Lub tshuab nqus tsev ntim yog tshem tawm cov huab cua hauv lub hnab ntim khoom thiab ntim cov ntaub ntawv kom ua tiav lub hom phiaj ntawm kev khaws cia tshiab thiab khaws cia ntev ntev ntawm cov khoom ntim, uas yooj yim rau kev thauj mus los thiab khaws cia.Lub tshuab nqus tsev ntim khoom yog lub tshuab uas tom qab muab cov khoom tso rau hauv lub thawv ntim khoom, nqus cov cua hauv lub thawv, ncav cuag qhov ntsuas qhov nqus tau ua ntej (feem ntau nyob ib puag ncig 2000 ~ 2500Pa) thiab ua tiav cov sealing.Nws tseem tuaj yeem ntim nrog nitrogen lossis lwm cov roj sib xyaw, thiab tom qab ntawd ua tiav cov txheej txheem sib khi.
Txij li xyoo 1940, lub tshuab nqus tsev ntim tshuab tau tshwm sim thiab tau siv.Txog thaum nruab nrab mus txog rau 50 xyoo, lub tshuab nqus tsev ntim teb maj mam pib siv polyethylene thiab lwm yam yas zaj duab xis rau ntim.Nyob rau hauv thaum ntxov 1980s, nrog kev loj hlob sai ntawm cov khw muag khoom lag luam thiab maj mam nce qib ntawm cov ntim me me, cov cuab yeej siv thiab tsim.Lub tshuab nqus tsev ntim yog tsim rau ntau lub hnab ntim cov hnab yas los yog cov hnab ntim aluminium ntawv ci, xws li polyester / polyethylene, nylon / polyethylene, polypropylene / polyethylene, polyester / aluminium ntawv ci / polyethylene, nylon / aluminium ntawv ci / polyethylene, thiab lwm yam.Nrog rau kev txhim kho txuas ntxiv ntawm tib neeg txoj kev paub txog kev xav, kev siv lub tshuab nqus tsev ntim khoom tau nyiam ntau thiab ntau dua los ntawm kev lag luam xws li zaub mov, textiles, thiab electronics.
Lub hauv paus ntsiab lus thiab kev faib tawm ntawm cov khoom siv nqus tsev vacuum
Cov qauv ntawm lub tshuab nqus tsev ntim khoom sib txawv, thiab cov txheej txheem kev faib tawm kuj txawv.Feem ntau raws li kev ntim khoom sib txawv, nws tuaj yeem muab faib ua cov tshuab extrusion, hom intubation, hom chamber, thiab lwm yam;Raws li txoj kev cov khoom ntim nkag mus rau hauv lub chamber, nws tuaj yeem muab faib ua ib lub chamber, ob chav chamber, thermoforming hom, conveyor siv hom, thiab teb lub tshuab nqus tsev chamber.Raws li hom kev txav, nws tuaj yeem muab faib ua ntu ntu thiab txuas ntxiv;Raws li kev sib raug zoo ntawm cov khoom ntim khoom thiab lub thawv ntim khoom, nws tuaj yeem muab faib ua lub tshuab nqus tsev ntim khoom thiab lub tshuab nqus tsev nqus ntim.
Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm tib neeg txoj kev ua neej nyob, daim ntawv thov ntawm lub tshuab nqus tsev ntim tshuab yuav dhau los ua ntau dua, thiab ntau yam, style, kev ua tau zoo, thiab qhov zoo ntawm cov khoom ntim khoom nqus tsev yuav hloov thiab txhim kho.Hauv kev lag luam textile thiab handicraft, lub tshuab nqus tsev ntim tuaj yeem txo qhov ntim ntawm cov khoom zoo thiab pab txhawb kev ntim khoom thiab kev thauj mus los;nyob rau hauv kev lag luam khoom noj khoom haus, lub tshuab nqus tsev ntim thiab ua kom tsis muaj menyuam tuaj yeem cuam tshuam cov kab mob loj hlob, ua rau cov zaub mov tsis zoo, thiab ua kom lub txee lub neej ntawm cov zaub mov;Hauv cov khoom siv hluav taws xob, Hauv kev lag luam kho vajtse, lub tshuab nqus tsev ntim khoom siv tuaj yeem cais cov pa oxygen, kom cov khoom siv yuav tsis oxidize thiab xeb.
