Amamaskiyizindwangu ezingalukiwe, eziyizindwangu ezingalukiwe ngokungafani nezindwangu zendwangu, futhi zakhiwe ngemicu eqondisa noma engahleliwe.
Amamaski ezokwelapha ngokuvamile ayizakhiwo ezinezingqimba eziningi, ezivame ukubizwa ngokuthi izakhiwo ze-SMS (izingqimba ezimbili ze-S kanye ne-1 M). Njengamanje, inani eliphakeme kakhulu lezingqimba eShayina lingu-5, okungukuthi ama-SMMMS (izingqimba ezimbili ze-S kanye nezingqimba ezintathu ze-M).
Kuyini i-SMS?
Lapha, i-S imele ungqimba lwe-Spunbond. Ububanzi befayibha bukhulu kakhulu, cishe ama-microns angu-20 (m). Umsebenzi oyinhloko wezendlalelo ezimbili ze-S Spunbond ukusekela isakhiwo sendwangu esingelukiwe, esingenawo umthelela omkhulu esivimbelweni. Ingxenye ebaluleke kakhulu yemaski ungqimba lwesithiyo noma ungqimba lwe-Meltblown M (ungqimba lwe-Meltblown). Ububanzi besendlalelo sesifutho esincibilikisiwe buncane kakhulu, cishe ama-microns amabili (M), ngakho-ke kuyingxenye eyodwa kweziyishumi kuphela yobubanzi besendlalelo se-spunbonding, edlala indima ebalulekile ekuvimbeleni amagciwane nokungena kwegazi.
Amamaski ezokwelapha ajwayelekile avame ukusebenzisa indwangu yokufutha encibilikayo enesisindo esingamagremu angu-20, amamaski enkomishi ye-N95 asebenzisa indwangu yokufutha encibilikayo enesisindo esingamagremu angu-40 noma ngaphezulu.
Ngokwezibalo ze-China Industrial Textile Industry Association, ekupheleni kuka-2018, kunemigqa yokukhiqiza ye-spunbonded yasekhaya engu-1,477, engaphezu kuka-65 kunonyaka odlule, kanye nokwenyuka konyaka nonyaka okungu-4.6%, phakathi kwalokho, umugqa wokukhiqiza we-PP spunbonded non-wovens ukhushulwe ngo-3.38%, umugqa wokukhiqiza we-SMS composite cishe ngo-13%, kanye nomugqa wokukhiqiza we-PET spunbonded non-wovens ngo-9.32%. Inani lezinkampani ezinomkhiqizo waminyaka yonke odlula amathani angu-50,000 nalo lenyukile kusukela ngo-2017. Amabhizinisi e-spunbonded asheshisa intuthuko yawo ukuze afinyelele esikalini, ekuqineni nasekufinyeleleni okuphezulu ukuze ahlangabezane nesidingo semakethe sokuthuthukiswa komkhiqizo kanye nokuthuthukiswa kobuchwepheshe.
Kusukela ngo-2018, amabhizinisi amaningi asekhaya athuthukise imikhiqizo yawo ngendlela elula, encane futhi esebenza kahle, futhi athole imiphumela emihle. Inqubo ye-SSMMS spunbonded/molten shotcreting composite esebenza ngesivinini esiphezulu ingama-600m/min noma ngaphezulu; Cishe amagremu ayi-10 ngemitha yesikwele imikhiqizo yekhwalithi eqinile nethambile iyaqhubeka nokuvela.
Ivelaphi indwangu engalukiwe ye-SMS?
Izindwangu ezingalukiwe ze-SMSZenziwe kakhulu nge-polypropylene PP (ezinezakhiwo zemvelo ze-bacteriostatic kanye ne-hydrophobicity), futhi ububanzi bezintambo bungafinyelela kuma-microns angu-0.5-10. Lezi zintambo ezicolekile kakhulu ezine-capillarity eyingqayizivele zandisa inani kanye nendawo engaphezulu yezintambo endaweni ngayinye, okwenza izindwangu ezifafazwe ngokuncibilika zibe nezakhiwo ezinhle zokuhlunga umoya, okwenza zibe yimpahla yemaski enhle kakhulu.
Njengamanje, kunezinqubo ezintathu eziyinhloko zokukhiqiza imikhiqizo ye-SMS (indwangu engalukiwe ye-SMS): "inqubo yesinyathelo esisodwa", "inqubo yesinyathelo ezimbili" kanye "nenqubo yesinyathelo esisodwa nesigamu".
Izici zesinyathelo esisodwa ukusetshenziswa kwengxenye yezinto zokusetshenziswa zale nqubo, kusetshenziswa ubuchwepheshe obubili obuhlanganisiwe, obuncibilikisiwe, obuqondile bokuphotha izinto zokusetshenziswa ngemuva kokuncibilika emanetheni, inqobo nje uma kulungiselelwa inqubo ehlukene yobunjiniyela bezinhlelo zokuphotha, futhi kungenza imikhiqizo ibe nesakhiwo esihlukile, indwangu ngayinye ehlanganisiwe engqimbeni, ivame ukuba nokuhlanganiswa kwe-rolling mill eshisayo ibe yindwangu. "Indlela yesinyathelo esisodwa" ibonakala ngokuphotha ngqo kuphotha, isimo sohlelo ngalunye lokuphotha singalungiswa ngokuzimela, inqubo yokukhiqiza yokulawula okuqinile, izimo zempilo ezinhle, isivinini esikhulu, ingalungisa isilinganiso sengqimba ngayinye ye-fiber net, ingakhiqiza imikhiqizo yohlobo lwe-SMS yemininingwane ehlukahlukene, ubuchwepheshe obujwayelekile namuhla.
Inqubo enezinyathelo ezimbili: Uma usebenzisa inqubo enezinyathelo ezimbili ukukhiqiza imikhiqizo ye-SMS, imikhiqizo eqediwe yendwangu ephothiwe kanye nendwangu efafazwe ngokuncibilika iyavuleka ngokulandelana okuthile, bese ihlanganiswa ngokulandelana, bese ihlanganiswa nomshini wokugaya oshisayo, bese ihlanganiswa ibe imikhiqizo ye-SMS. Indlela enezinyathelo ezimbili ibonakala ngemishini elula kanye nezindleko eziphansi. Eqinisweni, inqubo "yezinyathelo ezimbili" ubuchwepheshe obuhlanganisiwe be-lamination obusetshenziswa kabanzi, kodwa futhi bungaba yinhlanganisela yezinye izinto, nezinye izinto ezahlukene, kanye nezindlela ezahlukene, njenge-ultrasonic, i-hot melt adhesive, izendlalelo ezintathu zezinto ndawonye.
Indlela yesinyathelo esisodwa nengxenye: ngendlela yesinyathelo ezimbili, kungenzeka futhi ukufaka umkhiqizo wendwangu yokufutha encibilikisiwe ngenethi yefayibha yesendlalelo yokufutha encibilikisiwe ekhiqizwe ensimini, ngaleyo ndlela kutholakale inqubo ehlanganisiwe ebizwa ngokuthi "indlela yesinyathelo esisodwa nengxenye". Indwangu ene-spunbonded isetshenziswa njengengqimba engezansi kanye nengqimba engaphezulu ngamadivayisi amabili okuvula, kanti inethi yefayibha yokufutha encibilikisiwe yesendlalelo esiphakathi iphothwa ngqo inethi ngohlelo lokufutha oluncibilikisiwe, ibekwe engqimbeni engezansi yendwangu ene-spunbonded, bese imbozwa ngengqimba engenhla yendwangu ene-spunbonded, kungcono ukusebenzisa umshini oshisayo ohlanganiswe nemikhiqizo ye-SMS.
