Dab tsi yog cov txheej txheem ntawm kev lag luam pulp molding tshuab

Cov txheej txheem ntawm kev lag luam pulp molding tshuab tuaj yeem muab faib ua cov kauj ruam tseem ceeb hauv qab no. Raws li cov lej thiab cov ntaub ntawv cuam tshuam hauv tsab xov xwm siv, kuv yuav muab cov lus piav qhia ntxaws ntxaws rau koj:
1. Kev npaj cov khoom siv raw
Kev sau cov ntawv pov tseg: Sau ntau hom ntawv pov tseg raws li cov ntaub ntawv raw los xyuas kom meej qhov sib txawv thiab ruaj khov ntawm cov ntaub ntawv raw.
Kev kho mob ua ntej: Kev tshuaj xyuas ua ntej thiab tshem tawm impurity ntawm cov ntawv pov tseg kom paub meej cov khoom siv raw.
2. Pulping
Hydraulic Pulping: Siv hydraulic pulp zeb los rhuav tshem cov ntawv pov tseg rau hauv cov tshuaj fiber ntau slurry.
Kev tshem tawm impurity thiab purification: Xaiv, xuab zeb thiab purify lub tawg chemical fiber slurry kom tshem tawm impurities.
Sib Tsoo: Cov tshuaj fibers tau muab faib nruab nrab thiab broomed los ntawm lub tshuab sib tsoo kom txhim khu kev sib raug zoo ntawm cov tshuaj fibers. Cov kauj ruam no yog qhov tseem ceeb tshwj xeeb rau kev tswj cov kev sib tsoo, vim tias qhov kev sib tsoo ncaj qha cuam tshuam rau kev tsim thiab zoo ntawm cov khoom tom ntej.
3. Kev tsim
Kev sib xyaw: Raws li qhov xav tau ntawm cov khoom lag luam, hauv av pulp yog proportioned thiab kho kom ua tiav qhov xav tau molding nyhuv.
Kev tsim cov txheej txheem: Los ntawm kev siv ntau txoj hauv kev xws li slurry extraction thiab grouting, cov ntaub so ntswg qub yog tsim rau hauv cov pwm. Cov txheej txheem slurry extraction cov khoom yog cov sib xws, thaum cov txheej txheem grouting cov khoom zoo ib yam.
4. Nias thiab shaping
Kub nias molding: Siv cov molding kub los pressurize thiab cua sov cov khoom, sai sai tshem tawm noo noo los ntawm cov khoom, thiab tswj nws cov duab thiab loj npaum li cas. Hauv cov kauj ruam no, feem ntau siv cov khoom siv hluav taws xob muaj xws li roj, roj, roj, hluav taws xob lossis chav dej, cov roj kub kub hloov pauv, thiab lwm yam.
5. Ntug trimming thiab shaping
Ntug trimming: Siv lub tshuab txiav ntug kom raug kho cov lus qhia tshwj xeeb thiab cov qauv ntawm cov khoom, thiab txiav cov khoom seem.
Kev phais yas: Kev phais yas ntxiv yog ua rau ntawm cov khoom kom ntseeg tau tias nws cov tsos thiab qhov loj me raws li cov qauv.
6. Qhuav thiab shaping
Kev ziab: Cov khoom yog qhuav los ntawm kev ziab kom ua tiav ib theem ntawm hardness thiab lub zog.
Tsim: Thaum lub sij hawm ziab, cov khoom maj mam tsim nws cov duab kawg.
7. Kev tshuaj xyuas thiab kev khaws cia
Kev tshuaj xyuas: Siv daim ntawv tableware pom lub tshuab kuaj xyuas thiab lwm yam khoom siv los tshuaj xyuas cov khoom thiab xyuas kom cov khoom zoo.
Hnab ntim khoom thiab khaws cia: Hnab thiab khaws cov khoom tsim nyog rau kev siv lossis muag yav tom ntej.
8. Kev tu thiab tu
Kev saib xyuas txhua hnub: Kev tu cov cuab yeej tsis tu ncua, xyuas qhov xoob ntawm cov khoom siv hluav taws xob thiab cov fasteners.
Kev hloov tsis tu ncua: Raws li kev siv cov cuab yeej siv thiab cov chaw tsim khoom pom zoo, hloov cov khoom siv xws li lubricating roj thiab butter tsis tu ncua.
Los ntawm cov kauj ruam saum toj no, cov tshuab pulp molding tshuab tuaj yeem ua tau zoo thiab ruaj khov tsim ntau yam duab thiab cov lus qhia ntawm cov khoom siv pulp molded, ua tau raws li cov kev xav tau ntawm ntau qhov chaw.
