Xaiv lub nruas flaker rau stearic acid ntau lawm yuav tsum sib piv lub tshuab rau stearic acid cov khoom (tsis tshua muaj melting point ~ 69-72 degree, nruab nrab viscosity, nyiam lo) thiab koj cov khoom teev, cov khoom specifications, thiab kev khiav hauj lwm tej yam kev mob. Hauv qab no yog ib daim ntawv qhia txog kev xaiv tseem ceeb.
1. Nkag siab Stearic Acid's Key Properties
Stearic acid yog fatty acid nrog:
* Melting point: ~ 69-72℃(tsawg, yooj yim rau solidify ntawm lub nruas txias)
* Viscosity: nruab nrab thaum molten (feem ntau<500 cP at 80–90°C)
* Adhesion: nyiam lo rau cov hlau nto; xav tau kev tso tawm zoo
* purity: qib zaub mov/pharma xav tau kev huv huv; cov qib kev lag luam tsis tshua nruj
* Thermal rhiab heev: me me; tsis txhob overheating kom tsis txhob muaj xim
2. Tshuab Hom & Configuration
Ib leeg vs. Ob Nruas
* Ib lub nruas flaker (feem ntau rau stearic acid)
Yooj yim, tus nqi qis dua, yooj yim los ntxuav
Txaus rau stearic acid ceev ceev solidification
Xaiv lub peev xwm txog li ~ 15 t / h
* Ob chav nruas flaker
Kev hloov hluav taws xob ntau dua; siv rau cov yeeb yaj kiab loj heev lossis cov yeeb yaj kiab tuab
Higher investment; only needed for >15 t / h lossis qib tshwj xeeb
Hom Enclosure
* Qhib hom: rau cov qauv kev lag luam stearic acid; tus nqi qis dua
* Semi-kaw / kaw tag nrho: rau qib zaub mov / chaw muag tshuaj, tswj plua plav, lossis pam nitrogen (tiv thaiv oxidation)
3. Nruas Specifications
Khoom siv ntawm kev tsim kho
* Nruas plhaub: 304 lossis 316L stainless hlau(khoom noj / khoom noj) lossis carbon hlau (kev lag luam)
Polished tiav (Ra Tsawg dua los yog sib npaug rau 0.8 μm) kom txo tau cov nplaum thiab txhim kho flake tso tawm
* Sab hauv cua txias channel: kauv baffles lossis radial ribs kom txias txias
Nruas Loj (Txiav txim siab muaj peev xwm)
* Txoj kab uas hla:800-1800 mm (tus qauv rau stearic acid)
* Ntev:1000-3000 hli
* Thaum tshav kub kub hloov chaw:2-20 m² (nrog rau koj lub hom phiaj t / h)
Txoj cai ntawm tus ntiv tes xoo: ~ 0.8-1.2 t / h ib m² rau stearic acid
Nruas Ceev & Tswj
* Variable zaus tsav (VFD):0.3-15 rpm (ntev)
Kho ceev kom tswj flake thickness (0.3-1.0 hli rau stearic acid)
Tsawg ceev=thicker flakes; nrawm dua=thinner, ntau dua qub flakes
4. Pub System
Stearic acid xav tau ib tug ruaj khov, zoo li molten zaj duab xis ntawm lub nruas. Xaiv:
* Hauv qab dip feed(feem ntau): nruas dips mus rau hauv ib lub rhuab feed trough
Trough yuav tsum yog lub tsho-rhuab (steam/thermal oil) kom stearic acid molten
* Applicator yob pub: rau cov yeeb yaj kiab nyias nyias (siab- qib stearic acid)
* Khoom noj khoom haus: rau siab -viscosity los yog prone-rau- qib degradation
5. Scraper System
Scraper khoom:
* Phosphor bronze / tooj dag: tus qauv rau stearic acid; kev tso tawm zoo, tsis yog -tag nrho
* Stainless hlau: rau cov qib nyuaj lossis siab dua hnav
* Nylon / polymer: rau zaub mov / chaw muag tshuaj kom tsis txhob muaj kab mob hlau
Scraper tsim:
* Pneumatic / caij nplooj ntoos hlav-loaded: tsis sib xws siab thoob lub nruas ntev; kho tau
* Sab scrapers: tiv thaiv kev tsim ntawm lub nruas kawg (tseem ceeb rau stearic acid)
Kev kho riam: sab nraud, cuab yeej - pub dawb rau kev kho sai
6. Cua txias System
* Cua txias nruab nrab:dej txias (20-30 degree) yog tus qauv rau stearic acid
* Txoj kev ua kom txias:
Internal tsho / kauv txias: zoo tshaj plaws; sib xws kub
Txau txias: tus nqi qis; tsis sib xws (tsuas yog rau me me)
* Cua txias peev:xyuas kom ΔT ~ 30-40℃kom muaj zog stearic acid ua ntej khawb
7. Muaj peev xwm & Ntau lawm yuav tsum tau ua
* Target throughput:1-20 t / h (stearic acid ntau yam)
Oversize los ntawm 10-15% rau yav tom ntej expansion lossis chim siab
* Kev ua haujlwm hom:nruam (24/7) lossis batch
* Flake specs:
Thickness: 0.3-1.0 hli (feem ntau)
Uniformity: ± 0.1 hli kam rau ua (tseem ceeb rau kev ua hauv qab)
8. Kev huv huv & khoom siv tau zoo
* Khoom noj khoom haus / qib tshuaj:
Tag nrho 316L SS tiv tauj qhov chaw
Polished nto (Ra tsawg dua lossis sib npaug li 0.8 μm)
CIP- tus phooj ywg tsim (ib qho yooj yim disassembly, tsis muaj ceg tuag)
Ua raws li FDA, GMP, lossis cov qauv zaub mov hauv zos
* Qib Industrial:304 SS lossis carbon steel; tsawg nruj tiav
9. Cov Txheej Txheem Pabcuam
* Pub trough cua sov:jacketed nrog chav / thermal roj kom tswj tau 80-90 degree
* Plua plav collection:rau kaw systems; txo kev nplua thiab txhim kho kev nyab xeeb ntawm chaw ua haujlwm
* Nitrogen daim pam:rau siab - qib purity los tiv thaiv oxidation
* Tswj vaj huam sib luag:VFD, kub sensors, scraper siab gauge, kev ruaj ntseg interlocks
10. Kev Muag Khoom & Kev Pabcuam Kev Xaiv
* Kev paub: xaiv cov chaw muag khoom nrog cov pov thawj pov thawj stearic acid
* Kev sim: thov cov ntaub ntawv sim nrog koj cov stearic acid los xyuas cov flake zoo thiab muaj peev xwm
* Tom qab- muag:
Cov khoom seem muaj (scrapers, seals, bearings)
Hauv -kev cob qhia chaw ua haujlwm thiab kev cob qhia tus neeg ua haujlwm
Warranty (1-2 xyoos yam tsawg kawg nkaus)
Kauj Ruam kawg: Kev sim khoom
Ib txwm ua qhov kev sim sim nrog koj qhov tseeb stearic acid kom paub meej:
* Flake thickness thiab uniformity
* Tshaj tawm tus nqi
* Tso tawm ntawm lub nruas (tsis muaj nplaum)
* Kev siv hluav taws xob
Qhov no ua kom lub tshuab phim koj cov txheej txheem ua ntej yuav tag nrho.
