Ntau tus neeg siv khoom xav tias kev ua haujlwm ntawm kev tsim cov ntawv thiab cov ntawv tais ntim khoom yog tib yam, tab sis qhov tseeb, kev tsim cov ntawv thiab cov tais ntawv yog qhov sib txawv ntawm qhov ntau lawm. Cov hauv qab no yog qhov zoo sib xws ntawm daim ntawv tais daim ntawv ua thiab daim ntawv tais ntau lawm:
(1) Cov ntaub ntawv tsim khoom yog tib yam. Ob qho tib si pulp molding ntau lawm thiab daim ntawv thiab cov ntaub ntawv ntau lawm tuaj yeem siv cov ntaub ntawv yooj yim, xws li reed, bagasse, nplej straw thiab lwm yam herbaceous cog fiber ntau los yog cov ntaub ntawv pov tseg. Cov tshuaj auxiliaries siv nyob rau hauv cov txheej txheem ntau lawm yeej ib txwm zoo ib yam, xws li retention aids, filter aids, wet zog agents, dry strength agents, water repellants, oil repellent, dyes, brighteners, etc. Tseem muaj cov ntaub ntawv zoo ib puag ncig los ua cov ntaub ntawv zoo ib puag ncig.
(2) Cov khoom siv thev naus laus zis thiab cov khoom siv raw khoom yog tib yam. Yog tias siv cov ntaub ntawv pov tseg los tsim cov duab los qhia, nws yuav tsum mus dhau ntawm cov ntawv pov tseg, hydraulic pulper crushing, ntaus tshuab lossis refiner pulping, thiab pulp sizing. Lub pulping thiab lwm yam txheej txheem yog ces pumped mus rau daim ntawv tshuab rau daim ntawv sau, squeezing thiab dewatering, thiab ziab lub tog raj kheej kom qhuav cov txheej txheem los ua daim ntawv tiav cov khoom. Pulp molding ntau lawm siv nplej straw pulp los yog cov ntawv pov tseg raws li cov ntaub ntawv raw, uas yuav tsum tau tawg los ntawm hydraulic pulper, pulper los yog refiner, pulp sizing, pulping thiab lwm yam txheej txheem, thiab ces thauj mus rau cov ntawv yas molding tshuab rau molding, Extrusion, lub cev qhuav dej, ziab thiab shaping, thiab lwm yam. Cov khoom siv raw khoom ua haujlwm hauv ob txoj kev tsim khoom tuaj yeem siv tau ntau yam, tab sis lawv txawv ntawm kev tsim thiab ziab khoom.
(3) Lub hauv paus ntsiab lus tsim yog zoo sib xws, tab sis daim ntawv ntawm cov khoom tiav yog txawv. Pulp molding ntau lawm thiab daim ntawv thiab cov ntaub ntawv ntau lawm yog ob qho tib si tsim los ntawm cov txheej txheem ntub dej, thiab tom qab ntawd lub cev qhuav dej thiab qhuav rau hauv cov khoom tiav. Qhov sib txawv ntawm cov txheej txheem kev tsim cov ntaub qhwv thiab cov txheej txheem tsim cov ntaub ntawv ib txwm yog tias daim ntawv lossis cov duab los qhia yog "txhaj" lossis "ntses" mus rau qhov sib sau (hlau net lossis yas net) hauv qhov ntub dej ntawm daim ntawv ua tshuab rau lub cev qhuav dej thiab tsim. , Daim ntawv ntub dej thiab cov khoom tiav qhuav yog tag nrho cov kab nrib pleb tiaj tus, thiab dov rau hauv ib lub yob -zoo li daim ntawv.
Qhov sib txawv ntawm daim ntawv ua thiab cov ntawv tais ntau lawm: cov khoom tsim thiab ziab yog txawv. Daim ntawv ua tshuab rau ntawv lossis duab los qhia yog feem ntau loj - cov cuab yeej ntsuas uas sib sau ua ke thiab ziab.
