseng tsa ho laolla le ho boloka polokeho li fihlelleha pele ho tlisoa ha rona (ka kopo sheba sehlomathiso sa HSSE ho latela maemo le maemo a kakaretso a thekiso a ka tlase). Litsebi tsa rona tsa HSSE li ka fana ka tataiso mabapi le litekanyetso tsena.
2. Mokhoa oa ho fana
Bareki ba ka odara le ho fana ka lihlahisoa ho tsoa ho chemwin, kapa ba ka fumana lihlahisoa ho tsoa femeng ea rona ea tlhahiso. Mekhoa e teng ea lipalangoang e kenyelletsa lipalangoang tsa literaka, terene kapa mefuta e mengata (maemo a arohaneng a sebetsa).
Tabeng ea litlhoko tsa bareki, re ka hlakisa litlhoko tsa likepe kapa litanka mme ra sebelisa litekanyetso tse khethehileng tsa polokeho / tlhahlobo le litlhoko.
3. Palo e fokolang ea taelo
Haeba u reka lihlahisoa sebakeng sa rona sa marang-rang, palo e tlase ea odara ke lithane tse 30.
4.Tefo
Mokhoa o tloaelehileng oa ho lefa ke ho fokotsa ka kotloloho matsatsing a 30 ho tsoa ho invoice.
5. Litokomane tsa thomello
Litokomane tse latelang li fanoe ka thomello ka 'ngoe:
· Bill of Lading, CMR Waybill kapa tokomane e 'ngoe e amehang ea lipalangoang
· Setifikeiti sa Tlhahlobo kapa Tumellano (haeba ho hlokahala)
· Litokomane tse amanang le HSSE tumellanong le melaoana
· Litokomane tsa meetlo ho latela melaoana (haeba ho hlokahala)
