Izithako eziyinhloko zotshani lukakolweni yi-cellulose, i-semi-cellulose, i-lignin, i-polyfrin, amaprotheni namaminerali. Phakathi kwazo, okuqukethwe kwe-cellulose, i-semi-cellulose, ne-lignin kuphezulu njenge-35% kuya ku-40%. Izithako ezisebenzayo yi-cellulose ne-semi-cellulose.
Isinyathelo sokuqala ekukhiqizweni kwe-tableware ukuklebhula nokuxova utshani. Sebenzisa ibhande lokuthutha ukuthumela utshani lukakolweni emshinini wokudabula i-floss. Ngemuva kokuthi umshini usulashiwe, utshani buzoba ngu-3 kuya ku-5 cm ubude, ukuthungwa okuthambile. Faka amakhilogremu angama-800 wamanzi ku-1,000 kg wotshani emanzini amanzi, bese unqwabelana amahora angama-48 kuya kwangama-50 kuze kube yilapho utshani sebumanzi ngokuphelele futhi buthambile, futhi ungangena inqubo ephansi.
Utshani obuthambile bukakolweni buzogezwa futhi buhlukaniswe emshinini wotshani obusebenza ngamanzi. Lapho utshani bungena emshinini wotshani obusebenzisa amanzi, amanzi ajikelezayo ayengezwa ngesikhathi esifanayo ukuze kulawulwe ukugcwala kwamanzi otshani okuhlanganisa uketshezi kuze kufike ku-10%. Ngemuva kokwelashwa, imikhosi yesihlabathi, amaqabunga, ama-spikes, notshani otshanini bukhishwa ngamanzi ngemva kokuphulwa. Izinto ezisindayo njengamatshe namabhulokhi ensimbi akhishwa eshubhuni lamatshe elizungezile ngaphansi kwesenzo se-centrifugal force. Ekugcineni, okusele kuhlanzekile. Izingcezu zohlanga.
I-Lyrin iyinto eyinhloko ekhona kungqimba lwe-cytoplasm. Ivumela amaseli ukuthi anamathele kwelinye futhi aqine. Ukuze uthole i-cellulose ne-semi-cellulose efanelekile ku-tableware, kuyadingeka ukuyihlukanisa ne-lignin, ukususa i-lignin noma ukuyisula noma ukuyisula noma ukuyisula. Phula ushingamu ngekhwalithi yokhuni. Ngokwesimiso sokuwohloka ekushiseni okuthile, utshani lungahlukaniswa lube imicu ngosizo lomshini wokubola utshani. Ngesikhathi sokwelashwa kwe-120 ° C kuya ku-140 ° C, i-lignin iguqulwa isuka esimweni sengilazi esicwebezelayo ibe yisimo senjoloba esithambile kakhulu, esihlanganiswe eduze ne-cellulose ne-semi-cellulose. Amandla wokuhlanganisa we-tableware.
Ngemuva kwe-decomposer yotshani, ingxube yamanzi otshani ithunyelwa ohlelweni lokuwasha ukuze kuhlanzwe futhi kugxilwe, kusale kuphela i-cellulose, i-semic cellulose kanye ne-transgender lignin. Ngemuva kokuhlanza i-slurry, kuyadingeka ukuthi uqhubeke ugoqa nge-extruder ukuze uthole izinto zokusetshenziswa zamatafula otshani. Nakuba ukwelashwa kwangaphambilini, kusekhona inkinga engakaxazululwa, okungukuthi, izinkinga ze-pigment otshanini bakakolweni. Ngenxa yokuthi utshani lukakolweni ngokwalo luphuzi, umbala ophuzi ucwiliswa ngemva kwamanzi ashisayo. Ungasulwa kanjani lombala? Njengoba amanzi ashisayo angafakwa embala, umbala ungasuswa ngokupheka. Ngaphansi kwesenzo samanzi ashisayo ku-96 ° C, i-pigment ku-fiber iyacwiliswa. Inqubo ayinakuhlehliswa. Ngemuva kokupheka okuningana, i-straw fiber slurry etholakele ingasetshenziswa ukukhiqiza i-tableware.
Ethangini lesithako, engeza amanzi anesisindo esiphelele esiphindwe izikhathi ezingama-50 kuye kwangama-60 kunesisindo sotshani, bese wengeza u-5% kuya ku-8% wokuvikela amanzi kanye no-0.8% -i-ejenti efaka uwoyela ngokwesisindo esiphelele sempahla eluhlaza. , bese uwunyakazisa ube yi-pulp efanayo ukuze uyisebenzise kamuva. Ukudla kwesikhathi esisodwa kunezidingo zekhwalithi ezibaluleke kakhulu, okungukuthi, amanzi anesobho achumayo awakwazi ukuvuza, futhi ukudla okunamafutha akukwazi ukuvuza. Ngakho-ke, kuyadingeka ukwengeza inani elifanele le-oyili-ubufakazi kanye ne-ejenti yokuvimbela amanzi, kodwa kufanele kube isengezo sebanga lokudla. I-slurry elungisiwe ithuthelwa endaweni yokumisa kanye nomshini wokubumba we-tableware elahlwayo ngepayipi. Uma usetha, faka isikhunta sediski lokudla esenziwe ngenethiwekhi yensimbi emshinini, bese ulahla umshini. Ngemuva kokuthi i-slurry ikhishwe ngokulinganayo esitsheni, vula inkinobho yepompo ye-vacuum. I-slurry esitsheni izowa kancane kancane. Isiyalo. Le ndlela ingasusa amanzi amaningi ku-slurry, ukuze izithako eziqinile ku-slurry zihlanganiswe ngokulinganayo odongeni lwangaphakathi lwesikhunta. Uma iswishi ivaliwe ukukhipha isikhunta semeshi yensimbi, i-pulp emanzi ingasuswa. Khona-ke, umbungu omanzi we-pulp wawudluliselwa emshinini wokusetha we-tableware, futhi kwakukhona isikhunta kumafolda aphezulu nangaphansi. Lapho isikhunta esingenhla nesingaphansi siboshelwe ndawonye, isitimu sisuka ku-170 ° C siye ku-180 ° C, futhi okuqukethwe kwamanzi ku-tableware kwafinyelela cishe ku-8% ngokusebenzisa indlela yokucindezela ukushisa. Ngalesi sikhathi, i-tableware yaqala ukusetshenziswa.
Ngemuva kwe-tableware yokubumba, imiphetho ayilingani futhi ithinta ubuhle. Ngakho-ke, kuyadingeka ukukhiqiza umsiki ophelele ngenqubo yokusika. Izibunjwa ezisetshenziswa emshinini womngcele zifana ncamashi nesikhunta, kanye nesikhunta emshinini wokubumba. Ngemuva kokulungisa i-tableware, umshini uyavulwa, futhi imiphetho eyeqile ye-tableware iyagxivizwa, okuba i-tableware engasetshenziswa.
Ngaphambi kokuphuma embonini, i-straw tableware kufanele ihlolwe, ibulawe amagciwane futhi ihlanganiswe. Kule nqubo, ikhwalithi yokubukeka kufanele ihlolwe; ngaphezu kwalokho, iqoqo ngalinye le-tableware kufanele lenziwe, futhi okuqukethwe kokuhlolwa kwesampula kuhlanganisa izakhiwo ezibonakalayo zemishini kanye nezinkomba ze-microbial. Nakuba i-straw tableware inezindinganiso eziqinile zokulawula impilo ekukhiqizweni, ukukhishwa kwe-ozone kanye nokubulala amagciwane e-ultraviolet kufanele kwenziwe ngaphambi kwefekthri ukuze kubulawe umzimba wokuzala wamagciwane phezu kwe-tableware efana nezinhlamvu nesikhunta.
