Lebitso la Sehlahiswa:polyester
Sebopeho sa limolek'hule tsa sehlahisoa:
Polyester ke sehlopha sa li-polymers tse nang le sehlopha se sebetsang sa ester karolong e 'ngoe le e' ngoe e pheta-phetoang ea ketane ea bona ea mantlha. E le thepa e khethehileng, hangata e bua ka mofuta o bitsoang polyethylene terephthalate (PET). Polyester e kenyelletsa lik'hemik'hale tse hlahang ka tlhaho, limela le likokoanyana, hammoho le li-synthetics tse kang polybutyrate. Li-polyester tsa tlhaho le tse seng kae tsa maiketsetso li khona ho senyeha, empa li-polyester tse ngata tsa maiketsetso ha li joalo. Li-polyester tsa maiketsetso li sebelisoa haholo liaparong. Ka linako tse ling likhoele tsa polyester li ohloa hammoho le likhoele tsa tlhaho ho hlahisa lesela le nang le thepa e tsoakiloeng. Metsoako ea k'hothone-polyester e ka ba matla, e sa sosobaneng le ho lla, 'me ea fokotsa ho honyela. Li-synthetic fibers tse sebelisang polyester li na le metsi a mangata, moea le ho hanyetsa tikoloho ha li bapisoa le likhoele tse tsoang ho limela. Ha li khone ho chesoa ke mollo 'me li ka qhibiliha ha li hotelitsoe. Li-polyester tsa crystalline tsa metsi ke tse ling tsa lipolima tsa pele tsa metsi tse sebelisoang indastering. Li sebelisetsoa thepa ea tsona ea mechine le ho hanyetsa mocheso. Litšobotsi tsena le tsona li bohlokoa ts'ebelisong ea tsona e le tiiso e abradable lienjineng tsa jete. Li-polyester tsa tlhaho li ka be li phethile karolo ea bohlokoa qalehong ea bophelo. Liketane tse telele tse fapaneng tsa polyester le meaho e se nang membrane li tsejoa hore li theha habonolo ka karabelo ea pitsa e le 'ngoe ntle le catalyst tlasa maemo a bonolo a prebiotic.
Masela a lohiloeng kapa a lohiloeng ka khoele ea polyester kapa khoele a sebelisoa haholo liaparong le thepa ea lapeng, ho tloha ho lihempe le borikhoe ho ea ho libaki le likatiba, lilakane tsa libethe, likobo, thepa ea ka tlung le meseme ea likhomphutha. Likhoele tsa liindasteri tsa polyester, likhoele le lithapo li sebelisoa ho matlafatsa thaere ea koloi, masela a mabanta a tsamaisang thepa, mabanta a tšireletso, masela a koahetsoeng le li-reinforcement tsa polasetiki tse monyang matla a phahameng. Fiber ea polyester e sebelisoa e le thepa e sireletsang le e sireletsang ka mesamong, litšelisong le liphaepheng tsa upholstery. Masela a polyester a hana matheba haholo—ha e le hantle, mofuta o le mong feela oa lidae o ka sebelisoang ho fetola ’mala oa lesela la polyester ke o tsejoang e le lidae tse qhalakaneng.[19] Li-polyester li boetse li sebelisetsoa ho etsa libotlolo, lifilimi, seile, liseile (Dacron), liketsoana, lipontšo tsa kristale ea metsi, li-holograms, li-filters, filimi ea dielectric bakeng sa li-capacitor, ho kenya filimi bakeng sa terata le litheipi tse sireletsang. Li-polyester li sebelisoa haholo e le qetello ea lihlahisoa tsa lehong tsa boleng bo holimo tse kang likatara, piano le li-interiors tsa koloi/yacht. Lintho tsa Thixotropic tsa li-polyester tse sebelisoang ke spray li etsa hore e be tse loketseng bakeng sa ho sebelisoa lifateng tse bulehileng, kaha li ka potlakela ho tlatsa lijo-thollo tsa lehong, tse nang le botenya ba filimi e phahameng ka ho fetisisa. E ka sebelisoa bakeng sa mese ea feshene, empa e ratoa haholo ka lebaka la bokhoni ba eona ba ho hanela ho sosobana le ho hlatsuoa habonolo. Ho tiea ha eona ho etsa hore e be khetho e tloaelehileng ea liaparo tsa bana. Hangata polyester e kopantsoe le likhoele tse ling tse kang k'hothone ho fumana tse ntle ka ho fetisisa lefatšeng ka bophara. Li-polyester tse phekotsoeng li ka etsoa lehlabathe 'me tsa belisoa ho fihlela qetellong, e khanyang, e tšoarella.
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)
