Cov txheej txheem ntau lawm ntawm Ntawv Tableware

Daim ntawv tableware yog ib lub tais uas siv tau los ntawm tib neeg siv cov hlau thiab yas, uas yog tsim los ntawm lub tshuab nqus tsev adsorption molding, ziab, thiab kev sib sib zog nqus ntawm cov tawv nqaij los ntawm pwm. Nws cov txheej txheem ntau lawm tuaj yeem muab faib ua ntu hauv qab no:

1. Pulping txheej txheem

Txhawm rau txhim kho lub zog thiab lwm yam khoom ntawm cov ntaub so ntswg, cov ntaub ntawv tseem ceeb thiab cov khoom siv cuam tshuam yuav tsum tau npaj ua ntej, thiab sib xyaw nrog cov ntaub so ntswg nrog qee qhov kev sib tw thiab ib qho kev xav tau los tsim cov ntaub so ntswg cov ntaub so ntswg.

Cov khoom siv tseem ceeb yog feem ntau bleached ntoo pulp, uas tuaj yeem yuav ncaj qha los ntawm cov ntawv tshwj xeeb thiab cov ntawv mills (tsim los ntawm kev ua cov ntoo).

Feem ntau, cov khoom ntawm cov qib lag luam kuj yuav tsum tau siv cov khoom tuaj txawv teb chaws siab -qib ntoo pulp; mid- cov khoom qib tuaj yeem xaiv cov ntoo ntoo zoo tib yam hauv tsev, thiab qib qis - cov khoom lag luam tuaj yeem xaiv cov khoom siv bagasse pulp, straw pulp, xyoob pulp, reed pulp thiab xaiv cov ntawv dawb ntug, thiab lwm yam. luv fiber ntau pulp.

Txhawm rau kom ua tiav kev siv cov khoom siv raw thiab txo cov nqi, ntau hom kev sib txawv tuaj yeem sib tw raws li cov khoom sib txawv. Ntawm lawv, qhov kev txiav txim ntawm ua npuas ncauj pulp thiab hydro-turbine beater ua rau cov fiber ntau sib cais thiab saponify los txhim kho lub peev xwm ntawm nws cov fibers;

Qhov sib ntxiv ntawm cov ntaub ntawv tseem ceeb yog los txhim kho cov av noo tsis kam ntawm cov ntaub so ntswg molding thiab cov dej tsis zoo ntawm cov khoom tiav. Cov ntaub ntawv tshwj xeeb cuam tshuam tuaj yeem muab ntxiv los npaj cov pulp. Thaum kawg, qhov concentration ntawm cov ntaub ntawv qub tuaj yeem hloov kho kab rov tav txog li 2 feem pua, yog li cov ntaub ntawv qub tuaj yeem muab tso rau ntawm cov pwm mesh. Lub cev qhuav dej molding.

2. Moulding txheej txheem

Kev sib sau yog ua kom cov nqaij nyoos rau hauv ib qho duab ntawm ib nrab -cov ntaub so ntswg ntub dej. Uas yog hais tias, lub pulp los ntawm cov txheej txheem pulping yog lub cev qhuav dej ntawm cov pwm hlau los ua tus qauv ntawm cov ntaub ntub dej ntub dej. Qhov no yog cov txheej txheem tseem ceeb hauv kev tsim cov ntawv tais diav. Txog 95 feem pua ​​​​ntawm cov dej hauv cov ntaub so ntswg raug tshem tawm thaum lub sij hawm molding.

Yog li ntawd, cov txheej txheem no plays lub luag hauj lwm txiav txim siab nyob rau hauv cov khoom zoo, lub zog noj, ntau lawm efficiency txhim kho thiab breakage tus nqi.

Qhov zoo ntawm molding nyob ntawm tej yam xws li tshuab molding, molding txoj kev, pwm qauv thiab zoo, thiab puree zoo.

3. Moulding thiab ziab

Cov txheej txheem ntawm kev tshem tawm cov dej uas tsis tau muab tshem tawm ntawm cov ntaub so ntswg cov ntaub ntawv qauv thaum lub sij hawm tsim cov txheej txheem kom txo tau cov nqi ziab thiab lub cev qhuav dej yog hu ua molding. Simultaneous molding tuaj yeem txhim kho lub zog sib txuas ntawm fibers thiab ua kom lub zog ntawm cov ntawv ntub dej pwm.

Kev ziab yog kom sov thiab evaporate lub pulp tableware qauv nrog kev pab los ntawm lub tshav kub ntawm lub preheated sab sauv thiab qis stereotyped ntshiab tooj liab pwm kom tshem tawm cov dej seem tom qab lub pulp tableware qauv yog molded, thiab nyob rau tib lub sij hawm, nws plays lub luag hauj lwm nyob rau hauv ua kom tsis muaj menyuam.

Vim yog lub zog thermal siv loj hauv cov txheej txheem ziab, tus nqi yog kwv yees li 300 npaug ntawm kev tsim thiab lub cev qhuav dej. Yog li ntawd, tag nrho cov txheej txheem ziab yuav tsum tsim nyog tsim kom txuag tau nqi. Nws tau dhau los ua txoj hauv kev tseem ceeb rau cov lag luam pulp tableware los txhim kho lawv cov txiaj ntsig kev lag luam.

4. Shaping thiab trimming

Nyob rau hauv cov txheej txheem no, cov pwm kub yog siv rau compression molding, calendering, thiab tshem tawm cov net marks tshuav los ntawm daim ntawv web forming, thiaj li hais tias lub puab thiab sab nrauv yog du thiab du, thiab qee cov cim thiab cov qauv yuav raug nias raws li cov neeg siv khoom sib txawv. thiab cov kev cai siv.

Nyob rau tib lub sijhawm, cov burrs ntawm ntug ntawm lub cutlery ceev raug txiav tawm, thiab cov indentation uas yooj yim rau folding thiab qhib lub thawv npog yog nias.

5. Qhov zoo ntawm pulp tableware

Pulp tableware yog ua los ntawm cov qab zib bagasse, straw slag thiab lwm yam 100 feem pua ​​​​tsis yog- ntoo cog fibers uas loj hlob hauv ib xyoos thiab ua tiav rau hauv pulp, thiab zaub mov- qib waterproof thiab roj- pov thawj additives yog siv los ntawm siab -tech scientific thiab technological ua, thiaj li hais tias lub pulp ib puag ncig tiv thaiv tableware muaj cov yam ntxwv nram qab no:

1. Kub ua noj ua haus

2. Txuag cov peev txheej thiab tiv thaiv ib puag ncig

3. Rov qab mus rau carbon dioxide thiab dej, rov qab mus rau qhov xwm txheej

The product quality fully conforms to the national standard of the People's Republic of China for the general technology of disposable degradable tableware gb/t18006.1-1999
