Qhov sib txawv ntawm ib lub ntsia hlau thiab ob lub ntsia hlau extruder

Ib lub tshuab extruder ntsia hlau: tsim rau ib yam khoom thiab cov tsiaj txhu thiab nqaij qaib sib koom ua ke pub.

Lub tshuab extruder ntxaib ntsia hlau: feem ntau yog siv rau hauv kev tsim cov khoom noj hauv dej thiab tsiaj txhu uas muaj nqis ntxiv, xws li ntses eel, vaub kib, thiab ntses menyuam yaus, vim tias tus nqi ntawm cov khoom no muag hauv khw txaus los them rov qab tus nqi ntawm kev tsim khoom siv cov thev naus laus zis ntxaib ntsia hlau; Tsis tas li ntawd, qee cov khoom noj hauv dej tshwj xeeb, xws li cov khoom noj hauv dej me me (nrog lub cheeb ntawm 0.8 ~ 1.5 hli), cov khoom noj hauv dej muaj roj ntau, thiab cov khoom noj uas muaj cov khoom me me tab sis hloov pauv tas li, kuj yuav tsum tau tsim los ntawm kev siv lub tshuab extruder ntxaib ntsia hlau.

Yuav tsum tau piav qhia meej tias qhov sib txawv saum toj no tsis paub meej. Piv txwv li, peb xav kom siv cov ntsia hlau ob lub los tsim cov khoom noj hauv dej, tab sis tam sim no ntau lub tuam txhab siv cov ntsia hlau ib lub los tsim cov khoom noj hauv dej. Muaj qhov sib txawv ntawm kev siv ob lub rau cov khoom noj hauv dej. Hauv ntej, piv rau cov ntsia hlau ib lub, ob lub ntsia hlau muaj cov txiaj ntsig hauv qab no:

① Qhov kev hloov pauv ntawm cov khoom siv raw yog dav dua, uas tuaj yeem hloov kho rau kev ua cov viscosity siab, viscosity qis, cov roj ntau, cov dej noo lossis viscosity siab, oily, cov ntaub ntawv raw ntub heev, thiab lwm yam khoom siv uas yuav plam hauv ib lub ntsia hlau (SSE).

② Muaj tsawg dua kev txwv rau qhov loj me ntawm cov khoom siv raw, uas tuaj yeem hloov kho rau kev ua cov khoom siv raw los ntawm cov hmoov me me mus rau cov hmoov av ntxhib thiab cov ntsia hlau ib leeg ua cov khoom siv nrog cov qhov loj me sab nraum qhov ntau thiab tsawg tshwj xeeb.

③ Cov khoom ntws hauv lub thoob zoo ib yam, thiab cov pa dej, dej, thiab lwm yam tuaj yeem ntxiv rau kom ua tiav cov txiaj ntsig xav tau ntawm cov khoom.

④ Qhov zoo sab hauv thiab sab nraud ntawm cov khoom zoo dua, uas tuaj yeem ua tiav lub xeev zoo sib xws thiab ua rau cov qauv molecular ntawm cov khoom sib npaug. Qhov chaw du thaum lub sijhawm extrusion. Cov khoom me me muaj kev sib xws siab thiab kev sib xws zoo.

⑤ Qhov ua kom siav thiab homogenization zoo dua, feem ntau nrog qib hmoov txhuv nplej siab tshaj 95%, uas ua rau cov khoom noj hauv dej ua tiav kom ruaj khov hauv dej, tiv thaiv kev poob ntawm cov as-ham hauv cov khoom, thiab yooj yim zom thiab nqus tau.

⑥ Cov khoom tsim tau zoo dua nyob rau hauv lub zog sib npaug. Kev sib xyaw ua ke zoo ua rau cov cua sov tau txais raws sijhawm, ua kom cov khoom loj hlob sai dua, txo qhov kub ntawm cov khoom, thiab txhim kho cov khoom tsim tawm.

⑦ Cov khoom muaj ntau yam thiab hloov tau yooj yim dua, thiab nws tuaj yeem ua cov khoom noj me me hauv dej, cov mis roj ntau, cov dej noo ntau, cov khoom lo rau zoo, thiab ntau xim, hom sandwich, thiab cov khoom zoo li tshwj xeeb.

⑧ Kev ua haujlwm ntawm cov txheej txheem yooj yim dua, thiab qhov ceev ntawm lub spindle tuaj yeem hloov kho raws li qhov xav tau ntawm cov khoom ua tiav. Vim yog qhov ua kom huv nws tus kheej, kev ntxuav yooj yim heev, thiab tsis tas yuav tsum rhuav cov khoom siv tom qab txhua qhov kev ua tiav.

⑨ Cov khoom tsis muaj zog hnav tsawg dua. Ib qho kev nkag siab yuam kev yog tias ib lub ntsia hlau muaj kev hnav tsawg dua. Qhov tseeb, thaum lub sijhawm txheej txheem extrusion ntawm ob lub ntsia hlau, vim yog kev thauj khoom ruaj khov thiab cov yam ntxwv ntawm cov khoom ntws, qhov hnav ntawm cov khoom ntawm lub ntsia hlau thiab lub tes tsho sab hauv ntawm lub thoob yog me dua li ntawm ib lub ntsia hlau. Txawm hais tias tus lej ntawm cov ntsia hlau yog ib qho ntxiv, tus nqi ntawm cov khoom siv tseem qis dua li ntawm ib lub ntsia hlau.

⑩ Tus nqi tsim khoom qis dua. Vim yog qhov ruaj khov ua haujlwm zoo ntawm tus qauv ntsia hlau ntxaib, muaj tsawg dua tus nqi pib, tsawg dua dej thiab roj pov tseg, tsawg dua tus nqi ua haujlwm, kev ua haujlwm hloov pauv cua sov siab, cov txiaj ntsig siab, thiab cov cim qhia hluav taws xob siab hauv cov txheej txheem ua khoom noj. Tsis tas li ntawd, tus nqi ntawm cov khoom siv kuj qis, thiab tus nqi tsim khoom kawg tseem qis dua piv rau ib lub ntsia hlau.

Vim yog muaj ntau yam zoo ntawm cov ntsia hlau ntxaib piv rau cov ntsia hlau ib leeg hauv kev tsim cov khoom noj hauv dej peb thiaj li txhawb kom xaiv cov ntsia hlau ntxaib thaum muaj xwm txheej tso cai rau txhua yam.

Cov kev ceev faj nram qab no yuav tsum tau ua thaum siv lub twin screw extruder:

1. Kev nyab xeeb ntawm kev ua haujlwm:

-Ua ntej siv lub tshuab extruder ntxaib, nws yog ib qho tsim nyog yuav tsum paub txog cov txheej txheem ua haujlwm ntawm cov khoom siv, kev ceev faj txog kev nyab xeeb, thiab kev siv cov khoom siv kaw thaum muaj xwm txheej ceev.

-Cov neeg teb xov tooj yuav tsum hnav cov khoom siv tiv thaiv kom tsis txhob muaj xwm txheej thiab raug mob thaum lub sijhawm ua haujlwm.

-Xyuas kom muaj kev nyab xeeb ntawm qhov chaw ua haujlwm nyob ib puag ncig cov khoom siv thiab tiv thaiv kev raug mob xws li kev plam thiab kev sib tsoo.

2. Kev saib xyuas cov khoom siv:

-Tsis tu ncua saib xyuas thiab tswj lub twin screw extruder, suav nrog kev ntxuav, lubrication, tightening bolts, thiab lwm yam. Xyuas kom meej tias cov khoom siv ua haujlwm zoo.

- Tshawb xyuas cov khoom uas yooj yim hnav xws li cov ntsia hlau, cov ntaub txuas, thiab cov khoom sib dhos, thiab hloov lawv raws sijhawm kom ntseeg tau tias cov khoom siv ua haujlwm ib txwm.

-Tsim cov phiaj xwm txij nkawm raws li qhov zaus ntawm kev siv cov khoom siv thiab qhov chaw ua haujlwm kom ntseeg tau tias cov khoom siv ua haujlwm ruaj khov mus ntev.

3. Kev hloov kho tau ntawm cov ntaub ntawv raw:

-Cov tshuab ua kom lub hau ntswj ob lub tshuab muaj qhov xav tau siab rau cov khoom siv raw, thiab cov khoom siv raw sib txawv yuav xav tau cov txheej txheem puffing sib txawv thiab cov txheej txheem ua haujlwm.

-Thaum xaiv cov khoom siv, nws yog qhov tsim nyog los xyuas kom meej tias tus qauv thiab cov lus qhia ntawm cov khoom siv yog qhov tsim nyog rau cov txheej txheem ua tiav raws li cov yam ntxwv ntawm cov khoom siv raw thiab cov kev cai ua tiav.

4. Kev tswj kub thiab ceev:

-Qhov kub thiab qhov ceev tig yog cov yam ntxwv tseem ceeb uas cuam tshuam rau cov txiaj ntsig ua tiav ntawm cov ntsia hlau ntxaib extruder, thiab lawv xav tau kev hloov kho thiab kev tswj hwm tsim nyog.

-Kev tswj qhov kub thiab txias yuav tsum tau kho raws li cov khoom siv raw thiab cov kev cai ua tiav sib txawv. Qhov kub thiab txias ntau dhau yuav ua rau cov khoom siv raw loj dhau lossis hlawv, cuam tshuam rau qhov zoo ntawm cov khoom.

-Kev tswj qhov ceev ntawm kev sib hloov kuj yuav tsum tau hloov kho kom haum raws li cov khoom siv raw thiab cov kev cai ua haujlwm. Kev sib hloov ceev siab lossis qis yuav cuam tshuam rau cov txiaj ntsig ntawm kev ua haujlwm thiab qhov zoo ntawm cov khoom.

5. Cov khoom siv ntau npaum li cas thiab kev tswj cov txheej txheem:

-Kev tswj cov khoom siv yuav tsum tau hloov kho raws li cov lus qhia ntawm cov khoom siv thiab cov yam ntxwv ntawm cov khoom siv raw. Cov khoom siv ntau dhau yuav ua rau cov khoom siv thaiv, thaum cov khoom siv tsawg dhau yuav ua rau kev ua haujlwm tsis zoo.

-Kev tswj cov txheej txheem yuav tsum tau muaj kev npaj tsim nyog ntawm kev pub mis thiab kev tso tawm ntawm cov khoom siv raw, xyuas kom meej tias cov khoom siv raw sib npaug thiab kev tso tawm ntawm cov zis, thiab zam kev thaiv thiab kev sib tov.

6. Kev ntxuav thiab kev tu cev:

-Thaum siv lub tshuab extruder ntxaib, yuav tsum tau them sai sai rau kev huv thiab kev tswj hwm kev huv ntawm cov khoom siv, thiab yuav tsum tau ntxuav cov seem thiab hmoov av hauv cov khoom siv kom tiv thaiv kev kis kab mob thiab kev loj hlob ntawm cov kab mob.
