Iti efakwe kwiingxowa ikhule ngokukhawuleza ngenxa yeenzuzo zayo "zobuninzi, ucoceko, ukulula, kunye nesantya", kwaye imakethi yeti efakwe kwiingxowa kwihlabathi liphela ibonisa umkhwa wokukhula ngokukhawuleza.
Njengezinto zokupakisha iingxowa zeti,iphepha lokucoca itiAkufuneki nje kuphela ukuba izithako ezisebenzayo zeti zikwazi ukungena ngokukhawuleza kwisuphu yeti ngexesha lenkqubo yokwenza ibhiya, kodwa zikwathintela nomgubo weti ebhegini ukuba ungangeni kwisuphu yeti. Emva kweminyaka yophuhliso, izinto zephepha lesihluzo seti ziye zatshintsha kancinci kancinci ukusuka kwi-gauze, iphepha lesihluzo, i-nylon, i-PET, i-PVC, i-PP kunye nezinye izinto ukuya kwi-corn fiber.
Ifayibha yombona, ekwaziwa ngokuba yifayibha ye-polylactic acid (PLA), ifumaneka kwizityalo ezivuselelekayo ezifana nombona, iitapile, kunye nomququ wezityalo. Iyakwazi ukuhambelana kakuhle ne-biodegradable, iipropati zokulwa ne-antibacterial, kunye nokuphefumla. Ayinakusetyenziswa kuphela ukwenza iingxowa zeti ezingalukwanga ezinokubola, kodwa ikwasetyenziswa kwintsimi yokwenza iphepha elimanzi ukuvelisa iphepha lokupakisha ukutya njengeengxowa zeti, iingxowa zekofu, kunyeiphepha lokucoca.
Ngoko ke, xa sigxila kwiimpawu zokusebenza kwezinto ngokwazo, zeziphi iingenelo eziphambili zokusebenzisa i-PLA fiber ekwenzeni iphepha elimanzi?
1. Le nto yenziwe ngokwendalo kwaye inokudibana nokutya
Izinto ezisetyenziswa kwi-polylactic acid fiber zivela kwizityalo ezivuselelekayo. Njengezixhobo eziqinisekisiweyo zokhuseleko lokutya, i-polylactic acid fiber ingasetyenziswa kakhulu kwiintlobo ezahlukeneyo zokutya, amayeza, kunye nezinye izinto ezisetyenziswa ephepheni lasekhaya ezifunwa kakhulu. Ukuthatha ukusetyenziswa kweengxowa zeti kunye nephepha lesihluzi sekofu njengomzekelo, ukuzibeka ngqo emanzini ashushu ngaphandle kokuna kweplastiki okanye ezinye izinto eziyingozi kuluncedo ngakumbi emzimbeni womntu.
2. Ukubola kwezinto eziphilayo
Ukuthatha ukusetyenziswa kweengxowa zeti njengomzekelo, inani elikhulu leengxowa zeti ezilahlwayo zisetyenziswa kwihlabathi liphela yonke imihla. Iingxowa zeti ezenziwe ngezinto zemveli zinomjikelo omde kakhulu wokuwohloka, nto leyo eya kuzisa uxinzelelo olukhulu kwindalo yendalo. Nangona kunjalo, iingxowa zeti okanye ezinye iimveliso ezenziwe ngezinto ze-polylactic acid zinokonakala okugqwesileyo.
Iimveliso zelaphu ezingalukwanga ze-polylactic acid fiber zinokubola ngokupheleleyo zibe yi-carbon dioxide namanzi zizinto ezincinci kwiindawo zendalo ezinobushushu obuthile kunye nokufuma, njengesanti, i-silt, kunye namanzi olwandle. Inkunkuma yemveliso ye-polylactic acid inokubola ngokupheleleyo ibe yi-carbon dioxide namanzi phantsi kweemeko zokwenza umgquba kwimizi-mveliso (ubushushu obuyi-58 ℃, ukufuma okungama-98%, kunye neemeko ze-microbial) kangangeenyanga ezi-3-6; Ukuzalisa inkunkuma kwiindawo zesiqhelo nako kunokufezekisa ukubola kwiminyaka emi-3-5.
3. Ingaxutywa ne-pulp yomthi okanye ezinye iifayibha zendalo ukuze isetyenziswe
Iifayibha ze-polylactic acid zihlala zixutywa ngomlinganiselo othile neefayibha ze-pulp zomthi, ii-nanofibers, njl.njl. ukwenza i-pulp kunye nephepha. I-polylactic acid idlala indima ekudibaniseni nasekuqiniseni, ngokudibanisa ezinye iifayibha ngobushushu kunye nobushushu ukuze kufezekiswe injongo yokubumba kunye nokuqinisa. Ukongeza, ngokulungelelanisa umlinganiselo we-slurry kunye nendlela yokucubungula, inokuhlangabezana neemfuno ezahlukeneyo zeemeko ezahlukeneyo.
4. Ukubopha okushushu kwe-ultrasonic kunokufezekiswa
Ngokusebenzisa iifayibha ze-polylactic acid ukwenza i-pulp kunye nephepha, i-ultrasonic thermal bonding inokufezekiswa kwimveliso elandelayo, engagcini nje ngokusindisa abasebenzi kwaye inciphise iindleko, kodwa ikwaphucula ukusebenza kakuhle kwemveliso.
5. Ukusebenza kokucoca
Iphepha lesihluzi seti elenziwe ngefayibha ye-polylactic acid lisebenza kakuhle ekuhluzeni nasekumanzini, elinokugcina amagqabi eti kunye nezinye iinxalenye eziqinileyo, ngelixa livumela incasa kunye nevumba leti ukuba lingene ngokupheleleyo.
Ukongeza kwiphepha lesihluzi seti, i-polylactic acid fiber ingasetyenziswa nakwiphepha lesihluzi sokupakisha amayeza emveli aseTshayina, iphepha lesihluzi sekofu, kunye namanye amaphepha okupakisha ukutya.
