I-polypropylene engalukiwe vs i-polyester

Izindwangu ezingalukiwe azizona izindwangu ezilukiwe, kodwa zakhiwe ngamalungiselelo e-fiber oriented noma okungahleliwe, ngakho-ke zibizwa nangokuthi izindwangu ezingalukiwe. Ngenxa yezinto zokusetshenziswa ezihlukene kanye nezinqubo zokukhiqiza, izindwangu ezingezona ezilukiwe zingahlukaniswa zibe izinhlobo eziningi, njengeizindwangu ze-polyester ezingezona ezilukiwe, izindwangu ezingalukiwe ze-polypropylene, njll.

Amakhasimende avame ukubuza ngomehluko phakathi kwendwangu engalukiwe ye-polyester, indwangu engalukiwe ye-polypropylene, i-polypropylene fiber, ne-polyester lapho ebonisana nemikhiqizo yendwangu engalukiwe. Ngezansi kunohlu lokwehluka kwabo.

Indwangu engalukiwe ye-PET

Indwangu engalukiwe ye-PET spunbond filament iwuhlobo lwendwangu engalukiwe exosha amanzi, futhi ukusebenza kwayo kokuxosha amanzi kuyahlukahluka kuye ngesisindo sendwangu. Uma isisindo sikhulu futhi sikhulu, kuba ngcono ukusebenza kokuxosha amanzi. Uma kunamaconsi amanzi ebusweni bendwangu engalukiwe, amaconsi amanzi azoshelela ngokuqondile.

Indwangu engalukiwe ye-polyester imelana namazinga okushisa aphezulu. Ngenxa yokuncibilika kwe-polyester ezungeze u-260 ° C, ingakwazi ukugcina ukuqina kobukhulu bangaphandle bezindwangu ezingalukiwe ezindaweni ezidinga ukumelana nezinga lokushisa. Isetshenziswe kabanzi ekushicileleni ukudluliswa kokushisa, ukuhlunga uwoyela wokudlulisa, nezinye izinto eziyinhlanganisela ezidinga ukumelana nokushisa okuphezulu.

Indwangu engalukiwe ye-PET spunbondiwuhlobo lwendwangu engalukiwe eyi-filament yesibili kuphela kunendwangu engalukiwe ye-nylon spunbond. Amandla ayo amahle kakhulu, ukungena komoya okuhle, ukumelana nokuqina, ukumelana nezinyembezi kanye nezakhiwo zokulwa nokuguga sekusetshenziswe abantu abaningi emikhakheni ehlukahlukene.

Indwangu engalukiwe ye-PET spunbond nayo inendawo engokoqobo ekhetheke kakhulu: ukumelana nemisebe ye-gamma. Okusho ukuthi, uma isetshenziswa emikhiqizweni yezokwelapha, imisebe ye-gamma ingasetshenziswa ngokuqondile ekubulaleni amagciwane ngaphandle kokulimaza izakhiwo zayo ezingokomzimba nokuzinza kwe-dimensional, okuyindawo ebonakalayo izindwangu ezingalukiwe ze-polypropylene (PP) ezingenayo.

Indwangu engalukiwe ye-polypropylene

Indwangu engalukiwe ephothiwe isho umcu oqhubekayo owakhiwe ngokukhipha kanye nokwelulwa kwama-polymers, abekwe kuwebhu. Iwebhu ibe isizibophezela, iboshelwa ngokushisa, iboshelwe ngamakhemikhali noma iqiniswe ngomshini ukuze iguqule iwebhu ibe yindwangu engalukiwe. Isetshenziselwa imikhiqizo yokuhlanzeka elahlwayo, njengamanabukeni okugeza, izigqoko zokuhlinza, izigqoko, imaski, okokulala, izindwangu zamanabukeni, njll. Izingubo zabesifazane zokuhlanzeka seziphenduke imikhiqizo yansuku zonke yezingane ezilahlwayo, ama-diapers avamile.

I-polypropylene engalukiwe vs i-polyester

I-PP iyi-polypropylene impahla eluhlaza, okuyi-polypropylene fiber, okungokwendwangu encane engalukiwe; I-PET iwumkhiqizo omusha we-polyester, okuyi-polyester fiber, engenazo izithasiselo kuyo yonke inqubo yokukhiqiza. Kungumkhiqizo omuhle kakhulu ohambisana nemvelo futhi ungowendwangu ewugqinsi engalukiwe.

Umehluko phakathi kwe-polypropylene ne-polyester fibers

1, Umgomo wokukhiqiza

Izimiso zokukhiqiza ze-polypropylene ne-polyester fibers zihlukile. I-Polypropylene ilungiswa ngokushisisa ama-propylene monomers ekushiseni okuphezulu futhi iwangeze ku-catalyst ye-polymerization, kuyilapho imicu ye-polyester icutshungulwa ibe yizinto ze-fiber ngokungeza ama-cellulose etherification agents kanye nezinyibilikisi ku-polyester resin.

2. Izici zesakhiwo

1. Mayelana nezakhiwo ezibonakalayo:

I-Polypropylene inesisindo esincane uma kuqhathaniswa futhi inamandla amakhulu e-fibre, kodwa ukumelana kwayo nokugqoka kanye nokumelana nezinga lokushisa eliphezulu kubi. Imicu ye-polyester inamandla amakhulu okudonsa kanye nokuqina, kanye nokumelana nokushisa namakhemikhali, okuholela empilweni ende yesevisi.

2. Ngokwezakhiwo zamakhemikhali:

I-Polypropylene inezinto zamakhemikhali ezizinzile, ayigqwali kalula ngama-asidi, ama-alkali, njll., futhi ayinazo izinto ezinobuthi neziyingozi. I-polyester fiber iqukethe isakhiwo sendandatho ye-benzene futhi inezinga elithile lokumelana nokugqwala.

3. Mayelana nobungane bemvelo:

I-Polypropylene iyimpahla ye-thermoplastic engaboli kalula futhi ingcolise imvelo. Imicu ye-polyester ingonakaliswa ama-microorganisms futhi ngeke ibangele ukungcoliswa kwemvelo.

Umehluko phakathi kwe-PP yendwangu engalukiwe futhiIndwangu engalukiwe ye-PET

1. Izinto zokusetshenziswa ze-PP ishibhile, kuyilapho izinto zokusetshenziswa ze-PET zibiza. Imfucuza ye-PP ingagaywa kabusha esithandweni, kuyilapho imfucuza ye-PET ingakwazi ukugaywa kabusha, ngakho izindleko ze-PP ziphansi kancane.

2. I-PP inokumelana nokushisa okuphezulu okungama-degree angama-200, kuyilapho i-PET inokumelana nezinga lokushisa okungama-degree angama-290. I-PET imelana kakhulu namazinga okushisa aphezulu kune-PP.

3. Ukuphrinta kwendwangu engalukiwe, umphumela wokudlulisa ukushisa, ububanzi obufanayo be-PP buncipha kakhulu, i-PET incipha kancane, inomphumela ongcono, i-PET yonga kakhulu futhi imosha kancane.

4. Amandla okuqina, ukungezwani, amandla okuthwala umthwalo, nesisindo esifanayo, i-PET inamandla amakhulu, ingcindezi, namandla okuthwala umthwalo kune-PP. Amagremu angu-65 we-PET alingana namagremu angu-80 we-PP ngokuya ngengcindezi, ukushuba, namandla okuthwala umthwalo.

5. Ngokombono wemvelo, i-PP ixutshwe nemfucuza ye-PP egaywe kabusha, futhi wonke ama-PET chips masha sha. I-PET inobungani bemvelo futhi ihlanzekile kune-PP.
