Indwangu engalukiwe/indwangu engalukiwe, njengendwangu engeyona eyendabuko, iyinto ebalulekile emphakathini wanamuhla ngenxa yezakhiwo zayo ezihlukile kanye nobubanzi bezicelo. Isebenzisa kakhulu izindlela zomzimba noma zamakhemikhali ukuhlanganisa nokuhlanganisa imicu ndawonye, yakha indwangu enamandla athile nobumnene. Kunezindlela ezahlukene zokukhiqiza zezindwangu ezingalukiwe, futhi izinqubo ezahlukene zokukhiqiza zinikeza izindwangu ezingalukiwe izici ezahlukene ukuze kuhlangatshezwane nezidingo ezahlukene zokusetshenziswa.
Ezimbonini eziningi ezifana nokuphila kwansuku zonke, imboni, kanye nokwakha, izindwangu ezingalukiwe zingabonakala zidlala indima yazo:
1. Emkhakheni wezempilo: imaski, izingubo zokuhlinzwa, izingubo zokuzivikela, izingubo zokwelashwa, ama-napkin ahlanzekile, njll.
2. Izinto zokuhlunga: izihlungi zomoya, izihlungi zoketshezi, izihlukanisi zamanzi namafutha, njll.
3. Izinto ze-Geotechnical: inethiwekhi yokukhipha amanzi, ulwelwesi olungangenisi amanzi, i-geotextile, njll.
4. Izesekeli zezingubo: ulwelwesi lwezingubo, ulwelwesi, amaphedi ehlombe, njll.
5. Izinto zasekhaya: izingubo zokulala, izindwangu zetafula, amakhethini, njll.
6. Ingaphakathi lezimoto: izihlalo zezimoto, ophahleni, amakhaphethi, njll.
7. Ezinye: izinto zokupakisha, izihlukanisi zebhethri, izinto zokuvikela umkhiqizo kagesi, njll.
Izinqubo eziyinhloko zokukhiqiza izindwangu ezingalukiwe zifaka okulandelayo:
1. Indlela ye-Meltblown: Indlela ye-Meltblown iyindlela yokuncibilikisa izinto ze-thermoplastic fiber, uzifafaze ngesivinini esikhulu ukuze zakhe imicu emincane, bese uzihlanganisa ndawonye ukuze zakhe izindwangu ezingalukiwe ngesikhathi senqubo yokupholisa.
-Ukugeleza kwenqubo: ukondla nge-polymer → ukuncibilikisa i-extrusion → ukwakheka kwefayibha → ukupholisa ifayibha → ukwakheka kwewebhu → ukuqinisa indwangu.
-Izici: Imicu emihle, ukusebenza kahle kokuhlunga.
-Ukusebenza: Izinto zokuhlunga ezisebenza kahle, njengezifihla-buso nezinto zokuhlunga zezokwelapha.
2. Indlela ye-Spunbond: Indlela ye-Spunbond inqubo yokuncibilikisa izinto ze-thermoplastic fiber, ukwakha imicu eqhubekayo ngokunwebeka ngesivinini esikhulu, bese kuba ukupholisa nokuyibopha emoyeni ukuze kwakheke indwangu engalukiwe.
-Ukugeleza kwenqubo: i-polymer extrusion → ukwelula ukwakha ama-filaments → ukubeka ku-mesh → ukubopha (ukuzibopha ngokwakho, ukubopha okushisa, ukubopha kwamakhemikhali, noma ukuqinisa ngomshini). Uma kusetshenziswa i-roller eyindilinga ukufaka ingcindezi, amaphuzu avamile okucindezela okushisa (ama-pockmark) avame ukubonakala ebusweni bendwangu ecindezelwe.
-Izici: Izakhiwo ezinhle zemishini kanye nokuphefumula okuhle kakhulu.
-Izicelo: izinto zokwelapha, izingubo ezilahlwayo, izinto zasekhaya, njll.
Kukhona umehluko omkhulu esakhiweni esincane phakathi kwezindwangu ezingalukiwe ezikhiqizwa yi-spunbond (kwesobunxele) kanye nezindlela ze-meltblown ngesilinganiso esifanayo. Ngendlela ye-spunbond, izikhala zemicu kanye ne-fiber zikhulu kunalezo ezikhiqizwa yindlela ye-meltblown. Yingakho futhi kukhethwa izindwangu ezingalukiwe ze-meltblown ezinezikhala ezincane ze-fiber zezindwangu ezingalukiwe ngaphakathi kwamaski.
