I-Spunbond kunye ne-melt blown ziinkqubo ezimbini ezahlukeneyo zokwenziwa kwelaphu elingalukwanga, ezinomahluko omkhulu kwimathiriyeli ekrwada, iindlela zokusetyenzwa, ukusebenza kwemveliso, kunye nemimandla yesicelo.
Umgaqo wespunbond kunye nenyibilika evuthelweyo
I-Spunbond ibhekisa kwilaphu elingalukwanga elenziwe ngokukhupha imathiriyeli yepolymer kwimo etyhidiweyo, ukutshiza imathiriyeli etyhidiweyo kwi-rotor okanye emlonyeni, ukuyitsalela phantsi kwimo etyhidiweyo kwaye iqine ngokukhawuleza ukwenza imathiriyeli ye-fibrous, kwaye emva koko iyalukwa kwaye idibanise imicu nge-mesh okanye i-electrostatics spinning. Umgaqo kukukhupha i-polymer enyibilikisiweyo nge-extruder, kwaye emva koko uhambe kwiinkqubo ezininzi ezinje ngokupholisa, ukuzolula, kunye nokwelula okubhekiselele, ekugqibeleni kuqulunqwe ilaphu elingalukwanga.
I-Meltblown, kwelinye icala, yinkqubo yokukhupha imathiriyeli yepolymer ukusuka kwimeko enyibilikileyo ngokusebenzisa umlomo wesantya esiphezulu. Ngenxa yempembelelo kunye nokupholisa kwe-air-speed-speed-high, izinto zepolymer ziqina ngokukhawuleza zibe zixhobo ze-filamentous kwaye zidada emoyeni, eziye zicutshungulwe ngokwemvelo okanye zimanzi ukuze zenze inethiwekhi yefayibha entle yelaphu elingalukwanga. Umgaqo kukutshiza izixhobo zepolima ezinyibilikisiweyo ezinobushushu obuphezulu, zolule zibe yimicu ecolekileyo ngokuphuma komoya ngesantya esiphezulu, kwaye ziqine ngokukhawuleza zibe ziimveliso ezivuthiweyo emoyeni, zenza umaleko wemathiriyeli yelaphu elicolekileyo elingalukwanga.
Iimathiriyeli ekrwada ezahlukeneyo
Amalaphu angaphothiweyo angalukwanga ngokuqhelekileyo asebenzisa imicu yeekhemikhali ezifana ne-polypropylene (PP) okanye i-polyester (PET) njengezinto eziluhlaza, ngelixa amalaphu angeyiyo anyibilikayo anyibilikayo asebenzisa izinto zepolymer kwimeko etyhidiweyo, njengepolypropylene (PP) okanye i-polyacrylonitrile (PAN) .Iimfuno zezinto eziluhlaza ziyahluka. I-Spunbonding idinga i-PP ukuba ibe ne-MF ye-20-40g / min, ngelixa ukunyibilika kufuna i-400-1200g / min.
Uthelekiso phakathi kweentsinga ezinyibilikayo ezivuthelweyo kunye neentsinga zespunbond
A. Ubude beFayibha – i-spunbond njengefilament, inyibilika evuthelweyo njengosinga omfutshane
B. Amandla eFayibha: Amandla efayibha e-Spunbonded>Amandla efayibha anyibilikisiweyo
C. Ukulunga kweFayibha: Ifayibha enyibilikisiweyo ingcono kune-spunbond fiber
Iindlela ezahlukeneyo zokusetyenzwa
Ukucutshungulwa kwelaphu le-spunbond elingalukiweyo libandakanya ukunyibilika kwemicu yemichiza kumaqondo obushushu aphezulu, ukuzoba, kwaye emva koko kuqulunqwe isakhiwo sothungelwano lwefiber ngokupholisa kunye nokuzolula; Ilaphu elivuthelweyo elingalukwanga yinkqubo yokutshiza imathiriyeli enyibilikisiweyo yepolymer emoyeni ngokusebenzisa umbhobho onesantya esiphezulu, ukupholisa ngokukhawuleza nokuzolulela kwimicu ecolekileyo phantsi kwentshukumo yokuphuma komoya ngesantya esiphezulu, ekugqibeleni yenze umaleko wesakhiwo sothungelwano lwefiber eshinyeneyo.
Enye yeempawu zamalaphu angalukwanga anyibilikayo avuthelweyo kukuba ukucoleka kwefayibha kuncinci, ngokuqhelekileyo kungaphantsi kwe-10nm (iimicrometers), kwaye uninzi lweentsinga zinokucoleka kwe-1-4 rm.
Amandla ahlukeneyo kuwo wonke umgca ojikelezayo ukusuka kwi-nozzle evuthelweyo enyibilikayo ukuya kwisixhobo esifumanayo ayinakulungelelaniswa (ngenxa yokuguquguquka kwamandla obushushu obuphezulu kunye nesantya esiphezulu somoya, isantya kunye nobushushu bomoya opholileyo, njl.njl.), okukhokelela kwifiber engalinganiyo.
Ukufana kwedayamitha yefayibha kumnatha welaphu we-spunbond nonwoven ingcono kakhulu kuneentsinga zokutshiza, kuba kwinkqubo yespunbond, iimeko zenkqubo yokusonta zizinzile, kwaye iinguqu zokuyila kunye neemeko zokupholisa zincinci.
Ukuphuphuma kokujikeleza kuyahluka. I-Melt blown spinning yi-50-80 ℃ ngaphezulu kwe-spunbond spinning.
Isantya sokunwebeka semicu siyahluka. I-spinning meal 6000m / min, inyibilika ivuthelwe i-30Km / min.
Ukumkani wolula umgama wakhe, akaba nako ukuwubamba. I-Spunbound 2-4m, idibene 10-30cm.
Iimeko zokupholisa kunye nokutsala zihlukile. Iintsinga ze-Spinnbond zizotywa ngomoya obandayo/ongalunganga obandayo ku-16 ℃, ngelixa iifuse zivuthelwa ngomoya oshushu ophilileyo/ongalunganga kufutshane ne-200 ℃.
Ukusebenza kwemveliso eyahlukileyo
Amalaphu angaphothiweyo angalukwanga adla ngokuba namandla aphezulu okuqhekeka kunye nobude, kodwa ukuthungwa kunye nokufana kwe-fiber mesh kunokuba kubi, okuhlangabezana neemfuno zeemveliso ezisefashonini ezinjengeengxowa zokuthenga; Ilaphu elingalukwanga elinyibilikayo linokuphefumla kakuhle, ukuhluzwa, ukuxhathisa ukunxiba, kunye neempawu ezichasene ne-static, kodwa linokuba nesandla esibuthathaka kunye namandla, kwaye linokusetyenziswa ukwenza iimaski zonyango kunye nezinye iimveliso.
Iinkalo zesicelo ezahlukeneyo
Amalaphu angaphothiweyo angalukwanga asetyenziswa kakhulu kwezonyango, iimpahla, ikhaya, imizi-mveliso kunye namanye amasimi, anje ngeemaski, iigawuni zotyando, izigqubuthelo zesofa, iikhethini, njl. Ilaphu elingalukwanga elinyibilikayo lisetyenziswa ikakhulu kwezonyango, ezempilo, ekukhuselweni, ekukhuselweni kwendalo nakwezinye iindawo, ezinje ngeemaski eziphezulu, iimpahla ezikhuselayo, izihluzi, njl.
Ukuqukumbela
Ilaphu elingalukwanga elivuthelweyo kunye ne-spunbond elingalukwanga zizinto ezimbini ezahlukeneyo zelaphu elingalukwanga elineenkqubo ezahlukeneyo kunye neempawu. Ngokuphathelele isicelo kunye nokukhetha, kuyimfuneko ukuqwalasela ngokubanzi iimfuno zangempela kunye neemeko zokusetyenziswa, kwaye ukhethe eyona nto ifanelekileyo yelaphu engalukwanga.
