1. Pulp thiab ntawv tais molding ntub nias txheej txheem
Cov txheej txheem ntub dej yog hais txog cov txheej txheem ntawm kev txhaj tshuaj slurry rau hauv molding tuag los ntawm cov raj xa dej tom qab pulping, adsorbing cov dej ntau dhau los ntawm lub tshuab nqus tsev, tsim cov embryo ntub thiab tam sim ntawd hloov mus rau kub nias molding tuag kom ceev extrusion ziab;
Qhov zoo ntawm cov txheej txheem ntub dej: Cov khoom siv tiv thaiv ib puag ncig uas tsim los ntawm cov txheej txheem ntub dej muaj kev ua haujlwm siab, thiab raug xa mus rau qhov kawg cov duab tam sim tom qab tsim, thiab cov khoom siv ceev ceev; cov dej noo ntawm cov embryo ntub dej hauv cov txheej txheem ntub dej yog li 65-75%, cov ntsiab lus noo noo yog siab, thiab lub tshuab nqus tsev adsorption yuav tsum tau siv sijhawm ntev; Cov khoom lag luam degradable tableware uas tsim los ntawm cov txheej txheem ntub dej ntub dej muaj qhov du thiab muag, zoo nkauj thiab zoo nkauj; Cov thawv ntim khoom noj uas tau muab pov tseg uas tsim los ntawm cov txheej txheem ntub dej muaj cov phab ntsa tuab dua, qhov ntom ntom dua thiab txuag ntim;
Qhov tsis zoo ntawm cov txheej txheem ntub dej: nws tsis yooj yim rau kev tsim los yog demold cov khoom noj su uas siv tau nrog txoj kab nqes me me; cov khoom uas muaj R lub kaum sab xis me me los yog txoj kab nqes me me muaj qhov tawg ntau dua; kev siv hluav taws xob kub yog qhov loj.
Daim ntawv thov teb ntawm ntub pressed ntawv tais tshuab:
1. High-cov hnab ua haujlwm zoo, tseem hu ua qib siab- ntawv qib- cov hnab yas ua haujlwm, feem ntau yog cov khoom molded nrog du thiab zoo nkauj sab nraud tsim los ntawm ntub compression molding. Cov khoom no feem ntau haum rau high-kawg hauv ob sab phlu thawv, siab-kawg razor ntim thawv, High-kawg khaub ncaws ntim thawv, iav thawv, thiab lwm yam. Cov khoom no yuav tsum tau muaj siab precision, zoo nkauj tsos, thiab siab dua tus nqi ntxiv dua lwm yam ntub dej- nias cov khoom.
Txhawm rau kom zoo nkauj dua thiab txhim kho tus nqi ntxiv ntawm cov khoom ntim, cov khoom zoo li no kuj tuaj yeem luam tawm xim kom pom cov nyhuv ntawm cov ntim zoo dua.
2. Cov thawv ntim khoom noj, tseem hu ua degradable tableware, feem ntau yog xa mus rau ntub- cov khoom siv molded xws li phaj, tais, thawv, ncuav mog qab zib tais, thiab lwm yam uas tuav cov zaub mov, feem ntau ua los ntawm cov ntoo fibers xws li nplej straw, qab zib, thiab lwm yam. Ua kom tiav, ntxiv zaub mov - qib waterproof thiab roj{5}.
Nws tuaj yeem siv rau hauv kev noj zaub mov txhua hnub, noj hmo hauv tsev so-hauv, nqa- tawm thiab xa khoom, thiab lwm yam. Cov khoom lag luam no xav tau cov kab mob thiab cov hlau hnyav kom ua tau raws li cov khoom noj - qib yuav tsum tau ua. Nws yog tsim nyob rau hauv plua plav-rhiav dawb thiab muaj qhov huv thiab zoo nkauj.
3. Cov tais ntawv kho mob, feem ntau yog ntub dej - cov khoom siv nias, feem ntau yog siv rau kev sib tsoo ntawm cov khoom siv thiab tshuaj, thiab lwm yam, thiab yuav tsum muaj plua plav- kev tsim khoom pub dawb, cov kab mob yuav tsum tau tswj raws li cov qauv kev kho mob, thiab plua plav- pub dawb lub tshuab nqus tsev vacuum.
4. Cov khoom ua si lom zem hais txog lub qhov ncauj qhov ntswg, cov khoom ua si xim, thiab lwm yam, uas tuaj yeem tsim tau los ntawm semi- nias qhuav thiab ntub dej. Nws yuav tsum tau zoo deg smoothness thiab tuaj yeem khaws cov xim pleev xim zoo, ua rau tes zoo dua thiab du . .
2. Ntawv pulp molding qhuav nias txheej txheem
Cov txheej txheem ziab qhuav txhais tau hais tias tom qab pulping, slurry yog txhaj rau hauv cov pwm pwm los ntawm cov kav dej, thiab tom qab lub tshuab nqus tsev adsorption ntawm cov dej ntau dhau los tsim cov embryo ntub dej, cov dej noo ntawm cov embryo ntub yog txo kom txog li 40% los ntawm ntuj ziab los yog los ntawm kev ziab tshwj xeeb, thiab tom qab ntawd cov txheej txheem yog nqa tawm. Cov txheej txheem ntawm shaping thiab molding, uas feem ntau yog siv los tsim cov qe qe qe qis qis, cov hnab pulp thiab lwm yam khoom.
Qhov zoo: tsawg dua kev siv hluav taws xob thiab kev siv hluav taws xob tsawg; feem ntau cov khoom siv pulp, cov ntawv pov tseg tuaj yeem rov ua dua tshiab, tus nqi qis thiab tus nqi qis; thicker khoom thickness, zoo poob siab kuj thiab compression nyhuv; ntim cov khoom siv hluav taws xob tuaj yeem tiv thaiv hluav taws xob zoo li qub;
Qhov tsis zoo: qhuav- cov khoom nias (xws li semi- qhuav- nias) cov khoom muaj qhov ntxhib ntxhib thiab tsis zoo nkauj; phab ntsa thickness yog thicker, accounting rau ib tug loj ntim;
Qhuav nias txheej txheem thov teb:
1. Cov hnab ua haujlwm ib txwm siv feem ntau yog xa mus rau cov hnab ntim khoom, cov tais qe, cov tais txiv hmab txiv ntoo thiab lwm yam khoom ntawm cov khoom siv hluav taws xob qis qis uas tsim los ntawm cov txheej txheem qhuav ntawm cov tawv nqaij daj.
2. Kev ntim khoom ua liaj ua teb feem ntau yog hais txog paj lauj kaub, lub khob ntim, qe tais, thiab lwm yam. Feem ntau ntawm cov khoom no yog tsim los ntawm cov txheej txheem qhuav ntawm cov tawv nqaij daj thiab cov ntawv xov xwm. Cov khoom no muaj cov kev xav tau tsawg rau kev nyiam huv thiab cov khoom nruj. Tsis siab, tab sis yuav tsum tau ua kom zoo dua dej tsis zoo.
3. Kev ntim khoom kho mob, cov xovxwm qhuav yog siv rau hauv qhov chaw uas tsis tshua muaj kev xav tau xws li txaj txaj, tso zis, raum- cov tais zoo li, thiab lwm yam.
