Ka tsoelo-pele e tsoelang pele ea theknoloji ea tlhahiso ea masela, likhoele tse ncha tse ngata li fetohile thepa e tala bakeng sa masela. Kajeno, ke tla u tsebisa haholo-holo theknoloji ea ho khetholla likhoele tsa polyester tse sebelisitsoeng hape.
Hoa utloisisoa hore nakong e fetileng, ka lebaka la khaello ea mekhoa ea tlhahlobo le ho hloleha ha mekhatlo ea liteko ho fana ka litlaleho tsa boleng, likhoebo li ne li sa khone ho thabela maano a naha a amehang, 'me ka nako e ts'oanang li bakile pherekano mabapi le ho ngoloa ha lihlahisoa tse ling tsa polyester.
Faeba ea polyester e sebelisoang hape (PET) ke eng?
Ke hore, thepa ea masela ea polyester (PET) polymer le polyester (PET) li sebelisoa hape 'me li sebetsoa hore e be fiber ea polyethylene terephthalate.
Ka mantsoe a tloaelehileng, faeba ya polyester e sebedisitsweng hape (eo ho tloha ka nako eo e tla bitswa polyester e sebedisitsweng hape) e bolela polyester e sebedisitsweng hape (jwalo ka di-flakes tsa botlolo, foam, silika e senyehileng, pulp ya ditshila, masela a senyehileng, jj.) e entsweng ka mekgwa ya ho sebedisetsa hape. Faeba ya Ester.
Molao-motheo oa ho Itsebahatsa
Ho latela phapang ea bohlokoa pakeng tsa ts'ebetso ea ho sebetsana le polyester e sebelisitsoeng hape le polyester e sa tsoakoang, e fellang ka litšobotsi tse fapaneng, sampole e sebetsoa ho latela maemo a boletsoeng 'me e lekoa ho chromatograph ea metsi e sebetsang hantle.

Ka keketseho ea tšebeliso ea polyester le temoso ea batho mabapi le tšireletso ea tikoloho, tlhokomelo e ntseng e eketseha e lebisoa ho sebelisoeng hape ha litšila tsa polyester. Tšebeliso ea litšila tsa polyester ho hlahisa fiber ea polyester e sebelisitsoeng hape e ka fokotsa litšenyehelo, ea fokotsa tšebeliso ea oli, le ho ntlafatsa melemo ea moruo, e leng ea bohlokoa haholo ntlafatsong e tsitsitseng ea indasteri ea fiber ea lik'hemik'hale.
Ka nako e ts'oanang, ka keketseho ea bongata ba polyester e sebelisitsoeng hape, taba ea ho nkeloa sebaka ha polyester e sebelisitsoeng hape le polyester e sa tsoakoang e hohetse tlhokomelo e eketsehileng ho tsoa indastering.
