Yintoni ilaphu elivuthelweyo?

Amalaphu angalukwanga abandakanya i-polyester, i-polypropylene, inayiloni, i-spandex, i-acrylic, njl. ngokusekelwe kwindlela eyakhiwe ngayo; Izithako ezahlukeneyo ziya kuba nezitayile ezahlukeneyo ngokupheleleyo zamalaphu angalukwanga. Zininzi iinkqubo zemveliso zokwenza amalaphu angalukwanga, kwaye ilaphu elingalukwanga elivuthelweyo yinkqubo yokunyibilika. Yenye yeenkqubo zokuvelisa ilaphu elingalukwanga kwaye yenye yeendlela ezithe ngqo zokubumba umnatha wepolymer. Yinkqubo yokukhupha i-polymer enyibilikayo ukusuka kwi-screw extruders ngokuvuthuza komoya ngesantya esiphezulu kunye nobushushu obuphezulu okanye ezinye iindlela zokubangela ukolula okugqithisileyo kokuhamba kwenyibilika kwaye zenze imicu emihle kakhulu, ethi iqokelele kumnatha wokwenza igubu okanye umnatha womnatha ukwenza umnatha wefayibha, Okokugqibela, ilaphu elinyibilikayo elivuthelweyo lefayibha engalukwanga yomelezwa ngokuzibophelela.

Ilaphu elivuthelweyo linyibilika lenziwe ikakhulu ngepolypropylene njengeyona nto iphambili ekrwada, kwaye idiameter yefiber inokufikelela kwi-1-5 microns. I-ultra-fine fibers enezakhiwo ezikhethekileyo ze-capillary, ezifana ne-multiple voids, i-fluffy structure, kunye nokumelana nokushwabana okulungileyo, ukwandisa inani kunye nommandla we-fiber kwindawo nganye yeyunithi, ngaloo ndlela yenza ilaphu elinyibilikayo elivuthelweyo libe nokucoca okulungileyo, ukukhusela, ukugquma, kunye neempawu zokufunxa ioli. Ingasetyenziswa kumasimi anje ngezixhobo zokucoca umoya kunye nolwelo, izixhobo zokuzihlukanisa, izinto zokufunxa, imathiriyeli yemaski, izinto zokugquma, izinto ezifunxa ioyile, kunye namalaphu osula.

Idayamitha yefayibha yomaleko ovuthelweyo enyibilikayo icoleke ngokugqithisileyo, ngokusisiseko ijikeleze i-2 microns (um), ngoko sisishumi esinye kuphela sobubanzi bomaleko we-spunbond. Okukhona inyibilika inyibilika umaleko, kokukhona inokuthintela ukungena kwamasuntswana amancinci. Umzekelo, imaski ye-KN95 ibhekisa kwisantya sokuhamba kwe-85L enokuthintela i-95% yamasuntswana amancinci (0.3um) phantsi kweemeko eziqhelekileyo. Oku kudlala indima ebalulekileyo ekuhluzeni ibhaktheriya kunye nokuthintela ukungena kwegazi, yiyo loo nto ibizwa ngokuba yintliziyo yemaski.

Ukuhamba kwenkqubo yemveli

Ukutya kwePolymer → Ukunyibilika okunyibilikayo → Ukwenziwa kweFayibha → Ukupholisa iFayibha → Ukwenziwa komnatha → Ukudibanisa (umnatha osisigxina) → ukusika komphetho kunye nokujiya → Ukugqiba isithuba okanye ukugqiba okukhethekileyo

Ukutya kwepolymer-Izixhobo zepolymer zePP zenziwa ngokubanzi zibe ziziqwenga ezincinci ezingqukuva okanye zegranular, zigalelwe kwiibhakethi okanye kwiihopper, kwaye zondliwe kwi-screw extruders.

I-Melt extrusion-Ekupheleni kokutya kwe-screw extruder, iitshiphusi zepolymer zixutywe kunye nezinto eziyimfuneko ezinje nge-stabilizers, ii-whitening agents, kunye ne-masterbatch yombala. Emva kokuvuselela ngokucokisekileyo kunye nokuxuba, bangena kwi-screw extruder kwaye batshiswe kwiqondo lokushisa eliphezulu ukuze benze ukunyibilika. Ekugqibeleni, inyibilika ifakwa kwi-spinneret ngesihluzo ngempompo yokulinganisa. Kwiinkqubo zokunyibilika, ii-extruders ngokubanzi zinciphisa ubunzima bemolekyuli yeepolymers ngokucheba kwazo kunye neziphumo zokuthotywa kobushushu.

Ukubunjwa kweFiber - I-melt ecocekileyo ecocekileyo idinga ukuhamba kwinkqubo yokusabalalisa kwaye emva koko ifakwe ngokulinganayo kwiqela ngalinye le-spinnerets, ukwenzela ukuba i-extrusion ye-extrusion ye-spinneret hole nganye ihambelana. Ipleyiti ye-spinneret ye-melt blown fibers yahlukile kwezinye iindlela zokujikeleza kuba imingxuma ye-spinneret kufuneka icwangciswe ngendlela echanekileyo, kunye nemingxuma ye-spout ye-speed-speed emoyeni kumacala omabini.

Ukupholisa i-Fiber - Ubungakanani obukhulu beqondo lokushisa lomoya ngexesha elifanayo kumacala omabini e-spinneret, lixutywe nokuhamba komoya oshushu oqulethe iifayili ze-ultrafine ukuze zizipholise phantsi, kwaye iifayili ze-ultrafine ezincibilikile zipholile kwaye ziqiniswe.

Ukubunjwa kwewebhu - Kwimveliso ye-melt blown fibre nonwoven fabrics, i-spinneret inokubekwa ngokuthe tye okanye ngokuthe nkqo. Ukuba ibekwe ngokuthe tye, emva koko iintsinga ze-ultrafine zitshizwa kwigubu lokuqokelelwa kwesetyhula ukwenza umnatha; Ukuba ibekwe ngokuthe nkqo, iintsinga ziya kuwela kumnatha othe tye oshukumayo kwaye ujike ube ngumnatha.

I-Adhesive (i-fixed mesh) - Ukuqiniswa kwe-self-adhesive ekhankanywe ngasentla yanele kwiinjongo ezithile zeendwangu ezincibilikayo ezinyibilikayo, ezifana nokufuna i-fiber mesh ukuba ibe nesakhiwo esithambileyo, ukugcinwa komoya okulungileyo okanye i-porosity, njl.
