Kev tshuaj xyuas qhov zoo ntawm cov ntawv pulp molding tableware rau cov khoom siv pov tseg uas lwj tau
Txij li xyoo 1984 hauv Suav teb thawj zaug, polystyrene (eps ua cov khoom siv tseem ceeb ntawm cov khoom siv ua npuas yas tableware kis tau sai hauv txhua lub tebchaws, mus rau hauv lub neej txhua hnub ntawm tib neeg, tsim kev lag luam loj heev. Raws li cov ntaub ntawv txheeb cais, Suav teb siv li 10 billion cov khoom siv noj mov ceev ceev txhua xyoo, feem ntau ntawm cov khoom siv yas foamed pov tseg, thiab tus nqi loj hlob txhua xyoo yog 25 feem pua

Vim tias polystyrene tsis lwj, nws nyuaj rau rov ua dua tshiab thiab lwm yam, uas ua rau muaj kev tsis yooj yim rau kev ua haujlwm. Tom qab ntau xyoo ntawm kev ua haujlwm hnyav, kev tsim khoom siv thev naus laus zis, thev naus laus zis thiab cov khoom siv rau cov khoom siv pov tseg pulp pwm thiab zaub mov thiab dej haus tau tsim kho sai hauv peb lub tebchaws. Txhua yam khoom siv rooj tog xav tau rau cov zaub mov txias thiab kub thiab dej haus xws li lub thawv zaub mov ceev ceev. phaj, tais, tais ntau qhov loj me tau tsim: Muaj ntau yam khoom noj txom ncauj, tais zaub, tais diav, thiab lwm yam. Hauv kev ua yeeb yam, cov khw muag khoom loj hauv Asmeskas tau ua tau raws li cov cwj pwm noj mov Suav, tuaj yeem hnav khaub ncaws hauv cov roj kua zaub kub thiab dej tsis muaj kev xau.

Txij thaum ntawd los, kev lag luam pulp molding nrog nws lub zog ntawm kev tiv thaiv ib puag ncig hauv thaj av ntawm Tuam Tshoj tau loj hlob sai thiab nthuav dav. txog rau xyoo 1990s pib nthuav dav. Kev lag luam. Tam sim no, cov ntawv pulp molding los ntawm cov thawv zoo rau ib puag ncig!

A, cov khoom siv ua kom cov khoom siv zom zaub mov tsis zoo
Nrog cov nplej straw, qab zib, reed, straw thiab lwm yam nroj tsuag txhua xyoo uas ua los ntawm cov pulp los ntawm kev sib tsoo pulp, grouting (lossis nqus, dredoing), shaping, shaping (lossis shaping) txiav, xaiv, tua kab mob, ntim, thiab lwm yam, Cov khoom siv raw siv yog rov ua dua tshiab thiab rov ua dua tshiab, thiab tsis muaj dej dub lossis dej khib nyiab los ntawm txoj kev pulping lub cev.

Qhov zoo ntawm cov khoom siv pulp molding:
(1) Cov khoom siv raw yog cov pulp pov tseg lossis cov nplej rov ua dua tshiab, reed, straw, xyoob, qab zib pas nrig, xibtes thiab lwm yam straw fibers. Qhov chaw dav, tus nqi qis, thiab tsis siv ntoo.
(2) Tsis muaj dej khib nyiab tsim tawm lossis tso tawm hauv cov txheej txheem ntau lawm, Cov thawv ntim khoom zoo los ntawm xwm
(3) Cov khoom no tsis muaj dej thiab roj pov thawj
(4) Thaum siv, tuaj yeem khov, khov, qhov cub microwave cua sov, tuaj yeem ci 220 degrees
(5) Cov khoom no tuaj yeem lwj tag nrho hauv lub xeev ntuj hauv 45-90 hnub, thiab tuaj yeem ua compost hauv tsev. Tom qab lwj tag, cov khoom tseem ceeb yog cov khoom siv organic uas yuav tsis tsim cov khib nyiab thiab cov pa phem.
(6) Ua ib lub thawv ntim khoom, nws muaj cov yam ntxwv ntawm kev sib xyaw, kev tiv thaiv kev sib xyaw thiab kev poob siab uas tuaj yeem tiv thaiv cov khoom ntim khoom tau zoo
(7) Cov khoom siv hluav taws xob ntim khoom yuav tsis tsim hluav taws xob zoo li qub
