Ilaphu elingalukwanga/ilaphu elingalukwanga, njengezinto zelaphu ezingezizo ezemveli, zizinto ezibalulekileyo nezibalulekileyo kuluntu lwanamhlanje ngenxa yeempawu zalo ezizodwa kunye noluhlu olubanzi lwezicelo. Ngokuyintloko isebenzisa iindlela zomzimba okanye zeekhemikhali ukudibanisa nokudibanisa imicu kunye, yenze ilaphu elinamandla athile kunye nokuthamba. Kukho iindlela ezahlukeneyo zemveliso yamalaphu angalukwanga, kwaye iinkqubo ezahlukeneyo zemveliso zinika amalaphu angalukwanga iimpawu ezahlukeneyo ukuhlangabezana neemfuno ezahlukeneyo zesicelo.
Kwimizi-mveliso emininzi efana nobomi bemihla ngemihla, ishishini, kunye nokwakha, amalaphu angalukwanga angabonakala edlala indima yawo:
1. Kwicandelo lezempilo: iimaski, iilokhwe zotyando, impahla yokuzikhusela, iibhanti zonyango, iinapkin zococeko, njl.njl.
2. Izinto zokucoca: izihluzi zomoya, izihluzi zolwelo, izahluli zamanzi eoyile, njl.
3. Izixhobo ze-Geotechnical: inethiwekhi yokukhupha amanzi, i-membrane engangenisi amanzi, i-geotextile, njl.
4. Izixhobo zempahla: ilayini yempahla, ilayini, iiphedi zamagxa, njl.
5. Izinto zasekhaya: izinto zokulala, amalaphu etafile, amakhethini, njl.
6. Ingaphakathi leemoto: izihlalo zeemoto, iisilingi, iikhaphethi, njl.njl.
7. Ezinye: izinto zokupakisha, izahluli zebhetri, izixhobo zokukhusela imveliso nge-elektroniki, njl.
Iinkqubo eziphambili zemveliso yamalaphu angalukwanga ziquka oku kulandelayo:
1. Indlela yeMeltblown: Indlela yeMeltblown yindlela yokunyibilikisa izinto zefayibha yethermoplastic, uzitshize ngesantya esiphezulu ukuze zenze imicu emincinci, uze uzidibanise ukuze zenze amalaphu angalukwanga ngexesha lenkqubo yokupholisa.
-Ukuhamba kwenkqubo: ukondla nge-polymer → ukunyibilika kwe-extrusion → ukwakheka kwefayibha → ukupholisa ifayibha → ukwakheka kwewebhu → ukuqinisa ilaphu.
-Iimpawu: Iifayibha ezintle, ukusebenza kakuhle kokuhluza.
-Ukusetyenziswa: Izixhobo zokucoca ezisebenzayo, ezifana neemaski kunye nezixhobo zokucoca zonyango.
2. Indlela ye-Spunbond: Indlela ye-Spunbond yinkqubo yokunyibilikisa izinto zefayibha ye-thermoplastic, zenze iifayibha eziqhubekayo ngokuzolula ngesantya esiphezulu, uze uzipholise uze uzibophe emoyeni ukuze zenze ilaphu elingalukwanga.
-Ukuhamba kwenkqubo: i-polymer extrusion → ukolula ukwenza ii-filaments → ukubeka kwi-mesh → ukubophelela (ukuzibophelela ngokwakho, ukubophelela kobushushu, ukubophelela kweekhemikhali, okanye ukuqiniswa koomatshini). Ukuba kusetyenziswa i-roller ejikelezayo ukufaka uxinzelelo, amanqaku aqhelekileyo okucinezela ashushu (ii-pockmarks) ahlala ebonakala kumphezulu welaphu elicinezelweyo.
-Iimpawu: Iipropati ezilungileyo zoomatshini kunye nokuphefumla okugqwesileyo.
-Izicelo: izinto zonyango, impahla elahlwayo, izinto zasekhaya, njl.
Kukho umahluko omkhulu kwisakhiwo esincinci phakathi kwamalaphu angalukwanga aveliswe yi-spunbond (ekhohlo) kunye neendlela ze-meltblown ngesikali esifanayo. Kwindlela ye-spunbond, iifayibha kunye nezikhewu zefayibha zikhulu kunezo zenziwe yi-meltblown method. Kungoko ke kukhethwe amalaphu angalukwanga e-meltblown anezikhewu zefayibha ezincinci kumalaphu angalukwanga ngaphakathi kwiimaski.
