Qhov tseeb ntawm kev sib kis ntawm hydraulic system ntawm lub tshuab nqus tsev nqus tsev nws tus kheej kuj yuav cuam tshuam
Lub tshuab txhaj tshuaj molding tuaj yeem ua tiav qhov kev txhaj tshuaj molding, tab sis thaum cov neeg ua haujlwm siv nws, lawv yuav tsum tau ua tib zoo saib xyuas cov ntsiab lus hauv qab no, txhawm rau ua kom muaj kev nyab xeeb ntawm cov txheej txheem tsim khoom thiab kev nyab xeeb ntawm tus kheej.
Yog tias qhov kub ntawm lub tshuab txhaj tshuaj molding nce, ces tseem muaj ntau yam kev puas tsuaj rau peb nyob rau hauv cov ntaub ntawv no. Piv txwv li, nws tuaj yeem muab qhov teeb meem ntawm deforming lub tshuab. Vim hais tias yog tias cov coefficient ntawm thermal expansion ntawm hydraulic qhov sib txawv, ces nws clearance yuav hloov raws li, yog li yuav muaj qhov system tsis ua hauj lwm, thiab qhov tseeb ntawm hydraulic system tus kheej kis tau tus mob yuav ib txwm muaj feem xyuam rau kev ua hauj lwm zoo ntawm lub tshuab. .
Lub tshuab nqus tsev tsim cov khoom siv yas yog ntxiv rau cov kuab tshuaj rhuab
Ob-xim txhaj tshuaj molding tshuab nyob rau hauv kauj ruam. Cov dej cov ntsiab lus ntawm lub siab polymer aqueous tov tom qab qhov kev rho tawm no yog 30 feem pua rau 40 feem pua , thiab cov xim tsis muaj xim polyvinyl chloride los yog cov tshuaj lom neeg ntawm cov tshuaj muaj pes tsawg leeg tau txais, thiab cov permeate tseem muaj cov kuab tshuaj, cov hlau tsis muaj hlau, thiab lwm yam. Cov kuab tshuaj, tackifiers lossis lwm yam khoom noj khoom haus. Qhov no txhais tau hais tias cov yas yog sib cais los ntawm cov yas-coated ntaub, thiab cov kuab tshuaj thiab cov uas tsis yog-solvent yog muab rho tawm raws li fractional distillation. Ntxiv rau qhov no, polyvinyl chloride yog yaj hauv cov kuab tshuaj. Nws yog siv nyob rau hauv lub circulatory system, thiab dej thiab hnyav yuav tsum yog feem ntau sib tov, thiab cov seem tackifier thiab lwm yam preservatives ces ntxuav nrog ib tug non-solvent mix ob-xim moso xyoob-zoo li tus neeg sawv cev. Lub hom phiaj ntawm kev ntxuav, lwm txoj kev tau txais ntawm cov txheej txheem ntau lawm, thiab tom qab ntawd ua PVC khom tawm. Ntxiv cov yas trim rau cov kuab tshuaj rhuab.
Lub tshuab nqus tsev sib sau tshuab kais dej ua tsis yog qhov hnyav
Txoj kev no ua rau kom tau txais cov ntshiab polymers thiab preservatives, thiab muaj ib txoj hauv kev zoo sib xws. Thaum tshav kub kub, kais dej yog siv los ua ib qho uas tsis yog-solvent. Kev sib koom ua ke ntawm cov tsis muaj kuab tshuaj rau hauv cov tshuaj aqueous tsis yooj yim tsim cov azeotrope. Qhov no feem ntau yog ntsug nyias zaj duab xis evaporator.
