Ilaphu elingalukwanga / ilaphu elingalukwanga, njengemathiriyeli yelaphu engeyiyo eyemveli, yinto eyimfuneko nebalulekileyo kuluntu lwanamhlanje ngenxa yeempawu zalo ezizodwa kunye noluhlu olubanzi lwezicelo. Ikakhulu isebenzisa iindlela zomzimba okanye zekhemikhali ukudibanisa kunye nokuthunga iintsinga kunye, ukwenza ilaphu elinamandla athile kunye nokuthamba. Kukho iitekhnoloji ezahlukeneyo zemveliso zamalaphu angalukwanga, kwaye iinkqubo ezahlukeneyo zemveliso zinika amalaphu angalukiweyo iimpawu ezahlukeneyo ukuhlangabezana neemfuno ezahlukeneyo zesicelo.
Kumashishini amaninzi anjengobomi bemihla ngemihla, ishishini, kunye nokwakha, amalaphu angalukwanga angabonwa edlala indima yawo:
1. Kwinkalo yezempilo: iimaski, iingubo zokuhlinzwa, iimpahla zokukhusela, iingubo zonyango, i-napkins ye-sanitary, njl.
2. Izinto zokucoca: izihlungi zomoya, izihlungi zolwelo, izahluli zamanzi e-oyile, njl.
3. Izinto ze-Geotechnical: i-drainage network, i-membrane ye-anti-seepage, i-geotextile, njl.
4. Izixhobo zempahla: iingubo zokugqoka, i-lining, i-shoulder pads, njl.
5. Izinto zasekhaya: iibhedi, amalaphu etafile, iikhethini, njl.
6. Iimoto zangaphakathi: izihlalo zeemoto, iisilingi, iikhaphethi, njl.
7. Abanye: izinto zokupakisha, izahluli zebhetri, izinto zokufakelwa kwemveliso ye-elektroniki, njl.
Iinkqubo eziphambili zokuvelisa amalaphu angalukwanga ziquka oku kulandelayo:
1. Indlela ye-Meltblown: Indlela ye-Meltblown yindlela yokunyibilikisa imathiriyeli yefayibha ye-thermoplastic, ukuyitshiza ngesantya esiphezulu ukwenza imicu emihle, ize idityaniswe kunye yenze amalaphu angalukwanga ngexesha lenkqubo yokupholisa.
-Inkqubo yokuhamba: ipholima yokutya → inyibilika i-extrusion → ukwakheka kwefayibha → ukupholisa ifayibha → ukwakheka kwewebhu → ukuqinisa kwilaphu.
-Iimpawu: Imicu emihle, ukusebenza kakuhle kokucoca.
-Isicelo: Izinto zokucoca ezisebenzayo, ezinje ngeemaski kunye nezixhobo zokucoca zonyango.
2. Indlela ye-Spunbond: Indlela ye-Spunbond yinkqubo yokunyibilikisa izinto zefiber ze-thermoplastic, ukwenza iifiber eziqhubekayo ngokusebenzisa i-high-speed stretching, kwaye emva koko ipholise kwaye idibanise emoyeni ukuze yenze ilaphu elingalukwanga.
-Inkqubo yokuqukuqela: ipolymer extrusion → ukolula ukwenza imicu → ukwandlala kumnatha → ukudityaniswa (ukuzibophelela ngokwakho, ukudityaniswa kwe-thermal, ukudityaniswa kweekhemikhali, okanye ukomelezwa ngoomatshini). Ukuba i-roller ejikelezayo isetyenziselwa ukufaka uxinzelelo, iindawo zoxinzelelo ezishushu eziqhelekileyo (ii-pockmarks) zihlala zibonwa kumgangatho welaphu oxinyiweyo.
-Iimpawu: Iipropati ezilungileyo zoomatshini kunye nokuphefumla okugqwesileyo.
-Izicelo: izixhobo zonyango, iimpahla ezilahlayo, izinto zendlu, njl.
Kukho iiyantlukwano ezibalulekileyo kwi-microstructure phakathi kwamalaphu angalukwanga aveliswa yi-spunbond (ekhohlo) kunye neendlela ezinyibilikayo kwizinga elifanayo. Kwindlela ye-spunbond, iifiber kunye ne-fiber gaps zinkulu kunezo ziveliswa ngendlela ye-meltblown. Yiyo loo nto ibangela ukuba amalaphu angalukwanga anyibilikisiweyo anezikhewu ezincinci zefiber akhethelwe amalaphu angalukwanga ngaphakathi kweemaski.
