High Quality DOUBLE SIDE GRAY CHIPBOARD PAPER, GREY CARDBOARD, Duplex Board, Dulpex Paper Board, Coated Duplex Board NeGrey Back, Duplex Board ine Gray Back

Saizi yenguva dzose: 787 * 1092MM, 889 * 1194MM iri chaizvo mustock.Iyo yakajairwa yekuendesa nguva yekugadziriswa uye kukwira ndeye 3-5 mazuva, uye iyo yakasarudzika yakasarudzika yakasarudzika ndeye 7-15 mazuva.

Zvimiro: Pepa repamusoro rakanaka, rakatsetseka uye riri pakati nepakati, nekuomarara kwakanaka, kutwasuka, ukobvu hwakakwana, kuoma uye kusiri nyore kukanganisa.
Nekuda kweiyo yakakosha maitiro uye yakasimba tekinoroji index control, zvese zvigadzirwa zvine huremu huremu, kunaka kuoma, uye hazvisi nyore kukanganisa.Kunyanya mu microwave kuomeswa maitiro, sterilization process inopedzwawo, saka inowedzera uye yakakurumbira muindasitiri yekurongedza chikafu.Kusaziva kwegirini.Pamusoro pechigadzirwa chacho chakatsetseka uye chakapfava, uye kuoma kwacho kwakanaka.

1. Quantitative
Inoreva huremu pachikamu chechikamu chepepa, chinoratidzirwa mu g/m2, kureva, huremu hwegiramu reimwe sikweya mita yepepa.Huwandu hwehuwandu hwebepa hunotaridza humiro hwebepa, senge kusimba kwesimba, kubvaruka, kusimba, kuoma uye ukobvu.Naizvozvo, zvinoenderana nehunhu hwemichina, kuronga huwandu hwemadhinda ezvikamu zvinoenderana nekuita kwayo pakugadzira kunogona kudzikisa zvirinani kudyiwa nekuvandudza kunaka kwechigadzirwa uye kugona kwemidziyo.

2. Hukobvu
Ndiko kukora kwebepa, uye chiyero chekuyera chinowanzo kuratidzwa mu ㎜.Ukobvu hunoenderana zvakanyanya nehuwandu uye kusimba.Kazhinji kutaura, iyo yakakura kukora kwebepa, iyo inowirirana yakakwirira yehuwandu, asi hukama pakati pezviviri izvi hahuna mhedziso.Mamwe mapepa akatetepa, asi hwaro hwawo huremu hwakaenzana kana hunopfuura hweayo akakora.Izvi zvinoratidza kusimba kwefiber chimiro chebepa, icho chinotaridza huremu hwehwaro uye ukobvu hwebepa.Kubva pakuona kwekushandiswa kwekushandisa, zvakakosha zvikuru kuti hupamhi hwepepa yunifomu.Zvikasadaro, zvinokanganisa otomatiki mapepa feed, gluing kuenzana, nezvimwe.

3. Kusimba
Zvinoreva huremu hwebepa pa cubic centimita, mu g/cm3.Kusimba kwepepa kunoverengerwa kubva pahwaro huremu uye ukobvu maererano neiyo inotevera formula: D = G/d * 1000, apo: G inoratidza hwaro huremu hwepepa;g ndiko kukora kwepepa kwe.
Iyo yakasimba ndiyo chiyero chehuwandu hwechimiro chepepa.Kana iyo yakaomeswa yakakura, pepa richava nyore brittle, iyo opacity uye kunwa kwemvura kuchaderedzwa zvakanyanya, uye hazvizove nyore kuoma.
Izvo zvakare zviri nyore kuverenga iyo kadhibhodhi ukobvu zvinoenderana neiyo iri pamusoro formula.Chimiro chayo ndeichi: d = G/D.
Muenzaniso: Tsvaga ukobvu hwe500g/m2 kaviri grey kadhibhodhi (kusimba kwayo tebhu ndeye 0.625g/cm3, inovawo chiratidzo chedu chakajairika).500g/m2÷0.625g/cm3=0.0008m=0.8mm
Iko kutendeuka kwechikwata chem2 uye cm3 chakataurwa munhanho yapfuura inofanira kuchengetwa mupfungwa, kana zvisina kudaro zviri nyore kukonzera kusanzwisisana.Iyo nzira ndeye: cm3 / m2 = (1 * 0.000001) m, yakashandurwa kuita mm ndiko ukobvu hwedu chaihwo.

4. Kuomarara
Ndiko kuita kwebepa rinopesana nekupinzwa kwechimwe chinhu, uye zvakare kushata kwefibrous tissue yepepa.

5. Kupfava
Inoreva chiyero chekusaenzana pamusoro pepepa, inoratidzwa mumasekonzi, iyo inogona kuyerwa.Nheyo yekuona ndeye: pasi peimwe dhigirii yevacuum uye kumanikidzwa, nguva inotora kuti mweya weimwe solvent ipfuure nepapakati pepamusoro peplate yegirazi uye pamusoro peiyo sampuli.Iyo bepa rakatsetseka, mhepo inononoka kupfuura, uye nekukurumidza mhepo ichapfuura.

6. Scaling rate
Zvinoreva kusiyanisa kwedimensional yebepa mushure mekutora mwando kana kurasikirwa nemvura.Iyo yakapfava iyo fiber chimiro chepepa uye yakadzika iyo yakaomeswa, iyo yakakwirira kutambanudza chiyero chebepa;pane zvinopesana, iyo yakaderera chiyero chekutambanudza.

7. Hunyoro hwemukati
Hunyoro hwemukati mumakadhibhodhi.Kazhinji kutaura mwero.Kunyorova kwekaviri grey kadhibhodhi ndeye 8-12%.

8. Vertical and horizontal
Inoreva nzira iyo fibrous tissue yepepa inorongwa.Mukugadzira mapepa, kutungamira kwemafiber pamwe nekumhanya kutungamira kwemuchina wepepa ndiko kureba kwepepa.Inogona kuzivikanwa nekona yakapinza inoratidzwa newebhu mamakisi.Vertical to the vertical direction ndiyo yakachinjika kutungamira, deformation value ye vertical paper pattern idiki, uye uwandu hwekuwedzera nekudhonzwa panguva yekushandiswa kwehorizontal paper pattern yakakura.

9. Air permeability
Kazhinji, iyo yakaonda uye isina kusimba pepa, iyo inowedzera kufema.Chiyero chekupinda kwemhepo ndeye ml/mim kana s/100ml (yechipiri/100ml), zvinoreva huwandu hwemhepo inopfuura nepabepa muminiti 1 kana nguva yainotora kupfuura 100ml yemhepo.

10. Mberi neshure
Munguva yekugadzira mapepa, pulp inonamatira kune mesh yesimbi uye inoratidzirwa nekusefa nekudzikisa mvura.Nenzira iyi, kana rutivi rwemambure rwakarasika nekuda kwekurasikirwa kwemafibers akanaka uye mazadza nemvura, mambure mavara anosara, uye pepa repamusoro rinowedzera.Kune rumwe rutivi, zvakanaka pasina kuvimba nemambure.Smooth, kuitira kuti bepa riite mutsauko pakati pemberi uye kumashure.Kunyangwe yakaomeswa uye yakarongedzerwa mukugadzirwa, kuchine misiyano kumberi nekumashure.
