Casein kua nplaum yog hais txog tej yam ntuj tso pastes ntawm tsiaj keeb kwm. Nws yog muab los ntawm casein (mis nyuj protein).
Keeb kwm nyob ntsiag to txog leej twg thiab thaum twg thawj zaug sim ua cov khoom ua kua mis. Muaj cov ntaub ntawv hais tias casein kua nplaum tau siv los ntawm cov neeg Iyiv thaum ub. Lub synthesis ntawm paste rau ntawm ib qho kev lag luam nplai tau pib hauv Switzerland thiab lub teb chaws Yelemees thaum ntxov xyoo pua 19th. Cov txheej txheem ntawm kev ua bioglue yog qhov yooj yim heev. Casein kua nplaum hauv lub ntim me me tuaj yeem ua rau nws tus kheej. Yog li, rau nws cov kev npaj, cov tsev cheese yog rubbed los ntawm ib tug sieve thiab ntxuav nrog dej sov, tom qab uas ammonia yog ntxiv dropwise mus rau lub resulting slurry kom txog rau thaum ib tug gelatinous translucent homogenate yog tau. Qhov kev sib txuas tshwm sim yog siv rau cov kws ntoo.
Casein kua nplaum tuaj yeem ua rau lwm txoj hauv kev. Cov mis nyuj muaj roj tsawg kom curdle, muab tso rau hauv qhov chaw sov,tom qab ntawd nws yog lim. Ua li no, nws yog qhov zoo dua los siv cov ntawv lim. Cov lim dej yog ntxuav hauv dej, tom qab ntawd muab tso rau hauv ib lub thawv thiab hau kom tshem tawm cov lipids seem.
Qhov tshwm sim yog qhuav ntawm chav tsev kub. Yog li ntawd, peb tau txais qhov hu ua qhuav casein. Txhawm rau muab nws cov khoom nplaum, dej thiab sodium borate (borax) ntxiv rau nws. Nyob rau hauv kev lag luam tej yam kev mob, mis nyuj protein kua nplaum yog tau los ntawm cov pov tseg ntawm cov mis nyuj kev lag luam. Cov enzyme chymosin (rennet) los yog acids ntxiv rau cov khoom ua tiav ntawm cov mis nyuj skimmed, ua rau cov kua qaub los yog rennet casein. Nws yog qhov nthuav tias ob qho tib si carboxylic (organic) thiab mineral acids tuaj yeem siv rau kev sib txuas ntawm cov kua nplaum, feem ntau yog siv lactic acid.
Cov khoom tseem ceeb ntawm cov nplaum saum toj no yog nitrates, inorganic phosphates thiab calcium caseinate. Mis protein yog insoluble nyob rau hauv dej, hloov nws cov qauv thaum interacting nrog qaug zog daws teeb meem ntawm alkalis los yog acids.
Casein yog phosphoprotein uas muaj tag nrho cov amino acids tseem ceeb. Casein kua nplaum yog zoo rau gluing cov khoom ua los ntawm porcelain, cardboard, ceramics, tawv, ntaub, yas, faience, polystyrene. Feem ntau, cov khoom siv saum toj no yog siv los txuas cov khoom ntoo. Casein kua nplaum yog ib qho tseem ceeb ntawm plywood, woodworking thiab cardboard ntau lawm. Cov khoom tshwj xeeb ntawm bio-adhesive txhim kho cov qauv ntawm cov ntoo, feem ntau siv rau hauv cov txheej txheem ntau lawm.rooj tog. Cov khoom siv ntxiv xws li kerosene, tooj liab sulfate, txiv qaub, rosin, sodium bicarbonate, thiab lwm yam tso cai rau kev siv cov kua nplaum casein thaum ua haujlwm nrog ntau hom ntoo. Cov rooj tog siv casein paste tuaj nrog kos npe "ecological rooj tog" lossis "ib puag ncig tus phooj ywg".
Casein kua nplaum tuaj yeem yuav ntawm txhua lub khw tshwj xeeb. Cov tshuaj no yog ib feem ntawm ntau putties, putties thiab alkali-resistant xim. Kev ntseeg siab thiab lub zog ntawm cov tshuaj casein ua rau nws tsim nyog siv rau txhua qhov chaw uas yuav tsum tau muaj qhov zoo tshaj plaws ntawm tus nqi qis.
