Cov nplaum nplaum tau tsim los ntawm German cov kws tshaj lij ntawm kev txhawj xeeb Henkel nto moo xyoo 1969.

Qhov yooj yim ntawm qhov tsim tau sai sai los ntawm cov neeg siv khoom, ua rau muaj kev vam meej loj rau lub tuam txhab. Nyob rau hauv lub xyoo ntawd ib leeg, ntau tshaj li ib lab cov nplaum nplaum tau muag hauv 121 lub xeev. Txij thaum ntawd los, cov neeg siv khoom tau txais txoj kev ceev thiab huv ntawm gluing. Ntau tshaj li plaub caug xyoo dhau los, tab sis lub chaw ua haujlwm nplaum nplaum, nrog rau cov cwj mem, cwj mem, ntawv clips thiab lwm yam khoom siv, muaj kev txaus siab ntawm qhov chaw. Qhov no tau yooj yim los ntawm kev siv yooj yim, kev lag luam, kev txav mus los thiab kev ua haujlwm ntawm cov khoom.

Cov nplaum nplaum yog hais txog cov khoom siv nplaum. Nws yog tsim rau gluing cardboard, duab, ntawv, textiles. Cov ntaub ntawv yas lo yog yooj yim heev rau siv. Nws cov qauv tsim tuaj yeem ua tau zoo siab, ntxim nyiam, ci ntsa iab thiab nruj. Lub hau airtight kaw tau yooj yim nrog ib qho nias nrog tus cwj pwm nyem thiab tiv thaiv kom qhuav ntawm cov kua nplaum thiab cov evaporation ntawm noo noo. Lub twist-tawm mechanism ntawm tus pas nrig, nyob ntawm lub hauv paus, tso caiseamlessly twist thiab unscrew kem ntawm cov kua nplaum.

Qhov zoo ntawm cov kua nplaum yog pom tseeb:

• dries sai;
• ntxuav tes yooj yim;
• nplaum nplaum thiab ruaj ntseg;
• tsis txhob qias neeg;
• tawm tsis muaj residue;
• tsis deforming qhov chaw;
• tsis tawg;
• siv sparingly;
• dissolving hauv dej.

Vim nws cov khoom siv tshuaj, cov nplaum nplaum tshem tawm cov ntawv sau silicate kua nplaum.

Cov nplaum nplaum yog siv kom huv si thiab sib npaug hauv txheej nyias, tsis txhob kis dhau qhov nplaum nplaum. Qhov sib xws ntawm tus pas tso cai rau koj siv ob txoj kab nqaim thiab ib qho dav, hla tag nrho qhov dav ntawm tus pas nrig txoj kab uas hla. Cov khoom nplaum ntawm cov nplaum nplaum tshwm sim ib nrab ib feeb tom qab siv gluten, uas tso cai rau koj los kho cov teeb meem uas pom nyob rau hauv cov txheej txheem fastening cov ntaub ntawv nyob rau hauv lub sij hawm. Cov kua nplaum zoo yuav tsum tsis txhob muaj pob thiab txhaws, txwv tsis pub, thaum gluing, daim ntawv yuav moistened thiab ua sloppy, thiab tus pas nrig nws tus kheej yuav tig mus rau hauv cov khoom khov.

Cov nplaum nplaum. Composition

Txhua cov nplaum nplaum yog tsim los ntawm cov khoom tsis muaj tshuaj lom biopolymer polyvinylpyrrolidone (PVP) lossis cov khoom tsis muaj xim thiab tsis muaj xim polyvinyl acetate (PVA), uas yog siv los ua cov thickeners. Lawv nplaum tib yam, tab sis cov kua nplaum nrog PVP muaj pes tsawg leeg khaws cov khoom nplaum ntev dua. Nws muaj glycerin ntuj ua moisturizer,

muabntev kev pab cuam lub neej ntawm cov khoom thiab txhim kho cov khoom ntawm cov nplaum. Nws tso cai rau koj kom yooj yim siv cov txheej nyias ntawm cov kua nplaum, txo nws txoj kev noj.

Cov nplaum nplaum tsis muaj cov kuab tshuaj lossis cov xim cuav. Nws muaj kev nyab xeeb kiag li rau tib neeg noj qab haus huv. Qhov zoo tshaj plaws concentration ntawm adhesives kom ceev thiab muaj zog sib txuas ntawm cov ntaub ntawv. Hauv qhov no, daim ntawv yog impregnated tusyees thiab tsis moistened. Ib qho xim liab lossis xiav ntxiv rau cov xim nplaum nplaum, uas ploj tom qab cov nplaum txheej dries. Nws pom meej meej ntawm daim ntawv thiab pab siv cov khoom kom raug thiab raug.
