Paper trays yog ib puag ncig tus phooj ywg cov khoom ntawm ntau hom thiab siv los ntawm kev tsim thiab ua ntawm ntau yam ntaub ntawv raw. Tam sim no lawv yog ib puag ncig tus phooj ywg ntim khoom uas tau siv dav hauv ntau lub teb. Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm cov ntawv ntim khoom thiab cov duab los qhia?
1. Qhov zoo sib xws thiab qhov sib txawv ntawm papermaking thiab daim ntawv tais ntau lawm:
Cov ntaub ntawv raw rau kev tsim cov ntawv tais yog qhov zoo ib yam: pulp molding ntau lawm thiab daim ntawv thiab cov duab los qhia tuaj yeem siv cov ntaub ntawv yooj yim, xws li reed, bagasse, nplej straw thiab lwm yam herbaceous cog fiber ntau lossis cov ntaub ntawv pov tseg rov ua dua tshiab. Cov tshuaj additives siv nyob rau hauv cov txheej txheem tsim khoom kuj tseem zoo ib yam, xws li cov khoom siv khaws cia, cov khoom siv lim dej, cov khoom siv ntub dej, cov tshuaj muaj zog qhuav, cov tshuaj tua dej, cov roj pleev xim, cov tshuaj pleev xim, cov khoom ci ci, thiab lwm yam.
2. Cov khoom siv thev naus laus zis thiab cov cuab yeej siv tau zoo ib yam:
Yog tias daim ntawv tais yog ua los ntawm 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 zoo ib yam:
Txawm hais tias txoj hauv kev tsim cov ntawv tais thiab cov duab los qhia zoo ib yam, daim ntawv ntawm cov khoom tiav yog txawv. Ob daim ntawv tais ntau lawm thiab daim ntawv thiab cov duab los qhia yog tsim los ntawm kev ntub dej, tom qab ntawd lub cev qhuav dej thiab qhuav rau hauv cov khoom tiav. Qhov txawv yog tias daim ntawv los yog duab los qhia yog "txhaj" los yog "ntses" rau ntawm txoj kev sib sau ua ke (hlau net lossis yas net) nyob rau hauv ntub dej ntawm lub tshuab ntawv los ua lub cev qhuav dej. Cov ntawv ntub thiab cov khoom qhuav qhuav yog tag nrho cov hlua khi ncaj nraim. , Thiab dov rau hauv ib lub yob -zoo li daim ntawv.
Qhov txawv: Cov tais ntawv thiab cov duab los qhia siv cov khoom sib txawv thiab ziab. Paper lossis cardboard papermaking tshuab yog feem ntau loj - cov cuab yeej ntsuas uas sib sau ua ke thiab ziab.
