Amalaphu Angalukwanga: Enziwe Ngaphandle Komsonto Omnye

Intoni Is "Akukho okwalukiwe" ?

Ukuba ukhe wasebenzisa imaski yobuso, i-water wipe, okanye ibhegi yokuthenga, ukhe wayichukumisailaphu elingelolukiweyo. Kodwa nantsi inguqu: ayinayo i-warp, ayina-weft, ayinantambo, kwaye ayinaluki. Ilaphu lendabuko lifuna ukusontwa nokulukwa—amanyathelo amabini amakhulu. I-Nonwoven iyawadlula omabini. Iifayibha (okanye iplastiki enyibilikisiweyo) zifakwa ngqo kwiwebhu, emva koko zidityaniswe bubushushu, ukungqubana, okanye izincamathelisi zeekhemikhali. Ngowama-2022, iTshayina yavelisa iitoni ezizizigidi ezisi-8.29 zayo—ngaphezulu kwesithathu sehlabathi liphela. Lelona candelo likhula ngokukhawuleza kwimpahla yokulahlwa, kuba ayikhathazeki “ngempahla yokulahlwa” konke konke.

I-Meltblown: Isihluzi Esiphezulu

I-MeltblownIqala ngeepellets zepolypropylene, ezinyibilikiswayo kwaye zikhutshwe ngee-nozzles ezincinci. Ukuqhuma komoya oshushu ongama-200‑300°C kuyolula ukunyibilika kube zii-microfibers ezinobukhulu obuyi-1‑5 microns—ezinye zincinci njenge-0.5 microns. (Unwele lomntu lumalunga ne-70 microns.) Ezi fibres zincinci kakhulu zenza i-maze exineneyo, erhabaxa ebamba iibhaktheriya, amathontsi, kunye namasuntswana. Yiyo loo nto umaleko ophakathi wemaski yotyando kufuneka unyibilike. Ingxaki: isebenza kwi-1‑5 m/min kuphela, ivakala ibuthathaka, kwaye ixabisa i-$3,500‑5,500 ngetoni—ixabiso eliphindwe kabini ukuya kathathu kunezinye izinto ezingezizo ezolukiweyo. Ngoko awusoze uyibone yodwa; ihlala iliqhawe elifihlakeleyo elibekwe phakathi kwee-layers ezinamandla.

I-Spunbond: Ihashe Elisebenzayo

I-Spunbond ikwanyibilikisa i-polymer, kodwa ikhupha ii-filaments eziqhubekayo ezingama-15-35 microns ubukhulu—ziqinile kwaye ziqinile. Inwebeka emoyeni kwaye ibekwe kwibhanti ehambayo, i-web ibotshelelwa ngobushushu zii-roller ezishushu. Isiphumo: ilaphu eliqinileyo, elingakrazuliyo elihamba nge-50-500 m/min (ukuya kuthi ga kwi-1,000 m/min kwimigca yesantya esiphezulu)—ikhawuleza ngokuphindwe kalikhulu kune-meltblown. Eso santya sinciphisa sibiza ukuya kwi-$1,700-2,800 ngetoni. I-Spunbond yimpahla yakho yokutya, isigqubuthelo sezolimo, i-lining yefenitshala, kunye nomaleko wangaphandle weengubo zokuzikhusela. Ixabiso liphantsi kwaye liqinile, kodwa liqinile kwaye linjengeplastiki—ayiyo into ongathanda ukusula ubuso bakho ngayo.

I-SMS: Kungcono Ukuba Nobabini

Iimveliso zokwenyani azikhethi inkqubo enye kuphela. I-SMS-spunbond/meltblown/spunbond-yesiqhelo idibanisa ezona zilungileyo kuzo zombini. Iingubo zonyango zisebenzisa i-spunbond yangaphandle ukuvimba ulwelo, i-middle meltblown ukubamba amasuntswana, kunye ne-inner spunbond ukuze ikhululeke.imaski yotyandoiyafana: umaleko ongaphandle ugxotha ukutshiza, i-meltblown ibamba iintsholongwane, kwaye umaleko ongaphakathi ufunxa umswakama. Nee-wet wipes ezininzi zidibanisa umaleko othambileyo we-spunlace onesiseko esomeleleyo se-spunbond. Iinkqubo zodwa zinobuthathaka; ukuhlanganiswa okukrelekrele kunika ukusebenza ngaphandle kokuchitha imali.

Ayizizo Zonke Izinto Ezingalukwanga Ezidalwe Zilingana

Akukho okwalukiweKukho yonke indawo - iimaski, iiwipes, iibhegi, izihluzi, iigowns—kodwa uninzi lwabantu alukwazi ukwahlula i-meltblown kwi-spunbond. Ngoku uyazi: ufuna i-filtration? Ufuna i-meltblown. Ufuna amandla kunye nexabiso eliphantsi? I-Spunbond yimpendulo yakho. Kwaye ukuba ubona i-SMS, ujonge isandwich eyenziwe ngobuchule. Igama elifanayo "lelaphu", ukusebenza okwahlukileyo kakhulu—kunye nomsantsa weendleko ophindwe kahlanu. Ukuqonda ezi ndlela akuyi kukwenza ingcali yelaphu, kodwa kuya kukwenza ube ngumthengi okrelekrele.
