Kuyanika matabwa ndi njira yofunika kwambiri yopititsira patsogolo zinthu zamatabwa komanso zamakina, kuchepetsa kutayika kwa nkhuni, kukonza kagwiritsidwe ntchito ka matabwa ndikuwonetsetsa kuti matabwawo ndi abwino.Panthawi imodzimodziyo, kufunika ndi phindu lachuma la kuyanika nkhuni kumazindikiridwa ndi anthu.
M'zaka 10 zaposachedwa, kukula ndi kukula kwa ntchito zowumitsa matabwa ku China zakula kwambiri, mabizinesi opangira zida zowumitsa matabwa awonjezeka pang'onopang'ono, ndipo magwiridwe antchito owumitsa apita patsogolo pang'onopang'ono.Zotsatirazi zikuwonetsa zotsatira za kafukufuku waukadaulo wowumitsa matabwa ku China m'zaka zaposachedwa, ndikukupangitsani kuti mumvetsetse ukadaulo waposachedwa wowumitsa matabwa.
1. Zipangizo zamakono zoyanika
Kuyanika kokhazikika kumatanthawuza kutenthetsa kwapanjira kwa mpweya ndi mpweya wonyowa wa mumlengalenga monga chowumitsira ndi nthunzi, madzi otentha, mpweya wa ng'anjo kapena mafuta otentha ngati gwero la kutentha.Kuyanika kwa nthunzi wamba kumatenga gawo lotsogola pakuwumitsa nkhuni ku China, zomwe zimapitilira 80%, ndikutsatiridwa ndi kuyanika wamba ndi gasi wang'anjo ndi madzi otentha ngati mphamvu.
Dziko la China lapanga posachedwapa zida zoyatsira gasi (wotchedwanso mpweya wotentha) powotchera zinyalala zamatabwa mung'anjo yoyaka moto yamkuntho.Zimasintha kuchokera ku kutentha kwachindunji kwa mpweya wa ng'anjo kumayambiriro kwa kuyanika kwa mpweya wonyowa mosalunjika ndi mpweya wa ng'anjo.Sizingawononge zinyalala monga utuchi, shavings ndi zinyalala m'mafakitale opangira matabwa, komanso kuchepetsa mtengo woyanika.
2. Kuchepetsa chinyezi ndi kuyanika
Panthawi ya dehumidification ndi kuyanika, mpweya wonyowa umatsekedwa kuzunguliridwa pakati pa dehumidifier ndi chipinda chowumitsa, ndipo chipinda chowumitsa chimachotsedwa ndi firiji ndi kutaya madzi m'thupi.The dehumidifier imabwezeretsanso kutentha komwe kumatulutsidwa ndi kutentha kwa chipinda chowumitsira, kupulumutsa mphamvu.Poyerekeza ndi kuyanika kwa nthunzi, mphamvu yake yopulumutsa mphamvu ndi 40% ~ 70%.Ndi chida chopulumutsa mphamvu.
Kuchita kwa zinthu zina ku China kwafika pamlingo wapadziko lonse lapansi.Mwachitsanzo, RCG mndandanda wa sing'anga kutentha ndi kutentha kwapawiri kutentha gwero dehumidifiers opangidwa ndi Beijing Forestry University apanga zatsopano mu refrigerant subcooling mode, kamangidwe ka kutentha mpope mpweya mpweya dongosolo ndi yachiwiri mpweya wowonjezera mode, zomwe zawonjezera mphamvu yopulumutsa mphamvu ya dehumidifiers. ndi 15% ~ 20% ndikuchepetsa mtengo wopanga ndi 5% ~ 10%.
3. Kuyanika kwadzuwa
Mphamvu ya dzuwa ndi mphamvu yaukhondo komanso yotsika mtengo yongowonjezedwanso.China ndi mayiko ambiri padziko lapansi ndi olemera mu mphamvu ya dzuwa.Komabe, kukula kwa zipinda zowumitsira matabwa pogwiritsa ntchito mphamvu ya dzuwa m'mayiko osiyanasiyana ndizochepa kwambiri.Kuchuluka kwa kuyanika kwa zipinda zowumitsira dzuwa ku China kumatenga pafupifupi 0.2% ya mphamvu zonse zowumitsa za dzikolo.
China yakwanitsa kupanga trcw sing'anga kutentha ndi GRCT kutentha kwa dzuwa kutentha mpope dehumidifier kuphatikiza kuyanika dongosolo.Zotsatira zake pakuwotcha komanso kuyanika mphamvu zafika pamlingo wapamwamba wapadziko lonse wazinthu zofananira.
4. Kuyanika ndi vacuum
Kuyanika matabwa ndi kuumitsa nkhuni mu chidebe chotsekedwa pansi pa mphamvu ya mumlengalenga.Madzi mu nkhuni imathandizira kusamuka kwamadzi pansi pa mphamvu ya kusiyana kwapakati ndi kunja.Pa nthawi yomweyo, chifukwa otsika machulukitsidwe kutentha kwa madzi zingalowe, zingalowe kuyanika akhoza kukwaniritsa mofulumira kuyanika pa kutentha otsika ndi wabwino kuyanika quality.Beijing Forestry University poyamba anakambirana makhalidwe a nkhuni vakuyumu superheated nthunzi kuyanika ndi kutentha ndi kutengerapo misa pansi. vacuum ndi kupsinjika koyipa, ndikusindikiza zolemba zoyenera.
5, Microwave ndi kuyanika pafupipafupi
Ma microwave ndi kuyanika pafupipafupi kumagwiritsa ntchito nkhuni zonyowa ngati dielectric.Pogwiritsa ntchito ma microwave kapena high-frequency electromagnetic field, mamolekyu amadzi mu nkhuni amazungulira.Panthawi imodzimodziyo, chifukwa cha kusinthasintha kwamagetsi kwamagetsi, mamolekyu amadzi amayenda mofulumira kwambiri ndipo nthawi zambiri, kukangana kumatulutsa kutentha, kotero kuti kutentha ndi kuuma nkhuni.
Hebei Shuowei ndi wopanga R & D ndikupanga zida zonse zamakina othamanga kwambiri.Ili ndi gulu lodziwika bwino la R & D, ukadaulo wopanga okhwima, dongosolo labwino kwambiri lowunikira komanso maukonde amphamvu atatha kugulitsa.Pakadali pano, yapanga kukhala wopanga ndikusintha ukadaulo wamankhwala mwachangu, mitundu yambiri yazogulitsa ndikukula kwakukulu pamakampani omwewo ku China.
