Dab tsi yog qhov kev thov ntawm cov tshuaj potassium stearate?

Raws li anionic surfactant, poov tshuaj stearate yog dav siv nyob rau hauv acrylate roj hmab xab npum / sulfur ua ke vulcanization tshuab. Anionic surfactants. Feem ntau hu ua poov tshuaj xab npum los yog xab npum mos, nws yog tsuas yog siv nyob rau hauv cream thiab tshuaj zawv plaub hau, raws li emulsifiers thiab detergents.

Nws muaj emulsification efficiency siab, tab sis yog rhiab heev rau cov dej nyuaj, thiab tuaj yeem tsim cov calcium xab npum nrog dej tawv, uas tuaj yeem deform lossis rhuav tshem cov emulsion. Nws yog calcium-sensitive emulsifier, yog li nws yuav tsum tau them sai sai rau hauv cov txheej txheem ntawm cov tshuaj pleev ib ce.

Potassiumstearate tseem hu ua "potassium octadecate". Dawb crystalline hmoov, du rau qhov kov, tsis muaj xuab zeb zoo, muaj ntxhiab tsw, soluble hauv dej kub lossis cawv, maj mam soluble hauv dej txias, insoluble hauv ether, chloroform, thiab carbon disulfide, tau los ntawm cov tshuaj tiv thaiv neutralization ntawm stearic acid thiab potassium hydroxide. .

Cov tshuaj aqueous muaj zog alkaline rau ob qho tib si litmus thiab phenolphthalein, tab sis cov tshuaj ethanol tsuas yog me ntsis alkaline rau phenolphthalein. Cov tshuaj yog alkaline vim hydrolysis.

1. Kev npaj cov tshuaj tiv thaiv kab mob rau cov zaub mov qib potassium chloride

Txhawm rau kom txo tau cov ntshav siab, nws raug tso cai ntxiv qee cov tshuaj potassium chloride los hloov sodium chloride hauv ntsev. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntawm kev khaws cia thiab kev thauj mus los ntawm cov poov tshuaj chloride, cov dej uas muaj nyob rau hauv cov khoom txhawb kev tawg thiab recrystallization ntawm cov hmoov av, yog li tsim cov siv lead ua txuas hniav ntawm cov pores ntawm cov hmoov.

Nyob rau tib lub sijhawm, cov crystals no sib xyaw ua ke, maj mam tsim cov pob loj loj. Txo kev txav mus los cuam tshuam nws txoj kev siv hauv cov lus ntsev. Yog li ntawd, txhawm rau tiv thaiv agglomeration, nws yog ib qho tsim nyog yuav tsum tau ntxiv qhov tsim nyog ntawm tus neeg sawv cev tiv thaiv kab mob thaum lub sijhawm tsim khoom.

Muab yog cov tshuaj tiv thaiv kab mob uas siv rau hauv cov zaub mov-qib potassium chloride, uas tsis muaj tshuaj lom, tsis muaj mob, tsis muaj xim, thiab tsis qab.

Cov txheej txheem txheej txheem: cov khoom siv tshuaj tiv thaiv kab mob rau cov zaub mov qib potassium chloride, uas yog tsim los ntawm D-mannitol, potassium stearate, thiab calcium dihydrogen phosphate, nyob rau hauv D-mannitol, potassium stearate, thiab phosphoric acid Cov ntsiab lus ntawm calcium dihydrogen yog ( 1.25-5):(0.1-0.4):1. Lub purity ntawm D-mannitol, potassium stearate thiab calcium dihydrogen phosphate yog tag nrho cov zaub mov qib.

Ntxiv txoj kev, suav nrog cov kauj ruam hauv qab no:

Kauj Ruam 1. Sib tov thiab pulverize D-mannitol, potassium stearate, thiab calcium dihydrogen phosphate nrog qhov sib piv ntawm (1.25-5): (0.1-0.4): 1 rau daim ntawv ib tug composite anti-caking agent;

Kauj Ruam 2, cov khoom sib xyaw ua ke los tiv thaiv kab mob thiab cov poov tshuaj chloride tiav cov khoom sib xyaw ua ke nrog qhov sib piv 1: (10-100), los ua ib qho khoom ua tiav;

Kauj Ruam 3, ntxiv cov khoom ua tiav rau cov poov tshuaj chloride tom qab ziab, thiab ntxiv qhov sib piv ntawm 1: (20-200).

Ib txoj kev ntub dej rau kev ntxiv cov tshuaj tiv thaiv kab mob rau cov zaub mov-qib potassium chloride muaj cov kauj ruam hauv qab no:

Kauj Ruam 1. Sib tov thiab pulverize D-mannitol, potassium stearate, thiab calcium dihydrogen phosphate nrog qhov sib piv ntawm (1.25-5): (0.1-0.4): 1 rau daim ntawv ib tug composite anti-caking agent;

Kauj Ruam 2, sib tov sib xyaw cov tshuaj tiv thaiv kab mob thiab dej nrog qhov sib piv ntawm 1: (100-200) los tsim cov tshuaj aqueous ntawm cov tshuaj tiv thaiv kab mob;

Kauj Ruam 3, ntxiv cov tshuaj tiv thaiv-caking aqueous tov rau niam cawv ntawm poov tshuaj chloride recrystallization, qhov loj ntawm cov tshuaj tiv thaiv kab mob thiab cov tshuaj potassium chloride tiav yog 1:5000-10000.

2. Kev npaj siab molecular polyethylene polypropylene waterproof membrane

Polyethylene polypropylene fiber ntau yog cov khoom siv tshiab uas tau siv rau xyoo tas los no. Polyethylene polypropylene fiber ntau yog ib hom multi-poly Nws yog ib qho polymer polyethylene polypropylene composite waterproof yob cov ntaub ntawv nrog ib txheej tag nrho.

Nws muaj cov yam ntxwv ntawm qhov loj coefficient ntawm kev sib txhuam, zoo stability, siab mechanical zog, me me coefficient ntawm linear expansion, dav kub adaptability, zoo heev tshuaj tsis kam, huab cua tsis kam, thiab yooj. Nws yog ib qho zoo tagnrho tshiab xyoo pua ntsuab khoom. suav nrog cov kauj ruam npaj hauv qab no:

1) Ntsuas cov khoom siv raw raws li cov hauv qab no los ntawm qhov hnyav: 80-130 qhov chaw ntawm polyethylene resin, 10-20 qhov chaw ntawm talc, 5-10 qhov chaw ntawm silica fume, 5-10 qhov chaw ntawm iav microbeads, 8-16 qhov chaw ntawm potassium stearate, carboxyl pawg 8-18 qhov chaw ntawm styrene-butadiene latex, 10-20 qhov chaw ntawm cov tshuaj tiv thaiv kev laus;

2) Muab talc, silica fume,potassium stearate, thiab carboxylated styrene-butadiene latex rau hauv cov khoom siv ceev ceev, nce qhov kub mus rau 70-80 degree, do ntawm qhov kub ceev rau 8-18min, thiab tom qab ntawd nce qhov kub mus rau 95-100 degree Tom qab ntawd, ntxiv polyethylene resin thiab iav microbeads, nplawm ntawm kev kub ceev rau 10-20min kom tau ib qho sib tov;

3) Muab cov khoom sib tov rau hauv qhov chaw pub mis, extrude nws, ua cov ntaub ntawv polypropylene thiab cov ntawv yas tag nrho los ntawm lub tshuab peb-cov menyuam, dhau los ntawm cov ntawv qhia cov menyuam mus rau lub tsheb laij teb, luas cov npoo, thiab nkag mus rau lub coiler kom tau txais cov khoom siv. khoom.
