Iyo Kraft Pepa Pulp ine Qu-Cellulose zvirimo zve97%, intrininsic viscosity ye720ml / g uye average fiber kureba mu9% NAHOL Solution pa40】 kwemasekonzi makumi mashanu. Iyo inokonzeresa pulp yakabva yabuda kuti ibvise yakawandisa ye49% NAHOOOOH Solution yekuwana Alkali Cellulose. Iyo yehuremu ratio ye (49% naoh mumvura) kusvika (chikamu chakasimba muPulpuration Nhanho yaive mazana maviri. Iyo Alkali cellulose (20kg) nokudaro yakawanikwa yakaiswa mune jecketed Pressurance yekunetseka nekukasira uye kucheneswa neiyo nitrogen gasi yekubvisa zvakakwana kubva kune imwe sytor. Zvadaro, tembiricha mune yekunetseka yaidzorwa pa60 ℃, nepo kusimudzira kwemukati kwakaitwa. Zvadaro, 2.4kg of Dimethyl Eherth awedzerwa uye tembiricha mune inodzorwa kuti iwedzerwe neyekuwedzera (methlene Pulp) 1.97, uye tembiricha mune iyo Sterist yakadzorwa kubva pa60 ° C kusvika 80 ° Pashure peChromethane uye tembiricha iri mune yekunetseka yakadzorwa kubva 80 × kusvika 90 ℃ kusvika 90 ℃ kusvika 90 ℃ kusvika 90 Uye zvakare, kuita kwakachengetwa pa 90 ° C kwemaminetsi makumi maviri. Zvadaro, gasi rinodzingwa kubva kune wekutaurirana, uye hydroxypruproproproproproproproproproproproproproproper cellelose yabviswa kubva kune anopinda. Tembiricha yeiyo yakashata hydroxyropropyl methylcellose yaive 62 ℃ kana yabviswa. Kuyera iyo inosvika makumi mashanu muzana saizi mumubatanidzwa wehuremu hwekugovaniswa kwehukuru hwekugovaniswa kwehuswa Nekuda kweizvozvo, iyo avhareji yehukuru hwechikamu chechikamu chakaomesesa ndi 6.2mm. Iyo yakawanikwa yakashata hydroxypropyl methylcellose yakaunzwa kuenderera mberi kweBiaders (K3ADE KENDUME 00RPM) PAMWE Sezvakayerwa nenzira yakafanana uchishandisa screens mashanu ane akasiyana siyana ekuvhura saizi, iyo avhareji yehukuru hwakaita 1.4mm. Iyo slurry yakawanikwa nekuwedzera mvura inopisa pa 80 ° C kune yakagadzirirwa Hydroxproplose Control Hydroxproproproproproproproplose Iyo slurry yakakurudzirwa pakudziya nguva dzose kwe80 ° C kwemakore makumi matanhatu. Zvadaro, iyo slurry inopiwa kune iyo rotary inomiririrwa firita (BHS sonthofen chigadzirwa) nekumhanya kwekutenderera kwe0.5 rpm uye yakatsvuka. Tembiricha yeiyo slurry yaive 93 ℃. Iyo slurry inopihwa pombi ine kudzvinyirira kwe 0.2mpa. Saizi yakavhurwa yeiyo rotary inomanikidza iyo 80μm, uye nzvimbo yeFiltration ndeye 0.12m2. Iyo slurry inopihwa kune iyo rotary dzvinyiriro yekumanikidza inoitwa kuburikidza nefaira uye yakashandurwa kuita keke yefaira. Keke yakakonzerwa yakapihwa neyakawa ne1.3mpa uye mvura inopisa pa 95 ° C to A one (,0 kune yakasimba chikamu cheHydroxproproprollose uye yakazotendeuka kuburikidza nefaira. Mvura inopisa inopihwa pombi ine kudzvinyirira kwe 0.2mpa. Mushure mekunge mvura inopisa ichipa, 0.3mpa yeSteam inopiwa. Iyo yakashambidzwa chigadzirwa pamusoro pefaira yabviswa kuburikidza neyechikamu ndokudzingwa muWasher. Kuenderera mberi nhanho kubva pakuwanikwa kweiyo slurry kune iyo discharge yeiyo yakashambidzwa chigadzirwa. Iyo yemvura yemvura yeiyo yakageda chigadzirwa yaive 52.8% sekuyerwa nekudziya kupisa hutschrometer. Zvigadzirwa zvakashambwa zvinobva kuDhional Pressure Filter zvakaomeserwa uchishandisa mhepo yakaoma pa 80 ° CLACT MENTRORT GRDROPPROPLELLLELLELLELLELELLELELLELELLELELLELLELELLELELLELELLELELLELLELLELELLELLELELLELELLELELLELELLELELLELLELLELLELLELELLELELLELLELLELLELLELLELELLELELLELLELLELELLELLELLELE.
