Mukuona kweruzhinji, machira echinyakare anorukwa.Zita rejira risiri rakarukwa rinovhiringa, rinotoda kurukwa here?
Machira asina kurukwa anonziwo machira asina kurukwa, ari machira asingade kurukwa kana kurukwa.Harigadzirwe nekurukwa nekuruka shinda imwe neimwe, asi jira rinoumbwa nekubatanidza tambo dzakananga pamwechete nenzira dzemuviri.Panyaya yekugadzira machira, machira asiri akarukwa anoshandisa zvakananga machipisi epolymer, mapfupi faibha kana filaments kugadzira fiber kuburikidza nemhepo inoyerera kana mechanicha mambure, obva asimbisa nekuruka, kubaya kwetsono kana kupisa kupisa, uye pakupedzisira kugadzira jira risiri rakarukwa mushure mekupedza. Yemucheka.
Maitiro ekugadzira machira asiri akarukwa anogona kukamurwa kuita anotevera matanho:
1. Kubatanidza fiber;2. Fiber mumambure;3. Kugadzirisa fiber net;4. Ita kurapwa kwekupisa;5. Pakupedzisira, kupedzisa nekugadzirisa.
Zvinoenderana nezvikonzero zvemachira asiri akarukwa, anogona kuiswa se:
Spunlace machira asiri akarukwa: Majeti emvura akanyanya-kudzvanywa anopfapfaidzwa pane imwe kana akawanda akaturikidzana efiber webs kuti apinze mafiibha pamwe chete, nekudaro achisimbisa fiber webs.
Kupisa-kusunga jira risiri rakarukwa: kuwedzera fibrous kana powdery hot-melt bonding reinforcement material kune fiber web, kuitira kuti faibha dandemutande ripise nekunyungudutswa uye rozotonhodzwa kuti risimbise kuita jira.
Pulp air-laid non-woven fabric: inozivikanwawo sepepa-isina guruva, pepa rakaoma-kugadzira jira risiri rakarukwa.Inoshandisa tekinoroji yakamisikidzwa nemhepo kushandura huni dzehuni dzehuni kuita shinda imwe chete, uye mhepo-yakaiswa faibha dzinoshandiswa kubatanidza mafiibhi paketeni rewebhu wozosimbisa kuita jira.
Machira akanyorova akaiswa asiri akarukwa: Iyo faibha mbishi inoiswa mukati memvura inovhurwa kuita shinda imwe chete, uye akasiyana faibha mbishi zvinhu zvinosanganiswa kuita fibre suspension slurry, inotakurwa ichiendeswa kune webhu kugadzira michina, uye webhu inosanganiswa. kubatanidzwa mumucheka mumamiriro ekunyorova.
Spunbond jira risiri rakarukwa: Mushure mekunge polima yakwidibirwa uye yakatambanudzwa kuita filaments inoenderera, inoiswa mumambure, uye mambure efayibha anosungwa kana kusimbiswa nemichina kuti ive jira risiri rakarukwa.
Meltblown isiri-yakarukwa jira: Matanho ekugadzira ari polymer yekuisa-yakanyungudika extrusion-fiber kuumbwa-fiber kutonhora-net kuumbwa-kusimbisa mumucheka.
Jira rakabayiwa netsono risiri rakarukwa: Imhando yemucheka wakaoma-wakagadzika usina kurukwa, unoshandisa kubaya kwetsono kusimbisa dandemutande rakapfava kuita jira.
Machira akasonwa asiri akarukwa: Imhando yemucheka wakaomeswa usina kuruka, unoshandisa wap-yakarukwa loop chimiro kusimbisa fiber webhu, shinda yeshinda, isiri-yakarukwa zvinhu (senge pepa repurasitiki, nezvimwewo) kana musanganiswa wavo. kugadzira jira risiri rakarukwa .
Fiber mbishi zvinhu zvinodiwa kugadzira machira asiri akarukwa akafara kwazvo, senge donje, hemp, makushe, asbestos, girazi faibha, viscose faibha (rayon) uye synthetic fiber (inosanganisira nylon, polyester, acrylic, polyvinyl chloride, vinylon) Mira. )Asi mazuvano, machira asina kurukwa haachanyanyogadzirwa neshinda dzedonje, uye mamwe mafiibhi akaita serayon atora nzvimbo yawo.
Mucheka usina kurukwa zvakare rudzi rutsva rwezvinhu zvakatipoteredza, zvine hunhu hwekunyorova, kufema, elastic, huremu hwakareruka, husingabatike, huri nyore kuparara, husina chepfu uye husingatsamwisi, hune ruvara rwakapfuma. mutengo wakaderera, unogona kudzokororwa, nezvimwewo, saka iyo ndima yekushandisa Yakakura kwazvo.
Pakati pezvishandiso zvemaindasitiri, machira asiri akarukwa ane hunhu hwekusefa kwakanyanya, insulation, kupisa kupisa, acid resistance, alkali resistance, uye kubvarura kuramba.Iwo anonyanya kushandiswa kugadzira sefa midhiya, kuvharisa inzwi, kuvharwa kwemagetsi, kurongedza, denga uye abrasive zvinhu, nezvimwe chigadzirwa.Muindasitiri yezvinodiwa zvezuva nezuva, inogona kushandiswa sezvipfeko zvekupfeka, maketeni, madziro ekushongedza zvinhu, manapukeni, mabhegi ekufambisa, nezvimwewo Muzvigadzirwa zvekurapa uye zvehutano, zvinogona kushandiswa mukugadzira majasi ekuvhiya, majasi evarwere, masks, mabhandi ehutsanana, nezvimwewo.
