Zojambula za polyester(polyethylene terephthalate) ndi polymerized kuchokera ku refined terephthalic acid (PTA) ndi ethylene glycol.Maonekedwe ndi mpunga granular, ndipo pali mitundu yambiri (zonse zowala, theka, kuwala kwakukulu, cationic, kutha uku).
M'mawu amsika a tchipisi ta poliyesitala, nthawi zambiri mumawona mawu akuti "kuwala kwakukulu", "kutheratu" ndi "kuwala", omwe amanenedwa pano chifukwa cha titanium dioxide (TiO2) mu tchipisi ta polyester, ndikuwonjezera titanium dioxide (TiO2) mu sungunula ndi kuchepetsa kuwala kwa CHIKWANGWANI."Kuwala kwakukulu" (Yizheng mankhwala CHIKWANGWANI amatchedwanso "wapamwamba kuwala") zili titaniyamu woipa mu tchipisi poliyesitala ndi ziro;Zomwe zili mu titaniyamu woipa mu kagawo "zowala" poliyesitala ndi za 0,1%;Zomwe zili mu titaniyamu woipa mu "semi-bull" polyester chip ndi (0.32±0.03)%;Zomwe zili mu titanium dioxide mu "full extinction" polyester chip ndi 2.4% mpaka 2.5%.
Chifukwa chakukula kwachuma chapadziko lonse lapansi komanso kutukuka kwa moyo wa anthu, makampani opanga nsalu ndi zovala apita patsogolo mwachangu.Chip chosawoneka bwino cha polyester chakhala chikugwiritsidwa ntchito kwambiri chifukwa cha utoto wake wabwino kwambiri, mphamvu yayikulu komanso zinthu zabwino kwambiri zopangira, ndipo gawo logwiritsira ntchito lidzakulitsidwa tsiku ndi tsiku, ndikukhala zida zazikulu zopangira nsalu, filimu ya polyester mafakitale, ndi magawo ena.
Malinga ndi ntchito kagawo akhoza kugawidwa mu kagawo CHIKWANGWANI kalasi poliyesitala, kagawo botolo kalasi poliyesitala ndi filimu kalasi poliyesitala kagawo magawo atatu.
Tchipisi ta poliyesitala wa ulusi umagwiritsidwa ntchito popanga ulusi wa poliyesitala ndi ulusi wa poliyesitala, zomwe ndi zida zopangira ulusi ndi zinthu zina zokhudzana ndi mabizinesi a polyester CHIKWANGWANI.Tchipisi ta poliyesitala botolo amagawidwa m'magulu awiri a copolymerization ndi homopolization, omwe amatha kugawidwa m'mabotolo amadzi amchere, mabotolo akumwa mowa wa carbonated, mbiya zina zazakudya ndi zida zonyamula malinga ndi ntchito zosiyanasiyana.Chiyambireni filimu ya polyester m'zaka za m'ma 1950, chifukwa cha makina ake abwino kwambiri, kukana kwa mankhwala ndi kukhazikika kwa mawonekedwe, monga filimu yotchinga magetsi yapangidwa mofulumira ndikugwiritsidwa ntchito kwambiri.Ndi chitukuko cha mafakitale apanyumba, kugwiritsa ntchito filimu yokhuthala ya polyester kwakula kwambiri.M'zaka zaposachedwa, filimu ya poliyesitala yakhala ikugwiritsidwa ntchito kwambiri pakuyika zida, zosindikizira, zomangira, zida zamaofesi, zida zamaginito ndi zida zojambulira ndi zinthu zina za anthu wamba komanso minda yamakono komanso yapamwamba kwambiri.
Pakali pano, opanga lalikulu poliyesitala ndi sitepe kupanga, PTA ndi MEG polymerization salinso kupanga magawo, koma sanatchule wapakatikati kugwirizana mwachindunji kubala chokhazikika CHIKWANGWANI ndi ulusi.The theka-kutha mu kagawo nkhani 60%, koma kagawo kupota alibe msika, palibe mpikisano, ndipo msika ndi poyera.Kupanga madzi amchere ndi mabotolo ena akumwa ndi magawo, kupanga kwamakono kwakhala kochuluka, khalidwe la opanga silili yunifolomu.Toni imodzi ya polyester imatha kupanga mabotolo opitilira 33,000.Kuphatikiza apo, mapepala obwezerezedwanso, ndiko kuti, mabotolo apulasitiki otayidwa amasinthidwanso kuti apange ulusi wambiri, mtengo wotsika, mtengo wotsika, ndikuyeretsa chilengedwe.Koma kuzembetsa ndizovuta kwambiri, ndikudandaula kuti tsogolo lomwe latchulidwa lisokoneza dongosolo la msika.
