    IZIMPAHLA ZAMAKHEMIkhali

    I-Polyethylene terephthalate (PET) iyi-polymer eyi-semi crystalline enokumelana okuhle kakhulu kwamakhemikhali, ukuhamba okuncibilikayo nokujikeleza.I-polymer yakhiwe ngamayunithi aphindayo njengoba kukhonjisiwe kuMfanekiso 1. Iyunithi ngayinye enobude obuphathekayo obucishe bube ngu-1.09 nm kanye nesisindo samangqamuzana esingu-~200.Uma ikhiqizwa ekuphenduleni kwe-terephthalic acid ne-ethylene glycol, ifakwe kwesokunxele ngu-H- futhi kwesokudla ngu-OH.Ngakho-ke i-polymerization ihambisana nokukhiqizwa kwamanzi asuswa ngaphansi kwezinga lokushisa eliphakeme kanye ne-vacuum.Ngokunjalo ukuba khona kwamanzi esimweni esincibilikisiwe kuzosusa ubumbano ngokushesha kwesakhiwo ukuze ukoma okuphelele kwe-polymer ngaphambi kokuncibilika kokuphotha kwemicu kuyadingeka.

    Indandatho enephunga elimnandi ehambisana neketango elifushane le-aliphatic yenza i-polymer ibe i-molecule eqinile uma iqhathaniswa namanye ama-aliphatic polymers njenge-polyolefin noma i-polyamide.Ukuntuleka kokuhamba kwezigaba emaketangeni e-polymer kubangela ukuzinza okuphezulu kokushisa.I-polymer yezinga lendwangu izoba nenani elimaphakathi lamayunithi aphindayo ayi-100 nge-molecule ngayinye ukuze ubude obunwetshiwe bochungechunge lwe-polymer evamile bube ngu-100nm ngesisindo se-molecular cishe u-20,000.Amazinga aphezulu e-polymerization akhiqiza imicu yamandla aphezulu kodwa ukuncibilika kwe-viscosity nokuzinza kokuncibilika kuya kumanani amancane omswakama kubangela ukuwohloka kwe-hydrolytic.Isilinganiso sedigri ye-avareji ye-polymerization senziwa noma yi-viscosity encibilikisiwe (ngokulinganisa ukwehla kwengcindezi nge-orifice elinganisiwe) noma i-viscosity ye-polymer ehlanjululwe ku-solvent efanele.Lesi sakamuva isilinganiso sobude beketango le-polymer eyaziwa ngokuthi i-Intrinsic viscosity noma i-IV futhi inani le-polymer ye-fiber grade evamile ngu-0.6 dl/g ku-60/40 w/w ingxube ye-phenol ne-tetrachloroethane solvent.I-IV ku-solvent yakamuva ihlobene ne-Mv (I-Viscosity isilinganiso sesisindo semolekyuli) se-polymer ngesibalo sika-Mark Howink (Isibalo 1).

    I-Polyethylene terephthalate, evame ukubizwa ngayo yi-PET, iyilungu lomndeni we-polyester wama-polymers.Inhlanganisela yezakhiwo ezinjengokuqina nokuqina, ukuzinza kwe-dimensional, ukumelana namakhemikhali kanye ne-lightweight, kwenza i-PET ibe yinto eguquguqukayo esetshenziswa kabanzi ekusetshenzisweni okuningana okufana nemicu, amashidi. , amafilimu, nezitsha zeziphuzo.Isetshenziswa ezingxenyeni zikagesi ezihlanganisa izisekelo zokudlulisa kanye nezisekelo zamalambu, izindlu zokumpompa, amagiya, ama-sprockets, izingalo zesihlalo, ama-caster kanye nezingxenye zefenisha.
    Njengamanye ama-polyester, i-PET ikhiqizwa ezimbonini nge-esterification eqondile yama-dicarboxylic acid ane-diols.Izinqubo zokukhiqiza ezijwayelekile zisekelwe ku-polymerization ye-ethylene glycol (MEG) nge-purifiedterephthalic acid (PTA) noma i-dimethyl terephthalate (DMT) phambi kwe-catalyst yensimbi. .

    UTHENGA KANJANI KITHI

    I-Chemwin ingahlinzeka ngenqwaba yama-hydrocarbon amaningi nezincibilikisi zamakhemikhali kumakhasimende ezimboni.Ngaphambi kwalokho, sicela ufunde ulwazi olulandelayo oluyisisekelo mayelana nokwenza ibhizinisi nathi: 

    1. Ezokuphepha

    Ukuphepha kuyinto ehamba phambili yethu.Ngaphezu kokunikeza amakhasimende ulwazi mayelana nokusetshenziswa okuphephile nokunobungani kwemvelo kwemikhiqizo yethu, siphinde sizibophezele ekuqinisekiseni ukuthi ubungozi bokuphepha kwabasebenzi nosonkontileka buncishiswa bube buncane obunengqondo nobunokwenzeka.Ngakho-ke, sidinga ukuthi ikhasimende liqinisekise ukuthi izindinganiso ezifanele zokuphepha zokuthulula nokugcina impahla ziyahlangatshezwa ngaphambi kokulethwa kwethu (sicela ubheke isithasiselo se-HSSE emigomeni nemibandela yokuthengisa ngezansi).Ochwepheshe bethu be-HSSE banganikeza isiqondiso kulawa mazinga.

    2. Indlela yokulethwa

    Amakhasimende anga-oda futhi alethe imikhiqizo evela ku-chemwin, noma angathola imikhiqizo evela embonini yethu yokukhiqiza.Izindlela zokuthutha ezitholakalayo zifaka phakathi iloli, ujantshi noma ezokuthutha ezinezinhlobo eziningi (kuyasebenza izimo ezihlukene).

    Endabeni yezidingo zekhasimende, singacacisa izidingo zezikebhe noma amathangi futhi sisebenzise amazinga akhethekile okuphepha/wokubuyekeza kanye nezimfuneko.

    3. Inani elincane le-oda

    Uma uthenga imikhiqizo kuwebhusayithi yethu, inani elincane le-oda amathani angama-30.

    4.Inkokhelo

    Indlela yokukhokha ejwayelekile idonswa ngokuqondile zingakapheli izinsuku ezingu-30 ukusuka ku-invoyisi.

    5. Amadokhumenti okulethwa

    Amadokhumenti alandelayo anikezwa ngokudiliva ngakunye:

    · I-Bill of Lading, i-CMR Waybill noma enye incwadi yezokuthutha efanele

    · Isitifiketi Sokuhlaziya noma Ukuvumelana (uma sidingeka)

    · Imibhalo ehlobene ne-HSSE ngokuhambisana nemithethonqubo

    · Imibhalo yeCustoms ngokuhambisana nemithethonqubo (uma kudingeka)
