Kushaya Paper: kushanda uye mhando

Kushaya bepa iri zvinhu kuti anonyanya kuitirwa pakusika yokufananidzira rwezuva mabhuku uye kudhinda kwakajeka zvigadzirwa. The arambe achirema of jira kuti nemichina yokudhinda anoda kubva 60 kusvika 220 g / m. Kazhinji chigadzirwa iri papi sezvo mukuru simba bepa, ikabereka kubva yakaisvonaka cellulose pamwe kwebasa rinofanira pulp, iro rine kuramba deformation pasi pokudzora unyoro.

Sezvo zvaizopedza bepa yaishandiswa rokudhinda indasitiri, ipapo ayo unhu kwokuoma zvinodiwa, izvo zvinokonzerwa Michina yokudhinda. Chinonyanya kukosha parameters zvinosanganisira Rigidity, simba, sizing, absorbency uye ndeiya yakaita kugadzikana panguva hydration.

Nokuti nemichina yokudhinda michina machira neVadzidzi rabha chipande rinoda chigadzirwa kunze STRUCTURAL zvemaziso ehupfumi. Kuwedzera simba zvinhu panguva gadzira, uye kuderedza ayo pylimost vyschipyvaemost. Nokuti pamusoro ichi kadikidiki rinokosha sezvamunoita, umo imwe chirungiso iri wakawedzera fillers.

Kushandisa zvaizopedza bepa sizing anova nani mwando nemishonga. The cellulose fibers vasiri nyore zvinopfuura mvura, asi haina kudzivisa nenzvimbo neingi Absorção de Água. Pfungwa, mashoko Absorção de Água chinonyanya kukosha zvinhu zvokunyama. Kana machira vari isapinda, kuti mwando haagoni kupinda munzvimbo pendi uye achagara pachigaro rabha jira rokudhinda midziyo. Kana parameters kusapfuudza mwero Absorção de Água, chigadzirwa ichatanga kugamuchira dhayi kubva jira humburumbira uye mhaka kunyoroveswa pamusoro pemvura rukoko.

zvaizopedza pepa rinoshandiswa mumabhuku. It awana chikumbiro iri kugadzirwa kwemabhuku, mapepa, mabhurocha, flyers nezvimwe promotional uye zvokushambadzira zvokuvakisa. Uyezve, mashoko akashandiswa bhuku mapepanhau matema-uye-chena uye ruvara uye magazini.

The upenyu webasa kunobva zvaizopedza bepa pulp kugutsikana. Nokuti Kugadzirwa periodicals nani kushandisa machira ane zviri izvi zvinhu havafaniri kupfuudza 75 muzana. Kusunungurwa akadhindwa zvigadzirwa kunoda refu pasherefu upenyu, zvinofanira kutengwa woodfree zvinhu.

Kushaya bepa, mutengo riri kupfuura vamwe zvinhu zvakafanana, rakakamurwa Coated, cartographic, newsprint nemichina. Nokuti kudhinda ruvara mabhuku rasterointi mifananidzo youpenyu refu zvakashandiswa, wakaita kubva bleached yakaisvonaka cellulose.

Uyewo, pepa rakakamurwa mavanga. Category "A" rinoshandiswa kuti pagadzirwe mabhuku, pamwe avhareji ya ukoshi. Mark "B" rinoshandiswa kuti pagadzirwe zvinhu nokungoti ruvara kuparadzana uye kuderedzwa kupenya. Nokuti kugadzirwa mukuru-mugiredhi mapepa akashandisa zvaizopedza bepa rine nani unhu pamwe yakawedzera rikkovia kureba.

Coated machira vanogona Single uye vaviri-kuzviitirwa unhani, paavhareji kumeso, nani yakachenesesa uye kuramba sokunhonga. Izvi rworudzi zvinhu inowanzoshandiswa kusika yokufananidzira zvigadzirwa.
