Njengenye yeziselo ezithathu zehlabathi ezingezizo utywala, iti ithandwa kakhulu ngabantu ngenxa yendalo yayo, inezondlo, kunye neempawu zayo ezikhuthaza impilo. Ukuze ulondoloze ngokufanelekileyo imilo, umbala, ivumba, kunye nencasa yeti, kwaye ufezekise ukugcinwa kwexesha elide kunye nokuthutha, ukupakishwa kweti kuye kwahlaziywa ngeendlela ezininzi kunye nezinto ezintsha. Ukusukela oko yaqalayo, iti ebhegi idumile kumazwe aseYurophu naseMelika ngenxa yeengenelo zayo ezininzi ezifana nokulula kunye nococeko.
Iti ephathwayo luhlobo lweti olupakishwe kwiibhegi zephepha lokucoca olucekethekileyo kwaye lubekwe kunye nebhegi yephepha ngaphakathi kwiseti yeti. Eyona njongo yokupakisha ngeengxowa zephepha lokucoca kukuphucula izinga lokuvuza kunye nokusebenzisa ngokupheleleyo umgubo weti kumzi-mveliso weti. Ngenxa yeengenelo zayo ezinjengokwenza utywala okukhawulezayo, ucoceko, idosi esemgangathweni, ukuxuba ngokulula, ukususwa kwentsalela ekulula ukuyiphatha, kunye nokuphatheka, iti efakwe engxoweni ithandwa kakhulu kwimarike yamazwe ngamazwe ukuhlangabezana neemfuno zokuphila ezikhawulezayo zabantu banamhlanje. Imathiriyeli ekrwada yeti, izinto zokupakisha, kunye noomatshini bokupakisha ibhegi zizinto ezintathu zokuvelisa ibhegi yeti, kwaye izinto zokupakisha ziimeko ezisisiseko zokuvelisa ibhegi yeti.
Iintlobo kunye neemfuno zezinto zokupakisha kwiingxowa zeeti
Izinto zokupakisha zeebhegi zeti ziquka izinto zokupakisha zangaphakathi ezifanaiphepha lokucoca iti, izinto zokupakisha zangaphandle ezifana neengxowa zangaphandle, iibhokisi zokupakisha, kunye neplastiki ecacileyo kunye nephepha leglasi, phakathi kwayo i-tea filter paper iyona nto ibaluleke kakhulu. Ukongeza, ngexesha lenkqubo yokupakisha yonke yeebhegi zeeti, ibhegi yetiyiintambo yomqhaphuukuphakamisa intambo, iphepha lelebhile, ukuphakamisa intambo yokuncamathelisa, kunye ne-acetate polyester adhesive for labels nazo ziyafuneka. Iti ikakhulu iqulathe amacandelo anjenge ascorbic acid, tannic acid, iikhompawundi zepolyphenolic, iikatechin, amafutha, kunye necarotenoids. Ezi zithako zisesichengeni kakhulu sokuwohloka ngenxa yokufuma, ioksijini, ubushushu, ukukhanya, kunye nevumba lokusingqongileyo. Ke ngoko, izinto zokupakisha ezisetyenziselwa iibhegi zeti kufuneka zihlangabezane neemfuno zokumelana nokufuma, ukumelana neoksijini, ukumelana nobushushu obuphezulu, ukhuselo lokukhanya, kunye nokuthintela igesi ukunciphisa okanye ukuthintela impembelelo yezi zinto zingasentla.
1. Izinto zokupakisha zangaphakathi kwiingxowa zeeti - iphepha lokucoca itiye
Iphepha lokucoca ibhegi yeti, ekwaziwa njengephepha lokupakisha ibhegi, liphepha elincinci elincinci elineyunifomu, ecocekileyo, ekhululekileyo kunye nesakhiwo esinamaqhuqhuva, ukuxinana okuphantsi, ukufunxa ngamandla, kunye namandla aphezulu amanzi. Isetyenziselwa ikakhulu ukuvelisa kunye nokupakishwa "kweebhegi zeti" koomatshini bokupakisha iti abazenzekelayo. Ithiywe ngegama lenjongo yayo, kwaye ukusebenza kwayo kunye nomgangatho wayo kudlala indima ebalulekileyo kumgangatho weebhegi zeti ezigqityiweyo.
1.2 Iimfuno ezisisiseko zephepha lokucoca iti
Njengezinto zokupakisha iibhegi zeeti, iphepha lokucoca iti akufanele liqinisekise kuphela ukuba izithako ezisebenzayo zeti zinokusasazeka ngokukhawuleza kwisuphu yeti ngexesha lenkqubo yokusela, kodwa kwakhona ukuthintela umgubo weti engxoweni ukuba ungangeni kwisuphu yeti. Iimfuno ezithile zeempawu zayo zilandelayo.
(l) Unamandla aneleyo omatshini (amandla aphezulu okuqina) ukuqhelanisa ukomelela okomileyo kunye nokunwebeka koomatshini bokupakisha okuzenzekelayo kwiingxowa zeti;
(2) Ukwazi ukumelana nokuntywiliselwa emanzini abilayo ngaphandle kokwaphuka;
3 Emva kokuphuza, kunokumanziswa ngokukhawuleza kwaye iziqulatho ezinyibilikayo zeti zinokukhutshwa ngokukhawuleza;
(4) Imicu kufuneka ilunge, ifane kwaye ihambelane.
Ubukhulu bephepha lokucoca ngokuqhelekileyo yi-0.003-0.009in (lin=0.0254m)
Ubungakanani bepore yephepha lokucoca kufuneka libe phakathi kwe-20-200 μ m, kwaye ubuninzi kunye ne-porosity yephepha lokucoca kufuneka lilinganiswe.
(5) Ayinavumba, ayinavumba, ayinabungozi, ithobela iimfuno zococeko;
(6) Ikhaphukhaphu, nephepha elimhlophe.
1.3 Iindidi zePhepha lesiSihluzo seTea
Izinto zokupakisha iibhegi zeti kwihlabathi namhlanje zohlulwe zibe ziindidi ezimbini:iphepha lokucoca iti elivaliweyokunye nephepha lokucoca iti elingenabushushu elitywiniweyo, kuxhomekeke ekubeni kufuneka zifudunyezwe kwaye zibotshwe ngexesha lokutywinwa kwengxowa. Eyona isetyenziswayo ngoku liphepha elitywiniweyo lokucoca iti.
Ubushushu obutywiniweyo bephepha lokucoca iti luhlobo lwephepha lokucoca iti olulungele ukupakishwa kubushushu obutywinwe ngobushushu kumatshini wokupakisha ozenzekelayo. Kufunwa ukuba kuqulunqwe i-30% -50% ye-fibers emide kunye ne-25% -60% yeefayili ezivaliweyo zokushisa. Umsebenzi wemicu emide kukubonelela ngamandla aneleyo omatshini wokucoca iphepha. Iintsinga ezivaliweyo zobushushu zixutywe kunye nezinye iintsinga ngexesha lokuveliswa kwephepha lokucoca, livumela iileya ezimbini zephepha lokucoca ukuba zibophe kunye xa zifudunyezwa kwaye zinyanzeliswa yi-roller yokutywina ubushushu bomshini wokupakisha, ngaloo ndlela yenze isikhwama esivaliweyo sobushushu. Olu hlobo lwefiber kunye neempawu zokutywinwa kobushushu zingenziwa kwi-copolymers ye-polyvinyl acetate kunye ne-polyvinyl chloride, okanye kwi-polypropylene, i-polyethylene, i-silk yokwenziwa, kunye nemixube yabo. Abanye abavelisi nabo benza olu hlobo lwephepha lokucoca lube kulwakhiwo oluphindwe kabini, kunye nomaleko omnye oqulathe ngokupheleleyo ubushushu obutywiniweyo bemicu edityanisiweyo kunye nolunye umaleko olubandakanya iintsinga ezingavalwanga bubushushu. Inzuzo yale ndlela kukuba inokuthintela imicu evaliweyo yobushushu ukuba ibambelele kwii-roller zokutywinwa komatshini emva kokuncibilika ngokutshisa. Ubunzima bephepha bunqunywe ngokwemigangatho ye-17g / m2.
Iphepha lokucoca elingenabushushu elitywiniweyo liphepha lokucoca iti elilungele ukupakishwa koomatshini bokupakisha obungenabushushu obuvaliweyo. Iphepha lokucoca iti elingavalwanga ngobushushu liyafuneka ukuba liqulathe i-30% -50% yemicu emide, efana neManila hemp, ukunika amandla aneleyo omatshini, ngelixa elinye liqulunqwe ziintsinga ezimfutshane ezingabizi kakhulu kwaye malunga ne-5% yentlaka. Umsebenzi we-resin kukuphucula amandla ephepha lokucoca ukumelana nokubiliswa kwamanzi abilayo. Ukutyeba kwayo ngokuqhelekileyo kunqunywe ngokusekelwe kubunzima obuqhelekileyo be-12 grams ngemitha yesikwere. Abaphandi abavela kwiSebe lezeNzululwazi yezaMahlathi kwiYunivesithi yezoLimo yaseShizuoka eJapan basebenzise i-fiber yaseTshayina eyenziwe nge-hemp bast efakwe emanzini njengezinto ezikrwada, kwaye bafunda iipropathi ze-hemp bast fiber pulp eziveliswe ngeendlela ezintathu ezahlukeneyo zokupheka: ialkaline alkali (AQ) pulping, I-sulfate pulping, kunye ne-atmospheric alkaline pulping. Kulindeleke ukuba iatmospheric alkaline pulping of hemp bast fiber ingathatha indawo yeManila hemp pulp ekuvelisweni kwephepha lokucoca iti.
Ukongeza, kukho iintlobo ezimbini zephepha lokucoca iti: i-bleached kunye ne-unbleached. Ngaphambili, iteknoloji ye-chloride bleaching yayisetyenziswa, kodwa okwangoku, i-oxygen bleaching okanye i-pulp efakwe i-bleached isetyenziswa kakhulu ukuvelisa iphepha lokucoca iti.
E-China, iifayibha zamaxolo e-mulberry zihlala zenziwe ngokucolwa kwe-high free state kwaye zicocwe nge-resin. Kwiminyaka yakutsha nje, abaphandi baseTshayina baphonononge iindlela ezahlukeneyo zokutyhaphaza ngokusekwe kwindlela eyahlukileyo yokusikwa, ukudumba, kunye neziphumo ezintle zefiber zefiber ngexesha lokucofa, kwaye bafumanisa ukuba eyona ndlela ilungileyo yokucofa ukwenza i-pulp yephepha leti yeti “yi-fiber ende esimahla”. Le ndlela yokubetha ixhomekeke kakhulu ekunciphiseni, ukusika ngokufanelekileyo, kunye nokuzama ukugcina ubude beentsinga ngaphandle kokufuna imicu ecolekileyo kakhulu. Iimpawu zephepha kukufunxa kakuhle kunye nokuphefumla okuphezulu. Ngenxa yeentsinga ezinde, ukufana kwephepha akubi kakuhle, umphezulu wephepha awugudi kakhulu, i-opacity iphezulu, inamandla amahle okukrazula kunye nokuqina, ukuzinza kobungakanani bephepha kulungile, kwaye ukuguqulwa encinci.
