Casein kua nplaum muab tshuaj txhuam yog hais txog mus rau ib tug tej yam ntuj tso tsiaj. Nws yog tau los ntawm casein (mis nyuj protein). Keeb kwm yog ntsiag to, Thaum twg thiab uas thawj sim muab cov khoom ntawm cov mis nyuj ua khoom. Muaj cov ntaub ntawv uas cov casein kua nplaum siv los ntawm lub ancient Egyptians. Synthesis of lo rau ib tug muaj scale pib nyob rau hauv Switzerland thiab lub teb chaws Yelemees nyob rau hauv thaum ntxov 19th caug xyoo. Tus txheej txheem ntawm kev ua bioadhesives yooj yim heev. Casein kua nplaum nyob rau hauv ib tug me me volume yuav ua nws tus kheej. Yog li, rau qhov kev npaj ntawm cov uas tsis muaj roj tsev cheese nws yog triturated los ntawm ib tug sab cib thiab ntxuav nrog dej sov, ua raws li los ntawm cov dropwise mus rau lub resulting slurry ntxiv ammonia muab gelatinous translucent homogenate. Cov tau compound siv rau joinery.
Casein kua nplaum yuav tsim nyob rau hauv ib tug txawv txoj kev. Muaj roj tsawg mis nyuj rau curdle nws, muab tso rau hauv ib qhov chaw sov, thiab ces lim. Nws yog zoo dua siv lub lim daim ntawv. Lub filtrate tau ntxuav nrog dej, ces muab tso rau hauv ib tug stocking thiab refluxed kom tshem tawm residual lipids. Cov uas ua loj yog qhuav sov li chav nyob. Raws li ib tug tshwm sim, peb muab tau cov thiaj li hu ua qhuav casein. Nyob rau hauv thiaj li yuav impart nplaum zog rau nws ntxiv dej thiab sodium borate (borax). Nyob rau hauv tej kev kawm muaj cov nplaum ntawm cov mis nyuj protein yog tau los ntawm twj ntawm mis nyuj kev lag luam. Cov ua khoom ntawm mis mis nyuj ntxiv enzyme chymosin (rennet) los yog ib tug acid rau paib ib tug acid los yog rennet casein. Nws yog entertaining qhov tseeb hais tias rau lub synthesis ntawm adhesives yuav siv tau raws li carboxylic (organic) thiab miniralnoy acid lactate acid yog siv ntau.
Lub ntsiab Cheebtsam ntawm cov saum toj no nplaum yog nitrates, inorganic phosphates thiab calcium caseinate. Mis protein yog insoluble nyob rau hauv dej, hloov nws cov qauv los ntawm reacting nrog tsis muaj zog alkali kev daws teeb meem los yog acids. Casein - fosfoproteid muaj ib tug ua tiav set ntawm qhov tseem ceeb cov amino acids. Casein kua nplaum zoo rau tsevneeg iav, duab los qhia, ceramics, tawv, daim ntaub, hnab yas, iav yas ua npuas ncauj. Feem ntau cov feem ntau, tus saum toj no cov ntaub ntawv uas yog siv rau kev twb kev txuas ntawm cov ntoo khoom. Casein kua nplaum - ib tug tsim nyog tivthaiv ntawm plywood, txua ntoo thiab ntau lawm cov khoom ntawm cardboard. Lub cim thaj chaw ntawm bioadhesives txhim kho tsob ntoo qauv, feem ntau siv nyob rau hauv qhuav ntawm cov rooj tog. Ntxiv Cheebtsam, xws li kerosene, tooj liab sulphate, txiv qaub rosin, sodium hydrogencarbonate, thiab kuj tso cai rau cov kev siv ntawm lwm yam casein kua nplaum thaum ua hauj lwm nrog ntau yam qib ntawm ntoo. Rooj tog nrog casein kua nplaum los tawm nrog ib tug "tej rooj tog" los yog "ntsuab".
Casein kua nplaum koj yuav tau nyob rau hauv tej spetsmagazine. Qhov no cov ntaub ntawv uas yog ib feem ntawm ntau putties, fillers thiab alkali-resistant xim. Kev ntseeg tau thiab lub dag lub zog casein sib txuas tso cai rau cov kev siv ntawm no formulation tshaj qhov chaw, qhov chaw uas zoo heev zoo tsis muaj kev siv nyiaj yuav tsum tau.
