Yiziphi izinto zokusetshenziswa eziyinhloko zendwangu engalukiwe ephephethekayo

I-polypropylene ingenye yezinto eziyinhlokoAma-Raw materialngezindwangu ezingezona ezilukiwe, ezingafaka izindwangu ezingezona ezilukiwe ezinezakhiwo ezinhle kakhulu zomzimba.

Iyini indwangu engalukiwe

Indwangu engalukiwe iyisizukulwane esisha sempahla ehambisana nemvelo ehlanganisa imicu noma imicu emifushane eyimbudumbudu ngokusebenzisa amakhemikhali, umshini, noma izindlela eziyinhlanganisela yamakhemikhali, ngaphandle kokuhlela imicu ngendlela yendwangu.

Kungani usebenzisa i-polypropylene

I-Polypropylene ingenye yezinto ezisetshenziswa kakhulu zokusetshenziswa ekukhiqizeni izindwangu ezingalukiwe, ikakhulukazi ngenxa yezizathu ezilandelayo:

1. I-Polypropylene inokumelana okuhle kokugqoka kanye nokuqina, okungathuthukisa amandla nokuqina kwezindwangu ezingezona ezilukiwe;

2. I-Polypropylene kulula ukuyicubungula nokuma, okwenza inqubo yokukhiqiza izindwangu ezingalukiwe zibe lula;

3. I-Polypropylene iyancibilika emazingeni okushisa aphezulu futhi inganikeza ukubopha okuhle kwezindwangu ezingalukiwe.

Izici zezinto ezikhethekile ze-polypropylene zezindwangu ezincibilikayo

I-polypropylene ekhethekile ye-PP ye-PP iyi-polymer ye-thermoplastic yendawo yonke, enezici zamandla aphezulu, ukwahlukanisa okuhle, ukumuncwa kwamanzi aphansi, izinga lokushisa eliphezulu lokuguquguquka okushisayo, ukuminyana okuphansi, i-crystallinity ephezulu, nokugeleza okuhle kokuncibilika; Ngesikhathi esifanayo, inokumelana okuhle kwe-solvent, ukumelana nowoyela, i-asidi ebuthakathaka kanye nokumelana ne-alkali, futhi ayibizi futhi kulula ukuyithola, ngakho isetshenziswa kabanzi emkhakheni we-fiber.

Izidingo zenqubo yezinto ezikhethekile ze-polypropylene zendwangu encibilikisiwe

Ngenxa yemininingwane yobuchwepheshe obuncibilikisiwe, izinto zokusetshenziswa ze-PP ezisetshenziswa njengezinto ezikhethekile zokuncibilika kwezindwangu ezingalukiwe ezishisayo kumele zihlangabezane nalezi zidingo ezilandelayo:

(1) Inkomba ephezulu kakhulu yokuncibilika kufanele ibe nkulu kuno-400g/10min.

(2) Ukusatshalaliswa kwesisindo samangqamuzana amancane (MWD).

(3) Okuqukethwe komlotha ophansi, inkomba encibilikisiwe ephansi yezinto zokusetshenziswa ezincibilikisiwe, i-viscosity ephezulu yokuncibilika, edinga ukuthi i-extruder inikeze ingcindezi enkulu ukuze iwukhiphe kahle embobeni yembobo, edinga ukusetshenziswa kwamandla okukhulu futhi ifake imishini yokuncibilika ngaphansi kwengcindezi enkulu; Futhi ukuncibilika akukwazi ukwelulelwa ngokugcwele futhi kucwengisiswe ngemva kokukhishwa emgodini wokuphotha, okwenza kube nzima ukwenza imicu ye-ultrafine.

Ngakho-ke, izinto zokusetshenziswa ze-PP kuphela ezinenkomba ephezulu yokuncibilika ezingahlangabezana nezidingo zobuchwepheshe obuncibilikisiwe, zikhiqize izindwangu ezifanelekile ze-ultrafine fibre nonwoven, futhi zinciphise ukusetshenziswa kwamandla. Ukusatshalaliswa kwesisindo samangqamuzana okuhlobene kunomthelela omkhulu kuzakhiwo, ukusebenza kokucubungula, nokusebenziseka kwe-PP encibilikayo. Ukuze kukhiqizwe izindwangu ezingalukiwe ezincibilikisiwe, uma ukusatshalaliswa kwesisindo samangqamuzana kubanzi kakhulu futhi kunokuqukethwe okuphezulu kwesisindo esilinganiselwe samangqamuzana PP, ukuqhekeka kwengcindezi kwe-PP kuzoba kubi kakhulu.

Indima ye-polypropylene ezindwangu ezingezona ezilukiwe

1. Thuthukisa amandla nokuqina kwezindwangu ezingalukiwe

Ngenxa yokumelana nokugqokwa kwayo okuhle nokuqina, ukwengeza i-polypropylene kungathuthukisa amandla nokuqina kwezindwangu ezingalukiwe, kuzenze ziqine futhi zingagugi.

2. Thuthukisa ukusebenza kokuhlunga kwezindwangu ezingalukiwe

I-Polypropylene i-microporous material engakwazi ukuhlunga izinhlayiya ezincane ngokulawula usayizi we-pore ngesikhathi sokukhiqizwa kwezindwangu ezingalukiwe. Ngakho-ke, i-polypropylene ingabonisa ukusebenza okuhle kakhulu kokuhlunga ezindwangu ezingezona ezilukiwe.

3. Yenza indwangu engalukiwe ibe yisakhiwo esiqinile

I-Polypropylene iyancibilika emazingeni okushisa aphezulu futhi inikeza ukuhlangana okuhle kwezindwangu ezingalukiwe, yakha isakhiwo esiqinile phakathi kwemicu futhi yenza izindwangu ezingalukiwe zizinze futhi ziqine.

Isiphetho

Kafushane, i-polypropylene, njengenye yezinto ezisetshenziswa kakhulu zendwangu engalukiwe, inganikeza izindwangu ezingalukiwe izinto ezibonakalayo ezinhle kakhulu futhi idlala indima ebalulekile enqubweni yokukhiqiza izindwangu ezingalukiwe.
