Imikhiqizo Yendwangu Engalukiwe Ye-spunlace Enwebekayo

I. Inqubo Yendwangu Engalukiwe Ye-Spunlace Enwebekayo

Ingqikithi yendwangu e-elastic spunlace nonwoven itholakala ekufezeni ukusebenzisana "kwesakhiwo se-elasticity + spunlace" ngokukhetha izinto zokusetshenziswa kanye nokwenza ngcono inqubo. I-Changshu Yongdeli Spunlaced Nonwoven Fabrics Co., Ltd. iqinisekisa ukuqina okuzinzile kanye nokusebenza okuthembekile ngokulawula inqubo ngokucophelela. Inqubo ethile imi kanje:

Ukukhetha kanye nesilinganiso sezinto zokusetshenziswa eziyinhloko: Khetha imicu ye-polyester enwebekayo esezingeni eliphezulu. Imicu ye-polyester enwebekayo isebenzisa izinhlobo eziguquliwe ezinezinga eliphezulu lokubuyisa ukunwebeka (izinga lokubuyisa ukunwebeka ≥ 90%), elingabuya ngokushesha ngemva kokwelula;

Ukuvula nokuxuba: Sebenzisa imishini yokuvula nokuxuba ezinikele ukusabalalisa imicu ye-polyester enwebekayo. Le mishini isebenzisa umklamo ophansi wokucindezela ukuze igweme ukuthi imicu ye-elastic ilahlekelwe ukuqina kwayo ngenxa yokwelula ngokweqile; bese ingena emshinini wokuxuba we-biaxial, lapho amasethi amaningi amazinyo okuxuba efinyelela ukuxubana kwemicu ye-fiber efanayo ukuqinisekisa ukusatshalaliswa okufanayo kwemicu ye-elastic ku-mesh yendwangu, igweme ukuqina okungalingani ezindaweni ezithile, ibeke isisekelo sokwakheka kwewebhu okulandelayo kanye nokuma kwe-elastic.

Ukuhlanganisa nokwakheka kwewebhu (ukulawula ukuqondiswa kwe-elastic): Imicu ye-elastic ingena emshinini wokuxubha i-elastic fibre oqondile kakhulu. Umshini wokuxubha usebenzisa indwangu ekhethekile yenaliti (indwangu yenaliti yohlobo oluphansi lomonakalo) kanye nama-roller alungisekayo ukuze ahlukanise imicu ngenkathi elawula isiqondiso sokuhlelwa kwe-fiber (ikakhulukazi ukuqina kwe-longitudinal, kanye nokuqina kwe-lateral njengesengezo), ehambisana nezidingo ze-elastic zama-patches ezokwelapha (njengokuzivumelanisa ne-longitudinal kuya esiqondisweni sokunyakaza kwemilenze). Ngesikhathi senqubo yokuxubha, ukuqapha ngesikhathi sangempela ukuphambuka kobukhulu (kulawulwa ngaphakathi kwe-±2%) kuqinisekisa ukufana kwe-mesh yendwangu, kugwenywe ukujiya okungalingani okuthinta imiphumela elandelayo yokugquma kanye nokunamathela.

Ukuqinisa i-spunlace enwebekayo (inqubo eyinhloko): Lesi yisinyathelo esibalulekile sokunikeza umkhiqizo ukunwebeka, kusetshenziswa inqubo ethi "multiple progressive pressure spunlace":

I-spunlace yokuqala enomfutho ophansi (ingcindezi engu-5-8 MPa): Qala ulungise isakhiwo sendwangu ukuze uvimbele ukufuduka kwefayibha ngokweqile okubangelwa i-spunlace enomfutho ophezulu, uvikele isakhiwo esinwebekayo semicu ye-polyester enwebekayo;

I-spunlace eqondisa ngokucindezela okumaphakathi (ingcindezi engu-10-12 MPa): Ngekhanda le-spunlace elithambekele (nge-engeli engu-30°-45° kuya ku-mesh yendwangu) ukuze ifafazwe ngendlela eqondisa, okwenza imicu enwebekayo yakhe isakhiwo "esigoqekile - esigoqekile" eceleni kwendlela esethiwe (i-longitudinal), enikeza isikhala sokunwebeka nokubuya emuva;

I-spunlace ebumba umfutho ophezulu (ingcindezi engu-13-15 MPa): Sebenzisa ikhanda le-spunlace elinobukhulu obuphezulu ukuze uqinise ngokugcwele i-mesh yendwangu, uqinisekise ukunamathela okuqinile kwezintambo ezinwebekayo nezinye izintambo, ngenkathi ulawula ngokunembile ingcindezi ukuze ugweme ukuchotshozwa kwezintambo, ekugcineni kwakha isakhiwo esizinzile "sezintambo ezinwebekayo njengohlaka, ukunamathela kwe-spunlace njengokusekela", ngesilinganiso sokunwebeka eside esifinyelela ku-15%-30% kanye nesilinganiso sokunwebeka eceleni esifinyelela ku-8%-15%, okuhlangabezana nezidingo zama-patches ezokwelapha zokunamathela kokunyakaza kwemilenze.

Ukuphelelwa amanzi emzimbeni kanye nokuma komzimba okushisa okuphansi: Indwangu emanzi engalukiwe ethambile ngemva kokuqinisa i-spunlace ingena emshinini wokuphelelwa amanzi emzimbeni ongenayo i-vacuum (izinga lokuphelelwa amanzi emzimbeni elingu-70%-80%), bese ingena emshinini wokomisa umoya oshisayo okushisa okuphansi (izinga lokushisa elingu-70-90°C), enezinga lokushisa eliphansi kunezinga lokushisa lokomisa indwangu evamile engalukiwe ye-spunlace (100-120°C), okungagwema imicu ye-polyester ethambile ukulahlekelwa ukuqina ngenxa yokushisa okuphezulu. Ngesikhathi senqubo yokomisa, ukwakheka kwe-elastic kwenziwa ngesikhathi esisodwa. Ukucindezeleka kobuso bendwangu kulawulwa ama-roller okulawula izinga lokushisa ukuqinisekisa ukuthi umkhiqizo ugcina ukusebenza okuzinzile kokululama ngemva kokomisa, kanye nokuqukethwe komswakama kulawulwa ngaphakathi kuka-5%.

Ukwelashwa Kwangaphambi Komphezulu (ukufanisa ukugqoka): Ngezidingo ezilandelayo zokugqoka, imikhiqizo eyomisiwe ifakwa ekuphathweni kwangaphambi komphezulu: kusetshenziswa ubuchwepheshe bokwelashwa komphezulu we-plasma ukuthuthukisa amandla ongaphezulu (ukucindezelwa komphezulu ≥ 38 mN/m), ukuthuthukisa ukunamathela kuma-adhesive ashisayo ancibilikayo, ama-gel e-silicone, kanye nezinye izinto zokugqoka, kanye nokugwema izinkinga "zokususa iglu"; ​​ngesikhathi esifanayo, ukwelashwa kobushelelezi kwenziwa, ngokucindezela kancane umphezulu wendwangu ngama-roller acindezelwe athambile, ukuqinisekisa ukuthi umphezulu wendwangu uthambile (ukuphambuka kobuthambeka ≤ 0.1 mm/m), okunikeza isisekelo sokugqoka okufanayo.

Ukusika nokuhlolwa kwekhwalithi: Ngokwezidingo zobubanzi bokugoqa kwamakhasimende e-patch yokunamathela kwezokwelapha (ububanzi obuvamile obungu-0.5 - 2 m), imikhiqizo inqunywa ngemishini yokusika enembile kakhulu. Inqubo yokusika isebenzisa ukulawula kwe-tension closed-loop ukugwema ukuguquguquka kwe-elastic kwemikhiqizo ngenxa yokwelula; enkambisweni yokuhlola ikhwalithi, ngaphezu kokuhlolwa okuvamile kokubukeka namandla, "ukuhlolwa kokusebenza kwe-elastic" (ukuhlola izinga lokunwebeka kanye nezinga lokubuyisa i-elastic ngomshini wokuhlola othambekele) kanye "nokuhlolwa kokuhambisana kokumboza" (ukulingisa ukumboza ngemva kokuhlola ukunamathela kwesendlalelo sokunamathela) kuyangezwa ukuqinisekisa ukuthi inqwaba ngayinye yemikhiqizo ihlangabezana nezindinganiso ze-substrates ze-patch yokunamathela kwezokwelapha.

II. Izinhlobo zokumboza ezihambisanayo kanye nezinzuzo

Indwangu engalukiwe ye-spunlace enwebekayo ifanelekela izisekelo ezine zokumboza ezivame ukusetshenziswa zama-patches okunamathela kwezokwelapha.
