Txoj kev loj hlob ntawm HPMC technology thiab txheej txheem ntawm hydroxypropyl methyl cellulose nyob rau hauv Suav teb

Hydroxypropyl methyl celluloseHPMCmus rau tam sim no domestic ntau lawm yog muab qhov tseem ceeb rau cov kua theem txheej txheem technology, cov cuab yeej no yog sawv cev los ntawm wuxi tshuaj kev lag luam kev tshawb fawb thiab tsim lub koom haum nyob rau hauv Tuam Tshoj kev tshawb fawb chav tsev nyob rau hauv 1970s, kev tshawb fawb ua tau zoo nyob rau hauv lub hauv paus ntawm kev nce qib, tus thawj yog cov roj theem txoj kev etherification cov tshuaj tiv thaiv, vim hais tias cov cuab yeej tsis hloov mus rau peb lub teb chaws, ces ua hauj lwm tawm cov kua theem txheej txheem etherification cov tshuaj tiv thaiv theem tseem ceeb ntawm cov txheej txheem dej ntau lawm. qee qhov paub zoo cellulose ether manufacturers.

Hauv tsev hydroxypropyl methyl cellulose HPMC ntau lawm feem ntau siv cov paj rwb ua kom zoo li cov khoom siv raw (qee lub tuam txhab kuj tau pib sim siv ntoo pulp), thiab kev sib tsoo hauv tsev los yog siv ncaj qha siv cov paj rwb refined alkalization, etherification siv binary tov organic hnyav, cov tshuaj tiv thaiv nyob rau hauv ntsug reactor. Cov txheej txheem purification siv cov txheej txheem tsis sib xws uas cov kuab tshuaj organic raug tshem tawm hauv lub reactor thiab cov khoom nyoos yog purified los ntawm ob peb ntxuav thiab lub cev qhuav dej los ntawm scrubbers thiab centrifuges. Cov khoom tiav tiav nrog kev sib tshuam granulation, nyob rau hauv cov cua sov (tseem muaj cov chaw tsim khoom tsis muaj granulation), ziab thiab crushing raws li cov qauv, feem ntau ntawm cov kev ua tshwj xeeb tsuas yog ncua sij hawm hydration lub sij hawm ntawm cov khoom (yuam qhuav yaj) ua yam tsis muaj mildew tiv thaiv thiab faib ua, ntim siv phau ntawv.

Cov txheej txheem ua kua theem muaj qhov zoo hauv qab no: cov txheej txheem cov tshuaj tiv thaiv cov khoom siv sab hauv siab me me, cov cuab yeej siv siab muaj peev xwm tsawg, muaj kev pheej hmoo me me; Tom qab impregnation nyob rau hauv lye,cellulosetuaj yeem nthuav dav thiab sib npaug alkalized. Lye tau zoo dua infiltration thiab o ntawm cellulose. Lub etherification reactor yog me me, ua ke nrog lub teeb o ntawm alkali cellulose, yog li qhov zoo ntawm cov khoom yog yooj yim los tswj, hloov qib thiab viscosity tuaj yeem tau txais cov khoom zoo sib xws, ntau yam kuj hloov tau yooj yim.

Txawm li cas los xij, cov txheej txheem no kuj muaj qhov tsis zoo hauv qab no: lub reactor feem ntau tsis loj heev, cov kev txwv kev txheeb cais ua rau muaj peev xwm tsim tau me me, txhawm rau txhim kho cov khoom tsim tawm, nws yog ib qho tsim nyog yuav tsum tau nce cov reactors; Refined thiab purified crude khoom xav tau cov cuab yeej siv ntau dua, kev ua haujlwm nyuaj, kev siv zog ua haujlwm; Vim tias tsis muaj kev tiv thaiv kab mob thiab kev kho mob sib xyaw, ua rau cov khoom lag luam viscosity ruaj khov thiab cov nqi tsim khoom raug cuam tshuam; Ntim los ntawm kev siv phau ntawv, kev siv zog, kev ua haujlwm siab; Lub automation degree ntawm kev tswj cov tshuaj tiv thaiv yog qis dua li ntawm cov txheej txheem roj, yog li kev tswj qhov tseeb yog qhov tsawg. Piv nrog rau cov txheej txheem roj, cov txheej txheem hnyav hnyav yuav tsum tau ua.

Nrog kev txhim kho ntawm domestic hydroxypropyl methyl celluloseHPMCntau lawm technology, qee lub lag luam los ntawm kev nruam kev ywj pheej innovation, loj kettle kua theem txoj kev tau tsim los ntawm leaps thiab txhais tau tias, thiab nws muaj nws tus kheej technical yam ntxwv. Anxin chemistry siv tus thawj HPMC cov txheej txheem tsim khoom, tsis yog tsuas yog cov txheej txheem tsim khoom tsim nyog, kev tswj xyuas kev ua haujlwm yog qhov tseeb thiab txhim khu kev qha, kev siv tag nrho thiab tsim nyog ntawm cov khoom siv raw thiab lwm yam ntxwv, thiab cov khoom hloov qib yog sib xws, cov tshuaj tiv thaiv yog tag nrho, cov kev daws teeb meem yog qhov zoo, thiab tib lub sijhawm los xyuas kom meej qhov ruaj khov ntawm cov khoom zoo. HPMC cov kab ntau lawm ntawm qee lub lag luam tau hloov pauv hloov pauv, kom ua tiav cov cuab yeej DCS automation tswj cov cai, cov ntaub ntawv suav nrog cov kua, cov khoom siv raw tuaj yeem siv los ntsuas kom raug thiab ntxiv DCS system, kub thiab siab tswj hauv cov txheej txheem tshuaj tiv thaiv yog txhua yam paub txog DCS tsis siv neeg tswj thiab kev saib xyuas tej thaj chaw deb, Hais txog qhov ua tau, kev cia siab, kev ruaj ntseg thiab kev nyab xeeb ntawm kev tsim khoom, piv rau tib neeg kev ua haujlwm, tsuas yog kev ua haujlwm zoo dua qub. kev siv zog, tab sis kuj txhim kho kev ua haujlwm ib puag ncig ntawm qhov chaw.
