Ingxowa engalukwanga imathiriyeli ekrwada

Imathiriyeli ekrwada yeengxowa ezingalukwanga

Iingxowa ezingalukwanga zenziwe ngelaphu elingalukwanga njengemathiriyeli ekrwada. Ilaphu elingalukwanga sisizukulwana esitsha sezinto ezihambelana nokusingqongileyo ezinobungqina bokufuma, obuphefumlayo, obubhetyebhetye, obukhaphukhaphu, obungatshiyo, obulula ukubola, obungenatyhefu nabungacaphukiyo, butyebile ngombala, buphantsi ngexabiso, kwaye bunokuphinda busetyenziswe. Esi sixhobo sinokubola ngokwemvelo emva kokubekwa ngaphandle kweentsuku ezingama-90, kwaye inobomi benkonzo obufikelela kwiminyaka emi-5 xa ibekwe ngaphakathi. Xa itshisiwe, ayinayo ityhefu, ayinavumba, kwaye ayinazinto ezishiyekileyo, ngoko ayingcolisi indalo. Yaziwa kumazwe ngamazwe njengemveliso ehambelana nokusingqongileyo yokukhusela i-ecology yoMhlaba.

Kukho izinto ezimbini eziphambili zeengxowa ezingalukwanga, enye i-polypropylene (PP), kwaye enye yi-polyethylene terephthalate (PET). Zombini ezi zixhobo luhlobo lwelaphu elingalukwanga, elenziwe yimicu ngokusebenzisa i-thermal bonding okanye ukuqiniswa komatshini, ngamandla aphezulu kunye nokusebenza kakuhle kokungena kwamanzi.

Ipolypropylene (PP): Le yinto eqhelekileyoimathiriyeli yelaphu engalukiweyongokumelana nokukhanya okulungileyo, ukuxhathisa ukubola, kunye namandla okuqina. Ngenxa yobume be-asymmetric kunye nokuguga okulula kunye nokwahlula, iingxowa ezingezona ezilukiweyo zinokuthi zenziwe nge-oxidized kwaye zibole kwiintsuku ezingama-90.

I-Polyethylene terephthalate (PET): ekwabizwa ngokuba yi-polyester, iingxowa ezingezona ezilukiweyo zesi sixhobo zihlala zihlala ixesha elide, kodwa xa kuthelekiswa nepolypropylene, iindleko zayo zokuvelisa ziphezulu.

Ukuhlelwa kweengxowa ezingalukwanga

1. Izinto eziphambili zeengxowa ezingalukwanga ziyilaphu elingalukwanga. Ilaphu elingalukwanga luhlobo lwelaphu elingalukwanga luhlobo olutsha lwemveliso yefiber ene-soft, ephefumlayo, kunye nesakhiwo esisicaba esenziwe ngokuthe ngqo kusetyenziswa iitshiphusi zepolymer eziphezulu, iintsinga ezimfutshane, okanye iintsinga ezinde ngeendlela ezahlukeneyo zokubumba umnatha wefayibha kunye neendlela zokuhlanganisa. Izinto eziluncedo: Iibhegi ezingalukwanga azibizi mali ininzi, zinobuhlobo nokusingqongileyo kwaye ziyasebenza, zisetyenziswa ngokubanzi, kwaye zineendawo ezibalaseleyo zentengiso. Ifanelekile kwimisebenzi eyahlukeneyo yeshishini kunye nemiboniso, sisipho esifanelekileyo sokukhuthaza intengiso kumashishini kunye namaziko.

2. Impahla ekrwada yelaphu elingalukwanga yi-polypropylene, ngelixa izinto ezisetyenziswa kwiingxowa zeplastiki yi-polyethylene. Nangona ezi zinto zimbini zinamagama afanayo, iikhemikhali zazo ziqelelene kakhulu. I-chemical molecular structure ye-polyethylene inozinzo olomeleleyo kwaye kunzima kakhulu ukuthotywa, ngoko iingxowa zeplastiki zithatha iminyaka engama-300 ukubola ngokupheleleyo; Nangona kunjalo, i-chemical structure ye-polypropylene ayinamandla, kwaye i-molecular chain chain iyakwazi ukuphuka ngokulula, enokuthi idibanise ngokufanelekileyo kwaye ingene kumjikelo wokusingqongileyo olandelayo kwifomu engeyona inetyhefu. Ingxowa engalukwanga ingaboliswa ngokupheleleyo kwiintsuku ezingama-90.

Ngokweenkqubo ezahlukeneyo zemveliso, inokwahlulwa ibe

1. Ukusonta: Yinkqubo yokutshiza ngoxinzelelo oluphezulu lwamanzi acwengileyo kwi-fiber mesh enye okanye ngaphezulu, okubangela ukuba iintsinga zihlangane kwaye zomeleze umnatha ukuya kwinqanaba elithile lamandla.

2. Ubushushu obutywiniweyo bengxowa yelaphu engalukiweyo: ibhekisa ekongezeni izinto ezincamathelayo ezincamathelayo ezinefibrous okanye ezilukiweyo ezishushu ezinyibilikayo kumnatha wefiber, emva koko ukufudumeza, ukunyibilika, kunye nokupholisa umnatha wefayibha ukuyiqinisa ibe ilaphu.

3. Pulp airflow net non-loven bag yelaphu: ikwabizwa ngokuba liphepha elingenathuli okanye ukwenza iphepha elomileyo elenziwe ngelaphu elingalukwanga. Isebenzisa itekhnoloji yomnatha wokuhamba komoya ukukhulula iplanga yefiberboard yomthi ibe yifayibha enye, emva koko isebenzise indlela yokuhamba komoya ukudibanisa imicu kumnatha womnatha, kwaye umnatha wefiber uyaqiniswa. 4. Ingxowa yelaphu emanzi engalukiweyo: Yinkqubo yokukhulula imathiriyeli ekrwada yefayibha ebekwe kwindawo yamanzi ibe yimisonto enye, kunye nokuxuba imathiriyeli ekrwada yefayibha ukwenza ifayibha suspension slurry. I-slurry yokunqunyanyiswa ihanjiswa kwindlela yokwenza iwebhu, kwaye iifibers ziqiniswa kwilaphu kwimeko emanzi.

5. Ilaphu elidityanisiweyo elingaphothiweyoibhegi: Yinkqubo apho i-polymer iye yakhutshelwa kwaye yolulelwa ukwenza i-filament eqhubekayo, ethi emva koko ibekwe kwiwebhu. Iwebhu ke iyazibophelela, ibotshwe ngokwe thermally, ibotshwe ngokwekhemikhali, okanye iqiniswe ngoomatshini ukuze iguquke ibe lilaphu elingalukwanga.

6. Inyibilika ibhegi yelaphu engalukiweyo evuthelweyo: Inkqubo yayo ibandakanya ukondla kwepolymer - melt extrusion - ifayibha ukwakheka - ukupholisa ifayibha - ukubunjwa kwemesh - ukuqinisa kwilaphu.

7. I-acupuncture: Ludidi lwelaphu elomileyo elingalukwanga elisebenzisa ukugqobhoza kwenaliti ukuqinisa umnatha wefiber ofukufuku kwilaphu.

8. Ukuthunga ukwaluka: Ludidi lwenkqubo eyomileyo yelaphu elingalukwanga elisebenzisa ulwakhiwo lwekhoyili oluniweyo ukuluka iintsinga, iileya zemisonto, izinto ezingalukwanga (ezinjengamashiti eplastiki, iifoyile zeplastiki ezicekethekileyo, njl. njl.) okanye amaqela abo.
