    IIPROPATI ZEKHEMICAL

    I-Polyethylene terephthalate (i-PET) yi-polymer e-semicrystalline ekwazi ukumelana neekhemikhali, ukunyibilika kunye nokujikeleza.I-polymer yenziwe ngeeyunithi eziphindaphindayo njengoko kubonisiwe kuMfanekiso 1. Iyunithi nganye enobude bomzimba obumalunga ne-1.09 nm kunye ne-molecular weight ~ 200.Xa iveliswa kwi-reaction ye-terephthalic acid kunye ne-ethylene glycol, ifakwe ngakwesobunxele ngu-H-kunye nekunene ngu-OH.I-Polymerization ke ngoko ihamba kunye nokuveliswa kwamanzi asuswe phantsi kobushushu obuphakamileyo kunye ne-vacuum.Ngokufanelekileyo ubukho bamanzi kwisimo esinyibilikisiweyo buya kuphelisa ngokukhawuleza ubume besakhiwo ukuze ukomiswe ngokucokisekileyo kwepolymer phambi kokunyibilika kokusonta kwemicu kuyimfuneko.

    Iringi enuka kamnandi edityaniswa nekhonkco elifutshane le-aliphatic yenza i-polymer ibe yimolekyuli eqinile xa ithelekiswa nezinye iipholima ze-aliphatic ezifana ne-polyolefin okanye i-polyamide.Ukunqongophala kokuhamba kwecandelo kumakhonkco e-polymer kubangela ukuzinza okuphezulu kwe-thermal.Ipolima yomgangatho we-textile iya kuba ne-avareji yenani le-100 leeyunithi eziphindayo kwimolekyuli nganye ukuze ubude obandisiweyo betsheyini yepolymer eqhelekileyo bube malunga ne-100nm kunye nobunzima bemolekyuli malunga nama-20,000.Amanqanaba aphezulu epolymerization avelisa imicu yamandla aphezulu kodwa ukunyibilika kwe-viscosity kunye nokuzinza kokunyibilika ukuya nakwizixa ezincinci zokufuma kubangela ukuthotywa kwe-hydrolytic.Umlinganiselo weqondo lomndilili we-polymerization wenziwa mhlawumbi nge-viscosity etyhidiweyo (ngokulinganisa ukuhla koxinzelelo nge-orifice elinganisiweyo) okanye i-viscosity ye-polymer diluted kwi-solvent efanelekileyo.Lo wokugqibela ngumlinganiselo we-polymer chain chain obizwa ngokuba yi-Intrinsic viscosity okanye i-IV kunye nexabiso le-polymer ye-fiber grade ye-0.6 dl / g kwi-60/40 w/w umxube we-phenol kunye ne-tetrachloroethane solvent.I-IV kwi-solvent yokugqibela inxulumene ne-Mv (i-Viscosity i-avareji ye-molecular weight) ye-polymer ngu-Mark Howink equation (Equation 1).

    I-Polyethylene terephthalate, edla ngokubizwa ngokuba yi-PET, lilungu lentsapho ye-polyester yeepolymers.Ukudityaniswa kweempawu ezifana nokuqina kunye nokuqina, ukuzinza kwe-dimensional, ukumelana neekhemikhali kunye nokukhanya okulula, kwenza i-PET ibe yinto eguquguqukayo esetyenziswa ngokubanzi kwizicelo ezininzi ezifana neefayili, amashidi. , iifilim, kunye nezikhongozeli zeziselo.Isetyenziswa kwiindawo zombane ezibandakanya iziseko zombane kunye neziseko zezibane, izindlu zokumpompa, iigiya, iisprockets, iingalo zesitulo, iicaster kunye nezinto zefenitshala.
    Njengezinye iipolyester, i-PET iveliswa kwimizi-mveliso nge-esterification ngokuthe ngqo ye-dicarboxylic acids ene-diols.Iinkqubo zokuvelisa eziqhelekileyo zisekelwe kwi-polymerization ye-ethylene glycol (MEG) kunye nokuba yi-purifiedterephthalic acid (PTA) okanye i-dimethyl terephthalate (DMT) phambi kwe-catalyst yensimbi. .

    INDLELA YOKUTHENGA KUTHI

    I-Chemwin inokubonelela ngoluhlu olubanzi lwee-hydrocarbons ezininzi kunye nezinyibilikisi zeekhemikhali kubathengi bamashishini.Ngaphambi koko, nceda ufunde olu lwazi lulandelayo olusisiseko malunga nokwenza ishishini nathi: 

    1. Ukhuseleko

    Ukhuseleko yeyona nto iphambili kuthi.Ukongeza ekunikeni abathengi ngolwazi malunga nokusetyenziswa ngokukhuselekileyo nokuhambelana nokusingqongileyo kweemveliso zethu, sikwazimisele ekuqinisekiseni ukuba imingcipheko yokhuseleko lwabasebenzi kunye neekontraka ziyathotywa ukuya kutsho kubuncinane obufanelekileyo nobunokwenzeka.Ngoko ke, sifuna ukuba umthengi aqinisekise ukuba imigangatho efanelekileyo yokukhutshwa kunye nokugcinwa kwemigangatho yokhuseleko idibene ngaphambi kokunikezelwa kwethu (nceda ubhekisele kwisihlomelo se-HSSE kwimimiselo jikelele kunye neemeko zokuthengisa ngezantsi).Iingcali zethu zeHSSE zinokubonelela ngesikhokelo kule migangatho.

    2. Indlela yokuhambisa

    Abathengi banokuodola kwaye bahambise iimveliso kwi-chemwin, okanye banokufumana iimveliso kwisityalo sethu sokuvelisa.Iindlela ezikhoyo zothutho ziquka iilori, uloliwe okanye uthutho lweendlela ezininzi (kuyasebenza iimeko ezahlukileyo).
