Indwangu engalukiwe/indwangu engalukiwe, njengempahla yendwangu engeyona eyendabuko, iyinto ebaluleke kakhulu futhi ebalulekile emphakathini wanamuhla ngenxa yezakhiwo zayo ezihlukile kanye nobubanzi bezicelo. Ikakhulukazi isebenzisa izindlela ezingokomzimba noma zamakhemikhali ukuze ibophe futhi ihlanganise imicu ndawonye, yakhe indwangu enamandla athile nokuthambile. Kunobuchwepheshe obuhlukahlukene bokukhiqiza bezindwangu ezingalukiwe, futhi izinqubo ezihlukene zokukhiqiza zinikeza izindwangu ezingalukiwe izici ezihlukene ukuze zihlangabezane nezidingo ezihlukahlukene zohlelo lokusebenza.
Ezimbonini eziningi ezifana nempilo yansuku zonke, izimboni, nezokwakha, izindwangu ezingalukiwe zingabonakala zidlala indima yazo:
1. Emkhakheni wezokunakekelwa kwempilo: imaski, izingubo zokuhlinza, izingubo zokuzivikela, izingubo zezokwelapha, ama-napkins, njll.
2. Izinto zokuhlunga: izihlungi zomoya, izihlungi eziwuketshezi, izihlukanisi zamanzi zamafutha, njll.
3. Izinto ze-Geotechnical: inethiwekhi yokukhipha amanzi, i-anti-seepage membrane, i-geotextile, njll.
4. Izesekeli zokugqoka: izingubo zokugqoka, i-lining, amahlombe ehlombe, njll.
5. Izinto zasendlini: okokulala, izindwangu zetafula, amakhethini, njll.
6. Ingaphakathi lezimoto: izihlalo zemoto, usilingi, okhaphethi, njll.
7. Abanye: izinto zokupakisha, izihlukanisi zebhethri, izinto zokufakelwa komkhiqizo we-elekthronikhi, njll.
Izinqubo eziyinhloko zokukhiqiza izindwangu ezingalukiwe zihlanganisa okulandelayo:
1. Indlela ye-Meltblown: Indlela ye-Meltblown iyindlela yokuncibilikisa izinto zefayibha ye-thermoplastic, ukuyifutha ngesivinini esikhulu ukuze kwakhe imicu emihle, bese ihlanganiswa ndawonye ukuze yenze izindwangu ezingalukiwe phakathi nenqubo yokupholisa.
-Ukugeleza kwenqubo: ukuphakelwa kwe-polymer → i-extrusion encibilikayo → ukwakheka kwefayibha → ukupholisa ifayibha → ukwakheka kwewebhu → ukuqinisa kube yindwangu.
-Izici: Imicu emihle, ukusebenza kahle kokuhlunga.
-Isicelo: Izinto zokuhlunga ezisebenzayo, njengamamaski nezinto zokuhlunga zezokwelapha.
2. Indlela ye-Spunbond: Indlela ye-Spunbond iyinqubo yokuncibilikisa izinto zefayibha ye-thermoplastic, ukwakha imicu eqhubekayo ngokusebenzisa ukunwetshwa kwesivinini esikhulu, bese kupholiswa futhi kuhlanganiswe emoyeni ukuze kwakhiwe indwangu engalukiwe.
-Ukugeleza kwenqubo: i-polymer extrusion → ukwelula ukuze kwakhe imicu → ukubeka kunenetha → ukubopha (ukuzibopha ngokwakho, ukubopha okushisayo, ukubopha amakhemikhali, noma ukuqinisa imishini). Uma i-roller eyindilinga isetshenziselwa ukufaka ingcindezi, amaphuzu okucindezela ajwayelekile ashisayo (ama-pockmark) avame ukubonakala endaweni yendwangu ecindezelwe.
-Izici: Izakhiwo ezinhle zemishini kanye nokuphefumula okuhle kakhulu.
-Izicelo: Izinsiza zokwelapha, izingubo ezilahlwayo, izinto zasendlini, njll.
Kunomehluko omkhulu ku-microstructure phakathi kwezindwangu ezingalukiwe ezikhiqizwe i-spunbond (kwesokunxele) nezindlela zokuncibilika esikalini esifanayo. Ngendlela ye-spunbond, imicu kanye nezikhala zefiber zinkulu kunalezo ezikhiqizwa indlela yokuncibilika. Kungakho futhi izindwangu ezingalukiwe ezincibilikisiwe ezinezikhala ezincane zefiber zikhethwa ezindwangu ezingalukiwe ngaphakathi kumaski.
