Zeziphi ezona mathiriyeli ziphambili zokunyibilika kwelaphu elingalukwanga elivuthelweyo

Ipolypropylene yenye yezona zinto ziphambiliiimpahla ezingekasilwakwiilaphu ezingalukwanga, ezinokunika amalaphu angalukwanga aneempawu ezintle zomzimba.

Yintoni ilaphu elingalukwanga

Ilaphu elingalukwanga sisizukulwana esitsha semathiriyeli ehambelana nokusingqongileyo edibanisa iintsinga okanye iintsinga zegranular ezimfutshane ngeendlela zekhemikhali, zoomatshini, okanye zemichiza, ngaphandle kokulungelelanisa iintsinga ngendlela yelaphu.

Kutheni usebenzisa i-polypropylene

I-Polypropylene yenye yezona zinto zixhaphakileyo kwimveliso yamalaphu angalukwanga, ikakhulu ngenxa yezi zizathu zilandelayo:

1. I-Polypropylene inokumelana nokunxiba kakuhle kunye nokuqina, okunokuphucula amandla kunye nokuqina kweendwangu ezingalukwanga;

2. I-Polypropylene kulula ukuyiqhuba kunye nokubunjwa, ukwenza inkqubo yokwenziwa kweendwangu ezingalukwanga zibe lula;

3. I-Polypropylene iyancibilika kumaqondo aphezulu kwaye inokubonelela ngokudibanisa okulungileyo kwiindwangu ezingalukwanga.

Iimpawu zezinto ezikhethekileyo zepolypropylene zamalaphu anyibilikayo

I-Melt ivuthelwe i-polypropylene ekhethekileyo ye-PP yipolymer ye-thermoplastic yendalo yonke, eneempawu zamandla aphezulu, ukugquma okulungileyo, ukufunxa kwamanzi aphantsi, ubushushu obuphezulu be-thermal deformation, ubuninzi obuphantsi, i-crystallinity ephezulu, kunye nokuhamba kakuhle kwe-nyibilika; Kwangaxeshanye, inokumelana ne-solvent elungileyo, ukumelana ne-oyile, i-asidi ebuthathaka kunye nokumelana ne-alkali, kwaye ayibizi kwaye kulula ukuyifumana, ngoko isetyenziswa kakhulu kwifayibha.

Iimfuno zenkqubo yezinto ezikhethekileyo zepolypropylene kwilaphu elinyibilikayo

Ngenxa yobuchwephesha betekhnoloji evuthelweyo, imathiriyeli yePP esetyenziswa njengezinto ezikhethekileyo zokunyibilika amalaphu angalukwanga aqhunyisweyo kufuneka ahlangabezane nezi mfuno zilandelayo:

(1) Isalathisi esinyibilikayo esiphezulu kakhulu kufuneka sibe sikhulu kune-400g / 10min.

(2) Ukusabalalisa ubunzima bemolekyuli encinci (MWD).

(3) Isiqulatho sothuthu oluphantsi, isalathiso esisezantsi sokunyibilika kwezinto ezinyibilikayo ezinyibilikayo, i-viscosity ephezulu yokunyibilika, efuna i-extruder inike uxinzelelo olukhulu ukuyikhupha ngokutyibilikayo kumngxuma wombhobho, ifuna ukusetyenziswa kwamandla amakhulu kunye nokubeka izixhobo ezinyibilikayo kuxinzelelo olukhulu; Kwaye i-melt ayinakolulwa ngokupheleleyo kwaye ihlanjululwe emva kokuba ikhutshwe kumngxuma wokujikeleza, okwenza kube nzima ukwenza imicu ye-ultrafine.

Ke ngoko, yimathiriyeli ekrwada yePP kuphela enesalathisi esinyibilikayo esinokuhlangabezana neemfuno zetekhnoloji enyibilikayo, ivelise amalaphu afanelekileyo e-ultrafine fiber nonwoven, kunye nokunciphisa ukusetyenziswa kwamandla. Ukuhanjiswa kobunzima bemolekyuli kunempembelelo enkulu kwiipropathi, ukusetyenzwa kwentsebenzo, kunye nokusetyenziswa kwePP enyibilikayo. Ukuvelisa amalaphu angeyolukiweyo anyibilikayo, ukuba ukuhanjiswa kobunzima bemolekyuli kubanzi kakhulu kwaye kukho umxholo ophezulu wobunzima bemolekyuli yePP, uxinzelelo lwePP luya kuba lubi kakhulu.

Indima yepolypropylene kwiilaphu ezingalukwanga

1. Ukuphucula amandla kunye nokuqina kweendwangu ezingalukwanga

Ngenxa yokumelana nokunxiba kakuhle kunye nokuqina, ukongeza i-polypropylene kunokuphucula amandla kunye nokuqina kwamalaphu angalukwanga, awenze aqine ngakumbi kwaye anganxibi.

2. Ukuphucula ukusebenza kohluzo lwamalaphu angalukwanga

I-Polypropylene yi-microporous material enokucoca amaqhekeza amancinci ngokulawula ubungakanani bayo be-pore ngexesha lokuveliswa kweendwangu ezingalukwanga. Ke ngoko, i-polypropylene inokubonisa ukusebenza kakuhle kokucoca kumalaphu angalukwanga.

3. Yenza ilaphu elingalukwanga libe lukhuni

I-Polypropylene inyibilika kumaqondo obushushu aphezulu kwaye ibonelela ngokuhlangana okuhle kwamalaphu angalukwanga, yenze ulwakhiwo oluqina phakathi kwemicu kwaye yenze amalaphu angalukwanga azinze kwaye omelele.

Ukuqukumbela

Ngamafutshane, i-polypropylene, njengenye yezixhobo eziphambili zelaphu elingalukwanga, inokunika amalaphu angalukwanga aneempawu ezibalaseleyo zomzimba kwaye idlala indima ebalulekileyo kwinkqubo yokwenziwa kwamalaphu angalukwanga.
