Pob C: Nws yog lub tackifier ntawm cov txheej uas feem ntau ua los ntawm cellulose dawb los yog daj hmoov hmoov.
Degreasing
Lub workpiece yuav tsum tau degreased yog tias muaj roj rau ntawm qhov chaw.Muaj peb txoj hauv kev ua:
1. Kub kub;
2.Neutral water-base degreasing tus neeg saib xyuas;
3.Organic hnyav xws li methylene chloride.
Derusting
Lub workpiece tsis tuaj yeem coated yog tias muaj xeb lossis burr rau saum npoo.Kev tiv thaiv corrosion ntawm txheej yuav raug cuam tshuam yog tias siv cov kua qaub ntxuav.
Txheej
Lub workpiece afer degreasing thiab tua blasting yuav tsum tau coated los ntawm Dip-Spin txheej los yog Txau Txheej.
Ua ntej cua sov
Lub workpiece tom qab coated yuav tsum tau pre-rhuab kom sai li sai tau ntawm 80 ~ 150 ℃ rau 8 ~ 15 mins kom evaporate.(raws li kev nqus cua sov ntawm workpiece.)
Kho
Lub workpiece tom qab cua sov ua ntej yuav tsum tau kho ntawm 300-340 ℃ rau 20-40 mins.(raws li kev nqus cua sov ntawm workpiece.)
Ntim
Pob A: 16kg / Hlau chim
Pob B: 24KG yas thoob
Pob C: 5.0kg hlau chim
Lub sijhawm lav zoo
Ua ntej compound 6 lub hlis ntawm 20 ℃
Tom qab sib xyaw ua ke 40 hnub ntawm 20 ℃ (Nws tuaj yeem rov ua dua yog tias ntxiv cov txheej tshiab tsis tu ncua.)
Nws yuav tsum khaws cia hauv qab 20 ℃ yog tias tsis siv.
Txheej txheej txheej
Mix Ratio
Pob A: 16.0 kg
Pob B: 24.0 kg (qhov kom muaj nuj nqis tuaj yeem tsim nyog yog tias cov tshuaj tsuag txheej)
Pob C: 0-50 g (raws li qhov sib txawv viscosity xav tau)
Txoj kev sib tov
Ua ntej sib tov, Khaws qhov hnyav A & B rau hauv dej da dej ntawm 25 ± 2 ℃, tom qab ntawd do A kom cov hlau slurry disperse uniformly los ntawm ntau zaus tov khoom, tom qab A yog tag nrho cov sib npaug sib npaug, txo qhov agitating ceev mus rau 60r / min, thiab ntxiv B.
Ntxiv B rau stirring A maj mam.Tam sim no, lub thoob kub yuav nce mus, thaum nws nce mus txog 35 ℃, pib lub tshuab tub yees kom lub thoob qhov kub thiab txias tsis tu ncua ntawm 35 ℃.
Sib tov sib xyaw li 1 ~ 2 teev nrawm tom qab B ntxiv, tom qab ntawd ntxiv C. C yuav tsum tau hmoov yog tias muaj pob.(Lub thoob kub yuav tsum tsis txhob qis dua 30 ℃, txwv tsis pub C yuav tsis yaj txaus .) Tom qab ntawd do 12 teev. tsis tu ncua.
Cov txheej yuav tsum tau lim los ntawm 80 ~ 100 mesh stainless hlau npo ua ntej nchuav rau hauv lub thoob.
Cov cuab yeej ntsuas kub yuav tsum tau nruab nrog lub thoob ntim kom qhov kub ntawm txheej txheej ntawm 22 ± 2 ℃.
(Yog tias temp. siab dhau lawm, cov xim yuav tsum tau deteriorate, thiab viscosity yuav raug cuam tshuam.) Cov txheej yuav tsum tau nplawm ib ncig kom sib npaug.
Ntsuas qhov ntom ntom, PH, Kub, Viscosity thiab Cr6+ cov ntsiab lus ntawm txheej txheej txhua 8 teev yog tias ua haujlwm tsis tu ncua.

Nco ntsoov
Lwm yam tshuaj xws li txhua yam kua qaub, alkali ntsev tsis tuaj yeem muab sib xyaw rau hauv txheej, rau cov no tuaj yeem qhib Zn & Al phaj kom aging txheej.
Tsis txhob irradiation ntawm tshav ntuj thiab ultraviolet rays ntev lub sij hawm thaum ua hauj lwm, txwv tsis pub nws yuav ua rau kom aging los yog polymerization ntawm txheej.
Nws yog ib qho tseem ceeb heev los tswj qhov kub ntawm txheej.Yog tias qhov kub ntawm txheej hloov pauv thaum ua haujlwm, nws yuav cuam tshuam rau viscosity, tom qab ntawd effect lub txheej quatity ntawm workpiece.Yog li kev sib raug zoo ntawm qhov kub thiab txias, viscosity thiab spinning txheej txheem yuav tsum tau tswj kom zoo thaum txheej.
Lub viscosity yuav txawv yog tias txheej txheej txheej txawv.Xaiv cov ntaub ntawv qis yog cov tshuaj tsuag txheej, thiab xaiv cov ntaub ntawv siab yog dip spin txheej.
