Sechimwe chezvinwiwa zvitatu zvikuru pasi rose zvisiri doro, tii inofarirwa zvikuru nevanhu nekuda kwehunhu hwayo hwekuzvarwa, hunovaka muviri, uye hunosimudzira hutano. Kuti unyatso chengetedza chimiro, ruvara, kunhuhwirira, uye kuravira kwetii, uye kuwana yenguva refu yekuchengetedza uye yekufambisa, kurongedza kwetii zvakare kwakagadziridzwa kwakawanda uye hunyanzvi. Kubva payakavambwa, tii yakabhegi yave yakakurumbira munyika dzeEurope neAmerica nekuda kwezvakanakira zvakawanda zvakaita sekureruka uye hutsanana.
Bagged tii imhando yetii inoiswa mumabhegi matete emapepa emapepa uye akaiswa pamwe chete nebhegi rebepa mukati metii seti. Chinangwa chikuru chekurongedza nemasefa mapepa mabhegi ndechekuvandudza chiyero cheleaching uye zvakare kushandisa zvizere hupfu hwetii mufekitori yetii. Nekuda kwemabhenefiti ayo akadai sekubika kubika nekukurumidza, kuchena, chiyero chakajairwa, kusanganisa nyore, nyore kubvisa zvakasara, uye kutakurika, bagged tii inofarirwa zvakanyanya mumusika wepasirese kuti isangane nehupenyu hwekukurumidza hunodiwa nevanhu vemazuva ano. Zvigadzirwa zvetii, zvekurongedza, uye michina yekurongedza yetii bhegi rekugadzira zvinhu zvitatu zvekugadzira bhegi reti, uye zvekurongedza zvinhu ndiwo mamiriro ekutanga ekugadzira bhegi reti.
Mhando uye zvinodiwa zvekutakura zvinhu zvemabhegi eti
Zvinhu zvekurongedza zvemabhegi eti zvinosanganisira zvemukati zvekurongedza zvinhu zvakaita setea filter paper, zvekunze zvekurongedza zvinhu zvakaita semabhegi ekunze, mabhokisi ekurongedza, uye yakajeka epurasitiki uye girazi bepa, pakati peiyo tii sefa bepa ndiyo inonyanya kukosha yakakosha zvinhu. Uye zvakare, panguva yese yekurongedza maitiro emabhegi eti, bhegi retishinda yekotoniyekusimudza shinda, pepa rezita, kusimudza shinda yekunamira, uye acetate polyester adhesive yemavara inodiwa zvakare. Tea inonyanya kuve nezvikamu zvakaita se ascorbic acid, tannic acid, polyphenolic compounds, makatechini, mafuta, uye carotenoids. Izvi zvinongedzo zvinonyanya kukanganiswa nekuipa nekuda kwehunyoro, okisijeni, tembiricha, chiedza, uye kunhuhwirira kwezvakatipoteredza. Naizvozvo, zvinhu zvekurongedza zvinoshandiswa pamabhegi etii zvinofanirwa kusangana nezvinodiwa zvekudzivirira hunyoro, kuramba kweokisijeni, kupisa kwakanyanya, kudzivirira kwemwenje, uye kuvharira gasi kudzikisa kana kudzivirira kukanganiswa kwezvinhu zviri pamusoro.

Tea bhegi rekusefa bepa, iro rinozivikanwawo setii bhegi rekurongedza bepa, ibepa rakatetepa huremu rine yunifomu, yakachena, yakasununguka uye ine porous chimiro, yakaderera tightness, kunyura kwakasimba, uye yakanyanya kunyorova simba. Iyo inonyanya kushandiswa kugadzira uye kurongedza kwe "tii mabhegi" mune otomatiki tii kurongedza michina. Inotumidzwa zita rechinangwa chayo, uye kuita kwayo uye kunaka kunoita basa rakakosha mumhando yemabhegi etii apera.
1.2 Zvinodiwa zvekutanga zvetii sefa bepa
Sezvinhu zvekurongedza zvemabhegi etii, pepa refirita retii harifanire kungove nechokwadi chekuti zvimisikidzo zvinoshanda zvetii zvinogona kukurumidza kupararira mumuto wetii panguva yekubikirwa, asi zvakare kudzivirira hupfu hwetii mubhegi kuti usapinda muto retii. Izvo zvinodikanwa zvehunhu hwayo ndezvinotevera.
(l) Iine simba rakakwana remagetsi (yakakwirira simba rekusimba) kuti rienderane nekuoma kwesimba uye elasticity yemashini ekurongedza otomatiki emabhegi eti;
(2) Kugona kumira kunyudzwa mumvura iri kufashaira pasina kutyoka;
(3) Tii yakabikwa ine hunhu hwekuva porous, hunyoro, uye kupinza. Mushure mekubika, inogona kukurumidza kunyorova uye izvo zvinonyunguduka zvetii zvinogona kuburitswa nekukurumidza;
(4) Iyo fiber inofanira kuva yakanaka, yakafanana uye yakafanana.
Ukobvu hwepepa resefa kazhinji 0.003-0.009in (lin=0.0254m)
Kukura kwepore kwepepa resefa kunofanirwa kunge kuri pakati pe20-200 μ m, uye kuwanda uye porosity yepepa resefa kunofanirwa kuenzana.
(5) Kusanhuhwirira, kusanhuwa, kusiri muchetura, mukutevedzera zvinodiwa nehutsanana;

1.3 Mhando dzeTea Sefa Pepa
Zvinhu zvekurongedza zvemabhegi etii munyika nhasi zvakakamurwa kuita marudzi maviri:kupisa kwakavharwa tii sefa bepauye isina kupisa yakavharwa tii sefa pepa, zvichienderana nekuti ivo vanoda kudziirwa uye kusungwa panguva yekuvharwa kwebhegi. Iyo inonyanya kushandiswa parizvino kupisa yakavharwa tei sefa bepa.
Kupisa kwakavharwa tii sefa pepa imhando yetii sefa bepa yakakodzera kurongedza mukupisa yakavharwa tii otomatiki yekurongedza michina. Inodiwa kuti iumbwe ne30% -50% yakareba fiber uye 25% -60% inopisa yakavharwa fibers. Basa remafibhi akareba kupa simba rakakwana remagetsi kusefa bepa. Mafiber akavharidzirwa anopisa anosanganiswa nemamwe mafiber panguva yekugadzirwa kwepepa resefa, zvichibvumira zvidimbu zviviri zvepepa resefa kuti zvibatane pazvinenge zvadziyirwa uye zvamanikidzwa nemuchina wekurongedza weheat sealing rollers, zvichigadzira bhegi rakavharwa kupisa. Iyi mhando yefiber ine kupisa sealing properties inogona kugadzirwa kubva kucopolymers epolyvinyl acetate uye polyvinyl chloride, kana kubva ku polypropylene, polyethylene, sirika yekugadzira, uye misanganiswa yavo. Vamwe vagadziri vanogadzirawo rudzi urwu rwesefa kuti ive yakapetwa kaviri-layer dhizaini, ine imwe layer inosanganisirwa yese yekupisa yakavharidzirwa yakasanganiswa fiber uye imwe layer ine isina kupisa yakavharwa fiber. Kubatsira kweiyi nzira ndeyekuti inogona kudzivirira kupisa kwakavharwa fiber kubva pakunamatira kune yekuisa chisimbiso rollers yemuchina mushure mekunyungudutswa nekupisa. Ukobvu hwepepa hunotarwa zvichienderana nechiyero che17g/m2.
Isiri kupisa yakavharwa sefa pepa itii sefa bepa rakakodzera kurongedza mune isiri kupisa yakavharwa tii otomatiki yekurongedza michina. Isiri kupisa yakavharwa tii sefa bepa inodiwa kuve ne30% -50% refu fibers, senge Manila hemp, kuti ipe simba rakakwana remuchina, nepo imwe yacho inoumbwa neakachipa mapfupi fiber uye angangoita 5% resin. Basa resin nderekuvandudza kugona kwepepa resefa kuti rimire kubikwa kwemvura inofashaira. Ukobvu hwayo hunowanzo temwa zvichibva pahuremu hwemagiramu gumi nemaviri paskweya mita. Vatsvagiri kubva kuDhipatimendi reSango Zviwanikwa Sainzi paShizuoka Agricultural University kuJapan vakashandisa chiChinese chakagadzira hemp bast fiber yakanyikwa mumvura seyakabikwa, uye vakadzidza zvimiro zvehemp bast fiber pulp inogadzirwa nenzira nhatu dzakasiyana dzekubika: alkaline alkali (AQ) pulping, sulfate pulping, uye atmospheric alkaline pulping. Zvinotarisirwa kuti mumhepo alkaline pulping yehemp bast fiber inogona kutsiva Manila hemp pulp mukugadzirwa kwebepa retii.
Pamusoro pezvo, kune marudzi maviri etii sefa bepa: bleached uye isina kuchena. Kare, tekinoroji yechloride bleaching yaishandiswa, asi parizvino, oxygen bleaching kana bleached pulp inonyanya kushandiswa kugadzira tii sefa bepa.
MuChina, mulberry bark fibers inowanzogadzirwa nepamusoro yemahara state pulping uye yozogadziriswa neresin. Mumakore achangopfuura, vatsvakurudzi vekuChina vakaongorora nzira dzakasiyana-siyana dzekupurudzira zvichienderana nekucheka kwakasiyana, kuzvimba, uye kunaka kwefiber mhedzisiro yefiber panguva yekupuruzira, uye vakaona kuti yakanakisa nzira yekupuruzira yekugadzira tei bepa bepa pulp "refu fiber isina pulping". Iyi nzira yekurova inonyanya kutsamira pakuonda, kucheka zvakafanira, uye kuedza kuchengetedza kureba kwemafibhi pasina kuda yakawandisa fibre yakanaka. Hunhu hwebepa kunyura kwakanaka uye kufema kwakanyanya. Nekuda kwemafibhi akareba, kufanana kwepepa kwakashata, pamusoro pepepa hachina kutsvedzerera, opacity yakakwira, ine simba rakanaka kubvarura uye kusimba, kusimba kwepepa kwakanaka, uye deformation iri. diki.
